    MAX-PLANCK-INSTITUT FÜR WISSENSCHAFTSGESCHICHTE Max Planck Institute for the History of Science PREPRINT 63 (1997) Giuseppe Castagnetti, Hubert Goenner, Jürgen Renn, Tilman Sauer, and Britta Scheideler Foundation in Disarray: Essays on Einstein’s Science and Politics in the Berlin Years ISSN 0948-9444 PREFACE This collection of essays is based on a series of talks given at the Boston Colloquium for Philosophy of Science, March 3 – 4, 1997, under the title “Einstein in Berlin: The First Ten Years.“ The meeting was organized by the Center for Philosophy and History of Science at Boston University and the Collected Papers of Albert Einstein, and co-sponsored by the Max Planck Institute for the History of Science. Although the three essays do not directly build upon one another, we have nevertheless decided to present them in a single preprint for two reasons. First, they result from a project that grew out of an earlier cooperation inaugurated by the Berlin Working Group “Albert Einstein.“ This group was part of the research center “Development and Socialization“ under the direction of Wolfgang Edel- stein at the Max Planck Institute for Human Development and Education.1 The Berlin Working Group, directed by Peter Damerow and Jürgen Renn, was sponsored by the Senate of Berlin. Its aim was to pursue research on Einstein in Berlin with particular attention to the relation between his science and its context. The research activities of the Working Group are now being continued at the Max Planck Institute for the History of Science partly, in cooperation with Michel Janssen, John Norton, and John Stachel.

  • Berlin Period Reports on Albert Einstein's Einstein's FBI File –
    Appendix Einstein’s FBI file – reports on Albert Einstein’s Berlin period 322 Appendix German archives are not the only place where Einstein dossiers can be found. Leaving aside other countries, at least one personal dossier exists in the USA: the Einstein File of the Federal Bureau of Investigation (FBI).1036 This file holds 1,427 pages. In our context the numerous reports about Ein- stein’s “Berlin period” are of particular interest. Taking a closer look at them does not lead us beyond the scope of this book. On the contrary, these reports give a complex picture of Einstein’s political activities during his Berlin period – albeit from a very specific point of view: the view of the American CIC (Counter Intelligence Corps) and the FBI of the first half of the 1950s. The core of these reports is the allegation that Einstein had cooperated with the communists and that his address (or “office”) had been used from 1929 to 1932 as a relay point for messages by the CPG (Communist Party of Germany, KPD), the Communist International and the Soviet Secret Service. The ultimate aim of these investigations was, reportedly, to revoke Einstein’s United States citizenship and banish him. Space constraints prevent a complete review of the individual reports here. Sounderthegivencircumstancesasurveyofthecontentsofthetwomost im- portant reports will have to suffice for our purposes along with some additional information. These reports are dated 13 March 1950 and 25 January 1951. 13 March 1950 The first comprehensive report by the CIC (Hq. 66th CIC Detachment)1037 about Einstein’s complicity in activities by the CPG and the Soviet Secret Service be- tween 1929 and 1932 is dated 13 March 1950.1038 Army General Staff only submit- ted this letter to the FBI on 7 September 1950.

  • Testing Einstein's General Theory of Relativity
    Astron. Nachr. / AN 326 (2005), No. 7 – Short Contributions AG 2005 Köln 1 Testing Einstein’s General Theory of Relativity GUDRUN WOLFSCHMIDT1 1Universität Hamburg, Schwerpunkt Geschichte der Naturwissenschaften, Mathematik und Technik, Bundesstraße 55, D-20146 Hamburg, Germany [email protected] Albert Einstein (1879–1955) had already proposed three possibilities for testing his General Theory of Relativity: • An additional perihel motion of Mercury (4300/century), which could not be explained by Newton’s theory of gravity; this was already known since 1850. • Deflection of light from the Sun (1.7500): The angular position of the stars are more distant from the Sun during a total solar eclipse than half a year later during the night. • Gravitational redshift of the Sun (2 × 10−6 of the wave length or 0.01 Å): The spectral lines of the Sun are shifted to the red by one millionth of the wave length of the light; this corresponds to a Doppler shift of 0.6 km/s. Many astronomers were sceptical against the new theory (ART), but Erwin Finlay-Freundlich (1885–1964) be- came interested in the ART since 1913 and tried to verify the theory empirically. He started an solar eclipse expedition in 1914 with the help of the Academy of Sciences which was not successful due to the outbreak of World War II. Karl Schwarzschild (1873–1916) tried to measure the redshift in the solar spectrum in 1913–1914 in the Astrophysical Observatory Potsdam. From these experiments it was clear that results could only be reached with much larger instruments. Arthur S.

