This is interesting, because that particular article is still regarded

This means, that the 'community' is unable or unwilling to correct the errors within that paper, even if the errors are obvious and easy to

That in turn would suggest, that physicists are collectively cheating

As I argued before, that pair of photons /does/ have mass.
Then you are a hopeless case because a photon has mass _zero_ (in the
Standard Model of particle physics).
That is how it not only can, but why (according to special relativity) it
MUST, propagate at c. We can see that as follows:
The energy dispersion relation for a photon is E = raA -e(K), and one finds >> -e(K) = k c, so E = raA k c = raA/(2-C) (2-C/++) c = (raA/++) c. But
p = raA/++,
so for a photon
E = p c.
The energy-momentum relation for a free particle in Minkowski space is
E^2 = m^2 c^4 + p^2 c^2 <==> m = 1/c reU(E^2 - p^2 c^2)
so
E = p c ==> m = 0. reA
But even if it would /not/ have mass.
It does not.
The source of gravity
_gravitation_
is
not mass, but energy-momentum (the energy-momentum tensor T)
(in general relativity).
Correct.
A photon passing by the sun is attracted to it.
No, it follows the curvature of spacetime.
To conserve
momentum, the sun must also be attracted by the photon!
/Ex falso quodlibet./
F'up2 .relativity
Ah, yet _ex falso quodlibet_ is the compounding of fallacy
and admission of truth's defeat, the conscientious logician
must instead demand _ex falso nihilum_, since _ex falso falsum_.
"Energy" is never "pure energy", always in the quantities
in the forms.
The, "indeterminate forms", vis-a-vis, the undefined,
may make surely for the, "determinate forms",
in the defined.
Solar sails work. If one suggests that it's "ionic wind"
others have that it's light plainly.
Actually, a photon follows about _half_ the curvature of
spacetime, which was enough to improve the computation
of the precession of Mercury.

A simple "death ray" can be fabricated for about $15.
The surface, as it may be, electromagnetic waves
in the brain, are yet only that, and matters of
resonance theory and as well the redundant sorts
of aspects of the brain as electro-chemical soup,
make that many usual accounts of electroencephalograms
are about as advanced scientifically as "Scientologists'".

John Larkin has been the most prolific poster on sci.electronics.design

interested in the content, so your conclusions aren't worth communicating.

My aim isn't a discussion about the metaphysical content, but a
correction of errors.
Therefore I take any single word or equation and analyze, what they
actually say.
Than I check, if that statement makes sense and whether or not it
would fit into that homework of a student.
That's why I don't say 'Einstein was wrong' or alike, because the
actual content is excluded from my comments.
Technically I 'atomize' all statements and check, whether or not they
are correct.
I also checked for formal requirements or proper use of the German
language, for instance.
My counting of errors resulted in 390 comments, which mainly were
about errors. Not all errors were unique, hence there was some
double- counting. But, on the other hand, some annotations covered
more than one error.
All in all it was a fantastically large number of errors and by no
means acceptable, let alone good.
In other words you are a pedant, not a scholar.
No, I'm usually not a pedant.
But I started this project as a proof, that Einstein's text is full of errors (because it was at the beginning a 'battle' between me and
'Dono', who didn't believe me, that Einstein's text was full of errors.)
So, my aim was to find as many errors as possible.
This was also the reason, why I didn't discuss the actual metaphysical content, because it wouldn't make much sense to do that, after the first error was found.
This is so, because theoretical physics has actually very harsh rules
and any tiny error makes a thesis obsolete.
And because I wanted to find as many errors as possible, I had to
continue, even after the thesis was already 'dead'.
That sounds like 'overkill', but that wasn't my intention.
That was also the reason, why I had commented errors, which are more
formal or linguistic.
And because German is my native language, I have some qualification to
check for errors in that realm, too.
Finding grammatical errors in text isn't a reliable indicator that the
text is wrong - even the most competent people make typographical errors
from time to time. Read the psychological literature on "errors of
action" - the take away message is that evolution has given us a
nervous system which only just good enough to do it's job.
Sure, but it's a reliable indicator, that Einstein spoke bad German, too (not only bad English).
The test of a scientific paper is whether it conveys interesting and
novel information to the interested reader. You clearly aren't
interested in the content, so your conclusions aren't worth
communicating.
I was clearly interested in relativity, but not in case of this paper.
My research was not about the ideas Einstein wrote about, but whether or
not the paper was correct.
This is actually a requirement, too, especially in theoretical physics.

Probably you mean "The Division of Occupational Safety and Health (DOSH), better known as Cal/OSHA":
<https://www.dir.ca.gov/dosh/>
It is unlikely that you will be able to cite the original study because
it is more likely that it is all a delusion.
Another likely possibility is that you have misunderstood or are misrepresenting the experiment.
In any case, humans are not rats. They are also not usually exposed to high-intensity electromagnetic radiation in close proximity to their source.
There is no physical reason and no evidence whatsoever that radio waves as used in daily telecommunication caused bodily harm to any human.
The people who are claiming otherwise are not suffering from brain damage because of radio, but from paranoia which is indicative of a brain malfunction which could be caused by prior, unrelated brain damage. It is also indicative of the growing ignorance among the general public that I was talking about: It is human nature to substitute ignorance with conceits and conspiracy theories because that is more convenient than learning.

But as the name implies, it's nuclei of the atoms involved that exhibit

remarkably high magnetic fields to get it to give you a detectable signal.

Resonance imaging (NMR) is a thoroughly different mechanism
than Roentgen rays.
But as the name implies, it's nuclei of the atoms involved that exhibit
the resonance. It's a remarkably low energy effect, and you need
remarkably high magnetic fields to get it to give you a detectable signal.
Nevertheless, it is easily demonstrated in the kitchen

Oh, it's well-known that exposure to high-intensity
radio waves has observable and demonstrable physiological
effects,
If you put your head in a microwave your brain will get cooked.
Some unfortunate radar technicians got bits of their brains warmed up
enough to do observable damage
some have that for example the various post-natal
development syndromes since the 90's are highly correlated
to it ambiently, about a perceived reasoning for a
"Clean, and Quiet, Air Act", where the "Clean Air Act"
was a set of regulatory legislation that can definitely
be related to improved outcomes (in health and life).
Bad statisticians are good at confusing correlation with causation.
A simple "death ray" can be fabricated for about $15.
So what.
The surface, as it may be, electromagnetic waves
in the brain, are yet only that, and matters of
resonance theory and as well the redundant sorts
of aspects of the brain as electro-chemical soup,
make that many usual accounts of electroencephalograms
are about as advanced scientifically as "Scientologists'".
The brain has a lot of electro-chemical structure, but the electrical
activity is slow and the associated electromagnetic waves would have
enormous wavelengths.
If there are electromagnetic resonances inside the skull they'd be at
frequencies way above anything the nervous system could react to
electro-chemically, and the electrical resistance of electrically
conducting body fluids would damp them heavily.
Any suggestion that anything beyond warming up the tissues involved is >>>> going on is a silly as scientology.
Electro-encephlograms are observed at the outside surface of the skull, >>>> and don't resolve activity at the level of individual nerves. It's
rather like monitoring the activity in a city by looking at traffic
density on the motorways.
Epilepsy research and simple modern apparatus mass-produced
in the cellular phone factor platform, may make for that
modern neuroscience makes a lot of wild claims.
The resonance and tuning of radio circuits, including technologies
like heterodyne and synchrodyne, then about old-fashioned pseudo-science >>> like biorhythms, can be quite personalized.
Claims of the DOD Polygraph Institute about the detection of
veracity or lack thereof are common.
That mean old looking Regenstrief or Riegenstrieff Institute,
you'll notice buried among your phone settings many avisos
about health related impacts of technology.
The "research" related privacy laws are very self-contradictory.
That "Neurotourist" is a good little book,
often the researchers interviewed were
self-assured assholes with an un-founded God complex
and myopic confirmation bias.
There are quite a few of them around, but researchers as a population
are no worse than the rest of humanity.
The Alpha Beta Gamma Delta waves or brain waves have
various ways to interpret them, basically about the
linear/non-linear and short/long wave.
None of which seem to be remotely useful.
Resonance theory about things like molecular chemistry
and, you know, magnetic monopoles, is widely employed
in medical imaging and the like.
It certainly wasn't when I was involved in ultrasound imaging from 1976
to 1979. The X-ray and the nuclear magnetic resonance medical imaging
people weren't exactly interested in "resonance theory" either.
Magnetic monopoles were hypothesised by Paul Dirac in 1931.
https://en.wikipedia.org/wiki/Magnetic_monopole
People have been looking for them ever since, but they don't seem to exist.
If radios are un-healthy, then also LED lights are bad for you.
Why would you think that? Light emitting diodes are excited by direct current. There's usually an inverter/rectifier somewhere in their power supply to deliver lots of current into the low voltage drop across the
LED, but they tended to be pretty well shielded (which isn't hard to do).

They'd have about as much chance of getting through sold earth as an

life-time of 2.2usec so if you could get them close to the speed of
light (which would be difficult - it's 206.7682827 times heavier than a electron) they could go about 0.66km (on average) before they decayed.
If you got them very close to the speed of light, time dilation could
let them go further - cosmic ray generated muons do get below the
earth's surface.
The sun might emit them but they don't get anywhere near the earth.
The beam could spread a little, but these guys are Deep State, and they
have a nice budget. They probably built a muon laser.
They might have done, but it wouldn't have produce the effect you claim.

The Batavia/Baikal neutrinophone communicated directly through the

Resonance imaging (NMR) is a thoroughly different mechanism
than Roentgen rays.
But as the name implies, it's nuclei of the atoms involved that exhibit
the resonance. It's a remarkably low energy effect, and you need
remarkably high magnetic fields to get it to give you a detectable signal.

The "resonance" in "nuclear magnetic resonance" is

theory involved.

I've got a Ph.D., in chemistry and while we got lectures on nuclear

"Resonant bonds" are just a bizarre way of describing de-localised electronic bonds. Benzene has six carbon atoms arranged in a flat
hexagonal ring, with one hydrogen atom hanging off each carbon atom . Traditional descriptions say that there are three double bonds and three single bonds around the ring - but that would make the three double
bonds shorter than the three single bonds, and all six bonds are of
equal length. Lecturers who were stuck in the traditional mind set liked
to claim that the molecule resonated between two states where the double bonds and the single bonds swapped places rapidly. It was nonsense, but
it kept them happy.
The Tacoma Narrows bridge was another example.
It's a famous example of an under-damped mechanical resonance - nothing
more.

I believe that, due to magnetic field perturbations in urban
areas, the resonance gets scrambled too quickly to be easily
detectable. In rural areas it should be easier.

You can build in dampers to prevent the resonance from storing a lot of energy or distorting the structure beyond it's elastic limits.
These days mechanical engineers rely on computer simulations to let them anticipate this sort of problem.

The sun might emit them but they don't get anywhere near the earth.
The beam could spread a little, but these guys are Deep State, and they have a nice budget. They probably built a muon laser.

Nope, electron beams can march right through solid earth, in single

Muons can do it too.

NMR was a fairly popular analytical chemistry business for a while. We
made pulsed-field gradient coil drivers and temperature controllers
for Varian.
But superconductive magnets and liquid helium are expensive, and other techniques took over. It was common to visit a lab that had a giant
magnet in the corner, warm and collecting dust. A similar mass spec technique, FTMS, died for the same reason... too expensive.
Agilent bought Varian to get their medical stuff but immediately
killed the NMR operation. I think Bruker still does NMR.
Hospitals prefer cat scans to MRIs these days. Cat scans are much
cheaper.

LEDs should have a warning label "do not stare into LED".
Powerful ones do.
They damage retinas. There are various LED technologies.
You know, like the old, "microwave oven in use" signs.
Never seen one. Domestic microwave ovens are well shielded.
The "resonance" in "nuclear magnetic resonance" is
"resonance theory's".
Only in the sense that some nuclei have a magnetic moment. If you bash
them at the right frequency in the right magnetic field you can get the
magnetic pole rotating at that frequency. There no fancy resonance
theory involved.
"Structural" or "molecular" chemistry is another example
involving resonance theory, like "organic" chemistry,
"resonant bonds".
I've got a Ph.D., in chemistry and while we got lectures on nuclear
magnetic resonance, there was no fancy resonance theory involved in that
either.
"Resonant bonds" are just a bizarre way of describing de-localised
electronic bonds. Benzene has six carbon atoms arranged in a flat
hexagonal ring, with one hydrogen atom hanging off each carbon atom .
Traditional descriptions say that there are three double bonds and three
single bonds around the ring - but that would make the three double
bonds shorter than the three single bonds, and all six bonds are of
equal length. Lecturers who were stuck in the traditional mind set liked
to claim that the molecule resonated between two states where the double
bonds and the single bonds swapped places rapidly. It was nonsense, but
it kept them happy.
The Tacoma Narrows bridge was another example.
It's a famous example of an under-damped mechanical resonance - nothing
more.
There are some steel trestle bridges that happen to
result that driving over them involves more than vertigo.
You can build in dampers to prevent the resonance from storing a lot of
energy or distorting the structure beyond it's elastic limits.
These days mechanical engineers rely on computer simulations to let them
anticipate this sort of problem.
Heh, "remotely useful".
Your idea of what might be "remotely useful" reflects more wishful
thinking than any clear grasp of what is actually going on.
Hm. I have a mathematics degree and sat in computer science for about 20 years. Thinking about going back to the old U. and making a
refresher in the curriculum. Also I have a long-running study
of Foundations and a quite modern theory of mathematics.
Structural or molecular chemistry, a la Brand and Speakman, say,
involves qualitative and quantitative empirical effects above
atomic chemistry.
There are lots of kinds of bonds w.r.t. the various orbits, usually, vis-a-vis the usual tinker-toy model of the atom. _Resonance_ is
a key aspect of, for example, intermolecular and surface forces.
After van der Waals there's Fritz London's dispersion forces,
for examples.
The "remotely useful" was a gentle jibe at the idea of "the remote".
The, "microwave ovens in use" signs were from a time when
the science oven and the pacemaker did not get along.

https://en.wikipedia.org/wiki/Muon
They'd have about as much chance of getting through sold earth as an
electron beam.
Nope, electron beams can march right through solid earth, in single
file, and come out the other end. Its called conduction.
That does depend on electronic conduction. The centre of the earth is metallic - mostly iron. The inner core is solid (and very hot) and
there's a shell of liquid iron about that, but you have to get through
the earth's crust to get there, and that isn't all that conductive.
An electron beam won't make it down to the (mostly) iron core.
Muons can do it too.
Except that they can't and don't. Their 2.2usec lifetime mean that they decay - to two neutrinos and and electron (or a positron for positively charged muon) long before they get anywhere.
You must be thinking of neutrinos. Muons have a
life-time of 2.2usec so if you could get them close to the speed of
light (which would be difficult - it's 206.7682827 times heavier than a >> electron) they could go about 0.66km (on average) before they decayed.
If you got them very close to the speed of light, time dilation could
let them go further - cosmic ray generated muons do get below the
earth's surface.
The sun might emit them but they don't get anywhere near the earth.
The beam could spread a little, but these guys are Deep State, and they >>> have a nice budget. They probably built a muon laser.
They might have done, but it wouldn't have produce the effect you claim.
This is all just what they want you to think. Are you a paid shill for Deep State, or just a useful idjit?

The 'cold fusion idea' has another problem:
there was a strange phenomenon at 9/11, which I would call 'empty
vertical holes'.
This means: there were huge vertical holes inside several buildings,
that contained no debris.
That looked as if someone had shot down from a spaceship with kind of 'starwars weapon', that made matter disappear into hyperspace.
The first building struck wasn't one of the towers, but the customs
building (afaik WTC 6).
This low flat building emitted a puff of dust at a time, when the
twintowers were still standing.
This could be connected to these empty hole, which looked as if someone
had shot from above with a 'teleporter'.
These 'shots' seemingly missed their intended target (most likely the
twin towers), hence had to come from very far away.
But that is all just speculation and possibly something else happend.
But almost with certainty these empty holes were not created by falling debris, because falling material would have left at least 'full holes'.
Another problem was, of course, that the holes came first and only later falling debris.

https://en.wikipedia.org/wiki/Muon
They'd have about as much chance of getting through sold earth as an
electron beam.
Nope, electron beams can march right through solid earth, in single
file, and come out the other end. Its called conduction.
That does depend on electronic conduction. The centre of the earth is
metallic - mostly iron. The inner core is solid (and very hot) and
there's a shell of liquid iron about that, but you have to get through
the earth's crust to get there, and that isn't all that conductive.
An electron beam won't make it down to the (mostly) iron core.
The electrons don't have to go to the center of the earth. They are
only going to the WTC 95 miles away, just below the bulge of the earth.
And earth's crust is a fine conductor. Don't you know what a "ground
rod" is for?
Did you get your degree from Trump U, or what.
Muons can do it too.
Except that they can't and don't. Their 2.2usec lifetime mean that they
decay - to two neutrinos and and electron (or a positron for positively
charged muon) long before they get anywhere.
Muons beam through the earth just like electrons, but faster.
They use
Extenze lotion for maximum endurance. No 2.2 sec whambam. They can go
for weeks.
I can't believe I have to explain all this to a newbie.
You must be thinking of neutrinos. Muons have aThis is all just what they want you to think. Are you a paid shill for

It's just as simple to models waves and particles

that waves beget waves, then also for the accounts of

NMR was a fairly popular analytical chemistry business for a while. We
made pulsed-field gradient coil drivers and temperature controllers
for Varian.
But superconductive magnets and liquid helium are expensive, and other
techniques took over. It was common to visit a lab that had a giant
magnet in the corner, warm and collecting dust. A similar mass spec
technique, FTMS, died for the same reason... too expensive.
Agilent bought Varian to get their medical stuff but immediately
killed the NMR operation. I think Bruker still does NMR.
Hospitals prefer cat scans to MRIs these days. Cat scans are much
cheaper.
But not as good. When I had a ruptured intervertebral disk back in 1988,
I paid extra to get an MRI scan and my clinician was blown away by the >higher resolution it offered - it was about twice as good as he saw in
X-ray based CAT scans. He got my okay to use it for teaching purposes.
And it didn't raise my risk of getting cancer at all.

