[Fis] Probability Amplitudes in Macroscopic Processes

2014-01-22 Thread Joseph Brenner
Dear Lars-Göran, Andrei and Hans, As you (I hope) have seen, I am trying to see how the evolution of macroscopic processes can be described in terms of changing probabilities, and I am encouraged to believe this is possible. If you allow the extension from QM, all of the following would seem

Let me clarify one point: by saying that probability amplitudes represent real physical features I reject the instrumentalist idea that they are mere calculational devices. But of course, the probability amplitude is no observable. But there is no need to claim that only observables have any
