Abstract

Interview with Thomas Witten, Homer J. Livingston Professor, Emeritus, in the Department of Physics, James Franck Institute. Witten recounts his childhood in Maryland, Utah, and then Colorado, as his father, a medical doctor moved jobs, and he describes his undergraduate experience at Reed College and where majored in physics and where he benefited from excellent attention from the professors. He discusses his graduate work at UC San Diego, where he was advised by Shang Ma working on two-dimensional charged Bose gas research, and he describes his postdoctoral research at Princeton to work with John Hopfield. Witten conveys the exotic nature of Ken Wilson’s ideas on renormalization during that time, and he explains the origins of soft matter physics as a distinct field and his work at Saclay before joining the faculty at the University of Michigan. He describes his subsequent research on pushing concepts of renormalization into polymers and related work on the Kondo effect. Witten explains his decision to join the research lab at Exxon, and he conveys Exxon’s emulation of Bell Labs as a place where he could pursue basic science within an industrial research lab, and where he could continue his work on polymers. He describes the downsizing of the lab and his decision to join the faculty at the University of Chicago, and his discusses his developing interests in buckyballs and capillary flow. Witten describes his affiliation with the James Franck Institute and its rich history, and he explains his current interests in granular materials, thin sheets, and colloidal rotation. At the end of the interview, Witten emphasizes the technological impact of fast video on soft matter physics and his interest in the physics of crumpling objects.

Abstract

In this interview, Paul Chaikin, Silver Professor of Physics at NYU, recounts his childhood in Brooklyn and he describes his early interests in math and science and his education Stuyvesant High School. He discusses his undergraduate education at Caltech, he conveys how special it was to learn from Feynman and Pauling, and he explains the fields that would go on to form his area of specialty, soft matter physics. Chaikin explains his reasoning to pursue a graduate degree with Bob Schrieffer at Penn, where he did his thesis research on the Kondo effect in superconductors. He describes his first postgraduate work at UCLA where he developed an expertise in thermoelectric power, and he describes the intellectual and technological developments that paved the way for the creation of soft matter physics as a distinct field. Chaikin explains what it would take to solve the many-body problem of nonequilibrium phenomena, and he describes the delicate nature of collaborating with biologists while ensuring they don’t overtake the field. He discusses his joint appointment with Penn physics and the research laboratory at Exxon, and he explains his move to Princeton, which was just starting to develop a program in soft matter physics. Chaikin describes the famous experiment that discovered that M&M shapes (ellispoids) provided the most efficient and minimal negative space in packing applications, and he explains his decision to join the faculty at NYU. At the end of the interview, Chaikin reflects on some of the remaining mysteries in the field, and he describes his interest in pursing research on self-assembly among soft condensed matters.

Abstract

In this interview Harry Deckman, recently retired as Senior Scientific Advisor at ExxonMobil Corporate Strategic Research, explains the many research and consulting facets of this work, and the collaborations he has participated in over his career which has tracked with technical and geopolitical developments. Deckman emphasizes ExxonMobil’s commitment to research in non-petroleum energy sources in parallel with finding new oil and gas reserves. He discusses: his childhood outside of Cleveland; early interests in science and the excellent public school offerings he received; undergraduate education at Case Western where he focused on solid state physics; his decision to go to Iowa State for his PhD, where Constantine Stassis supervised his thesis research on magnetic neutron scattering; his initial appointment in Exxon’s Corporate Research Lab to work on laser fusion, the impetus of this research in light of the energy crisis of the 1970s, and the many experiments and collaborations in the Lab that mixed basic and applied science, including the demonstration that laser plasma could be a source for X-ray lithography; the rise of soft matter physics as a discrete subfield, and the impact of the information revolution in the 1980s on his research agenda and his focused interest in absorbed molecules and studying isotherms and transport; his work with novel reactors and coupled waves in geoscience, and why his work in carbon dioxide separations marked a major turning point in his career both as a fascinating area of research and because of the imperative at Exxon to address carbon emissions; his work on hydrocarbons and their value as an affordable energy source; his interests, in retirement, to continue searching for solutions for greenhouse gas mitigation strategies.
