5.0 out of 5 stars Superb, December 15, 1999

By	Rajiv Eranki (Buffalo) - See all my reviews

Those who have read any of Martin Gardner's famous books know that he is the master at explaining difficult concepts in witty and precise language. This book is no exception! It's a great book to buy for children AND adults alike.

I encourage readers of this to purchase "Aha, Insight!" by the same author, and his "The (first,second,etc...) scientific american book of mathematical puzzles and diversions"

5.0 out of 5 stars Gardner at his best, explaining the unexplainable, December 8, 2005

By	Charles Ashbacher "([e-mail])" (Marion, Iowa United States([e-mail])) - See all my reviews (TOP 50 REVIEWER)

This is an ageless book for the people who love to think and do it well. A paradox is a situation where a supposedly valid chain of reasoning is performed and yet you end up with a conclusion that cannot be true. In many cases, the paradox is due to imprecise definitions of words or statements that are so broad in scope that they refer to themselves. For example, when a Cretan says, "All Cretans are liars." The scope of the sentence is so broad that it includes the sentence itself. Therefore, if the statement is true, the person saying it must be lying and if the statement is false, then the Cretan is telling the truth, which means that according to the statement he must be lying.
Many of the paradoxes are resolved by applying a simple analysis. Some of them are easily understood if presented in the appropriate context and no one does this better than Martin Gardner. He is truly unique in his ability to take a difficult mathematical concept and make it understandable. During his decades as the author of a regular mathematical column in Scientific American, he has done more to advance the progress of mathematics and science than anyone else in history. By turning so many young people on to mathematics, he is one of the intellectual grandfathers of hundreds of thousands of people.
This book is a delight and contains many problems that can be used in courses in mathematics, reasoning and philosophy. I strongly recommend it.

4.0 out of 5 stars Contradiction or not?, June 10, 2001

By	Pumpkin King - See all my reviews

Aha! Gotcha is filled with very different types of puzzles than aha! Insight, which has many problems to solve. This book just presents many fun paradoxes that make you use your head, and while some of them are problems you have to take some time to solve, most are short paradoxical situations that you can think about for a short while and then go on the next page. It is easy to read, and Gardner again shows his skill in explaining interesting phenomena in a clear and interesting way. All the problems are good exercises on logical thinking and introduces various concepts of mathematics and statistics without seeming like you're studying. It is insightful enough for adults, but I think children would be able to understand these concepts too if they are interested.
