Randall Munroe is perhaps better known as xkcd guy. His web comic is pretty popular, especially with scientists.
It's a beautiful book because it's all about how simple the world truly is when pretentious folks aren't trying to get jollies off by pretending that it's complicated. I haven't seen its contents yet, but knowing xkcd guy, it should be an insightful, fascinating explanation of the world around us in a delightful read filled with fun-but-meaningful illustrations.
