Presents a collection of visual challenges, riddles, and puzzles.
About the original 1000 PlayThinks,Will Shortz of The New York Times said it best: “The most wide-ranging, visually appealing, entertaining, gigantic collection of brainteasers since Sam Loyd’s Cyclopedia of Puzzles almost a century ago.” Inside The Big Book of Brain Games, you will find an obsessive collection of 1,000 challenges, puzzles, riddles, illusions—originals as well as must-do classics—it’s like salted peanuts for the brain. With jampacked pages and a full-color illustration for each entry, the book, opened anywhere, is a call to action. (And it’s guaranteed to make you smarter.) Twelve basic categories include Geometry, Patterns, Numbers, Logic and Probability, and Perception. An easy-to-read key at the top of each game ranks its difficulty on a scale of 1 to 10, while indices in the back cross-reference the puzzles. (You’ll find the answers back there, too.)
Colorful geometrical pentagors, composed of pentagons and triangles and dissected into pieces: Can you put the shapes together again to form a whole? A classic paradox about the nature of motion from a famous Greek mathematician: Can you see what’s wrong with it? Put on your thinking cap and prepare to give your math and logic abilities a workout, because these super-looking puzzles demand real brainpower. Solve a graphic problem that involves the calculation of a square root. Examine six linear processions of egg-carrying ants, and figure out which lines are “surprising” and which ones aren’t. Go step by step through a multihued grid and try to find 32 different configurations within. These puzzles are challenging, entertaining, and satisfying to unravel.
Treasury of 300 puzzles features 3D and chess puzzles, connections, dissections, foldings, geometrical and number puzzles, logic problems, matchstick puzzles, mazes, moving pieces, put-togethers, strimkos, sudoku, and visual and word puzzles.
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.
A collection of math and logic puzzles features number games, magic squares, tricks, problems with dominoes and dice, and cross sums, in addition to other intellectual teasers.
'The whizz-kid making maths supercool. . . A brilliant book that takes everything we know (and fear) about maths out of the equation - starting with numbers' The Times 'A cheerful, chatty, and charming trip through the world of mathematics. . . Everyone should read this delightful book' Ian Stewart, author of Do Dice Play God? The only numbers in this book are the page numbers. The three main branches of abstract math - topology, analysis, and algebra - turn out to be surprisingly easy to grasp. Or at least, they are when our guide is a math prodigy. With forthright wit and warm charm, Milo Beckman upends the conventional approach to mathematics, inviting us to think creatively about shape and dimension, the infinite and the infinitesimal, symmetries, proofs, and all how all these concepts fit together. Why is there a million dollar prize for counting shapes? Is anything bigger than infinity? And how is the 'truth' of mathematics actually decided? A vivid and wholly original guide to the math that makes the world tick and the planets revolve, Math Without Numbers makes human and understandable the elevated and hypothetical, allowing us to clearly see abstract math for what it is: bizarre, beautiful, and head-scratchingly wonderful.
"A renowned puzzle master and game inventor presents 315 new and traditional puzzles. The Puzzle Universe is intended for general readers and devoted puzzlers. It is about the latent beauty of mathematics, its history, and the puzzles that have advanced and emerged from the science of numbers. It is full of challenging historical facts, thinking puzzles, paradoxes, illusions, and problem solving. There are 315 puzzles in this book. Extended captions explain in easy terms the value of the puzzles for mathematical and educational purposes, particularly in light of the findings of recent research. This historical and pedagogical dimension sets The Puzzle Universe apart from similar books. The puzzles appear in a dynamic layout for a visual experience that is Ivan Moscovich's trademark. There are ten chapters complete with answers. Icons show the challenge rating and the tools needed (pencil, scissors, ruler, and of course, brain) to solve the puzzle."--
Virtually a modern fitness studio for the brain, 150 diverse puzzles help to keep minds flexible and to boost mental stamina in logical and mathematical thinking. The challenges posed by this new training program are a fun way of finding a logical path through the puzzle labyrinth.
Algorithmic puzzles are puzzles involving well-defined procedures for solving problems. This book will provide an enjoyable and accessible introduction to algorithmic puzzles that will develop the reader's algorithmic thinking. The first part of this book is a tutorial on algorithm design strategies and analysis techniques. Algorithm design strategies — exhaustive search, backtracking, divide-and-conquer and a few others — are general approaches to designing step-by-step instructions for solving problems. Analysis techniques are methods for investigating such procedures to answer questions about the ultimate result of the procedure or how many steps are executed before the procedure stops. The discussion is an elementary level, with puzzle examples, and requires neither programming nor mathematics beyond a secondary school level. Thus, the tutorial provides a gentle and entertaining introduction to main ideas in high-level algorithmic problem solving. The second and main part of the book contains 150 puzzles, from centuries-old classics to newcomers often asked during job interviews at computing, engineering, and financial companies. The puzzles are divided into three groups by their difficulty levels. The first fifty puzzles in the Easier Puzzles section require only middle school mathematics. The sixty puzzle of average difficulty and forty harder puzzles require just high school mathematics plus a few topics such as binary numbers and simple recurrences, which are reviewed in the tutorial. All the puzzles are provided with hints, detailed solutions, and brief comments. The comments deal with the puzzle origins and design or analysis techniques used in the solution. The book should be of interest to puzzle lovers, students and teachers of algorithm courses, and persons expecting to be given puzzles during job interviews.
