Charge distribution inside the electron ?

  1. Jun 13, 2012 #1
    The page here mentions about the charge distribution inside the electron but I do not know how this assumption is made. It will be nice if some one can help me out with this.

    This assumption is made out of the author's fancy.
    He visibly does not have a clue about quantum physics and how fundamentally different it is from classical mechanics.
    Quantum physics defines the electron as a fundamental particle. Thus it has no "internal structure" except for the cloudiness of its presence which, when measured below some resolution, mixes with the virtual electron/positon pairs of the quantum void fluctuations so that it can no more be distinguished from these fluctuations.
    So this is quite a complex story, however the idea is that electrons have no parts of
    any nature different from themselves: cutting it in 2 probably gives back one electron on one side and possibly one or more electron/positon pairs on the other.

    In particular, the spin is a fundamental quantity in quantum theory, and the one of the electron is rigorously indivisible.
