I'll probably forget this book as quick as I read it. At 192 pages (with very little on a page) this is a book which you'll read in a very short time. I love reading popularising science books but this one left me with a feeling that there was just more to write about. Take the little section on why we measure angles in degrees and decided that a circle is 360 degrees. The book explains how it comes form the Babylonians but stops there. It would've been an interesting story to learn more but as with most other snippets of this book, the author explains the history and material in this book in a bit of a superficial way.
I'll keep the book for while, perhaps my kids when they're in their teens and happen to enjoy popularising science might enjoy it better than I did.
