Josephson has spent his academic career as a member of the Theory of Condensed Matter group at Cambridge'sCavendish Laboratory. He has been a Fellow ofTrinity College, Cambridge, since 1962, and served as Professor of Physics from 1974 until 2007.[4]
In the early 1970s, Josephson took upTranscendental Meditation and turned his attention to issues outside the boundaries of mainstream science. He set up the Mind–Matter Unification Project at Cavendish to explore the idea of intelligence in nature, the relationship betweenquantum mechanics andconsciousness, and the synthesis of science and Eastern mysticism, broadly known asquantum mysticism.[6] He has expressed support for topics such asparapsychology,water memory andcold fusion, which has made him a focus of criticism from fellow scientists.[4][5]
Brian David Josephson was born on 4 January 1940 inCardiff, Wales, toJewish parents, Abraham Josephson and Mimi Weisbard.[2] He attendedCardiff High School,[1] where he credits some of the school masters for having helped him, particularly the physics master, Emrys Jones, who introduced him to theoretical physics.[7] In 1957, he went up to Cambridge, where he initially read mathematics atTrinity College, Cambridge. After completingMaths Part II in two years, and finding it somewhat sterile, he decided to switch to physics.[8]
Josephson was known at Cambridge as a brilliant but shy student. Physicist John Waldram recalled overhearingNicholas Kurti, an examiner from Oxford, discuss Josephson's exam results withDavid Shoenberg, Reader in Physics at Cambridge, and asking: "Who is this chap Josephson? He seems to be going through the theory like a knife through butter."[9] While still an undergraduate, he published a paper on theMössbauer effect, pointing out a crucial issue other researchers had overlooked. According to one eminent physicist speaking toPhysics World, he wrote several papers important enough to assure him a place in the history of physics even without his discovery of theJosephson effect.[10]
Josephson graduated in 1960 and became a research student in the university'sMond Laboratory on the old Cavendish site, where he was supervised byBrian Pippard.[11] American physicistPhilip Anderson, also a future Nobel Prize laureate, spent a year in Cambridge in 1961–1962, and recalled that having Josephson in a class was "a disconcerting experience for a lecturer, I can assure you, because everything had to be right or he would come up and explain it to me after class."[12] It was during this period, as aPh.D. student in 1962, that he carried out the research that led to his discovery of the Josephson effect; theCavendish Laboratory unveiled a plaque on the Mond Building dedicated to the discovery in November 2012.[13] He was elected a Fellow of Trinity College in 1962, and received his Ph.D. in 1964 for a thesis titledNon-linear conduction in superconductors.[14][15]
Josephson spent a postdoctoral year in the United States (1965–1966) as research assistant professor at theUniversity of Illinois at Urbana–Champaign. After returning to Cambridge, he was made Assistant Director of Research at theCavendish Laboratory in 1967, where he remained a member of the Theory of Condensed Matter group, a theoretical physics group, for the rest of his career.[16] He was elected aFellow of the Royal Society (FRS) in 1970,[17] and was awarded aNational Science Foundation fellowship byCornell University the same year. In 1972, he became Reader in Physics at Cambridge, and in 1974 was appointed Professor of Physics, a position he held until his retirement in 2007.[18]

Josephson was 22 years old when he did the work onquantum tunnelling that earned him theNobel Prize in Physics in 1973. He discovered that asupercurrent could tunnel through a thin barrier, predicting, according to physicist Andrew Whitaker, that "at ajunction of two superconductors, a current will flow even if there is no drop in voltage; that when there is avoltage drop, the current should oscillate at a frequency related to the drop in voltage; and that there is a dependence on anymagnetic field."[21] This became known as theJosephson effect and the junction as a Josephson junction.[22]
The Cavendish Laboratory unveiled a plaque on the Mond Building in November 2012 dedicated to the discovery of theJosephson effect.[13]
Josephson's calculations were published inPhysics Letters (chosen by Pippard because it was a new journal) in a paper titled "Possible new effects in superconductive tunnelling," received on 8 June 1962 and published on 1 July.[23][24] They were confirmed experimentally by Philip Anderson and John Rowell ofBell Labs in Princeton; this appeared in their paper, "Probable Observation of the Josephson Superconducting Tunneling Effect," submitted toPhysical Review Letters in January 1963.[25]
Before Anderson and Rowell confirmed the calculations, the American physicistJohn Bardeen, who had shared the 1956 Nobel Prize in Physics (and who shared it again in 1972), objected to Josephson's work. He submitted an article toPhysical Review Letters on 25 July 1962, arguing that "there can be no such superfluid flow." The disagreement led to a confrontation in September that year atQueen Mary College, London, at the EighthInternational Conference on Low Temperature Physics. When Bardeen (then one of the most eminent physicists in the world) began speaking, Josephson (still a student) stood up and interrupted him. The men exchanged views, reportedly in a civil and soft-spoken manner.[26] See also:John Bardeen § Josephson effect controversy.
