Derek Muller dives into the “six degrees of separation” myth by unpacking the beautiful math of small-world networks—think Watts-Strogatz shortcuts, Granovetter’s strength of weak ties and Barabási’s hubs born from preferential attachment. You’ll see fun simulations of disease spreading, Strogatz’s viral fame, and even how the Prisoner’s Dilemma ties into why just one extra connection can dramatically shrink the world.

Along the way you’ll pick up a 60% off code for Incogni, meet Snatoms (magnetic molecule kits), and find links to try the demos yourself. Bottom line: even in a massive web of people, your choices and connections can change how quickly ideas, rumors or viruses zigzag across the globe.
