Talk:Counterexamples to Relativity (view source)
Revision as of 19:52, December 6, 2011
, 19:52, December 6, 2011→Deleted example to releativity: energy can be calculated in other ways also
::::: Nuclear energy has very little to do with either Einstein or E=mc2. It is based on nuclear forces, and not on anything approaching the speed of light. The development of atomic would have proceeded just the same whether relativity had been discovered or not. Relativity is useful for other things, such as GPS.

:::::: True, it has little to do with E=mc2, but it has something to do with it. I think it's reasonable to suggest that nuclear fusion would have been discovered in the absence of relativity, and that therefore the famous equation might have been discovered empirically by observing mass/energy conversions in nuclear processes. However, relativity *did* come first, and the equation is used to calculate energy output for a given mass loss. But you're right, there's lots of other much better examples.--[[User:QPR|QPR]] 13:38, 6 December 2011 (EST)

::::::: The equation E=mc2 can be used, as you say, but the energy can be calculated in other ways also. And there were other reasons for equating mass with energy. Eg, see this 1904 paper. [http://arxiv.org/abs/1108.2250] The key ideas for the atomic bomb were that neutrons stimulate fission and release of energy and more neutrons in uranium, and the neutrons can be manipulated to make a chain reaction.

This page is quite long, and perhaps it should be archived. The downside of archiving is that it can lead to discussions being repeated by those new to the page criticising counterexamples using points which have already been made. To avoid this, I'm willing to summarise the points made, including all points in a non-biased way, as a way to ensure arguments are not repeated. Comments on this suggestion would be greatly appreciated. - [[User:JamesCA|JamesCA]] 01:26, 5 December 2011 (EST)
