- Paul, I'm not a quantum mechanic (I wish most of the time I was one
- with a 50% polarization :-), but I don't think the projection postulate
- necessarily requires this collapse thing. I think it states that
- after an experimentation the system will be in state given by: P_a|H> = c<H|H>
- or something like that. I don't see anything collapsing here. Then there
- is the statistical operator that takes care of everything that one can say
- about the experiment. I don't see anything about linear propagation of wave
- function etc either. Are you questioning whether |H|^2 is really a probability ?

- P.S: A good book for the layman is by Sidney sudbery called QM and the particles
- of nature.
