There is something in this, although well-written biographies will have a place in literature so long as readers are interested in individual human beings as well as their culture and development. Scientific biographies are especially problematic for scholars.

One reason for this is that science is above all a communitarian activity - individuals rarely matter much, as their work is always dispensable in the long run. If Marie Curie or Einstein had never lived, their contributions would have been made by others, probably sooner rather than later. Yet the notion that these great scientists are just high-profile actors who got lucky in the socio-political pageant will not wash. As the community of scientists is always aware, a small number of them are almost unfathomably gifted and productive, as outstandingly creative as J.

Selected Works of Hans A Bethe

Such figures hold a fascination not just for their peers but also for non-specialists, who quite reasonably want to understand why. Apart from his experiences as a young student, he immersed himself in the culture of three scientific institutions that, Schweber argues persuasively, shaped Bethe as a theoretical physicist. Most important for Bethe was the influence of his thesis adviser at the University of Munich, Arnold Sommerfeld, who is often underrated in histories of quantum theory, although his hypercritical former student Wolfgang Pauli rated him as one of the greats.

It was Sommerfeld who impressed on Bethe the importance of the mysterious harmony between mathematics and physics and, at the same time, of testing candidate theories by using them to make clear-cut predictions. Bethe would become a theorist with his feet firmly on the experimental ground, ingeniously applying the new quantum theory to atoms, molecules and solid materials.

Schweber brilliantly underlines the importance to Bethe of being part of the collegiate atmospheres that Rutherford and Fermi set up.

Blessed with a first-rate analytical mind, a nose for good problems and a knowledge of his limits, Bethe was ideally placed to thrive. Sure enough, in the late s he identified the complex series of nuclear reactions that power the stars, work that led to his Nobel Prize in Physics in By the time Bethe was well established, he had made two friendships that played a large part in his life - with the Hungarian-born Edward Teller and the German-born Rudolf Peierls.

All three fled Europe in the s and played crucial roles in the development of nuclear weapons, Bethe and Teller eventually settling in the US, Peierls in the UK. Schweber sheds a good deal of light on these friendships, drawing on the illuminating letters between Bethe and Peierls, which continued until they were separated by death. Schweber tells it with compassion and admiration, although Nuclear Forces is no hagiography.

It is painful to read his account of how the blazingly ambitious Bethe suddenly abandoned plans for a wedding, an act the jilted fiancee still remembers bitterly. Scientific biographers - or rather their publishers - have neglected him, preferring instead to write the umpteenth life of Albert Einstein, Richard Feynman, Robert Oppenheimer and a few other bankable names.

Silvan Schweber wrote about Bethe 12 years ago in a short book that compared and contrasted his reaction to the ethical and moral challenges of the Bomb with those of Oppenheimer. Nuclear Forces begins on an apologetic note, with a reminder that biography has always been considered the poor relation in the discipline of history.

All three fled Europe in the s and played crucial roles in the development of nuclear weapons, Bethe and Teller eventually settling in the US, Peierls in the UK. During , as a Rockefeller Foundation fellow, Bethe spent a semester at the University of Cambridge under the aegis of Ralph Fowler and a semester at the University of Rome working with Enrico Fermi.

This craftsmanship was displayed in full force in the many reviews that Bethe wrote. His two book-length reviews in the Handbuch der Physik —the first with Sommerfeld on solid-state physics and the second on the quantum theory of one- and two-electron systems—exhibited his remarkable powers of synthesis. Along with a review on nuclear physics in Reviews of Modern Physics —37 , these works were instant classics.

They usually contained much new material that Bethe had worked out in their preparation. Sommerfeld was able to help him by awarding him a fellowship for the summer of , and he got William Lawrence Bragg to invite him to the University of Manchester , Eng.

Bethe then went to the University of Bristol for the fall semester before accepting a position at Cornell University , Ithaca, N. He arrived at Cornell in February , and he stayed there for the rest of his life. Bethe came to the United States at a time when the American physics community was undergoing enormous growth.

The Washington Conferences on Theoretical Physics were paradigmatic of the meetings organized to assimilate the insights quantum mechanics was giving to many fields, especially atomic and molecular physics and the emerging field of nuclear physics. Bethe attended the and Washington Conferences, but he agreed to participate in the conference on stellar energy generation only after repeated urgings by Edward Teller. As a result of what he learned at the latter conference, Bethe was able to give definitive answers to the problem of energy generation in stars.

By stipulating and analyzing the nuclear reactions responsible for the phenomenon, he explained how stars could continue to burn for billions of years. His Physical Review paper on energy generation in stars created the field of nuclear astrophysics and led to his being awarded the Nobel Prize. He and the division were part of the Manhattan Project , and they made crucial contributions to the feasibility and design of the uranium and the plutonium atomic bombs.

Hans Bethe’s early life

The years at Los Alamos changed his life. In the aftermath of the development of these fission weapons , Bethe became deeply involved with investigating the feasibility of developing fusion bombs, hoping to prove that no terrestrial mechanism could accomplish the task.

He believed their development to be immoral. When the Teller-Ulam mechanism for igniting a fusion reaction was advanced in and the possibility of a hydrogen bomb , or H-bomb, became a reality, Bethe helped to design it. He believed that the Soviets would likewise be able to build one and that only a balance of terror would prevent their use. He became a relentless champion of nuclear arms control , writing many essays collected in The Road from Los Alamos [].
