    One of my young engineers just got the first unit of a thing he
    designed. He was all cautious about bringing it up a step at a time,
    so I just pulled rank and switched it on in self-trigger mode. It
    works.

    It's an 8-channel high voltage pulse generator. We're not sure what
    it's used for and the customer won't tell.

    You have to pulse the water in just the right sequence to use it as a
    fuel you see:

    Bosses do that kind of thing. It does blow up quite a few components.

    I wish there were more clients looking for designs where the designer
    gets to keep what it does a secret, also, that would make life easier.

    Could be for the timing capacitors in a fusion bomb. I really wouldn't

    I've done timing to fire implosion fission bombs, and this doesn't
    look to be one of those.

    Some of the things that could be really fun aren't, because the good

    One of my son-in-laws has a PhD in engineering mechanics and works for
    a big lab that blows things up. He says it's not much fun because the
    booms happen miles away and all he gets is data.

    We did the master timing system and the beam modulators for NIF, the
    fusion laser in Livermore. The fusion energy yield is about the energy
    in a jelly donut.

    After decades, they finally got the fusion yield, energy out over UV
    light in, above unity.

    "Fusion" bombs are wrapped around a fission bomb, typically an implosion device. I haven't clue what the fusible layer is - Wikipedia says
    lithium deutride - and a tamper layer is wrapped around that. If the
    tamper layer is made of uranium you get a very dirty
    fission-fusion-fission bomb. The only interesting timing involved is in
    getting the shell of explosives to go off all at once so that you get
    your symmetrical implosion to compress the inner core of plutonium.

    The fisson bomb is different from an implosion fission bomb, but only in structure - the timing problem is exactly the same.

    A petard was a very small canon or mortar used for blowing down doors

    It may be one of the many idioms that Shakespeare invented (and he
    invented a lot), but the weapon was invented in 1579 when Shakespeare
    was 15, so he could well have picked up the phrase from some of his contemporaries.

    You see, for me the word "petard" is very similar to the Spanish

    The wikipedia doesn't explain why it was that dangerous. The Spanish

    It comes from French. It literally means "farter".

    It may be one of the many idioms that Shakespeare invented (and he
    invented a lot), but the weapon was invented in 1579 when Shakespeare
    was 15, so he could well have picked up the phrase from some of his
    contemporaries.

    Wow, thanks, I always wondered where the expression came from.

    You see, for me the word "petard" is very similar to the Spanish
    "petardo", a firecracker.


    The wikipedia doesn't explain why it was that dangerous. The Spanish article on it is much shorter, but the explanation on how it was
    prepared is more detailed.



    It comes from French. It literally means "farter".

    In French, "Chat GPT" becomes "Cat, I have farted".