Great. I got a lot out of Penrose's "Fashion, Faith, and Fantasy (...in Physics)". Or, at least a reputed authority's account that "functional freedom" as he puts it makes for a great schism, a crisis, in physics.
Recall Millikan measuring an electron (or rather, establishing a
charge/mass ratio), then about Rayleigh-Jeans getting to spectroscopy
or, "the Old quantum mechanics", about the discretization, of what
would otherwise be continuous quantities, to discrete quantities,
or "quantization".
The, "standard linear curriculum", it's fair to say that we all
sat the "standard linear curriculum".
Then, a usual account of, the "non-linear", and, the "non-standard",
reflect upon what the "linear curriculum's" account of "linear algebra" simply doesn't include, that mathematics does include.
About definitions of continuity, of course there are the,
"classical expositions of the super-classical", or Zeno's.
Then, a lot of people say that Aristotle, who's the authority in
Western reason since antiquity, is Archimedean in the sense of
there not existing neither infinitesimals nor infinities. Yet,
it is as well so that Xenocrates is part of an account of Aristotle's
as well, the lesser acknowledged accounts of Aristotle that include
both the prior and posterior analytics, makes for "standard
infinitesimals", "iota-values", say, between zero and one an
exact infinitude of them.
Then, this bridges between the classical account of the Pythagorean,
where almost-all is rational, and the modern account of the Cantorian,
where almost-all is transcendental, about Vitali and Hausdorff,
to make for why it's not a paradox to make for three definitions
of, "continuous domains".
We're familiar with, "continuous functions", yet, their definition
holds even if defined on rationals, since it's just an account as
after topology and basically for intermediate-value-theorem / mean-value-theorem / trapezoid rule.
Then, the definition of, "continous domain" itself, is usually
left to the "complete ordered field", the Archimedean field,
in the standard linear curriculum. So, calling those field
reals, then it is yet so that "line reals" or these "iota-values",
are also mathematically, structurally, another example of a
continuous domain. Then there's a third a la "signal reals"
since the Shannon/Nyquist theorem you'll know basically makes
for the supersampling as doubling, to result a continuous
domain after analysis of the rationals.
So, "Mathematical Foundations" itself has structures, features,
of the objects of the "domain of discourse" or our language about
it, the inter-subjective account as after language, structures of mathematical continuity and infinity, that automatically equip
mathematical physics.
I.e., mathematics _owes_ physics more and better mathematics
of continuity and infinity.

I don't think that is correct. Both the sets of natural and rational

which is just plain wrong.
In your ever-so-authoritative opinion.
FYI,
Behaving like a stubborn ass doesn't improve your credibity in general.
Calling people stubborn asses doesn't help yours either.
As a matter of fact, zero to ultra-low frequency NMR
is a flourishing research field these days,
It's cheap to do, so lots of graduate students get stuck with studying
it. The results of their research don't seem to get published in
high-impact journals.
Why can't you just admit that your statement that 'remarkably high
fields are needed to give you a detectable signal'
is just plain wrong?
It does depend on what your are trying to detect. It's certainly true in
a lot of situations of practical interest. Laboratory NMR machines did
go in for high magnetic fields.
As a matter of fact NMR can be done in zero or near-zero fields,
at very low frequencies.
FYI, there is a large Wikipedia article devoted to it.
<https://en.wikipedia.org/wiki/Zero_field_NMR>
That does depend on " highly sensitive magnetic sensors - SQUIDs, magnetoresistive sensors, and SERF atomic magnetometers".
Super-conducting quantum interference devices used to need liquid
helium. Presumably high temperature super conductors could let you get
away with liquid nitrogen, which is lot cheaper.
I was a chemist for long enough to be aware of the difference between
faddish research technique that you only found in research labs and more
practical approaches that you run into in industry.
Since I spent quite a few years working on electron-beam
microfabricators which sold for about a million dollars into
semiconductor fabs that cost about $500 million dollars (back then) my
idea of "industry" covers some fairly high end gear.

If quantum mechanics is never wrong:

The whole point about quantised effects is that they aren't continuous.
Have you have of "deBroglie-Bohm"? Basically their ideas
(or, mostly Bohm) about "real wave collapse" about the usual
quantum formalism the Heisenberg-Scroedinger piucture: make
for a different than the usual Copenhagen interpretation of
quantum mechanics ("It's..., random") that it's not random
and it's not discontinuous, instead since continuum mechanics.
Often enough that was called "hidden variables", then the word
"hidden variables" was publicly shamed, so these times sometimes
it's called "supplementary variables", though, people who stuck
by their own idea of why nature's perfection would demand a
continuum mechanics still have it often enough "hidden variables"
to reflect on Bohm's origins of the ideas and not give it to
the old-wrapped-as-new sort who didn't have to stand up for anything.
Bohr's self-serving Solvay shaming was situationally swept into the ash
heap of history:
Truth by fiat

... [A simplistic version] according to which all the
foundational points of QM had been adequately and
definitely addressed by Bohr at the V Congress of
Solvay - does not fit together with what effectively
happened there. As a matter of fact, three of its
most prominent participants - Einstein, Schr||dinger
and de Broglie - remained forever utterly convinced
that the outlook proposed by Bohr was wide off the
mark of presenting an adequate (and much less
definitive) representation of quantum
phenomena: Einstein never accepted the completeness
of the formulation coming out from the Copenhagen-
G||ttingen axis, and, eight years later, would fire
off an attack, known as the EPR argument, which,
notwithstanding Bohr's prompt attempts to
neutralize it, continues to be argued and commented
about ever since: Schr||dinger maintained his
unwavering belief in a realistic interpretation of
his wave-mechanics; de Broglie, after the 1927
Congress of Solvay has abandoned his pilote-wave
theory (a simplified version of his early theory of
the double solution) converted himself to Bohr's
views; however, he went back to his theory of the
double solution once David Bohm gave it quite a
positive boost with his two introductory articles
on hidden variables.

I'd wonder, have you ever heard any notion that there's a
modern, "crisis", in physics? That is to say, when somebody
like Penrose points out that GR and QM effectively disagree
120 orders of magnitude, and furthermore, there's no room
for gravity in the theory since it would be a constant violation
of energy everywhere, are these considered worthy of interest?
I bought and read Lee Smolin's "the trouble with physics"
https://en.wikipedia.org/wiki/The_Trouble_with_Physics
and passed it on to a friend who did undergraduate physics but
metamorphosed into a statistician. I've also got Roger Penrose's "The
Emperor's New Mind" which was earlier. For years I read "Physics Today"
because my wife was a member of the American Acoustical Society.
I'm well aware that there is talk of a crisis in physics, but if you
want to publish a book about what's going on, you do need to play up the
drama to give the reviewers something to talk about.
Lee Smolin was a player in the game,
not just a spectator.
And Penrose is an idiot, where physics is concerned
as soon as he gets beyond the technicalities of GR. (just imho)
Our world view isn't entirely consistent, and it probably never will be
- the more we learn the harder it becomes to pull everything together
The problem isn't with the world, I think.
It is us humans failing to get the right ideas about it.
How about Mathematics, ..., I'm curious what you think that
Mathematical Foundations is.
For me mathematics is a tool box. I'm well aware that I'm not a
mathematician, but I can follow mathematical advice.
Agreeably, my little video essays are rather dry. That said,
some of the modern AI reasoners eat them up. For example,
in "Logos 2000: physics today" I gathered a bunch of responses
from a sort of model reasoner.
How about "continuity" and "infinity", I'm curious what these
things mean to you.
Finite and continuous functions can be differentiate and integrated.
My undergraduate mathematical education concentrated on them. I'd been
exposed to permutations and combinations at secondary school in
Tasmania, and one of my cousins is a professional statistician, so I did
know that there was a world outside calculus.
I know enough to know that the infinite number of integers is a smaller
number than the infinite number of rational numbers, but I don't get
excited about it.
You shouldn't. It is another thing that you got completely wrong.
I knew some of the linguists that tried to describe natural language in
terms of a generalised phase structure grammar
https://en.wikipedia.org/wiki/Generalized_phrase_structure_grammar
and got to hear when they decided that it didn't work. That's math too.
Hmmm. Of a kind, I guess.
Just packaging it as math isn't enough,

As I argued before, that pair of photons /does/ have mass.
Then you are a hopeless case because a photon has mass _zero_ (in the
Standard Model of particle physics).
That is how it not only can, but why (according to special
relativity) it
MUST, propagate at c. We can see that as follows:
The energy dispersion relation for a photon is E = raA -e(K), and one finds >>> -e(K) = k c, so E = raA k c = raA/(2-C) (2-C/++) c = (raA/++) c. But
p = raA/++,
so for a photon
E = p c.
The energy-momentum relation for a free particle in Minkowski space is
E^2 = m^2 c^4 + p^2 c^2 <==> m = 1/c reU(E^2 - p^2 c^2)
so
E = p c ==> m = 0. reA
But even if it would /not/ have mass.
It does not.
The source of gravity
_gravitation_
is
not mass, but energy-momentum (the energy-momentum tensor T)
(in general relativity).
Correct.
A photon passing by the sun is attracted to it.
No, it follows the curvature of spacetime.
To conserve
momentum, the sun must also be attracted by the photon!
/Ex falso quodlibet./
F'up2 .relativity
Ah, yet _ex falso quodlibet_ is the compounding of fallacy
and admission of truth's defeat, the conscientious logician
must instead demand _ex falso nihilum_, since _ex falso falsum_.
"Energy" is never "pure energy", always in the quantities
in the forms.
The, "indeterminate forms", vis-a-vis, the undefined,
may make surely for the, "determinate forms",
in the defined.
Solar sails work. If one suggests that it's "ionic wind"
others have that it's light plainly.
Actually, a photon follows about _half_ the curvature of
spacetime, which was enough to improve the computation
of the precession of Mercury.

NMR was a fairly popular analytical chemistry business for a while. We
made pulsed-field gradient coil drivers and temperature controllers
for Varian.
But superconductive magnets and liquid helium are expensive, and other
techniques took over. It was common to visit a lab that had a giant
magnet in the corner, warm and collecting dust. A similar mass spec
technique, FTMS, died for the same reason... too expensive.
Agilent bought Varian to get their medical stuff but immediately
killed the NMR operation. I think Bruker still does NMR.
Hospitals prefer cat scans to MRIs these days. Cat scans are much
cheaper.
But not as good. When I had a ruptured intervertebral disk back in 1988,
I paid extra to get an MRI scan and my clinician was blown away by the
higher resolution it offered - it was about twice as good as he saw in
X-ray based CAT scans. He got my okay to use it for teaching purposes.
And it didn't raise my risk of getting cancer at all.
I had a head injury and volunteered for a long-term study, which
involved periodic MRIs. I guess I've had 15. They are slow and boring.
The gradient coils are very noisy.

For something like nucleonics and nuclear theory,
there's that the periodic table of elements,
has another chart for the isotope chart, that's
just more like a wide line on the order of atomic
mass, then that their fundamental identities and
associations, of the nuclear species, might find
the usual account as after organizing for bond orbitals,
as removed from classical as the isotope table is
from the periodic table.
It's similar with other theories about what's "elementary"
and what's "derived", or what's "fundamental" and what's
"derived", as to what is incremental in one, is only
eventual in the other, and vice versa.
For example, a space of geometry, and a space of words,
has usual accounts since, for example, and not to make
a theological account yet only as a common source with
established editions, Genesis 1 starts with a space
for geometry and John 1 starts with a space for words.
Then, geometry itself is sort of the same way,
about points and lines or points and spaces
more thoroughly. For example, via induction,
one may not make a point from dividing lines or
a line from connecting points, yet, there's a
point for deduction that Leibnitz' perfection
of gaplesness "jumplessness" or what eventually
has Hilbert's "postulate of continuity", are
axioms that intend to suffice when otherwise
it would demand a deductive account where
induction is not infallible then to relate
matters of continuity to the geometric series.
It's so that we can't really speak of that
for which there are no words, ultimately
"the ineffable", then that the idea that
man can comprehend the infinite and continuous,
is for matters of reason, besides.

Nope, electron beams can march right through solid earth, in single
file, and come out the other end. Its called conduction.
That does depend on electronic conduction. The centre of the earth is
metallic - mostly iron. The inner core is solid (and very hot) and
there's a shell of liquid iron about that, but you have to get through
the earth's crust to get there, and that isn't all that conductive.
An electron beam won't make it down to the (mostly) iron core.
The electrons don't have to go to the center of the earth. They are
only going to the WTC 95 miles away, just below the bulge of the earth.
And earth's crust is a fine conductor. Don't you know what a "ground
rod" is for?
Sure I do, but it wouldn't carry an electron beam. The word "beam"
implies that the electrons or muons would keep on going in the same direction after they hit the dirt and rocks. They don't keep on going
very far at all - way less than 95 miles. Think inches.
I worked on electron microscopes for nine years (1982 to 1991) and I do
know a bit about electron beams. You clearly know nothing.
Did you get your degree from Trump U, or what.
University of Melbourne. It's been there since 1853, and is currently
the top-ranked university in Australia, and 19th in the world (at least
on one list, not that that means much). Trump University got shut down
as a fraud shortly after it was set up. It didn't last long enough for
me to have been able to get any kind of degree from it, and I'm not
gullible enough to have been in their target demographic. Not being
American put me even father out of reach. As insults go this isn't
plausible enough to be worth making.
Muons can do it too.
Except that they can't and don't. Their 2.2usec lifetime mean that they
decay - to two neutrinos and and electron (or a positron for positively
charged muon) long before they get anywhere.
Muons beam through the earth just like electrons, but faster.
Which is to say, not very far and not all that fast (though they do get farther than electrons).
They use
Extenze lotion for maximum endurance. No 2.2 sec whambam. They can go
for weeks.
One of the tales you tell your girl-friends. Try lying to them about
muon beams - it will take longer for them to find out that you are lying.
I can't believe I have to explain all this to a newbie.
I've been posting to sci.electronics.design since 1996, and my first
comment got published in the Review of Scientific Instruments in 1972.
Only a very dim newbie would make that kind of mistake.

A mathematical physicist like Paul Dirac is an interesting hybrid, but
his biography is titled "The strangest man".
https://en.wikipedia.org/wiki/Paul_Dirac
We were just discussing things like "loop" and "spin" with
regards to the quantum, then, in mathematical physics one
account since the '80's makes for the account of the metric,
which you'll known that in mechanism its establishment is central
as for the metric and norm for length and distance,
there's the "zollfrei metric", as an account of for
something like geometry: that Euclid, and, Poincare,
make for two distinct perspectives on the plane,
Euclid's _smooth_ plane, and Poincare's _rough_ plane.
Now, Poincare was a man, and furthermore a geometer,
and "Euclid" is generally considered a panel, of a man.
So, much like the considerations of Dirichlet, about the
continuous vis-a-vis the differential, where Dirichlet
is another giant of a man, in mathematics and thus all
of mathematical science, Poincare's "rough plane" then
for the zollfrei (or, equivalently enough, "freizoll"),
helps then when thinking about something like "Dirac's
positronic sea", about something like "Einstein's Poincare's
zoll-frei white-hole sea", effecting for a continuous smooth
manifold of space-time and its contents, why it's as well
a continuous reticulation, nowhere smooth, manifold of space-time.
Dirac's function: the Dirac delta, is not-a-real-function,
yet it has a particular real analytical character, and it's
used everywhere throughout analysis and is deeply embedded
in all the usual formalisms of physics.
It's often enough said that physics "the real theory" is at
least these things: a gauge theory.
Here that's simply enough after tendencies and propensities
of oscillation and restitution and attenuation and dissipation
with least-action least-gradient in a sum-of-histories
sum-of-potentials: a potentialistic "the mechanics".
It's a continuum mechanics, ....

You -can- easily demonstrate the effect on the kitchen table.

