While most [[science]] historians{{fact}} would claim that [[Isaac Newton]] was arguably the greatest scientist in [[history]], Albert Einstein is surely the most widely recognized scientist in the modern world--no captions are needed on his photographs, and practically every adult in the world immediately recognizes him.

He received the [[Nobel Prize]] in 1921 "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect".

Einstein's meteoric rise to world fame came after the publication of Sir [[Arthur Eddington]]'s observations on the bending of [[star]]light passing nearby the [[Sun]], which were taken during the total [[solar eclipse]] of May 29, 1919, and which were proclaimed to be the first [[observation]]al [[proof]]s of Einstein's theory of [[General Relativity]].

Einstein's 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 state-state nature of the universe.

[[Edwin Hubble]], of whom [[NASA]]'s famous [[Hubble Space Telescope]] is named in honor, later convinced him otherwise.  At one point he had Einstein actually making direct [[observation]]s alongside him, and Hubble's [[finding]]s showed conclusively that the [[universe]] was indeed [[expand]]ing, as predicted by certain solutions of GR's field equations in the absence of a cosmological constant.  Einstein recanted his original [[philosophy]], and accepted as true the notion of a changing [[universe]] having a definite [[begin]]ning.

He later said of the Cosmological Constant, <nowiki>"It was the biggest blunder of my life."</nowiki> A cosmological constant of the opposite sign is now commonly accepted among cosmologists as a way of explaining the accelerating expansion of the universe.
