Biggest Mysteries in Physics: Antimatter, Dark Energy & ToE - Don Lincoln | Lex Fridman Podcast #497
May 31, 2026 · 2:53:43
Particle physicist Don Lincoln joins Lex Fridman to unravel the biggest mysteries in physics, from antimatter and dark energy to the search for a theory of everything. Lincoln traces the history of unification from Newton to the electroweak force, explains the 2012 Higgs boson discovery, and dives into the baffling problems of why the universe has more matter than antimatter and why empty space's predicted energy is off by 120 orders of magnitude. He argues that practical progress—testing dark matter, measuring neutrino oscillations, and probing quantum gravity—will outpace grand theoretical leaps like string theory.

Jensen Huang: NVIDIA - The $4 Trillion Company & the AI Revolution | Lex Fridman Podcast #494
Apr 21, 2026 · 2:25:59
Jensen Huang, CEO of NVIDIA, explains how extreme co-design of GPU, CPU, networking, memory, and power enables AI scaling laws to continue, with pre-training, post-training, test-time, and agentic scaling driving demand for compute. He recounts the risky decision to put CUDA on GeForce, which nearly bankrupted the company but built an irreplaceable install base. Huang argues intelligence is being commoditized, while human character and purpose remain irreplaceable, and predicts AI will create more jobs by elevating roles like radiologists and programmers.

Vikings, Ragnar, Berserkers, Valhalla & the Warriors of the Viking Age | Lex Fridman Podcast #495

Historian Lars Brownworth explores the Viking Age, from the terror of Lindisfarne to the pragmatism of Ragnar Lothbrok, the blood eagle, and the religion of Valhalla. He explains how Viking longships and speed enabled raids, how the Great Heathen Army conquered England, and how Rollo founded Normandy. The conversation also covers Viking explorers reaching North America and the Varangian Guard in Constantinople.
