Clearly passionate about math, Weisstein, an astronomer, began compiling this one-man labor-of-love reference about 14 years ago during his college days. Topics reflect the author's interests, as he says, his "own random walk through mathematics," rather than a fixed set of criteria. Differing from other math dictionaries, this one contains extensive cross referencing to related entries as well as internet sites; the entries contain both standard and popular references; and the abundant examples include explicit formulas and derivations. Weisstein has added about 3,600 new entries to this second edition (which is about one-third larger than the first, published in 1999), updated everything (including bibliographies), and enhanced many entries by incorporating Mathematica commands (for performing calculations and producing graphical displays and illustrations). At more than 3,000 pages (necessarily thin paper, to fit in one volume), this work is a unique reference and a terrific value pricewise.

This four-volume reference explains mathematical concepts and provides a historical overview of the field in language appropriate for middle school through high school students, or for general readers. Separately indexed, each volume is about 220 pages and devotes 35 pages or so to an identical glossary and topic list probably a useful feature for student readers who might not make the effort to refer to a separate volume. Entries are alphabetically arranged and discuss topics related to the uses and effects of math in daily life; its role as a tool for measurement, data analysis, and technological development; important people; and careers. Each entry is signed and includes a brief bibliography. Entries range from a half page to several pages and are abundantly illustrated.

Intended for curious high school students, this two-volume encyclopedia clarifies 80 mathematical topics and their practical utility for study. Each entry begins with an overview of the subject, defines the fundamental concepts and terms, reviews the history of discovery and development, and describes several real-life applications. Topics include algebra, calculus, fractals, game theory, logarithms, music, proportion, rounding, statistics, trigonometry, volume, and word problems. Black and white photographs are provided.
