3.0 out of 5 stars
Nice pictures --- at least one significant factual error
I enjoy this serious, because often the illustrations are well chosen. However, on page 26 the book states that pi is equal to 22/7. Since pi is an _irrational_ number it can not be expressed as the ratio of any two integers. Pi is only approximately equal to 22/7. This is an extremely important mathematical fact, so the error is a disconcerting one.
