Jacobs—four-time New York Times bestselling author, master of immersion journalism, and nightly crossworder—set out to determine their myriad benefits. And maybe, in the process, solve the puzzle of our very existence. Well, almost. In The Puzzler, Jacobs meets the most zealous devotees, enters (sometimes with his family in tow) any puzzle competition that will have him, unpacks the history of the most popular puzzles, and aims to solve the most impossible head-scratchers, from a mutant Rubik’s Cube, to the hardest corn maze in America, to the most sadistic jigsaw. Chock-full of unforgettable adventures and original examples from around the world—including new work by Greg Pliska, one of America’s top puzzle-makers, and a hidden, super-challenging but solvable puzzle—The Puzzler will open readers’ eyes to the power of flexible thinking and concentration. Whether you’re puzzle obsessed or puzzle hesitant, you’ll walk away with real problem-solving strategies and pathways toward becoming a better thinker and decision maker—for these are certainly puzzling times.

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.

A human-centric guide to solving complex problems in engineering management, from sizing teams to handling technical debt. There’s a saying that people don’t leave companies, they leave managers. Management is a key part of any organization, yet the discipline is often self-taught and unstructured.

Will Larson’s An Elegant Puzzle focuses on the particular challenges of engineering management—from sizing teams to handling technical debt to performing succession planning—and provides a path to the good solutions. Drawing from his experience at Digg, Uber, and Stripe, Larson has developed a thoughtful approach to engineering management for leaders of all levels at companies of all sizes. An Elegant Puzzle balances structured principles and human-centric thinking to help any leader create more effective and rewarding organizations for engineers to thrive in.

Most chess puzzle books put you in an artificial situation: you are told a combination exists, what the theme is and what you are required to achieve. This one is different. In a real game, a player may sometimes need to find a combination. On the other hand he may have to reject a tactical idea and simply find a good positional move. His task is to find the right move, whatever it may be. The 300 puzzles in this book put you precisely in that situation. Spectacular ideas abound in these positions, but it is for you to decide whether to go in for them, or whether you would be falling into a trap. If you need them, there are hints to help you on your way. The book ends with a series of tests to measure your skills against those of other players. For this new edition, John Nunn, a top-class grandmaster and a solving world champion, has added 50 new puzzles (with hints and detailed solutions) to test your skills to the full. For ease of following, extra diagrams have been added to the solutions throughout. Overall the book is 60 per cent bigger than the first edition.
