And, again, there's the puns that you can try out onįor those interested in getting a feel for what math is about, there's actually a great secret revealed inside the book - just what makes something a geometry. If you're a math teacher, this book can come in handy in providing was to visualize some very odd concepts in math. (I recommend Rudy Rucker's book =The 4th Dimension= for those who want to do more thinking about the 4th Some =real= exploring as opposed to this travel guide.

I can see this book as inspiring kids to learn more about strange concepts in math, but it would be nice to have a list of followup books for doing The puns), but then my favorite math book, =Godel, Escher, Bach=, was given to me when I was 12, and I grew into it over the years through rereading it and learning I think this book would be a great gift for a child who's interested in math - sure, they won't understand alot of it (and they'll miss many of This book is more like a travel brochure - letting you know what exciting sights are to be found in the strange lands of Geometry - but not giving you much of anĮxperience of what's there.

And, being a physics major in my undergrad life, I wasn't thrown off by the veering into modern physics topics. Got plenty of math jokes to add to my arsenal), and some of the descriptions are somewhat confusing - the only reason I knew what was going on is that =I knew= all However, as a math grad student, I found the treatment too shallow, the puns too egregious (especially when I saw them coming) and too unrelenting (though now I've

Geometry, in which there are and infinite number of line parallel to a particular line, all going through the same point (as opposed to the usual one parallel line) and on and Interacting in specific ways discrete binary geometries, which described digital encoding and the error-correcting codes used in things such as CDs and DVDs hyperbolic Ian Stewart's =Flatterland= is about all sorts of geometries that mathematicians play in: finite projective geometries, in which there are a finite number of points and lines, Though =Flatland=, by Edwin Abbott^2 100 years ago, was exclusively about 2 things: satirizing Victorian English society and explaining a 4th Euclidean dimension, Flatterland : Like Flatland, Only More So by Ian Stewart
