If one uses the "classical radius of the electron" and the known total angular momentum of the electron, it is easy to calculate that a point on the equator of the electron is moving at about 137 times the speed of light(adsbygoogle = window.adsbygoogle || []).push({});

How is this 137 arrived at ?

Any formula or method to get to this no. ?
