[OT] Re: Primes and I
- Yes the nipping in and out of 3-d idea was a bit corny.
But I want to reinforce what Jud said about absolute
indistinguishability in physics. In quantum mechanics
you have a wavefunction for every electron that you
happen to think is in a box, and then have to antisymmetrize
to take account of their indistinguishability.
But in the full quantum theory there is a _single_
anticommuting field whose potentialities describe
every electron and positron in the universe. If anyone asks
"which electron was that?" there is _no_ possible answer.
Also there no answer to the question: "how many electrons
in this box"; only the difference #electrons - #positrons
