In Something Weird Happens When E = –mc², Derek Muller walks you through Paul Dirac’s wild journey from spotting a flaw in the Schrödinger equation to formulating his eponymous Dirac equation—and how that led to the jaw-dropping prediction of negative energy states and antimatter. You’ll meet Dirac (“the strangest man in physics”), learn why antiparticles can be thought of as electrons traveling backwards in time, and get a taste of the “anti-world” he envisioned.
Along the way, the video digs into the Klein–Gordon equation, Heisenberg’s uncertainty principle, and the real-life discovery of the positron—plus shout-outs to all the experts, archives, and cool sponsors that made the deep dive possible.
