In this interview, Saul Perlmutter, Professor of Physics at UC Berkeley and Staff Scientist and senior faculty member at Lawrence Berkeley National Laboratory, discusses his life and career. Perlmutter shares that his research has not been slowed down by the pandemic by happy coincidence that he is currently focused on remote data analysis, and he recounts his childhood in Philadelphia where he was educated in Quaker schools. He discusses his early fascination with quantum mechanics and his decision to go to Harvard for his undergraduate education, where he cemented his interests in experimental physics. Perlmutter explains his decision to go to Berkeley for graduate school, where he worked in Buford Price’s group before Richard Muller became his graduate advisor. He discusses his early awareness of the cosmic microwave background and how he became involved with robotic searches for supernovae. Perlmutter describes the importance of NASA’s BITNET program as a way to connect observatory data worldwide to the computer systems at Berkeley, and he explains the intellectual and observational connections between the inflation, expansion, and acceleration of the universe. He discusses his postdoctoral research at Berkeley, and the circumstances leading to him becoming leader of the supernova group and how the DOE became more involved in astrophysics funding. Perlmutter explains the group’s focus on deceleration and he conveys the difficulties in scheduling telescope time to demonstrate spectroscopy proof of type Ia supernovae. He describes the origins of the SNAP satellite project, some of the early theoretical discussions on the nature of dark energy, and when, finally, his group secured long-term support from the Lab. Perlmutter narrates his first interactions with Brian Schmidt and Adam Riess and he describes the batch technique that could predict the discovery of supernovae, which vastly improved the efficiency of scheduling time on large telescopes. He explains the role of dark matter in speeding up the universe’s expansion, and he narrates the celebration with his team when he won the Nobel Prize and how he has chosen the use the political platform that comes with this recognition. Perlmutter discusses his interest in studying climate change, and at the end of the interview, he conveys his excitement about future observational discovery in astrophysics and cosmology.
Interview with Neal Lane, University Professor Emeritus and Professor Emeritus of Physics and Astronomy at Rice University, with an additional affiliation at the Baker Institute for Public Policy.

He explains the importance of direct communication with OMB, his relationship with Al Gore, and the key guidance offered by National Academy reports. Lane describes the LIGO effort from his vantage point at the NSF, and he explains his time as director of OSTP and Assistant to the President for Science and Technology. Lane discusses his work for PCAST and in the creation of the NNSA, and he describes returning to Rice after Gore lost the presidency, where the Baker Institute allowed him an environment to continue working in science and policy. At the end of the interview, Lane emphasizes the power of human connections as the foundation of all good science and policy endeavors.
Interview with John Spence, Richard Snell Professor of Physics at Arizona State University. Spence discusses his dual role as a Director of Science at NSF and his focus on research at the intersection of biology and physics. He recounts his childhood in Australia and his undergraduate education at Queensland University. Spence describes his graduate research on plasmons at Melbourne and the opportunities that led to his postdoctoral appointment at Oxford, where he worked with Mike Whelan and David Cockayne on quantifying atom arrangements in solids. He describes his decision to join the faculty at Arizona State, and the nascent field of high-resolution electron microscopy, which compelled him to write a book on the topic. Spence discusses his work on the structure of defects in superconductors and his collaborations with Bell Labs, and he explains the significance of the LCLS to his research. He describes the BioXFEL project, his work as part of the broader community of crystallographers, and the intellectual origins of the book "Lightspeed". At the end of the interview, Spence credits Michael Crow for bringing ASU to the forefront of so much innovation in science, and he reflects on how physics has never failed to surprise him.
Interview with Sally Dawson, Senior Scientist at Brookhaven National Laboratory and head of the high energy theory group there. Dawson recounts her childhood in Cleveland where her father was a rocket scientist for NASA. She describes her undergraduate education at Duke and how she came to focus on physics. Dawson cites the formative influence of Howard Georgi during her graduate work on proton decay and precision calculations at Harvard. She discusses her postdoctoral research in the theory group at Fermilab and her focus on some of the theoretical implications of the Tevatron project. Dawson surveys the research on supersymmetry and the Higgs mass at that time, and she explains her decision to join the scientific staff at Brookhaven where Mike Creutz and Bill Marciano were doing research of interest to her. Dawson discusses her long-term efforts to search for new physics beyond the Standard Model and she describes her book the Higgs Hunter’s Guide. She surveys what is known and unknown about the Higgs boson, and she discusses the g-2 muon experiment at Brookhaven and its relation to the current experiment at Fermilab. Dawson explains the value of the Snowmass process in achieving a high-level and future-oriented view of where the field is headed, and why the discovery of the Higgs demonstrated the overall accuracy of the Standard Model. She surveys the new questions that can be probed following the Higgs discovery and the complementary nature of neutrino precision measurements for this research. At the end of the interview, Dawson discusses her outreach efforts to emphasize that particle theory is not “dead,” why she sees advisory work as a vital service to the field, and why over the course of her career, experimentalists have provided more guidance to theorists, and not vice-versa.

In this interview Dr. Kenneth Watson, Dr. Richard Garwin, Dr. Curtis Callan, and Dr. Roy Schwitters participate in a roundtable discussion on the origins and early history of the JASON scientific advisory group. Watson, an emeritus from University of California San Diego Scripps Institution of Oceanography, discusses the early efforts of Charles Townes and Marvin Stern in forming JASON. Garwin, IBM Fellow Emeritus at the IBM Thomas J. Watson Research Laboratory of IBM, reflects upon IDA, the management organization that allowed for the formation of the JASON group. Callan, Professor of Physics at Princeton University, discusses the Charney Report and the sponsorship of Ari Patrinos of the Department of Energy, and his relationship with JASON. Schwitters, Regents Professor Emeritus from University of Texas Austin, and Garwin detail JASON’s 1980 report on tunnel detection. The group reflects upon the launch of Sputnik in 1957, and how it added urgency to the creation of JASON. Watson and Garwin discuss the early agenda of JASON and their focus on detection of missile launches, nuclear effects, and Nick Christofilos work with particle beam weapons. They discuss the involvement of JASON in the Vietnam War effort and how some members were targeted by protestors for their involvement. Watson and Schwitters reflect on the presence of Claire Max and the time it took to get more women involved in JASON in face of the traditional “boys club” atmosphere that was present in professional circles at the time. Garwin speaks about the development of the sonic boom report. Callen talks about his study on neutrino detection and the purpose of JASON in a post-Cold War era. He also discusses JASONs work on CHAMMP, Computer Hardware, Advanced Mathematics and Model Physics. The group describes the Human Genome project of the late 1990s. Schwitters and Garwin discuss how JASON can offer independent judgment in ways U.S. Intelligence agencies cannot, such as in 2009 when they were commissioned to study North Korean nuclear capability. Lastly, Watson speaks about how he believes GPS will become an important issue of study for JASON in the future, a point which is furthered by Garwin who also cites cybersecurity in general as a main focal point for JASON moving forward.
