TL;DR

Derek Muller dives into Paul Dirac’s mind-bending journey from wondering if “negative energy” could exist to rewriting quantum mechanics—first spotting the Schrödinger equation’s blind spot, then crafting the Dirac equation that predicted a whole anti-universe. Along the way we meet the “strangest man in physics,” learn how antiparticles (hello, positron!) naturally emerge as solutions traveling backward in time, and glimpse the eerie idea of an entire mirror-world of antimatter.

Packed with expert interviews, archival treasures from FSU and Caltech, and clear breakdowns of Klein–Gordon, Heisenberg’s uncertainty, and the Dirac equation itself, this video turns one of modern physics’ saddest chapters into a thrilling detective story about the birth of antimatter.
