Yoichiro Nambu (南部 陽一郎 , Nambu Yōichirō , 18 January 1921 – 5 July 2015) was a Japanese-born American physicist, a professor at the University of Chicago.
 Known for his contributions to the field of theoretical physics, he was awarded half of the Nobel Prize in Physics in 2008 for the discovery in 1960 of the mechanism of spontaneous broken symmetry in subatomic physics, related at first to the strong interaction's chiral symmetry and later to the electroweak interaction and Higgs mechanism.
 The other half was split equally between Makoto Kobayashi and Toshihide Maskawa "for the discovery of the origin of the broken symmetry which predicts the existence of at least three families of quarks in nature."
In theoretical physics, the BFSS matrix model or matrix theory is a quantum mechanical model proposed by Tom Banks, Willy Fischler, Stephen Shenker, and Leonard Susskind in 1997.
Hawking proposed that information is lost in black holes, and not preserved in Hawking radiation.
 Susskind disagreed, arguing that Hawking's conclusions violated one of the most basic scientific laws of the universe, the conservation of information.
 As Susskind depicts in his book, "The Black Hole War" was a "genuine scientific controversy" between scientists favoring an emphasis on the principles of relativity against those in favor of quantum mechanics.
 The debate led to the holographic principle, proposed by Gerard 't Hooft and refined by Susskind, which suggested that the information is in fact preserved, stored on the boundary of a system.
The Fischler–Susskind mechanism, first proposed by Willy Fischler and Leonard Susskind in 1998, is a holographic prescription based on the particle horizon.
Abraham S. Fischler (January 21, 1928 – April 3, 2017) was an American academic, and was the second president of Nova Southeastern University.
 Fischler graduated from Columbia University in 1959 with his Ed.D.
 He went on to serve as Assistant Professor of Science Education at Harvard University and Professor of Education at the University of California, Berkeley before joining the fledgling Nova University in 1966.
 Fischler served as Dean of Graduate Studies and Director of the Behavioral Sciences Center from 1966 to 1969.
 He became the President of Nova Southeastern University in 1970 and was President until 1992.
The Susskind–Glogower operator, first proposed by Leonard Susskind and J. Glogower, refers to the operator where the phase is introduced as an approximate polar decomposition of the creation and annihilation operators.
The David Susskind Show is an American television talk show hosted by David Susskind.
 The program began in 1958 as Open End, and was broadcast by WNTA-TV (now WNET) in New York City.
 The title referred to the fact that the program continued until Susskind or his guests were too tired to continue late on a Sunday night.
Leonard Susskind (born 1940) is an American physicist, who is professor of theoretical physics at Stanford University, and director of the Stanford Institute for Theoretical Physics.
 His research interests include string theory, quantum field theory, quantum statistical mechanics and quantum cosmology.
 He is a member of the National Academy of Sciences of the US, and the American Academy of Arts and Sciences, an associate member of the faculty of Canada's Perimeter Institute for Theoretical Physics, and a distinguished professor of the Korea Institute for Advanced Study.
A red team or the red team is an independent group that challenges an organization to improve its effectiveness.
 It is particularly effective in organizations with strong cultures and fixed ways of approaching problems.
 The United States intelligence community (military and civilian) has red teams that explore alternative futures and write articles as if they were foreign world leaders.
 Little formal doctrine or publications about Red Teaming in the military exist, but its basic principles are emulated elsewhere, such as the response-rebuttal letters posted in the California Guide for Voters.
 Recently a physicist proposed a Red Team exercise to elucidate climate change and climate warming science.
The S1 reaction is a substitution reaction in organic chemistry.
 "S" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular.
 Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile.
 This relationship holds for situations where the amount of nucleophile is much greater than that of the carbocation intermediate.
 Instead, the rate equation may be more accurately described using steady-state kinetics.
 The reaction involves a carbocation intermediate and is commonly seen in reactions of secondary or tertiary alkyl halides under strongly basic conditions or, under strongly acidic conditions, with secondary or tertiary alcohols.
 With primary and secondary alkyl halides, the alternative S2 reaction occurs.
 In inorganic chemistry, the S1 reaction is often known as the "dissociative mechanism".
 This dissociation pathway is well-described by the cis effect.
 A reaction mechanism was first proposed by Christopher Ingold et al. in 1940.
 This reaction does not depend much on the strength of the nucleophile unlike the S2 mechanism.this type of mechanism involves two steps the first step is the reversible ionization of Alkyl halide in the presence of aqueous acetone or an aqueous ethyl alcohol this step provides a carbocation as an intermediate in second step this carbocation is attacked by the nucleophile to give the product
