For almost two decades, Sidney Coleman has been giving review lectures on frontier topics in theoretical high-energy physics at the International School of Subnuclear Physics held each year at Erice, Sicily. This volume is a collection of some of the best of these lectures. To this day they have few rivals for clarity of exposition and depth of insight. Although very popular when first published, many of the lectures have been difficult to obtain recently. Graduate students and professionals in high-energy physics will welcome this collection by a master of the field.

This classic, the first of three volumes, presents techniques that emphasize the unity of high-energy particle physics with electrodynamics, gravitational theory, and many-particle cooperative phenomena. What emerges is a theory intermediate in position between operator field theory and S-matrix theory, which rejects the dogmas of each and gains thereby a calculational ease and intuitiveness that make it a worthy contender to displace the earlier formulations.

This classic book (volume two of three volumes) is almost exclusively concerned with quantum electrodynamics. As such, it is retrospective in its subject matter. The topics discussed range from anomalous magnetic moments and vacuum polarization, in a variety of applications, to the energy level displacements in hydrogenic atoms, with occasional excursions into nuclear and high-energy physics. Based as it is upon the conceptually and computationally simple foundations of source theory, little in the way of formal mathematical apparatus is required, and thus most of the book is devoted to the working out of physical problems.

"Knowledge of the renormalization group and field theory is a key part of physics, and is essential in condensed matter and particle physics. Written for advanced undergraduate and beginning graduate students, this textbook provides a concise introduction to this subject. The textbook deals directly with the loop-expansion of the free-energy, also known as the background field method. This is a powerful method, especially when dealing with symmetries, and statistical mechanics. In focussing on free-energy, the author avoids long developments on field theory techniques. The necessity of renormalization then follows"--

As relevant today as it was when it was first published 20 years ago, this book is a classic in the field. Nowhere else can you find more complete coverage of radiation and scattering of waves. The chapter: Asympotic Evaluation of Integrals is considered the definitive source for asympotic techniques. This book is essential reading for engineers, physicists and others involved in the fields of electromagnetics and acoustics. It is also an indispensable reference for advanced engineering courses.

According to the author of this concise, high-level study, physicists often shy away from group theory, perhaps because they are unsure which parts of the subject belong to the physicist and which belong to the mathematician. However, it is possible for physicists to understand and use many techniques which have a group theoretical basis without necessarily understanding all of group theory. This book is designed to familiarize physicists with those techniques. Specifically, the author aims to show how the well-known methods of angular momentum algebra can be extended to treat other Lie groups, with examples illustrating the application of the method. Chapters cover such topics as a simple example of isospin; the group SU3 and its application to elementary particles; the three-dimensional harmonic oscillator; algebras of operators which change the number of particles; permutations; bookkeeping and Young diagrams; and the groups SU4, SU6, and SU12, an introduction to groups of higher rank. Four appendices provide additional valuable data.

The New York Times ’s James Glanz has called Steven Weinberg “perhaps the world’s most authoritative proponent of the idea that physics is hurtling toward a ‘final theory,’ a complete explanation of nature’s particles and forces that will endure as the bedrock of all science forevermore. He is also a powerful writer of prose that can illuminate—and sting... He recently received the Lewis Thomas Prize, awarded to the researcher who best embodies ‘the scientist as poet.’” Both the brilliant scientist and the provocative writer are fully present in this book as Weinberg pursues his principal passions, theoretical physics and a deeper understanding of the culture, philosophy, history, and politics of science.Each of these essays, which span fifteen years, struggles in one way or another with the necessity of facing up to the discovery that the laws of nature are impersonal, with no hint of a special status for human beings. Defending the spirit of science against its cultural adversaries, these essays express a viewpoint that is reductionist, realist, and devoutly secular. Each is preceded by a new introduction that explains its provenance and, if necessary, brings it up to date. Together, they afford the general reader the unique pleasure of experiencing the superb sense, understanding, and knowledge of one of the most interesting and forceful scientific minds of our era.

Flying Saucers and Science is a comprehensive look at the scientific data on the flying saucer phenomenon. Nuclear physicist and lecturer Stanton T. Friedman has distilled more than 40 years of research on UFOs, and shares his work on a wide variety of classified advanced nuclear and space systems. He answers a number of physics questions in layman's terms, and establishes that travel to nearby stars is within reach, without violating the laws of physics. This book presents intriguing data from a number of large-scale scientific UFO studies that almost no one has discussed in detail. It deals with ''why'' questions, such as reasons for a cover-up, reasons for aliens to come to Earth, and reasons for them not landing on the White House lawn. Friedman unveils the SETI program and details the antipathy of science-fiction writers to UFOs. He also reviews false notions about those who believe in alien visitors and the adequacy of coverage by media and the scientific community. After reading Flying Saucers and Science, you will never think the same way about UFOs again.

