The surprising math of cities and corporations: Geoffrey West on TED.com

Posted by: Emily McManus

Physicist Geoffrey West has found that simple, mathematical laws govern the properties of cities — that wealth, crime rate, walking speed and many other aspects of a city can be deduced from a single number: the city’s population. In this mind-bending talk from TEDGlobal he shows how it works and how similar laws hold for organisms and corporations. (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland. Duration: 17:33.)

    Extraordinary! I reel from the info in this talk. I wanted to study mathematics in college, did something different, and now the power of math fascinates me yet again. I still gravitate towards popular books where statistics and math cover tilting points, innumeracies, and so on. With my low tolerance for speeches (developed by watching too much broadcast news), I found myself hanging onto the speaker’s every word and stunned by his unravelling of each discovery. Thankfully I found this talk during my high intellectual biorhythm, so each idea had amazing clarity. I appeciate the offering of this lecture.

    This seems inane… true to how he started saying the research was done by others and he was just the BSer…this is long winding, confusing and abstract with no real learnings. Just one point he is proving, all economics/nations/growth follow the universal ‘s’ curve; nothing new or original. Disappointed.
