I agree with the one star rating; if someone runs a query on each term (in this book), say in mathematica/wiki etc., and then concatenates the defintions together - the outcome will resemble this book very closely. Well, may be that is an overstatement, but you get the point!Horrible book for someone who looks for some intuition/motivation. It may be a great book for a hardcore mathematician who can gather inspiration from absolute abstraction. Not for a geometric-intuition-searching soul.
