Delmer This is a collection of papers presented and photos taken at the La Jolla Physics Symposium held on September 6 - 8, 1985 in conjunction with a Reunion of the people associated with the Physics Department of the University of California at San Diego during the academic years of 1960 to 1965. Historical pictures of the campus and the first five years of graduate students also appear. Those were the founding and formative years of the Department. Several students from that time were asked to give talks on their work since leaving the UCSD. When possible, their thesis advisors introduced their talks, otherwise, someone who was familiar enough with them to make a few incisive remarks was asked to give an introduction. The Symposium opened with a talk that described the beginning of the Department and closed with a panel discussion of the future of the University of California, the San Diego campus, as well as the Physics Department. The response was positive: about thirty percent of all those identified as being associated with the Department in those early days came to the Symposium. The talks, which were informal because of the broad range of subject matter and interests of the audience, showed an emotion that indicated that formation of the Department was a personal and moving experience for all involved. This was not a complete surprise; the choice of the first five years as the central theme, the limitation to those years, was made because after the mid '60's, the University had grown and the calcification mentioned by Greg Benford had begun to set in. But, the degree to which the feeling was universal and deep could not have been known beforehand. This remark is not just sentimentality. As Keith Brueckner describes, the University was started from the top down, from research faculty to graduate students and in 1965, to undergraduate students. The beginning of the Department consisted of a small group located at Scripps Institution of Oceanography in La Jolla (hence the UCLJ of the logo). The small size and the accompanying closeness made the experience unique. Changes took place rapidly. As Karl Eckart once said, "It was not that things were so exciting then, but that things have been pretty dull ever since." The skit, Physics on the Beach -- Scape written by Mike Green, Arnie Sherwood, and others, included here after the papers, qualifies the excitement. The importance of the early days of the Department as a personal experience and a method of starting a University became evident at the Symposium. Remember that physicists have a strong tendency to be arrogant. Read these pages and see how suppressed the arrogance was in the people recalling the events; you will see that even the most self important were in awe of what they experienced. It was not originally intended to produce a Proceedings since the talks were to be informative rather than of iv archival value. But as a whole, they painted a picture of the nascence of an important entity and documented the technical strength of the Department. It is the importance of the composite, the whole of the talks and photographic record, that make these Proceedings of archival value. Nevertheless, this document is of most interest to those readers who were part of the first five years. Other readers will credit that the beginning was unique, but may question the importance and quality of the Department and its product, i.e., the graduates during the years 1960 - 1965. The best way to judge the quality of the graduates is to read this document and form your own opinion; the introductions and talks have many clues to help make a judgment. The reader who is not interested in the technical content can read the opening talk by Keith Brueckner which provides a candid view of the beginning of the Physics Department. For those who want a succinct answer, they should read Norman Kroll's thoughts included in the Panel Discussion. Those who are interested in how the products of those early days of the UCSD Physics Department view various social and physics problems can find the answers in the papers included here. If you want to know how the hard nosed handled international relations and the Soviet threat, read Skid Masterson. If you want to get his advice in a nutshell, just read the summary of his paper; you will find that his desideratum is exactly what is happening in international relations four years later (1989). If you want to see sheer power in the application of physics and the scientific method, read Bud Jacobson; see the attention to detail, to precision. Read between the lines to see the tremendous discipline required to carry out the project from beginning to end. And what about the sea? We started at SIO on the ocean and men are drawn to the sea. Read Prothero. For the reader who thinks that is all saccharin nostalgia, read his remarks about how tough it was, read what Dick Morse says to back him up. It was tough. The linear prediction of the percentage passing the Departmental Exam went through zero in 1964. The behavior of the students preparing for that exam was bizarre, at best. If you think science and scientists are all specialized, arcane; read Herb (Herby Baby) Bernstein's paper on efforts to simplify, to unify. That became part of a book. Or Tom O'Neil's paper on a pure electron plasma. The plasma

TOFE is the ANS Fusion Energy Division’s topical meeting on the Technology of Fusion Energy, and it meets every two years, alternating between being “stand alone” and being embedded in the larger, biannual ANS meeting. This year’s TOFE was embedded with the 2018 Winter ANS Meeting, which allowed us the opportunity to rub shoulders with the larger nuclear society and discuss issues that overlap between different parts of the society. For this meeting, a concerted effort led to new topics for sessions that we hadn’t tried before: • Privately funded fusion ventures (organized by Ales Necas of TAE Technologies); • Licensing and safety for advanced

According to his own words in his younger years he was a master of “involuntary tourism” , participating passively in German occupations in three countries: Austria, Belgium and Northern Italy. He attended grammar school in Vienna and then a technical school in Brussels. From 1940 - 1943 he worked in a patent attorney’s office in Milan. He used to say that - contrary to Albert Einstein in Berne - being on the other side of the fence he really had to work hard. When the Germans occupied Northern Italy Val, together with his mother, fled to Switzerland. October 2, 2006, Plenary CHIPP Meeting, PSI, K.

