In this wikipedia article is written about Electron's spin.
it was produced by the self-rotation of the electron. When Pauli heard about the idea, he criticized it severely, noting that the electron's hypothetical surface would have to be moving faster than the speed of light in order for it to rotate quickly enough to produce the necessary angular momentum.
I am wondering how they get this statement
electron's hypothetical surface would have to be moving faster than the speed of light
I would like to get real numeric value of electron angular momentum and check this statement :)
And my question is: What is the numerical value of Electron's Angular momentum in SI $\Large\frac{kg*m^2}{s}$?
If I know this value, I can calculate rotation frequency from formula $L=I\omega$ where L - angular momentum and I - moment of inertia. and if I know frequency $\omega$, I can find a speed if I assume some electron radius like "classical electron radius" or something else.
