Manuel Lima: How knowledge grows


If you dig long enough, you are sure to unearth a treasure.

For the past 10 years, Manuel Lima has been studying how it is people organize and visualize information. Across cultures, Lima found that ideas are mapped in the form of trees. Be it family ties, ranks of hierarchy, or (the perhaps more obvious tree of knowledge), these concepts were displayed with branches shooting out from a core root.

Listen to Manuel Lima discuss humanity’s desire to map out knowledge in this TED Talk that took place earlier this year.
