The present volume, set in the turbulent post-World War I period, finds Einstein awaiting news of the 1919 British eclipse expedition to test the general relativistic prediction of the deflection of starlight by the sun. With the expedition's success, he becomes the first science celebrity of our age. Deeply interested in the other, stellar redshift test of his theory, Einstein supports astronomers engaged in experimental work on the issue. Piqued by early suggestions of a unified field theory, he ponders how to unify gravitation and electromagnetic field theory and also works to resolve contradictions between the new quantum physics and relativity. His open-minded exchanges with colleagues may challenge his later image as the stubborn critic of quantum mechanics. We see Einstein deeply engaged in discussing social and political issues, participating in humanitarian efforts, and intervening on behalf of intellectuals condemned to death after the fall of the Bavarian Soviet republic. He faced anti-Semitic outbursts, reflected increasingly on his own identity as a Jew and assisted in efforts toward the establishment of the Hebrew University.As an internationalist opponent of war, and a German-speaking Swiss citizen whose renown was sealed by the Englishman Eddington's confirmation of relativity, Einstein mitigated postwar hostility toward German scholars. Correspondence with family and friends documents his divorce, remarriage to his cousin, and his closeness to his two sons. Notwithstanding evidence in newly uncovered material concerning efforts to lure Einstein back to Switzerland, and also to the Netherlands, Einstein, entertaining high hopes for the young Weimar Republic, remained in Berlin. This volume reveals new facets of Einstein as he constructively participated in German and European scientific, academic, and cultural life.

The first half of this volume presents a substantial amount of heretofore unavailable correspondence. From among family letters closed for twenty years after the death of Margot Einstein, who donated them to the Albert Einstein Archives in Jerusalem, the volume presents, for the first time, letters written by Einstein's sons, the adolescent Hans Albert and little Eduard, and numerous letters written by Einstein to his cousin and future second wife Elsa Einstein. Combined with newly available correspondence with his close friend Heinrich Zangger, this supplementary correspondence provides vivid and intimate details of Einstein's private life. It documents the emotional bonds to his family and friends; the severe deprivations caused by the war to family members in Berlin and Zurich; the fragile health of Mileva Einstein-Maric during these years of separation and divorce; the worries and joys of caring for the sons; and Einstein's views on German and international politics during this turbulent period. The second half finds Einstein full of optimism about Germany's new democracy.He vigorously promotes general relativity and the endeavors of other scientists toward its further confirmation. He responds to the rising interest in his work among philosophers, as attested by correspondence with M. Schlick, H. Reichenbach, R. Carnap, E. Cassirer, and H. Vaihinger. And yet he is embroiled in vociferous, politically tinged, public attacks on his theory of relativity. He considers leaving Berlin, which would have deprived the Weimar Republic of its most famous scientist. In many letters, colleagues, friends, and unknown admirers offer support. Einstein travels to Leyden, where he is appointed a visiting professor and where, in the circle of friends such as P. Ehrenfest, H. A. Lorentz, and H. Kamerlingh Onnes, he is involved in lively debates on issues related to quantum physics. He visits Oslo and Copenhagen, where he meets with N. Bohr, and receives invitations to the United States, anticipating his first visit to the New World in 1921.

This index volume provides quick access to the most authoritative compilation of documents and information concerning Einstein's work and correspondence for the first half of his life. It offers readers a Cumulative Index to the first ten volumes of the collected papers, the first complete bibliography of Einstein's scientific and nonscientific writings until 1921, and a succinct biographical time line. This volume is an invaluable research tool for delving into Einstein's written legacy; his interactions with colleagues, institutions, friends, and family; and his scientific, political, educational, and social activities. Volume 11 presents three important and unique bibliographies: the List of Writings, 1891-1921; the Einstein Bibliography, 1901-1921; and a Cumulative Bibliography and Index of Citations for Volumes 1-10. The List of Writings includes all of Einstein's manuscripts that remained unpublished by 1921, while the Einstein Bibliography includes documents that were republished during this period. The Cumulative Bibliography and Index of Citations lists all literature written by authors cited in at least one of the first ten volumes of the series.This volume also contains two complete lists of Einstein's correspondence up through 1920, and a Chronology of Einstein's life for the years 1879-1921. The first list presents the correspondence in chronological order, while the second list presents the correspondence in alphabetical order by correspondent. The indexes and bibliographies implicitly correct inconsistencies and errata across the different volumes. Other corrections are explicitly collected in a List of Errata for the first ten volumes of the series.

