Best known for developing the theory of relativity, Einstein also made important contributions to quantum mechanics.[1][5] His mass–energy equivalence formula E = mc2, which arises from relativity theory, has been called "the world's most famous equation".[6] He 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",[7] a pivotal step in the development of quantum theory. His intellectual achievements and originality have made the word Einstein broadly synonymous with genius
