(1940– )

British physicist, who was awarded the 1973 Nobel Prize for Physics for the discovery of the Josephson effect.

Josephson was educated at Cardiff High School and the University of Cambridge, where he obtained his PhD in 1964. After a year at the University of Illinois, Josephson returned to Cambridge in 1967, becoming professor of physics in 1974.

Josephson's name is associated with the effect he discovered in 1962 while still a graduate student. He predicted that at a superconductor junction, under certain circumstances, a current can cross the junction even when there is no potential difference across it. Shortly afterwards the zero-voltage current predicted by Josephson was detected experimentally. At the same time the oscillating currents produced when a voltage was applied were also found, as predicted by Josephson. Josephson has also lent some support to the study of parapsychology. He has admitted to having been influenced by the Maharishi Mahesh Yogi and in 1980 he called for a new approach to physics in which Krishna consciousness has a place.
