Interview with Steven Kivelson, Prabhu Goel Family Professor of Physics at Stanford University. Kivelson recounts his childhood in Los Angeles as the son of academic scientists, and he describes his transition from career ambitions in the law toward physics. He discusses his undergraduate experience at Harvard, and he describes his lack of appreciation of the stature of many of the physics professors, such as his advisor Paul Martin, whom he knew first as a friend of his parents.

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.
