If that is the case then realism is correct and, to be consistent with experimental results, either determinism or locality or both must be wrong. You just can't have realism and localityand determinism, you've got to abandon at least one of those three things.* * >OR, as in the Stern-Gerlach experiment, it's not in any of the states of > the superposition before measurement!* > *Yes It could be that it was not in any one particular state before a measurement in which case realism would be wrong, or it could be that it was in all possible states before a measurement in which case realism is also wrong. For realism to be correct it would have to be in one and only one definite state before a measurement was made. * > *he's referring to results of Bell experiments, which ostensibly deny > realism.* *The falsification of Bell's Inequality does not mean realism must be wrong, it means that realism might be wrong, and if it's right then determinism or locality or both must be wrong. * > *> Copenhagen doesn't explain the collapse of the wf as a dynamical event. > I view it as a bookkeeping device* > *Yes, and some people, perhaps even most people, don't even try to explain the ambiguities in Quantum Mechanics and are content with the "Shut Up And Calculate" philosophy** (a.k.a. the Copenhagen interpretation) ;** and that's fine if you're an engineer and are only interested in making sure you get the right reading on your voltmeter. Personally I'd like a little more but there is no disputing matters of taste. * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis> *dts * > -- You received this message because you are subscribed to the Google Groups "Everything List" group.
