Princeton University Press, the Einstein Papers Project at California Institute of Technology, and the Albert
Einstein Archives at the Hebrew University of Jerusalem, are pleased to be publishing the latest volume in the massively authoritative Einstein Papers Project THE COLLECTED PAPERS OF ALBERT EINSTEIN: Volume 13: The Berlin Years: Writings & Correspondence, January 1922—March 23, Documentary Edition on September 25, 2012. When in the fall of 1922 it was announced that Albert Einstein had won the Nobel Prize in Physics, after more than a decade of nominations, Einstein was on a steamer headed for Japan. Although he was unofficially made aware of the upcoming award, he decided to leave Berlin, and makes no mention of the award in his detailed and poetic Travel Diary of his trip to the Far East, Palestine, and Spain, published here in its entirety for the first time. Together with a correspondence of 1,000 letters—most of which were never published before—with numerous colleagues, friends, and family members, the volume presents a rich trove of documents, central to understanding this period in Einstein’s life and work, heavily marked by the assassination of Germany’s foreign minister, his friend Walther Rathenau. As Einstein himself professed, the trip was an escape from the tense atmosphere in Berlin and rumored threats against his own life, as well as the fulfillment of his long-held desire to visit Japan.
Aside from his personal and political activities documented here, among which are his visit to Paris and his involvement in the League of Nations, Einstein was still heavily engaged in major current issues in theoretical physics. Thus, from among the thirty-six writings covering these fifteen months, a paper on the Stern-Gerlach experiment, written with Paul Ehrenfest, shows with uncompromising clarity that the experiment posed a problem that could not be solved by contemporary quantum theory and anticipates, in a sense, what later would become known as the quantum measurement problem. In relativity theory, Einstein continued to be concerned with its cosmological implications, and with the extent to which Mach’s principle would be vindicated in special solutions. He also began to investigate the possibilities and restrictions that relativity implied for a unified field theory of the gravitational and electromagnetic fields. During periods of leisure on board the steamer on his return trip from Japan, he completed a paper which further developed Arthur S. Eddington’s recent reinterpretation of relativity as being based solely on the concept of the so-called affine connection.
THE COLLECTED PAPERS OF ALBERT EINSTEIN
Diana Kormos Buchwald, General Editor
THE COLLECTED PAPERS OF ALBERT EINSTEIN is one of the most ambitious publishing ventures ever undertaken in the documentation of the history of science. Selected from among more than 40,000 documents contained in the personal collection of Albert Einstein (1879-1955), and 20,000 Einstein and Einstein-related documents discovered by the editors since the beginning of the Einstein Papers Project, The Collected Papers will provide the first complete picture of a massive written legacy that ranges from Einstein’s first work on the special and general theories of relativity and the origins of quantum theory, to expressions of his profound concern with international cooperation and reconciliation, civil liberties, education, Zionism, pacifism, and disarmament. The series will contain over 14,000 documents and will fill close to thirty volumes. Sponsored by the Hebrew University of Jerusalem and Princeton University Press, the project is located at and supported by the California Institute of Technology, and will make available a monumental collection of primary material. The Albert Einstein Archives is located at the Hebrew University of Jerusalem.
ABOUT THE SERIES
Thirteen volumes covering Einstein’s life and work up to his forty-fourth birthday have so far been published. They present more than 300 writings and 5,000 letters written by and to Einstein. Every document in The Collected Papers appears in the language in which it was written, while the introduction, headnotes, footnotes, and other scholarly apparatus is in English. Upon release of each volume, Princeton University Press also publishes an English translation of previously untranslated non-English documents.
