Does the electron really spin 720 degrees?

In summary: I don't know, some sort of symmetry or law that governs the behavior of particles?In summary, I don't think there is any real meaning to a point particle "spinning", that's an intrinsically macroscopic concept. A better way to think of it is that if you were to rotate the electron (or any fermion having spin 1/2) then it is symmetrical under 4π (720deg) rotation not 2π (360deg) as would be the case with the integer spin particles (e.g. photon).

try a 'field' :)
