John Reppy

David John Reppy ( born February 16, 1931 in Lakewood ( New Jersey)) is an American physicist, well known for research on quantum fluids ( superfluid helium) and superconductors.

Life

Reppy studied at the University of Connecticut with a bachelor's degree in 1954 and a master's degree in 1956 and in 1961 received his doctorate from Yale University in physics. 1962 to 1966 he was assistant professor at Yale and Associate Professor in 1966 and later John Wetherill Professor at Cornell University. In 2005 he retired.

He was a visiting scientist at Bell Laboratories, Massachusetts Institute of Technology, the University of Manchester and the University of Sussex.

It deals with superfluids ( in 4He and 3He, and Suprasolidität in solid He 4 ), in recent times especially boundary conditions and phase transitions in reduced dimensionality. He worked with the Nobel Prize, David M. Lee and Robert C. Richardson at Cornell University. Reppy claimed early observations of Bose - Einstein condensates (1983 ) in experiments with helium 4 in small pores ( in the nanometer range ) of a sponge-like glass ( Vycor ).

Reppy is a Fellow of the National Academy of Sciences, the American Physical Society, the Institute of Physics, the New York Academy of Sciences and the American Association for the Advancement of Science. In 1981 he received the Fritz London Memorial Award. 1972 to 1973 and 1979 to 1980 he was Guggenheim Fellow.

2000 was awarded the NASA Distinguished Public Service Award for participation in microgravity experiments. In 2000 he became a Fellow of the Japan Society for the Promotion of Science. In 1978 he was a Fulbright - Hays Fellow.

He's since his youth, a well-known rock climber with ascents of routes in his home area, the Ragged Mountains in Connecticut ( about which he wrote a climbing guide ), at Mount Katahdin in Maine, the Shawangunks in the Tetons in the Rocky Mountains and at Cannon Mountain in New Hampshire. He climbed a lot in England and the Alps and has long been an advocate of clean climbing methods.

He is married to Judith Voris since 1959 and has three children.

He is not to be confused with the professor for computer science John H. Reppy in Chicago.
