Cities obey the laws of living things


Cities Obey the Laws of Living Things: The analogy of city as living organism is so established it's crossed into scientific inquiry.

To resolve this problem, Manoli and his colleagues “re-scaled” 100 cities around the globe, breaking them down into units they called pixels that could be more equitably compared across variously sized urban areas. The relationship between these variables follows the same curve for all cities, large and small, they found, and echoes Kleiber’s Law, a principle that emerges in biology when the sizes of animals are viewed in relation to their metabolic rates. The relationship is universal and independent of geographical, political, and historical differences, they say: Cities self-organize as they grow, naturally optimizing for energy flow and resource distribution, regardless of context and without central planning.
