- But Dirac's prediction of antimatter stands alone in being motivated solely by faith in pure theory, without any hint whatever from data, and yet revealing a deep and universal property of nature. The positron illustrates the general principle that all particles that have a conserved attribute, such as charge, have corresponding antiparticles.

Paul Dirac realised that because the electron was very light and moved very quickly, special relativity needed to be incorporated into the equation to explain this fine structure. Dirac produced a more complicated wave equation that revealed the electron’s true character. First, it predicted that electrons had spin,

In 1928, British physicist Paul Dirac wrote down an equation that combined quantum theory and special relativity to describe the behaviour of an electron moving at a relativistic speed.
Perhaps the most amazing thing about antimatter is that it was conceived of at all. In 1928, British physicist Paul Dirac set out to solve a problem: how to reconcile the laws of quantum theory with Einstein's special theory of relativity.
