Quantum Mechanics

Julian Schwinger, who shared the 1965 Nobel Prize for Physics for his pioneering work on quantum electrodynamics, had a considerable influence on the conceptual development of modern quantum field theory. He was a brilliant teacher and researcher, and this book demonstrates his outstanding ability to expose a difficult subject in a clear and concise style. In this book the whole of quantum kinematics and the underlying quantum action principle are derived through a systematic analysis of experimental phenomena. A unique legacy, these lecture notes of the Schwinger course held at the University of California at Los Angeles were carefully edited by his former collaborator Berthold-Georg Englert. They constitute a textbook on quantum mechanics and an indispensable source of reference.
