Devoret recounts his childhood in France where his father was a physician and his mother was a teacher. He describes his parents’ experiences during World War II and his early interests in many areas of science such as computers, artificial intelligence, and biology. Devoret explains some nuances of the French schooling system and how he followed an engineering track in his undergraduate studies before focusing on physics. He recalls pursuing his Master’s degree at Orsay University where he worked in a molecular physics lab, as well as the opportunity that led him to pursue a PhD while working in Anatole Abragam’s lab at the Atomic Energy Commission (CEA) in Saclay. Devoret talks about his thesis work on nuclear magnetic resonance in solid hydrogen. He then discusses his postdoc at Berkeley working with John Clarke on quantum tunneling and his subsequent return to Saclay where he eventually helped found the Quantonics Lab and later was named Director of Research at CEA-Saclay. Devoret recalls the circumstances around his move to Yale and his work with Steve Girvin. He reflects on several of his interest areas during this time, such as microwave reflectometry, nanofabrication, remote entanglement, and quantum computing. At the end of the interview, Devoret offers advice for how to avoid doing bad science, and he shares his recent interest in the popularization of science, particularly making quantum physics more accessible.

Interview with Sir Anthony Leggett, professor emeritus at the University of Illinois Urbana-Champaign (UIUC). Leggett begins with recollections from his childhood as the son of two schoolteachers. He discusses studying classics at Oxford and having minimal science or math education. Leggett explains that he contemplated pursuing graduate studies in philosophy, but he met a priest who taught him complex mathematics concepts, leading to his interest in physics. He describes obtaining his second undergraduate degree in physics from Oxford, as well as his graduate studies in theoretical condensed matter physics under Dirk ter Haar. Then Leggett recalls going to UIUC for a postdoc with David Pines and also to Japan to study with Takeo Matsubara. Leggett discusses his appointment at Sussex University and his shift from low temperature physics into quantum mechanics. He reflects on accepting the offer to move back to UIUC as the endowed MacArthur Chair, as well as what it was like to receive the call about winning the Nobel Prize. The interview ends with Leggett sharing advice for physics students and reflections on his time teaching in Ghana.

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 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 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.
