TED: Mapping ideas worth spreading | Eric Berlow and Sean Gourley

The video explores the study of complex networks through TEDx talks. The speakers discuss their methods of collecting and analyzing data from 24,000 talks across 147 countries, using natural language processing to uncover the mathematical structure of ideas. They demonstrate how these ideas are interconnected globally, forming a network that reveals emergent topics and creative content. The analysis highlights the limitations of traditional algorithms and emphasizes the potential of using network structures to explore complex ideas and conversations.
