CRC Concise Encyclopedia of Mathematics

It seems to me that [Weisstein's] encyclopedia inaugurates a new era for two reasons: one, as the suthor says, this book lives and breathes hand-in-hand with the Internet. This book's ease of reference, despite a lack of index due to size limitation, and interactive features place it squarely and successfully in this new age. The second reason why the book is a "first" in the technology age is that CAS are used extensively by the author, and Mathematica codes are included in this new edition. SIAM Review, Vol. 46 Praise for the first edition: "This extraordinary volume beautifully captures many of the discoveries in mathematics in a readable and authoritative fashionWhat is truly exceptional is that this encyclopedia is the product of a single dedicated and talented authorThis book is an excellent resource for both teaching and research libraries" -Journal of Mathematical Psychology "I cannot praise the work too highly: Its vast scope and readability make the encyclopedia a great success." - Robert Dickau "Impressive...I found it very interesting and spent time reading about a variety of topics for which I had very little background or knowledge...A valuable source of information..." - W.E. Schiesser, Lehigh University "Users will actually look forward to picking it up one of the more important tools that will help college students actually grasp important mathematical concepts, written in such a way as to invite students to return to it time and again to discover that they really can understand mathematics and apply its concepts to derive solutions to practical problems."
