It is a fundamental quantum doctrine that a measurement does not, in general, reveal a pre-existing value of the measured property. On the contrary, … - Nathaniel David Mermin

It once made sense to exclude the scientist from scientific explanations of the physical world. This warded off superstitious, animistic, or religious explanations. But without endorsing superstition, animism, or religion, today it makes sense to insist that the scientist should not be excluded from a philosophical understanding of the nature of scientific explanation. Why shouldn't such an understanding involve the explainer, as well as the explained?

An extrapolation of its present rate of growth reveals that in the not too distant future Physical Review will fill bookshelves at a speed exceeding that of light. This is not forbidden by general relativity since no information is being conveyed.

I would like to describe an attitude toward quantum mechanics which, whether or not it clarifies the interpretational problems that continue to plague the subject, at least sets them in a rather different perspective. This point of view alters somewhat the language used to address these issues—a glossary is provided in Appendix C—and it may offer a less perplexing basis for teaching quantum mechanics or explaining it to nonspecialists. It is based on one fundamental insight, perhaps best introduced by an analogy.
My complete answer to the late 19th century question "what is electrodynamics trying to tell us" would simply be this:<p>Fields in empty space have physical reality; the medium that supports them does not.<p>Having thus removed the mystery from electrodynamics, let me immediately do the same for quantum mechanics:<p>Correlations have physical reality; that which they correlate does not.
