Parity nonconservation

Interview with Janice Button-Shafer, retired American physicist. Button-Shafer recounts her childhood in the Boston area, where her father worked as an engineer. She recalls the influence of her father on her interests in music, math and physics. Button-Shafer discusses her decision to study Engineering Physics at Cornell University, despite it being very uncommon for women to go into science. She discusses her summer jobs at MIT, Cornell Aeronautical Lab and Oak Ridge, as well as her experience writing for The Cornell Engineer magazine. Button-Shafer recounts her Fulbright Fellowship in Germany at the Max Planck Institute in Gottingen, focusing on neutron physics. She reflects on the political landscape during this time and how it affected science in Europe. Button-Shafer then recounts her decision to attend Berkeley for graduate school where she completed her thesis on parity violation while teaching courses such as quantum mechanics. She describes her research at the time at Lawrence Berkeley Lab and SLAC and discusses her work on thermonuclear energy and fusion reactors. She then turns to her move to University of Massachusetts Amherst and her eventual retirement and continuation of work at SLAC. Button-Shafer also talks about her marriage to mathematician John Shafer and the challenges of raising three children, one of whom battled cancer, during her demanding career as a scientist. Throughout the interview, Button-Shafer shares numerous anecdotes about the struggles of being a woman in a male-dominated field, including the discrimination and misogyny she endured throughout her career. She shares many stories of famous physicists she worked with over the years, including Owen Chamberlain, Emilio Segre, Luis Alvarez, Karl Heinz Beckhurts, and Edward Teller. Button-Shafer also shares her passion for the history of physics and relays many of her favorite historical tidbits involving scientists such as Lise Meitner, Marie Curie, Werner Heisenberg, and others. Her love of chamber music and classical music also comes up throughout the interview, as she reflects on her various musical accomplishments.

Interview with Steven Chu, former United States Secretary of Energy and current Professor of Physics and Professor of Molecular and Cellular Physiology in the Medical School at Stanford University. Chu begins by taking us through his changing research interests across his time at Berkeley, Bell Labs and Stanford, and then recounts the beginnings of his interest in climate change in the early 2000s. He talks about his work advising companies who are working on climate change solutions such as carbon capture, and he gives an overview of the research and action being taken around renewable energy sources. Chu then goes back in time and recounts the story of his family, starting with his grandfather in China who emphasized education for all his children. Growing up in Nassau County, Chu describes feeling like a “disappointment” in his family because he didn’t go to an Ivy League school and instead completed his undergraduate studies in math and physics at the University of Rochester. Chu discusses his decision to attend Berkeley for grad school and meeting his advisor Eugene Commins, who was working on weak interactions. Then Chu recounts his transition to Bell Labs and describes the laser work going on there at the time, as well as his burgeoning interest in beta decay experiments. He talks about his research surrounding laser cooling and explains his decision to move to Stanford after Bell. Chu remembers his experience winning the Nobel Prize and accepting the position as director of Lawrence Berkeley National Lab. Chu ends the interview with stories from his time as Secretary of Energy under the Obama administration, such as his experiences with the Deepwater Horizon oil spill, setting up the DOE Loan Program Office, and his international work on climate change.

In this interview, Lee Pondrom, Professor of Physics Emeritus at the University of Wisconsin, Madison, recounts his childhood in Dallas, San Antonio and Houston and describes his early interest in science. He explains his motivations to attend Southern Methodist University, where he pursued a degree in physics. Pondrom discusses his graduate work at the University of Chicago where the long-range influence of the Manhattan Project remained strong, even in the early and mid-1950s. He describes his summer research work at Los Alamos, and his thesis research on cyclotrons and pi mesons under the direction of Albert Crewe and Uli Kruse. Pondrom conveys the feeling of excitement at the discovery of parity violation while he was a graduate student, his postdoctoral work on the Nevis cyclotron while at Columbia, and he describes his Air Force service after he defended his dissertation. He describes the opportunities leading to his tenure at the University of Wisconsin and a research agenda that included long-term projects at the Chicago cyclotron, and at Fermilab and at Argonne. Pondrom discusses his contributions to CP violation, hyperon decay and how computers have been useful over the course of the career. He describes the origins of Fermilab and his experiences at Madison during the student unrest during the late 1960s, where bombers targeted science buildings. Pondrom discusses the significance of the E8 experiment as an extension of the Garwin-Lederman experiment and the origins of the Tevatron project. He explains the ups and downs of U.S. high energy physics during the SSC years and he surmises what would be known now in particle physics had the SSC been completed. At the end of the interview, Pondrom describes his extensive collaborations in Russia and his study of Soviet-era physics, including his work on Stalin’s nuclear diplomacy.

Focused interview deals with Garwin's childhood and schooling at Case and University of Chicago; his time at Chicago and interaction with Fermi. Majority of interview is on Garwin's work in designing the H-bomb and consulting work at Los Alamos in 1950-51. Recollections interspersed with technical details of design and apparatus. Discussion of recent 'discovery' of interview with Edward Teller in 1979 by George Keyworth that gives credit for H-bomb design to Garwin; Teller and Ulam's relation. Last part of the interview deals with Garwin's work in conjunction with Leon Lederman to confirm the non-conservation of parity in late 1956-early 1957.
