“Some physicists still find quantum mechanics unpalatable, if not unbelievable, because of what it implies about the world beyond our senses.  The theory’s mathematics is simple enough to be taught to undergraduates, but the physical implications of that mathematics give rise to deep philosophical questions that remain unresolved.  Quantum mechanics fundamentally concerns the way in which we observers connect to the universe we observe.  The theory implies that when we measure particles and atoms, at least one of two long-held physical principles is untenable.  Distant events do not affect each other, and properties we wish to observe exist before our measurements.  One of these, locality or realism, must be fundamentally incorrect.”
