Written originally for those elementary school teachers who knew little of common plants and animals, and even less about earth beneath their feet and the skies overhead, this book is for the most part as valid and helpful to day as it was when first written in 1911.

    The camera stops the action and magnifies it so that all the amazing states of water can be observed - water as ice, rainbow, stream, frost, dew. Readers can examine a drop of water as it falls from a faucet, see a drop of water as it splashes on a hard surface, count the points of an actual snowflake, and contemplate how drops of water form clouds.

    Each image alone exposes a nugget of our planet's magnificence; the totality of the collection goes beyond our imagination. Turning the pages, viewers are struck by the richness of life on Earth. One photograph is more awe-inspiring than the next--chosen by veteran National Geographic Magazine photo editors to present what is visually incredible. The photographs are drawn from the popular "Visions of Earth" feature in the magazine, (rated #1 by readers), from our own storied Image Collection, and from renowned photographers throughout the world, many never-before published.Enthralling images fill the book in a gallery of stunning landscapes, fascinating people, amazing animals, and unexpected glimpses of the usual and unusual. Puffins' beaks signal breeding time in Norway and a speckled emperor moth in South Africa diverts predators with an illusion. An elephant takes a morning dip in India's Andaman Sea while Siamese crocodiles race in Thailand and surfers in Australia relish a perfect day. Monks in Bhutan run to dinner and a little girl in red stands out among white-robed women in an Indonesian mosque. Spanish youth decked in colorful, oversize papier-mâché heads celebrate a festival in Catalonia and a flower of flame blooms from a man's kerosene-filled mouth in a Sikh celebration in India.Around the globe, amazing moments are captured in time, from a spray of flash frozen petal fragments in California to a truck show of chrome-covered and gleaming neon rigs half the world away in Japan. Visions of Earth is a welcome escape from the news of natural disasters, conflict, political upheaval, and social unrest that fills our lives. The book delights our senses, ignites our emotions, and renews our optimism, showcasing the many ways that our world is a marvel to behold and a privilege to call home.

    We call this imprisonment schooling, yet wonder why kids become bored and misbehave. Even outside of school children today seldom play and explore without adult supervision, and are afforded few opportunities to control their own lives. The result: anxious, unfocused children who see schooling—and life—as a series of hoops to struggle through.In Free to Learn, developmental psychologist Peter Gray argues that our children, if free to pursue their own interests through play, will not only learn all they need to know, but will do so with energy and passion. Children come into this world burning to learn, equipped with the curiosity, playfulness, and sociability to direct their own education. Yet we have squelched such instincts in a school model originally developed to indoctrinate, not to promote intellectual growth.To foster children who will thrive in today’s constantly changing world, we must entrust them to steer their own learning and development. Drawing on evidence from anthropology, psychology, and history, Gray demonstrates that free play is the primary means by which children learn to control their lives, solve problems, get along with peers, and become emotionally resilient. This capacity to learn through play evolved long ago, in hunter-gatherer bands where children acquired the skills of the culture through their own initiatives. And these instincts still operate remarkably well today, as studies at alternative, democratically administered schools show. When children are in charge of their own education, they learn better—and at lower cost than the traditional model of coercive schooling.A brave, counterintuitive proposal for freeing our children from the shackles of the curiosity-killing institution we call school, Free to Learn suggests that it’s time to stop asking what’s wrong with our children, and start asking what’s wrong with the system. It shows how we can act—both as parents and as members of society—to improve children’s lives and promote their happiness and learning.

    We spin fantasies. We devour novels, films, and plays. Even sporting events and criminal trials unfold as narratives. Yet the world of story has long remained an undiscovered and unmapped country. It’s easy to say that humans are “wired” for story, but why?In this delightful and original book, Jonathan Gottschall offers the first unified theory of storytelling. He argues that stories help us navigate life’s complex social problems—just as flight simulators prepare pilots for difficult situations. Storytelling has evolved, like other behaviors, to ensure our survival.Drawing on the latest research in neuroscience, psychology, and evolutionary biology, Gottschall tells us what it means to be a storytelling animal. Did you know that the more absorbed you are in a story, the more it changes your behavior? That all children act out the same kinds of stories, whether they grow up in a slum or a suburb? That people who read more fiction are more empathetic?Of course, our story instinct has a darker side. It makes us vulnerable to conspiracy theories, advertisements, and narratives about ourselves that are more “truthy” than true. National myths can also be terribly dangerous: Hitler’s ambitions were partly fueled by a story.But as Gottschall shows in this remarkable book, stories can also change the world for the better. Most successful stories are moral—they teach us how to live, whether explicitly or implicitly, and bind us together around common values. We know we are master shapers of story. The Storytelling Animal finally reveals how stories shape us.

    How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

    Once again, the Bird and Bee are up to their antics, but this time they're younger.

    This book is intended for use in a one- or two-semester course in environmental science, human ecology, or environmental studies at the college or advanced placement high school level.The goal of this book is to provide an up-to-date, introductory global view of essential themes in environmental science along with emphasis on details and case studies that will help students process and retain the general principles. Because most students who will use this book are freshman or sophomore non-science majors, the authors make the text readable and accessible without technical jargon or a presumption of prior science background. At the same time, enough data and depth are presented to make this book suitable for many upper-division classes and a valuable resource for students who will keep it in their personal libraries after their formal studies are completed.
