The Massachusetts Institute of Technology (MIT) is geek central, the greatest school of its type in the world. Along with Harvard, it dominates the city of Cambridge, across the river from Boston. MIT is a city within a city consisting of the campus but also the penumbra of gigantic, architecturally eccentric buildings in which live the high-tech companies that graze on the institute’s talent. Around Kendall Square, people shuffle along the streets lost in thought. In the cafes they read and write notes on yellow legal pads. This is where money meets IQ. It is not quite like anywhere else on Earth.
