Josephson has spent his academic career as a member of the Theory of Condensed Matter Group in Cambridge's [[Cavendish Laboratory]]. He has been a Fellow of [[Trinity College, Cambridge]], since 1962, and served as Professor of Physics from 1974 until 2007.<ref name=britannica/>

In the early 1970s, Josephson took up [[Transcendental 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 between [[quantum mechanics]] and [[consciousness]], and the synthesis of science and Eastern mysticism, broadly known as [[quantum mysticism]].<ref>[http://talks.cam.ac.uk/show/index/12217 "Mind–Matter Unification Project (TCM Group, Cavendish Laboratory)"], University of Cambridge.<br />

== Education ==
Brian David Josephson was born on 4 January 1940 in [[Cardiff]], Wales, to [[Jewish]] parents, Abraham Josephson and Mimi Weisbard.<ref name=Who>''International Who's Who, 1983–84'', Europa Publications Limited, 1983, p. [https://books.google.com/books?id=_xJ4R0t9G3oC&q=Brian+Josephson 672].</ref> He attended [[Cardiff High School]],<ref name=whoswho/> where he credits some of the school masters for having helped him, particularly the physics master, Emrys Jones, who introduced him to theoretical physics.<ref>Brian Josephson, [http://sms.cam.ac.uk/media/1277021 "Brian Josephson: The Path to the Discovery"], Cavendish Laboratory bdj50 conference, University of Cambridge, June 2012, from 8:20 mins.</ref> In 1957, he went up to Cambridge, where he initially read mathematics at [[Trinity College, Cambridge]]. After completing [[Cambridge Mathematical Tripos|Maths Part II]] in two years, and finding it somewhat sterile, he decided to switch to physics.<ref name="Waldram2012/01:19mins">John Waldram, [http://sms.cam.ac.uk/media/1276329 "John Waldram: Reminiscences"], Lectures from the Cavendish Laboratory's bdj50 conference, University of Cambridge, 18 July 2012, 01:19 mins.</ref>

Josephson was known at Cambridge as a brilliant but shy student. Physicist John Waldram recalled overhearing [[Nicholas Kurti]], an examiner from Oxford, discuss Josephson's exam results with [[David 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."<ref>[http://sms.cam.ac.uk/media/1276329 Waldram 2012], 2:58 mins; for the shyness, Alexei Kojevnikov, [http://www.aip.org/history/ohilist/23362_3.html "Interview with Dr. Philip Anderson"] {{Webarchive|url=https://web.archive.org/web/20130514031624/http://www.aip.org/history/ohilist/23362_3.html |date=14 May 2013 }}, Session III, Princeton Physics Department Building, 23 November 1999.</ref> While still an undergraduate, he published a paper on the [[Mössbauer effect]], pointing out a crucial issue other researchers had overlooked.

== Career ==
Josephson spent a postdoctoral year in the United States (1965–1966) as Research Assistant Professor at the [[University of Illinois at Urbana–Champaign]]. After returning to Cambridge, he was made Assistant Director of Research in the [[Cavendish Laboratory]] in 1967, where he remained a member of the Theory of Condensed Matter Group for the rest of his career.<ref>[http://www.tcm.phy.cam.ac.uk/ "Cambridge Theory of Condensed Matter group"], University of Cambridge, accessed 14 October 2009.</ref> He was elected a [[List of Fellows of the Royal Society elected in 1970|Fellow of the Royal Society (FRS) in 1970]],<ref name=frs>{{cite web|archive-url=https://web.archive.org/web/20151124101944/https://royalsociety.org/people/brian-josephson-11712/|archive-date=24 November 2015|url=https://royalsociety.org/people/brian-josephson-11712/|title=Professor Brian Josephson FRS|publisher=[[Royal Society]]|location=London}}</ref> and was awarded a [[National Science Foundation]] Fellowship by [[Cornell University]] the same year. In 1972, he became Reader in Physics, and in 1974 was appointed Professor of Physics—a position he held until his retirement in 2007.<ref name="Nobel CV">[http://nobelprize.org/nobel_prizes/physics/laureates/1973/josephson-bio.html "Brian D.

