Question: Behram Kurşunoğlu was a Turkish physicist who hosted several Nobel Prize Laueates including an American physicist who pineerd the stufy of electron scatter in what?
Context: Prof Albert Abraham Michelson (surname pronunciation anglicized as "Michael-son") FFRS HFRSE LLD (December 19, 1852 – May 9, 1931) was an American physicist known for his work on measuring the speed of light and especially for the Michelson–Morley experiment.  In 1907 he received the Nobel Prize in Physics, becoming the first American to win the Nobel Prize in a science. Hans Georg Dehmelt (9 September 1922 – 7 March 2017) was a German-born American physicist, who was awarded Nobel Prize in Physics in 1989, for co-developing the ion trap technique (Penning trap) with Wolfgang Paul, for which they shared one-half of the prize (the other half of the Prize in that year was awarded to Norman Foster Ramsey).  Their technique was used for high precision measurement of the electron magnetic moment. Ernst August Friedrich Ruska (25 December 1906 – 27 May 1988) was a German physicist who won the Nobel Prize in Physics in 1986 for his work in electron optics, including the design of the first electron microscope. Aage Niels Bohr (] ; 19 June 1922 – 8 September 2009) was a Danish nuclear physicist who shared the Nobel Prize in Physics in 1975 with Ben Mottelson and James Rainwater "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection".  Starting from Rainwater's concept of an irregular-shaped liquid drop model of the nucleus, Bohr and Mottelson developed a detailed theory that was in close agreement with experiments.  Since his father, Niels Bohr, had won the prize in 1922, he and his father were one of the six pairs of fathers and sons who have both won the Nobel Prize and one of the four pairs who have both won the Nobel Prize in Physics. Willis Eugene Lamb Jr. ( ; July 12, 1913 – May 15, 2008) was an American physicist who won the Nobel Prize in Physics in 1955 "for his discoveries concerning the fine structure of the hydrogen spectrum."  The Nobel Committee that year awarded half the prize to Lamb and the other half to Polykarp Kusch, who won "for his precision determination of the magnetic moment of the electron."  Lamb was able to determine precisely a surprising shift in electron energies in a hydrogen atom (see Lamb shift).  Lamb was a professor at the University of Arizona College of Optical Sciences. Robert Hofstadter (February 5, 1915 – November 17, 1990) was an American physicist.  He was the joint winner of the 1961 Nobel Prize in Physics (together with Rudolf Mössbauer) "for his pioneering studies of electron scattering in atomic nuclei and for his consequent discoveries concerning the structure of nucleons". In condensed matter physics, a Cooper pair or BCS pair is a pair of electrons (or other fermions) bound together at low temperatures in a certain manner first described in 1956 by American physicist Leon Cooper.  Cooper showed that an arbitrarily small attraction between electrons in a metal can cause a paired state of electrons to have a lower energy than the Fermi energy, which implies that the pair is bound.  In conventional superconductors, this attraction is due to the electron–phonon interaction.  The Cooper pair state is responsible for superconductivity, as described in the BCS theory developed by John Bardeen, Leon Cooper, and John Schrieffer for which they shared the 1972 Nobel Prize. Mohammad Abdus Salam {'1': ", '2': ", '3': 'NI, SPk, KBE', '4': "} (Punjabi, Urdu: ‎ ; ] ; 29 January 192621 November 1996), was a Pakistani theoretical physicist.  A major figure in 20th century theoretical physics, he shared the 1979 Nobel Prize in Physics with Sheldon Glashow and Steven Weinberg for his contribution to the electroweak unification theory.  He was the first Pakistani and first Muslim to receive a Nobel Prize in science and the second from an Islamic country to receive any Nobel Prize (after Anwar Sadat of Egypt). Clinton Joseph Davisson (October 22, 1881 – February 1, 1958), was an American physicist who won the 1937 Nobel Prize in Physics for his discovery of electron diffraction in the famous Davisson-Germer experiment.  Davisson shared the Nobel Prize with George Paget Thomson, who independently discovered electron diffraction at about the same time as Davisson. Behram Kurşunoğlu (14 March 1922 – 25 October 2003) was a Turkish physicist and the founder and the director of the Center for Theoretical Studies, University of Miami.  He was best known for his works on unified field theory, energy and global issues.  Moreover, he participated in the discovery of two different types of neutrinos in late 1950s.  During his University of Miami career, he hosted several Nobel Prize laureates, including Paul Dirac, Lars Onsager and Robert Hofstadter.  He wrote several books on diverse aspects of physics, the most notable of which is "Modern Quantum Theory" (1962).
