Can the very thing that plagues a city also be the solution to its problems? Steven Johnson may have that answer. He is the author of the new book The Ghost Map that details the mystery of the Broad Street cholera outbreak in London in September of 1854. Steven writes The Urban Planet blog for the New York Times where he explores the most interesting questions about cities.
