Ze’ev Rosenkranz – författare

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.

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.

Albert Einstein was initially skeptical and even disdainful of the Zionist movement, yet he affiliated himself with this controversial political ideology and today is widely seen as an outspoken advocate for a modern Jewish homeland in Palestine. What enticed this renowned scientist and humanitarian, who repeatedly condemned nationalism of all forms, to radically change his views? Was he in fact a Zionist? Einstein Before Israel traces Einstein's involvement with Zionism from his initial contacts with the movement at the end of World War I to his emigration from Germany in 1933 in the wake of Hitler's rise to power. Drawing on a wealth of rare archival evidence--much of it never before published--this book offers the most nuanced picture yet of Einstein's complex and sometimes stormy relationship with Jewish nationalism. Ze'ev Rosenkranz sheds new light on Einstein's encounters with prominent Zionist leaders, and reveals exactly what Einstein did and didn't like about Zionist beliefs, objectives, and methods.He looks at the personal, cultural, and political factors that led Einstein to support certain goals of Jewish nationalism; his role in the birth of the Hebrew University; his impressions of the emerging Jewish settlements in Palestine; and his reaction to mounting violence in the Arab-Jewish conflict. Rosenkranz explores a host of fascinating questions, such as whether Zionists sought to silence Einstein's criticism of their movement, whether Einstein was the real manipulator, and whether this Zionist icon was indeed a committed believer in Zionism or an iconoclast beholden to no one.

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.

Albert Einstein’s travel diary to the Far East and Middle EastIn the fall of 1922, Albert Einstein, along with his then-wife, Elsa Einstein, embarked on a five-and-a-half-month voyage to the Far East and Middle East, regions that the renowned physicist had never visited before. Einstein's lengthy itinerary consisted of stops in Hong Kong and Singapore, two brief stays in China, a six-week whirlwind lecture tour of Japan, a twelve-day tour of Palestine, and a three-week visit to Spain. This handsome edition makes available the complete journal that Einstein kept on this momentous journey.The telegraphic-style diary entries record Einstein's musings on science, philosophy, art, and politics, as well as his immediate impressions and broader thoughts on such events as his inaugural lecture at the future site of the Hebrew University in Jerusalem, a garden party hosted by the Japanese Empress, an audience with the King of Spain, and meetings with other prominent colleagues and statesmen. Entries also contain passages that reveal Einstein's stereotyping of members of various nations and raise questions about his attitudes on race. This beautiful edition features stunning facsimiles of the diary's pages, accompanied by an English translation, an extensive historical introduction, numerous illustrations, and annotations. Supplementary materials include letters, postcards, speeches, and articles, a map of the voyage, a chronology, a bibliography, and an index.Einstein would go on to keep a journal for all succeeding trips abroad, and this first volume of his travel diaries offers an initial, intimate glimpse into a brilliant mind encountering the great, wide world.

This volume covers one of the most thrilling two-year periods in twentieth-century physics, as matrix mechanics—developed chiefly by W. Heisenberg, M. Born, and P. Jordan—and wave mechanics—developed by E. Schrödinger—supplanted the earlier quantum theory. The almost one hundred writings by Einstein, of which a third have never been published, and the more than thirteen hundred letters show Einstein’s immense productivity and hectic pace of life.Einstein quickly grasps the conceptual peculiarities involved in the new quantum mechanics, such as the difference between Schrödinger’s wave function and a field defined in spacetime, or the emerging statistical interpretation of both matrix and wave mechanics. Inspired by correspondence with G. Y. Rainich, he investigates with Jakob Grommer the problem of motion in general relativity, hoping for a hint at a new avenue to unified field theory.Einstein falls victim to scientific fraud when, in a collaboration with E. Rupp, he becomes convinced that the latter’s experiments, aimed at deciding whether excited atoms emit light instantaneously (in quanta) or in a finite time (in waves), confirm a wave-theoretic explanation.While it was known that the teenage Einstein had been romantically involved with Marie Winteler in 1895, newly discovered documents reveal that his love for Marie was rekindled in 1909–10 while he was still married to Mileva Marić.The 1925 Locarno Treaties renew Einstein’s optimism in European reconciliation. He backs the “International manifesto against compulsory military service” and continues his participation in the League of Nations’ International Committee on Intellectual Cooperation. He remains intensely committed to the shaping of the Hebrew University in Jerusalem, although his enthusiasm for this cause is sorely tested.
