Hi Richard Ruquist Read what I said below again. I never said that the quantum world is physical, quite the reverse.
Not to worry, I have made similar mistakes, especially my inverted interpretation of the gini index.

Roger, Quantum mechanics is not physical nor is string theory. How the physical world comes from the quantum world is a matter of conjecture called interpretations.
