Genius!

I was failing all of my classes in high school. After I read this book I was able to use the power of paradoxes to confuse my teachers into giving me passing grades. For example, I stated "This sentence is false," sending my teacher into immediate confusion. OK, in all seriousness, this is a great book for learning to think creatively, and a lot of its short stories and ideas can be used as party tricks to entertain friends and annoy your teachers and professors. Pair this book with Aha! Insight and you have a complete set.

So smart, yet so easy to read.
Reviewed in the United States on May 22, 2012
The world is lesser without Martin Gardner in it.

Martin Gardner was a supremely intelligent mathematician with a real talent for explaining complex mathematical problems in a way that lay people could understand.

Gotcha! follows the same lines. It's kind of an odd book, in that the cartoony style is a little dated and it really looks more like a kid's book or a Young Adult book. Make no mistake, it's not, though young adults could certainly benefit and enjoy.

Gardner primarily approaches logical fallacies in this book. He uses the cartoons to walk you through exactly the wrong conclusion, then steps back and brilliantly deconstructs the argument so that you can see where your normal human condition fails you and why the unintuitive answer is the mathematically correct one. That said, he does it in a way that involves minimal math and only a basic understanding of logic and reason.

That's not to say the book is dumb or dumbed down. Nothing could be further from the truth. It tackles some very complex problems and some issues that have confounded mathematicians and logicians for centuries. Some of the problems don't even have an answer, and he even manages to walk you through why we've been unable to answer the question even though the answer seems obvious.

Overall, it's just a delightful book that's easy to read and leaves you much smarter than you were when you started it. There's not many books that can make such a claim.

wonderful, a joy to read
Reviewed in the United States on September 3, 2010
This is not a book of logic puzzles, but a book for people who love logic and puzzles. This is a book full of beautifully simple illuminations of some very tricky stuff. Mostly for older kids and adults. My only wish is that the graphics/layout had been done differently. The illustrations and words next to them are just too small.
