Veritasium’s latest deep dive follows Paul Dirac’s wild ride from the broken Schrödinger and Klein-Gordon equations to his eponymous Dirac equation that dared to let E = −mc² be real. Along the way you’ll meet the quirkiest minds in physics, see why Heisenberg’s uncertainty principle matters, and find out how a theoretical glitch predicted the positron—and an entire “anti-world” where antiparticles zip backward in time.
With expert commentary from Graham Farmelo and Cumrun Vafa, this video uncovers the strangest chapter in modern physics, explores the discovery of antimatter, and challenges our instinct to always think of energy as positive. Strap in for a whirlwind tour of negative energy, anti-electrons, and the universe’s mirror image.
