Albert Einstein (1879-1955) wrote the famous formula of mass-energy equivalence of “E=mc2” or “energy equals mass times the speed of light (squared).” Chocolate—the chocolate bars are often in squares—gives people energy, and the formula is jocularly given as:

*“Energy equals milk chocolate squared.”*

“Energy = Milk Chocolate Squared” has been cited in print since at least 1997.

Wikipedia: Mass-energy equivalence

In physics, *mass–energy equivalence* is a concept formulated by Albert Einstein that explains the relationship between mass and energy. It states every mass has an energy equivalent and vice versa—expressed using the formula

*E = mc2*

where *E* is the energy of a physical system, *m* is the mass of the system, and *c* is the speed of light in a vacuum (about 3×108 m/s). In words, energy equals mass multiplied by the speed of light squared. Because the speed of light is a very large number in everyday units, the formula implies that any small amount of matter contains a very large amount of energy. Some of this energy may be released as heat and light by chemical or nuclear transformations. This also serves to convert units of mass to units of energy, no matter what system of measurement units used.
