Some of you may be interested in the following web posting which I found useful. It is a web page posted by Professor Carl W. Lee of the University of Kentucky. It is an index to fifteen of the Martin Gardner books that contain collections of his articles from Scientific American.

The web site is:

(I'm new to this, I hope the link works. If not, you may have to cut and paste it into your browser address line.)

I found this site via a web search after an exchange on the Book Review topic re Ahead of the Pack. Reference was made there to a nontransitive game/proposition bet. With the index I was able to fairly quickly find Gardner's chapter on nontransitive paradoxes in the book Time Travel and Other Mathematical Bewilderments.

Lots of entries on magic tricks, magic squares, games, puzzles, paradoxes, etc.

Hope some of you find this useful.

Gardner's books are amazing, lots of interesting math for the amateur and pro as well.
There’s also a lot of magic inside too.

I have just ordered the 15 books on CD from Amazon.com
