The Dirac matrices (more commonly called gamma matrices) are a set of matrices introduced by Paul Dirac in his formulation of the Dirac equation.
They are fundamental in quantum mechanics and quantum field theory, especially for describing spin-½ particles such as the electron.
Paul Adrien Maurice Dirac (1902–1984) was one of the greatest theoretical physicists of the 20th century. He made groundbreaking contributions to quantum mechanics and quantum electrodynamics, and is regarded as one of the founders of modern physics...
