An Interview with Nobel Laureate Douglas Osheroff, Physics 1996



At extremely low temperatures, the molecules of certain fluids are able to flow without internal friction or resistance - a phenomenon know as superfluidity. In this interview, Nobel Laureate Douglas Osheroff (Physics 1996) describes the somewhat arduous quest to prove the predicted superfluid state of helium-3. He also shares his thoughts on mentoring undergraduates and his philosophy on getting the most out of graduate school.

Osheroff, D. An Interview with Nobel Laureate Douglas Osheroff, Physics 1996. J. Vis. Exp. (29), e1540, (2009).


At extremely low temperatures, certain materials conduct electrical currents without resistance – a phenomenon called superconductivity. An analogous state occurs in extremely low-temperature fluids, in which molecules flow without internal friction or resistance. Such a state, termed superfluidity, was predicted for helium-3 shortly after the Bardeen, Cooper, and Schrieffer (BCS) theory of 1957 explained the superconductivity of metals. The search for helium-3 superfluidity commenced; it continued for about ten years without success, and was all but abandoned by the time Douglas D. Osheroff began his graduate studies at Cornell University. "The general wisdom was that the superfluidity of helium-3 was a pipe dream of the theorists," says Osheroff. "But in fact, it did occur." In 1972, Osheroff – together with David M. Lee and Robert C. Richardson – demonstrated the transition of helium-3 to a superfluid state at temperatures near absolute zero (-273°C). Twenty-four years after their discovery, Osheroff and colleagues won the Nobel Prize in Physics. Osheroff’s scientifically inquisitive nature developed long before his landmark discovery. "A lot of people did crazy things when they were young" says Osheroff, whose wild experimentation including building a 100,000-volt X-ray machine as a teenager. Now as a faculty member at Stanford University, Osheroff stresses the importance of mentoring undergraduates to get them excited about science, and to guide them on what to do next. As for graduate school, Osheroff says that "it doesn’t matter what is it that you study as a graduate student – the important thing is learning how to study."
