Meet Glen Whitney. The 40-year-old Long Island native made a fortune working at a hedge fund, but he quit his job recently so he could pursue a dream he's been nursing for years. (Although the article doesn't indicate where he worked, it was Jim Simons's nerd-factory, Renaissance Technologies.) Whitney's lifelong—and as-of-yet unrealized—goal? He's hoping to open a math museum in the middle of Manhattan. Can't you just feel the excitement?

Institutional Investor's Alpha magazine released its ranking of the top 25 hedge fund managers today. You'll be happy to hear that even though most people ended 2008 on a gloomy note, a handful of men who were already worth billions made billions more last year thanks to their canny trading strategies or the fact they predicted (correctly!) that a major shakeout was headed our way. In first place was Jim Simons, the former math professor who started the hedge fund Renaissance Technologies and who earned $2.5 billion on the basis of his complex computer-driven approach to the market. In second place: John Paulson, who totally saw the housing market was going to hell in a handbasket, bet big as a result, and has $2 billion to show for his efforts.
