I do not agree with the E=mc2 edits. It suggests that there was something wrong with Poincare's derivation, and that Einstein's is now accepted. But that is not correct. Einstein's derivation was a crude approximation, and had errors. Maybe Planck's view is closer to the modern view, I don't know. But I don't see any justification for the current edit, and I plan to revert it. [[User:RSchlafly|RSchlafly]] 23:54, 13 September 2008 (EDT)

:The point has less to do with the formula itself than what it means, or how to explain it. Poincare didn't even agree with his own attempts to explain it. In fact, what you complain about makes it clear that Poincare's formula was mathematically the same as Einstein's. Maybe you misread it.[[User:Pluto|Pluto]] 13:55, 14 September 2008 (EDT)
