William Lane Craig once recommended physicist Nick Herbert’s book, Quantum Reality: Beyond the New Physics, as a great introduction to quantum theory.  I picked up a copy to tackle this strange and oft-misunderstood topic.

Quantum mechanics is not for the faint-hearted.  It is difficult to grasp.  Even after reading this book I still can’t say I understand quantum mechanics well enough to explain it with confidence, but at least now I have a better understanding of what I don’t understand.  Apparently I’m in good company.  Richard Feynman once said, “I think it is safe to say that no one understands quantum mechanics.”

One thing I did glean from this book is what the debate is all about.  It’s not about the quantum facts.  We know the facts well.  And it’s not even so much over quantum theory (the mathematics used to describe the quantum facts).  Rather, the debate is about the physical interpretation of quantum theory.  What is the reality of the quantum world?
