What if all of the water in the world disappeared? Are plastic dinosaurs actually real dinosaurs? Could raindrops shatter a windshield? Part webcomic, part scientific study, Randall Munroe’s popular What If? column answers these and other hypothetical questions by crunching numbers, analyzing scientific theories, and drawing mini comics. In his new book What If? Serious Scientific Answers to Absurd Hypothetical Questions, he revisits his favorite questions — with expanded answers, diagrams, and never-before-seen comics — and includes a list of the “weirdest questions” people have submitted over the years. A former NASA employee, Munroe is now a full-time expert, cartoonist, and blogger at his “amazing” xkcd blog.