In this latest volume, Einstein's visible public persona is amply documented in his correspondence, honors and prizes, lectures and travels, articles, and the many solicitations asking him to join public initiatives. Einstein joins a Zionist fundraising mission led by Ch. Weizmann, and he visits the United States for the first time. Einstein travels to major cities, including New York, Boston, and Chicago, and he delivers his now famous Princeton Lectures. Scientific issues remain at the core of Einstein's preoccupations. Correspondence with N. Bohr, W. Bothe, P. Ehrenfest, H. Geiger, H. A. Lorentz, L. Meitner, and A. Sommerfeld records Einstein's interest in and contributions to the emerging modern quantum theory. He addresses conceptual problems, such as the fundamental nature of light and its emission mechanism, in a proposed experiment with canal rays. Einstein continues to engage in original research, other expert opinions, and patent applications. Throughout the year, Einstein navigates complex territory in his professional and personal life. He travels with his older son to Bologna, yet turns down repeated invitations to Munich. He mends his friendship with M.Born, but receives stinging criticism from F. Haber for traveling to the United States. He supports the nomination of Masaryk for a Nobel Peace Prize, travels to Amsterdam in order to intervene on behalf of Germany at the Paris reparations conference, and assists Russian physicists in their efforts to rebuild and develop Russian science. Einstein's letters reveal his Social Democratic political positions.

Every document in The Collected Papers of Albert Einstein appears in the language in which it was written, and this supplementary paperback volume presents the English translations of all non-English materials. This translation does not include notes or annotation of the documentary volume and is not intended for use without the original language documentary edition which provides the extensive editorial commentary necessary for a full historical and scientific understanding of the documents.

In April 1922, we find Einstein lecturing in Paris, engaged in reestablishing ties among scientists in former enemy nations. Meanwhile, back in Berlin, political tensions are rising. In June, the brutal murder of his friend, Germany's foreign minister, Walther Rathenau, heavily affects Einstein who, for a while, fears for his own safety and briefly contemplates leaving Berlin and abandoning academic life altogether. When only a few months later it is announced that he will be awarded the Nobel Prize, after more than a decade of nominations, Einstein is on a steamer heading from Europe to Japan. As we learn in this volume, although he knew in advance of the coming prize, he nevertheless embarked on his longest voyage yet. His travel diary, published here for the first time, recounts in poetic prose the hectic schedule on land, the contemplative rest at sea, and his musings on science, philosophy, and art during his first encounter with the Far East, Palestine, and Spain. Einstein's work and intense scientific exchanges--with N. Bohr, P. Ehrenfest, A. Sommerfeld, M. Born, and others--during these fifteen months result in remarkable publications and intellectual developments.A paper written with Ehrenfest shows with uncompromising clarity that the outcome of the recent Stern-Gerlach experiment could not be explained by either classical or quantum theory. In a similar vein, he analyzes the phenomenon of superconductivity. Clearly among the leading quantum theorists, he focuses on its conceptual bases, tirelessly proposing crucial experiments that could decide between classical and quantum physics. We also see foundational interests develop in his concerns with a unified field theory of electromagnetism and gravitation.

The more than one thousand letters and several dozen writings included in this volume cover the years immediately before the final formulation of new quantum mechanics. The discovery of the Compton effect in 1923 vindicates Einstein's light quantum hypothesis. Niels Bohr still criticizes Einstein's conception of light quanta and advances an alternative theory, but Walther Bothe and Hans Geiger perform a difficult experiment that decides in favor of Einstein's theory. At the same time, Satyendranath Bose sends a new quantum theoretical derivation of Planck's law to Einstein and he discovers what is now known as Bose-Einstein condensation. Einstein attempts to reformulate a unified theory of the gravitational and electromagnetic fields. In early November 1923, Einstein flees overnight to the Netherlands in the wake of threats on his life and anti-Semitic rioting in Berlin. He rejoins the International Committee on Intellectual Cooperation in June 1924, and supports the idea of a European union. He joins the board of governors of Hebrew University, which opens in April 1925, and celebrates the event in Buenos Aires while on a seven-week lecture tour of Argentina, Uruguay, and Brazil.During this period, he delivers lectures, meets with heads of state, visits major institutions, and attends receptions hosted by the local Jewish and German communities. He has a serious, but short-lived, falling out with his son Hans Albert and his first wife Mileva Maric-Einstein over how to invest part of the Nobel Prize money and he rescues his sister Maja and her husband from debt on their house. Einstein has a fourteen-month romantic relationship with his secretary, Betty Neumann, which he ends in October 1924.

In the almost one hundred writings and more than one thousand letters included in this volume, Einstein is revealed yet again as the consummate puzzler of myriad scientific problems as well as the invested participant in social and political engagements. He continues to explore the light quantum, whose reality is confirmed by new experiments, and to attempt to formulate a unified theory of gravitation and electromagnetism. He travels to South America, where he lectures widely on relativity, rejoins the International Committee on Intellectual Cooperation, and supports the idea of a European union. Einstein has a fourteen-month romantic relationship with his secretary, Betty Neumann, which ends in October 1924.

