The Shoelace Problem & Other Puzzles
Sterling Publishing Company, Inc., 2004 - Всего страниц: 128
Problem solving is a pleasure—when you can get rid of those mental blocks. That’s just what this collection of puzzles helps you do, even as it offers hours of entertainment. There’s advice on working through the tough spots and exercising those creative mental muscles. Start with a classic about The Man with No Eyes. He’s gone to the woods to view the skies. He sees a tree with apples on it: he takes none off, yet leaves none on. How can this be? Or try the numerical St. Ives Riddle, from a rhyme first published in 1202. Decipher mystery signs, make Symmetry Folds, and do the Twenty-Five Point Connect.
