Albert Einstein (/ˈælbərt ˈaɪnstaɪn/; German: [ˈalbɐrt ˈaɪnʃtaɪn] ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist and philosopher of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). He is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the photoelectric effect, a pivotal step in the evolution of quantum theory.
