Ever wondered how we’re all just a few clicks away from anyone on Earth? Derek Muller dives into the “six degrees of separation” mystery, showing how tiny random “shortcut” links in a network turn it into a small world. You’ll learn why weak ties pack a surprising punch, how super-connected hubs emerge, and why diseases (or cat videos) spread faster than you think.
Along the way, meet the legends—Duncan Watts, Steve Strogatz, and Albert-László Barabási—and tinker with interactive sims for disease outbreaks and network growth. It’s a fun mash-up of math, history and game theory (hello, Prisoner’s Dilemma) that proves our world is smaller—and more interconnected—than you ever imagined.
