I want to do the right thing, but often I don’t know just what the right thing is. Every day I know I have come short of what I would like to have done. Yet as the years pass and I see the very world itself, with its oceans and mountains and plains, as something unfinished, a peculiar little satisfaction hunts out the corners of my heart. Sunsets and evening shadows find me regretful at task’s undone, but sleep and the dawn and the air of the morning touch me with freshening hopes. Strange things blow in through my window on the wings of the night wind and I don’t worry about my destiny.

Albert Einstein

Albert Einstein (German: IPA: [ˈalbɐt ˈaɪ̯nʃtaɪ̯n] (Audio file)   (help·info) ; English: IPA: /ˈælbɝt ˈaɪnstaɪn/) (March 14, 1879 - April 18, 1955) was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass-energy equivalence, E = m c 2 . 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 his special theory of relativity, which reconciled mechanics with electromagnetism, and his general theory of relativity, which extended the principle of relativity to non-uniform motion, creating a new theory of gravitation. His other contributions include relativistic cosmology, capillary action, critical opalescence, classical problems of statistical mechanics and their application to quantum theory, an explanation of the Brownian movement of molecules, atomic transition probabilities, the quantum theory of a monatomic gas, thermal properties of light with low radiation density (which laid the foundation for the photon theory), a theory of radiation including stimulated emission, the conception of a unified field theory, and the geometrization of physics.

Works by Albert Einstein include more than fifty scientific papers and also non-scientific books. In 1999 Einstein was named Time magazine's "Person of the Century", and a poll of prominent physicists named him the greatest physicist of all time. In popular culture the name "Einstein" has become synonymous with genius.
