Albert Einstein, The equivalence of matter and energy was originally expressed by the equation m = L/c², which easily translates into the far more well known E = mc² in Does the Inertia of a Body Depend Upon Its Energy Content? published in the Annalen der Physik (27 September 1905) : "If a body gives off the energy L in the form of radiation, its mass diminishes by L/c²."

About Albert Einstein
Albert Einstein (14 March 1879 – 18 April 1955) was a Jewish German theoretical physicist, widely acknowledged to be one of the greatest physicists of all time. Einstein is known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Together, relativity and quantum mechanics are the two pillars of modern physics. He won the 1921 Nobel Prize in Physics for his explanation of the photoelectric effect.
