In what book do I find the theory behind this qs.? The qs is: http://grephysics.net/ans/9277/50
Re: GR9277 #50
Well any qm textbook would demobstrate this fact basically.
Anyway qm is also known as matrix mechanics for a reason. The question is basically asking when does the order of observations not matter i.e. when is AB\psi=BA\psi for ALL \psi?

In fact you don't even need a quantum mechanics text. All you need is a linear algebra text.
