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.
