Full Description
The Gathering 4 Gardner is a biannual conference founded--and for many years organized--by Tom Rodgers to celebrate the spirit of Martin Gardner. While primarily concerned with recreational mathematics, most of Gardner's intellectual interests are featured, including magic, literature, philosophy, puzzles, art, and rationality. Gardner's writing inspired several generations of mathematicians by introducing us to the joy of discovery and exploration, and the Gathering's aim is to continue that tradition of inspiration.
This volume, a tribute to Rodgers and Gardner, consists of papers originally presented at the Gathering 4 Gardner meetings. Recreational mathematics is strongly prominent with contributions from Neil Sloane, Richard Guy, Solomon Golomb, Barry Cipra, Erik Demaine, and many others. There are games and puzzles, including new Nim-like games, chess puzzles, coin weighings, coin flippings, and contributions that combine art and puzzles or magic and puzzles. Two historical articles present the stories of combinatorial game theory and the search for God's number for Rubik's Cube. Anyone who finds pleasure in clever and intriguing intellectual puzzles will find much to enjoy in Barrycades and Septoku.
