Publication date: 06/18/2012

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.

Praise

[Bethe was] the supreme problem solver of the twentieth century.

—Freeman Dyson
Nuclear Forces is a carefully researched, historically and biographically insightful account of the development of a profession and of one of its leading representatives during a century in which physics and physicists played key roles in scientific, cultural, political, and military developments.

—David C. Cassidy, author of A Short History of Physics in the American Century
Schweber's account of Hans Bethe's life through his Nobel Prize-winning 1938 work on energy generation in stars reveals the origins of a charismatic scientist, grounded in the importance of his parents and his Jewish roots...[Schweber] recreates the social world that shaped the character of the last of the memorable young scientists who established the field of quantum mechanics.

—Publishers Weekly
A detailed and thoroughly researched study of Bethe's development as a scientist and as a human being...Schweber has trawled [Bethe's] correspondence [with Rudolf Peierls], together with Bethe's voluminous archive, with the finest of gauzes, and the result is a richly detailed picture of his life. Schweber tells it with compassion and admiration, although Nuclear Forces is no hagiography…This is a deeply rewarding book…[It's] an insightful account of how Hans Bethe became, in the constellation of 20th-century physicists, one of its most luminous stars.

—Graham Farmelo, Times Higher Education
Nuclear Forces is a highly readable account of a remarkable period in physics, tracing the future Nobel laureate through his formative years and up to the eve of World War II.

—Manjit Kumar, Wall Street Journal
Nuclear Forces, by the distinguished physicist Silvan Schweber, tells the story of the first three decades of Bethe's life and career, up to the time of his Nobel Prize–winning work on nuclear reactions in stars. But the book offers much more besides, with a history of the development of physics—atomic, solid-state and nuclear—in the first third of the twentieth century, and of the institutions in which Bethe worked. Schweber's analysis of the physics is the book's great strength.

—Frank Cose, Nature
Schweber, a physicist and historian of physics, provides an engaging account of the life of Hans Bethe...The book essentially ends just before the beginning of WW II. It gives the intellectual, cultural, and scientific background needed to understand Bethe's scientific work and his advocacy for control of nuclear weapons after the war.

—M. Dickinson, Choice
Through many interviews and a friendship going back fifty years, Schweber gives us a rare glimpse into the personal and professional life of this great man. The biography achieves the rare goal of being both scholarly and engaging.

—Ashutosh Jogalekar, Scientific American blog
