During World War 2, President Franklin D. Roosevelt and Prime Minister Winston Churchill pooled their nations' resources in the desperate race to beat the Germans to the secret of the atomic bomb. This book tells the story of the British scientists who journeyed to Los Alamos, New Mexico, to help develop the world's first nuclear weapons. The contributions of the British Mission to Los Alamos, which have been largely overlooked, were vital to the completion of the project. In addition, the two dozen scientists who collaborated with their American and Canadian allies were to have a profound effect on the post-War world, helping to shape the nuclear programs of the United States, Great Britain and, more controversially, the USSR.

The development of atomic bombs under the auspices of the U.S. Army’s Manhattan Project during World War II is considered to be the outstanding news story of the twentieth century. In this book, a physicist and expert on the history of the Project presents a comprehensive overview of this momentous achievement. The first three chapters cover the history of nuclear physics from the discovery of radioactivity to the discovery of fission, and would be ideal for instructors of a sophomore-level “Modern Physics” course. Student-level exercises at the ends of the chapters are accompanied by answers. Chapter 7 covers the physics of first-generation fission weapons at a similar level, again accompanied by exercises and answers. For the interested layman and for non-science students and instructors, the book includes extensive qualitative material on the history, organization, implementation, and results of the Manhattan Project and the Hiroshima and Nagasaki bombing missions. The reader also learns about the legacy of the Project as reflected in the current world stockpiles of nuclear weapons. This second edition contains important revisions and additions, including a new chapter on the German atomic bomb program and new sections on British and Canadian contributions to the Manhattan project and on feed materials. Several other sections have been expanded; reader feedback has been helpful in introducing minor corrections and improved explanations; and, last but not least, the second edition includes a detailed index.

Launched in 1942, the Manhattan Project was a well-funded, secret effort by the United States, the United Kingdom, and Canada to develop an atomic bomb before the Nazis. The results--the bombs named "Little Boy" and "Fat Man"--were dropped on Hiroshima and Nagasaki in August of 1945. A vast state within a state, the Manhattan Project employed 130,000 people and cost the United States and its allies 2 billion dollars, but its contribution to science as a prestigious investment was invaluable. After the bombs were dropped, states began allocating unprecedented funds for scientific research, leading to the establishment of many of twentieth century's major research institutions. Yet the union of science, industry, and the military did not start with the development of the atomic bomb; World War II only deepened the relationship. This absorbing history revisits the interactions among science, the national interest, and public and private funding that was initiated in World War I and flourished in WWII. It then follows the Manhattan Project from inception to dissolution, describing the primary influences that helped execute the world's first successful plan for nuclear research and tracing the lineages of modern national nuclear agencies back to their source.

**Winner of the Pulitzer Prize, the National Book Award, and the National Book Critics Circle Award** The definitive history of nuclear weapons—from the turn-of-the-century discovery of nuclear energy to J. Robert Oppenheimer and the Manhattan Project—this epic work details the science, the people, and the sociopolitical realities that led to the development of the atomic bomb. This sweeping account begins in the 19th century, with the discovery of nuclear fission, and continues to World War Two and the Americans’ race to beat Hitler’s Nazis. That competition launched the Manhattan Project and the nearly overnight construction of a vast military-industrial complex that culminated in the fateful dropping of the first bombs on Hiroshima and Nagasaki. Reading like a character-driven suspense novel, the book introduces the players in this saga of physics, politics, and human psychology—from FDR and Einstein to the visionary scientists who pioneered quantum theory and the application of thermonuclear fission, including Planck, Szilard, Bohr, Oppenheimer, Fermi, Teller, Meitner, von Neumann, and Lawrence. From nuclear power’s earliest foreshadowing in the work of H.G. Wells to the bright glare of Trinity at Alamogordo and the arms race of the Cold War, this dread invention forever changed the course of human history, and The Making of The Atomic Bomb provides a panoramic backdrop for that story. Richard Rhodes’s ability to craft compelling biographical portraits is matched only by his rigorous scholarship. Told in rich human, political, and scientific detail that any reader can follow, The Making of the Atomic Bomb is a thought-provoking and masterful work.

Though thousands of articles and books have been published on various aspects of the Manhattan Project, this book is the first comprehensive single-volume history prepared by a specialist for curious readers without a scientific background. This project, the United States Army’s program to develop and deploy atomic weapons in World War II, was a pivotal event in human history. The author presents a wide-ranging survey that not only tells the story of how the project was organized and carried out, but also introduces the leading personalities involved and features simplified but accurate descriptions of the underlying science and the engineering challenges. The technical points are illustrated by reader-friendly graphics. .

