Summary
This Veritasium video dives into the “six degrees of separation” idea by simulating how tightly connected our world really is. It walks you through network shortcuts, the famous “strength of weak ties,” and even models how fast diseases can spread. Along the way you’ll meet network hubs, see how preferential attachment builds “rich-get-richer” structures, and find out how your own connections can reshape global dynamics.
Big shout-outs go to pioneers like Duncan Watts, Steve Strogatz, and Albert-László Barabási for inspiring the math and stories behind these simulations. You’ll also get links to play with the models yourself, learn about the Prisoner’s Dilemma in networks, and discover how tiny changes in behavior can have massive ripple effects.
