Taken literally, it implies that there are many universes “parallel” to the one we see around us. This multiplicity of universes, according to Deutsch, turns out to be the key to achieving a new worldview, one which synthesizes the theories of evolution, computation, and knowledge with quantum physics. Considered jointly, these four strands of explanation reveal a unified fabric of reality that is both objective and comprehensible, the subject of this daring, challenging book. The Fabric of Reality explains and connects many topics at the leading edge of current research and thinking, such as quantum computers (which work by effectively collaborating with their counterparts in other universes), the physics of time travel, the comprehensibility of nature and the physical limits of virtual reality, the significance of human life, and the ultimate fate of the universe. Here, for scientist and layperson alike, for philosopher, science-fiction reader, biologist, and computer expert, is a startlingly complete and rational synthesis of disciplines, and a new, optimistic message about existence.

    It was a wall that kept growing and growing. But its construction came at a huge cost: it is believed that more than a million Chinese died building it, earning the wall its nickname--the longest cemetery on earth. Through the story of the wall, Patricia Brennan Demuth is able to tell the story of China itself, the rise and fall of dynasties, the greatness of its culture, and its present-day status as a Communist world power.

    If the idea of a computer science book without computers upsets you, please close your eyes until you’ve finished reading the rest of this page.The truth is that computer science is not really about the computer. It is just a tool to help you see ideas more clearly. You can see the moon and stars without a telescope, smell the flowers without a fluoroscope, have fun without a funoscope, and be silly sans oscilloscope.You can also play with computer science without... you-know-what. Ideas are the real stuff of computer science. This book is about those ideas, and how to find them.

No boyhood is complete without a copy!The Big Book of Boy Stuff has all the important information that boys just have to know: How can I make a rocket? What do I do if I get a bean stuck up my nose? How can I make lightning without killing myself? Where can I find new practical jokes? What is the best way to poop outside? How do I tell a girl I like her? Why would I tell a girl I like her? How many mosquitoes does it take to suck all the blood out of a person? What's that smell? . . . and many, many more!The veteran of many water-balloon wars, Bart King has twice won the prized "Arrested Development" award from the New York Society of Amateur Psychologists. He has been a middle-school teacher for the past fifteen years. This is his first book, unless you count that other one he wrote. Bart has interviewed hundreds of the country's wisest guys and smartest alecks for the incredible material in The Big Book of Boy Stuff.Bart invites you to visit this book's website at: www.bartking.net

    The volume includes over forty of the Grimms' most beloved stories, including:Rapunzel * Hansel and Gretel * The Brave Little Tailor * Cinderella * Little Red Riding Hood * The Robber Bridegroom * Briar Rose * Snow White * Rumplestilskin * The Golden Goose * The Singing, Soaring Lark * The Frog King * The Juniper Tree * and Mother HolleWith over 150 paintings and drawings from the most celebrated fairy tale illustrators, including George Cruikshank, Paul Hey, Walter Crane, Warwick Goble, Kay Nielsen, and Arthur Rackham.

    He explores what parents, teachers, and employers must do to develop the capacities of young people to become innovators. In profiling compelling young American innovators such as Kirk Phelps, product manager for Apple’s first iPhone, and Jodie Wu, who founded a company that builds bicycle-powered maize shellers in Tanzania, Wagner reveals how the adults in their lives nurtured their creativity and sparked their imaginations, while teaching them to learn from failures and persevere. Wagner identifies a pattern—a childhood of creative play leads to deep-seated interests, which in adolescence and adulthood blossom into a deeper purpose for career and life goals. Play, passion, and purpose: These are the forces that drive young innovators. Wagner shows how we can apply this knowledge as educators and what parents can do to compensate for poor schooling. He takes readers into the most forward-thinking schools, colleges, and workplaces in the country, where teachers and employers are developing cultures of innovation based on collaboration, interdisciplinary problem-solving, and intrinsic motivation. The result is a timely, provocative, and inspiring manifesto that will change how we look at our schools and workplaces, and provide us with a road map for creating the change makers of tomorrow. Creating Innovators will feature its own innovative elements: more than sixty original videos that expand on key ideas in the book through interviews with young innovators, teachers, writers, CEOs, and entrepreneurs, including Thomas Friedman, Dean Kamen, and Annmarie Neal. Produced by filmmaker Robert A. Compton, the videos are embedded into the ebook edition in video-enabled eReaders and accessible in this print edition via QR codes placed throughout the chapters or via www.creatinginnovators.com.

He attends the World Mathematical Congress in India, and visits the engineer who designed the first roller-coaster loop. Get hooked on math as Alex delves deep into humankind’s turbulent relationship with numbers, and reveals how they have shaped the world we live in.

    As we dream with him, we are taken further and further into mathematical theory, where ideas eventually take flight, until everyone--from those who fumble over fractions to those who solve complex equations in their heads--winds up marveling at what numbers can do.Hans Magnus Enzensberger is a true polymath, the kind of superb intellectual who loves thinking and marshals all of his charm and wit to share his passions with the world. In The Number Devil, he brings together the surreal logic of Alice in Wonderland and the existential geometry of Flatland with the kind of math everyone would love, if only they had a number devil to teach them.

    He was such a daydreamer that people called him a blockhead.When Leonardo grew up and traveled the world, he was inspired by the numbers used in different countries. Then he realized that many things in nature, from the number of petals on a flower to the spiral of a nautilus shell, seem to follow a certain pattern. The boy who was once teased for being a blockhead had discovered what came to be known as the Fibonacci Sequence!
