Albert Einstein (March 14, 1879 in Ulm, Württemberg, Germany – April 18, 1955 in Princeton, New Jersey) was a theoretical physicist. He was the formulator of the special and general theories of relativity. In addition, he made significant contributions to quantum theory and statistical mechanics. While best known for the Theory of Relativity (and specifically mass-energy equivalence, E=mc2), he was awarded the 1921 Nobel Prize for Physics for his explanation of the photoelectric effect in 1905 (his \"wonderful year\" or \"miraculous year\") and \"for his services to Theoretical Physics\". For his many contributions, Einstein is widely regarded as one of the greatest physicists who ever lived.In popular culture, the name \"Einstein\" has become synonymous with great intelligence and genius.
