What If?

Randall Munroe is the author of the popular webcomic xkcd and the science question-and-answer blog What If? Randall was born in Easton, Pennsylvania, and grew up outside Richmond. After graduating with a degree in physics from Christopher Newport University in Newport News, Virginia, he got a job building robots at NASA’s Langley Research Center. In 2006 he left NASA to draw comics on the Internet full time, supporting himself through the sale of xkcd t-shirts, prints, posters, and books. He likes candlelight dinners and long walks on the beach—very long walks. Lots of people say they like long walks on the beach, but then they get out on the beach, and after just an hour or two, they say they’re getting tired. Bring a tent. He lives in Massachusetts.