That does depend on " highly sensitive magnetic sensors - SQUIDs,

Yes. Progress often comes from having more advanced instrumentation.
Developing more advanced instrumentation can let you tackle previously intractable problems. People talk about a solution looking for a problem.
Super-conducting quantum interference devices used to need liquid
helium.
Yes, so what. You have that available, if needed, in a research lab.
If you've got enough money. If you need helium-3 as your refrigerant,
you apparently need political influence as well.
Presumably high temperature super conductors could let you get
away with liquid nitrogen, which is lot cheaper.
Yes. but for research the cost of liquid Helium is not really important.
But only if you have enough money.
I was a chemist for long enough to be aware of the difference between

There is no need to go overly defensive,

I don't see it as a problem.
As for new research technique:
it has to be tried before you can know what can be done with it.
Meanwhile the results are publishable.
It helps if they are publishable in a high impact journal.
When I was a graduate student one of the lecturers kept his students
busy publishing papers on the properties of the simpler conpounds of technicium - the lightest element that hasn't got a stable isotope. He
had contacts in the reactor business that let him get hold of enough of
it to do that kid of work. The results got published in mior league journals.
Since I spent quite a few years working on electron-beam
microfabricators which sold for about a million dollars into
semiconductor fabs that cost about $500 million dollars (back then) my
idea of "industry" covers some fairly high end gear.
Really, there is genuine science and technology
at less than a hundred megabuck a year.
My father got his 25 patents in the paper industry, which - while
capital intensive - isn't in the hundreds of megabucks a year category.
My last job was with Haffmans B/V in Venlo in the Netherlands who made instrumentation for breweries.

I'd wonder, have you ever heard any notion that there's a

120 orders of magnitude, and furthermore, there's no room
for gravity in the theory since it would be a constant violation

I bought and read Lee Smolin's "the trouble with physics"
https://en.wikipedia.org/wiki/The_Trouble_with_Physics
and passed it on to a friend who did undergraduate physics but
metamorphosed into a statistician. I've also got Roger Penrose's "The
Emperor's New Mind" which was earlier. For years I read "Physics Today"
because my wife was a member of the American Acoustical Society.

Lee Smolin was a player in the game,
not just a spectator.
And Penrose is an idiot, where physics is concerned
as soon as he gets beyond the technicalities of GR. (just imho)
Our world view isn't entirely consistent, and it probably never will be
- the more we learn the harder it becomes to pull everything together
The problem isn't with the world, I think.
It is us humans failing to get the right ideas about it.
How about Mathematics, ..., I'm curious what you think that
Mathematical Foundations is.
For me mathematics is a tool box. I'm well aware that I'm not a
mathematician, but I can follow mathematical advice.
Agreeably, my little video essays are rather dry. That said,
some of the modern AI reasoners eat them up. For example,
in "Logos 2000: physics today" I gathered a bunch of responses
from a sort of model reasoner.
How about "continuity" and "infinity", I'm curious what these
things mean to you.
Finite and continuous functions can be differentiate and integrated.
My undergraduate mathematical education concentrated on them. I'd been

Tasmania, and one of my cousins is a professional statistician, so I did >> know that there was a world outside calculus.
I know enough to know that the infinite number of integers is a smaller

You shouldn't. It is another thing that you got completely wrong.

Hmmm. Of a kind, I guess.

Is there any particular idea for which Smolin is known?
I've read some of his books, nothing really comes to mind.
https://en.wikipedia.org/wiki/Lee_Smolin
If "loop quantum gravity" is the thing,
then there are "spin foam networks".
It's a popularizer.
In Lincoln Barnett's book on Einstein, he quotes Einstein
with regards to the role of popularizers, with regards to
physics and the public its perception thereof.

An electron beam won't make it down to the (mostly) iron core.
The electrons don't have to go to the center of the earth. They are

And earth's crust is a fine conductor. Don't you know what a "ground

Sure I do, but it wouldn't carry an electron beam.
You "carry" an electron beam? Did you put it in a stroller on a nice

implies that the electrons or muons would keep on going in the same
direction after they hit the dirt and rocks. They don't keep on going
very far at all - way less than 95 miles. Think inches.
Electrons follow the path of least resistance to the WTC.
I worked on electron microscopes for nine years (1982 to 1991) and I do
know a bit about electron beams. You clearly know nothing.
Nothing is more than you know, cuz everything you think you know is

Muons beam through the earth just like electrons, but faster.

They use
Extenze lotion for maximum endurance. No 2.2 sec whambam. They can go

One of the tales you tell your girl-friends. Try lying to them about
muon beams - it will take longer for them to find out that you are lying.
My women don't want to hear about muons.
Is that what you tried to talk to girls about? Are you still an incel?
I can't believe I have to explain all this to a newbie.

Yes. Progress often comes from having more advanced instrumentation.
Developing more advanced instrumentation can let you tackle previously
intractable problems. People talk about a solution looking for a problem.
More kindly inclined people may call it 'pure science'.
Super-conducting quantum interference devices used to need liquid

Yes, so what. You have that available, if needed, in a research lab.
If you've got enough money. If you need helium-3 as your refrigerant,

Yes. but for research the cost of liquid Helium is not really important.

We seem to have acquired an adequate feel for each other,

As for new research technique:
it has to be tried before you can know what can be done with it.
Meanwhile the results are publishable.
It helps if they are publishable in a high impact journal.
When I was a graduate student one of the lecturers kept his students
busy publishing papers on the properties of the simpler conpounds of
technicium - the lightest element that hasn't got a stable isotope. He
had contacts in the reactor business that let him get hold of enough of

journals.
Minor league professors tend to have minor league students,
who may become in their turn minor league professors.
So it goes, in this, the best of all possible worlds.
Conversely, great names tend to have connections with other great names. Books have been written about it,
like on 'heritability' of Nobel prizes.
There is a nature versus nurture problem here.
One may speculate that the better students

A cat scan takes about a minute.
Getting through the whole procedure takes a lot longer than that. My
local hospital is only a ten minute walk away, but the hospital insists
on keeping me sitting around for about an hour during even the fastest
procedures. They seem to need to keep the patients intimidated. Or at
least acting as if they are intimidated.
The "nuclear medicine" with "technicium 99" is quite targeted.
I felt it helped me a lot with the post-COVID sequelae,

It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid

This may be putting too much faith in the capacity of human language to

For something like nucleonics and nuclear theory,
there's that the periodic table of elements,
has another chart for the isotope chart, that's
just more like a wide line on the order of atomic
mass, then that their fundamental identities and
associations, of the nuclear species, might find
the usual account as after organizing for bond orbitals,
as removed from classical as the isotope table is
from the periodic table.
It's similar with other theories about what's "elementary"
and what's "derived", or what's "fundamental" and what's
"derived", as to what is incremental in one, is only
eventual in the other, and vice versa.
For example, a space of geometry, and a space of words,
has usual accounts since, for example, and not to make
a theological account yet only as a common source with
established editions, Genesis 1 starts with a space
for geometry and John 1 starts with a space for words.
It's so that we can't really speak of that
for which there are no words, ultimately
"the ineffable", then that the idea that
man can comprehend the infinite and continuous,
is for matters of reason, besides.

(don't want to know)
Is there any particular idea for which Smolin is known?
Not that I know of. Best known is loop quantum gravity.
His invention of 'cosmic natural selection'
in combination with anthropic principles
is a complete disaster. (if you ask me)
It is tantamount to an admission of defeat.
Smolin is part of the general failure of string theory and quantum
gravity to produce anything worthwhile.
I've read some of his books, nothing really comes to mind.
https://en.wikipedia.org/wiki/Lee_Smolin
If "loop quantum gravity" is the thing,
then there are "spin foam networks".
It's a popularizer.
The field certainly needs popularising.
And to be fair, Smolin was one of the first to emphasize
that his field, which he identifies with 'physics,
is in a deep crisis. (it still is, btw)
In Lincoln Barnett's book on Einstein, he quotes Einstein
with regards to the role of popularizers, with regards to
physics and the public its perception thereof.
https://www.mathpages.com/home/kmath787/kmath787.htm
I think Einstein generally was a kind man.
He disliked severly criticising people in public.
Worst example perhaps: Velikovsky.
It is known that Einstein told V. in private
that all of his ideas of cavorting planets was bunk.
(and that it detracted from the rest of his work)
E. kept silent when V. published his 'Worlds in Collision' nevertheless.
Kevin Brown there writes a lot of interesting things about physics.
I hadn't encountered his writings.
About 'relativistic mass' and Feynman, in your ref.:
I think Feynman's treatment of relativity in his 'Lectures'
is poor indeed, the worst part of the series.
Feynman was too easy on himself there.
(he should have paid more attention to Wheeler)

A mathematical physicist like Paul Dirac is an interesting hybrid, but

Sort of.

There are lots of different ways to exploit nuclear magnetic
resonance.
The earth's magnetic field is high enough to let you devise
experiments
that can demonstrate the effect on a kitchen table.
Nothing 'sort of'.
You -can- easily demonstrate the effect on the kitchen table.

making their noise, so it didn't worry me.

A cat scan takes about a minute.
Getting through the whole procedure takes a lot longer than that. My
local hospital is only a ten minute walk away, but the hospital insists
on keeping me sitting around for about an hour during even the fastest
procedures. They seem to need to keep the patients intimidated. Or at
least acting as if they are intimidated.
The "nuclear medicine" with "technicium 99" is quite targeted.
I felt it helped me a lot with the post-COVID sequelae,
and everything else, while it's not a usual thing.
(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.
Why the anxiety about mRNA vaccines? At least you know exactly what you
are getting. You can't be as confident about the effect on you because
we've all got about a million single-nucleotide polymorphisms (out of
our three billion nucleotides). Enough people have had their DNA
sequenced that we can hope that we will eventually learn about the interaction between particular vaccines and particular genomes, but
that's going to be a long way off.

So, again for matters of language and the inter-subjective,
we point to all the canon and dogma and doctrine as above,
including revisiting what were deemed _closures_ of mathematical
"openings" (perestroikas, catastrophes) that then instead of
wrongly asserting (axiomatizing) the "ordinary" theory
(eg Russell's retro-thesis of an ordinary inductive set
after Russell's paradox refuting itself), and for the
"Riddle of Induction" instead for these "bridge results"

of the archetectonic is both paleo-classical, and, post-modern.
And correct, ....
Mathematics is just another human language.
A science fiction author - H Beam Piper - wrote a short story
"Omnilingual" that was published in 1957. I read it when it was first
published (while I was still at secondary school).
https://en.wikipedia.org/wiki/Omnilingual
It makes the point that any creature that puts together a periodic table >>> of the elements is going to put together the same data, and that ought
to be a universal Rosetta Stone.
This may be putting too much faith in the capacity of human language to
capture reality.
For something like nucleonics and nuclear theory,
there's that the periodic table of elements,
has another chart for the isotope chart, that's
just more like a wide line on the order of atomic
mass, then that their fundamental identities and
associations, of the nuclear species, might find
the usual account as after organizing for bond orbitals,
as removed from classical as the isotope table is
from the periodic table.
Chemistry is about the electrons. Changing the neutron count has pretty
much zero effect on the chemistry.
It's similar with other theories about what's "elementary"
and what's "derived", or what's "fundamental" and what's
"derived", as to what is incremental in one, is only
eventual in the other, and vice versa.
Rubbish.
For example, a space of geometry, and a space of words,
has usual accounts since, for example, and not to make
a theological account yet only as a common source with
established editions, Genesis 1 starts with a space
for geometry and John 1 starts with a space for words.
Who cares? And why would they?
<snipped more nonsense>
It's so that we can't really speak of that
for which there are no words, ultimately
"the ineffable", then that the idea that
man can comprehend the infinite and continuous,
is for matters of reason, besides.
If you need a new word, invent it. You may have trouble defining it, but
if you felt the need for the new word you should be able to explain why.
It's considerably safer than trying to attach an old word to new concept.

As to why there's one theory, at all, "A Theory",
has that otherwise there's always an infinite
regression, then the idea is that there's an A-Theory,
theatheory, say, that's already ad infinitum instead
of ad absurdam, as, "ab absurdam".
Then practical working theories can simple enough
live in it, and also it makes for weighing and
judging practical working theories without necessarily
being beholden to either.
This is also for a "The Logic".
It's known since antiquity that axioms are stipulations,
and also that any scheme of induction has another
refuting it.
Often it's simple as that there exists real "Truth"
at all, and, you know, "at all".
Then of course there's quite a consideration of
the inter-subjective, then to get above the merely
phenomenological, by supplementing the usual animal's
or machine's sense perceptions with a notion of sense
as object-sense, word-sense, number-sense, time-sense,
and a sense of the continuum, as noumenological,
thusly equipping the considerations of the phenomenological
and noumenological and resolving age-old debates.
Of course, such a theory is "paradox-free",
or rather, it would need be.
Otherwise, don't you have a theory?

Students vary a lot. The nuture problem is about putting the good ones
where they will do well, and some great names were good at doing that
One may speculate that the better students
tend to move out to more promising places,
I've seen a bit of that.
or that great professors may bring out the best in their students.
They tend to send them on to places where their particular skills will
be appreciated, and to get students and post-docs from acquaintances who
think that particular students would do well with them.
Here, at SPR, some of the great lights may tell you
that it is all a conspiracy of Einstein-worshippers.
You can't make a silk purse out of a sow's ear, but a bad supervisor can
wreck a pontential silk purse.
In the olden days, pre-WWII, students tended to travel a lot,
moving between universities, to take courses from reputed professors.
Letters of recommendation played an important part.
Americans and Australians with the good luck of having a scholarship
likewise made European tours, of a few months in several places.
Nowadays there are the Erasmus scholarships and for that,
but that is EU only,

Cardinality establishes a transitive inequality among sets,
where "cardinals" themselves as equivalence classes of sets
having any transitive bijective relation, are, besides zero,
rather too large to be sets in ordinary set theories like ZF(C).

other theories of one relation, like ordinals for

about theories of other objects like those of

The "nuclear medicine" with "technicium 99" is quite targeted.
I felt it helped me a lot with the post-COVID sequelae,
and everything else, while it's not a usual thing.
(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.
Why the anxiety about mRNA vaccines? At least you know exactly what you
are getting. You can't be as confident about the effect on you because
we've all got about a million single-nucleotide polymorphisms (out of
our three billion nucleotides). Enough people have had their DNA
sequenced that we can hope that we will eventually learn about the
interaction between particular vaccines and particular genomes, but
that's going to be a long way off.
Not that it's so relevant to matters of great theory,
yet besides that the mRNA operation is not only like
a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae
are part of the body's viriome and part of messaging
and signaling in the body.
Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm
simply against it since it's dirt cheap and subverts
natural mechanisms, then that ideas like traditional vaccines
with more expensive yet live-type results are having a much
longer run of testing.
The other vaccines in development like the original Oxford
vaccine were much more involved and intended to treat
originally other diseases like those of the T-viridae.
Then TMV post-nasal delivered epitopes and Omicron
crowded it out, it being the successive waves of the
contents of SARS capsid payloads.
Since at least twenty years ago there's a laboratory
where one can simply order DNA, or RNA, assembled to sequence,
then there are virus research labs who make their own.
It's not rocket science, though, it is virus science.
Don't confuse "miRNA rejection" with "vaccine intolerance".

"Riddle of Induction" instead for these "bridge results"
or "analytical bridges" of deduction, this way an account
of the archetectonic is both paleo-classical, and, post-modern.
And correct, ....
Mathematics is just another human language.
Plato, and most mathematicians with him,
will disagree very much with you.
A science fiction author - H Beam Piper - wrote a short story
"Omnilingual" that was published in 1957. I read it when it was first
published (while I was still at secondary school).
https://en.wikipedia.org/wiki/Omnilingual
It makes the point that any creature that puts together a periodic table
of the elements is going to put together the same data, and that ought
to be a universal Rosetta Stone.
And all of physics of course.
Fred Hoyle, in his Andromeda books, also makes use of the same point,
when elaborating on communicating with another intelligence.
(like them knowing about the hydrogen spectrum)
This may be putting too much faith in the capacity of human language to
capture reality.
What has human language got to do with it?

The "nuclear medicine" with "technicium 99" is quite targeted.
I felt it helped me a lot with the post-COVID sequelae,
and everything else, while it's not a usual thing.
(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.
Why the anxiety about mRNA vaccines? At least you know exactly what you
are getting. You can't be as confident about the effect on you because
we've all got about a million single-nucleotide polymorphisms (out of
our three billion nucleotides). Enough people have had their DNA
sequenced that we can hope that we will eventually learn about the
interaction between particular vaccines and particular genomes, but
that's going to be a long way off.
Not that it's so relevant to matters of great theory,
yet besides that the mRNA operation is not only like
a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae
are part of the body's viriome and part of messaging
and signaling in the body.
What a load of ignorant hyperbole. The whole point of the mRA vaccine
against Covid-19 was that it didn't replicate the whole virus but rather
just the segment that latched onto the ACE-receptor.
That segment couldn't mutate much without crippling the capacity of the
virus to infect us, so it was stable target, and it couldn't do anything
else so it wasn't going to get into the human viriome.
Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm
simply against it since it's dirt cheap and subverts
natural mechanisms, then that ideas like traditional vaccines
with more expensive yet live-type results are having a much
longer run of testing.
In other words you haven't got a clue about what was actually gong on.
The other vaccines in development like the original Oxford
vaccine were much more involved and intended to treat
originally other diseases like those of the T-viridae.
Then TMV post-nasal delivered epitopes and Omicron
crowded it out, it being the successive waves of the
contents of SARS capsid payloads.
Since at least twenty years ago there's a laboratory
where one can simply order DNA, or RNA, assembled to sequence,
then there are virus research labs who make their own.
It's not rocket science, though, it is virus science.
Don't confuse "miRNA rejection" with "vaccine intolerance".
Both look identical to pig ignorance. Doctor Johnson talked about
arguing precedence between a flea and a louse. I'm not going to bother.

