Interview with Ian Hinchliffe, Senior Staff Emeritus at Lawrence Berkeley National Laboratory. Hinchliffe surveys the current state of play with the ATLAS collaboration. He recounts his childhood in northern England, and his interests and abilities in science that facilitated his admission to Oxford. Hinchliffe explains his decision to remain at Oxford for graduate school to work under the direction of Llewellyn Smith on deep inelastic scattering and he discusses his postdoctoral appointment at Berkeley Lab. He discusses his work in the theory group led by Geoff Chew and he explains the significance of QCD to reconcile calculations with experiments. Hinchliffe describes the opportunities that allowed him to stay at Berkeley Lab and the key developments of neutrino scattering. He discusses his involvement in supercollider physics and planning for the SSC and his tenure as leader of the theory group. Hinchliffe explains how Berkeley got involved in the ATLAS collaboration at CERN and George Trilling’s leadership of this effort, and he explains how CMS is both competitor and partner in the search for the Higgs and beyond. He conveys his feelings when the Higgs was discovered and how ATLAS has contributed to astrophysical research. At the end of the interview, Hinchliffe prognosticates on the future of CERN, and why he remains optimistic that the Higgs factory will push forward foundational discovery.

Interview with Edward Witten, Charles Simonyi Professor in the School of Natural Sciences at the Institute for Advanced Study. Witten discusses his current interests in quantum information theory in gravity, and he recounts his childhood in Baltimore and the influence of his father Louis Witten, who is a physicist. He describes his undergraduate education at Brandeis, where he majored in history, a brief stint working for the McGovern campaign, and a false start in graduate school to study economics before landing at Princeton to study first applied mathematics and then theoretical particle physics with David Gross. He describes the significance of deep inelastic scattering in the emergence of QCD and his earliest exposure to the ideas that would develop into string theory. Witten describes his postdoctoral appointment at Harvard to work with Steve Weinberg, Sidney Coleman, Shelly Glashow, and Howard Georgi. He discusses t’ Hooft’s success at solving the U(1) problem and his early work in supersymmetry by the time he joined the faculty at Princeton. Witten narrates the string revolution of 1984 and the early optimism that string theory would be able to describe the real world. He describes his involvement in topological quantum field theories and he explains his decision to move to the Institute from Princeton. Witten discusses his work with Nati Seiberg on N=2 super Yang Mills in four dimensions, the origins of M-theory in the 1994 string revolution, and the impact of Juan Maldacena’s work on AdS/CFT. He describes his collaboration with Seiberg on noncommutative geometry, his interest in the Langlands program, and the role of axions in string theory. Witten conveys the sense of optimism when the LHC turned on and the significance of Khovanov homology and Morse theory. He explains the need to revisit perturbative superstring theory and the possibility that the g-2 muon anomaly experiment at Fermilab will lead to new physics. At the end of the interview, Witten reflects on how little has been seen at the LHC after the Higgs discovery, and he expresses hope that string/M-theory and quantum gravity make meaningful contact during his lifetime.

He discusses some recent advances in his field, including new abilities to determine the 3D structure of proteins, and he explains his administrative duties as Scientific Director of the Institute. At the end of the interview, Leapman describes how the study of electrons has connected all of his research, and he discusses some of the challenges and opportunities he has confronted in his career as a physicist operating in a biologically-focused research environment.

In this interview, David Zierler, Oral Historian for AIP, interview Ad Bax, section chief in the Laboratory of Chemical Physics, at the NIH. Bax recounts his childhood in the Netherlands growing up on a farm and his undergraduate experience at the University of Delft. He describes his developing interest in nuclear magnetic resonance and the exciting theoretical opportunities that this new field presented. Bax discusses his graduate work with Ray Freeman at Oxford in NMR spectroscopy, and he explains the early role of computers on NMR research. He discusses the circumstances leading to his postdoctoral work at Colorado State University on solution and solid state NMR. Bax explains his initial work at the NIH using NMR to study protein structure.

Abhay Ashtekar, Evan Hugh Professor of Physics and Director of the Institute for Gravitation and the Cosmos at Penn State, is interviewed by David Zierler. Ashtekar recounts his childhood in the Indian state of Maharashtra, and discusses his early fascination with physics and the universe. He describes his undergraduate interests in general relativity and the opportunities that led to his enrollment at the University of Texas to join the Center for Relativity. Ashtekar discusses the culture shock when he arrived in Austin and Bob Geroch’s mentorship in quantum gravity, and his decision to follow Geroch to Chicago. He describes his interactions with Chandrasekar and his graduate research on quantum field theory in curved space-times and the asymptotic nature of space-time. Ashtekar discusses his postdoctoral appointment at Oxford to work with Roger Penrose, and he explains the moral origins of his commitment to making his field visible and therefore richer in opportunity for junior scholars. He explains his reasons to return to Chicago for a second postdoc, his decision to join the faculty at Syracuse, and a formative visiting appointment he had in Paris. Ashtekar describes the attraction in joining the faculty at Penn State, and his increasing focus on loop quantum gravity and the intellectual origins of the Ashtekar variable. He explains these developments as part of the broader effort to merge quantum mechanics and general relativity and the implications this will have on our understanding of the Standard Model. Ashtekar surveys the field of loop quantum cosmology and its relation to both inflation and string theory, and he conveys the enjoyment he felt with the detection of gravitational waves. At the end of the interview, Ashtekar explains why he does not like the phrase “theory of everything,” he reflects on the lessons he has learned from the luminaries who have mentored him, and he explains why the field still does not fully understand quantum mechanics.
