In a clear, nontechnical account, Jack Goldstein tells the story of this entrepreneurial American scientist who played an essential part in experiments important to the development of quantum mechanics, who later became an advisor to the government during much of the Cold War period, and whose leadership in educational reform resulted in the restructuring of the entire American high school science curriculum. Jerrold Zacharias (1905-1986) was a physicist well placed by historical circumstance to take a central part in the development of American science, science policy, and science education. In a clear, nontechnical account, Jack Goldstein tells the story of this entrepreneurial American scientist who played an essential part in experiments important to the development of quantum mechanics, who later became an advisor to the government during much of the Cold War period, and whose leadership in educational reform resulted in the restructuring of the entire American high school science curriculum. Zacharias lived at a time when an individual with imagination and courage could make a difference, whether at the forefront of science or in matters of public policy. He believed that every citizen, even those with modest scientific sophistication and knowledge, could learn to think like a scientist. Now, at a time when the issues of science education and science literacy are again of compelling national interest, his ideas merit close attention.Goldstein describes Zacharias's coming of scientific age in the early 1930s, as a member of 1. 1. Rabi's group at Columbia, and examines the leading role he played during World War II at MIT's Radiation Laboratory and at the Manhattan Project. From about 1955 on, Goldstein observes, Zacharias made significant contributions to science education in physics, chemistry, biology, and mathematics at the primary, secondary, and college levels. As a result of his initiatives, science and mathematics curriculum development flourished in a number of third-world countries.
Leo Szilard conceived of the possibility of nuclear fission sustained by a chain reaction years before it was achieved in the laboratory. He was also one of the initiators of the atomic bomb project in the United States. Yet he dedicated his final years to the causes of understanding and sustaining life. The eminent physicist became a biologist and a vital force calling, for the control of nuclear and other weapons.This book documents Szilard's energetic attempts to influence public policy on arms control and disarmament issues, both through open political processes and statements and through behindthe-scenes contacts with Washington power sources and a remarkable exercise in personal diplomacy with Nikita Khrushchev.Many of the issues Szilard deals with in this valuable record of the years 1947-1963 are still crucial today. His opposition to antiballistic missile systems, his proposal for a Washington-Moscow "hot line," his work on the Pugwash conferences that brought together scientists from the East and the West, his pivotal role in the creation of the Council for a Livable World, his advocacy of a nuclear policy of no-first-use and restricted retaliation, and his support of "minimum deterrence" in place of an overwhelming counterforce capability - all these matters are as important in the 1980s as they were in the 1950s and 1960s.Helen S. Hawkins and G. Allen Greb are affiliated with the Institute on Global Conflict and Cooperation, University of California, San Diego. The late Gertrud Weiss Szilard also served as coeditor of the first two volumes of her husband's work: The Collected Works of Leo Szilard: Scientific Papers and Leo Szilard: His Version of the Facts. Barton J. Bernstein is professor in the Department of History, Stanford University.
This major work covers almost all that has been learned about the acoustics of stringed instruments from Helmholtz's 19th-century theoretical elaborations to recent electroacoustic and holographic measurements. Many of the results presented here were uncovered by the author himself (and by his associates and students) over a 20-year period of research on the physics of instruments in the violin family. Lothar Cremer is one of the world's most respected authorities on architectural acoustics and, not incidentally, an avid avocational violinist and violist. The book-which was published in German in 1981-first of all meets the rigorous technical standards of specialists in musical acoustics. But it also serves the needs and interests of two broader groups: makers and players of stringed instruments are expressly addressed, since the implications of the mathematical formulations are fully outlined and explained; and acousticians in general will find that the work represents a textbook illustration of the application of fundamental principles and up-to-date techniques to a specific problem. The first-and longest-of the book's three parts investigates the oscillatory responses of bowed (and plucked) strings. The natural nonlinearities that derive from considerations of string torsion and bending stiffness are deftly handled and concisely modeled. The second part deals with the body of the instrument. Special attention is given to the bridge, which transmits the oscillations of the strings to the wooden body and its air cavity. In this case, linear modeling proves serviceable for the most part-a simplification that would not be possible with lute-like instruments such as the guitar. The radiation of sound from the body into the listener's space, which is treated as an extension of the instrument itself, is the subject of the book's final part.

The first volume of the Brandeis University Summer Institute lecture series of 1970 on theories of interacting elementary particles, consisting of four sets of lectures. Every summer since 1959 Brandeis University has conducted a lecture series centered on various areas of theoretical physics. The areas are sufficiently broad to interest a large number of physicists and the lecturers are among the original explorers of these areas. The 1970 lectures, presented in two volumes, are on theories of interacting elementary particles. The four lecturers of Volume 1, and the range of the topics they cover, are as follows: Stephen L. Adler (Institute for Advanced Study) on "Perturbation Theory Anomalies": introduction and review of perturbation theory; the VVA triangle anomaly; absence of radiative corrections; generalizations of our results; connection between Ward identity anomalies and commutator (Bjorken-limit) anomalies; applications of the Bjorken limit; and breakdown of the Bjorken limit in perturbation theory. Stanley Mandelstam (University of California at Berkeley) on "Dynamical Applications of the Veneziano formula for the four-point scalar amplitude; factorization; the operator formalism; Veneziano-type quark models; and higher-order Feynman-like diagrams. Steven Weinberg (Massachusetts Institute of Technology) on "Dynamic and Algebraic Symmetries": Introduction; hadron electrodynamics; local symmetries; and chirality. Wolfhart Zimmermann (New York University) on "Local Operator Products and Renormalization in Quantum Field Theory": introduction; renormalization; operator product expansions; and local field equations. The second volume contains lectures by Rudolf Haag on observables and fields, by Maurice Jacob on duality, by Michael Reed on non-Fock representations, and by Bruno Zumino on effective Lagrangians and broken symmetries.
A comprehensive overview of holographic methods in quantum matter, written by pioneers in the field. This book, written by pioneers in the field, offers a comprehensive overview of holographic methods in quantum matter. It covers influential developments in theoretical physics, making the key concepts accessible to researchers and students in both high energy and condensed matter physics. The book provides a unique combination of theoretical and historical context, technical results, extensive references to the literature, and exercises. It will give readers the ability to understand the important problems in the field, both those that have been solved and those that remain unsolved, and will enable them to engage directly with the current literature. The book describes a particular interface between condensed matter physics, gravitational physics, and string and quantum field theory made possible by holographic duality. The chapters cover such topics as the essential workings of the holographic correspondence; strongly interacting quantum matter at a fixed commensurate density; compressible quantum matter with a variable density; transport in quantum matter; the holographic description of symmetry broken phases; and the relevance of the topics covered to experimental challenges in specific quantum materials. Holographic Quantum Matter promises to be the definitive presentation of this material. |
