Physics has not been compatible with classical physics for over a hundred years.
So I am learning, js1138. Still if I'm understanding QM correctly, it appears that we humans are "quantum systems," too; and as such, part of and coextensive with the universal quantum system. If humans can reshape their world, make great scientific discoveries, etc., etc., then there has to be something that can account for such abilities. It seems to me that would have to be consciousness, mind. (Walker does an elaborate and extensive demonstration of the mind/brain as a quantum system itself. He actually derives an elegant equation to show how the two "connect." If my HTML were up to rendering scientific notation, I'd post that equation here, for your delectation.) And even if the Copenhagen School "doesn't want to go there," it seems that, inevitably, they must -- if they want to understand the implications of their own theory.
