The Joy of X: A Guided Tour of Math, from One to Infinity by Steven Strogatz

4.0

I learned more about the "why" of calculus in this book than I did in a full year of AP Calculus in high school. It made me want to break out my old text book to rediscover the "how."

That said, the book is a very quick read (took me about 4 hours to finish, give or take) and skims the surface of a wide breadth of topics rather than delving into a few. A background in higher math is helpful if only for grasping concepts like vector calculus.
