Abstract:
Introduction In 1900, Henri Poincaré noticed that the radiation energy has a mass m, equal to the energy divided by the square of the speed of light: m = E/c2. Later this relationship used by Einstein in his work on the principle of relativity. Since then, the claim that the mass can generate energy and vice versa has been called "The principle of the equiv alence of mass and energy," and became a fundamental, which prohibit criticism.
