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?
