  • Two things are infinite

    What folks chalk up to physicists:

    |Two things are infinite: the universe and human stupidity;
    |and I'm not sure about the universe!

    . What physicists actually put out:

    |There are two things which are infinite: The first, for a
    |classical black hole, the first is the time, that it takes
    |for anything to get to the blackhole surface, and the second
    |is the amount of information that you can hide in this thin
    |sedimentary structure that just approaches the horizon.

    The Dirac delta or unit impulse function is quite usual
    in derivations in physics: infinitely tall, infinitesimally
    wide, area one, everyone's first and usually only
    not-a-real-function with real analytical character.

    The most central and primary not-a-real-function with
    real analytical character is the natural/unit equivalency function.
