Brian David Josephson, FRS[1] (born 4 January, 1940; Cardiff, Wales[2]) is a Welsh physicist. He became a Nobel Prize laureate in 1973 at the age of 33 with Leo Esaki and Ivar Giaever, and he predicted the eponymous Josephson effect.[2]

As of autumn 2007, he is a retired professor at the University of Cambridge where he is the head of the mind-matter unification project in the Theory of Condensed Matter research group. He is also a fellow of Trinity College, Cambridge.[3]

Education

Brian Josephson attended Cardiff High School and then Cambridge University, where he gained a B.A. in 1960[4] Whilst an undergraduate, he became notorious as a brilliant and self assured student.[2] A former lecturer remembers the importance of being particularly precise if addressing a class that included Josepshon; if a mistake was made, Josephson would not be afraid to politely point it out after the lecture.[2] As an undergraduate he published a paper in which he calculated a thermal correction to the Mössbauer effect that reconciled previously different measurements of gravitational red shifts reported by teams in the US and UK.[5] After completing his undergraduate degree he continued to study at Cambridge, and in 1964 was awarded his Ph.D. in physics[4]

Academic Career

Josephson became a fellow of Trinity College, Cambridge in 1962[4] before moving to the United States of America to take a position as Research Assistant Professor at the University of Illinois.[4] He returned to Cambridge University in 1967 as an Assistant Director of Research at the Cavendish Laboratory and then a professor of physics in 1974,[4] a position he retained until his retirement in 2007.

Since 1983 Josephson has been appointed a Visiting Professor at various institutions including the Wayne State University, Detroit in 1983,[4] the Indian Institute of Science, Bangalore in 1894[4] and the University of Missouri-Rolla in 1987.[4]

Josephson was a member of the Theory of Condensed Matter (TCM) Group, a theoretical physics group at the Cavendish Laboratory, for much of his research career.[6] While working at TCM group he was jointly awarded the Nobel Prize in Physics in 1973 while still only a Reader in Physics. He shared the award with Japanese physicist Leo Esaki and American physicist Ivar Giaever who each received a 1/4 of the prize, with 1/2 going to Josephson.[7] Interestingly, along with Josesphson, neither Esaki nor Giaever held professorships at the time of the award. It is rare that academics ranked below professors win the prestigious prize.[8]

Josephson also directed the Mind-Matter Unification Project in TCM Group[9].

Research

Josephson Effect

Josephson is best known for his pioneering theoretical work on superconductivity, earning him a 1/2 share of the 1973 Nobel Prize for Physics.[5] Specifically, it was awarded 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",[7] which led to the invention of the Josephson junction. These juctions are key components in devices used to make highly sensitive measurements in magnetic fields.[5] Further use for his discoveries was realised by researchers at the International Business Machines Corporation who, by 1980, had assembled an experimental computer switch structure, which would permit switching speeds from 10 to 100 times faster than those possible with conventional silicon-based chips, increasing data processing capabilities by a vast amount.[2] However, controversially he has stated that his "work on the brain is more significant than my[his] Nobel-prize winning research."[10]

Mind-Matter Unification Project

Josephson directed the Mind-Matter Unification Project, which he describes as: "a project concerned primarily with the attempt to understand, from the viewpoint of the theoretical physicist, what may loosely be characterised as intelligent processes in nature, associated with brain function or with some other natural process"[10]. More generally, the research involves how the brain works, investigating topics such as language and consciousness, and pondering the fundamental connections between music and the mind.[5] It is based on the belief that quantum mechanics is not the ultimate theory of nature. [5] He maintains that "Quantum Theory is not a complete picture of nature even though it is correct in its own domain.[11] He believes ideas such as Complementarity in Physics may also apply to Biology,[11] an idea originally proposed by Neils Bohr[12]. However, this idea was opposed by Bohr's contemporary Delbrück who maintained that life's processes were dependent on macroscopic interactions and not quantum effects. citation needed

Despite his retirement Josephson continues to be active within the Mind-Matter Unification project.[10] Among his aims is to find mechanisms behind phenomena such as the possibility that organisms can learn to bias the statistics ofsupposedly random physical processes through having a better understanding of its patterns than non-living matter.[5]

Science and religion

Josephson has participated in science and religion discussions. Regarding conflict, he stated "I don't see a conflict. There are conflicts between the views of many scientists on religion, but I think there need be no ultimate conflict. Science may be capable of extension in a way that is compatible with the tenets of religion."[13]


Paranormal

Josephson is one of the more well-known scientists who say that parapsychological phenomena may be real, and is also interested in the possibility that Eastern mysticism may have relevance to scientific understanding.[10] He has said that one of his guiding principles has been nullius in verba (take nobody's word), saying that "if scientists as a whole denounce an idea, this should not necessarily be taken as proof that the said idea is absurd; rather, one should examine carefully the alleged grounds for such opinions and judge how well these stand up to detailed scrutiny."[10][5]

In 2001 Josephson's views on the paranormal were under the spotlight when he wrote about them in a booklet to accompany six special stamps to honour the 100th anniversary of the Nobel prize.[14] The Royal mail had sent Josephson a request to write a small article about their award and the implication of research in their field they could use in conjunction with the special Nobel Centenary stamp issue.[14] He wrote the following:

"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.

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.">[10]</blockquote

He came under criticism from several fellow physicists including David Deutsch, a quantum physicist at Oxford University who stated "It is utter rubbish. Telepathy simply does not exist. The Royal Mail has let itself be hoodwinked into supporting ideas that are complete nonsense".[14] However, Josephson maintains 'There is a lot of evidence to support the existence of telepathy, for example, but papers on the subject are being rejected - quite unfairly.'[14]