Josephson was 22-years-old when he did the work on [[quantum tunnelling]] that earned him the [[Nobel Prize in Physics]] in 1973. He discovered that a [[supercurrent]] could tunnel through a thin barrier, predicting, according to physicist Andrew Whitaker, that "at a [[Electrical junction|junction]] of two superconductors, a current will flow even if there is no drop in voltage; that when there is a [[voltage drop]], the current should oscillate at a frequency related to the drop in voltage; and that there is a dependence on any [[magnetic field]]."<ref>Andrew Whitaker, ''The New Quantum Age: From Bell's Theorem to Quantum Computation and Teleportation'', Oxford University Press, 2012, p. [https://books.google.com/books?id=BaiRvOSaPkwC&pg=PA273 273].</ref> This became known as the [[Josephson effect]] and the junction as a Josephson junction.<ref>James S.

Josephson's calculations were published in ''[[Physics 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.<ref>{{cite journal|doi=10.1016/0031-9163(62)91369-0|title=Possible new effects in superconductive tunnelling|journal=Physics Letters|volume=1|issue=7|pages=251–253|year=1962|last1=Josephson|first1=B.D.|bibcode=1962PhL.....1..251J}}</ref><ref>Also see Brian Josephson, "The History of the Discovery of Weakly Coupled Superconductors," in John Roche (ed.), ''Physicists Look Back: Studies in the History of Physics'', CRC Press, 1990, p.&nbsp;[https://books.google.com/books?id=5H3Oo0iicrkC&pg=PA375 375].</ref> They were confirmed experimentally by Philip Anderson and John Rowell of [[Bell Labs]] in Princeton; this appeared in their paper, "Probable Observation of the Josephson Superconducting Tunneling Effect," submitted to ''[[Physical Review Letters]]'' in January 1963.<ref>Philip Anderson and John Rowell, [http://prl.aps.org/abstract/PRL/v10/i6/p230_1 "Probable Observation of the Josephson Superconducting Tunneling Effect"], ''Physical Review Letters'', 10(6), 15 March 1963 (received 11 January 1963), pp. 230–232.</ref>

Before Anderson and Rowell confirmed the calculations, the American physicist [[John 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 to ''Physical 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 at [[Queen Mary, University of London|Queen Mary College, London]], at the Eighth [[The International Conference on Low Temperature Physics|International 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.<ref>Donald G.

Josephson was awarded several important prizes for his discovery, including the 1969 [[Research Corporation]] Award for outstanding contributions to science,<ref name=Sullivan17Dec1969>Brian Sullivan, [https://news.google.com/newspapers?nid=1913&dat=19691217&id=WH0gAAAAIBAJ&sjid=-mcFAAAAIBAJ&pg=2623,5911644 "Physics is Often a Young Man's Game"], Associated Press, 17 December 1969.</ref> and the [[Hughes Medal]] and [[Holweck 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.

== Parapsychology ==
=== Early interest and Transcendental Meditation ===
Josephson became interested in [[philosophy of mind]] in the late 1960s and, in particular, in the [[mind–body problem]], and is one of the few scientists to argue that parapsychological phenomena ([[telepathy]], [[psychokinesis]] and other paranormal themes) may be real.<ref>Alison George, [https://www.newscientist.com/article/mg19225812.200-lone-voices-special-take-nobodys-word-for-it.html "Lone voices special: Take nobody's word for it"], ''New Scientist'', 9 December 2006 (pp. 56–57), p. 56.</ref> In 1971, he began practising Transcendental Meditation (TM).<ref>Bob Oates, ''Celebrating the Dawn: Maharishi Mahesh Yogi and the TM technique'', Putnam, 1976, p. 204; Emily J. McMurray, Jane Kelly Kosek, and Roger M. Valade, ''Notable Twentieth-Century Scientists'', Gale Research, 1995, p. 1044.<br />
For celebrities and TM, Lola Williamson, ''Transcendent in America'', NYU Press, 2010, p. 93.</ref>