Somehow I didn't die. Yet, ....
I'm curious, how many times you got the jab,
and whether you were ever, "positive", for COVID.
Here about half the population didn't get the jab.
Stories of reactions are widespread.
Whether it reduced transmissibility is arguable,
since it's clear that 100% of the population
got COVID.
These days pretty much everybody still has
a nominally non-zero COVID virus load.
First time I ever saw a dead body laying out
on the street, ....
That cat was already out of the bag.
Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,
or as rather, toe-to-head.
Don't get me wrong, I'm up on MMR and tetanus
and polio and about hep b, yet, not shingles,
which is also endemic, I contracted the chicken
pox as a youth, and not to forget pertussis or
for that matter D68 or tuberculosis, and within
a few weeks of going to college there went
mononucleosis.
No mRNA, though.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on
my arm, accompanied with other deleterious reactions."
I was like, "Then what happened?". And she said,
"I called my doctor and asked her if this was normal.
And she said 'Yeah right. "Normal"'"
Anyways the TMV and Omicron saved a lot of people.

Getting better all the time !
So actually those criminals at BNL
(you know, scientists, what do you expect)
destroyed the WTC by cold muon catalysed fusion.
(just after the planes hit)
Keep it up !
The idea was, that a facility was used inside a building at the BNL
site, which had the name '911' (still has!).
Only problem with this theory:
BNL is about 95 km away (roughly east) and is located near Montauk in
the Hamptons.
Could have been a little too far away for muons.
Butbutbut... muons can go right through solid earth like it's not there. >>> They come streaming from the sun. 95 miles is just a cakewalk.
The beam could spread a little, but these guys are Deep State, and they
have a nice budget. They probably built a muon laser.
The 'cold fusion idea' has another problem:
there was a strange phenomenon at 9/11, which I would call 'empty
vertical holes'.
This means: there were huge vertical holes inside several buildings,
that contained no debris.
That looked as if someone had shot down from a spaceship with kind of
'starwars weapon', that made matter disappear into hyperspace.
The first building struck wasn't one of the towers, but the customs
building (afaik WTC 6).
This low flat building emitted a puff of dust at a time, when the
twintowers were still standing.
This could be connected to these empty hole, which looked as if someone
had shot from above with a 'teleporter'.
These 'shots' seemingly missed their intended target (most likely the
twin towers), hence had to come from very far away.
But that is all just speculation and possibly something else happend.
But almost with certainty these empty holes were not created by falling
debris, because falling material would have left at least 'full holes'.
Another problem was, of course, that the holes came first and only later
falling debris.
TH
And the plot thickens.
From this I see primo facio evidence of at least THREE grand
conspiracies, plus the muons beamed from Brookhaven.
Remember this is right near where the Montauk Project experiments were carried out which 80 years later Deep State is still trying to coverup.

Mathematics doesn't owe physics anything. Physics exploits tools
developed by mathematicians, which makes physicists customers for the
work of some mathematicians.
That is quite arguable.
Much of mathematics wouldn't exist
without (what was once) new input from physics.
Many a luminary, Von Neumann for example,
has said that mathematics will go stale
without regular fresh input from the natural sciences,
bringing new needs.
A mathematical physicist like Paul Dirac is an interesting hybrid, but
his biography is titled "The strangest man".
https://en.wikipedia.org/wiki/Paul_Dirac
Why discredit him by calling him 'a mathematical physicist'?
He was a theoretical physicist,
He invented the Dirac function, and bra-ket notation. He was notably
more deft with math than most of his contemporaries.
https://en.wikipedia.org/wiki/Bra%E2%80%93ket_notation
He reconciled several ostensibly different quantum theories by pointing
out that they were notational variations of the same basic idea.

There were not many students to begin with.
Most of them had parents who could afford to pay for their studies.
Some poor and obviously very talented boys got scholarships.
Some were adopted by a maecenas who sponsored them.
Women were usually out of luck.

there were about a thousand physicists of all kinds in the whole world,
most of them in Europe.

There's something to be said for computational advantage,
about informational advantage (and intellectual advantage)
as for notions of mechanical advantage, about that
"large, competent, conscientious, co-operative reasoners",
often result thinking alike.
Sometimes the cooperative reasoning produces useful results.
Religion has produced a lot of counter-examples.The MAGA movement is a
more recent case in point. Science is about managing cooperative
reasoning to produce useful results, but then we have IQ tests.
Do you really believe in that pseudo-science?

Mathematics doesn't owe physics anything. Physics exploits tools

That is quite arguable.
Much of mathematics wouldn't exist

Many a luminary, Von Neumann for example,

Why discredit him by calling him 'a mathematical physicist'?
He was a theoretical physicist,
He invented the Dirac function, and bra-ket notation. He was notably
more deft with math than most of his contemporaries.
Arguably. The real inventor was Oliver Heavidise.
(who loved to pester mathematicians with it)
Dirac just gave it another, more elegant name. [1]
( \delta(x) versus D H(x) or 1/2 D \signum(x) )
And that 'most of' will depend on how wide you want to draw the circle.
https://en.wikipedia.org/wiki/Bra%E2%80%93ket_notation
Nothing but notation. You can do without just as well.
Mathematicians object to it,
because the notation assumes without proof that adjoints exist.
(which often needs to be shown, by their standards)
He reconciled several ostensibly different quantum theories by pointing
out that they were notational variations of the same basic idea.
Yes. But imho his most important contribution
was getting quantum field theory started,
[1] Dirac was an electrotechnical engineer by training.
He must have known about Heaviside and his operational calculus.

In the olden days, pre-WWII, students tended to travel a lot,
moving between universities, to take courses from reputed professors.
Letters of recommendation played an important part.
Those with the resources to pay for it did. There weren't many of them.
There were not many students to begin with.
Most of them had parents who could afford to pay for their studies.
Some poor and obviously very talented boys got scholarships.
Some were adopted by a maecenas who sponsored them.
Women were usually out of luck.
For numbers: I have seen estimates that in the year 1900
there were about a thousand physicists of all kinds in the whole world,
most of them in Europe.
Laurence Bragg was one of them, but he did travel with his family.
https://en.wikipedia.org/wiki/Lawrence_Bragg
Americans and Australians with the good luck of having a scholarship
likewise made European tours, of a few months in several places.
Nowadays there are the Erasmus scholarships and for that,
but that is EU only,
(those dumb Brits locked themselves out of it)
There's a memorial travel grant for my wife that offers that to one
graduate student every year at the University of Western Sydney where
she was a professor when she died.
A Good Thing.
But I guess that there are more Australian who want to go to Europe
than the other way round, even nowadays,

I felt it helped me a lot with the post-COVID sequelae,

(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.

Not that it's so relevant to matters of great theory,
yet besides that the mRNA operation is not only like
a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae
are part of the body's viriome and part of messaging
and signaling in the body.
What a load of ignorant hyperbole. The whole point of the mRA

That segment couldn't mutate much without crippling the capacity >>>>>>> of the

Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm
simply against it since it's dirt cheap and subverts
natural mechanisms, then that ideas like traditional vaccines

The other vaccines in development like the original Oxford
vaccine were much more involved and intended to treat

Then TMV post-nasal delivered epitopes and Omicron

contents of SARS capsid payloads.

Somehow I didn't die. Yet, ....

That's poor health care.

Of course they are. Alarmist rumours spread like wildfire.
Whether it reduced transmissibility is arguable,
since it's clear that 100% of the population
got COVID.
It does reduce transmission - people who catch it after having been

These days pretty much everybody still has
a nominally non-zero COVID virus load.
What makes you think that? Long Covid does exist, but it's not all
that
common.
First time I ever saw a dead body laying out
on the street, ....
That cat was already out of the bag.
Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,
or as rather, toe-to-head.
Don't get me wrong, I'm up on MMR and tetanus
and polio and about hep b, yet, not shingles,
which is also endemic, I contracted the chicken
pox as a youth, and not to forget pertussis or
for that matter D68 or tuberculosis, and within
a few weeks of going to college there went
mononucleosis.
No mRNA, though.
It hadn't been invented back then.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on
my arm, accompanied with other deleterious reactions."
I was like, "Then what happened?". And she said,
"I called my doctor and asked her if this was normal.
And she said 'Yeah right. "Normal"'"
Not my experience or that of my wife.
Anyways the TMV and Omicron saved a lot of people.
The mRNA vaccines saved many more.
Yet, ....
Funny, when I got the PCR test they said I didn't have it, ...,
yet, I felt it the first time the grocery checker sneezed,
and feel lucky to have survived the heart attacks and
the respiratory syncytia and the brain fog and the
tendonitis and the dispepsia and the diverticulitis
and all the other associated issues with fibrosis and
defibrosis of a sincerely involved and thorough immune reaction.
Then later all the cancer and remission, ....
Well, discussion about COVID is off-topic, yet much like
talking about common language, and common literature,
is how it falls to the common experience.
That said then, I'm curious about the "Theory of Everything".
Don't try to walk before you can crawl.
By definition it would be singular, ..., then that it's a
real theory of everything including reason and logic and
mathematics, and physics and probability and science,
and the accounts of language and inter-subjectivity,
here there is one and it's a realist's.
When the standard model doesn't cover gravity, it's a bit early to start
talking about a theory of everything.
Chomsky upset linguistic theory with his remarkably powerful approach to
language, even though he doesn't seem to have any idea how the human
language processing system might have evolved.
Slightly incoherent theories that work within their specialised areas
are perfectly fine.
Einstein wasted a lot of his life trying to get a bit closer to a theory
everything. If he'd been less ambitious, he might have been more useful.
Rather, a bit too late, ....
Chomsky's not all that, not much for Whorf either.
Here linguistics is more a course of philology.
You know, I didn't really think that experts trained in
a scientific field could be so ignorant of holistic
dual monism.
Here there's already a theory of everything called "A-Theory".
I've written about it on and off for decades, and from my
video essays "Logos 2000" there "paradox-free reason",
"Foundations briefly", and "A Theory", for starters.

theory at all as universal why naturally according
to reason then that for objects to exist that
mathematical objects exist.
Why should there be only one theory? There are lots of natural
languages, and lots of different words for roughly the same ideas.
Translation between languages is usually pretty straightforward, but
there are exceptions.
"Mathematical platonism" it's usually called,
so commonly that it's even lower-cased like
"euclidean" or "archimedean", then that
"amicus Plato" is a usual account of idealism.
Without some kind of strong mathematical platonism
then logicist positivism is at best "weak",
as basically for the invincible ignorance of
inductive inference.
Logical positivism is a waste of time.
Science is about observations, and you need language to describe your
observations. So far nobody has found any language that works notably
better than any other.
Then, a "strong mathematical platonism", for
the inter-objective as it were, makes for a
"strong logicist positivism", for the inter-subjective
as it is, then for something like a "strong
mathematical universe hypothesis", where objects
really are their numbers and names, not that we
known them, yet that they "are".
The people that thought that chemical atoms were indivisible got a nasty >> shock when nuclear fission showed up.
... And that their relations are mathematical,
so that basically mathematics "is" physics,
the elements of the domain of discourse the
universe of objects, as that mathematics "owes"
physics, since physics has gotten away with itself.
The hypothesis that the relations are mathematical is circular.
Physicists use mathematics to express the relationships they could
observe. Mathematics is largely a way of talking about relationships in
the most abstract way we can manage. It's a language,and we may be able
to invent a better one.
Thus there are necessary accounts of both
the idealistic tradition and analytic tradition.
All one theory, ..., a "mono-heno-theory" a "theatheory".
The "energy" and "entelechy" then are usual notions

Mathematicians, having invented a language, want to claim that it is the >> only possible way of talking about abstract relationships. It's the only >> one we have got, which isn't quite the same thing.

A theory is always an explanation of why an observed process follows the paths we see.
Successful ones explain more observations than less successful ones.
That is they encode more observations. They do tend to be over-simplifications and encode less precisely than we'd like.

Why discredit him by calling him 'a mathematical physicist'?

He invented the Dirac function, and bra-ket notation. He was notably
more deft with math than most of his contemporaries.

He must have known about Heaviside and his operational calculus.
Perhaps. He did his first degree at Bristol in 1921, and went on to do a separate degree in math in 1923. Heaviside was a controversial figure,
and might not have been much cited at Bristol back then.
Looking at Heaviside's wikipedia page, I note that he was the first to
use the impulse function (now known as the Dirac function). If Dirac had known much about Heaviside's work, he probably would have called it the Heaviside function when he first used it.

"Quantum field theory" is just words to me.
That is just too bad.
All of physics is quantum field theory these days,
at least in principle.

Being controversial leads to being well-know.
And Heaviside solved a number of fundamental problems
in electromagnetism, so any electrical engineer
must know about his work.
Even Maxwell's equations are only known nowadays
in the form Heaviside gave them.
Some people even call them the Maxwell-Heaviside equations.
Looking at Heaviside's wikipedia page, I note that he was the first to

'Heaviside function' is already in use for the unit step function,
(don't know about when that name originated, guess well before Dirac)

In the olden days, pre-WWII, students tended to travel a lot,
moving between universities, to take courses from reputed professors.
Letters of recommendation played an important part.
Those with the resources to pay for it did. There weren't many of them.
There were not many students to begin with.
Most of them had parents who could afford to pay for their studies.
Some poor and obviously very talented boys got scholarships.
Some were adopted by a maecenas who sponsored them.
Women were usually out of luck.
For numbers: I have seen estimates that in the year 1900
there were about a thousand physicists of all kinds in the whole world, most of them in Europe.
Laurence Bragg was one of them, but he did travel with his family.
https://en.wikipedia.org/wiki/Lawrence_Bragg
Americans and Australians with the good luck of having a scholarship
likewise made European tours, of a few months in several places.
Nowadays there are the Erasmus scholarships and for that,
but that is EU only,
(those dumb Brits locked themselves out of it)
There's a memorial travel grant for my wife that offers that to one
graduate student every year at the University of Western Sydney where
she was a professor when she died.
A Good Thing.
But I guess that there are more Australian who want to go to Europe
than the other way round, even nowadays,
Jan
PS,
You arrived here to late to see the best anti-Einstein nutter of all.
(an Australian citizen whose name shall not be mentioned)
Verlinde?
Oh, I thought Verlinde was an Australian.
Don't know any "Australian anti-Einstein nutters".
Not much for Verlinde's time-violation, though.
There are some interesting ideas in it.
Einstein doesn't say much except "relativity of, ..., motion",
and "mass/energy equivalence" and "cosmological constant".
He does though make an account of the "spacial" and "spatial"
in "Out of My Later Years", his last word on the matter.
Finlay-Freundlich, or just plain Freundlich if he dropped
his matronymic after he wasn't using it to shield himself
from anti-German sentiment in Scotland, wrote a pretty good
paper on gravity in Einstein's Relativity that's accessible
to all from the Gutenberg project.
https://www.gutenberg.org/ebooks/70793
https://mathshistory.st-andrews.ac.uk/Biographies/Freundlich/
Struick is a pretty decent historian.

Not that it's so relevant to matters of great theory,

a terrible infection yet also like a junk machine

mechanisms, there's also that wild-type Coronaviridae

Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm

These days pretty much everybody still has
a nominally non-zero COVID virus load.
What makes you think that? Long Covid does exist, but it's not all
that
common.
First time I ever saw a dead body laying out
on the street, ....
That cat was already out of the bag.
Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,

Don't get me wrong, I'm up on MMR and tetanus

a few weeks of going to college there went
mononucleosis.
No mRNA, though.
It hadn't been invented back then.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on
my arm, accompanied with other deleterious reactions."
I was like, "Then what happened?". And she said,
"I called my doctor and asked her if this was normal.

Well, discussion about COVID is off-topic, yet much like
talking about common language, and common literature,
is how it falls to the common experience.
That said then, I'm curious about the "Theory of Everything".
Don't try to walk before you can crawl.
By definition it would be singular, ..., then that it's a
real theory of everything including reason and logic and
mathematics, and physics and probability and science,
and the accounts of language and inter-subjectivity,
here there is one and it's a realist's.
When the standard model doesn't cover gravity, it's a bit early to start
talking about a theory of everything.
Chomsky upset linguistic theory with his remarkably powerful approach to
language, even though he doesn't seem to have any idea how the human
language processing system might have evolved.
Slightly incoherent theories that work within their specialised areas
are perfectly fine.
Einstein wasted a lot of his life trying to get a bit closer to a theory
everything. If he'd been less ambitious, he might have been more useful.
Rather, a bit too late, ....
Chomsky's not all that, not much for Whorf either.
Here linguistics is more a course of philology.
You know, I didn't really think that experts trained in
a scientific field could be so ignorant of holistic
dual monism.
Here there's already a theory of everything called "A-Theory".
I've written about it on and off for decades, and from my
video essays "Logos 2000" there "paradox-free reason",
"Foundations briefly", and "A Theory", for starters.

