Something Strange Happens When You Trace How Connected We Are

Veritasium unpacks the magic of six degrees of separation by journeying through small-world networks. You’ll discover how Watts and Strogatz’s shortcuts and Granovetter’s “strength of weak ties” prove that we’re all just a handful of links away, why Barabási’s hubs emerge through preferential attachment, and how quickly diseases (or ideas) can zip across the globe.

Packed with playful simulations—from disease spread to the Prisoner’s Dilemma going viral—you’ll see how simple rules shape massive networks and how your own connections can tip the scales, proving that even a tiny nudge in behavior can echo far beyond your circle.
