This is a collection of intriguing mathematical problems and activities arising from our everyday experience.

"Science experiments for kids that solve problems"--

Examples help explain the seven basic mathematical problem-solving methods, including inference, classification of action sequences, working backward, and contradiction

From Ashima Shiraishi, one of the world's youngest and most skilled climbers, comes a true story of strength and perseverance--in rock climbing and in life. To a rock climber, a boulder is called a "problem," and you solve it by climbing to the top. There are twists and turns, falls and scrapes, and obstacles that seem insurmountable until you learn to see the possibilities within them. And then there is the moment of triumph, when there's nothing above you but sky and nothing below but a goal achieved. Ashima Shiraishi draws on her experience as a world-class climber in this story that challenges readers to tackle the problems in their own lives and rise to greater heights than they would have ever thought possible.

The bestselling book that has helped millions of readers solve any problem A must-have guide by eminent mathematician G. Polya, How to Solve It shows anyone in any field how to think straight. In lucid and appealing prose, Polya reveals how the mathematical method of demonstrating a proof or finding an unknown can help you attack any problem that can be reasoned out—from building a bridge to winning a game of anagrams. How to Solve It includes a heuristic dictionary with dozens of entries on how to make problems more manageable—from analogy and induction to the heuristic method of starting with a goal and working backward to something you already know. This disarmingly elementary book explains how to harness curiosity in the classroom, bring the inventive faculties of students into play, and experience the triumph of discovery. But it’s not just for the classroom. Generations of readers from all walks of life have relished Polya’s brilliantly deft instructions on stripping away irrelevancies and going straight to the heart of a problem.

No pleasure lasts long unless there is variety in it. Publilius Syrus, Moral Sayings We've been very fortunate to receive fantastic feedback from our readers during the last four years, since the first edition of How to Solve It: Modern Heuristics was published in 1999. It's heartening to know that so many people appreciated the book and, even more importantly, were using the book to help them solve their problems. One professor, who published a review of the book, said that his students had given the best course reviews he'd seen in 15 years when using our text. There can be hardly any better praise, except to add that one of the book reviews published in a SIAM journal received the best review award as well. We greatly appreciate your kind words and personal comments that you sent, including the few cases where you found some typographical or other errors. Thank you all for this wonderful support.

Seven problem-solving techniques include inference, classification of action sequences, subgoals, contradiction, working backward, relations between problems, and mathematical representation. Also, problems from mathematics, science, and engineering with complete solutions.

A high-class puzzle book from the bestselling author of Alex's Adventures in Numberland; organised from easy-peasy to ninja level - with stories of puzzle mysteries, histories and scandals along the way this book will make your hippocampus happy.

In survey after survey, executives list attracting and retaining top talent as their #1 issue. Is it your top concern? While the people puzzle isn’t easy to solve, this book features compelling research, specific personal and client stories, and key perspectives from top business leaders and experts―all in a format that’s easy to read and prompts readers to act. Kathleen Quinn Votaw has years of experience working with CEOs who understand that traditional staffing methods don’t work for today’s companies, and in this book she offers advice on how to: keep “A Players” engaged, boosting retention and reducing turnover; attract people who will thrive in a demanding, uncertain, entrepreneurial environment; and Always Be Cultivating (ABC) by thinking of recruitment as a sales process.

One of "The Most Fascinating Books WIRED Read in 2020" "One part science book, one part historical narrative, one part memoir . . . harrowing and inspiring.”—The Wall Street Journal How a determined scientist cracked the case of the first successful—and disastrous—submarine attack On the night of February 17, 1864, the tiny Confederate submarine HL Hunley made its way toward the USS Housatonic just outside Charleston harbor. Within a matter of hours, the Union ship’s stern was blown open in a spray of wood planks. The explosion sank the ship, killing many of its crew. And the submarine, the first ever to be successful in combat, disappeared without a trace. For 131 years the eight-man crew of the HL Hunley lay in their watery graves, undiscovered. When finally raised, the narrow metal vessel revealed a puzzling sight. There was no indication the blast had breached the hull, and all eight men were still seated at their stations—frozen in time after more than a century. Why did it sink? Why did the men die? Archaeologists and conservationists have been studying the boat and the remains for years, and now one woman has the answers. In the Waves is much more than just a military perspective or a technical account. It’s also the story of Rachel Lance’s single-minded obsession spanning three years, the story of the extreme highs and lows in her quest to find all the puzzle pieces of the Hunley. Balancing a gripping historical tale and original research with a personal story of professional and private obstacles, In the Waves is an enthralling look at a unique part of the Civil War and the lengths one scientist will go to uncover its secrets.
