In developing quantum mechanical theory, physicist Paul Dirac, born on this day, predicted that all matter has a kind of mirror image - antimatter. Dirac's theory was revolutionary, and later would be proved experimentally. He was awarded the #NobelPrize in 1933 which he shared with Erwin Schrödinger. Dirac was only 31 years old when he received the award. Video: A short glimpse of Professor Paul Dirac after his arrival in Stockholm for the Nobel Prize award ceremony held on 10 December 1933. ©

#CultureScientifique | C’est à tout juste 26 ans, en 1928, que Paul Dirac formule l’équation qui porte son nom. Et il lui a fallu une année entière pour y parvenir ! Dans ce 9e épisode des équations Clefs de la #physique, découvrez l’histoire de l’équation de Dirac, qui permit de prédire l’existence de l’#antimatière… Une véritable révolution ! | CEA
