Simply Dirac

The physicist who brought quantum mechanics and relativity together.

Paul Dirac was one of the great theoretical physicists of the twentieth century, a remarkably quiet and unconventional man whose ideas changed our understanding of the universe. In Simply Dirac, historian of science Helge Kragh offers an accessible introduction to Dirac’s life and revolutionary contributions to modern physics. Kragh explains how Dirac helped develop quantum mechanics and created an equation that united quantum theory with Einstein’s special theory of relativity. His work led to one of the most remarkable predictions in physics: the existence of antimatter. Along the way, Kragh introduces readers to Dirac’s unusual personality, his relationships with other leading scientists, and the intellectual world in which modern physics was taking shape. The result is a fascinating portrait of a scientist who believed that mathematical beauty could reveal deep truths about nature.