The incredible true story of a British physicist who was an undercover spy for the Soviets. The world first heard of Klaus Fuchs, the head of theoretical physics at the British Research Establishment at Harwell in February 1950 when he appeared at the Old Bailey, accused of passing secrets to the Soviet Union. For over sixty years disinformation and lies surrounded the story of Klaus Fuchs as the Governments of Britain, the United States and Russia all tried to cover up the truth about his treachery. Piecing together the story from archives in Britain, the United States, Russia and Germany, The Spy Who Changed the World unravels the truth about Fuchs and reveals for the first time his long career of espionage. It proves that he played a pivotal role in Britain's bomb program in the race to keep up with the United States in the atomic age, and that he revealed vital secrets about the atom bomb, as well as the immensely destructive hydrogen bomb to the Soviet Government. It is a dramatic tale of clandestine meetings, deadly secrets, family entanglements and illicit love affairs, all set against the tumultuous years from the rise of Hitler to the start of the Cold War.

The definitive collection of writings on the Manhattan Project by the pre-eminent scientists, historians, and the everyday observers who bore witness to the birth of the modern nuclear age. Begun in 1939, the Manhattan Project eventually employed more than 130,000 people, including our foremost scientists and thinkers, and cost nearly $2 billion, while operating under a shroud of absolute secrecy. This groundbreaking collection of documents, essays, articles, and excerpts from histories, biographies, plays, novels, letters, and the oral histories of key eyewitnesses provides unique perspectives for the historian and student of history all compiled by experts at the Atomic Heritage Foundation. Photographs throughout depict key moments and pivotal figures. The Manhattan Project gives actual voice to a significant period in history.

"Nuclear weapons, since their conception, have been the subject of secrecy. In the months after the dropping of the atomic bombs on Hiroshima and Nagasaki, the American scientific establishment, the American government, and the American public all wrestled with what was called the "problem of secrecy," wondering not only whether secrecy was appropriate and effective as a means of controlling this new technology but also whether it was compatible with the country's core values. Out of a messy context of propaganda, confusion, spy scares, and the grave counsel of competing groups of scientists, what historian Alex Wellerstein calls a "new regime of secrecy" was put into place. It was unlike any other previous or since. Nuclear secrets were given their own unique legal designation in American law ("restricted data"), one that operates differently than all other forms of national security classification and exists to this day. Drawing on massive amounts of declassified files, including records released by the government for the first time at the author's request, Restricted Data is a narrative account of nuclear secrecy and the tensions and uncertainty that built as the Cold War continued. In the US, both science and democracy are pitted against nuclear secrecy, and this makes its history uniquely compelling and timely"--

Churchill's Bomb - from the author of the Costa award-winning biography The Strangest Man - reveals a new aspect of Winston Churchill's life, so far completely neglected by historians: his relations with his nuclear scientists, and his management of Britain's policy on atomic weapons. Churchill was the only prominent politician to foresee the nuclear age and he played a leading role in the development of the Bomb during World War II. He became the first British Prime Minister with access to these weapons, and left office following desperate attempts during the Cold War to end the arms race. Graham Farmelo traces the beginnings of Churchill's association with nuclear weapons to his unlikely friendship with H. G. Wells, who coined the term 'atomic bombs'. In the 1930s, when Ernest Rutherford and his brilliant followers, such as Chadwick and Cockcroft, gave Britain the lead in nuclear research, Churchill wrote several widely read newspaper articles on the huge implications of their work. British physicists, in 1940, first showed that the Bomb was a practical possibility. But Churchill, closely advised by his favourite scientist, the controversial Frederick Lindemann, allowed leadership to pass to the US, where the Manhattan Project made the Bomb a terrible reality. British physicists played only a minor role in this vast enterprise, while Churchill ignored warnings from the scientist Niels Bohr that the Anglo-American policy would lead to a post-war arms race. After the war, the Americans reneged on personal agreements between Roosevelt and Churchill to share research. Clement Attlee, in a fateful decision, ordered the building of a British Bomb to maintain the country's place among the great powers. Churchill inherited it and ended his political career obsessed with the threat of thermonuclear war. Churchill's Bomb is an original and controversial book, full of political and scientific personalities and intrigues, which reveals a little-known side of Britain's great war-leader.
