More than two hundred new and challenging logic puzzles—the simplest brainteaser to the most complex paradoxes in contemporary mathematical thinking—from our topmost puzzlemaster (“the most entertaining logician who ever lived,” Martin Gardner has called him). Our guide to the puzzles is the Sorcerer, who resides on the Island of Knights and Knaves, where knights always tell the truth and knaves always lie, and he introduces us to the amazing magic—logic—that enables to discover which inhabitants are which. Then, in a picaresque adventure in logic, he takes us to the planet Og, to the Island of Partial Silence, and to a land where metallic robots wearing strings of capital letters are noisily duplicating and dismantling themselves and others. The reader’s job is to figure out how it all works. Finally, we accompany the Sorcerer on an alluring tour of Infinity which includes George Cantor’s amazing mathematical insights. The tour (and the book) ends with Satan devising a diabolical puzzle for one of Cantor’s prize students—who outwits him! In sum: a devilish magician’s cornucopia of puzzles—a delight for every age and level of ability.

Noted Japanese papercraft designer Haruki Nakamura created this wonderful collection of interlocking puzzles to intrigue and delight papercraft, puzzle and geometry enthusiasts alike. These endlessly entertaining paper puzzles are impossible to put down. They include the following models: Dodecahedron Bears and Frogs--cute animal "couples" that form a 12-faced geodesic sphere when fitted together. Bird and Fish modules that dovetail together to create a seamless 3D form in a nod to Escher's Sky and Water woodcut. With the addition of some small craft magnets to its joined irregular octahedrons, a Reversible Dodecahedron that dramatically inverts itself when tossed into the air! An intricate Pyramid Box that conceals a secret inner chamber that is perfect for presenting a small gift to that special someone. The challenging 4-Piece Tetrahedron and 12-Lizard Cube provide a tremendous feeling of satisfaction once all of the pieces finally align into place. Plus many more! The step-by-step instructions are very easy to follow and show you how to assemble the individual paper components, then how to put them together to create the larger interlocking models. The template of each piece is available to print, so get out some cardstock and your X-Acto knife and start cutting! Then simply bend or fold where indicated, and bind together with a little glue. Each project is a new challenge, and the finished objects are great conversation pieces that look fantastic on your desk or shelf!
