The Dirac equation is a fundamental equation in quantum mechanics and quantum field theory that describes the behavior of fermions, such as electrons and quarks, that have spin-½. It was formulated by the British physicist Paul Dirac in 1928 as a way to reconcile the principles of quantum mechanics with special relativity. The equation incorporates both the wave-like nature of matter and the relativistic effects of high velocities.
