Pearls from the Martin Gardner oyster farm

There is nothing like a good paradox to sharpen the wits. Properly presented, they can frustrate you to the point of grinding off the sharp points of your teeth. The title selection from this collection of Martin Gardners' Mathematical Recreations columns from Scientific American is one of the better paradoxes that you will find. The solution is surprisingly easy, once the proper approach is taken. The other entries are also vintage Gardner, who has no equal in the accurate rendition of mathematical curiosa. Other topics include gambling fallacies, a church of the fourth dimension, games and systems that learn by experience. There are also thirty-seven catch questions in a final chapter that are definitely groaners. Upon initial reading, the answer appears easy. However, the careful and precise wording of the problem often leads to an unusual but correct solution. If you have a curiosity driven desire to learn mathematics, then Martin Gardner is an excellent place to begin or continue your exploration. Even though the articles collected here were written in the early sixties, the topics are timeless and will continue to intrigue new generations of the mathematically inclined.

Curiosities of math/logic, and more

I read this book in the early '70s, and it remains one of my favorites. You don't need to know much math to enjoy this collection of curiosities that are mostly math- or logic-related. The text is a combination of puzzles, instructive prose, and stories. The book is easy-to-read and informative, with many references for additional reading.Mr. Gardner writes about: a drill bit for drilling square holes; different types of spiral curves; social behavior of the inhabitants of two-dimensional worlds; bar tricks; geometric dissections of polygons; peg solitaire games; the transcendental number "e"; cartoons that are read both right side up and upside down; game-playing machines; and more.
