the equation, E=mcª is merely a derivation of the formula for kinetic
energy, which is K=mvª. Thus, E in his equation is merely the kinetic
energy of the mass moving at the speed of light. the equation for
kinetic energy has been known for centuries.
Einstein did alot of stuff. He was a German. How can you look at
the guy and not see he's of the German race? you must be really
stupid.