Chomsky's not all that, not much for Whorf either.

You know, I didn't really think that experts trained in

Here there's already a theory of everything called "A-Theory".
I've written about it on and off for decades, and from my
video essays "Logos 2000" there "paradox-free reason",
"Foundations briefly", and "A Theory", for starters.
"He don't know me too well do he."
When I'm interested in linguistics as natural language understanding,
I look to the ACL Anthology https://aclanthology.org,
not whether Chomsky proves to followers he can't parse it.
The multi-pass parser and Tesniere grammars and otherwise
the structural account of grammar, since for example
Panini was the father of grammar, is considered a much
greater account of linguistics for grammar's sake, and
thoroughly the textual, not for phonemes the ape and bird sounds.
Whatmough has a great account of language, and Huppe and
Kaminsky have a good little book on logic and language.

Why should there be only one theory? There are lots of natural

Translation between languages is usually pretty straightforward, but
there are exceptions.
"Mathematical platonism" it's usually called,
so commonly that it's even lower-cased like
"euclidean" or "archimedean", then that
"amicus Plato" is a usual account of idealism.
Without some kind of strong mathematical platonism
then logicist positivism is at best "weak",
as basically for the invincible ignorance of
inductive inference.
Logical positivism is a waste of time.
Science is about observations, and you need language to describe your
observations. So far nobody has found any language that works notably
better than any other.
Then, a "strong mathematical platonism", for
the inter-objective as it were, makes for a
"strong logicist positivism", for the inter-subjective
as it is, then for something like a "strong
mathematical universe hypothesis", where objects
really are their numbers and names, not that we
known them, yet that they "are".

physics, since physics has gotten away with itself.
The hypothesis that the relations are mathematical is circular.

Thus there are necessary accounts of both

A theory is always an explanation of why an observed process follows the
paths we see.
Successful ones explain more observations than less successful ones.
That is they encode more observations. They do tend to be
over-simplifications and encode less precisely than we'd like.
You are a naive positivist, I see.

I felt it helped me a lot with the post-COVID sequelae,
and everything else, while it's not a usual thing.
(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.

that's going to be a long way off.
Not that it's so relevant to matters of great theory,
yet besides that the mRNA operation is not only like
a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae
are part of the body's viriome and part of messaging
and signaling in the body.
What a load of ignorant hyperbole. The whole point of the mRA

Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm
simply against it since it's dirt cheap and subverts
natural mechanisms, then that ideas like traditional vaccines >>>>>>>>> with more expensive yet live-type results are having a much

The other vaccines in development like the original Oxford
vaccine were much more involved and intended to treat
originally other diseases like those of the T-viridae.
Then TMV post-nasal delivered epitopes and Omicron
crowded it out, it being the successive waves of the
contents of SARS capsid payloads.
Since at least twenty years ago there's a laboratory

It's not rocket science, though, it is virus science.

Somehow I didn't die. Yet, ....
I'm curious, how many times you got the jab,
and whether you were ever, "positive", for COVID.
I've had about five or six anti-Covid innoculations. I did eventually >>>>>> catch it after I'd had a couple, and it put me in hospital for four >>>>>> days. My digestive system was where it struck, which was messy and >>>>>> disabling.
Here about half the population didn't get the jab.
That's poor health care.
Stories of reactions are widespread.
Of course they are. Alarmist rumours spread like wildfire.
Whether it reduced transmissibility is arguable,
since it's clear that 100% of the population
got COVID.
It does reduce transmission - people who catch it after having been >>>>>> innoculated don't get as sick, and don't stay sick for as long, so >>>>>> they

These days pretty much everybody still has

common.
First time I ever saw a dead body laying out
on the street, ....
That cat was already out of the bag.
Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,
or as rather, toe-to-head.
Don't get me wrong, I'm up on MMR and tetanus
and polio and about hep b, yet, not shingles,
which is also endemic, I contracted the chicken
pox as a youth, and not to forget pertussis or
for that matter D68 or tuberculosis, and within
a few weeks of going to college there went
mononucleosis.
No mRNA, though.
It hadn't been invented back then.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on
my arm, accompanied with other deleterious reactions."
I was like, "Then what happened?". And she said,
"I called my doctor and asked her if this was normal.
And she said 'Yeah right. "Normal"'"
Not my experience or that of my wife.
Anyways the TMV and Omicron saved a lot of people.
The mRNA vaccines saved many more.
Yet, ....
Funny, when I got the PCR test they said I didn't have it, ...,
yet, I felt it the first time the grocery checker sneezed,

'Heaviside function' is already in use for the unit step function,

Actually it's usually said that physics is a "gauge" theory,
(a field theory), not necessarily a "quantum field" theory.
Retro-finitists of the grainy sort who think that reality
is digital and non-deterministic don't say much, then, do they?
Except "close enough". Which fails, beyond variously
the first or second order, that mathematicians know,
and "physicists" shut up and compute.
When I put "physicists" in quotes like that it means "technicians".
Not that there's anything wrong with those, ...,
just not that they're philosophers of physics
about the truth of the matters, nor that they're
"doing science".

The people that thought that chemical atoms were indivisible got a

physics, since physics has gotten away with itself.
The hypothesis that the relations are mathematical is circular.
Physicists use mathematics to express the relationships they could
observe. Mathematics is largely a way of talking about
relationships in
the most abstract way we can manage. It's a language,and we may be
able
to invent a better one.
Thus there are necessary accounts of both
the idealistic tradition and analytic tradition.
All one theory, ..., a "mono-heno-theory" a "theatheory".
The "energy" and "entelechy" then are usual notions
of the "point-wise" and "space-wise" the quantities.
(Here "mass".)
Mathematicians, having invented a language, want to claim that it
is the
only possible way of talking about abstract relationships. It's the
only
one we have got, which isn't quite the same thing.

Do I dig a ditch faster than a deaf-mute ditch-digger?
I imagine we could talk about it.
Today's bit was "axe grinding". Let's see, one, five,

How about this, "operating system design". I think we could
agree that "operating system design" is a high level practical
matter involving standards and convention.
Ah here's one, it's the old "management consultant" joke.
So, the corporate board really wants to shoehorn value into
their holdings ignorant of the other shareholders, so they
call in a management consultant to really squeeze blood from
the stone from the old factory. The management consultant
shakes it up and gives everyone a good fright for their careers
and the numbers the next day ticked upward so it's considered
a great success. Slavering for more fees, the management consultant
one day finds a maintenance man leaning on his broom onlooking the
factory floor. The management consultant says "what are you doing
today" and the maintenance man says "this" and the management consultant bravely fires him and off he goes. It's going swell
then though, a few days later, somebody slips on a peel, then a
few days later, there's a broken window. One day, there's a new
light on the panel. The next day with a giant crash the entire factory
halts.
So you might figure the epilog is penny-wise pound-foolish,
or vice-versa, or that a stitch-in-time-saves-nine, here
though the management consultant promptly rehires the maintenance
man, or a maintenance man. The maintenance man comes in, finds
a broom, sweeps up a bit, then leans on his broom overlooking the
halted factory. Then the management consultant says "aren't you
going to do something", and the maintenance man says "yeah,
this is about it".
The other story that comes to mind is about the one fellow
who was an engineer and I'd recall his name yet there was
some fact that he was a dwarf. So anyways, some great
industrialist hears about his great experience with electrical
motors and is having a problem with an electrical motor in
his plant. So, the engineer comes in, looks around for a few
days, then at some point makes a chalk mark on a panel, and
says "behind the panel is your problem, fix it". Lo, it was so,
and the technicians got it running. The industrialist is
curious the process of the engineer, and asks for the bill.
The engineer gives him a bill for ten thousand dollars. The
industrialist doesn't really understand the process involved,
and asks for an itemized bill. The engineer shrugs and writes
one up and hands it over and walks off. When the industrialist
reads the bill, it reads: "chalk mark: $5. knowing where to
put the chalk mark: $9995".

You are a naive positivist, I see.

It comes with the territory. Theories can be useful tools. The capacity

It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid

Not that it's so relevant to matters of great theory,

a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae

Also there's that mRNA is more authentically messenger RNA,

mRNA and tRNA and so on were already used. So, I'm

Arguably. The real inventor was Oliver Heavidise.

Yes. But imho his most important contribution

"Quantum field theory" is just words to me.
That is just too bad.
I'm good at learning what I need to, and getting deep into quantum
physics never turned out to be necessary.
All of physics is quantum field theory these days,
at least in principle.
[1] Dirac was an electrotechnical engineer by training.

Being controversial leads to being well-know.
And Heaviside solved a number of fundamental problems
in electromagnetism, so any electrical engineer
must know about his work.
Even Maxwell's equations are only known nowadays
in the form Heaviside gave them.
Some people even call them the Maxwell-Heaviside equations.
Heaviside's version wasn't quite what Maxwell had originally produced.
Looking at Heaviside's wikipedia page, I note that he was the first to

Heaviside function when he first used it.
'Heaviside function' is already in use for the unit step function,
(don't know about when that name originated, guess well before Dirac)
The Heaviside step function is just the integral of the Dirac function.
If Dirac had known about it he'd probably have called the impulse
function the derivative of the step function.

I mostly see Spinoza as an echo of Duns Scotus,

sort of like that Calvinism is disagreeable.
That said Spinoza has an account of an Integer Continuum
which is nice, includes infinity, after Duns Scotus
that "infinity is in", though not quite voicing "univocity".
Dual monism sort of points to Heraclitus, or about the
oldest of the ancient Greek philosophers of the Western
tradition.

"Mathematical platonism" it's usually called,

Without some kind of strong mathematical platonism

Logical positivism is a waste of time.

Then, a "strong mathematical platonism", for

A theory is always an explanation of why an observed process follows

You are a naive positivist, I see.
Not unsuprising, for an engineer.
It comes with the territory. Theories can be useful tools. The capacity
to junk bad and unhelpful theories is a necessary part of the
engineering tool-kit.
Your attitude reminds of Russell's in a sense, Bertrand Russell's,
about the "isolation" and "significance", of theories.
Basically
it's the hypocrisy of the invincible ignorance. Hypocrisy:
hypo- / not enough, -crisy / criticality. Etymology of course
is of the elements of language and thus linguistics, for people
who are textual thinkers, and where language naturally composes.
Something like the grab-bag tool-kit of differential equations
helps show that the conflicting criteria of convergence,
for examples, makes for always checking the outcomes for sanity.
Then, for realists and "Aristotlean realism" and the like,
it sort of results that numbers are ideals. As a sort of
practicing electrical engineer, surely you know that there's
a distinction between "ideal" and "practical" electrical
components, while according to "the theory" there are ideals.
So, having ideals at all hints at least at a weak sort of platonism.
Then the idea that the idealistic tradition and analytical tradition,
or mathematical platonism and logicist positivism, are indispensable
to each other, has then naturally for an account, even for engineers,
where they are of the strong variety.

Just packaging it as math isn't enough,
Is there any particular idea for which Smolin is known?
Not that I know of. Best known is loop quantum gravity.
His invention of 'cosmic natural selection'
in combination with anthropic principles
is a complete disaster. (if you ask me)
It is tantamount to an admission of defeat.
Smolin is part of the general failure of string theory and quantum
gravity to produce anything worthwhile.
I've read some of his books, nothing really comes to mind.
https://en.wikipedia.org/wiki/Lee_Smolin
If "loop quantum gravity" is the thing,
then there are "spin foam networks".
It's a popularizer.
The field certainly needs popularising.
And to be fair, Smolin was one of the first to emphasize
that his field, which he identifies with 'physics,
is in a deep crisis. (it still is, btw)
In Lincoln Barnett's book on Einstein, he quotes Einstein
with regards to the role of popularizers, with regards to
physics and the public its perception thereof.
https://www.mathpages.com/home/kmath787/kmath787.htm
I think Einstein generally was a kind man.
He disliked severly criticising people in public.
Worst example perhaps: Velikovsky.
It is known that Einstein told V. in private
that all of his ideas of cavorting planets was bunk.
(and that it detracted from the rest of his work)
E. kept silent when V. published his 'Worlds in Collision' nevertheless.

About 'relativistic mass' and Feynman, in your ref.:

The recent AI slop attempting to simulate Feynman
is garbage, since not only was he not that pretty,
also he was always rather laconic, that it reminds
me of the AI slop garbage about neo-Stoicism,
which doesn't reflect the ideals and is shamelessly
self-centered.
I.e., it's what Feynman didn't say what usually
made him less than insufferable.
Yeah, that AI slop garbage will always be rejected.

I felt it helped me a lot with the post-COVID sequelae,

(Also had a nice time with the ultrasound tech.)
It seems everybody forget everybody has COVID.
That said, the post-nasal pharyngeal swab with
the Tobacco Mosaic Virus epitopes and the
Omicron the "COVID-Lite" really helped crowd it out.
A shot of remdesivir when the MERS was kicking in
before COVID also seemed to help, and hopefully
the Hep B vaccine was helpful, while though I
never took the mRNA jab and intend never will,
then also I hope to avoid the Crow-vid and Cow-vid
(and, Pig-vid) and avoid food animals with mRNA jabs.

Not that it's so relevant to matters of great theory,
yet besides that the mRNA operation is not only like
a terrible infection yet also like a junk machine
about inflammation and also incredibly cheap and
depending on hijacking the body's RNA replication
mechanisms, there's also that wild-type Coronaviridae
are part of the body's viriome and part of messaging
and signaling in the body.

Also there's that mRNA is more authentically messenger RNA,
it should also be mu-RNA or miRNA I suppose it is, since
mRNA and tRNA and so on were already used. So, I'm

natural mechanisms, then that ideas like traditional vaccines >>>>>>>>> with more expensive yet live-type results are having a much

The other vaccines in development like the original Oxford
vaccine were much more involved and intended to treat
originally other diseases like those of the T-viridae.
Then TMV post-nasal delivered epitopes and Omicron
crowded it out, it being the successive waves of the
contents of SARS capsid payloads.

Here about half the population didn't get the jab.
That's poor health care.
Stories of reactions are widespread.
Of course they are. Alarmist rumours spread like wildfire.
Whether it reduced transmissibility is arguable,
since it's clear that 100% of the population
got COVID.
It does reduce transmission - people who catch it after having been >>>>>> innoculated don't get as sick, and don't stay sick for as long, so they >>>>>> spread less of the virus.

First time I ever saw a dead body laying out

That cat was already out of the bag.
Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,
or as rather, toe-to-head.
Don't get me wrong, I'm up on MMR and tetanus
and polio and about hep b, yet, not shingles,
which is also endemic, I contracted the chicken
pox as a youth, and not to forget pertussis or
for that matter D68 or tuberculosis, and within
a few weeks of going to college there went
mononucleosis.
No mRNA, though.
It hadn't been invented back then.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on
my arm, accompanied with other deleterious reactions."
I was like, "Then what happened?". And she said,
"I called my doctor and asked her if this was normal.
And she said 'Yeah right. "Normal"'"
Not my experience or that of my wife.
Anyways the TMV and Omicron saved a lot of people.
The mRNA vaccines saved many more.
Yet, ....
Funny, when I got the PCR test they said I didn't have it, ...,
yet, I felt it the first time the grocery checker sneezed,

Then later all the cancer and remission, ....
Well, discussion about COVID is off-topic, yet much like

That said then, I'm curious about the "Theory of Everything".

By definition it would be singular, ..., then that it's a

Chomsky's not all that, not much for Whorf either.

You are a naive positivist, I see.
Not unsuprising, for an engineer.
It comes with the territory. Theories can be useful tools. The capacity

engineering tool-kit.
<snip>
Your attitude reminds of Russell's in a sense, Bertrand Russell's,
about the "isolation" and "significance", of theories.
If that was intended to be flattering, it didn't work.
Basically
it's the hypocrisy of the invincible ignorance. Hypocrisy:
hypo- / not enough, -crisy / criticality. Etymology of course
is of the elements of language and thus linguistics, for people
who are textual thinkers, and where language naturally composes.
My ignorance gets defeated at regular intervals, but there's a whole
universe of stuff that I'm going to stay ignorant about, and my
potential areas of ignorance get larger every day with people publishing stuff that I'm never going to get to grips with.
Something like the grab-bag tool-kit of differential equations
helps show that the conflicting criteria of convergence,
for examples, makes for always checking the outcomes for sanity.
Then, for realists and "Aristotlean realism" and the like,
it sort of results that numbers are ideals. As a sort of
practicing electrical engineer, surely you know that there's
a distinction between "ideal" and "practical" electrical
components, while according to "the theory" there are ideals.
Every real component is more complicated than it's ideal version.
Every resistor has a parallel capacitance (which I've had to take into account in real designs) and a series inductance which rarely matters. Capacitors and inductors are worse.
So, having ideals at all hints at least at a weak sort of platonism.
Not exactly. Laziness is the first thing that comes to mind. I always
check other peoples Spice models to see if their inductors have a
parallel capacitance and a series inductance. You can almost always get
them form data sheets, but some people don't bother.
Then the idea that the idealistic tradition and analytical tradition,
or mathematical platonism and logicist positivism, are indispensable
to each other, has then naturally for an account, even for engineers,
where they are of the strong variety.
I see it more as the butter-fingered "keep it simple" tradition.
Good engineers keep things as simple as they can get away with, but they
do need to know when they are cutting corners.

