questions about Pauli matrices 
why do they need to be Hermitian, what are they trying to measure and why do they need to
satisfy that those matrices squared equals the identity matrices.
Hi :)
I have several questions about the Pauli matrices,
I have seen them when the lecturer showed us SternGerlach experiment
, and we did some really weird assumptions on what we think they should be.
1 why did we assume that all of those matrices should satisfy
σ^{2} = I (the identity matrices)
2 why do they have to be Hermitian?
3 what they are trying to measure? (when we insert < for example, we get <, why is that? )
thanks for helping !!!
