This book traces the history of Arnold Sommerfeld’s famous “nursery of theoretical physics” at the University of Munich and demonstrates the centrality of developing personal and institutional networks for the emergence of quantum theory. Sommerfeld, originally a mathematician with little interest in theoretical physics, was a somewhat unlikely choice for a chair of theoretical physics when he was appointed in 1906. However, he quickly reoriented his research focus towards physics, forstering a keen interest in experimental research. Possibly even more important for the development of quantum theory in the coming years was his exceptional talent as a charismatic teacher and prolific networker, which turned Munich into a central node in the fast-growing network of quantum physicists in the 1920s. It is no coincidence that the two most talented “child prodigies” of 1920s quantum physics, Wolfgang Pauli and Werner Heisenberg, were his students, nor that by the end of the decade about a dozen of Sommerfeld’s former disciples held chairs in theoretical physics. The book is directed at historians of science and physics, as well as all those interested in the history of science diplomacy and networking. The book is part of a series of publications on the early network of quantum physics. These works emerged from an expansive study on the quantum revolution as a major transformation of physical knowledge undertaken by the Max Planck Institute for the History of Science and the Fritz Haber Institute (2006–2012).

This book explores Albert Einstein’s move to Berlin and the establishment of the Kaiser Wilhelm Institute for Physics under his directorship. Einstein’s call to Berlin was supported by a group of prominent physicists, including Fritz Haber, Walter Nernst, Max Planck, Heinrich Rubens, Emil Warburg, and the young astronomer Erwin Freundlich, in the expectation that Einstein and the institute would take the lead in advancing quantum physics in its early phase. Examining both the abortive attempt and the successful opening of the institute in 1917, it also discusses in detail the institute’s activities up to 1922, when Einstein relinquished the directorship, as well as his reasons for stepping down. The final chapter evaluates the institute’s activities and its role in the advancement of physics. In the end, the institute only partially fulfilled the expectations of its promoters because of the waning interest in quantum physics on the part of its director and board, and also because of Einstein’s refusal to exert scientific leadership. The book is part of a series of publications in the SpringerBriefs series on the early network of quantum physics. The other books in the four-volume collection address the beginnings of quantum physics research at Göttingen, Copenhagen, and Munich. These works emerged from an expansive study on the quantum revolution as a major transformation of physical knowledge undertaken by the Max Planck Institute for the History of Science and the Fritz Haber Institute (2006–2012).

Quantum mechanics – the grandiose theory that describes nature down to the submicroscopic level – was first formulated in Göttingen in 1925. How did this come about and why is it that Göttingen became the pre-eminent location for a revolution in physics? This book is the first to investigate the wide range of factors that were pivotal for quantum physics to be established in Göttingen. These include the process of generational change of physics professors, the hopes of mathematicians seeking new fields of research, and a new understanding of the interplay of experiment, theory and philosophy.

This book is a historical analysis of the quantum mechanical revolution and the emergence of a new discipline from the perspective, not of a professor, but of a recent or actual Ph.D. student just embarking on an uncertain academic career in economically hard times. Quantum mechanics exploded on to the intellectual scene between 1925 and 1927, with more than 200 publications across the world, the majority of them authored by young scientists under the age of 30, graduate students or postdoctoral fellows. The resulting theory was a collective product that no single authority could claim, but it had a major geographical nod – the Copenhagen Institute of Theoretical Physics – where most of the informal, pre-published exchange of ideas occurred and where every participant of the new community aspired to visit. A rare combination of circumstances and resources – political, diplomatic, financial, and intellectual – allowed Niels Bohr to establish this “Mecca” of quantum theory outside of traditional and more powerful centres of science. Transitory international postdoctoral fellows, rather than established professors, developed a culture of research that became the source of major innovations in the field. Temporary assistantships, postdoctoral positions, and their equivalents were the chief mode of existence for young academics during the period of economic crisis and post-WWI international tensions. Insecure career trajectories and unpredictable moves through non-stable temporary positions contributed to their general outlook and interpretations of the emerging theory of quantum mechanics. This book is part of a four-volume collection addressing the beginnings of quantum physics research at the major European centres of Göttingen, Copenhagen, Berlin, and Munich; these works emerged from an expansive study on the quantum revolution as a major transformation of physical knowledge undertaken by the Max Planck Institute for the History of Science and the Fritz Haber Institute (2006–2012).

From April through December of 1945, ten of Nazi Germany's greatest nuclear physicists were detained by Allied military and intelligence services in a kind of gilded cage at Farm Hall, an English country manor near Cambridge. The physicists knew the Reich had failed to develop an atomic bomb, and they soon learned, from a BBC radio report on August 6, that the Allies had succeeded in their own efforts to create such a weapon. But what they did not know was that many of their meetings and private conversations were being monitored and recorded by British agents. This book contains the complete collection of transcripts that were made from these secret recordings, providing an unprecedented view of how the German scientists, including two Nobel Laureates, thought and spoke about their roles during the war.