Wolfgang Pauli was the perfect antithesis of an experimental phsyicist.
Experiments stopped working when he walked into a room.
The most dramatic demonstration of the Pauli Effect happened when he
wasn't actually in the room. Somebody was complaining at a conference
that an experiment had stopped working for a couple of hours - "as if
Pauli had stepped into the lab, but he wasn't even in Munich at the
time" and Pauli admitted that he had been stuck in train in Munich for a
couple of hours that day while going somewhere else.
Quarks explain quite a lot of very high energy physics pretty neatly.
The fact that we've got even less chance of getting our hand one of them
than we have of getting our hands on a chunk of dark matter doesn't make
them any less useful as an explanatory device.

These days pretty much everybody still has

What makes you think that? Long Covid does exist, but it's not

Over on sci.math there was a great long thread
"What's the best vaccine for COVID-19?", then
it was appreciated that medical journals opened
up, and it was rather thoroughly studied here.
Matters of macropinocytosis and the like and
issues with platelets and fibrosis has that
the COVID-associated is a head-to-toe disease,

Don't get me wrong, I'm up on MMR and tetanus

which is also endemic, I contracted the chicken

a few weeks of going to college there went
mononucleosis.
No mRNA, though.
It hadn't been invented back then.
I recall one person, over the bookstore counter,
I asked how are today and Bree said "I've been
out a couple days. I got the COVID shot and
overnight a painful baseball-sized welt grew on

"I called my doctor and asked her if this was normal.

start
talking about a theory of everything.

Hm. Well, as a course of "axiomless natural deduction",
then for making an "axiomless geometry", then about mostly reverse-engineering the usual accounts of coordinate analysis
for an integral analysis and an original analysis,
the deconstructive reverse engineering of something like
the fine-structure-constant, or 1/alpha, gets involved pretty
directly with Planck's methods, and showing how they are
incomplete approximations.
Then, what gets involved, is getting "mathematical constants"
and "physical constants" distinguished and sorted out, then
for "running constants" as about continuum mechanics.
For example, if one looks at the roots of x^2 +- x +- 1,
one can notice that one of those roots is phi the golden
ratio, and another is the numerical value of the molar gas
constant. So, the molar gas constant suddently is a mathematical
constant not a physical constant, and suddenly it gets divided
out of Boltzmann constant everywhere, or rather _replaced with
its entire algebraic derivation_ to fulfill that it's an account
of a derivation with its implicits, not a stroke that's all cancelled.
Then, getting into deconstructing Planck, and it sort of involves
where mass/length/time sort of make spirals and about the
dimensional analysis (the dimensioned analysis), then leads
into making mathematical constants as derivations (for
"running constants") then that eventually, that touches
on the finite-structure-constant or 1/alpha.
As for a putative "Theory of Everything" and candidate "Foundations",
the "A-Theory" or theatheory the mono-heno-theory is at least a
theory of everything logical and mathematical to begin.
NIST PDG CODATA posts updated values of physical constants
every few years, that over time have gotten smaller besides
more precise: what kind of science are they doing that
that is your entire world-view.
So, it "is" an analysis of the coordinates and origin and
identity and dimensions about the mathematical and physical
constants of the running constants or "change". It "is"
a gauge theory. It "is" a continuum mechanics.
It "is" a bit more than 11'th graders' linear algebra,
and Buckingham-Pi "dimensionless" analysis.
Heh. At least first it's a true theory with the
universe of mathematical objects in it.
The most dramatic demonstration of the Pauli Effect happened when he

Hm. Well, as a course of "axiomless natural deduction",
then for making an "axiomless geometry", then about mostly reverse-engineering the usual accounts of coordinate analysis
for an integral analysis and an original analysis,
the deconstructive reverse engineering of something like
the fine-structure-constant, or 1/alpha, gets involved pretty
directly with Planck's methods, and showing how they are
incomplete approximations.
Then, what gets involved, is getting "mathematical constants"
and "physical constants" distinguished and sorted out, then
for "running constants" as about continuum mechanics.

the COVID-associated is a head-to-toe disease,

"Mathematical platonism" it's usually called,

"euclidean" or "archimedean", then that
"amicus Plato" is a usual account of idealism.
Without some kind of strong mathematical platonism

My ignorance gets defeated at regular intervals, but there's a whole

Something like the grab-bag tool-kit of differential equations

Then, for realists and "Aristotlean realism" and the like,
it sort of results that numbers are ideals. As a sort of

components, while according to "the theory" there are ideals.
Every real component is-a more complicated than it's ideal version.
Every resistor has a parallel capacitance (which I've had to take into
account in real designs) and a series inductance which rarely matters.
Capacitors and inductors are worse.
So, having ideals at all hints at least at a weak sort of platonism.

Actually it's sort of pointing out that Russell

Then, one might claim he did it for your own good,

The notions of edge cases and corner cases with

it came into the usual vocabulary "the happy case",
what are otherwise error modes and failure modes
make for that at least electronics is still engineering
besides the art of it all, where software engineering

Climate change denial is remarkably foolish.
I saw a proposal to paint a blue line on all buildings in seaside towns
at for example + 5 meter above present mean sea level.
The Greenland ice sheet
https://en.wikipedia.org/wiki/Greenland_ice_sheet
would be good for 7.4 meters of sea if it all slid off into the sea at
once, and similar events happened at the end of the most recent ice age.
The West Antarctic ice sheet
https://en.wikipedia.org/wiki/West_Antarctic_Ice_Sheet
will probably deliver 3.3 meters of sea level rise rather sooner.
Indeed, it could but it is very unlikely that it will.
Again it could happen quite quickly, and there would be no chance of
stopping it if the ice started moving fast and friction heating started
melting the bottom layers of the ice sheet.
Inventing catastrophes is easy.

As of the latest revision of the SI, Boltzmann's constant
is just another conversion factor between units.
There is no longer any physical content to it,

The Boltzmann constant is provided to you in a little table.

For sudden, read a couple of hundred years, and look at the end of the

Think again, or think a bit harder.

The flooding of the Black Sea, which happened at much the same time, did
have more to do with sea level rise. It seems to have been spread over a couple of hundred years, and people would definitely have noticed.

What, you thought Boltzmann constant was a
purely physical constant?
https://en.wikipedia.org/wiki/Boltzmann_constant
Most people who know anything about physics have that idea.
Real physicists understand what are real physical constants,
like \alpha for example, and which constants are meaningless, like c,
because they you tell one about what units you are using.
The exact numerical value of c has mattered to me from time to time.
Good for you that c has an exact numerical value, these days.
Being human, I have to measure things in units, and transform that
measured distance into a propagation delay.
There is nothing but a propagation delay.
Length is by definition measured in (nano)seconds.
Anyone who thinks different is fooling himself.

Pertinent passages pulled from THE HIGGS FAKE: HOW PARTICLE PHYSICS
FOOLED THE NOBEL COMMITTEE by Alexander Unzicker:
Unzicker has studied Physics and has obtained a university diploma in
Physics in 1985. Other than that, however, he is merely an author of popular-scientific books who, because of their content, is not taken seriously in the scientific community.
Incidentally, this particular book was self-published by Unzicker which for
a book about science is always a bad sign as it was not peer-reviewed by a(nother) scientist before publication:
<https://de.wikipedia.org/wiki/Alexander_Unzicker>
Come out with a Number
Today's scientists got widely used to cheap patches when
it comes to fixing some contradiction in an ad-hoc manner,
but the real problems fall into oblivion. Take, for
instance, the fine structure constant, a combination of
the constants c, e, +|0 and h. The number 137.035999... is,
according to Richard Feynman, "one of the great damn
mysteries of physics" and he recommended all good
theoretical physicists should "put this number up on their
wall and worry about it." [...]
None of this has anything to do with the Brout--Englert--Higgs mechanism.
Unzicker's whole argument is a fallacy, and so is yours.

Think again, or think a bit harder.
I should let my imagination run wild because you do?
The catastrophes that really happened, the Storegga slides for example,
had little to do with sea level rise.
The flooding of the Black Sea, which happened at much the same time, did
have more to do with sea level rise. It seems to have been spread over a
couple of hundred years, and people would definitely have noticed.
Again, that Black Sea -catastrophe- never happened.
It was a fund raising trick too,

of the 'the Flood really happened' kind.

Karl Popper doesn't actually say much, he just echoes
scientism the good parts (observability, repeatability,
then emphasizing falsifiability of the theory) then
gets into "social" writing or matter of "human science",
which are plainly oxymoronic.
Kant for scientism just echoes the ancient Greeks.
Don't get me wrong. When you first hear of Karl Popper
and W. Van. O. Quine, and hear that for example "Popper
demands falsifiability in science" and "Quine has ultimate
proper classes and anti-foundational atoms", that seems great,
then they get into empiricism and make un-scientific view the
one and un-logical view the other, so what would have been
a suspension of judgment instead results a less than generous reading.
The notions of Schoperhaauer, Compte, Boole, Russell, Whitehead,
then the whole Carnap school, or "scientism" then "logicist
positivism", those are pretty much Epicurean sophists and
Occam nominalists.
If the "Renaissance" was reinvigorating and finding again
the ideals, and the "Enlightenment" was the reinvigorating
and finding again the analytical setting, it happens a lot
and instead of that it just vacillates between "constructivism"
and "intuitionism", is for an overall wider, fuller, dialectic.
The "technical" parts here are "the dialectic", since for example
Parmenides after Heraclitus, not the messy, spongy "human" parts,
or faux-Hegelians like Wittgentstein or Nietzsche or Heidegger or Marx. ("Anti-Plato's.") Hegel though is great, the Wissenschaft der Logik
of Hegel, the "Science of Logic", is really quite rather great.

For your preferred and self-serving definition of sudden.
What stopped the Gulf Stream seems to have been a lot of fresh water draining into the North Atlantic, and that would have shown up as sea
level rise.
Losing an appreciable proportion of the Greenland ice sheet
would have much the same effect. It would take a while to melt in place,
but there's evidence on the ocean floor that stuff has slid off and
melted (dropping boulders) as it drifted south.

Again, that Black Sea -catastrophe- never happened.
It was a fund raising trick too,
to get money out of credulous American creationists,
of the 'the Flood really happened' kind.
There was certainly an element of that in some of the reports. Something certainly did happen, and it would have made life difficult for those
living in the area while it was going on.
The people who wanted torrents of sea water pouring in from the Mediterranean through the Bosphorus don't seem to found any evidence for that, but the water level went up quite fast over a fairly short time.
https://en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis
talks about 10 to 200 years. Not a sudden catastrophe, but fast enough
that if happened now it would keep a lot civil engineers very busy.

NIST PDG CODATA posts updated values of physical constants

So, it "is" an analysis of the coordinates and origin and

It "is" a bit more than 11'th graders' linear algebra,

Heh. At least first it's a true theory with the
universe of mathematical objects in it.
What, you thought Boltzmann constant was a
purely physical constant?
https://en.wikipedia.org/wiki/Boltzmann_constant
Most people who know anything about physics have that idea.
Real physicists understand what are real physical constants,
like \alpha for example, and which constants are meaningless, like c,
because they you tell one about what units you are using.
The exact numerical value of c has mattered to me from time to time.
Good for you that c has an exact numerical value, these days.
Being human, I have to measure things in units, and transform that
measured distance into a propagation delay.
There is nothing but a propagation delay.
But I couldn't measure that all that accurately, and I need at least a
rough value for the propagation delay before I could build the hardware
on which I could have measured the propagation delay.
Length is by definition measured in (nano)seconds.
Anyone who thinks different is fooling himself.
You may have a preference for expressing it in nanoseconds, but
machinists prefer millimeters. I found it politic to keep them happy.
At least one engineer I knew complained that he was nothing but a
walking table of conversion factors. Life would be easier if that was
the whole job.

various energies and configuration of experiment,
the "regimes of the running constants".
If you don't know how it's done, you can feel free to make fun of it.
It makes you look at bit silly.
Otherwise you're about half-right, in deep space
in a vacuum at a frozen instant in time.
Deep space is a usually a pretty good vacuum, but the gear you need to calibrate isn't much used out there.

You can find lots of wrong and right ends in there,

Science has the advantage that it looks for concensus, and can end up
with a pretty robust idea of right and wrong.
But Greek philosophy -was- what they had for science.
(and for a lot of other things beside that).
There have been quite a few centuries worth of refinements since then.
Peer reviewed international journals do a much better - if still
imperfect - job of error correction and detection than public debates
between the smartest rich guys in town.
Let's agree to disagree about that.

Stern-Gerlach basically demonstrates that it must
be continuum mechanics that it must be quantum mechanics
not simply particle mechanics.
No, it demonstrated that quantum-mechanical systems ("particles") have a property called "(quantum-mechanical) spin", an intrinsic form of angular momentum that is quantized. In particular, the experiment showed that (silver) atoms have this property, and that the projection of their spin can only assume one of two possible values (which for both physical and mathematical reasons were chosen to be +raA/2 and -raA/2; physics justifies the
raA) which makes them behave like that in a magnetic field:

For your preferred and self-serving definition of sudden.
What stopped the Gulf Stream seems to have been a lot of fresh water
draining into the North Atlantic, and that would have shown up as sea
level rise.
That is a theory.
The problem wit it is that it was not accompanied
by a pulse of sea level rise.
For those pulses of sea level rise you might wish to consult <https://en.wikipedia.org/wiki/File:Postglacial_Sea_level_Rise_Curve_and_Meltwater_Pulses_(MWP).jpg>
As for scale, at the very steepest those 'pulses'
had a short term maximum rate of about 50mm/year.
Losing an appreciable proportion of the Greenland ice sheet
would have much the same effect. It would take a while to melt in place,
but there's evidence on the ocean floor that stuff has slid off and
melted (dropping boulders) as it drifted south.
'a while' is the word.

Again, that Black Sea -catastrophe- never happened.
It was a fund raising trick too,
to get money out of credulous American creationists,
of the 'the Flood really happened' kind.
There was certainly an element of that in some of the reports. Something
certainly did happen, and it would have made life difficult for those
living in the area while it was going on.
Sure, the Black Sea rose when the Mediterrenean rose.
Slower and later in fact, because of the large surface area
and the narrow bottleneck formed by the Bosporus.
The people who wanted torrents of sea water pouring in from the
Mediterranean through the Bosphorus don't seem to found any evidence for
that, but the water level went up quite fast over a fairly short time.
https://en.wikipedia.org/wiki/Black_Sea_deluge_hypothesis
talks about 10 to 200 years. Not a sudden catastrophe, but fast enough
that if happened now it would keep a lot civil engineers very busy.
The southern shores of the Black Sea,
where the catastrophe was supposed to have happened,
are relatively steep.
Even a crawling baby could easily have kept ahead of the rising sea.
And there would have been high mountains in plain sight all the time.
Summary: It happened in the wrong place, at the wrong period in time,
and the description doesn't fit.
For the rest all is fine, and it proves that the bible is always right,

Inventing catastrophes is easy.
Why not let the Yellowstone super-volcano explode first?
The catastrophes aren't invented.

For your preferred and self-serving definition of sudden.
What stopped the Gulf Stream seems to have been a lot of fresh water
draining into the North Atlantic, and that would have shown up as sea
level rise.
That is a theory.
The problem wit it is that it was not accompanied
by a pulse of sea level rise.
For those pulses of sea level rise you might wish to consult <https://en.wikipedia.org/wiki/File:Postglacial_Sea_level_Rise_Curve_and_Mel
As for scale, at the very steepest those 'pulses'
had a short term maximum rate of about 50mm/year.
Losing an appreciable proportion of the Greenland ice sheet
would have much the same effect. It would take a while to melt in place, >> but there's evidence on the ocean floor that stuff has slid off and

The catastrophes aren't invented.

