Interview with Wit Busza, Francis L. Friedman Professor of Physics Emeritus at MIT. He recounts his birth in Romania as his family was escaping Poland at the start of World War II, and his family's subsequent moves to Cyprus and then to British Palestine, where he lived until he was seven, until the family moved to England. He describes the charitable circumstances that allowed him to go to Catholic boarding school, his early interests in science, and the opportunities that led to his undergraduate education in physics at University College in London, where he stayed on for his PhD while doing experiments at CERN working with Franz Heymann. Busza describes the development of spark chambers following the advances allowed by bubble chambers, and his thesis research using the Chew-Low extrapolation to calculate the probability that the proton is a proton plus a pi-zero. He describes meeting Martin Perl and the opportunities that led to his postdoctoral position at SLAC, which he describes in the late 1960s as being full of brilliant people doing the most exciting physics and where he focused on rho proton cross-sections. Busza describes meeting Sam Ting at SLAC which led to Busza's faculty appointment at MIT, where he discovered his talent for teaching. He discusses the complications associated with the discovery of the J/psi and his developing interest in relativistic heavy ion physics, the E178 project at Fermilab to examine what happens when high energy hadrons collide, and the E665 experiment to study quark propagation through nuclear matter. Busza describes the import of the RHIC and PHOBOS collaborations, and he discusses his return to SLAC to focus on WIC and SLD. He describes the global impact of the LHC and CERN, and his satisfaction at being a part of what the DOE called the best nuclear physics group in the country. In the last part of the interview, Busza reflects on the modern advances in atomic and condensed matter physics, which were inconceivable for him to imagine at the beginning of his career, he describes the considerations leading to his retirement, and why, if could re-live his career, he would think harder about being a theorist.

Interview with Dr. Elliot H. Lieb, professor of physics emeritus and professor of mathematical physics at Princeton University. Lieb opens the interview discussing the primary differences between physical mathematics and mathematical physics, and he outlines how modern mathematical ideas have been used in physics. The interview then looks to the past, to Lieb’s childhood and adolescence in New York City, where his passion for physics began. Lieb discusses his experience as a student at MIT, particularly his political involvement during the McCarthy Era. He also mentions his time working at Yeshiva University, and compares the political sentiment there to that at MIT and other universities around the United States. He talks about the work he was able to do abroad in the United Kingdom, Japan, and Sierra Leone, and about the lessons he learned from each of these experiences. Eventually, Lieb returned to Boston and joined the applied math group at MIT, while also working on the six-vertex ice model. In 1975, Lieb moved to Princeton, where he has collaborated with a number of scientists on a variety of topics and papers, including the 1987 AKLT Model (Affleck, Kennedy, Lieb, and Tasaki). The interview ends with Lieb looking to a future of continued experimentation and collaboration on the subjects that interest him most.
Interview with Matthew Fisher, professor of physics at UC Santa Barbara. Fisher recounts his early childhood in London as the son of a prominent physicist, and his upbringing in Ithaca where his father was on the physics faculty. He discusses his undergraduate experience at Cornell, where he started in engineering but gravitated toward physics, and he reflects on a conversation with a graduate student, which – more than any influene from his father or his brother, also a prominent physicist – sparked his interest. Fisher describes his initial graduate work at MIT, where he focused on experimental condensed matter research in the lab of Bob Birgeneau, before he transferred to the University of Illinois at Champaign-Urbana to re-focus on condensed matter theory, with a special interest in quantum mechanics under the direction of Tony Leggett. He explains the mental health issues he began to suffer from in graduate school, which extended into his postdoctoral, and then full time, work at IBM, until a psychiatrist prescribed him medication that essentially restored him to a state of mental health. Fisher describes the opportunities leading to his faculty appointment at UC Santa Barbara, and he discusses his newfound interests in high temperature superconductors, the fractional quantum Hall effect, and the localization of bosons. He discusses his ongoing interest in quantum mechanics, quantum spin liquids and quantum phase transitions, and he describes his long term collaboration with Charlie Kane. Fisher explains the singular advances Phil Anderson made to the field, and what supercomputing has allowed in the last twenty years that was not possible in the previous twenty years. He connects his mental health challenges with his recent interests in the concept of a quantum mind, or the possibility that the brain operates quantum mechanically. Fisher stresses that the field is nascent and that it is too early to tell if his preliminary ideas will be substantiated, and why a greater understanding of both evolution and the nature of consciousness is crucial to developing of this path of inquiry. He explains the implications of the notion of free will if the brain operates according to quantum processes, and he describes how this research may bear out experimentally.
Interview with Cherry Murray, Professor of Physics and Deputy Director of Research at Biosphere 2 at the University of Arizona. She describes some of the logistical challenges in managing Biosphere 2 during the pandemic, and she considers how current political and environmental crises perhaps make the research at Biosphere 2 all the more urgently needed. Murray reflects on how her work at the DOE has been an asset for Biosphere 2 and she recounts her early childhood, first in Japan and then Pakistan during her father’s postings for the Foreign Service. She describes her high school education in Virginia and then South Korea and the opportunities that led to her undergraduate admission at MIT, where she became close with Millie Dresselhaus. Murray explains her decision to remain at MIT for graduate work to conduct research in surface physics under the direction of Tom Greytak. She discusses her subsequent work at Bell Labs on negative positron work functions and where she rose to become Vice President, and she provides context for some of the exciting developments in superconductivity. Murray explains the circumstances and impact of the breakup of Bell Labs, and she reflects on her contributions on surface enhanced Raman scattering during her tenure. She discusses her work with Ernest Moniz, the circumstances of her being named Deputy Director for Science and Technology at Livermore Lab, she describes her tenure at Harvard and the development of the Division of Engineering and Applied Sciences, and her experiences as Commissioner of the BP Deepwater Horizon Oil Spill. At the end of the interview, Murray discusses the development of Biosphere 2, some of its early stumbles, and the vast research value it promises for the long term.
