Physicists *frequently* talk as if QM was defined by God writing its formulation into stone in front of Moses, like religious fundamentalists talk. There are measure/probability theoretic formulations of QM that do not come from any "density matrix" or Hilbert space but from their measure/probability spaces. @philipthift -- You received this message because you are subscribed to the Google Groups "Everything List" group.
