: It is a fact that Poincare published E=mc2 and most of the rest of special relativity before Einstein. Maybe you think that this is sneering or glorifying, but it is a fact, and there is no serious dispute about it. [[User:RSchlafly|RSchlafly]] 20:17, 9 March 2007 (EST)

:: This is true, but what Poincare described was a specific case of E=mc2.  An experimental result showed that there was momentum was a body ejected EM radiation, but without mass.  Poincare described the mass of the EM as m=E/c2.  Einstein derived this formula from more fundamental assumptions, the speed of light is absolute, etc.  This is why his work is so famous.  In fact, in all of science, nothing belongs to any one person, even though they may get credit, but are supposedly discovered.  Also do not forget that Einstein also published General Relativity.

::Furthermore, while Poincare regarded it as superfluous, scientists of the day were still trying to work with the luminescent ether.  Einstein's work proved this unnecessary.

::Again this is a lesson in science.  We are always trying to compress and refine our science.  Einstein, while he of course drew on other's work and surely knew of Poincare's m=E/c2 paper, his work was more refined and simpler, deriving many principles, Poincare's and new ones, from a few fundamental principles.  Poincare published a paper about a month before Einstein with similar work, but in science, no one person makes a discover.  Don't forget, Newton has his Hooke.  But like Newton, it was Einstein's derivation and formalizations that worked better.