The first in a series of superb science fiction. Alpha is, aside from the first letter of the Greek alphabet, a term that denotes excellence and primacy in a variety of disciplines: in nuclear physics, for example, it is the name of a particle of unusually large mass and charge. It seemed a useful label to attach to this volume, the first of an intended series of collections of science fiction stories. The Alpha series of anthologies will center on no particular theme except that of literary quality. The presence in any one volume of a cluster of stories bearing other thematic resemblance-as in this volume, where there are four or five time-travel stories-will be purely coincidental. I propose to cull the files of the science fiction magazines for stories that an educated and sophisticated reader will find stimulating, and to assemble them in books of roughly equal size that will appear once a year over the next few years. Some of the stories will be fifteen or twenty years old and richly in need of restoration to print. Others will be quite recent: the literary level of the science fiction short story has undergone an extraordinary transformation in the past few years, a fact that demands recognition here. Appropriately enough, this first volume of the ALPHA series covers a roster of writers from A to Z. Specifically, Aldiss to Zelazny-although this coincidence in alphabet is merely incidental to the fact that both these gentlemen, and the several others represented in this anthology, all write superb science fiction. Two criteria were used in the selecting of these stories-literary merit and importance to the genre. The result is that the variety of subjects is matched only by the richness and diversity of their handling-brilliant, frightening, clever, bizarre, powerful, witty, funny-and several steps in-between. So much for policy. The nine volumes of this series provide an exciting cumulative view of a field in which some of the most vigorous and inventive fiction of our times has been produced. Simply put, here is the best science fiction from the best science fiction writers.

Unlike most textbooks on electromagnetic theory, which treat electricity, magnetism, Coulomb's law and Faraday's law as almost independent subjects within the framework of the theory, this well-written text takes a relativistic point of view in which electric and magnetic fields are really different aspects of the same physical quantity. Suitable for advanced undergraduates and graduate students, this volume offers a superb exposition of the essential unity of electromagnetism in its natural , relativistic framework while demonstrating the powerful constraint of relativistic invariance. It will be seen that all electromagnetism follows from electrostatics and from the requirement for the simplest laws allowable under the relativistic constraint. By means of these insights, the author hopes to encourage students to think about theories as yet undeveloped and to see this model as useful in other areas of physics. After an introductory chapter establishing the mathematical background of the subject and a survey of some new mathematical ideas, the author reviews the principles of electrostatics. He then introduces Einstein's special theory of relativity and applies it throughout the rest of the book. Topics treated range from Gauss's theorem, Coulomb's law, the Faraday effect and Fresnel's equations to multiple expansion of the radiation field , interference and diffraction, waveguides and cavities and electric and magnetic susceptibility. Carefully selected problems at the end of each chapter invite readers to test their grasp of the material. Professor Schwartz received his Ph.D. from Columbia University and has taught physics there and at Stanford University. He is perhaps best known for his experimental research in the field of high-energy physics and was a co-discoverer of the muon-type neutrino in 1962. He shared the 1988 Nobel Prize in Physics with Leon M. Lederman and Jack Steinberger.

This is a collection of essays by the leaders of what has been called the most important development in the theory of knowledge since the 18th century: namely evolutionary epistemology. The motif for this volume is struck in Bartley's opening chapter: Philosophy of biology versus Philosophy of Physics and is continued in Sir Karl Popper's Darwin lecture, Donald T. Campbell's application of Darwinian theory to creative thought processes, and in the debate over the theories of Campbell and Gunter Wachtershauser on the origins of vision.

In this splendidly lucid and profusely illustrated book, a Nobel laureate relates the fascinating story of Einstein, the general and special theories of relativity, and the scientists before and since who influenced relativity's genesis and development. Eschewing technical terms in favor of ordinary language, the book offers a perfect introduction to relativity for readers without specialized knowledge of mathematics and science. The author follows Einstein's own dictum to make explanations "as simple as possible, but not more so." His periodic use of equations as points of clarification involve nothing more than simple algebra; these can be disregarded by math-averse readers. Dr. Schwinger begins with a discussion of the conflict between two principles of electromagnetic theory that are irreconcilable in Newtonian physics, and how Einstein's attempts to resolve this conflict led to the theory of relativity. Readers learn about the meaning of time and the paradoxes of space travel at speeds close to that of light, following the development of Einstein's relativistic thought and his epochal perception that E=mc 2. Further chapters examine gravity and its effect on light; non-Euclidean geometry and the curving of space-time; and the impact of radio astronomy and space-age discoveries upon Einstein's model of the universe. Amusing quotes, suppositions, and illustrative fictions — along with numerous sidebars and boxes explaining physical principles, anomalies, events, and inventions — enhance this accessible introduction, and provide stimulating food for thought.

