``Nuclear Physics'' deals with Bohr's work on nuclear physics which began in the pre-1932 days with his thinking deeply, but inconclusively about the seeming contradictions then presented by the evidence about the nucleus. In 1936, Bohr recognised and described the insights provided by neutron scattering experiments; the excitement of this new understanding and its extension and consolidation occupied much of the subsequent years. In 1939, he was again first in understanding the essential features of the newly discovered phenomenon of fission, applying successfully the point of view of nuclear reactions which he had developed over the past three years. Later, in 1949-50, he was impressed by the success of the nuclear shell model, which on the face of it seemed hard to reconcile with the picture of the closely interacting nucleons which he had pioneered in 1936. Bohr put much effort into clarifying this paradox.

Since the Niels Bohr centenary of 1985 there has been an astonishing international surge of scholarly analyses of Bohr's philosophy. Now for the first time in Niels Bohr and Contemporary Philosophy Jan Faye and Henry Folse have brought together sixteen of today's leading authors who have helped mould this new round of discussions on Bohr's philosophy. In fifteen entirely new, previously unpublished essays we discover a surprising variety of the different facets of Bohr as the natural philosopher whose `framework of complementarity' shaped the final phase of the quantum revolution and influenced two generations of the century's leading physicists. There is much on which the authors included here agree; but there are also polar disagreements, which assure us that the philosophical questions revolving around Bohr's `new viewpoint' will continue to be a subject of scholarly interest and discussion for years to come. This collection will interest all serious students of history and philosophy of science, and foundations of physics.

Denmark is the oldest monarchy in Europe. At different points in its history, Denmark's boundaries have encompassed England, Sweden, West Africa, India, and the West Indies. Despite its changing and relatively small boundaries, Denmark has played a much larger part in the politics of Europe than might be expected. Additionally, through its territories (Faroe Islands and Greenland), Denmark has managed to retain an important presence in the North Atlantic. Today, democratic Denmark, with its thriving capital Copenhagen, is peaceful, prosperous, and progressive. Within NATO, Denmark has contributed to peace-keeping in the Persian Gulf and Bosnia. The "Danish Model" of welfare gives Danes a real sense of social security and presents many naysayers with a provocative example of a successfully managed welfare state. Danes have a reputation for inventiveness and good design, whether in architecture, furniture, or industrial design. The A to Z of Denmark relates the history of this successful country through a chronology, an introductory essay, appendixes, a bibliography, and hundreds of cross-referenced dictionary entries on kings, politicians, officials, explorers, authors, architects, composers, painters, astronomers, educationists, reformers, political parties, social movements, and other aspects of Danish society.

Denmark has a millennium-long continuous history and development from Viking times (about 800-1050 AD) to the modern welfare state. The resilience of the Danish people is evident in the artistic golden age of the early 19th century despite national bankruptcy, the agricultural revival during the final third of the 19th century. Modern Denmark leads in industrial design, furniture, engineering, pharmacy, and social development in the 20th century. Danish scientists, medical doctors, composers, musicians, choreographers, playwrights, authors, sculptors, architects, designers, painters and film directors have made significant contributions to the development of European culture. In the 21st century, Denmark combines a thriving and highly productive modern economy with extensive social care and welfare, and thus refutes the neo-conservative economists who claim that such a combination is impossible. In short, Denmark is seen by the Danes and their neighbors as a very good place to live. This third edition of Historical Dictionary of Denmark contains a chronology, an introduction, appendixes, and an extensive bibliography. The dictionary section has over 1000 cross-referenced entries on important personalities, politics, economy, foreign relations, religion, and culture. This book is an excellent access point for students, researchers, and anyone wanting to know more about Denmark.

Niels Bohr: Collected Works, Volume 13: Cumulative Subject Index documents aspects of Niels Bohr's varied life and work in the form of a cumulative subject index, with emphasis on his scientific contributions in the field of physics. The general organization of the material is thematic rather than strictly chronological, allowing for the presentation of each paper (or group of papers) along with other relevant material such as drafts, notes, letters, and other items. The book is illustrated with rare photos and includes explanatory notes as well as a bibliography. The bibliography is restricted to the versions of Bohr's publications reproduced in this volume and encompasses a wide range of topics in physics, from the determination of the surface tension of water by the method of jet vibration to the electron theory of metals and of thermoelectric phenomena; the theory of the decrease of velocity of moving electrified particles on passing through matter; the constitution of atoms and molecules; and the spectra of helium and hydrogen. Bohr's other papers focus on the effect of electric and magnetic fields on spectral lines; the quantum theory of radiation and the structure of the atom; the polarization of radiation in the quantum theory; and collisions between atomic systems and free electrical particles. This monograph will be useful to students, practitioners, and researchers interested in Bohr's life and work in general and in quantum mechanics in particular.

This edition of the private and scientific correspondence of Sir Rudolf Peierls gives a unique insight into the life and work of one of the greatest theoretical physicists of the 20th century. Rudolf Peierls' scientific work contributed to the early developments in quantum mechanics, and he is well known and much appreciated for his contributions to various disciplines, including solid state physics, nuclear physics, and particle physics. As an enthusiastic and devoted teacher, he passed on his knowledge and understanding and inspired the work of collaborators and students alike. As an effective administrator he was responsible, almost single-handedly, for the establishment of an outstanding successful centre of theoretical physics in Birmingham, and later contributed much to theoretical physics in Oxford.A meticulous collector of correspondence, Sir Rudolf left a fascinating collection of letters, in some cases spanning more than seven decades. This collection includes correspondence with his parents, his wife, the Russian-born physicist Genia Kannegieser, life-long friends such as Hans Bethe, and many great physicists, including Wolfgang Pauli, Niels Bohr, Werner Heisenberg, Lev Landau, and George Placzek, to name but a few.This first volume, which covers the years 1922 to 1945, contains much of the early family correspondence, letters exchanged between Rudolf and Genia Peierls before and after their marriage in 1931, correspondence relating to early developments in quantum physics, and interesting material relating to the development of nuclear weapons. The extensive apparatus provides an invaluable background which allows the reader to put the presented documents into their multi-faceted social, political and scientific context.

The true history of physics can only be read in the life stories of those who made its progress possible. Matvei Bronstein was one of those for whom the vast territory of theoretical physics was as familiar as his own home: he worked in cosmology, nuclear physics, gravitation, semiconductors, atmospheric physics, quantum electrodynamics, astro physics and the relativistic quantum theory. Everyone who knew him was struck by his wide knowledge, far beyond the limits of his trade. This partly explains why his life was closely intertwined with the social, historical and scientific context of his time. One might doubt that during his short life Bronstein could have made truly weighty contributions to science and have become, in a sense, a symbol ofhis time. Unlike mathematicians and poets, physicists reach the peak oftheir careers after the age of thirty. His thirty years of life, however, proved enough to secure him a place in theGreaterSovietEncyclopedia. In 1967, in describing the first generation of physicists educated after the 1917 revolution, Igor Tamm referred to Bronstein as "an exceptionally brilliant and promising" theoretician [268].
