Laura Overdeck is the author of Bedtime Math and Bedtime Math 2: This Time It's Personal. Laura knows a thing or two about numbers. As a kid, she sat and memorized perfect squares for fun, before it was cool. And as a mom, she (along with her husband, John) decided to give their three children math problems alongside bedtime stories, and soon Bedtime Math was born. Laura holds a BA in astrophysics from Princeton University and an MBA from the Wharton School of Business. When not playing with numbers, Laura pursues her other interests, which include chocolate, wine, extreme gravity stunts, and LEGO Mindstorms. Find out more at bedtimemath.org.
