Nassim Nicholas Taleb has devoted his life to immersing himself in problems of luck, uncertainty, probability, and knowledge, and he has led three high-profile careers around his ideas, as a man of letters, as a businessman-trader, and as a university professor. Although he spends most of his time as a flâneur, meditating in cafés across the planet, he is currently Distinguished Professor of Risk Engineering at New York University’s Polytechnic Institute. His work has been published in thirty-three languages.
