13h 1min, jan 1, 1930 y - Paul Dirac
Description:
British physicist is trying to combine relativity and quantum mechanics. He succeeds, and the relativistic quantum equation is called the Dirac equation as a consequence. He notices that his equation predicts the existence of "negative" states for the electron and proton, and he thus predicts the existence of antimatter.Added to timeline:
