The surprising math of cities and corporations Geoffrey West on

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.)
