Dirac established the most general theory of quantum mechanics and discovered the relativistic equation for the electron, which now bears his name. The remarkable notion of an antiparticle to each fermion particle – e.g. the positron as antiparticle to the electron – stems from his equation.

WebbThe Dirac equation is invariant under charge conjugation, defined as changing electron states into the opposite charged To do this the Dirac spinor is transformed according to. Of course a second charge conjugation operation takes the state back to the original . Applying this to the plane wave solutions gives which defines new positron spinors
