Brian David Josephson, FRS (born 4 January 1940), is a Welsh theoretical physicist and professor emeritus of physics at the University of Cambridge. Best known for his pioneering work on superconductivity and quantum tunnelling, he was awarded the Nobel Prize in Physics in 1973 for his prediction of the eponymous Josephson effect, made in 1962 when he was a 22-year-old PhD student at Cambridge. Josephson is the only Welsh person to have won a Nobel Prize in Physics. He shared the prize with physicists Leo Esaki and Ivar Giaever, who jointly received half the award for their own work on quantum tunnelling.Josephson has spent his academic career as a member of the Theory of Condensed Matter group at Cambridge's Cavendish Laboratory. He has been a fellow of Trinity College since 1962, and served as professor of physics from 1974 until 2007.In the early 1970s Josephson took up transcendental meditation and turned his attention to issues outside the parameters of mainstream science. He set up the Mind–Matter Unification Project at the Cavendish to explore the idea of intelligence in nature, the relationship between quantum mechanics and consciousness, and the synthesis of science and Eastern mysticism, broadly known as quantum mysticism. Those interests have led him to express support for topics such as parapsychology, water memory and cold fusion, and have made him a focus of criticism from fellow scientists.
