The adventures in this book occur in the areas of algebra and geometry: it covers the notion of numbers (rational, real, complex, algebraic), algebra (groups, finite fields, and linear algebra), and geometry (two and three dimensional geometry and topology). It's a short adventure, with the book just squeaking over 100 pages. Thus, in that time, not much of the mathematics is fleshed out. There are a handful of examples and exercises, but barely enough to get your feet (or brain) wet.
On the one hand, the book does provide a summary of some of the interesting tidbits of algebra and geometry. There is a decent description of group actions and a pretty good development of some of the basics of Euclidean, elliptic, and hyperbolic geometry. On the other hand, after reading the book, I felt somewhat bewildered. Why are these particular topics covered? What is the point? I felt like I just had the appetizer and was ready for the main course, only to be told, "Okay, here's the check." According to the preface, the purpose of the book is "to present mathematics as … a vast panorama of ideas, whose history reflects some of the most noble thoughts of mankind." I didn't see much of that, however, due to some typos, some imprecise mathematics (the definition of algebraic number, the definition of an exact sequence), and the lack of direction. Of course, I'm looking at this as a mathematician. Perhaps a high school student or undergraduate would get more out of it, or at least appreciate it more.
