This text builds a solid introduction to the concepts and techniques of quantum mechanics in settings where the phenomena treated are sufficiently simple that the student does not face two fundamental difficulties simultaneously: viz, that of learning quantum mechanics and that of learning how to assess the validity of models or the reliability of approximations. The treatment thus confines itself to systems that can either be solved exactly or be handled by well-controlled, plausible approximations. With few exceptions, this means systems with a small number of degrees of freedom. The exceptions are a first pass at many-electron atoms, the electromagnetic field, and the Dirac equation. (The inclusion of these last two topics reflects the now widely-held belief that every physicist should have at least a nodding acquaintance with these cornerstones of modern physics.) Born in Vienna, Kurt Gottfried emigrated to Canada in 1939 and received his Ph.D. in theoretical physics from MIT in 1955. He is professor of physics at Cornell University, and had previously been at Harvard University, the Massachusetts Institute of Technology, and at CERN in Geneva. He is the co-author of Concepts of Particle Physics (with V.F. Weisskopf), and of The Fallacy of Star Wars and Crisis, Stability, and Nuclear War. Gottfried has an active interest in arms control and human rights and is a founder and currently the Chair of the Union of Concerned Scientists.

This book contains discussions of radiation theory, quantum statistics and the many-body problem, and more advanced topics in collision theory. It is intended as a text for a first-year graduate quantum mechanics course.

The second volume of this authoritative work traces the material outlined in the first, but in far greater detail and with a much higher degree of sophistication. The authors begin with the theory of the electromagnetic interaction, and then consider hadronic structure, exploring the accuracy of the quark model by examining the excited states of baryons and mesons. They introduce the color variable as a prelude to the development of quantum chromodynamics, the theory of the strong interaction, and go on to discuss the electroweak interaction--the broken symmetry of which they explain by the Higgs mechanism--and conclude with a consideration of grand unification theories.

This book is the most complete collection of John S Bell's research papers, review articles and lecture notes on the foundations of quantum mechanics. Some of this material has hitherto been difficult to access. The book also appears in a paperback edition, aimed at students and young researchers. This volume will be very useful to researchers in the foundations and applications of quantum mechanics.

This classic text provides a comprehensive exposition of the concepts and techniques of quantum mechanics. The phenomena treated are sufficiently simple to allow the student to readily assess the validity of the models so that attention is not deflected from the heart of the subject. To that end, the book concentrates on systems that can either be solved exactly or be handled by well-controlled, plausible approximations. With few exceptions, this means systems with a small number of degrees of freedom. The exceptions are manya "electron atoms, the electromagnetic field and the Dirac equation. The inclusion of the last two topics reflects the belief that every physicist should now have some knowledge of these cornerstones of modern physics.

This new edition has been completely revised and rewritten throughout, but retains the clarity and readability of the first edition.

Born in Vienna, Kurt Gottfried emigrated to Canada in 1939 and received his Ph.D. in theoretical physics from the Massachusetts Institute of Technology in 1955. He is a professor emeritus of physics at Cornell University, and had previously been at Harvard University and at CERN in Geneva, Switzerland. He is the coauthor of Concepts of Particle Physics (with V.F. Weisskopf) and of Crisis Stability and Nuclear War. Gottfried has done research in both nuclear and particle physics; he has an active interest in arms control and human rights and is a founder and currently the Chair of the Union of Concerned Scientists.

Tung-Mow Yan, originally from Taiwan, received his Ph.D. in theoretical physics from Harvard University in 1968. He has been a member of the Cornell University faculty since 1970 afterspending two years as a research associate at the Stanford Linear Accelerator Center. He has conducted research in many areas of elementary particle physics.

A reprint series which has come into being as a direct result of public demand for the individual volumes in this program. An attractive design and and trim-size for the 'ABC' titles, giving the series a striking appearance, while lending the individual titles unifying identity as part of the 'Advanced Book Classics Program.'

This authoritative work enhances the material outlined in the first volume of Concepts of Particle Physics, presenting it in far greater detail and with a higher degree of sophistication. The authors, both eminent physicists, provide an in-depth discussion of the electromagnetic interaction, explore the accuracy of the quark model by examining the excited states of baryons and mesons, and consider many other topics.

Scientists debate the role of scientific research in the military-industrial complex and consider the complicity of academic science in American wars. On March 4, 1969, MIT faculty and students joined together for an extraordinary day of protest. Growing out of the MIT community's anguish over the Vietnam War and concern over the perceived complicity of academic science with the American war machine, the events of March 4 and the days following were a "positive protest"-a forum not only for addressing political and moral priorities but also for mapping out a course of action. Soon afterward, some of the participants founded the Union of Concerned Scientists. This book documents the March 4 protest with transcripts of talks and panel discussions. Speakers included Noam Chomsky, Howard Zinn, Lionel Trilling, and Nobel Laureate George Wald, whose memorable speech, "A Generation in Search of a Future," was widely circulated. Topics of discussion ranged from general considerations of the intellectuals' political responsibility to specific comments on the Vietnam War and nuclear disarmament. This fiftieth anniversary edition adds a foreword by Kurt Gottfried, a physicist, participant in the March 4 protest, and cofounder of the Union of Concerned Scientists. He writes, forcefully and hopefully, "Fifty years ago, a remarkable awakening was occurring among American scientists about their role in society. This volume offers a fascinating snapshot of that moment on March 4, 1969, and the activities and discussions collected here remain relevant and resonant today." In an era when many politicians routinely devalue science, we can take inspiration from the March 4 protests.
