What If? Serious Scientific Answers to Absurd Hypothetical Questions by Randall Munroe

BATB score: 7/10

When a robotics engineer at NASA quits to scientifically answer the world's craziest what ifs (absurd hypothetical questions) with drawings of stickman comics.

Personal Favourite: "If you call a random phone number and say "God bless you," what are the chances that the person who answers just sneezed?" [calculation hint: 200 sneezes per person per year.]

Best for: reading on the go-go-go (on the potty, in the elevator, waiting in the lobby, in between naps, etc)

Best as: a decent and thoughtful enough gift that gives the giver 2+ points on the intellectually considerate scale

P.S. of all the what ifs in the book, there was nothing on transporting a T-Rex via the Helicopter Rope Suspension Technique as per illustrated on the book's cover