The southern shores of the Black Sea,
where the catastrophe was supposed to have happened,
are relatively steep.
Even a crawling baby could easily have kept ahead of the rising sea.
But if it's parents had been growing crops on an area that got
submerged, the baby might not have had the energy to crawl far enough or
fast enough.
How far-fetched can you get?
And there would have been high mountains in plain sight all the time.
Which aren't particularly rich in food resources.
The point is that they are visible all the time,
in direct conflict with the Noachian flood story.
Summary: It happened in the wrong place, at the wrong period in time,
and the description doesn't fit.
It happened in the obvious place - on the shoreline, which moved.
No lack of shore lines that move, all over the world.
The obvious one is the Persian Gulf moving into Eufrates/Tigris delta.
(much faster, and just where it is wanted)
There is where the story that those shepherds from the hills ripped off really happened,

That depends on how fast we cut our carbon emissions.
Well, yes, humans exhale CO2.
But, please, don't stop to do that.
But in case of sea-level rising due to climate change I can assure you,
that emitting CO2 by you has absolutely zero effect upon sea-levels.
First:
there is actually 'climate-change' as a real phenomenon in many places.
But that isn't caused or even related to CO2, but has other reasons.
Mainly the water is the key to understand weather. Climate is strictly
local and the result from what is happening in a certain region.
For instance lets take a really nasty city, in respect to climate.
Lets take, for instance, Dhaka in Bangladesh.
What you see is a totally overcrowded city.
More than 24 Million people are cramped into a city build for 10% of
that number.
Would you really believe, that this would not influence climate?
But how you exhale has nothing at all to do, whether or not the icesheet
of Greenland could slide into the ocean.
The real cause is actually the water, because people need water, space
to stay, to travel and to grow food.
All of this has influence upon how much water the ground could evaporate
and that in turn has influence upon the creation of clouds and that in
turn changes the climate.

That is a theory.
The problem wit it is that it was not accompanied

Think again, or think a bit harder.

The flooding of the Black Sea, which happened at much the same
time, did have more to do with sea level rise. It seems to have

Again, that Black Sea -catastrophe- never happened.
It was a fund raising trick too,
to get money out of credulous American creationists,
of the 'the Flood really happened' kind.

Sure, the Black Sea rose when the Mediterrenean rose.
Slower and later in fact, because of the large surface area
and the narrow bottleneck formed by the Bosporus.

The southern shores of the Black Sea,
where the catastrophe was supposed to have happened,
are relatively steep.
Even a crawling baby could easily have kept ahead of the rising sea.
But if it's parents had been growing crops on an area that got
submerged, the baby might not have had the energy to crawl far enough or >> fast enough.
How far-fetched can you get?
Think about Doggerland (now in the middle of the North sea between
England and the Netherlands).
There were people living out there at the end of the last ice age.
https://en.wikipedia.org/wiki/Doggerland
It got inundated by a series of fairly dramatic events. Crawling babies wouldn't have done well.
"It is estimated that up to a quarter of the
Mesolithic population of Britain lost their lives".
The sea level rise tied up in the West Antarctic and Greenland ice
sheets isn't going to show up as smooth and gradual rise, any more than
the sea level rises that happened at the end of the most recent ice age did.
And there would have been high mountains in plain sight all the time.
Which aren't particularly rich in food resources.
The point is that they are visible all the time,
in direct conflict with the Noachian flood story.
Who was promoting that?
Summary: It happened in the wrong place, at the wrong period in time,
and the description doesn't fit.
It happened in the obvious place - on the shoreline, which moved.
No lack of shore lines that move, all over the world.
The obvious one is the Persian Gulf moving into Eufrates/Tigris delta. (much faster, and just where it is wanted)
There is where the story that those shepherds from the hills ripped off really happened,
And you know because your time machine took you there?
The 'nym-shifting troll demonstrated their utter ignorance again:
[...] A quantum is a domain,
No, it is not. It is an elementary excitation state of its quantum
field.
Navigation sats have no cesium clocks to begin with.
They use less accurate ones (rubidium and/or hydrogen)
that are steered to agree with the more accurate master clocks on the ground, at USNO for example.

Good for you that c has an exact numerical value, these days.

There is nothing but a propagation delay.
But I couldn't measure that all that accurately, and I need at least a

That's part of being a competent experimenter.
Length is by definition measured in (nano)seconds.

Nobody still there did well.
The run-up of the tsunamis was up to 25 meter in Scotland.
Those tsunamis had nothing to do with sea level rise.
(and they couldn't have been forseen, even today)
Once known about, the Norwegians did a thorough investigation
to make sure that the three of them were all there are going to be.
(before starting their oil exploitation)
"It is estimated that up to a quarter of the
Mesolithic population of Britain lost their lives".
Quite possible, but the distribution of the population in Britain
at the time isn't really well known,
so you can invent percentages to suit.
Oxfordians wouldn't have had a problem.
The sea level rise tied up in the West Antarctic and Greenland ice
sheets isn't going to show up as smooth and gradual rise, any more than
the sea level rises that happened at the end of the most recent ice age did.
Pure fantasy on your part.
If you would want to acquire some more realistic knowledge
you might want to have a look at: <https://www.nature.com/articles/s41586-025-08769-7> (open source)
which is based on real measurements rather than fantasy.
Conclusion: there are no episodes of catastrophis sea level rise
in the Early Neolithc. (in the North Sea, so nowhere else)
Measured sea level rise is steady, and of order of 10 mm/year.
(comparable to what is measured nowadays)
And there would have been high mountains in plain sight all the time. >>>>Which aren't particularly rich in food resources.

as if it is brilliant discovery on your part
is not conductive to informed discussion.

The sea level rise tied up in the West Antarctic and Greenland ice

That depends on how fast we cut our carbon emissions.
Well, yes, humans exhale CO2.
But, please, don't stop to do that.
But in case of sea-level rising due to climate change I can assure
you, that emitting CO2 by you has absolutely zero effect upon sea-levels.
You can assure me as much as you like, but you don't strike me as having
a clue about what you are talking about.
First:
there is actually 'climate-change' as a real phenomenon in many places.
But that isn't caused or even related to CO2, but has other reasons.
Mainly the water is the key to understand weather. Climate is strictly
local and the result from what is happening in a certain region.
Climate isn't remotely local. When the El Nino and La Nina states show
up, they are most clearly visible in the ocean surface temperatures in
the Pacific around the equator. They change the rainfall patterns in
Eastern Australia. Weather is about moving heat from the equator towards
the poles, and it ties into ocean currents that do the same job. We can
see the ones flowing on the surface. The deep currents that handle the return flow are now being documented by the Argo Buoy program, but there
are only a couple of thousand of them and a great deal of ocean.

'Climate' was once defined as the mean local state of the atmosphere.
But once the scum took over, that was changed and the word was used to describe the word as a whole.
This was necessary, because the scandal is meant as justification of
what I would call 'tax on air', which is apparently planned for the
first world countries, where 'climate' is more or less OK, even it could
be a little warmer in many areas.
The real problem occurs, of course, in much poorer regions, where
pollution and population growth is out of control.
But even if the countries in that region are actually responsible for
what they do, they are far too poor to allow to extract a lot of tax.
So, the industrialized world is blamed for what they are not responsible
and what they could not change efficiently.
The means to justify this bunk is actually a redefinition of the word 'climate', which is now used to describe the mean temperature of the
entire Earth.
This was needed, because otherwise countries in the first world could rightfully claim, that they were not responisible and had nothing against warmer 'climate'.

Time is a universal parameter of most theories of mechanics,
and the useful ones.
Too bad for most theories of mechanics; too
bad for your moronic physics.
Time is a universal _absolute_ parameter.
What you actually mean is 'universal'.
You have, for some odd reasons, the idea, that the entire universe must
but universally synchronized.
About space-contraction as length-contraction and
time-dilation together, has that clocks "slow" or
"meet" about differences between "space-contraction-linear"
and "space-contraction-rotational", breaking out the
"space-contraction" as "-linear" and "-rotational"
instead of "length-contraction" and "time-dilation".
Even stranger is, that clocks and time are used interchangeable.
But a clock is a man-made device, while time is a natural phenomenon and
not supposed to depend on clocks (because nature is not man-made).
This is a very euclidean account.
Bad enough

It's a "clock hypothesis", that a "clock hypothesis" is that
the universe has one, a "clock hypothesis" is usual in many
accounts of physics the theory, for example Einstein has one.
Most people think he doesn't because they're confused by aspects
of relativity theory, and about Minkowski then the space-time,
yet he says so, Einstein, for example in "Out of My Later Years".
Anything else eventually violates causality, or the usual idea
that there's a physics at all, a "cosmological principle".

My understanding of time begins with MAN AND TIME by Priestley. Although
it's intellectually imprudent to excerpt a single sentence to summarize
his survey:
"One metaphysical idea of Time: We do not discover Time but
bring it with us; it is one of our contributions to the
scene; our minds work that way."
Shadbolt shares similar sentiments:
Could Einstein's definition of time have been one of the
greatest hindrances to the advancement of human knowledge
that history has ever known?
About Time: Einstein Was Wrong
Discussions about how to define 'time' inevitably become
philosophical debates. As I've noted previously, 'everybody
knows what time is until they try to define it'. For the
framework of this article, let's limit our discussion about
time to looking at Einstein's definition of time in special
relativity and contrasting that with the understanding of
time in quantum mechanics.
In special relativity, Einstein defined time simply as a
measure of how long an event takes, as measured by a clock.
This is a sensible, straightforward measure. For example,
the time it took me to read the previous paragraph, measured
by a stopwatch, was 10 seconds. In special relativity, clocks
are used as an objective standard for measuring the time
intervals of physical processes.
The problem is that this sensible measure of time becomes time
itself.
For example, if an atomic clock is observed to slow down (it
registers fewer oscillations of the caesium atom at a different
altitude), this is not understood as a change in the clock's
operating speed. In relativity, this slowing is interpreted
as a slowing in the rate of time itself.
... this mistaken interpretation commits an error that Sir
Isaac Newton warned us against in his Philosophiae Naturalis
Principia Mathematica.
Newton wrote, 'Relative quantities are not the quantities
themselves whose names they bear, but sensible measures of
them.. and by the names time, space, place, and motion their
sensible measures are to be understood; and the expression
will be unusual if the measured quantities themselves are
meant. ..those violate the accuracy of language, who interpret
these words for the measured quantities.'
Putting this concept into the modern context, even when the
motion of light in a vacuum is used as the standard 'clock' to
measure time, it is still just a physical entity that can be
influenced by other physical processes, known or unknown. This
was Einstein's biggest mistake; he employed a physical process
(the motion of light) to serve as a stand-in for time itself.
In Newton's words, he expressed a sensible measure of time as
time itself.
French philosopher Henri Bergson, a contemporary of Einstein,
disputed relativity's portrayal of time by arguing that there
is a difference between time itself and what clocks display.
Clocks display arbitrary fractions of periodic events such as
the motion of the Sun across the sky (as shown on a sundial),
grains of sand moving through an hourglass, the number of
swings of a pendulum, or the number of oscillations of a
caesium atom (the current standard), but this is not the
physical reality of time itself. The physical reality of time
is the standard against which we can compare these events.

Seems I say there's "A Theory" that's constant, consistent,
complete, and concrete, a paleo-classical post-modern account,
classical and modern, super-classical and extra-ordinary,
according to the canon, dogma, and doctrine, about the
principles of inverse and thorough reason, then that
gives axiomless natural deduction and then axiomless geometry,
and after strong mathematical platonism and strong logicist

For once a statement by you which is NOT word salad, and with which I fully agree.
In fact, the idea that a theory about Nature does not stand on its own, merely because an "eminent" philosopher has formulated it or it sounds convincing or is internally logically consistent; but that it needs to be *tested* against Nature, so it needs to be *testable*, and thus
*falsifiable* -- it needs to make *quantifiable* statements so that it can

where the clock is located. Nobody is going to confuse the ruler used to measure distance with the distance measured.
But a clock is a man-made device, while time is a natural phenomenon
and not supposed to depend on clocks (because nature is not man-made).
Why would anybody think that?

Time is a universal parameter of most theories of mechanics,
and the useful ones.
But time must be a LOCAL parameter ONLY!
It is total bunk to assume, that an 'external' clock would exist,
which synchronizes everything in the universe.
Clocks don't exist to synchronise anything. They can be part of a local system which synchronises some local action to an event which has been observed from that location. Granting the bulk of the universe is
expanding away from any given point at a speed which is increase with
time and distance time dilation alone makes the idea of perfect synchronicity untenable.

You can assure me as much as you like, but you don't strike me as
having a clue about what you are talking about.
First:
there is actually 'climate-change' as a real phenomenon in many places. >>>>
But that isn't caused or even related to CO2, but has other reasons.
Mainly the water is the key to understand weather. Climate is
strictly local and the result from what is happening in a certain
region.
Climate isn't remotely local. When the El Nino and La Nina states
show up, they are most clearly visible in the ocean surface
temperatures in the Pacific around the equator. They change the
rainfall patterns in Eastern Australia. Weather is about moving heat
from the equator towards the poles, and it ties into ocean currents
that do the same job. We can see the ones flowing on the surface. The
deep currents that handle the return flow are now being documented by
the Argo Buoy program, but there are only a couple of thousand of
them and a great deal of ocean.
'Climate' was once defined as the mean local state of the atmosphere.
But once the scum took over, that was changed and the word was used to
describe the word as a whole.
That happened when weather forecasting became practical. People got to realise that high pressure areas and low pressure areas travelled across
the country in roughly predictable directions at roughly predictable
speeds. Electric telegraph system got fast enough after the 1850's for observers to keep track of them. If you think that those people were
scum, you can comfort yourself with the thought that they are all dead.
Australia's "Telegraph" Todd was one of them, and he was highly
respected at the time (and his grandson, Lawrence Bragg was Australia's first Nobel Prize winner).
This was necessary, because the scandal is meant as justification of
what I would call 'tax on air', which is apparently planned for the
first world countries, where 'climate' is more or less OK, even it
could be a little warmer in many areas.
The real problem occurs, of course, in much poorer regions, where
pollution and population growth is out of control.
But even if the countries in that region are actually responsible for
what they do, they are far too poor to allow to extract a lot of tax.
So, the industrialized world is blamed for what they are not
responsible and what they could not change efficiently.
The industrial revolution did involve burning a lot of fossil carbon
which has had visible and now well-documented effect on the climate over
the last century. Now that we have got the point where the cheapest way
of generating electric power is with solar cells, and wind turbines are
the second cheapest, we can stop burning fossil carbon and messing up
the climate even more and still manufacture stuff in huge volumes, and
more cheaply and efficiently than we used to. We haven't actually got to
the point where we are burning less fossil carbon than we did last year,
but we are close to it, and China is making a lot of money out of making remarkably cheap solar cells in enormous volumes (which is why they can
make them cheaply).
The means to justify this bunk is actually a redefinition of the word
'climate', which is now used to describe the mean temperature of the
entire Earth.
Climate got redefined when we could collect enough data around the world
to realise that the weather around the world was connected. Satellites
in orbit looking down at the atmosphere did a much better job than
weather observatories on the ground has done, but ground based observers
had been doing a pretty good job for about a century before we had satellites to do it better.
This was needed, because otherwise countries in the first world could
rightfully claim, that they were not responisible and had nothing
against warmer 'climate'.
The low lying islands in the Pacific aren't too worried about a warmer climate in their area, but they are deeply worried about the effects of
a warmer climate on the ice sheets on top of Greenland and West Antarctica.
These are are going to slide off and melt over the next few centuries,
and produce about 10 meters of sea level rise, which will submerge a lot
of low lying islands. The Dutch sea defenses are going to need work too.

It's a "clock hypothesis", that a "clock hypothesis" is that

Most people think he doesn't because they're confused by aspects
of relativity theory, and about Minkowski then the space-time,

Shadbolt shares similar sentiments:
Could Einstein's definition of time have been one of the
greatest hindrances to the advancement of human knowledge
that history has ever known?
About Time: Einstein Was Wrong
Discussions about how to define 'time' inevitably become
philosophical debates. As I've noted previously, 'everybody
knows what time is until they try to define it'. For the
framework of this article, let's limit our discussion about
time to looking at Einstein's definition of time in special
relativity and contrasting that with the understanding of
time in quantum mechanics.
In special relativity, Einstein defined time simply as a
measure of how long an event takes, as measured by a clock.
This is a sensible, straightforward measure. For example,
the time it took me to read the previous paragraph, measured
by a stopwatch, was 10 seconds. In special relativity, clocks
are used as an objective standard for measuring the time
intervals of physical processes.
The problem is that this sensible measure of time becomes time
itself.
For example, if an atomic clock is observed to slow down (it
registers fewer oscillations of the caesium atom at a different
altitude), this is not understood as a change in the clock's
operating speed. In relativity, this slowing is interpreted
as a slowing in the rate of time itself.
... this mistaken interpretation commits an error that Sir
Isaac Newton warned us against in his Philosophiae Naturalis
Principia Mathematica.
Newton wrote, 'Relative quantities are not the quantities
themselves whose names they bear, but sensible measures of
them.. and by the names time, space, place, and motion their
sensible measures are to be understood; and the expression
will be unusual if the measured quantities themselves are
meant. ..those violate the accuracy of language, who interpret
these words for the measured quantities.'
Putting this concept into the modern context, even when the
motion of light in a vacuum is used as the standard 'clock' to
measure time, it is still just a physical entity that can be
influenced by other physical processes, known or unknown. This
was Einstein's biggest mistake; he employed a physical process
(the motion of light) to serve as a stand-in for time itself.
In Newton's words, he expressed a sensible measure of time as
time itself.
French philosopher Henri Bergson, a contemporary of Einstein,
disputed relativity's portrayal of time by arguing that there
is a difference between time itself and what clocks display.
Clocks display arbitrary fractions of periodic events such as
the motion of the Sun across the sky (as shown on a sundial),
grains of sand moving through an hourglass, the number of
swings of a pendulum, or the number of oscillations of a
caesium atom (the current standard), but this is not the
physical reality of time itself. The physical reality of time
is the standard against which we can compare these events.

