We form cities in order to enhance interaction, to facilitate growth, wealth creation, ideas, innovation, but in so doing, we create from - from a physicist's viewpoint, entropy, meaning all of those bad things that we feel are engulfing us.

Cities tolerate crazy people. Companies don't.

When people come together, they become much more productive.

The paradigm of physics - with its interplay of data, theory and prediction - is the most powerful in science.

You could not have evolved a complex system like a city or an organism - with an enormous number of components - without the emergence of laws that constrain their behavior in order for them to be resilient.

Cities are obvious metaphors for life. We call roads arteries and so forth.