The past decade has seen a considerable surge of interest in historical and philo­ sophical studies of gravitation and relativity, due not only to the tremendous amount of world-wide research in general relativity and its theoretical and observational consequences, but also to an increasing awareness that a collaboration between working scientists, historians and philosophers of science is, in this field, partic­ ularly promising for all participants. The expanding activity in this field is well documented by recent volumes in this Einstein Studies series on the History of General Relativity as well as by a series of international conferences on this topic at Osgood Hill (1986), Luminy (1988), and Pittsburgh (1991). The fourth of these conferences, hosted by the Max Planck Institute for the History of Science, was held in Berlin from 31 July to 3 August 1995, with a record attendance of some 80 historians and philosophers of science, physicists, mathematicians, and as­ tronomers. Based on presentations at the Berlin conference, this volume provides an overview of the present state of research in this field, documenting not only the increasing scope of recent investigations in the history of relativity and gravitation but also the emergence of several key issues that will probably remain at the focus of debate in the near future. RELATIVITY IN THE MAKING The papers of this section deal with the origins and genesis of relativity theory.

This volume explores the interplay between mathematical and physical research and the interactions of twentieth-century scientists within their academic communities. Beginning with Einstein’s general theory of relativity, the authors investigate a series of dramatic discoveries and rival theories in physics that influenced the development of modern differential geometry. Other sections recount the numerous methods, like the resurgence of Weyl geometry, used by geometers to solve the problems revealed by those same innovations in space-time physics. The effect of general relativity on astronomy is also addressed, namely how astronomers worked through new theories like inflationary cosmology and Phoenix models.By including recent historical research and coupling this work with many disciplines’ unique perspectives, this text provides a rich picture of general relativity and cosmology over the course of the twentieth century. The increased study on the documentation of Einstein’s early scientific work has clarified the history of science for that time and profoundly altered the way scientists view their own work, as this interdisciplinary volume demonstrates.

This volume offers an integrated understanding of how the theory of general relativity gained momentum after Einstein had formulated it in 1915. Chapters focus on the early reception of the theory in physics and philosophy and on the systematic questions that emerged shortly after Einstein's momentous discovery. They are written by physicists, historians of science, and philosophers, and were originally presented at the conference titled Thinking About Space and Time: 100 Years of Applying and Interpreting General Relativity, held at the University of Bern from September 12-14, 2017. By establishing the historical context first, and then moving into more philosophical chapters, this volume will provide readers with a more complete understanding of early applications of general relativity (e.g., to cosmology) and of related philosophical issues. Because the chapters are often cross-disciplinary, they cover a wide variety of topics related to the general theory of relativity. These include:Heuristics used in the discovery of general relativityMach's PrincipleThe structure of Einstein's theoryCosmology and the Einstein worldStability of cosmological modelsThe metaphysical nature of spacetimeThe relationship between spacetime and dynamicsThe Geodesic PrincipleSymmetriesThinking About Space and Time will be a valuable resource for historians of science and philosophers who seek a deeper knowledge of the (early and later) uses of general relativity, as well as for physicists and mathematicians interested in exploring the wider historical and philosophical context of Einstein's theory.

This volume collects reflections on the role of philosophy in case studies in the history of science. Case studies have played a prominent role in recent history and philosophy of science. They have been used to illustrate, question, explore, or explicate philosophical points of view. Even if not explicitly so, historical narratives are always guided by philosophical background assumptions. But what happens if different philosophies lead to different narratives of the same historical episodes? Can historical case studies decide between competing philosophical viewpoints? What are the criteria that a case study has to fulfill in order to be philosophically relevant? Bringing together leading practitioners in the fields of history and philosophy of the physical and the life sciences, this volume addresses this methodological problem and proposes ways of rendering explicit philosophical assumptions of historical work.

This volume collects reflections on the role of philosophy in case studies in the history of science.

This Volume has three sections, General Relativity, Epistemological Issues, and Quantum Mechanics. The core of the first section is Hilberts two semester lecture course on ?The Foundations of Physics? (1916/17). This is framed by Hilberts published ?First and Second Communications? on the ?Grundlagen der Physik? (1915, 1917). The section closes with a lecture on the new concepts of space and time held in Bucharest in 1918. The epistemological issues concern the principle of causality in physics (1916), the intricate relation between nature and mathematical knowledge (1921), and the subtle question whether what Hilbert calls the ?world equations? are physically complete (1923). The last section deals with quantum theory in its early, advanced and mature stages. Hilbert held lecture courses on the mathematical foundations of quantum theory twice, before and after the breakthrough in 1926. These documents bear witness to one of the most dramatic changes in the foundations of science.

The first part of volume 4 documents Hilbert’s efforts in the period 1898-1910 to base all known physics (including thermodynamics, hydrodynamics and electrodynamics) on classical mechanics. This period closes with a lecture course ‘Mechanik der Kontinua’ (1911), in which Hilbert considers the consequences of the new principle of special relativity for our understanding of physics. The second part starts with the lecture course ‘Kinetische Gastheorie’ (1911/12), which introduces a new approach to problems of statistical physics. The lecture course ‘Molekulartheorie der Materie’ (1913) deals with a topic that was of great importance to Hilbert, returning to it repeatedly. The last lecture course contained in this volume, ‘Statistische Mechanik’ (1922) presents a very perceptive comparison of the different approaches of Maxwell, Boltzmann, Gibbs etc. to the foundational problems of statistical physics. It is a paradigm of logical analysis and conceptual clarity.