But time must be a LOCAL parameter ONLY!
It is total bunk to assume, that an 'external' clock would exist,
which synchronizes everything in the universe.
Clocks don't exist to synchronise anything. They can be part of a
local system which synchronises some local action to an event which
has been observed from that location. Granting the bulk of the
universe is expanding away from any given point at a speed which is
increase with time and distance time dilation alone makes the idea of
perfect synchronicity untenable.
If nothing synchronizes remote systems, then how could we rightfully
assume, that remote systems share the same time?
The nearest star to Earth is about three light-years away.
In between Earth and proxima Centaury we have essentially nothing.
So, what would hinder the time in Proxima Centaury to run backwards?

Mainly the water is the key to understand weather. Climate is
strictly local and the result from what is happening in a certain
region.
Climate isn't remotely local. When the El Nino and La Nina states
show up, they are most clearly visible in the ocean surface
temperatures in the Pacific around the equator. They change the
rainfall patterns in Eastern Australia. Weather is about moving heat
from the equator towards the poles, and it ties into ocean currents
that do the same job. We can see the ones flowing on the surface.
The deep currents that handle the return flow are now being
documented by the Argo Buoy program, but there are only a couple of
thousand of them and a great deal of ocean.
'Climate' was once defined as the mean local state of the atmosphere.
But once the scum took over, that was changed and the word was used
to describe the word as a whole.
That happened when weather forecasting became practical. People got to
realise that high pressure areas and low pressure areas travelled
across the country in roughly predictable directions at roughly
predictable speeds. Electric telegraph system got fast enough after
the 1850's for observers to keep track of them. If you think that
those people were scum, you can comfort yourself with the thought that
they are all dead.
Australia's "Telegraph" Todd was one of them, and he was highly
respected at the time (and his grandson, Lawrence Bragg was
Australia's first Nobel Prize winner).
This was necessary, because the scandal is meant as justification of
what I would call 'tax on air', which is apparently planned for the
first world countries, where 'climate' is more or less OK, even it
could be a little warmer in many areas.
The real problem occurs, of course, in much poorer regions, where
pollution and population growth is out of control.
But even if the countries in that region are actually responsible for
what they do, they are far too poor to allow to extract a lot of tax.
So, the industrialized world is blamed for what they are not
responsible and what they could not change efficiently.
The industrial revolution did involve burning a lot of fossil carbon
which has had visible and now well-documented effect on the climate
over the last century. Now that we have got the point where the
cheapest way of generating electric power is with solar cells, and
wind turbines are the second cheapest, we can stop burning fossil
carbon and messing up the climate even more and still manufacture
stuff in huge volumes, and more cheaply and efficiently than we used
to. We haven't actually got to the point where we are burning less
fossil carbon than we did last year, but we are close to it, and China
is making a lot of money out of making remarkably cheap solar cells in
enormous volumes (which is why they can make them cheaply).
The means to justify this bunk is actually a redefinition of the word
'climate', which is now used to describe the mean temperature of the
entire Earth.
Climate got redefined when we could collect enough data around the
world to realise that the weather around the world was connected.
Satellites in orbit looking down at the atmosphere did a much better
job than weather observatories on the ground has done, but ground
based observers had been doing a pretty good job for about a century
before we had satellites to do it better.
This was needed, because otherwise countries in the first world could
rightfully claim, that they were not responisible and had nothing
against warmer 'climate'.
The low lying islands in the Pacific aren't too worried about a warmer
climate in their area, but they are deeply worried about the effects
of a warmer climate on the ice sheets on top of Greenland and West
Antarctica.
Didn't you know, that Antarctica is REALLY cold?
How could any sane person assume, that the Ice-sheet on top of
Antarctica or Greenland would eventually melt?
The floating ice doesn't count, of course, because floating ice does not change sea levels, once it melts.
But sea-levels do actually fall slowly. That can be seen around the
globe at almost any location you like.
For instance: the Sahara desert was once the bottom of an ocean, hence global sea-levels had dropped significantly in respect to former
sea-floor areas.
We can also watch sea-levels dropping in connection with the low level islands in the Pacific, because they are mostly atolls. And an atoll is build from remains of corals and corals are animals, which live in the sea.
Since the corals are not supposed to fly above sea-levels (to build the atolls), the sea-levels have fallen in geological times.
These are are going to slide off and melt over the next few centuries,
and produce about 10 meters of sea level rise, which will submerge a
lot of low lying islands. The Dutch sea defenses are going to need
work too.
Before the ice-sheets of Antarctican and Greenland could eventually
melt, they need to become a lot warmer than their roughly minus 60-# Celsius.

and the useful ones.
Too bad for most theories of mechanics; too
bad for your moronic physics.
Time is a universal _absolute_ parameter.
What you actually mean is 'universal'.
You have, for some odd reasons, the idea that the entire universe must
be universally synchronized.
About space-contraction as length-contraction and
time-dilation together, has that clocks "slow" or
"meet" about differences between "space-contraction-linear"
and "space-contraction-rotational", breaking out the
"space-contraction" as "-linear" and "-rotational"
instead of "length-contraction" and "time-dilation".
Even stranger is, that clocks and time are used interchangeable.
A clock is something that documents the passage of time in the space
where the clock is located. Nobody is going to confuse the ruler used to measure distance with the distance measured.
But a clock is a man-made device, while time is a natural phenomenon
and not supposed to depend on clocks (because nature is not man-made).
Why would anybody think that?
Einstein wrote something like 'time is what clocks say'.
And I had rejected this idea, because it would in effect exchange the
natural phenomenon with the reading of a measuring device.
I regard physical quantities as attributes of some system or object,
while emasuring devices as man-made objects, which belong to the realm
of the observer.

How could any sane person assume, that the Ice-sheet on top of
Antarctica or Greenland would eventually melt?
Nobody does. The assumption is that it would slide off into the ocean
and float until it get closer to the equator.
It's has been doing that for the last few million years. When ice ages
give way to interglacials, it slides off a lot faster. Anthropogenic
global warming hasn't been going on for the sliding-off rate to rise all
that much yet, but it will.
The floating ice doesn't count, of course, because floating ice does
not change sea levels, once it melts.
But ice that was previous sitting on solid earth before it slid down
into the ocean does raise the sea level when it starts floating.
But sea-levels do actually fall slowly. That can be seen around the
globe at almost any location you like.
For instance: the Sahara desert was once the bottom of an ocean, hence
global sea-levels had dropped significantly in respect to former
sea-floor areas.
You need to read up on continental drift.
We can also watch sea-levels dropping in connection with the low level
islands in the Pacific, because they are mostly atolls. And an atoll
is build from remains of corals and corals are animals, which live in
the sea.
Since the corals are not supposed to fly above sea-levels (to build
the atolls), the sea-levels have fallen in geological times.
They fall quite a bit during ice ages, and go up again during
interglacials. The Pacific Rim isn't all that geologically stable, and
places like Iceland and Hawaiian Islands
https://en.wikipedia.org/wiki/Hawaiian_Islands
pop up as volcanoes from time to time. The oldest Hawaiian Island is 28 million years old.
If you want to draw conclusions from Pacific Island histories you do
have to be specif about their geological histories.
These are are going to slide off and melt over the next few
centuries, and produce about 10 meters of sea level rise, which will
submerge a lot of low lying islands. The Dutch sea defenses are going
to need work too.
Before the ice-sheets of Antarctican and Greenland could eventually
melt, they need to become a lot warmer than their roughly minus 60-#
Celsius.
And if the history of ice age to interglacial transitions is anything to
go by, they get warmer by sliding off into the ocean and drifting closer
to the equator. Ice bergs do it all the time and it doesn't take a lot
of global warming to persuade the ice bergs to slide off faster.
James Hansen spelled it out in 2016. It's a minority view, because
nobody know much about the processes happening under the surface of ice sheets, and the fossil carbon extraction industry really doesn't want
anybody to look hard. They do have a lot of political clout.

Antarctica or Greenland would eventually melt?
Nobody does. The assumption is that it would slide off into the ocean
and float until it get closer to the equator.
It's has been doing that for the last few million years. When ice ages
give way to interglacials, it slides off a lot faster. Anthropogenic
global warming hasn't been going on for the sliding-off rate to rise all
that much yet, but it will.
The floating ice doesn't count, of course, because floating ice does
not change sea levels, once it melts.
But ice that was previous sitting on solid earth before it slid down
into the ocean does raise the sea level when it starts floating.
But sea-levels do actually fall slowly. That can be seen around the
globe at almost any location you like.
For instance: the Sahara desert was once the bottom of an ocean, hence
global sea-levels had dropped significantly in respect to former
sea-floor areas.
You need to read up on continental drift.
We can also watch sea-levels dropping in connection with the low level
islands in the Pacific, because they are mostly atolls. And an atoll
is build from remains of corals and corals are animals, which live in
the sea.
Since the corals are not supposed to fly above sea-levels (to build
the atolls), the sea-levels have fallen in geological times.
They fall quite a bit during ice ages, and go up again during
interglacials. The Pacific Rim isn't all that geologically stable, and
places like Iceland and Hawaiian Islands
https://en.wikipedia.org/wiki/Hawaiian_Islands
pop up as volcanoes from time to time. The oldest Hawaiian Island is 28
million years old.
If you want to draw conclusions from Pacific Island histories you do
have to be specif about their geological histories.
These are are going to slide off and melt over the next few
centuries, and produce about 10 meters of sea level rise, which will
submerge a lot of low lying islands. The Dutch sea defenses are going
to need work too.
Before the ice-sheets of Antarctican and Greenland could eventually
melt, they need to become a lot warmer than their roughly minus 60#
Celsius.
And if the history of ice age to interglacial transitions is anything to
go by, they get warmer by sliding off into the ocean and drifting closer
to the equator. Ice bergs do it all the time and it doesn't take a lot
of global warming to persuade the ice bergs to slide off faster.
James Hansen spelled it out in 2016. It's a minority view, because
nobody know much about the processes happening under the surface of ice
sheets, and the fossil carbon extraction industry really doesn't want
anybody to look hard. They do have a lot of political clout.

also not conducive to usual accounts of ecological development.

Shadbolt shares similar sentiments:
Could Einstein's definition of time have been one of the
greatest hindrances to the advancement of human knowledge
that history has ever known?
About Time: Einstein Was Wrong
Discussions about how to define 'time' inevitably become
philosophical debates. As I've noted previously, 'everybody
knows what time is until they try to define it'. For the
framework of this article, let's limit our discussion about
time to looking at Einstein's definition of time in special
relativity and contrasting that with the understanding of
time in quantum mechanics.
In special relativity, Einstein defined time simply as a
measure of how long an event takes, as measured by a clock.
This is a sensible, straightforward measure. For example,
the time it took me to read the previous paragraph, measured
by a stopwatch, was 10 seconds. In special relativity, clocks
are used as an objective standard for measuring the time
intervals of physical processes.
The problem is that this sensible measure of time becomes time
itself.
For example, if an atomic clock is observed to slow down (it
registers fewer oscillations of the caesium atom at a different
altitude), this is not understood as a change in the clock's
operating speed. In relativity, this slowing is interpreted
as a slowing in the rate of time itself.
... this mistaken interpretation commits an error that Sir
Isaac Newton warned us against in his Philosophiae Naturalis
Principia Mathematica.
Newton wrote, 'Relative quantities are not the quantities
themselves whose names they bear, but sensible measures of
them.. and by the names time, space, place, and motion their
sensible measures are to be understood; and the expression
will be unusual if the measured quantities themselves are
meant. ..those violate the accuracy of language, who interpret
these words for the measured quantities.'
Putting this concept into the modern context, even when the
motion of light in a vacuum is used as the standard 'clock' to
measure time, it is still just a physical entity that can be
influenced by other physical processes, known or unknown. This
was Einstein's biggest mistake; he employed a physical process
(the motion of light) to serve as a stand-in for time itself.
In Newton's words, he expressed a sensible measure of time as
time itself.
French philosopher Henri Bergson, a contemporary of Einstein,
disputed relativity's portrayal of time by arguing that there
is a difference between time itself and what clocks display.
Clocks display arbitrary fractions of periodic events such as
the motion of the Sun across the sky (as shown on a sundial),
grains of sand moving through an hourglass, the number of
swings of a pendulum, or the number of oscillations of a
caesium atom (the current standard), but this is not the
physical reality of time itself. The physical reality of time
is the standard against which we can compare these events.

Prove Priestley wrong. Use your best rhetoric to define Time in your own
words.
Rhetoric and words have no physical meaning.

Often it's the only "physical constant" given.
The SI units are much separated from the relevant

Time is a universal parameter of most theories of mechanics,
and the useful ones.
Too bad for most theories of mechanics; too
bad for your moronic physics.
Time is a universal _absolute_ parameter.
What you actually mean is 'universal'.
You have, for some odd reasons, the idea that the entire universe
must be universally synchronized.
About space-contraction as length-contraction and
time-dilation together, has that clocks "slow" or
"meet" about differences between "space-contraction-linear"
and "space-contraction-rotational", breaking out the
"space-contraction" as "-linear" and "-rotational"
instead of "length-contraction" and "time-dilation".
Even stranger is, that clocks and time are used interchangeable.
A clock is something that documents the passage of time in the space
where the clock is located. Nobody is going to confuse the ruler used
to measure distance with the distance measured.
But a clock is a man-made device, while time is a natural phenomenon
and not supposed to depend on clocks (because nature is not man-made).
Why would anybody think that?
Einstein wrote something like 'time is what clocks say'.
And I had rejected this idea, because it would in effect exchange the
natural phenomenon with the reading of a measuring device.
I regard physical quantities as attributes of some system or object,
while measuring devices are man-made objects, which belong to the
realm of the observer.
But clocks can make much more accurate and finer-grained observations
than any merely human observer ever could.
Time is what clocks observe - for us - and in that sense Einstein is absolutely correct. We've still got to read the clock before it's measurements mean anything.

Time is a universal parameter of most theories of mechanics,
and the useful ones.
But time must be a LOCAL parameter ONLY!
It is total bunk to assume, that an 'external' clock would exist,
which synchronizes everything in the universe.
Clocks don't exist to synchronise anything. They can be part of a
local system which synchronises some local action to an event which
has been observed from that location. Granting the bulk of the
universe is expanding away from any given point at a speed which is
increase with time and distance time dilation alone makes the idea of
perfect synchronicity untenable.
If nothing synchronizes remote systems, then how could we rightfully
assume, that remote systems share the same time?
It's a very convenient-a assumption.The big bang theory has the universe starting to expand from a very small point some 13.8 billion years ago,
and what we can see of the observable universe is consistent with that.

As I argued before, that pair of photons /does/ have mass.
Then you are a hopeless case because a photon has mass _zero_ (in the
Standard Model of particle physics).
That is how it not only can, but why (according to special
relativity) it
MUST, propagate at c. We can see that as follows:
The energy dispersion relation for a photon is E = raA -e(K), and one
finds
-e(K) = k c, so E = raA k c = raA/(2-C) (2-C/++) c = (raA/++) c. But
p = raA/++,
so for a photon
E = p c.
The energy-momentum relation for a free particle in Minkowski space is >>>>
E^2 = m^2 c^4 + p^2 c^2 <==> m = 1/c reU(E^2 - p^2 c^2)
so
E = p c ==> m = 0. reA
But even if it would /not/ have mass.
It does not.
The source of gravity
_gravitation_
is
not mass, but energy-momentum (the energy-momentum tensor T)
(in general relativity).
Correct.
A photon passing by the sun is attracted to it.
No, it follows the curvature of spacetime.
To conserve
momentum, the sun must also be attracted by the photon!
/Ex falso quodlibet./
F'up2 .relativity
Ah, yet _ex falso quodlibet_ is the compounding of fallacy
and admission of truth's defeat, the conscientious logician
must instead demand _ex falso nihilum_, since _ex falso falsum_.
"Energy" is never "pure energy", always in the quantities
in the forms.
The, "indeterminate forms", vis-a-vis, the undefined,
may make surely for the, "determinate forms",
in the defined.
Solar sails work. If one suggests that it's "ionic wind"
others have that it's light plainly.
Actually, a photon follows about _half_ the curvature of
spacetime, which was enough to improve the computation
of the precession of Mercury.

Two wrongs don't make a right.
One may observe, for example, the crescent Moon:
a the light that limns its outline, as another
example of light getting around, and its constant
flux in the cosmic clock-works. Much like Arago
spot, it shows that optical light is special.
Then, there's a full lunar Eclipse in N. America on
about March 6 in a few weeks, it's an aspect of
syzygy in the sky survey available to all since antiquity
that interested viewers may study through totality.
