The
Physics of Quantum Mechanics |

An
introduction |

physical implications of quantum mechanics by explaining how quantum systems

evolve in time, and showing the close parallels between quantum and classical

dynamics.

The text starts by introducing probability amplitudes and stresses

that the use of amplitudes rather than probabilities is what makes quantum

mechanics unique. The physical significance of operators is more clearly

explained than in conventional texts, and Dirac notation is used from the

outset, so students learn early on that they are free to choose the most

convenient representation for a particular problem. The mathematical

development of the subject is more self-contained and rigorous than in

traditional texts because most eigenvalue problems are solved by operator

methods.

This edition is designed to accompany a course of lectures at Oxford

University.
