Can you really reach anyone in six steps? This video dives into the beautiful math of “six degrees of separation,” showing how tiny shortcuts and weak ties in a network collapse vast social distances. It traces Duncan Watts’ small-world model, Steve Strogatz’s clear storytelling, and Albert-László Barabási’s insight on network hubs to reveal why most of us are just a few clicks (or handshakes) away from anyone else.
Beyond theory, simulations illustrate how quickly diseases can sweep through these webs, how preferential attachment grows mega-hubs, and even how classic dilemmas play out in connected societies. The takeaway? Understanding networks isn’t just fun math—it’s a roadmap for influencing everything from viral videos to global pandemics.
