I don't know how to derive fermions and bosons from nothing but arithmetic but you can
do the next best thing. If the Schrodinger wave function for a particle is a odd
function, that is F(x) = -F(-x), then it's a fermion and the probability of 2 fermions
occupying the same quantum state is zero, in other words it obeys the Pauli Exclusion
Principle and is the reason that the ground beneath your feet, which is made of
fermions, is solid and you don't sink to the center of the Earth.
If the Schrodinger wave function for a particle is a even function, that is F(x) =
F(-x), then it's a boson and it can ignore the Pauli Exclusion Principle and is the
reason light rays, made of bosons, don't scramble each other when they collide at right
angles, light particles can occupy the same quantum state and thus can pass through each
other and be completely unaffected; it's the reason the light rays that enter our eye
are not a hopeless chaotic jumble of information randomized by a astronomical large
number of collisions with other photons.
Yep, I knew that. I thought for a moment that Bruno claimed to derive something like that
from comp, but it turns out that all he claims is that if comp is the theory-of-eveything
then it must predict everything.
