First published in 1976, The Advisors is an absorbing look at the technical, strategic, and human aspects of the great debate that led to the decision to build the first hydrogen bomb, Based on the author's own participation in Project Superbomb, on interviews with other participants, and on declassified documents, this book explains the complete background to this major acceleration of the nuclear arms race. For this reissue, the author has written a new Preface and Epilogue. The reissue also includes a recently declassified essay by Hans A. Bethe discussing the history of the H-bomb project from his unique vantage point as Director of the Theoretical Division at Los Alamos. He has revised the essay specifically for inclusion in this book.
Edward Teller is perhaps best known for his belief in freedom through strong defense. But this extraordinary memoir at last reveals the man behind the headlines--passionate and humorous, devoted and loyal. Never before has Teller told his story as fully as he does here. We learn his true position on everything from the bombing of Japan to the pursuit of weapons research in the post-war years. In clear and compelling prose, Teller chronicles the people and events that shaped him as a scientist, beginning with his early love of music and math, and continuing with his study of quantum physics under Werner Heisenberg. He also describes his relationships with some of the century's greatest minds--Einstein, Bohr, Fermi, Szilard, von Neumann--and offers an honest assessment of the development of the atomic and hydrogen bombs, the founding of Lawrence Livermore Laboratory, and his complicated relationship with J. Robert Oppenheimer.Rich and humanizing, this candid memoir describes the events that led Edward Teller to be honored or abhorred, and provides a fascinating perspective on the ability of a single individual to affect the course of history.
When Hans Bethe, at the age of 97, asked his long-term collaborator, Gerry Brown, to explain his scientific work to the world, the latter knew that this was a steep task. As the late John Bahcall famously remarked: ?If you know his (Bethe's) work, you might be inclined to think he is really several people, all of whom are engaged in a conspiracy to sign their work with the same name?. Almost eight decades of original research, hundreds of scientific papers, numerous books, countless reports spanning the key areas of 20th century physics are the impressive record of Hans Bethe's academic work.In answering Bethe's request, the editors enlisted the help of experts in the different research fields, collaborators and friends of this ?last giant? of 20th century physics. Hans Bethe and His Physics is the result. It contains discussions of Hans Bethe's work in solid state physics, nuclear physics and astrophysics; it explains his contributions as a science advisor and his stance on energy and nuclear weapons; and it demonstrates his impact as a teacher and mentor to generations of young scientists. While the book's primary aim is to explain the science behind the man, the different articles also allow the reader to take a glimpse at the man behind the science.
The relationship of repentance to redemption in Jeremiah is a problem compounded of authenticity and redaction. From an intensive analysis of the relevant texts and a review of the secondary literature, Unterman argues that the dominant trend of scholarship is methodologically flawed and biased. The Jeremianic texts dealt with in this study represent concepts and vocabulary which influence or logically precede Ezekiel and II Isaiah, fit the historical background of the late 7th and 6th centuries BCE, and relate to, but are essentially different from, the literature known as Deuteronomistic. Jeremiah's thought on the relationship of repentance to redemption is to be understood from the historical and ideological background of the prophet himself. This thought progressed through three stages: in Jeremiah's early prophecies on redemption human repentance and divine mercy are equal factors; between 597 and 587 repentance plays a secondary role to YHWH's mercy; during the period of the destruction of Jerusalem the prophet's despair at the people's inability to repent results in the elimination of the demand for repentance, so that redemption would now depend solely on God's mercy. Included in this study are excursuses on the prophets Amos, Hosea, Ezekiel and II Isaiah, which help to place Jeremiah's thought in historical perspective.
On the fiftieth anniversary of Hiroshima, Nobel-winning physicist Hans Bethe called on his fellow scientists to stop working on weapons of mass destruction. What drove Bethe, the head of Theoretical Physics at Los Alamos during the Manhattan Project, to renounce the weaponry he had once worked so tirelessly to create? That is one of the questions answered by Nuclear Forces, a riveting biography of Bethe’s early life and development as both a scientist and a man of principle. As Silvan Schweber follows Bethe from his childhood in Germany, to laboratories in Italy and England, and on to Cornell University, he shows how these differing environments were reflected in the kind of physics Bethe produced. Many of the young quantum physicists in the 1930s, including Bethe, had Jewish roots, and Schweber considers how Liberal Judaism in Germany helps explain their remarkable contributions. A portrait emerges of a man whose strategy for staying on top of a deeply hierarchical field was to tackle only those problems he knew he could solve. Bethe’s emotional maturation was shaped by his father and by two women of Jewish background: his overly possessive mother and his wife, who would later serve as an ethical touchstone during the turbulent years he spent designing nuclear bombs. Situating Bethe in the context of the various communities where he worked, Schweber provides a full picture of prewar developments in physics that changed the modern world, and of a scientist shaped by the unprecedented moral dilemmas those developments in turn created.
“Blaedel has addressed himself to the task of writing a full-length biography that covers all facets of his subject and that emphasizes that they form part of one harmonious unity. I think that on the whole he has succeeded remarkably well. He gives an accurate picture of the man theorists of my generation both admired and loved. And not only of the physicist: Bohr’s relations with his family and in particular with his wife, an admirable woman, are drawn with sympathy and understanding. Blaedel’s sketch of the atmosphere at Bohr’s institute in Copenhagen... is true to life; it will raise nostalgic memories among those who, like myself, experienced it... [Blaedel] has produced a fitting tribute to a great scientist and a noble man.” — H.B.G. Casimir, Nature “The book is intended primarily for nonphysicists; nevertheless it offers extensive (albeit nontechnical) accounts of all aspects of Bohr’s scientific work. The consistent emphasis, however, is on Bohr as a person—his character, interests andWeltanschauung. Niels Blaedel was able to draw on matchless resources, both human and material: Bohr’s family (especially his widow, Margrethe Bohr, who shared both her memories and her correspondence), Bohr’s former friends and colleagues, and a rich supply of documentary and photographic material from Danish collections, as well as from the AIP Niels Bohr Library in New York. The result is a lavishly illustrated and affectionate account of Bohr from his earliest years until his death... as a general picture of Bohr and his work this book can be warmly recommended.” — Anthony P. French, Physics Today “Niels Bohr is generally regarded as a giant of twentieth-century physics... Bohr was securely entrenched in a Danish culture that is difficult for many historians to penetrate. It is important, then, that at last a biography has been written by a Dane with wide knowledge of the society in which Bohr lived and moved... The author had unprecedented access to Bohr’s family correspondence, primarily with his wife Margrethe, who, before she died at ninety-four in 1984, read Blaedel many letters from her husband... Blaedel’s book, written on commission for the Bohr centennial and published in Danish in 1985, contains valuable insights on Bohr, particularly as they relate to his previously unavailable family correspondence and his place in Danish culture.” — Finn Aaserud, Isis: A Journal of the History of Science “Though Niels Bohr is best known as a distinguished citizen of the international community of science, he was also a leading citizen of Denmark. This is the first biography of Bohr to deal with both of these dimensions to his life, without which it is hard to fully understand either the man or his work.” — Robert March, University of Wisconsin-Madison, author of Physics for Poets “... the book can be read without any background knowledge in physics. But its overwhelming number of photographs and rich use of letters and recollections make Niels Blaedel’s book closely resemble the great standard biography — a literary monument to Niels Bohr.” — Flemming Christian Nielsen, Jyllands-Posten “Niels Blaedel has solved an almost insoluble problem... thereby clarifying the life of Niels Bohr... a well-constructed piece of documentation and a coherent piece of scientific history.” — Jens Kistrup, Berlingske Tidende