  • The Einstein Tower, Potsdam, Germany
    Case Study 12.5: The Einstein Tower, Potsdam, Germany Gudrun Wolfschmidt and Michel Cotte Presentation and analysis of the site Geographical position: Telegrafenberg 1 , 14473 Potsdam, Germany. Location : Latitude 52º 22´ 44˝ N, longitude 13º 3´ 50 E˝. Elevation 87m above mean sea level. General description: The Einstein Tower, designed by the Berlin architect Erich Mendelsohn (1857–1953) and built in the early 1920s, is both an astrophysical observatory and a masterpiece of the history of modern architecture in Germany. Brief inventory : • The tower itself is 20m high. It was constructed between 1920 and 1922, but owing to a lack of modern construction materials after World War I, the tower had to be built with bricks instead of reinforced concrete. As a protection against the wind and heating, a wood- en structure was added on the inside of the tower, and this supports the objective lens. • The instrumentation was installed in 1924. The dome is 4.5 m in diameter and contained the two 85 cm-coelostat mirrors. The lens of 60 cm aperture and 14.50 m focal length produced a solar image 14 cm in diameter. The company Zeiss of Jena was responsible for the instrumentation. • The cellar contained a room at constant temperature. Here, two high-resolution spectrographs produced solar spectra from red to violet with a length of 12 m. In 1925, a physical-spectrographic laboratory was constructed. This contained a spectral furnace as a comparison light source, an apparatus to produce an electric arc, a photoelectric Registration photometer, an electromagnet and an apparatus for the investigation of the hyperfine structure of emission lines.

    © Copyright, Princeton University Press. No part of this book may be distributed, posted, or reproduced in any form by digital or mechanical means without prior written permission of the publisher. INTRODUCTION TO VOLUME 10 This volume, presenting 465 items of correspondence, is divided into two parts. The first half of the volume presents 211 supplementary letters to the correspon­ dence already published in Volumes 5, 8, and 9 for the period May 1909 through April 1920. Of these, 124 letters, most of them written by Albert Einstein, originate from the bequest of family correspondence deposited at the Albert Einstein Archives at the Hebrew University in Jerusalem by Margot Einstein (1899–1986), who stipulated that the material remain closed for twenty years after her death. Sixty-six letters for this period were obtained from the Heinrich Zangger manu­ script collection of the Central Library in Zurich, where it was deposited by the es­ tate of Gina Zangger (1911–2005). Twenty-one additional letters from other repos­ itories are also included. The second half of the volume presents 254 letters as full text from among a total of 614 extant correspondence items for the period May through December 1920. The editors have sought to present those letters that are representative and signifi­ cant for understanding Einstein’s work and life. Correspondence that is not present­ ed as full text is abstracted and listed chronologically in the Calendar at the end of the volume. The letters for the years 1909 through 1920 presented in the first half of this vol­ ume provide the reader with substantial new source material for the study of Ein­ stein’s personal life and the relationships with his closest family members and friends.

    Lauren MacKenzie Diagramming: Form Body Technique Space EVDA 621 E i n s t e i n T o w e r FORM - EINSTEIN TOWER grid represents single uniform Erich Mendelsohn, architect of the Einstein incoming light beam Tower, took inspiration from Einstein’s theory of relativity were light bends around objects due to imposed gravitational forces. Mendelsohn envisioned a new monolithic concrete tower which aimed to streamline exteriors with organically flowing interiors that defied traditional structural law (Pearson, 2001). The challenge was to still have the building function as a working observatory while not sacrificing the desired form. “Mendelsohn did not deny his ignorance regarding the practical aspects of a working observatory and was open to constructive criticism” (Hentschel, 1997, p. 55). Mendelsohn spoke often with his close friend Erwin Freundlich, an astronomer/ Einstein’s assistant, about how the building had to functionally be able to perform. After learning that the form, mostly layout, of the interior tower and subterranean floors was fixed in size and dimension due to the requirements of a working observatory, Mendelsohn shifted his focus to the rest of the building which was fair game for him to design. The exterior Expressionist architecture that emerged was seen to be unusual and “a little capricious… the stylistic language [did] not in any way suit the other buildings of the Astrophysical Institute” (Hentschel, 1997, p. 62) but due to the political situation of Germany post WWI, the Nation was in a hurry to build a monument in Einstein’s honour. “Thanks to the runaway inflation rate, such reservations about the design were briskly swept aside by decree at the highest cabinet levels, so as not to delay start of construction” (Hentschel, 1997, p.
