E = mc2
An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself. (See relativity.)
Notes for E = mc2
Because the speed of light is a very large number and is multiplied by itself, this equation points out how a small amount of matter can release a huge amount of energy, as in a nuclear reaction.
