    Mici Teller Edward Teller Nick Metropolis Arianna Rosenbluth Marshall Rosenbluth An Interview vith Bernie Alder Bernie Alder 1997, from NERSC , part of the Stories of the Development of Large Scale Scientific Computing at Lawrence Livermore National Laboratory series. It is little known that THE algorithm was independently discovered by Bernie Alder, Stan Frankel and Victor Lewinson. Quoting Alder: ..we started out with a configuration, a solid like order configuration, and then jiggled the particles according to the pulse rate distribution. And that is, in fact, known now as the Monte Carlo Method—it was presumably independently developed at Los Alamos by Teller, Metropolis, and Rosenbluth. They actually got all the credit. My guess is we did it first at Cal Tech. It's not that difficult to come up with that algorithm, which, by the way, I think is one of, if not THE, most powerful algorithms Actually, In a footnote of the original paper by Metropolis et al. they credited Alder, Frankel and Lewinson on this, but this fact has been almost forgotten over the years. Furthermore Alder et al. did not give a general formulation for the algorithm but only a specialized version for hard spheres."

But with suitable conditions, e.g. low density and/or high temperature, electrons and ions will unbind and we obtain a plasma, a state of matter of which we became increasingly aware in the 20th century, and which pervades our universe near and far. There are also many applications of plasma physics: chip etching, TV screens, torches, propulsion, fusion (through magnetic or inertial confinement), astrophysics and space physics, and laser physics, to cite just a few. At the crossroads of electrodynamics, continuum physics, kinetic theory and nonlinear physics, plasma physics enjoys an abundance of riches. Actually, so much that we can only cover a fraction of its history in this limited volume. The history of plasma physics presented here covers mostly the period from 1950 to 2000. The issue is focussed both on fundamentals and on applications in controlled fusion through magnetic confinement, which in turn raises a host of fundamental and interesting questions in various areas.

Krebs Director, Office of Science U.S. Department of Energy 1000 Independence Avenue, S.W. Washington, D.C. 20858 Dear Dr. Krebs: The FESAC is pleased to be able to complete its response to your charge of October 9, 1998, in regard to … “leading a community assessment of the restructured program thus far, including recommendations for further redirection given projected flat budgets for fusion. With this assessment as background, I would like your recommendations as to the proof-of-principle experiments now under review, as well as your recommendations regarding the balance of the program between tokamak and non-tokamak physics, and between magnetic and inertial fusion energy. Working with the Office of Fusion Energy Sciences (OFES), please develop goals and metrics to use in making your recommendations. I would also welcome any other recommendations on program content, emphasis, or balance.” In discussion with Dr. N. A. Davies, Director of OFES, it was agreed to frame the sub-charges as: · Recommend a balance between MFE and IFE; · Recommend priorities in the MFE program; · Recommend priorities in the IFE program; and · Recommend a course of action for the three proof-of-principle (POP) proposals. During the past year there has been a considerable amount of activity which helped us reach our conclusions. The FESAC has visited a number of fusion sites and has heard extensive presentations on the program.

