Fortune’s Formula: The Untold Story of the Scientific Betting System That Beat the Casinos and Wall Street
William Poundstone

A book about the mathematical aspects of gambling, whether it be on Wall Street, or in the casino, this is a smart, playful book full of an eccentric mix of gangsters, MIT professors and business people who have used a variety of methods to get rich by playing the odds. Poundstone is a great writer — all his works are worth tracking down. Here he takes a complicated mathematical idea, explains it simply, and tells the story through compelling real life characters.
A much better book than the over hyped Bringing Down the House.
Recommended for the enthusiast.