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.<ref>Eliot Marshall, [https://www.jstor.org/stable/3084815 "For Winners, a New Life of Opportunity – and Perils"], ''Science'', 294(5541), 12 October 2001 (pp. 293, 295), p. 295.</ref> In 1974, he angered scientists during a colloquium of molecular and cellular biologists in Versailles by inviting them to read the ''[[Bhagavad Gita]]'' (5th – 2nd century BCE) and the work of [[Maharishi 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." Biophysicist [[Henri Atlan]] wrote that the session ended in uproar.<ref>Henri Atlan, ''Enlightenment to Enlightenment: Intercritique of Science and Myth'', SUNY Press, 1993, pp. [https://books.google.com/books?id=8p1cAi_aj5EC&pg=PA20 20–21].</ref>

In May that year, Josephson addressed a symposium held to welcome the Maharishi to Cambridge.<ref>"Josephson on transcendental meditation," ''New Scientist'', 16 May 1974, p. [https://books.google.com/books?id=5nE6m-bQOvcC&pg=PA416 416]; Stuart Halperin, "The birth of Creative Intelligence," ''New Scientist'', 23 May 1974, p. [https://books.google.com/books?id=e9x3yQmr2fwC&pg=PA459 459].</ref> The following month, at the first Canadian conference on psychokinesis, he was one of 21 scientists who tested claims by [[Matthew 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.<ref>David F.

Josephson became involved in the mid-1970s with a group of physicists associated with the [[Lawrence Berkeley Laboratory]] at the [[University of California, Berkeley]], who were investigating paranormal claims. They had organized themselves loosely into the [[Fundamental Fysiks Group]], and had effectively become the [[SRI International|Stanford Research Institute's]] (SRI) "house theorists," according to historian of science [[David Kaiser (physicist)|David 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.<ref>David Kaiser, [http://shass.mit.edu/multimedia/video-2011-kaiser-how-hippies-saved-physics "How the Hippies Saved Physics"], MIT School of Humanities, Arts and Social Sciences, 2010, from 20:00 mins; for house theorists, from 23:20 mins.</ref>

There was significant government interest at the time in [[quantum mechanics]] – the American government [[Stargate Project (U.S. Army unit)|was financing research]] at SRI into telepathy – and physicists able to understand it found themselves in demand. The Fundamental Fysiks Group used ideas from quantum physics, particularly [[Bell's theorem]] and [[quantum entanglement]], to explore issues such as [[action at a distance]], [[clairvoyance]], [[precognition]], [[remote viewing]] and [[psychokinesis]].<ref>[http://shass.mit.edu/multimedia/video-2011-kaiser-how-hippies-saved-physics Kaiser 2010], from 20:00 mins.</ref>

In 1976, Josephson travelled to California at the invitation of one of the Fundamental Fysiks Group members, [[Jack Sarfatti]], who introduced him to others including laser physicists [[Russell Targ]] and [[Harold E. Puthoff|Harold Puthoff]], and quantum physicist [[Henry Stapp]]. The ''[[San Francisco Chronicle]]'' covered Josephson's visit.<ref>David Kaiser, ''How the Hippies Saved Physics: Science, Counterculture, and the Quantum Revival'', W. W.

Park]], ''Superstition: Belief in the Age of Science'', Princeton University Press, 2009, p. 156.</ref> Josephson regards the criticism as prejudice, and believes that it has served to deprive him of an academic support network.<ref>[https://www.newscientist.com/article/mg19225812.200-lone-voices-special-take-nobodys-word-for-it.html Alison George (''New Scientist'') 2006], p. 57.</ref>

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,"<ref>{{cite journal|last1=Josephson|first1=Brian|title=Pathological Disbelief: Lecture at 54th.

