Schrodinger Centenary
At the Conference at London's Imperial College in April marking the centenary of the birth of Erwin Schrodinger — Schrodinger's daughter Ruth Braunizer with Austrian theorist Walter Thirring, who celebrated his 60th birthday this year (see page 29). Schrodinger centenary The centenary of the birth of poly math Erwin Schrodinger was marked by a suitably multidiscipli- nary conference in April at Lon don's Imperial College, reflecting the impact of the man's work on physics, chemistry, molecular biol ogy and the history and philosophy of science. Born in Vienna, Schrodinger had positions at Zurich, Berlin, Graz and Vienna but stayed longest in Dublin. E. T. S. Walton, from Dub lin, and the senior of the many Nobel laureates at the meeting (he shared the 1951 award with John Cockcroft) delightedly maintained that the grandfather of particle physics, J. J. Thomson, would have scorned modern theoretical ideas. Undeterred, Abdus Salam sum marized today's viewpoint while Steven Weinberg and Alexander Polyakov sketched the possibilities of unified 'string' theories. C. N. Yang drew attention to a 1922 Schrodinger paper (predating the famous ones by several years) containing an embryo form of the path dependent phase factors so useful in modern gauge theory. In a grand finale, Linus Pauling illustrated the impact of the cele brated equation on molecular biol ogy. Although Schrodinger's fame rests on his equation, he was more an ideas man, claimed Pauling, who like Max Perutz, was never theless sceptical of the role of At the Schrodinger centenary meeting, Alexander Polyakov (left) covered ideas in string theory while cosmology benefited from Stephen Hawking.

Freeman Dyson
Freeman Dyson (center) with colleagues PREDRAG CVITANOVIĆ Freeman Dyson remembered by people who knew him: “an unusual visionary” Colleagues reflect on the life and work of the renowned physicist, who died last week. by Edward Witten, Dwight Neuenschwander, Harold Feiveson, Arthur Jaffe, and Elliott Lieb Mar 2, 2020 Freeman Dyson, who died on Feb 28 at the age of 96, was an intellectual giant and well-regarded as a physicist, mathematician and public intellectual—and also as a mentor, grandfather and friend. Technology Review asked a number of his colleagues to reflect on his life and work. These are some of the responses; more will be added in coming days. Edward Witten, Institute for Advanced Study WIKIMEDIA, OJAN Freeman Dyson made fundamental contributions to an incredibly wide variety of fields in physics and mathematics. Among physicists, Dyson is known most of all as one of the pioneers of quantum electrodynamics. In the 1920s, physicists had learned to describe ordinary matter via the strange and often counterintuitive theory known as quantum mechanics. Moreover, it was known that light comes in the form of individual particles, or “quanta,” known as photons. But attempts in those days to understand the quantum mechanics of light interacting with matter led to intractable difficulties. By the late 1940s, when research in fundamental physics resumed after World War II, advances in technology made it possible to do experiments testing the quantum- mechanical interactions of photons and electrons—creating a compelling need to develop a workable theory. Dyson, along with Hans Bethe, Richard Feynman, Julian Schwinger, and Shinichiro Tomanaga, was one of the pioneers who accomplished this.

Bell's Universe: a Personal Recollection
Bell's Universe: A Personal Recollection Reinhold A. Bertlmann1 1University of Vienna, Faculty of Physics, Boltzmanngasse 5, 1090 Vienna, Austria∗ My collaboration and friendship with John Bell is recollected. I will explain his outstanding con- tributions in particle physics, in accelerator physics, and his joint work with Mary Bell. Mary's work in accelerator physics is also summarized. I recall our quantum debates, mention some per- sonal reminiscences, and give my personal view on Bell's fundamental work on quantum theory, in particular, on the concept of contextuality and nonlocality of quantum physics. Finally, I describe the huge influence Bell had on my own work, in particular on entanglement and Bell inequalities in particle physics and their experimental verification, and on mathematical physics, where some geometric aspects of the quantum states are illustrated. PACS numbers: 03.65.Ud, 03.65.Aa, 02.10.Yn, 03.67.Mn Keywords: Bell inequalities, nonlocality, contextuality, entanglement, factorization algebra, geometry Dedicated to Mary Bell, John's lifelong companion. I. COLLABORATION WITH JOHN BELL In April 1978 I moved from Vienna to Geneva to start with my Austrian Fellowship at CERN's Theory Division. Already in one of the first weeks, after one of the Theoretical Seminars, when all newcomers had a welcome tea in the Common Room, I got acquainted with John Stewart Bell. I remember when he approached me straightaway, \I'm John Bell, who are you?" I answered a bit shy, \I am Reinhold Bertlmann from Vienna, Austria." \What are you working on?" was his next question and I replied \Quarkonium...", which was already a magic word since we immediately fell into a lively discussion about bound states of quark-antiquark systems, a very popular subject at that time, which continued in front of the blackboard in his office.

The Global and the Local: The History of Science and the Cultural Integration of Europe. nd Proceedings of the 2 ICESHS (Cracow, Poland, September 6–9, 2006) / Ed. by M. Kokowski. Juraj Šebesta * Triangle collaboration (1) Introduction In this contribution we would like to inform briefly about so called Triangle collaboration — collaboration between Central-European institutes in field of elementary particle physics. History of Triangle collab- oration is very nice example how connections between East and West started and developed in weighty time of divided Europe. (2) The beginnings of the collaboration: 1964–1967 First step to establishing contacts were done in 1964. One of the pioneers of this collaboration Prof. Walter Thirring jr. (Institute of Physics, Vienna University) informed me that his father Prof. Walter Thirring senior at that time disposed with money from Ford foundation and he used it for financial supporting of contacts with East European states. On the other hand in Czechoslovakia was in the late 1960´s more favourable situation for entering to relations with foreign institutions. Therefore it was possible to start regular contacts. So during Rochester conference on elementary particle physics in Dubna in 1964 Walter Thirring jr. had contacted his Slovak colleagues — theoretical physicists from Bratislava, namely Dr. Milan Petráš (Comenius University) and Dr. Mikuláš Blažek (Slovak Academy of Sciences). They have agreed to start contacts between Vienna and Bratislava. First concrete step was done in next year of 1965. It was invitation for Slovak colleagues to take part in Fifth International Winter School on Nuclear Physics in Schladming in February 1966.
