    But our fears are misplaced, according to Yale early childhood expert Erika Christakis. Children are powerful and inventive; and the tools to reimagine their learning environment are right in front of our eyes.           Children are hardwired to learn in any setting, but they don’t get the support they need when “learning” is defined by strict lessons and dodgy metrics that devalue children’s intelligence while placing unfit requirements on their developing brains. We have confused schooling with learning, and we have altered the very habitat young children occupy. The race for successful outcomes has blinded us to how young children actually process the world, acquire skills, and grow, says Christakis, who powerfully defends the preschool years as a life stage of inherent value and not merely as preparation for a demanding or uncertain future.           In her pathbreaking book, Christakis explores what it’s like to be a young child in America today, in a world designed by and for adults. With school-testing mandates run amok, playfulness squeezed, and young children increasingly pathologized for old-fashioned behaviors like daydreaming and clumsiness, it’s easy to miss what’s important about the crucial years of three to six, and the kind of guidance preschoolers really need. Christakis provides a forensic and far-reaching analysis of today’s whole system of early learning, exploring pedagogy, history, science, policy, and politics. She also offers a wealth of proven strategies about what to do to reimagine the learning environment to suit the child’s real, but often invisible, needs. The ideas range from accommodating children’s sense of time, to decluttering classrooms, to learning how to better observe and listen as children express themselves in pictures and words.           With her strong foundation in the study of child development and early education and her own in-the-trenches classroom experience, Christakis peels back the mystery of early childhood, revealing a place that’s rich with possibility. Her message is energizing and reassuring: Parents have more power (and more knowledge) than they think they do, and young children are inherently creative and will flourish, if we can learn new ways to support them and restore their vital learning habitat.

    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.

    Or the blissful abandon of a golden retriever racing with glee across a lawn. This is the joy of play. By definition, play is purposeless and all-consuming. And, most important, it’s fun. As we become adults, taking time to play feels like a guilty pleasure—a distraction from “real” work and life. But as Dr. Stuart Brown illustrates, play is anything but trivial. It is a biological drive as integral to our health as sleep or nutrition. In fact, our ability to play throughout life is the single most important factor in determining our success and happiness. Dr. Brown has spent his career studying animal behavior and conducting more than six thousand “play histories” of humans from all walks of life—from serial murderers to Nobel Prize winners. Backed by the latest research, Play explains why play is essential to our social skills, adaptability, intelligence, creativity, ability to problem solve, and more. Play is hardwired into our brains—it is the mechanism by which we become resilient, smart, and adaptable people. Beyond play’s role in our personal fulfillment, its benefits have profound implications for child development and the way we parent, education and social policy, business innovation, productivity, and even the future of our society. From new research suggesting the direct role of three-dimensional-object play in shaping our brains to animal studies showing the startling effects of the lack of play, Brown provides a sweeping look at the latest breakthroughs in our understanding of the importance of this behavior. A fascinating blend of cutting-edge neuroscience, biology, psychology, social science, and inspiring human stories of the transformative power of play, this book proves why play just might be the most important work we can ever do.

    Back then, most experts believed that differences in how girls and boys behave are mainly due to differences in how they were treated by their parents, teachers, and friends.It's hard to cling to that belief today. An avalanche of research over the past twenty years has shown that sex differences are more significant and profound than anybody guessed. Sex differences are real, biologically programmed, and important to how children are raised, disciplined, and educated. In Why Gender Matters, psychologist and family physician Dr. Leonard Sax leads parents through the mystifying world of gender differences by explaining the biologically different ways in which children think, feel, and act. He addresses a host of issues, including discipline, learning, risk taking, aggression, sex, and drugs, and shows how boys and girls react in predictable ways to different situations. For example, girls are born with more sensitive hearing than boys, and those differences increase as kids grow up. So when a grown man speaks to a girl in what he thinks is a normal voice, she may hear it as yelling. Conversely, boys who appear to be inattentive in class may just be sitting too far away to hear the teacher—especially if the teacher is female. Likewise, negative emotions are seated in an ancient structure of the brain called the amygdala. Girls develop an early connection between this area and the cerebral cortex, enabling them to talk about their feelings. In boys these links develop later. So if you ask a troubled adolescent boy to tell you what his feelings are, he often literally cannot say.Dr. Sax offers fresh approaches to disciplining children, as well as gender-specific ways to help girls and boys avoid drugs and early sexual activity. He wants parents to understand and work with hardwired differences in children, but he also encourages them to push beyond gender-based stereotypes. A leading proponent of single-sex education, Dr. Sax points out specific instances where keeping boys and girls separate in the classroom has yielded striking educational, social, and interpersonal benefits. Despite the view of many educators and experts on child-rearing that sex differences should be ignored or overcome, parents and teachers would do better to recognize, understand, and make use of the biological differences that make a girl a girl, and a boy a boy.

    Now, at a moment when mathematicians are finally moving in on a proof, Dartmouth professor Dan Rockmore tells the riveting history of the hunt for a solution.In 1859 German professor Bernhard Riemann postulated a law capable of describing with an amazing degree of accuracy the occurrence of the prime numbers. Rockmore takes us all the way from Euclid to the mysteries of quantum chaos to show how the Riemann hypothesis lies at the very heart of some of the most cutting-edge research going on today in physics and mathematics.

    G. Wells' 1895 classic The Time Machine, readers of science fiction have puzzled over the paradoxes of time travel. What would happen if a time traveler tried to change history? Would some force or law of nature prevent him? Or would his action produce a "new" history, branching away from the original?In the last decade of the twentieth century a group of theoretical physicists at the California Institute of Technology undertook a serious investigation of the possibility of pastward time travel, inspiring a serious and sustained study that engaged more than thirty physicists working at universities and institutes around the world.Many of the figures involved are familiar: Einstein, Stephen Hawking and Kip Thorne; others are names known mostly to physicists. These are the new time travelers, and this is the story of their work--a profoundly human endeavor marked by advances, retreats, and no small share of surprises. It is a fantastic journey to the frontiers of physics.

    But it doesn't really. The moon revolves around the Earth. It takes about four weeks to make the journey, and as it travels round we can only see certain parts of it. Try the simple experiment described inside using an orange, a pencil, and a flashlight, and you'll understand why the moon seems to change.

    The easy kind, practiced by ants, shrimp, Welsh corgis -- and us -- is innate. What innate calculating skills do we humans have? Leaving aside built-in mathematics, such as the visual system, ordinary people do just fine when faced with mathematical tasks in the course of the day. Yet when they are confronted with the same tasks presented as "math," their accuracy often drops. But if we have innate mathematical ability, why do we have to teach math and why do most of us find it so hard to learn? Are there tricks or strategies that the ordinary person can do to improve mathematical ability? Can we improve our math skills by learning from dogs, cats, and other creatures that "do math"? The answer to each of these questions is a qualified yes. All these examples of animal math suggest that if we want to do better in the formal kind of math, we should see how it arises from natural mathematics. From NPR's "Math Guy" -- The Math Instinct will provide even the most number-phobic among us with confidence in our own mathematical abilities.
