Derivation of E=mc^2

samedi 3 mai 2014

Reading into some special relativity, I have seen E=mc^2 proposed from the assumption of four momentum conservation and the fact that the 'mass' component varies with velocity with the gamma factor, like a kinetic energy.



This seems a bit of a leap of faith to me so I was wondering if there are more rigorous derivations preferably only assuming special relativity?
