Book Description
A colorful square, dissected into four parts, with hinges marked in black. If you leave the blue piece fixed and swing the others around their hinges, a new shape will emerge. Can you guess just by looking what it will be? This is just one of the tricky geometrical gems that will make a puzzler’s mind work overtime. Try drawing a set of variously shaped polygons using only a compass and a ruler (no measuring allowed!), figuring out which of two sculptures is bigger (logic alone won’t give you the answer), and lots more.

Book Description
Calculate velocity; explain the Maltese cross mechanism that's the basis of the motion picture projector; and work out the ways different pendulums (including Foucault's famous version) swing. Every attractive page in master Ivan Moscovich's eleventh collection of brain-busters offers a tricky puzzle pleasure. Sixteen tiles show either a crowned frog or a crown prince: distribute them randomly on a game board, face down, and then see if you can come up with a configuration that will allow you to flip them so that all frogs or all princes will turn up. Discern the logic of a number pattern in a partially filled-out grid and discover the missing numerals. From gnomic expansions to infinity and limit, these dilemmas demand a smart solver.

Book Description
A dissection involves cutting a polygon into pieces in such a way that those pieces form another polygon; for a hinged dissection, the pieces must be attached by hinges. A piano hinge is "a long narrow hinge with a pin running the entire length of its joint." So, unlike regular hinged dissections, which swing or twist (around single point of hinge)

Book Description
Puzzlers will feel fit to be tied - Dog Tied: If Fido is tied to a 10-foot-long rope, and his bone is 15 feet away, how is it possible that he can reach and enjoy his bone without breaking or stretching the rope? (And yes - the rope IS tied to something.) There's fun in finding the answer to this and other cool number-based problems. Dust off your mathematics and get solving. The intriguing enigmas include questions on interstellar communications, ancient geometry (Pythagoras and Plato), and even traffic patterns in gridlock city. Or play the grasshopper jumping game. It's all fascinating.

Book Description
Martin Gardner's Mathematical Games columns in Scientific American inspired and entertained several generations of mathematicians and scientists. Gardner in his crystal-clear prose illuminated corners of mathematics, especially recreational mathematics, that most people had no idea existed. His playful spirit and inquisitive nature invite the reader into an exploration of beautiful mathematical ideas along with him. These columns were both a revelation and a gift when he wrote them; no one--before Gardner--had written about mathematics like this. They continue to be a marvel. This volume, originally published in 1959, contains the first sixteen columns published in the magazine from 1956-1958. They were reviewed and briefly updated by Gardner for this 1988 edition.
