#Mindscape , Episode 5: Geoffrey West on Networks, Scaling, and the Pace of Life
If you scale up an animal to twice its height, keeping everything else proportionate, its volume and weight become eight times as much. Such a scaling relation was used by J.B.S. Haldane in his famous essay, “On Being the Right Size,” to help explain certain features of living organisms. But scaling relations go much deeper than that, and they are often much more subtle than the volume going as the cube of the length. Geoffrey West is a particle physicist turned complexity theorist, who studies how features from metabolism to lifespan change as we adjust the size of an organism — or of other complex systems, from cities to computer networks. His insights have important implications for innovation, sustainability, and the best ways to organize life here on Earth.

👍 In this thread, Aaron Clauset reviews results on faculty hiring networks and the numerous correlates of prestige. A nice summary of a lot of work from our own collaboration and many others.

@davidlazer @thosjleeper @maya_sen @arthur_spirling I love this area of work, partly because it constantly draws in new people, who de novo hit on similar kinds of ideas. The tl;dr is that doctoral prestige is highly predictive of both faculty placement *rates*…
