Book Review: What If?

Those who know me or have followed the blog long enough know I'm a big fan of Randall Munroe, writer of the comic strip xkcd. He also published a series of articles called, "What If?" He looks at bizaare, absurd, and wonderful scientific questions and poses a scientific, reasoned answer. Looking at questions like "What if everyone who took the SAT guessed on every multiple-choice question? How many perfect scores would there be?" to "If you had a printed version of the whole of Wikipedia, how many printers would you need in order to keep up with the changes made to the live version?" he has entertaining and educational ways of looking at these problems. What If? is a great book that picks the best questions and answers and lays it out in an easily accessible format accompanied by amusing comics and doodles. Not just limited to science geeks, this book has something for everyone.
