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.

Research in mathematics is much more than solving puzzles, but most people will agree that solving puzzles is not just fun: it helps focus the mind and increases one's armory of techniques for doing mathematics. Mathematical Puzzles makes this connection explicit by isolating important mathematical methods, then using them to solve puzzles and prove a theorem. This Revised Edition has been thoroughly edited to correct errors and provide clarifications, and includes some totally different solutions, modified puzzles, and one entirely new puzzle. Features A collection of the world’s best mathematical puzzles Each chapter features a technique for solving mathematical puzzles, examples, and finally a genuine theorem of mathematics that features that technique in its proof Puzzles that are entertaining, mystifying, paradoxical, and satisfying; they are not just exercises or contest problems.

British-Israeli recreational mathematician, communicator and educator, Yossi Elran explores in-depth six of the most ingenious math puzzles, exposing their long 'tails': the stories, trivia, quirks and oddities of their history and, of course, the math and mathematicians behind them. In his unique 'talmudic', associative way, Elran shows the hidden connections between Lewis Carroll's 'Cats and Rats' puzzle and the math of taxi driving, a number pyramid magic trick and Hollywood movie fractals, and even how packing puzzles are related to COVID-19!Elran has a great talent for explaining difficult topics — including quantum mechanics, a topic he relates to some original 'operator' puzzles — making the book very accessible for all audiences.With over 40 additional, original puzzles, and touching on dozens of hot math topics, this is a perfect book for math lovers, educators, kids and adults, and anyone who loves a great read.Yossi Elran is co-author of our bestselling The Paper Puzzle Book, and heads the Innovation Center at the Davidson Institute of Science Education, the educational arm of the world-renowned Weizmann Institute of Science in Israel.
