As he did so masterfully in Prime Obsession, Derbyshire brings the evolution of mathematical thinking to dramatic life by focusing on the key historical players. Unknown Quantity begins in the time of Abraham and Isaac and moves from Abel's proof to the higher levels of abstraction developed by Galois through modern-day advances. Derbyshire explains how a simple turn of thought from this plus this equals this to this plus what equals this? gave birth to a whole new way of perceiving the world. With a historian's narrative authority and a beloved teacher's clarity and passion, Derbyshire leads readers on an intellectually satisfying and pleasantly challenging historical and mathematical journey.

    

    In this lively book of essays, Stephen Wolfram takes the reader along on some of his most surprising and engaging intellectual adventures in science, technology, artificial intelligence and language design.

    The mathematician, born on June 23, 1912, was a brilliant World War II codebreaker and parlayed that insight into theorizing and creating the first stored-memory computers. Unfortunately, this Officer of the British Empire was persecuted by the British government of the time for his homosexuality and suffered through chemical castration before ending his life.The Imitation Game by Feynman author Jim Ottaviani and Resistance illustrator Leland Purvis chronicles the life of Turing in a full-size graphic novel.

    The work is predicated on the idea that studying mathematics can generate the same enthusiasm as playing a team sport - without necessarily being competitive.

    In No More Teaching a Letter a Week, early literacy researcher Dr. William Teale helps us understand that alphabet knowledge is more than letter recognition, and identifies research-based principles of effective alphabet instruction, which constitutes the foundation for phonics teaching and learning. Literacy coach Rebecca McKay shows us how to bring those principles to life through purposeful practices that invite children to create an identity through print.Children can and should do more than glue beans into the shape of a B; they need to learn how letters create words that carry meaning, so that they can, and do, use print to expand their understanding of the world and themselves.

    In this collection of landmark mathematical works, editor Stephen Hawking has assembled the greatest feats humans have ever accomplished using just numbers and their brains.

    It is through developing a self-reliant mindset, having essential survival gear and a handful of critical skills, that you and your family will be able to prevail in an urban crisis. Jammed with field-tested information from real-world applications, survival instructor Tony Nester covers how to prepare for both short-term survival ranging from 24-72 hours as well as long-term situations resulting from a grid-down emergency or pandemic. When the Grid Goes Down will show you how to make your home and lifestyle more self-sufficient and the critical gear needed along the way. Topics include: The 6 Key Areas for Creating a Self-Reliant Home, Water Storage and Purification Methods, Alternative Water Sources At Home, Creating a Water Map for Your Region, The 3 Essential Food Types to Stock Up On, Designing an Off-Grid Medical Kit, Home Security and Personal Defense Measures, Safeguarding the Exterior and Interior of Your Home, Heating, Cooling and Lighting When the Power Goes Out, and Alternative Sanitation and Hygiene Methods.

    It demonstrates how to encourage, develop, and foster the processes which seem to come naturally to mathematicians.

     You'll love seeing Kim and a fellow ranger tested as they bravely take on the task of relocating 77 live skunks by sedating them with darts from homemade blowguns, especially when the pickup truck load of stinkers wakes up while still in transit. An hilarious, heartwarming, and heartbreaking memoir by the chief wildlife ranger in the #1 most popular family vacation destination in the USA, the Great Smoky Mountains National Park. For over thirty years, Kim DeLozier acted as a referee in the wild, trying to protect millions of park visitors from one of the densest populations of wild black bears in America -- and the bears from tourists who get too close. Written with bestselling author Carolyn Jourdan who has several highly-regarded #1 Amazon bestsellers about the Smoky Mountains.

    The discussion of problem solving strategies is extensive. It is written for trainers and participants of contests of all levels up to the highest level: IMO, Tournament of the Towns, and the noncalculus parts of the Putnam Competition. It will appeal to high school teachers conducting a mathematics club who need a range of simple to complex problems and to those instructors wishing to pose a "problem of the week", "problem of the month", and "research problem of the year" to their students, thus bringing a creative atmosphere into their classrooms with continuous discussions of mathematical problems. This volume is a must-have for instructors wishing to enrich their teaching with some interesting non-routine problems and for individuals who are just interested in solving difficult and challenging problems. Each chapter starts with typical examples illustrating the central concepts and is followed by a number of carefully selected problems and their solutions. Most of the solutions are complete, but some merely point to the road leading to the final solution. Very few problems have no solutions. Readers interested in increasing the effectiveness of the book can do so by working on the examples in addition to the problems thereby increasing the number of problems to over 1300. In addition to being a valuable resource of mathematical problems and solution strategies, this volume is the most complete training book on the market.

    Containing information necessary for teachers to teach math through problem solving, this resource is filled with engaging activities from every strand of mathematics.
