From NobelPrize on Twitter: In developing quantum mechanical theory, physicist Paul Dirac, born #OTD, predicted that all matter has a kind of mirror image - antimatter. Dirac's theory would later be proved experimentally. He was awarded the Nobel Prize in 1933 which he shared with Erwin Schrödinger. https://twitter.com/NobelPrize/status/1159345255101227008/photo/1
