    Harvey Karp reveals an extraordinary treasure sought by parents for centuries --an automatic “off-switch” for their baby’s crying.No wonder pediatricians across the country are praising him and thousands of Los Angeles parents, from working moms to superstars like Madonna and Pierce Brosnan, have turned to him to learn the secrets for making babies happy.Never again will parents have to stand by helpless and frazzled while their poor baby cries and cries. Dr. Karp has found there is a remedy for colic. “I share with parents techniques known only to the most gifted baby soothers throughout history …and I explain exactly how they work.”In an innovative and thought-provoking reevaluation of early infancy, Dr. Karp blends modern science and ancient wisdom to prove that newborns are not fully ready for the world when they are born. Through his research and experience, he has developed four basic principles that are crucial for understanding babies as well as improving their sleep and soothing their senses. ·The Missing Fourth Trimester: as odd as it may sound, one of the main reasons babies cry is because they are born three months too soon.·The Calming Reflex: the automatic reset switch to stop crying of any baby in the first few months of life.·The 5 “S’s”: the simple steps (swaddling, side/stomach position, shushing, swinging and sucking) that trigger the calming reflex. For centuries, parents have tried these methods only to fail because, as with a knee reflex, the calming reflex only works when it is triggered in precisely the right way. Unlike other books that merely list these techniques Dr. Karp teaches parents exactly how to do them, to guide cranky infants to calm and easy babies to serenity in minutes…and help them sleep longer too.·The Cuddle Cure: the perfect mix the 5 “S’s” that can soothe even the most colicky of infants.In the book, Dr. Karp also explains:What is colic?Why do most babies get much more upset in the evening?How can a parent calm a baby--in mere minutes?Can babies be spoiled?When should a parent of a crying baby call the doctor?How can a parent get their baby to sleep a few hours longer?Even the most loving moms and dads sometimes feel pushed to the breaking point by their infant’s persistent cries. Coming to the rescue, however, Dr. Karp places in the hands of parents, grandparents, and all childcare givers the tools they need to be able to calm their babies almost as easily as…turning off a light.

    It also proves troublesome for parents, as many are reminded of their own struggles with the subject and feel lost when trying to tackle it again years later in an effort to aid their offspring. Help Your Kids with Math is designed to reduce the stress of studying math for both children and adults. Using an appealing and uniquely accessible illustrative style, this book will show you what others only tell you, covering everything from basic arithmetic to more challenging subjects such as statistics, geometry, and algebra. Every aspect of math is explained in easily understandable language so that adults and kids can deal with the subject together. Tricky concepts are explored and examined step-by-step, so that even the most math-phobic individual will be able to approach complex problems with confidence.The first in an original new series of study aids that aims to demystify those subjects that seem tricky and incomprehensible, Math Survival provides invaluable guidance and easy explanations for all those desperate kids and parents who need to understand math and put it into practice.

    In Turing’s Cathedral, George Dyson focuses on a small group of men and women, led by John von Neumann at the Institute for Advanced Study in Princeton, New Jersey, who built one of the first computers to realize Alan Turing’s vision of a Universal Machine. Their work would break the distinction between numbers that mean things and numbers that do things—and our universe would never be the same. Using five kilobytes of memory (the amount allocated to displaying the cursor on a computer desktop of today), they achieved unprecedented success in both weather prediction and nuclear weapons design, while tackling, in their spare time, problems ranging from the evolution of viruses to the evolution of stars. Dyson’s account, both historic and prophetic, sheds important new light on how the digital universe exploded in the aftermath of World War II. The proliferation of both codes and machines was paralleled by two historic developments: the decoding of self-replicating sequences in biology and the invention of the hydrogen bomb. It’s no coincidence that the most destructive and the most constructive of human inventions appeared at exactly the same time.  How did code take over the world? In retracing how Alan Turing’s one-dimensional model became John von Neumann’s two-dimensional implementation, Turing’s Cathedral offers a series of provocative suggestions as to where the digital universe, now fully three-dimensional, may be heading next.

    Now, physicist Leonard Susskind has teamed up with data engineer Art Friedman to present the theory and associated mathematics of the strange world of quantum mechanics.In this follow-up to The Theoretical Minimum, Susskind and Friedman provide a lively introduction to this famously difficult field, which attempts to understand the behavior of sub-atomic objects through mathematical abstractions. Unlike other popularizations that shy away from quantum mechanics’ weirdness, Quantum Mechanics embraces the utter strangeness of quantum logic. The authors offer crystal-clear explanations of the principles of quantum states, uncertainty and time dependence, entanglement, and particle and wave states, among other topics, and each chapter includes exercises to ensure mastery of each area. Like The Theoretical Minimum, this volume runs parallel to Susskind’s eponymous Stanford University-hosted continuing education course.An approachable yet rigorous introduction to a famously difficult topic, Quantum Mechanics provides a tool kit for amateur scientists to learn physics at their own pace.

    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 are fueled by air and sun. And, like humans, trees are social. They “talk” to spread information; they share food and resources. They shelter and take care of one another. They are stronger together.
