I need a hint!

  1. Dec 9, 2004 #1
    Can anyone give me some hints? I need to prove that all spinors to a spin-1/2 particle are eigenvectors to [tex]\hat S^2[/tex]!

    What is spin???It's a weird form of angular momentum.
    Use the theory of angular momentum to show that S_{z} and S^{2} commute then apply a monstruously important theorem of functional analysis to find your result.

    That´s right. Sometimes a problem is very easy. Good Luck Daniel!
