Mathematical physics refers to development of mathematical methods for application to problems in physics. The Journal of Mathematical Physics defines this area as: "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories.".
There are several distinct branches of mathematical physics, and these roughly correspond to particular historical periods. The theory of partial differential equations (and the related areas of variational calculus, Fourier analysis, potential theory, and vector analysis) are perhaps most closely associated with mathematical physics. These were developed intensively from the second half of the eighteenth century (by, for example, D'Alembert, Euler, and Lagrange) until the 1930s. Physical applications of these developments include hydrodynamics, celestial mechanics, elasticity theory, acoustics, thermodynamics, electricity, magnetism, and aerodynamics.
James Clerk Maxwell of GlenlairFRS FRSE (13 June 1831 – 5 November 1879) was a Scottishphysicist and mathematician. His most prominent achievement was formulating classical electromagnetic theory. This unites all previously unrelated observations, experiments, and equations of electricity, magnetism, and optics into a consistent theory.Maxwell's equations demonstrate that electricity, magnetism and light are all manifestations of the same phenomenon, namely the electromagnetic field. Subsequently, all other classic laws or equations of these disciplines became simplified cases of Maxwell's equations. Maxwell's achievements concerning electromagnetism have been called the "second great unification in physics", after the first one realised by Isaac Newton.
Maxwell demonstrated that electric and magnetic fields travel through space in the form of waves and at the constant speed of light. In 1865, Maxwell published A Dynamical Theory of the Electromagnetic Field. It was with this that he first proposed that light was in fact undulations in the same medium that is the cause of electric and magnetic phenomena. His work in producing a unified model of electromagnetism is one of the greatest advances in physics.
Raymond David Flood (born 21 November 1935, in Northam, Southampton, Hampshire) is a former English cricketer. Flood was a right-handed batsman who bowled right-arm off break.
Flood made his first-class debut for Hampshire in the 1956 County Championship against Essex. Flood featured in one other first-class match for Hampshire came in the same season against Northamptonshire.
Flood did not feature for the club in the 1957 County Championship. In the 1958 County Championship Flood featured in one match against Derbyshire.
Flood featured for the club in the 1959 County Championship, where he made more regular appaearances. From the 1959 season to the 1960 County Championship, Flood made 21 first-class appearances for the club. Flood's final first-class match came against Oxford University in 1960, which was Flood's only game for the county that season.
In total Flood represented the club 24 times, scoring 885 runs at an average of 23.28. Flood made five half centuries and one century, which yielded his highest first-class score of 138*, which came against Sussex in 1959.
Edward Witten (born August 26, 1951) is an American theoretical physicist with a focus on mathematical physics who is currently a professor of Mathematical Physics at the Institute for Advanced Study.
Witten is a researcher in superstring theory, a theory of quantum gravity, supersymmetric quantum field theories and other areas of mathematical physics.
He has made contributions in mathematics and helped bridge gaps between fundamental physics and various areas of mathematics. In 1990 he was the world's first physicist to be awarded a Fields Medal by the International Union of Mathematics. In 2004, Time magazine stated that Witten was widely thought to be the world's greatest living theoretical physicist.
Witten was born in Baltimore, Maryland. He is the son of Lorraine W. Witten and Louis Witten, a theoretical physicist specializing in gravitation and general relativity.
Witten attended the Park School of Baltimore (class of '68), and received his Bachelor of Arts with a major in history and minor in linguistics from Brandeis University in 1971. He published articles in The New Republic and The Nation. In 1968 Witten published an article in The Nation arguing that the New Left had no strategy. He worked briefly for George McGovern, a Democratic presidential nominee in 1972. McGovern lost the election in a landslide to Richard Nixon.
