Part I is devoted to Niels Bohr's mission to promote an "open world" between nations, that is, full sharing of information in the scientific and technical, as well as in the cultural spheres the scientific and technical, as well as in the cultural spheres. He started his mission immediately upon escaping from Nazi-occupied Denmark in the autumn of 1943, when he realized that the bomb was on the way to becoming a reality. As he wrote in 1944, he considered that the existence of the atomic bomb "would not only seem to necessitate but should also, due to the urgency of mutual confidence, facilitate" the realization of an open world. During the Second World War, while being actively involved in the Allied atomic bomb project, Bohr was able to obtain access to Prime Minister Churchill and President Roosevelt to promote his view. After the war he continued his confidential approaches to the statesmen while publishing more generally oriented articles on the issue. Although Bohr put in as much work in appeals to the statesmen as in his other writings, they were not intended for publication. This has called for the inclusion of a greater number than in earlier volumes of the Collected Works of previously unpublished documents as well as a particularly extensive historical introduction written by the editor. The material adds up to a fascinating sotry of the political dedication and social responsibility ofone of the major scientists of the twentieth century. Part II documents Bohr's other social and political activities, such as his long-time presidency in the Royal Danish Academy of Sciences and Letters and his promotion of the peaceful uses of atomic energy. Taking a broader approach than most of his other publications, these occasional writings, which are most often published versions of talks at public events, are particularly well suited to present Bohr to the general public, as a thinker as well as a person.* Niels Bohr* Open World* Atomic Bomb Project* Science and Politics* Collected Works* Archival Documents* Original Photographs

Weird Scientists is a sequel to Men of Manhattan. As I wrote the latter about the nuclear physicists who brought in the era of nuclear power, quantum mechanics (or quantum physics) was unavoidable. Many of the contributors to the science of splitting the atom were also contributors to quantum mechanics. Atomic physics, particle physics, quantum physics, and even relativity are all interrelated. This book is about the men and women who established the science that shook the foundations of classical physics, removed determinism from measurement, and created alternative worlds of reality. The book introduces fundamental concepts of quantum mechanics, roughly in the order they were discovered, as a launching point for describing the scientist and the work that brought forth the concepts.

A new approach to nuclear disarmament, nonproliferation, and the prevention of nuclear terrorism that focuses on controlling the production and stockpiling of nuclear materials. Achieving nuclear disarmament, stopping nuclear proliferation, and preventing nuclear terrorism are among the most critical challenges facing the world today. Unmaking the Bomb proposes a new approach to reaching these long-held goals. Rather than considering them as separate issues, the authors—physicists and experts on nuclear security—argue that all three of these goals can be understood and realized together if we focus on the production, stockpiling, and disposal of plutonium and highly enriched uranium—the fissile materials that are the key ingredients used to make nuclear weapons. The authors describe the history, production, national stockpiles, and current military and civilian uses of plutonium and highly enriched uranium, and propose policies aimed at reducing and eventually eliminating these fissile materials worldwide. These include an end to the production of highly enriched uranium and plutonium for weapons, an end to their use as reactor fuels, and the verified elimination of all national stockpiles.

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.
