Presents a guide to the basics of quantum mechanics and measurement.

This landmark book is now reissued in a new edition that has been vastly rewritten and updated to respond to recent Kantian literature.

This is one of the most important books on quantum mechanics to have appeared in recent years. It offers a dramatically new interpretation that resolves puzzles and paradoxes associated with the measurement problem and the behavior of coupled systems. A crucial feature of this interpretation is that a quantum mechanical measurement can be certain to have a particular outcome even when the observed system fails to have the property corresponding to that outcome just prior to the measurement interaction.
