Robert B. Griffiths
Robert B. Griffiths (February 25, 1937) is an American physicist at Carnegie Mellon University. He is the originator of the consistent histories approach to quantum mechanics, which has since been developed by himself, Roland Omnès, Murray Gell-Mann, and James Hartle. Early life and education Robert B. Griffiths was born in Etah, Uttar Pradesh in 1937 to Presbyterian missionaries. Griffiths attended Woodstock School, India from fourth standard to tenth, along with his brothers and sisters. Even during his Woodstock days, Griffiths' mathematical and scientific aptitude was apparent. The 1952 year book remarks that ''"Robert is famous for his long arguments (and unsurpassed knowledge) in chemistry class, his ability to 'recite' the log tables indelibly written in his brain, and his skill when it comes to fixing anything electrical."'' This knack for electrical systems kept Griffiths at Woodstock through part of 1953, working with the school's various wiring systems. Academic caree ...

Etah
Etah is a municipality city which is also the headquarters of Etah District of the Uttar Pradesh state in India.Etah district is a part of the Aligarh Division and is located at the midpoint of the Delhi-Kanpur Highway(NH 91) Known as G.T Road.The nearest Big cities are Aligarh and Agra. History The city lies in the cultural region of Braj and was a part of the Surasena Mahajanapada during the Vedic Age. It was later ruled by the bigger kingdoms like the Mauryas, Guptas, Scythians, Kushans, Indo-Greeks before falling into the hands of local Yadav rulers It is the midpoint on the Kanpur-Delhi Highway. Historically, it is also known for being a center of the Revolt of 1857. In ancient times, Etah was called "Aintha" which means 'to respond aggressively' because of the people of the yadav community, who are very aggressive. It was when the king of Awagarh went hunting in the forest along with his two dogs. The dogs saw a fox and started barking and chasing it. The fox kept ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...

Victor Emery
Victor John Emery (16 May 1934 – 18 July 2002) was a British specialist on superconductors and superfluidity. His model for the electronic structure of the copper-oxide planes is the starting point for many analyses of high-temperature superconductors and is commonly known as the Emery model. Biography Early life Emery was born in Boston, Lincolnshire, England, where he was educated at Staniland School and Boston Grammar School. He won the Parry Gold Medal for the best scholar in 1951 before going on to study physics at the University of Hull, the University of London and the University of Manchester, where he gained a PhD in Theoretical Physics. At school Emery was a keen swimmer and the star goal-scorer of the Boston water polo team. He also won the town's one mile swimming race on the River Witham on more than one occasion Career in Theoretical Physics After completing his studies at Manchester he spent two years as a research associate at Cavendish Laboratory in Cambri ...

Ising Model
The Ising model () (or Lenz-Ising model or Ising-Lenz model), named after the physicists Ernst Ising and Wilhelm Lenz, is a mathematical model of ferromagnetism in statistical mechanics. The model consists of discrete variables that represent magnetic dipole moments of atomic "spins" that can be in one of two states (+1 or −1). The spins are arranged in a graph, usually a lattice (where the local structure repeats periodically in all directions), allowing each spin to interact with its neighbors. Neighboring spins that agree have a lower energy than those that disagree; the system tends to the lowest energy but heat disturbs this tendency, thus creating the possibility of different structural phases. The model allows the identification of phase transitions as a simplified model of reality. The two-dimensional square-lattice Ising model is one of the simplest statistical models to show a phase transition. The Ising model was invented by the physicist , who gave it as a prob ...

Statistical Mechanics
In physics, statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. It does not assume or postulate any natural laws, but explains the macroscopic behavior of nature from the behavior of such ensembles. Statistical mechanics arose out of the development of classical thermodynamics, a field for which it was successful in explaining macroscopic physical properties—such as temperature, pressure, and heat capacity—in terms of microscopic parameters that fluctuate about average values and are characterized by probability distributions. This established the fields of statistical thermodynamics and statistical physics. The founding of the field of statistical mechanics is generally credited to three physicists: *Ludwig Boltzmann, who developed the fundamental interpretation of entropy in terms of a collection of microstates *James Clerk Maxwell, who developed models of probability distr ...

James Hartle
James Burkett Hartle (August 20, 1939) is an American physicist. He has been a professor of physics at the University of California, Santa Barbara since 1966, and he is currently a member of the external faculty of the Santa Fe Institute. Hartle is known for his work in general relativity, astrophysics, and interpretation of quantum mechanics. Work In collaboration with Murray Gell-Mann and others, Hartle developed an alternative to the standard Copenhagen interpretation, more general and appropriate to quantum cosmology, based on consistent histories. With Dieter Brill in 1964, he discovered the Brill–Hartle geon, an approximate solution realizing Wheeler's suggestion of a hypothetical phenomenon in which a gravitational wave packet is confined to a compact region of spacetime by the gravitational attraction of its own field energy. With Kip Thorne, Hartle derived from general relativity the laws of motion and precession of black holes and other relativistic bodies, includi ...
