|Randall Munroe's self portrait|
Randall Munroe is the creator of the popular webcomic xkcd (no, you don't pronounce that, you spell it). It's simple in that it is typically comprised of stick figures, and complex in that it is usually about advanced sciences.
Personally, my favorite fact about this week's author is that Cassy and I went to the same college as him at the same time as him. One of my roommates dated one of his roommates, so I have that weirdly specific and totally tenuous connection to him. (Actually, when we met him at New York Comic Con last October, he remembered her after we reminded him of that fact, albeit a little vaguely. Either that or he's great at faking memory and very polite.)
He wrote What If? (and was interviewed by Stephen Colbert about it shortly before "The Colbert Report" ended) and it is something very unique. You'll hear more about it when we review it, but he took crazy questions from xkcd readers and answered them with a heaping pile of science, peppered with his style of illustrations. I can't wait to tell you more about it on Friday!
