The Hinged Square & Other Puzzles by Ivan Moscovich Pdf

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.

Loopy Logic Problems and Other Puzzles by Ivan Moscovich Pdf

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.

Games, Puzzles, and Computation by Robert A. Hearn,Erik D. Demaine Pdf

The authors show that there are underlying mathematical reasons for why games and puzzles are challenging (and perhaps why they are so much fun). They also show that games and puzzles can serve as powerful models of computation-quite different from the usual models of automata and circuits-offering a new way of thinking about computation.

Genius Gymnasium by Ivan Moscovich Pdf

It takes physical exercise to build the body—and it takes a workout to strengthen the brain, too. Ivan Moscovich is a masterful coach, and he’s created a selection of tricky conundrums to enhance every muscle of the mind. Because each puzzle must be completed in just one minute, there’s a little hourglass timer (built into the book’s front cover) that’s custom-made to run for 60 seconds. Set it, and start the “circuit training” with the creative thinking puzzles: These graded problems develop flexibility, lasting mental stamina, and all-around mental fitness. Plus, they refine solvers’ natural aptitude for the logic, number, visual reasoning, and word puzzles that follow. The culmination: a special Genius Gymnasium program that helps maintain the brain for years to come!

Cunning Combination Problems & Other Puzzles by Ivan Moscovich Pdf

There's magic in these brainteasers. Most of them play variations on the magic square, among the oldest puzzles that exist. These cubes or other shapes are made up of groups of cells, each cell containing one of a set of numbers. The set generally corresponds with the number of cells, so, for example, a five-by-five magic square would contain numbers from 1 to 25. The trick: the sum of the numbers in any one row or column (and sometimes diagonal) must be the same. It's pure mathematical beauty. Examine and attempt to figure out the workings of a "diabolic" version created by D�rer, an early variation by Lo-Shu, and variants that use colors, different shapes, and hinged tiles.

Piano-Hinged Dissections by Greg N. Frederickson Pdf

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)
