Tim:

An interesting non-math book to read on the subject is, Karl Popper "Quantum
Theory and The Schism in Physics".  Another is,  J.T. Fraser, "The Genesis
and Evolution of Time: A Critique of Interpretation in Physics".  I
apologize if this last is dated.  It and Popper come from a former life (and
library) of mine.

If one is a dualist and thinks of the real in terms of the sensible world
then both Relativity theory and Quantum mechanics most definitely deal with
the unreal and the not sensible.  One, the large to the point of infinity,
the other the small to the point of infinity.

The observable fact that they (Quantum and Relativity theory) yield
reproducible and predictable results is beneficial but does not make either
worldly.

Perhaps they are both part of "Absolute Rhythm".  Something that is
abstract, unreal yet beneficial, reproducible and predictable.
