This book was originally written as a textbook (for a math-for-the-non-mathematician type course). It can be used as one (though as a textbook it's a bit dated), read cover-to-cover for edification and pleasure (the style is a bit more instructional than the average popular math book), or dipped into here and there for the topics the reader personally finds interesting. With well over 500 pages of fairly small print, there's a lot here, covering a wide variety of topics, with (it seems to me) particular emphasis on history, geometry (of various kinds), and applications of math to physics. If you leaf through the book, you'll find some pages of nothing but text, some pages full of geometrical diagrams, some of equations and formulas, and even a few Renaissance paintings (in the discussion on mathematical perspective). With so much here, readers will probably find some parts more interesting than others--though which parts are the interesting ones may be a matter of personal opinion.
