Albert Einstein

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former. -Albert Einstein

A physical system has a property called energy and a corresponding property called mass; the two properties are equivalent in that they are always both present in the same (i.e. constant) proportion to one another. Mass–energy equivalence arose originally from special relativity, as developed by Albert Einstein, who proposed this equivalence in 1905 in one of his Annus Mirabilis papers entitled "Does the inertia of an object depend upon its energy-content?"The equivalence is described by the famous equation:
E = mc^2 \,\!
