Steven Gubser
Steven Scott Gubser (May 4, 1972 – August 3, 2019) was a professor of physics at Princeton University. His research focused on theoretical particle physics, especially string theory, and the AdS/CFT correspondence. He was a widely cited scholar in these and other related areas. Gubser did foundational work in the AdS/CFT correspondence as a graduate student. In particular, his 1998 paper ''Gauge Theory Correlators from Non-Critical String Theory'' with his advisor Igor Klebanov and another Princeton physics professor Alexander Markovich Polyakov, made a precise statement of the AdS/CFT duality. It is one of the all-time top cited papers in theoretical high-energy physics, and is commonly known, along with Edward Witten's 1998 work ''Anti De Sitter Space And Holography'', as the GKPW dictionary. After receiving a Ph.D. in 1998 from Princeton, Gubser became a Junior Fellow at Harvard University before taking a position as an assistant professor at Princeton. In 2001, he moved ...

Valedictorian
Valedictorian is an academic title for the highest-performing student of a graduating class of an academic institution. The valedictorian is commonly determined by a numerical formula, generally an academic institution's grade point average (GPA) system, but other methods of selection may be used or factored in such as community service or extra-curricular activity. The term is an Anglicised derivation of the Latin ''vale dicere'' ("to say farewell"), historically rooted in the valedictorian's traditional role as the final speaker at the graduation ceremony commencement before the students receive their diplomas. The valedictory address, also known as the valediction, is generally considered a final farewell to classmates, before they disperse to pursue their individual paths after graduating. The term is not widely used or known outside the US, although some countries may award equivalent titles. In Australia, the title is sometimes awarded to a member of a graduating universit ...

International Physics Olympiad
The International Physics Olympiad (IPhO) is an annual physics competition for high school students. It is one of the International Science Olympiads. The first IPhO was held in Warsaw, Poland in 1967. Each national delegation is made up of at most five student competitors plus two leaders, selected on a national level. Observers may also accompany a national team. The students compete as individuals, and must sit for intensive theoretical and laboratory examinations. For their efforts the students can be awarded gold, silver, or bronze medals or an honourable mention. The theoretical examination lasts 5 hours and consists of three questions. Usually these questions involve more than one part. The practical examination may consist of one laboratory examination of five hours, or two, which together take up the full five hours. History The idea of creating the International Physics Olympiad was conceived in Eastern Bloc countries, inspired by the 1959 established Internati ...

P-adic Number
In mathematics, the -adic number system for any prime number extends the ordinary arithmetic of the rational numbers in a different way from the extension of the rational number system to the real and complex number systems. The extension is achieved by an alternative interpretation of the concept of "closeness" or absolute value. In particular, two -adic numbers are considered to be close when their difference is divisible by a high power of : the higher the power, the closer they are. This property enables -adic numbers to encode congruence information in a way that turns out to have powerful applications in number theory – including, for example, in the famous proof of Fermat's Last Theorem by Andrew Wiles. These numbers were first described by Kurt Hensel in 1897, though, with hindsight, some of Ernst Kummer's earlier work can be interpreted as implicitly using -adic numbers.Translator's introductionpage 35 "Indeed, with hindsight it becomes apparent that a d ...

Condensed Matter Physics
Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter, especially the solid and liquid phases which arise from electromagnetic forces between atoms. More generally, the subject deals with "condensed" phases of matter: systems of many constituents with strong interactions between them. More exotic condensed phases include the superconducting phase exhibited by certain materials at low temperature, the ferromagnetic and antiferromagnetic phases of spins on crystal lattices of atoms, and the Bose–Einstein condensate found in ultracold atomic systems. Condensed matter physicists seek to understand the behavior of these phases by experiments to measure various material properties, and by applying the physical laws of quantum mechanics, electromagnetism, statistical mechanics, and other theories to develop mathematical models. The diversity of systems and phenomena available for study makes condensed matter phy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quantum Chromodynamics
In theoretical physics, quantum chromodynamics (QCD) is the theory of the strong interaction between quarks mediated by gluons. Quarks are fundamental particles that make up composite hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory, with symmetry group SU(3). The QCD analog of electric charge is a property called ''color''. Gluons are the force carriers of the theory, just as photons are for the electromagnetic force in quantum electrodynamics. The theory is an important part of the Standard Model of particle physics. A large body of experimental evidence for QCD has been gathered over the years. QCD exhibits three salient properties: * Color confinement. Due to the force between two color charges remaining constant as they are separated, the energy grows until a quark–antiquark pair is spontaneously produced, turning the initial hadron into a pair of hadrons instead of isolating a color charge.
