By Zack Quaintance — Department of Mind-Blowing Theories is the new book from cartoonist Tom Gauld, a poignant and often hilarious storyteller who in this work has turned his ample talents toward the bite-sized and satirical. The book is a compendium of single-page cartoons done for New Scientist, and, as such, they entirely skew that profession. It’s not a linear story of any sort, but, then again, that’s probably not want anyone is expecting when they pick this book up.
