More than just a name. Physicist. Genius. Science pop star. Philosopher and humanist. Thinker and guru. On a par with Copernicus, Galileo or Newton. And: Albert Einstein – from Ulm! The most famous scientist of our time was actually born on 14th March 1879 at Bahnhofstraße 20 in Ulm. Albert Einstein only lived in the city on the Danube for 15 months. His extended family – 18 of Einstein’s cousins lived in Ulm at one time or another – were a respected and deep-rooted part of the city’s society, however. This may explain Einstein’s enduring connection to the city of his birth, which he described as follows in a letter to the Ulmer Abend- post on 18th March 1929, shortly after his 50th birthday: “The birthplace is as much a unique part of your life as the ancestry of your biological mother. We owe part of our very being to our city of birth. So I look on Ulm with gratitude, as it combines noble artistic tradition with simple and healthy character.” 8 9 The “miracle year” 1905 – Einstein becomes the founder of the modern scientific world view Was Einstein a “physicist of the century”? There‘s no doubt of that. In his “miracle year” (annus mirabilis) of 1905 he pub- lished 4 groundbreaking works along- side his dissertation. Each of these was worthy of a Nobel Prize and turned him into a physicist of international standing: the theory of special relativity, the light quanta hypothesis (“photoelectric effect”), Thus, Albert Einstein became the found- for which he received the Nobel Prize in er of the modern scientific world view. -
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. -
Math, Physics, and Calabi–Yau Manifolds
Math, Physics, and Calabi–Yau Manifolds Shing-Tung Yau Harvard University October 2011 Introduction I’d like to talk about how mathematics and physics can come together to the benefit of both fields, particularly in the case of Calabi-Yau spaces and string theory. This happens to be the subject of the new book I coauthored, THE SHAPE OF INNER SPACE It also tells some of my own story and a bit of the history of geometry as well. 2 In that spirit, I’m going to back up and talk about my personal introduction to geometry and how I ended up spending much of my career working at the interface between math and physics. Along the way, I hope to give people a sense of how mathematicians think and approach the world. I also want people to realize that mathematics does not have to be a wholly abstract discipline, disconnected from everyday phenomena, but is instead crucial to our understanding of the physical world. 3 There are several major contributions of mathematicians to fundamental physics in 20th century: 1. Poincar´eand Minkowski contribution to special relativity. (The book of Pais on the biography of Einstein explained this clearly.) 2. Contributions of Grossmann and Hilbert to general relativity: Marcel Grossmann (1878-1936) was a classmate with Einstein from 1898 to 1900. he was professor of geometry at ETH, Switzerland at 1907. In 1912, Einstein came to ETH to be professor where they started to work together. Grossmann suggested tensor calculus, as was proposed by Elwin Bruno Christoffel in 1868 (Crelle journal) and developed by Gregorio Ricci-Curbastro and Tullio Levi-Civita (1901). -
The Collaboration of Mileva Marić and Albert Einstein
Asian Journal of Physics Vol 24, No 4 (2015) March The collaboration of Mileva Marić and Albert Einstein Estelle Asmodelle University of Central Lancashire School of Computing, Engineering and Physical Sciences, Preston, Lancashire, UK PR1 2HE. e-mail: [email protected]; Phone: +61 418 676 586. _____________________________________________________________________________________ This is a contemporary review of the involvement of Mileva Marić, Albert Einstein’s first wife, in his theoretical work between the period of 1900 to 1905. Separate biographies are outlined for both Mileva and Einstein, prior to their attendance at the Swiss Federal Polytechnic in Zürich in 1896. Then, a combined journal is described, detailing significant events. In additional to a biographical sketch, comments by various authors are compared and contrasted concerning two narratives: firstly, the sequence of events that happened and the couple’s relationship at particular times. Secondly, the contents of letters from both Einstein and Mileva. Some interpretations of the usage of pronouns in those letters during 1899 and 1905 are re-examined, and a different hypothesis regarding the usage of those pronouns is introduced. Various papers are examined and the content of each subsequent paper is compared to the work that Mileva was performing. With a different take, this treatment further suggests that the couple continued to work together much longer than other authors have indicated. We also evaluate critics and supporters of the hypothesis that Mileva was involved in Einstein’s work, and refocus this within a historical context, in terms of women in science in the late 19th century. Finally, the definition of, collaboration (co-authorship, specifically) is outlined. -

