'''Albert Einstein''' (1879-1955) was a theoretical physicist who contributed to the theory of a [[Special Relativity]] and the theory of [[General Relativity]]. He also contributed to the study of Photoelectric Effect, Brownian Motion and Bose-Einstein Statistics.  He was critical of quantum mechanics and has proposed the EPR-Paradox in attempt to point out spooky aspects of the theory.  The last fifteen years of his life were spent in unsuccessfully searching for a [[Unified Field Theory]].  Born in Germany in a Jewish familiy, he won the [[Nobel Prize]] for his work on the Photoelectric Effect in 1921.<ref>http://nobelprize.org/nobel_prizes/physics/laureates/1921/</ref>  He immigrated to the United States in the late 1930s where, upon the urging of a colleague in physics, recommended that President Franklin D. Roosevelt develop an [[atomic bomb]] project.<ref>[http://www.dannen.com/ae-fdr.html]</ref>He later regretted this and became a passionate pacifist.  In 1952, he was offered the Presidency of Israel, but he turned it down.  

'''Albert Einstein''' (1879-1955) was a theoretical physicist. Born in Ulm, in Württemberg, Germany in a Jewish familiy. During his stay at the Swiss Patent Office he produced much of his remarkable work. In 1905 he obtained his doctor's degree. He won the [[Nobel Prize]] for his work on the Photoelectric Effect in 1921. <ref>http://nobelprize.org/nobel_prizes/physics/laureates/1921/</ref>  He immigrated to the United States in the late 1930s to take the position of Professor of Theoretical Physics at Princeton; upon the urging of a colleague in physics, recommended that President Franklin D. Roosevelt develop an [[atomic bomb]] project. <ref>[http://www.dannen.com/ae-fdr.html]</ref> He later regretted this and became a passionate pacifist.  In 1952, he was offered the Presidency of Israel, but he turned it down. He collaborated with Dr. Chaim Weizmann in establishing the Hebrew University of Jerusalem.  

Einstein's best-known scientific work is his 1905 papers on [[Special Relativity]]. The theory of relativity had already been published by [[Hendrik Lorentz]] and [[Henri Poincaré]]. Einstein's contribution was to give a description of the Lorentz-Poincare theory without reference to the luminiferous aether, and to clarify some of the physical consequences of the theory.

Robert Massey of the Royal Astronomical Society said: 'From the most esoteric aspects of time dilation through to the beautiful and simple equation, E=mc², the vast bulk of Einstein's ideas about the universe are standing up to the test of time,'

==Cosmological Constant==

===Cosmological Constant===

Einstein revised his work on [[General Relativity]] to include a 'fudge-factor' which he termed the [[Cosmological Constant]]. He was trying to account for the apparent steady-state nature of the universe.

An interesting end-note on this term: Principle investigators from [[Princeton University]] first published findings in 1998 apparently revealing an accelerating expansion for the universe<ref>http://map.gsfc.nasa.gov/m_mm.html</ref>. Because this initially seemed like it might be a sort of 'anti-gravity' effect (similar in concept to Einstein's original notion), it briefly became quite popular for scientists to dub the phenomenon the 'Cosmological Constant' as well.  For more information, see: [[Dark Energy]].