This authoritative text provides a lively, thought-provoking and informative summary of neutrino astrophysics. Neutrino astronomy is being revolutionized by the availability of new observational facilities. Theoretical work in astrophysics and in particle physics in increasing rapidly. The subject of solar neutrinos has many seemingly independent aspects, both in its theoretical basis (involving nuclear, atomic, and particle physics, geochemistry, and astronomy). For many physicists, solar neutrinos constitute the low-energy frontier of high-energy physics. Results from all these disciplines are combined here, providing a timely and unified discussion of the field. Each chapter begins with a succinct overview of material to be presented and ends with an annotated bibliography. For advanced undergraduate students, but will be essential reading for all researchers interested in the physics of neutrinos and what they reveal about the nature of the Universe.

There are few scientists of the twentieth century whose life's work has created more excitement and controversy than that of physicist David Bohm (1917-1992). Exploring the philosophical implication of both physics and consciousness, Bohm's penchant for questioning scientific and social orthodoxy was the expression of a rare and maverick intelligence. For Bohm, the world of matter and the experience of consciousness were two aspects of a more fundamental process he called the implicate order. Without a working sensibility of what this implicate order might be, our conceptions of the various threads of Bohm's work--whether in quantum theory or social dialogue remain incomplete. But with an enhanced understanding of such an order, the wholeness of Bohm's work becomes apparent and accessible. For the first time in a single volume, The Essential David Bohm offers a comprehensive overview of Bohm's original works from a non-technical perspective. Including three chapters of previously unpublished material, each reading has been selected to highlight some aspect of the implicate order process, and to provide an introduction to one of the most provocative thinkers of our time.

Excerpt from Preface:Albert Einstein was born on 14 March, 1879, in Ulm. When he was only six weeks old his parents moved to Munich, where he spent his infancy, and went to school until his fourteenth year. When fifteen he came to Switzerland, attended for another year the Gymnasium in Aarau, and took there his school leaving examination. Then he studied Mathematics and Physics in the Zurich Polytechnic, where Minkowski was one of his teachers. In 1902 he came to Berne as Engineer in the Patent Office, and in addition to his duties there, prepared himself for the examination for his Doctor's degree, which he took in the year 1905. At this time there appeared in rapid succession his first great works on the foundations of molecular physics, of which those relating to the Brownian motions are collected in this little volume...

In these engaging memoirs of a maverick, Theodore H. Maiman describes the life events leading to his invention of the laser in 1960. Maiman succeeded using his expertise in physics and engineering along with an ingenious and elegant design not anticipated by others. His pink ruby laser produced mankind’s first-ever coherent light and has provided transformational technology for commerce, industry, telecom, the Internet, medicine, and all the sciences. Maiman also chronicles the resistance from his employer and the ongoing intrigue by competing researchers in industry and academia seeking to diminish his contribution in inventing the first laser. This work will appeal to a wide readership, from physicists and engineers through science enthusiasts to general readers. The volume includes extensive photos and documentary materials related to Maiman’s life and accomplishments never before published. "No one beat Maiman to the laser. How important is the laser? How important are all lasers? That is how important we have to regard Maiman’s contribution.He and the laser changed all of our lives, everyone’s!"Dr. Nick Holonyak, Jr., Professor of Electrical and Computer Engineering and Physics, University of Illinois at Champaigne-Urbana, and inventor of the light-emitting diode (LED) and co-inventor of the transistor laser "More than five decades later, we can safely conclude that Theodore Maiman's groundbreaking discovery changed the world. Our modern life just as scientific research would be quite different without the laser."Dr. Ferenc Krausz, Director, Max Planck Institute for Quantum Optics, Garching, Germany, and Professor of Physics, Ludwig Maximilian University, Munich, and pioneer in attosecond lasers and attophysics "Maiman had the stroke of genius needed to take a different approach [from his competitors]. The sheer elegance and simplicity of his design beliesthe intellectual achievement it represents. If his invention seems obvious to some today, it was far from obvious in 1960."Jeff Hecht, authoritative science writer on the historical development of the laser, author of books on lasers and fiber optics
