Martin Gardner’s “Mathematical Games” column ran in *Scientific American* from 1956 to 1986. In these columns Gardner introduced hundreds of thousands of readers to the delights of mathematics and of puzzles and problem solving. His column broke such stories as Rivest, Shamir, and Adelman on public-key cryptography, Mandelbrot on fractals, Conway on Life, and Penrose on tilings. He enlivened classic geometry and number theory and introduced readers to new areas such as combinatorics and graph theory. Now this material has been brought together on a single, searchable source. A profile/interview of Martin Gardner with dozens of photos is included on the CD.

### About the Author

For 25 of his 94 years, **Martin Gardner** wrote “Mathematical Games and Recreations,” a monthly column for* Scientific American* magazine. These columns have inspired hundreds of thousands of readers to delve more deeply into the large world of mathematics. He has also made significant contributions to magic, philosophy, children’s literature, and the debunking of pseudoscience. He has produced more than 60 books, including many best sellers, most of which are still in print. His *Annotated Alice* has sold more than one million copies.
