One of the remarkable things about slums is that they do develop their own social organization and economy and even culture that is, on some level, functional and in some cases, remarkably resilient. This is kind of amazing.
When you look at a city, you know, it looks so unique. You feel this kind of uniqueness, you know, and especially if you go from a big city to a small city or if you go from one country to another. Cities look very different, often. They even feel very different. You know, and they are, of course. They certainly are.
Cities are just a physical manifestation of your interactions, our interactions, and the clustering and grouping of individuals.
We form cities in order to enhance interaction, to facilitate growth, wealth creation, ideas, innovation, but in so doing, we create, from a physicist's viewpoint, entropy.
Sometimes, I look out at nature and I think, 'Everything here is obeying my conjecture.' It's a wonderfully narcissistic feeling.
