Will Pearson and Mangesh Hattikudur may only be part-time geniuses, but they’re lifelong knowledge junkies. In college, a series of late-night conversations led them to co-found Mental Floss, an award-winning magazine and website. Along the way, they’ve written books, created board games, and put a lot of terrifically bad jokes on t-shirts. Part-Time Genius is their newest adventure, built on the premise that learning is much more fun when it doesn’t feel like a chore.
