Something Strange Happens When You Trace How Connected We Are

This video unpacks the magic behind “six degrees of separation,” showing how small-world shortcuts, weak ties, and network hubs (thanks to Watts, Strogatz, Barabási, and Buchanan) connect us all. You’ll see quick demos of disease-spread simulations, preferential attachment models, and even a dive into the Prisoner’s Dilemma to prove how tiny tweaks in connections can have huge ripple effects.

Alongside the science, Derek Muller plugs Incogni (code veritasium for 60% off), his Snatoms molecular kit, and a weekly newsletter. Chapters guide you from network theory basics to real-world impact—proving that your own behavior can literally change the world’s wiring.
