    *Can't we assume the electrons which I think are identical, all

*On an unrelated issue, I recall your mention that wrt the S. Cat thought experiment, there is no* *operator which has Alive and Dead as eigenvalues. IMO, this implies that the S.

I then realized that the P * *operator for momentum must have a real value for its eigenvalues since it's Hermitian, BUT*
*how can a real value represent momentum, which is a vector?  TY, AG*
*The eigenvector would be momentum.
