What If 2

A delightfully nerdy follow up to his bestselling book, Randall Munroe examines absurd hypothetical questions with all the scientific precision and good humor it deserves in what If? 2. Munroe throws bizarre physics problems, outlandish what if at you, and answers them in an entertaining, enlightening way. For curious minds, this book is perfect, it is a fun, imaginative book on the possibilities of the universe.
