The achievement of Einstein's Law

Ernest Walton

In 1932, the English scientists C.D.Cockcroft and E.T.S.Walton tested the validity of Einstein's law in practice, he deliberately bombard the lithium with a high-speed proton that was composed of alpha particles and a large amount of energy. The previous nuclear reaction was associated with a mass loss of 0.0186 atomic mass units.
E.T.S.Walton was found that the amount of energy emitted from the reaction is equal to the amount of energy that can be calculated from Einstein's equation, so Einstein's law was proved and the mass conversion potential
