ادای احترام به یک معماگر رنگارنگ

The tradition of honoring Martin Gardner continues with this edited collection of articles by those who have been inspired by Gardner to enter mathematics, to enter magic, to bring magic into their mathematics, or to bring mathematics into their magic. Contributing authors include world-leading puzzle designers, puzzle collectors, mathematicians, and magicians. The variety of articles includes card or magic tricks (with a mathematical trick behind them), the history behind given puzzles, mathematically interesting objects involving the number seven, and puzzles for the reader to solve. Specific puzzles discussed include tangram, 14-15 Puzzle, seven-coloring of the torus, packing circles, Crazy Elephant Dance, and more!

The articles collected in this volume are as varied as Gardner's interests, including care or magic tricks (with a mathematical trick behind them), the history behind given puzzles, mathematically interesting objects, and puzzles for the reader to solve."--Jacket
