“This is the "burglar-alarm" theory of bioluminescence: by turning on its lights, an animal may create enough of a scene to draw the attention of its predator's predator, and thereby perhaps save itself. The corollary of the burglar-alarm theory is the minefield theory. It says the reason so many animals tend to hang motionless in the deep, even fish, is to avoid setting off light explosions that would expose them to their enemies - their predators or their prey. Life in the midwater, in this view, is a tense affair (though the denizens do not know it) in which everyone is waiting stealthily in the dark, moving slowly if at all, watching and waiting for someone to turn on a light and for something to happen.”

“Historically, cities were built on rivers or natural harbors to ease the flow of goods. But these days, since shipping costs have declined and service industries have risen, what counts most is the flow of ideas.
The quintessence of the vibrant city for Glaeser is Wall Street, especially the trading floor, where millionaires foresake large offices to work in an open-plan bath of information. "They value knowledge over space -- that's what the modern city is all about," he said. Successful cities "increase the returns to being smart" by enabling people to learn from one another. In cities with higher average education, even the uneducated earn higher wages; that's evidence of "human captial spillover.”
