Book Overview

Let the puzzlist beware: Mathematical Bafflers will disappoint those seeking the simple, straightforward, drudge-rewarding problem: it will delight those who have despaired of a truly challenging collection of mind-teasers. Beginners are advised to look elsewhere - the 158 conundrums offered here were designed by experts for experts - and many experts were, simply, baffled.Mathematical Bafflers gathers the prime problems from twelve years of the esteemed weekly Problematical Recreations which appeared in Aviation Week and Electronic News - periodicals read by mathematicians, engineers, computer programmers, and over the years, by serious puzzlists who heard about the special section. To keep the quality at a peak, Angela Dunn and a team of mathematicians invented their own puzzles and gleaned the best submissions from an enormous reader response. Criteria were conceptual originality, ingenuity of approach, elegance of solution, with preference given to the kind of puzzle more vulnerable to a flash of inspiration than mere persistence. Categories include algebra, geometry, diophantine equations, logic and deduction, probability, insight, and number theory. Each chapter provides solutions to all problems plus a selection of correspondence with readers containing complaints, pleas, commentary, and further speculation. Original woodcut illustrations add to the charm.Advanced mathematical skills are only sporadically required - the majority of problems are accessible to anyone wanting the challenge. Those mentally fit enough to find 1,000 consecutive nonprime numbers (page 164) or discover on what days of the week the first day of a new century can fall (page 210), apply within; all others enjoy the bafflement anyway.

Good fun.

It's not bad of a book. Many are well-thought out, and there are lots of creative pictures. The problems are challenging but not too challenging for anyone who is mathematically mature. There are solutions to every problem, but my complaint is that some of the solutions are not well-explained. Either I get it or don't, the "don't" part is where I have to forget about the problem as "trivial" and move on. There are not that many of them thou. A few problems posed in the book are pretty bad such as the age problem in page 18. That age problem on pg. 18 could have been solved much easier had the problem be rephrased (or maybe more insight in the solution page). Another problem on pg. 20 can be solved by ordinary physics formula of Newton's Law with s = (.5)at^2. After I solved the problem and checked the solution, I was surprised the author didn't take the route that I took. Of course, my way is lengthy but correct. That brings up another complaint: try to be multidimensional when offering solutions like how the author was when in Four Fours (which was extremely nice and very friendly). Anyhow, it's a good book at a very cheap price.

Fun little book!!!

I agree with the first reviewer! The problems are fun to read and think about. Unlike many problem books that state problems in a long-winded and confusing style, this book contains a series of interesting puzzles that are presented in a nice brief, easy to read format. The drawings are cute as well! It was this book, and others like it, that helped spark my interest in mathematics and problem solving from a young age. Now I use puzzles of this type for my own students! They make nice extra credit problems on exams! :-)

Puzzles for problem solvers

I actually have the 1st edition hardbound book that is copyrighted in 1964. It is also 217 pages and must be identical to the new editions.This book is filled with puzzles that were chosen for "originality, elegance of solution, and imaginative appeal." "The book singles out problem themes and solutions calling for ingenuity rather than perseverance."The book is arranged according to the types of problems. Here's how the chapters are broken up: 1)Algebraic Amusements, 2)Geometric Exercises, 3)Solving in Integers, 4)Problems in Logic and Deduction, 5)Probability Posers, 6)Insight Puzzles, 7)Assorted Number Theory Problems.The problems vary from simple to difficult. Overall, there's a good selection of mathematical brain-teasers.
