All Lex Fridman Podcast coverage
Khabib Nurmagomedov says Islam Makhachev can pass Jon Jones, but age is already closing the window
Khabib makes the case for Islam Makhachev as a future GOAT, then immediately points to the thing that could beat him before another fighter does: the calendar.
Jensen Huang says NVIDIA will sell a few trillion dollars of computing over the next several years
The NVIDIA CEO turned a Taiwan walk-and-talk with Lex Fridman into a very expensive thesis about the future of compute.
Don Lincoln says the Higgs field turned on 10^-12 seconds after the Big Bang and gave particles mass
The Fermilab physicist gives the cleanest possible version of a very weird idea: mass, at least for elementary particles, arrived when the early universe cooled enough for the Higgs field to switch on.
Anthony Kaldellis says Diocletian ended Italy’s tax haven and made taxation the core of the Roman state
The Byzantine historian’s best line on Lex Fridman is not that Diocletian invented the deep state, but that he made the conquerors finally pick up the tab.
Khabib Nurmagomedov says he and Islam Makhachev don’t understand each other’s native languages
The former UFC champion used one tiny linguistic fact to explain why Dagestan is less a simple fight-factory stereotype than a mountain archive of peoples, faiths, food, and history.
Don Lincoln says Fermilab was two or three years from discovering the Higgs boson before CERN got there
The Fermilab physicist frames the Higgs discovery as a near miss, not a clean victory lap for CERN, and he has the machine numbers to make that sting.
Anthony Kaldellis says Rome’s three biggest disasters were the Arab conquests, the Seljuk conquest of Asia Minor, and the Fourth Crusade
The Byzantine historian’s Roman Empire is not a marble statue collapsing in 476, but a long-running state repeatedly injured by three fast, brutal shocks.
Andrew Scull says Nazi gas chambers were developed first to kill mental patients
The historian of psychiatry connects asylum overcrowding, American eugenics, California sterilization laws, Rockefeller-funded genetics research, and the Nazi T4 program into one grim family tree.
Don Lincoln says Maxwell's equations turned magnets and sparks into the internet
On the Lex Fridman Podcast, the Fermilab physicist makes the case that the weirdest, least practical physics is often the stuff that later rewires civilization.
Khabib Nurmagomedov says his father prepared him for Conor McGregor by making him lose judo matches at 15
On Lex Fridman’s podcast, Khabib turns his invincibility myth into something more annoying and more useful: repetition, discomfort, and losing early where nobody was watching.
DHH says Omarchy's Linux install world record is 45 seconds
David Heinemeier Hansson turns a Linux distro install time into a philosophy of overbuilt software, Elon Musk ambition, and mildly deranged stopwatch joy.
DHH says Omarchy's growth went vertical when it made Linux agent-first
The Rails creator argues that the Linux crowd’s hostility to AI is exactly why Omarchy can break out.
DHH says one person can now build the 5 percent of Premiere or Photoshop they need on Linux
The Basecamp co-founder’s real claim isn’t that every solo coder is Adobe now, it’s that cloning the part you actually use has become weirdly plausible.
Don Lincoln says galaxies with no dark matter are strong evidence dark matter is real
The physicist’s best pro dark matter argument is wonderfully backward: the missing stuff looks more real when you can find places where it’s missing.
Don Lincoln says the speed of light comes out of Maxwell's equations for electricity and magnetism
The Fermilab physicist makes the old physics story feel properly weird again, then uses it to defend basic research from the eternal question, what good is this?
Khabib Nurmagomedov says Islam Makhachev can overtake Jon Jones, Demetrious Johnson, and Georges St-Pierre, but time is running out
Khabib’s praise for Makhachev comes with the most Dagestani compliment possible: you can become the greatest ever, now hurry up because your body is betraying you.
Don Lincoln says we exist because the early universe had one extra matter particle per billion antimatter particles
The Fermilab physicist framed existence as the leftover scrap from a cosmic matter-antimatter wipeout, then admitted nobody knows what caused the imbalance.
Anthony Kaldellis says Byzantine Greek fire came in hand grenade form
The historian’s best detail on Lex Fridman was not just that Greek fire burned on water, but that the Romans apparently bottled the stuff and threw it at siege engines.
Don Lincoln says quantum field theory predicts dark energy 10^120 times too large
The Fermilab physicist puts a number on the vacuum catastrophe, and the number is so stupidly large it makes ordinary scientific failure look dainty.
Anthony Kaldellis says the Plague of Justinian probably did not kill half the Roman Empire
The historian's case is brutally practical: if half the empire died, why did Justinian's wars, taxes, and courts keep running?
Anthony Kaldellis says Roman families voluntarily castrated their sons to place them at the emperor's court
The Byzantine historian explains how castration was sometimes a family's smartest power move, not just a cruelty imposed on slaves.
Don Lincoln Wants You to Understand Why Time Is Weirder Than You Think
A Fermilab physicist walks Lex Fridman through the history of spacetime, and the most interesting part is what nobody actually understands.
Don Lincoln Has Spent 30 Years Looking for Dark Matter and Has Absolutely No Idea What It Is
The Fermilab physicist makes a compelling case for something he cannot find, cannot name, and cannot stop thinking about.
