This Veritasium video unpacks the math of “six degrees of separation,” showing how small-world networks emerge through shortcuts, weak ties, and hubs. You’ll see Watts’ small-world model, Strogatz’s viral network demos, and Barabási’s preferential attachment in action alongside simulations of disease spread.
Through real-world examples (even a Prisoner’s Dilemma twist), you’ll learn how a handful of connections can turbocharge information flow or epidemics—and how tweaking your own network behavior could literally change the world.