Whitaker writes that the discovery of the Josephson effect led to "much important physics," including the invention ofSQUIDs (superconducting quantum interference devices), which are used in geology to make highly sensitive measurements, as well as in medicine and computing.[27]IBM used Josephson's work in 1980 to build a prototype of a computer that would be up to 100 times faster than theIBM 3033 mainframe.[28]

Josephson was awarded several important prizes for his discovery, including the 1969Research Corporation Award for outstanding contributions to science,[30] and theHughes Medal andHolweck Prize in 1972. In 1973, he won the Nobel Prize in Physics, sharing the $122,000 award with two other scientists who had also worked on quantum tunnelling. Josephson was awarded half the prize "for his theoretical predictions of the properties of a supercurrent through a tunnel barrier, in particular those phenomena which are generally known as the Josephson effects".[31] The other half of the award was shared equally by Japanese physicistLeo Esaki of the Thomas Watson Research Center in Yorktown, New York, and Norwegian-American physicistIvar Giaever of General Electric in Schenectady, New York.[32]
Josephson became a fellow of Trinity College, Cambridge in 1962.
Josephson became interested inphilosophy of mind in the late 1960s and, in particular, in themind–body problem, and is one of the few scientists to argue that parapsychological phenomena (telepathy,psychokinesis and other paranormal themes) may be real.[33] In 1971, he began practising Transcendental Meditation (TM).[34]
Winning the Nobel Prize in 1973 gave Josephson the freedom to work in less orthodox areas, and he became increasingly involved – including during science conferences, to the irritation of fellow scientists – in talking about meditation, telepathy and higher states of consciousness.[35] In 1974, he angered scientists during a colloquium of molecular and cellular biologists in Versailles by inviting them to read theBhagavad Gita (5th – 2nd century BCE) and the work ofMaharishi Mahesh Yogi, the founder of the TM movement, and by arguing about special states of consciousness achieved through meditation. "Nothing forces us," one scientist shouted at him, "to listen to your wild speculations." BiophysicistHenri Atlan wrote that the session ended in uproar.[36]
In May that year, Josephson addressed a symposium held to welcome the Maharishi to Cambridge.[37] The following month, at the first Canadian conference on psychokinesis, he was one of 21 scientists who tested claims byMatthew Manning, a Cambridgeshire teenager who said he had psychokinetic abilities; Josephson apparently told a reporter that he believed Manning's powers were a new kind of energy.[38] He later withdrew or corrected the statement.[39]
Josephson said that Trinity College's tradition of interest in the paranormal meant that he did not dismiss these ideas out of hand.[40] Several presidents of theSociety for Psychical Research had been fellows of Trinity, and thePerrott-Warrick Fund, set up in Trinity in 1937 to fund parapsychology research, is still administered by the college.[41] He continued to explore the idea that there is intelligence in nature, particularly after readingFritjof Capra'sThe Tao of Physics (1975),[42] and in 1979 took up a more advanced form of TM, known as theTM-Sidhi program. According toAnderson, the TM movement produced a poster showing Josephson levitating several inches above the floor.[43] Josephson argued that meditation could lead to mystical and scientific insights, and that, as a result of it, he had come to believe in a creator.[44]
Josephson became involved in the mid-1970s with a group of physicists associated with theLawrence Berkeley Laboratory at theUniversity of California, Berkeley, who were investigating paranormal claims. They had organized themselves loosely into theFundamental Fysiks Group, and had effectively become theStanford Research Institute's (SRI) "house theorists," according to historian of scienceDavid Kaiser. Core members in the group were Elizabeth Rauscher, George Weissmann, John Clauser, Jack Sarfatti, Saul-Paul Sirag, Nick Herbert, Fred Alan Wolf, Fritjof Capra, Henry Stapp, Philippe Eberhard and Gary Zukav.[45]
Josephson co-organized a symposium on consciousness at Cambridge in 1978, publishing the proceedings asConsciousness and the Physical World (1980),[48] with neuroscientistV. S. Ramachandran. A conference on "Science and Consciousness" followed a year later in Cordoba, Spain, attended by physicists andJungian psychoanalysts, and addressed by Josephson,Fritjof Capra andDavid Bohm (1917–1992).[49]
