Mathematically, a state in QM is a ray on the Hilbert space. But:
1) How would you define "state" from a physical point of view? I know a lot of examples but not a general definition.
2) Given a specific quantum system, to find all the states and so the Hilbert space, all I have to do is to solve the Schrödinger equation (when this is possible)?