Science writer [[Martin Gardner]] criticised Josephson in 1980 for complaining to ''[[The New York Review of Books]]'', along with three other physicists, about an article by [[John Archibald Wheeler|J. A. Wheeler]] that ridiculed parapsychology.<ref>Olivier Costa de Beauregard, Richard D. Mattuck, Brian D. Josephson and Evan Harris Walker, [http://www.nybooks.com/articles/archives/1980/jun/26/parapsychology-an-exchange/ "Parapsychology: An Exchange"], ''New York Review of Books'', 27, 26 June 1980, pp. 48–51. The other three physicists were [[Evan Harris Walker]] (1935–2006), [[Olivier Costa de Beauregard]] (1911–2007) and Richard D. Mattuck.</ref> Several physicists complained in 2001 when, in a [[Royal Mail]] booklet celebrating the Nobel Prize's centenary, Josephson wrote that Britain was at the forefront of research into telepathy.<ref>Brian Josephson, [http://www.tcm.phy.cam.ac.uk/~bdj10/stamps/text.html "Physics and the Nobel Prizes"], Royal Mail, 2001: "Physicists attempt to reduce the complexity of nature to a single unifying theory, of which the most successful and universal, the quantum theory, has been associated with several Nobel prizes, for example those to Dirac and Heisenberg. Max Planck's original attempts a hundred years ago to explain the precise amount of energy radiated by hot bodies began a process of capturing in mathematical form a mysterious, elusive world containing 'spooky interactions at a distance', real enough however to lead to inventions such as the laser and transistor.<br />"Quantum theory is now being fruitfully combined with theories of information and computation. These developments may lead to an explanation of processes still not understood within conventional science such as telepathy, an area where Britain is at the forefront of research.</ref> Physicist [[David Deutsch]] said the Royal Mail had "let itself be hoodwinked" into supporting nonsense, although another physicist, [[Robert Matthews (scientist)|Robert Matthews]], suggested that Deutsch was skating on thin ice given the latter's own work on [[Many-worlds interpretation|parallel universe]]s and [[Quantum mechanics of time travel|time travel]].<ref>{{cite news|last=McKie|first=Robin|url=https://www.theguardian.com/uk/2001/sep/30/robinmckie.theobserver|title=Royal Mail's Nobel guru in telepathy row|work=The Observer|date=30 September 2001|access-date=13 October 2020}}</ref><ref>{{cite news|last=Matthews|first=Robert|url=https://www.telegraph.co.uk/news/science/science-news/4767204/Time-travel.html|title=Time Travel|work=The Daily Telegraph|date=8 November 2001|access-date=13 October 2020}}<!-- Thursday --></ref>

In 2004, Josephson criticised an experiment by the [[Committee for Skeptical Inquiry]] to test claims by Russian schoolgirl [[Natasha 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.<ref>[https://www.youtube.com/watch?v=36GQou1gBGM "Body Shock: The Girl With X-Ray Eyes"], Discovery Channel, 2004 (for a display from Demkina's perspective, see [https://www.youtube.com/watch?v=g0-si-E6rV0 part 2], from 04:00 mins; for the second, more controlled, experiment, [https://www.youtube.com/watch?v=g0-si-E6rV0 part 2], from 10:30 mins and [https://www.youtube.com/watch?v=dYVCnN0JcsY part 3]).<br />

Skolnick]], [http://www.livescience.com/109-natasha-demkina-girl-normal-eyes.html "Natasha Demkina: The Girl with Very Normal Eyes"], ''LiveScience'', 28 January 2005.</ref> 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 the [[University 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.<ref>Phil Baty, [http://www.timeshighereducation.co.uk/news/scientists-fail-to-see-eye-to-eye-over-girls-x-ray-vision/192922.article "Scientists fail to see eye to eye over girl's 'X-ray vision'"], ''Times Higher Education'', 10 December 2004.<br />

Josephson's reputation for promoting unorthodox causes was cemented by his support for the ideas of [[water memory]] and [[cold fusion]], both of which are rejected by mainstream scientists. Water memory is purported to provide a possible explanation for [[homeopathy]]; it is dismissed by a majority of scientists as [[pseudoscience]], although he has expressed support for it since attending a conference at which French immunologist [[Jacques Benveniste]] first proposed it.<ref>[https://www.newscientist.com/article/mg19225812.200-lone-voices-special-take-nobodys-word-for-it.html George (''New Scientist'') 2006], p. 56.<br />
