Marshall Brain's How Stuff Works : How Much Does the Earth Weigh? (Marshall Brain's How Stuff Works)

Rating:
Summary: Now I know!
Review: Your interest in this book will depend upon how curious you are about the world around you. The people at HowStuffWorks have returned with another tome of difficult questions answered in an approachable way. (The only caveat is that the explanation does not always answer all parts of the question.)

It includes descriptions of how Caller ID works, how much "all the money in the world" is, as well as the immortal "Why is the sky blue," ending on the ambitious titular question.

This is an ideal bedside (or lav-side) book and if you are interested in trivia or how the world works, I recommend it without reservation.
