- My questions seem to have drowned in Sarfatti noise. Scott, you had
- said a good quantum no. for a system is that whose operator
- commutes with the Hamiltonian for that system. But you left open the
- question whether the position operator can ever commute with a
- Hamiltonian and if it does, how one can interpret the delta function
- eigenstate of the position operator. This was in context of Liboff's
- statement that the measurement of a varible leaves the system in an
- eigenstate of that system. My other question about transition
- lifetime from the first excited state in a 1-D infinite well has
- also
- gone unanswered. I do wish Sarfatti would rather answer such
- questions
- than adding all that noise.
