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.

'In a very careful, subtle, and deeply original piece of work, Healey has … achieved something no one else has been able to do in the sixty-year history of the discussion of quantum mechanics.'

Howard Stein - University of Chicago

'Very well-informed and astute.'
