Veritasium dives into the beautiful math behind six degrees of separation and small-world networks, unpacking shortcuts, the strength of weak ties, and how hubs form through preferential attachment. With interactive simulations and real-world examples—from disease spread to viral memes—you’ll meet the big names (Watts, Strogatz, Barabási) and see why a few key connections can shape the whole system.
Along the way, Derek Muller explores what the prisoner's dilemma teaches us about cooperation, shows how individual behavior ripples through global networks, and even points you to cool tools, book recs, and hands-on simulations. Sponsored shout-outs and nods to the all-star team behind the scenes round out this fast-paced look at why we really are all only a few steps apart.
