Re: Electron size, shape and spin.Confusion and conflicts with Einstein's 1905 SR.

I forgot to add that, as E = e^2/R (esu units), in quantum physics the
Classical Electron Radius of about 10^-15 m is used, IN ORDER TO obtain
0.511 MeV.
Because of the problems of INFINITIES, in applied QFT and QED, this is
the radius used for calculations, EVEN WHEN the theory is based on the
electron being a POINT-LIKE PARTICLE. If R=0 was used, it would give
INFINITY ENERGY.
So, the geniuses since Feynman RENORMALIZED the QED theory by just
PLANTING the 0.511 MeV rest energy in calculations. No sense? But it
works, Feynman said.
SHUT UP AND CALCULATE!
Physics is a farce when dealing with ANY CRAP derived from relativity.
