Whodunit Math Puzzles
This is an excellent, non-threatening way to introduce math in the real world to children.Cal's adventures are short, and require problem solving skills that everyone needs to practice.This book is not just for the mathematically inclined. It is for children of all ages looking for a riddle to solve.

Excellent math puzzles for the middle school child
My son likes math puzzles, so when he saw that this book was available, he purchased it through the scholastic books program at his school. He enjoyed it and so did I. It consists of 22 problems presented in the form of math puzzles. Each puzzle is roughly four pages in length and solutions to all are in the back of the book. The writing is well done and the problems posed are at the middle school level.
Most of the problems involve crimes and what is nice about the stories is that the problems blend so well with the situations. One of the main and valid criticisms of textbook problems is that they are so artificial. There is none of that here. The problems are fresh, interesting and present mathematics in a realistic light. If your children have an interest in math, then you should buy them this book. ... Read more

For a mixed audience
I think this book aims at a mixed audience with mixed success.For the puzzle solver, there is interesting background on some popular forms, but probably not enough puzzles.For someone with a background inmaththe exploration is too simple, (e.g. one paragraph of Godel) and for the computer scientist not enough exploration of algorithms.For the historian of science there are some new perspectives, but the history is not carried through. On the discussion of Labyrinths, I wish Danesi would have mentioned the book Labyrinths by Borge, and also alluded to the form in some churches.

Although the book may not be for the "specialist", there is quite a bit of fun for anyone here.For example I had been familiar with the Fibonacci series, but hadn't seen the Rabbit Puzzle before. Everyone has heard of the Mobius strip, but the Klein bottle was new to me (and I'd love to buy one).I had done mazes before, but the one by Lewis Carroll us fun.

Good start, but never becomes really challenging
Liar's Paradox has ten chapters covering 10 puzzles that mankind has created over its history.Each chapter covers a main puzzle, the historical and philosophical background behind it, and describes how each affected mathematics/science as people thought their way through the puzzles.Each chapter includes a set of follow up questions/puzzles, with a good answer section at the back.

One should note that while most of the chapters focus on math, others seem only indirectly related--for instance, one chapter is almost solely devoted to problems related to perception and psychology (such as two-tone pictures in which you can see both a vase and two people's faces), and other chapters are related to math only in extremely advanced ways--for instance, the Liar's Paradox may be a math problem for some, but at the level this book is written it doesn't really get past a discussion of logical paradoxes.

On that note, this book is written at the level of someone who vaguely remembers high school algebra (for instance, there is a fairly in depth discussion of what "exponents" are).For someone at that level, I think the book is excellent.The puzzles Mr. Danesi chooses are interesting and all described well.The puzzles at the end of each chapter are entertaining.

I think readers should recognize before they buy this book that it is probably not meant to be a brain-wracking, headache-inducing puzzle book, but rather a leasurely review of some of mankind's more interesting puzzles.Mr. Danesi has done a good job of accomplishing that. ... Read more
