    Albert Einstein

    Albert Einstein(March 14, 1879 – April 18, 1955) was a German-born theoretical physicist. He is widely regarded as one of the greatest physicists who ever lived.He formulated 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".

    Following the May-1919 British solar-eclipse expeditions, whose later analysis confirmed that light rays from distant stars were deflected by the Sun's gravitation as predicted by the Field Equation of general relativity, in November 1919 Albert Einstein became world-famous, an unusual achievement for a scientist. The Times ran the headline on November 7, 1919: "Revolution in science – New theory of the Universe – Newtonian ideas overthrown". Nobel laureate Max Born viewed General Relativity as the "greatest feat of human thinking about nature"; fellow laureate Paul Dirac called it "probably the greatest scientific discovery ever made".In popular culture, the name "Einstein" has become synonymous with great intelligence and genius.

  • Albert Einstein's Early Life

    Einstein was born in Ulm, Germany on Mar. 14, 1879. Einstein's parents, who were non observant Jews, moved from Ulm to Munich when Einstein was an infant. The family business was the manufacture of electrical parts. When the business failed, in 1894, the family moved to Milan, Italy. At this time Einstein decided officially to relinquish his German citizenship. Within a year, still without having completed secondary school, Einstein failed an examination that would have allowed him to pursue a course of study leading to a diploma as an electrical engineer at the Swiss Federal Institute of Technology. He spent the next year in nearby Aarau at the cantonal secondary school, where he enjoyed excellent teachers and first-rate facilities in physics. Einstein returned in 1896 to the Swiss Federal Institute of Technology, where he graduated, in 1900 as a secondary school teacher of mathematics and physics.

    After two years he obtained a post at the Swiss patent office in Bern. The patent-office work required Einstein's careful attention, but while employed (1902-09) there, he completed an astonishing range of publications in theoretical physics. For the most part these texts were written in his spare time and without the benefit of close contact with either the scientific literature or theoretician colleagues. Einstein submitted one of his scientific papers to the University of Zurich to obtain a Ph.D. degree in 1905. In 1908 he sent a second paper to the University of Bern and became a lecturer there. The next year Einstein received a regular appointment as associate professor of physics at the University of Zurich.
