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.

A translation of selected non-English texts included in Volume 15 is available in paperback. Since this supplementary paperback includes only select portions of Volume 15, it is not recommended for purchase without the main volume.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 select portions of non-English materials in Volume 15. 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.

This contributed volume is the result of a July 2010 workshop at the University of Wuppertal Interdisciplinary Centre for Science and Technology Studies which brought together world-wide experts from physics, philosophy and history, in order to address a set of questions first posed in the 1950s: How do we compare spacetime theories? How do we judge, objectively, which is the “best” theory? Is there even a unique answer to this question?The goal of the workshop, and of this book, is to contribute to the development of a meta-theory of spacetime theories. Such a meta-theory would reveal insights about specific spacetime theories by distilling their essential similarities and differences, deliver a framework for a class of theories that could be helpful as a blueprint to build other meta-theories, and provide a higher level viewpoint for judging which theory most accurately describes nature. But rather than drawing a map in broad strokes, the focus is on particularly rich regions in the “space of spacetime theories.”This work will be of interest to physicists, as well as philosophers and historians of science working with or interested in General Relativity and/or Space, Time and Gravitation more generally.

Pandemie und Klimakrise rufen die herausragende Rolle der Wissenschaft und des wissenschaftlichen Wissens für Informierung und Orientierung der Gesellschaft sowie für die Beratung der Politik bei der Ausrichtung praktischer Maßnahmen ins Bewusstsein. In diesem Zusammenhang wird die Frage virulent, weshalb der Wissenschaft diese herausgehobene Rolle zukommt. Dass diese Frage trotz der vielbeschworenen Autorität der Wissenschaft alles andere als trivial ist, zeigt sich daran, dass Wissenschaftsskepsis und Relativierung wissenschaftlicher Resultate bis hin zur Wissenschaftsleugnung Einfluss gewinnen, sobald es um konkrete Fragen der Ausrichtung gesellschaftlichen Handelns an der Wissenschaft geht. Wodurch ist also Vertrauen in die durch die Wissenschaft ermittelten Fakten, die in ihren Modellen entworfenen Szenarien und ihre Ratschläge an Gesellschaft und Politik gerechtfertigt? Weshalb soll man der Wissenschaft in besonderem Maße vertrauen und auf ihren Ratschlag hören?Insgesamt sollen die Beiträge des Buches Aufschluss darüber geben, wodurch die Vertrauenswürdigkeit der Wissenschaft in ihrer modernen Form gerechtfertigt ist und an welche Bedingungen ihre besondere Rolle in der Gesellschaft geknüpft ist. Was kann Wissenschaft für die Gesellschaft leisten und wo liegen die Grenzen ihrer orientierenden Rolle? Was heißt es „auf die Wissenschaft zu hören“ und was sind die Bedingungen dafür, dass Menschen in einer demokratischen Gesellschaft sich wissenschaftliche Erkenntnisse aneignen und sie als Richtschnur für ihr Handeln verwenden?
