Einstein's Derivation of the Famous Equation, E=mc2
Quite surprisingly, you just need ordinary algebra, no calculus, no tensors to scare the hell out of you.

Enjoy.

You lost me on the first diagram.

This is why I work towards biology and modern history at school.

There are less numbers and such in those...

The diagram just shows a particle decays, giving off two gamma rays moving in opposite direction.

This video gives a bit of a feel for the derivation, even if you aren't that interested in the maths itself:



Give me your argument in the form of a published paper, and then we can start to talk.

I recommend "Why does E=mc2" by Brian Cox and some other dude. Much easier to follow. Explains things instead of just throwing algebra and trig in your face in your face.

Edit: Good explanation in that video.

Thanks. I loved the cat analogy.

Remarkably Einstein derived his equation without any math wizardry. When I first learned it, that was through tensors calculus, now called differential geometry. And the derivation was much shorter, but that's only because we had spent three to four weeks developping the math formalism. Einstein did it with simple math but with a lot of physical insight.