  • Harold Furth Was Born in Vienna, Austria, on January 13, 1930
    NATIONAL ACADEMY OF SCIENCES HAROLD P. FURTH 1930– 2002 A Biographical Memoir by T. KENNETH FOWLER Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. Biographical Memoirs, VOLUME 83 PUBLISHED 2003 BY THE NATIONAL ACADEMIES PRESS WASHINGTON, D.C. Dietmer R. Kraus HAROLD P. FURTH January 13, 1930–February 21, 2002 BY T. KENNETH FOWLER AROLD FURTH, AN AMERICAN giant in the world of fusion H research, died of heart failure in Philadelphia on February 21, 2002. He is buried in Princeton, where he spent most of his career at the Princeton University Plasma Physics Laboratory. Harold and I were collaborators in the pursuit of fusion energy, at Princeton in his case, at Livermore in mine. I am deeply saddened by his death and honored to be the one to record his career for the National Academy of Sciences. Harold was elected to the Academy in 1976 for his many achievements in plasma physics, the underlying discipline for the magnetic confinement approach to harness nuclear fusion energy. From graduate school days Harold’s forte was a deep understanding of magnetic fields, one of the areas in which plasma physics has enriched other disciplines, especially astrophysics. This served him well in his fusion career, in inventing new concepts and in understanding the ultimately successful tokamak involving in part currents created by the plasma itself. (“Tokamak” is a Russian acronym for a nuclear fusion device in which a plasma is confined in a toroidal tube by a magnetic field.) Harold’s main contribution to magnetic fusion research 3 4 BIOGRAPHICAL MEMOIRS was the tokamak fusion test reactor (TFTR), which he proposed in 1973, and which provided the first definitive demonstration of controlled fusion energy in 1993-94, pro- ducing 10 megawatts of fusion power for about one second in a plasma of equal parts deuterium and tritium, the DT fuel of future fusion reactors.

  • Marshall Rosenbluth
    FROM YEARNING TO BURNING Marshall Rosenbluth Possible broad-brush guidelines for “burning plasma” thinking December 6, 2000 The “yearn to burn” is well motivated. Most of us came into the fusion program with the dream of fusion energy. The dream persists. The US fusion program is now in a phase of broadening its science base. This is exciting and will certainly be profitable in terms of increasing chances of eventual success. Nonetheless we ultimately judge ourselves and are judged by others in terms of progress towards the fusion goal, both in understanding and in performance. From many talks with physics colleagues, as well as with students thinking about entering the field, I sense that the lack of performance progress and prospects in recent years has been a big factor in lowering our image to the external world. As we have realized for many years, the point at which science and the fusion energy goal converge is in a burning plasma experiment. It is there that we confront the unresolved issues of transport scaling, self-heating, burn control, and alpha physics, and also demonstrate that fusion energy is more than a fantasy. So let me begin from that point and suggest how we should approach the problem of a Next Step by setting down a few principles for discussion. 1-Is there a consensus that we know enough to propose a sensible experiment and at the same time that our knowledge is sufficiently imperfect that such an experiment is needed now? The Fermi paradigm that a good scientific experiment is one with a 50% chance of success may apply here, although for such a major venture the bar should no doubt be somewhat higher, at least for meaningful partial success.

  • Innovative Physicist Built Foundation for Modern Computer Science
    Innovative physicist built foundation for modern computer science March 19, 2021 Last surviving author of seminal paper on Metropolis algorithm dies By Madeline Whitacre, archivist-historian, National Security Research Center Arianna Wright Rosenbluth — former Los Alamos physicist and last surviving contributor to the seminal 1953 paper “Equation of State Calculations by Fast Computing Machines” on the first uses of what is now known as the Metropolis algorithm — passed away in December 2020 at age 93 from COVID-19 related causes. The Metropolis algorithm is a Markov chain Monte Carlo method that continues to be foundational in the modern world of computer science. Its applications today range from weather forecasting to climate change modeling, computer graphics, AI, economic analysis, and more. "The Metropolis algorithm enabled the application of the Monte Carlo method to a broad class of problems to which the original Monte Carlo techniques of Ulam and von Neumann were inapplicable. Its simplicity facilitated the eventual spread of its use throughout the quantitative sciences and engineering and even in the social sciences and humanities. It helped establish the Monte Carlo method as a 'go-to' method for understanding large, complex problems," said Jim Gubernatis of the Laboratory's T-4 group. Early years Growing up in Texas, Rosenbluth showed an affinity for science at an early age. She graduated with a bachelor’s in physics from Rice University at age of 18 and a master’s in physics from Radcliffe College a year later. In 1947, she began working on her doctorate at Harvard University, where she studied under John Van Vleck, who won the Nobel Prize in Physics in 1977.
