  • The Evil We Were Interested in Pushing Out
    To the Trustees: The article contained in this number of the Confi- dential Monthly Report was written by George V. Gray of our staff and is of such unusual interest that I am sure all the Trustees will want to read it carefully. Whether the release of atomic energy in the long run will result in good or evil for the race, no one can now say; but whatever the consequences, the Foundation and its related boards cannot escape their share of the responsibility, indirect as it may be. The atomic bomb is the result of influences which, for the most part uninten- tionally and unwittingly, we helped to set in motion, because we were interested in pushing out the boundaries of knowledge, It is a tragic irony that when men have been most successful in the pursuit of truth, they have most endangered the possi- bility of human life on this planet. The towering question which faces the world now is whether the new energies can be controlled. It is, I know, the hope of all of us that the Foundation may be able to make some contribution, however slight, to this end. Raymond B.

He has been labeled both warm and cold, friendly and condescending, affable as well as hurtful. Learning Sanskrit and cultivating the air of an aesthete, as a young professor he stretched the bounds of the scientist’s persona. Yet in the space of a decade, the otherworldly theorist was transformed into a political insider par excellence. His fellow scientists remembered him as a visionary and capable leader at Los Alamos, while his security hearing brought to light foolish mistakes in judgment and human relationships.

  • Distinguished Lecture Series in Physics and Astronomy Making an Impact
    University of South Carolina Department of Physics and Astronomy 2018 regularly exceeds 200 people, and for several lectures, we have had standing room only in the 500-seat performance hall located in the Darla Moore School of Business. In addition to presenting a public lecture, every visiting speaker is scheduled for a range of informal meetings or lunches with students, faculty, and researchers. Over the past year, we were treated to an especially distinguished slate of scholars. The president of the American Physical Society at the time, Dr. Laura Greene, explained the bizarre nature of high- temperature superconductivity. Dr. Greene is the Chief Scientist at the National High Magnetic Field Laboratory in Tallahassee, Florida and is also the Francis Eppes Professor of Physics at Florida State University. She illuminated the audience with a review of superconductivity and the behavior of this unconventional superconductivity. Next, the recipient of the 2014 Nobel Prize in chemistry, Dr. William E. Moerner, described the promise and challenges of super resolution microscopy. Dr. Moerner is the Harry S. Mosher Professor of Chemistry and a Professor of Applied Physics at Stanford University. He revealed how super resolution microscopy enabled single molecule imaging and what discoveries it may unveil in the future. 2017 Nobel laureate Dr. Barry Barish describes the unique signatures of the general Only four months after being awarded the 2017 Nobel Prize in theory of relativity contained in the first gravitational waves that were detected by physics, Dr. Barry Barish presented evidence for the first detection of Advanced LIGO in 2015. gravitational waves caused by merging black holes.

Soon thereafter, these so-called Feynman diagrams became a ubiquitous tool in theoretical elementary particle physics. In this contribution, I first briefly sketch how Feynman diagrams are used today, how they are most often interpreted and how their genesis is usually de- scribed, see sec.

    John A. Wheeler 1911–2008 A Biographical Memoir by Kip S. Thorne ©2019 National Academy of Sciences. Any opinions expressed in this memoir are those of the author and do not necessarily reflect the views of the National Academy of Sciences. JOHN ARCHIBALD WHEELER July 9, 1911–April 13, 2008 Elected to the NAS, 1952 John Archibald Wheeler was a theoretical physicist who worked on both down- to-earth projects and highly speculative ideas, and always emphasized the importance of experiment and observation, even when speculating wildly. His research and insights had large impacts on nuclear and particle physics, the design of nuclear weapons, general relativity and relativistic astrophysics, and quantum gravity and quantum information. But his greatest impacts were through the students, postdocs, and mature physicists whom he educated and inspired. Photography by AIP Emilio Segrè Visual Archives Photography by AIP Emilio Segrè He was guided by what he called the “principle of radical conservatism, ”inspired by Niels Bohr: Base your research on well-established physical laws (be conservative), but By Kip S. Thorne push them into the most extreme conceivable domains (be radical). He often pushed far beyond the boundaries of well understood physics, speculating in prescient ways that inspired future generations of physicists. After completing his PhD. with Karl Herzfeld at Johns Hopkins University (1933), Wheeler embarked on a postdoctoral year with Gregory Breit at New York University (NYU) and another with Niels Bohr in Copenhagen. He then moved to a three-year assistant professorship at the University of North Carolina (1935–1937), followed by a 40-year professorial career at Princeton University (1937–1976) and then ten years as a professor at the University of Texas, Austin (1976–1987).

  • The Weapons Program
    The Weapons Program AUTHORS Richard D. Baker (Plutonium) received a B.S. in chemical engineering from South Dakota School of Mines in 1936 and a Ph.D. in physical chemistry from Iowa State University in 1941. He came to Los Alamos from Chicago in 1943 to join the Chemistry and Metallurgy Division. His research and development on the preparation of plutonium and enriched uranium metal led to the patent for the production of plutonium metal on a multigram scale. Because of the importance and challenge of the materials research. he remained at Los Alamos after the war ended. He was a Group Leader in the Chemistry and Metallurgy Division from 1945 to 1956 and then became Leader of the newly formed Chemistry-Materials Science Division, which was involved in materials research and development for most of the Laboratory’s programs. He became Associate Director for Weapons in 1979 and Associate Director for National Security Programs a few months later. He retired from the Laboratory in May 1981 but continues serving the Laboratory as a consultant. Merle E. Bunker (Early Reactors) participated in the Manhattan Project as a chemical technician at Decatur. Illinois. where the diffusion-barrier tubes for the Oak Ridge gaseous diffusion plant were produced. He received his scientific training at Purdue University (B.S. in mechanical engineering. 1946) and Indiana University (Ph.D. in nuclear physics, 1950). He joined the Los Alamos staff in 1950. attracted here by the high reputation of the Laboratory, which he learned about from friends already working at Los Alamos. and by a strong desire to live in the West.