By 1996, Josephson had set up the Mind–Matter Unification Project at the Cavendish Laboratory to explore intelligent processes in nature.[50] In 2002, he toldPhysics World: "Future science will consider quantum mechanics as the phenomenology of particular kinds of organised complex system. Quantum entanglement would be one manifestation of such organisation, paranormal phenomena another."[10]
Josephson delivered the Pollock Memorial Lecture in 2006, theHermann Staudinger Lecture in 2009 and the SirNevill Mott Lecture in 2010.[51]

Matthew Reisz wrote inTimes Higher Education in 2010 that Josephson has long been one of physics' "more colourful figures."[52] His support for unorthodox causes has attracted criticism from fellow scientists since the 1970s, including fromPhilip Anderson.[53] Josephson regards the criticism as prejudice, and believes that it has served to deprive him of an academic support network.[54]
Josephson has repeatedly criticised "science by consensus," arguing that the scientific community is too quick to reject certain kinds of ideas. "Anything goes among the physics community – cosmic wormholes, time travel," he argues, "just so long as it keeps its distance from anything mystical or New Age-ish." Referring to this position as "pathological disbelief,"[55] he holds it responsible for the rejection by academic journals of papers on the paranormal.[56] He has compared parapsychology to the theory ofcontinental drift, proposed in 1912 byAlfred Wegener (1880–1930) to explain observations that were otherwise inexplicable, which was resisted and ridiculed until evidence led to its acceptance after Wegener's death.[57]
Science writerMartin Gardner criticised Josephson in 1980 for complaining toThe New York Review of Books, along with three other physicists, about an article byJ. A. Wheeler that ridiculed parapsychology.[58] Several physicists complained in 2001 when, in aRoyal Mail booklet celebrating the Nobel Prize's centenary, Josephson wrote that Britain was at the forefront of research into telepathy.[59] PhysicistDavid Deutsch said the Royal Mail had "let itself be hoodwinked" into supporting nonsense, although another physicist,Robert Matthews, suggested that Deutsch was skating on thin ice given the latter's own work onparallel universes andtime travel.[60][61]
In 2004, Josephson criticised an experiment by theCommittee for Skeptical Inquiry to test claims by Russian schoolgirlNatasha Demkina that she could see inside people's bodies using a special kind of vision. The experiment involved her being asked to match six people to their confirmed medical conditions (plus one with none); to pass the test she had to make five correct matches, but made only four.[62] Josephson argued that this was statistically significant, and that the experiment had set her up to fail. One of the researchers,Richard Wiseman, professor of psychology at theUniversity of Hertfordshire, responded by highlighting that the conditions of the experiment had been agreed to before it started, and the potential significance of her claims warranted a higher than normal bar.[63] Keith Rennolis, professor of applied statistics at theUniversity of Greenwich, supported Josephson's position, asserting that the experiment was "woefully inadequate" to determine any effect.[64]
Josephson's reputation for promoting unorthodox causes was cemented by his support for the ideas ofwater memory andcold fusion, both of which are rejected by mainstream scientists. Water memory is purported to provide a possible explanation forhomeopathy; it is dismissed by a majority of scientists aspseudoscience, although he has expressed support for it since attending a conference at which French immunologistJacques Benveniste first proposed it.[65] Cold fusion is the hypothesis that nuclear reactions can occur at room temperature. WhenMartin Fleischmann, the British chemist who pioneered research into it, died in 2012, Josephson wrote a supportive obituary in theGuardian, and had published inNature a letter complaining that its obituary had failed to give Fleischmann due credit.[66]Antony Valentini of Imperial College London withdrew Josephson's invitation to a 2010 conference on thede Broglie-Bohm theory because of his work on the paranormal, although it was reinstated after complaints.[67]
Josephson's defense of paranormal claims and of cold fusion have led him to being described as an exemplar of a sufferer of the hypotheticalNobel disease.[68][69]
