{{cquote|''This theory of equivalence of mass and energy has been beautifully verified by experiments in which matter is annihilated - converted totally to energy: An electron and a positron come together at rest, each with a rest mass <math>m_0</math>. When they come together they disintegrate and two gamma rays emerge, each with the measured energy of <math>m_0c^2</math>. This experiment furnishes a direct determination of the energy associated with the existence of the rest mass of a particle''|||Richard Feynman}}
