Quantum mechanics allows you to determine their expectation values. The issue is whether there is a mathematical model. I think mathematical model is possible. But such a model that considers all interactions is not solvable. > > bill peter ihnp4!lanl!wkp > > "Plasma physicist: a physicist standing too near a nuclear event." *** REPLACE THIS LINE WITH YOUR MESSAGE *** -- Yosi Hoshen, AT&T Bell Laboratories Naperville, Illinois, Mail: ihnp4!ihu1m!jho