Lost in the Tensors: Einstein's Struggles with Covariance Principles 1912-1916"
JOHN EARMAN and CLARK GL YMOUR LOST IN THE TENSORS: EINSTEIN'S STRUGGLES WITH COVARIANCE PRINCIPLES 1912-1916" Introduction IN 1912 Einstein began to devote a major portion of his time and energy to an attempt to construct a relativistic theory of gravitation. A strong intimation of the struggle that lay ahead is contained in a letter to Arnold Sommerfeld dated October 29, 1912: At the moment I am working solely on the problem of gravitation and believe 1 will be able to overcome all difficulties with the help of a local, friendly mathemat- ician. But one thing is certain, that I have never worked so hard in my life, and that I have been injected with a great awe of mathematics, which in my naivet~ until now I only viewed as a pure luxury in its subtler forms! Compared to this problem the original theory of relativity is mere child's play.' Einstein's letter contained only a perfunctory reply to a query from Sommerfeld about the Debye-Born theory of specific heats. Obviously disappointed, Som- merfeld wrote to Hilbert: 'My letter to Einstein was in vain . Einstein is evidently so deeply mired in gravitation that he is deaf to everything else? Sommerfeld's words were more prophetic than he could possibly have known; the next three years were to see Einstein deeply mired in gravitation, sometimes seemingly hopelessly so. In large measure, Einstein's struggle resulted from his use and his misuse, his understanding and his misunderstanding of the nature and implications of covariance principles. In brief, considerations of general covariance were bound up with Einstein's motive for seeking a 'generalized' theory of relativity; mis- understandings about the meaning and implementation of this motivation threatened to wreck the search; and in the end, the desire for general covariance helped to bring Einstein back onto the track which led to what we now recognize *Present address c/o Department of Philosophy, University of Minnesota, Minneapolis, Minn, U.S.A. -
The Fourteenth Marcel Grossmann Meeting on Recent Developments in Theoretical and Experimental General Relativity, Astrophysics
September 4, 2017 9:39 ws-procs961x669 MG-14 – Proceedings (Part D) D433 page 3372 3372 The renaissance of general relativity in Rome: Main actors, research programs and institutional structures Luisa Bonolis∗ Max Planck Institute for the History of Science, Berlin, Germany ∗E-mail: [email protected] Adele La Rana Sapienza University, Rome, Italy E-mail: [email protected] Roberto Lalli Max Planck Institute for the History of Science, Berlin, Germany E-mail: [email protected] We show that the revitalization of General Relativity (GR) in Rome during the 1960s was mainly shaped by the confluence of two different research programs centered around two authoritative figures: the first was the focusing of former Levi–Civita’s student Carlo Cattaneo on the mathematical problems of GR and the establishment of a research group in Rome; the second was sparked by the return in Italy of the astrophysicist Livio Gratton in 1960. We also argue that the material possibilities for a novel confluence between previously separated fields in the Roman environment was made possible by deep institutional changes and, especially, by the organizational choices and visions of Edoardo Amaldi who was leading the postwar reconstruction of Italian physics. Keywords: General relativity; relativistic astrophysics; Tullio Levi–Civita; Giuseppe Armellini; Enrico Fermi; Carlo Cattaneo; Edoardo Amaldi; Livio Gratton. The First Phase: The interwar period In the late 1960s, General Relativity (GR) definitely returned to the mainstream of physics, coming into focus in connection with major astrophysical discoveries and becoming an internationally visible, highly active field of research. In order to The Fourteenth Marcel Grossmann Meeting Downloaded from www.worldscientific.com better elucidate how this historical process — the so-called Renaissance of GR, as Clifford Will christened it — developed in Rome during the 1960s, it is necessary to put it in relation to the research and teaching of GR in the Roman institutional settings starting from the early 1920s. -

ICRANet seat in Nice (France). National Academy of Sciences of Armenia, which hosts the ICRANet seat in Yerevan (Armenia). (Above:) CBPF, which hosts the ICRANet seat in Rio de Janeiro. (Below:) The planned seat at Cassino da Urca (Brazil). II This brochure reviews some background facts concerning the founding of ICRANet and its current structures and then turns to the 2015 celebrations of the Year of Light and the ICRANet initiated International Relativistic Astrophysics Ph.D. program (the IRAP-PhD). It then addresses the birth of relativistic astrophysics following the first fifty years of the existence of general relativity plagued mainly by the absence of observational or experimental activity. Four events marked the onset of relativistic astrophysics: the discovery by Schmidt of the first quasar in 1962, of Scorpius X1 by Riccardo Giacconi in 1963, of the cosmic background radiation by Penzias and Wilson in 1964, and of pulsars by Jocelyn-Bell and Antony Hewish in 1967. These events led to a systematic development of the understanding of the four pillars of relativistic astrophysics: supernovae where observations of the CRAB Nebula are still relevant today, white dwarfs and neutron stars, black holes and their first identification in Nature in Cygnus X1 found by Riccardo Giacconi with the UHURU satellite based on the conceptual background developed by our group in Princeton, and finally the discovery of gamma ray bursts as the largest energy source delivered in the shortest time of any astrophysical phenomenon. -

Albert Einstein - Wikipedia, the free encyclopedia Page 1 of 27 Albert Einstein From Wikipedia, the free encyclopedia Albert Einstein ( /ælbərt a nsta n/; Albert Einstein German: [albt a nʃta n] ( listen); 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of general relativity, effecting a revolution in physics. For this achievement, Einstein is often regarded as the father of modern physics.[2] He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect". [3] The latter was pivotal in establishing quantum theory within physics. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. He Albert Einstein in 1921 realized, however, that the principle of relativity could also be extended to gravitational fields, and with his Born 14 March 1879 subsequent theory of gravitation in 1916, he published Ulm, Kingdom of Württemberg, a paper on the general theory of relativity.
