There is nothing more frightful than ignorance in action.

E = mc^2 is not the complete story, that is for masses at rest (zero velocity relative to your momentum); the Pythagorean analogue is much better, described in this YouTube video:

Or a more indepth of the same thing from my favorite physics channel

For those who are slightly math inclined see my blog:Einstein's Derivation of the Famous Equation, E=mc2. What's interesting is that his 1905 paper contained no calculus, no fancy math gymnastics to get his result. He does have a formula that he did not derive, but it was well-known at the time. I derived that formula in my next blog, Relativistic Doppler Effect. Though here, a little math is de rigueur. It's not for the faint- hearted. If you are also interested to know how Newton's is contained in Einstein's field equations, see: Is Newtonian Gravitational Fields Valid Within General Relativity?

I've already posted these, but some disappeared after the last shuffle.

Thanks
