To navigate complex physical environments, animals keep track of the spatial relations among objects using various reference frames, both body-based (e.g., left/right) and environment-based (e.g., east/west), but how these spatial representations interact remains unresolved.

We all understand that knowledge shapes the fate of business and the growth of nations, but few of us are aware of the principles that govern its motion. The Infinite Alphabet unravels the laws describing the growth and diffusion of knowledge by taking you from a failed attempt to build a city of...
