There are some extremely powerful and useful concepts only introduced here. This requires more study to really absorb. As I understand it one of the implications of this work is that innovation is key to the survival of cities, but doesn't help much for companies.
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.
