Dirac, known for his groundbreaking contributions to physics, revolutionized our understanding of quantum mechanics and special relativity. His Dirac equation, which incorporates both concepts, predicted the existence of the electron’s antiparticle, later confirmed as the positron. Dirac’s work introduced key concepts such as spin, the Dirac field, and the Dirac sea, profoundly shaping modern physics. His use of Feynman diagrams and Dirac matrices as mathematical tools further advanced the understanding of particle interactions and special relativity.
