# Paul Dirac

## Collection by Mike Page

One of the greatest mathematicians and physicists of all time. An English theoretical physicist who made fundamental contributions to the early development of both quantum mechanics and quantum electrodynamics.

The Dirac Equation describes fields corresponding to elementary spin-½ particles (such as the electron) as a vector of four complex numbers (a bispinor), in contrast to the Schrödinger equation which described a field of only one complex value.

A fabulous biography of the great man.

An illustration of the monopoles shown as large spheres residing at the ends of a Dirac string. The dipoles are represented as dumbbells of magnetic charges and the Dirac string corresponds to a string of overturned dumbbells shown in dark.
