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, Virginia. After studying physics at Christopher Newport University, he got a job building robots at NASA 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.
