Paul Adrien Maurice Dirac was one of the great physicists of the 20th century. He was a pioneer of both quantum mechanics and quantum field theory. The Dirac equation, which describes relativistic, fundamental particles such as the electron, and predicted the existence of anti-matter, stands as one of the most astonishing and beautiful equations of physics.

Paul Dirac came to St John's College, Cambridge in 1923 to read for a PhD in Mathematical Physics. He later become a fellow of St John's and held the Lucasian chair of Mathematics at the University of Cambridge.

The annual Dirac Lecture was established jointly by St John's College and the University of Cambridge's Department of Applied Mathematics and Theoretical Physics. This webpage contains the list of Dirac lectures, together with videos of many of their talks and other material.