Since the dawn of the history of science from Copernicus (who took the details of Ptolemy, and found a way to look at the same construction from a slightly different perspective and discover that the Earth is not the center of the universe) and Galileo to the present, we (a hoard of talking monkeys who's consciousness is from a collection of connected neurons − hammering away on typewriters and by pure chance eventually ranging the values for the (fundamental) numbers that would allow the development of any form of intelligent life) have gazed at the stars and attempted to chart the heavens and still discovering the fundamental laws of nature often get asked: What is Dark Matter? ... What is Dark Energy? ... What Came Before the Big Bang? ... What's Inside a Black Hole? ... Will the universe continue expanding? Will it just stop or even begin to contract? Are We Alone? Beginning at Stonehenge and ending with the current crisis in String Theory, the story of this eternal question to uncover the mysteries of the universe describes a narrative that includes some of the greatest discoveries of all time and leading personalities, including Aristotle, Johannes Kepler, and Isaac Newton, and the rise to the modern era of Einstein, Eddington, and Hawking.

    Edoardo Amaldi 1908-89 Edoardo Amaldi, right, with Gilberto Bernar- dini at a CERN Council session in 1965. Edoardo Amaldi, one of the driving forces of European science and a pioneer of CERN, died on 5 Decem• ber. He began his career in the 1930s with Enrico Fermi in Rome, where he helped discover that slow neutrons were more readily cap• tured in target nuclei. After the premature death of Et- tore Majorana and the decision of Fermi and other prominent Italian physicists to emigrate in the 1930s, Amaldi took essential steps to maintain the spirit of Ital• ian physics.

    Toshiki Tajima List of Publications (4/02/2018) The search for citation numbers of the publications has been done using Google Scholar and Web of Science. Because of the search engines do slightly differently as well as the choice of key words chosen are slightly different, we find that though they show some general agrément with each other, tehre sometimes miss particular article citations all together. Thus, we should be aware that some of the publications are still unaccounted for by both of the search engines. (Google Scholar Citations are shown starting with Gxxx at the end of the publications that were counted based on search with the key words of ‘plasma physics’, ‘accelerators’, and ‘lasers’. The total number of citations: 23346; h-index: 71; i10-index 276 (as of 12/20/2017 Google Scholar). For those papers that missed with these key words, shown are by a diferent Google Scholar search on 5/16/11 with #yyy. (The numbers of citations are stopped written in below 20 or so).

  • QUANTUM FIELD THEORY from QED to the Standard Model Silvan S
    P1: GSM 0521571995C19 0521571995-NYE March 6, 2002 13:59 19 QUANTUM FIELD THEORY From QED to the Standard Model Silvan S. Schweber Until the 1980s, it was usual to tell the story of the developments in physics during the twentieth century as “inward bound” – from atoms, to nuclei and electrons, to nucleons and mesons, and then to quarks – and to focus on conceptual advances. The typical exposition was a narrative beginning with Max Planck (1858–1947) and the quantum hypothesis and Albert Einstein (1879–1955) and the special theory of relativity, and culminating with the formulation of the standard model of the electroweak and strong interac- tions during the 1970s. Theoretical understanding took pride of place, and commitment to reductionism and unification was seen as the most impor- tant factor in explaining the success of the program. The Kuhnian model of the growth of scientific knowledge, with its revolutionary paradigm shifts, buttressed the primacy of theory and the view that experimentation and instrumentation were subordinate to and entrained by theory.1 The situation changed after Ian Hacking, Peter Galison, Bruno Latour, Simon Schaffer, and other historians, philosophers, and sociologists of science reanalyzed and reassessed the practices and roles of experimentation. It has become clear that accounting for the growth of knowledge in the physical sciences during the twentieth century is a complex story. Advances in physics were driven and secured by a host of factors, including contingent ones. Furthermore, it is often difficult to separate the social, sociological, and political factors from the technical and intellectual ones. In an important and influential book, Image and Logic, published in 1997, Peter Galison offered a framework for understanding what physics was about in the twentieth century.
