should be more massive than an electron... and there are certain to be
other errors of haste.
BTW in one Physics model the proton, with 3 constituent quarks, has 3
times the mass of up and down quarks (the up and down quark constituent
masses being equal), and the proton/electron mass ratio is calculated to be:
3 x 2 pi^5 = 6 pi^5 = 1,836.12
which is fairly nifty if one might wish to add some kind of
"dimensional" significance to the fifth power.
