    Brief Newsletter from World Scientific February 2017 Exclusive Interview with 2003 Nobel Laureate One of the Top Condensed Matter Theorists and World Scientific Author Anthony Leggett Sir Professor Anthony James Leggett is a distinguished physicist who was awarded the Nobel Prize in Physics in 2003 for his pioneering contributions to the theory of superconductors and superfluids. He is currently a professor at the University of Illinois at Urbana-Champaign. Prof Leggett gave a presentation at the 2016 APS March Meeting in Baltimore, USA on “Reflections on the past, present and future of condensed matter physics”. In a phone interview, he shared with us some of his thoughts and further musings on the future of condensed matter physics.

Are there any recent you have a secure, tenured job (as I have been fortunate enough to discoveries that you would classify as paradigm shifts? have for the last few decades), then I think most certainly it’s better Well, if we go slightly outside the area of condensed matter physics to explore the unknown. But, of course, I appreciate that in the current as it has been conventionally defined, then, undoubtedly, any employment situation, people who have not got a tenured job need revolution which overthrew the view of quantum mechanics as a to think about their future. This may well be a rather strong pressure complete account of the world would, I think, certainly qualify as a to basically explore the known further.

Abstract: As quantum theory celebrates its 100th birthday, spectacular successes are mixed with outstanding puzzles and promises of new technologies. This article reviews both the successes of quantum theory and the ongoing debate about its consequences for issues ranging from quantum computation to consciousness, parallel universes and the nature of physical reality. We argue that modern experiments and the discovery of decoherence have have shifted prevailing quantum inter- pretations away from wave function collapse towards unitary physics, and discuss quantum processes in the framework of a tripartite subject-object-environment decomposition. We conclude with some speculations on the bigger picture and the search for a unified theory of quantum gravity. \...in a few years, all the great physical constants will ever, this involved an assumption so bizarre that even have been approximately estimated, and [...] the only oc- he distanced himself from it for many years afterwards: cupation which will then be left to the men of science will that energy was only emitted in certain finite chunks, or be to carry these measurement to another place of deci- \quanta".

He can see how the subject progressed and so is able to see which are the highest levels of development.

Volume IX, The Auditing Series, and Volume X, The Case Supervisor Series, contain Board Technical Bulletins that are part of the series. They are LRH data even though compiled or written by another.

  • 2019 Newsletter a Message from the Chair
    Quanta&Cosmos Department of Physics and Astronomy | 2019 Newsletter A Message from the Chair It is time for an update from the Department of Physics and Astronomy. The year 2019 marks some positive changes — we are onboarding three new tenure track faculty members as part of our effort to build a cluster in theoretical and computational physics. Computational techniques are playing an increasing role in physics and astrophysics research, helping one provide the missing link between analytical, numerical, and algorithmic approaches for solving fundamental problems in theoretical physics. The department has a long tradition in developing computational techniques to solve physics problems going back to the 1930s. Just 80 years ago (IEEE milestone), John Vincent Atanasoff, with his student Clifford Berry, designed and constructed the first electronic digital computer, the Atanasoff-Berry Computer, which included electronic switches, a capacitor array, and a moving drum memory to solve systems of linear equations. Today’s digital revolution was made possible by the early pioneers of computing, including Alan Turing, John von Neumann, Konrad Zuse, John Atanasoff, and many others, and it continues to enable and accelerate scientific research and our digital lifestyle of today. Clearly, past long-term investments in education and research have paid off. Our graduate and physics majors programs also received a boost this year with 17 incoming graduate students and 25 new physics majors. This brings our total numbers to 90 graduate students, 120 physics majors, and 27 postdoctoral associates. Having that many early career scientists in the department just starting their academic paths makes for an exciting learning/ research environment.

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. According to the characteristics of emergency repair in overhead transmission line accidents, a complexity quantification method for emergency repair scheme is proposed based on the entropy method in software engineering, which is improved by using group AHP (analytical hierarchical process) method and Petri net. Firstly, information structure chart model and process control flowchart model could be built by Petri net. Then impact factors on complexity of emergency repair scheme could be quantified into corresponding entropy values, respectively. Finally, by using group AHP method, weight coefficient of each entropy value would be given before calculating the overall entropy value for the whole emergency repair scheme.
