About Albert Einstein Albert Einstein (pronounced /ˈælbərt ˈaɪnstaɪn/; German: Albert_Einstein_german.ogg ˈalbɐt ˈaɪ̯nʃtaɪ̯n ; 14 March 1879 – 18 April 1955) was an ethnically Jewish, German-born theoretical physicist. He is best known for his theories of special relativity and general relativity. Einstein received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect."Einstein's many contributions to physics include: * The special theory of relativity, which reconciled mechanics with electromagnetism * The general theory of relativity, a new theory of gravitation obeying the equivalence principle. * Founding of relativistic cosmology with a cosmological constant * The first post-Newtonian expansion, explaining the perihelion advance of Mercury * Prediction of the deflection of light by gravity and gravitational lensing * The first fluctuation dissipation theorem which explained the Brownian movement of molecules * The photon theory and wave-particle duality derived from the thermodynamic properties of light * The quantum theory of atomic motion in solids * Zero-point energy * The semiclassical version of the Schrodinger equation * Relations for atomic transition probabilities which predicted stimulated emission * The quantum theory of a monatomic gas which predicted Bose-Einstein condensation * The EPR paradox * A program for a unified field theory * The geometrization of fundamental physics. Einstein published more than 300 scientific works and more than 150 non-scientific works.In 1999 Time magazine named him the Person of the Century, and in the words of a biographer, "to the scientifically literate and the public at large, Einstein is synonymous with genius."
