What Is Social Physics?

Several previous posts suggest that our Science of Cities is more like Biology than Physics but Social Physics has a long history. CASA’s Martin Austwick recently gave an impromptu review from Quetelet’s original definition to Comte’s rebuttal. Useful definitions from Stewart in the 1940s to Iberall in the 1980s.

Embracing Urban Evolution


describes a rather innovative approach to designing the organic city. Ten architecture offices in Holland and China built a city in relay through 10 stages effectively mirroring a process of organic emergence rather than a strict top down design. Click here for the article by Adrian Hornsby.

The Heart of the City

Written by Victor Gruen in 1964 who said “I can visualize a metropolitan organism in which cells, each one consisting of a nucleus and a protoplasm, are combined into clusterizations to form specialised organs like towns…..” He portrayed this idealised structure left & this influenced Walt Disney click here.
