Paul Dirac was among the greatest scientific geniuses of the modern age. One of Einstein's most admired colleagues, he helped discover quantum mechanics, and his prediction of antimatter was one of the greatest triumphs in the history of physics. In 1933 he became the youngest theoretician ever to win the Nobel Prize in Physics. Dirac's personality, like his achievements, is legendary. The 'Strangest Man' uses previously undiscovered archives to reveal the many facets of Dirac's brilliantly original mind.
