question: Which Welsh theoretical physicist and professor emeritus of physics at the University of Cambridge is the discovery of the supercurrent in SNS contacts is sometimes mistakenly attributed to
answer: Brian David Josephson
context: Title: Grelling–Nelson paradox
  Passage: The Grelling–Nelson paradox is a semantic self-referential paradox concerning the applicability to itself of the word "heterological", meaning "inapplicable to itself."  It was formulated in 1908 by Kurt Grelling and Leonard Nelson and sometimes mistakenly attributed to the German philosopher and mathematician Hermann Weyl.
  Title: Nozomi Witches
  Passage: Nozomi Witches (のぞみ♡ウィッチィズ , Nozomi Uicchizu ) , sometimes also called Bewitching Nozomi, is a manga series by Toshio Nobe which was adapted into a three episode anime OVA series in 1992.  Because of similarities with Mitsuru Adachi's style, and the fact that the OVA adaptation was made by the team that worked on several of his anime adaptations, "Nozomi Witches" is sometimes mistakenly attributed as one of Adachi's works.
  Title: Brian Josephson
  Passage: Brian David Josephson, {'1': ", '2': ", '3': ", '4': "} (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 Josephson effect, made in 1962 when he was a 22-year-old PhD student at Cambridge University.  Josephson is the only Welshman 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.
  Title: Proximity effect (superconductivity)
  Passage: Proximity effect or Holm-Meissner effect is a term used in the field of superconductivity to describe phenomena that occur when a superconductor (S) is placed in contact with a "normal" (N) non-superconductor.  Typically the critical temperature formula_1 of the superconductor is suppressed and signs of weak superconductivity are observed in the normal material over mesoscopic distances.  The proximity effect is known since the pioneering work by R. Holm and W. Meissner.  They have observed zero resistance in SNS pressed contacts, in which two superconducting metals are separated by a thin film of a non-superconducting (i.e. normal) metal.  The discovery of the supercurrent in SNS contacts is sometimes mistakenly attributed to Brian Josephson's 1962 work, yet the effect was known long before his publication and was understood as the proximity effect.
  Title: Gerald E. Brown
  Passage: Gerald Edward "Gerry" Brown (born July 22, 1926 in Brookings, South Dakota; † May 31, 2013 in New York City) was an American theoretical physicist who worked on nuclear physics and astrophysics.  Since 1968 he had been a professor at the Stony Brook University.  He was a distinguished professor emeritus of the C. N. Yang Institute for Theoretical Physics at Stony Brook University.
  Title: Andrzej Buras
  Passage: Andrzej Jerzy Buras (born 26 October 1946 in Warsaw, Poland) is a theoretical physicist, professor emeritus at the Technical University Munich (TUM).  He received his master's degree in theoretical physics at the Warsaw University in 1971, and emigrated to Denmark in the same year.  One year later, he received his PhD at the Niels Bohr Institute in Copenhagen.  He then worked as a post-doctoral fellow at the Niels Bohr Institute until 1975.  After a fellowship in the CERN theory group from 1975-1977 he was first a visitor and then a staff member in the Fermilab theory group from 1977 till 1982.  He then became staff member of the Max Planck Institute for Physics in Munich (1982-1988).  In 1988 finally he was appointed full professor in the Physics Department of the TUM.  After his retirement in 2012 he moved to the TUM Institute for Advanced Study where he is leading the focus group 'Fundamental Physics'.
  Title: Fayyazuddin
  Passage: Fayyazuddin or Fayyaz Uddin, HI (Urdu: فيا ض ا لدين) (born 10 November 1930), is a Pakistani theoretical physicist and an Emeritus Professor of Theoretical and Mathematical Physics at National Centre for Physics and Quaid-e-Azam University, Islamabad.  He is a senior scientist at the National Center for Physics where his research is engaged to the fields of quantum mechanics, particle physics, and meson physics.  He is a brother of physicist Riazuddin and the student of Abdus Salam.  Along with Riazuddin, he has published numerous physics papers and has co-authored the "Quantum Mechanics by Fayyazuddin and Riazuddin" which was published in 2000.
  Title: John David Jackson (physicist)
  Passage: John David Jackson (January 19, 1925 – May 20, 2016) was a Canadian–American physics professor emeritus at the University of California, Berkeley and a faculty senior scientist emeritus at Lawrence Berkeley National Laboratory.  A theoretical physicist, he was a member of the National Academy of Sciences, and is well known for numerous publications and summer-school lectures in nuclear and particle physics, as well as his widely-used graduate text on classical electrodynamics.
  Title: François Englert
  Passage: François Baron Englert (] ; born 6 November 1932) is a Belgian theoretical physicist and 2013 Nobel prize laureate (shared with Peter Higgs).  He is Professor emeritus at the Université libre de Bruxelles (ULB) where he is member of the Service de Physique Théorique.  He is also a Sackler Professor by Special Appointment in the School of Physics and Astronomy at Tel Aviv University and a member of the Institute for Quantum Studies at Chapman University in California.  He was awarded the 2010 J. J. Sakurai Prize for Theoretical Particle Physics (with Gerry Guralnik, C. R. Hagen, Tom Kibble, Peter Higgs, and Robert Brout), the Wolf Prize in Physics in 2004 (with Brout and Higgs) and the High Energy and Particle Prize of the European Physical Society (with Brout and Higgs) in 1997 for the mechanism which unifies short and long range interactions by generating massive gauge vector bosons.  He has made contributions in statistical physics, quantum field theory, cosmology, string theory and supergravity.  He is the recipient of the 2013 Prince of Asturias Award in technical and scientific research, together with Peter Higgs and the CERN.
