The idea that science moves forward by carefully peeling back layers of the onion of truth, one by one, in a deliberate fashion, is so prevalent that it borders on cliche. But the truth is that running scientific experiments often feels more akin to dipping a cup into a bottomless well of information: each new study simply raises more questions than it answers. Although scientific knowledge is vast, ignorance, or what's left to learn, dwarfs what we think we know. Exploring this boundless frontier, neurobiologist Stuart Firestein explains how ignorance, rather than facts, drives science.

Stuart Firestein is the Chair of Columbia University's Department of Biological Sciences where he studies the vertebrate olfactory system, possibly the best chemical detector on the face of the planet. Dedicated to promoting the accessibility of science to a public audience Firestein serves as an advisor for the Alfred P. Sloan Foundation's program for the Public Understanding of Science. His popular course at Columbia University served as the basis of his new book Ignorance: How it Drives Science published by Oxford University Press.
