For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born. From the invention of scripts and alphabets to the long-misunderstood talking drums of Africa, Gleick tells the story of information technologies that changed the very nature of human consciousness. He provides portraits of the key figures contributing to the inexorable development of our modern understanding of information: Charles Babbage, the idiosyncratic inventor of the first great mechanical computer; Ada Byron, the brilliant and doomed daughter of the poet, who became the first true programmer; pivotal figures like Samuel Morse and Alan Turing; and Claude Shannon, the creator of information theory itself. And then the information age arrives. Citizens of this world become experts willy-nilly: aficionados of bits and bytes. And we sometimes feel we are drowning, swept by a deluge of signs and signals, news and images, blogs and tweets. The Information is the story of how we got here and where we are heading.

    Children are hyper-aware of money, and they have scores of questions about its nuances. But when parents shy away from the topic, they lose a tremendous opportunity—not just to model the basic financial behaviors that are increasingly important for young adults but also to imprint lessons about what the family truly values.Written in a warm, accessible voice, grounded in real-world experience and stories from families with a range of incomes, The Opposite of Spoiled is both a practical guidebook and a values-based philosophy. The foundation of the book is a detailed blueprint for the best ways to handle the basics: the tooth fairy, allowance, chores, charity, saving, birthdays, holidays, cell phones, checking accounts, clothing, cars, part-time jobs, and college tuition. It identifies a set of traits and virtues that embody the opposite of spoiled, and shares how to embrace the topic of money to help parents raise kids who are more generous and less materialistic.But The Opposite of Spoiled is also a promise to our kids that we will make them better with money than we are. It is for all of the parents who know that honest conversations about money with their curious children can help them become more patient and prudent, but who don’t know how and when to start.

    . . on childhood. As the pace of life accelerates to hyperspeed–with too much stuff, too many choices, and too little time–children feel the pressure. They can become anxious, have trouble with friends and school, or even be diagnosed with behavioral problems. Now, in defense of the extraordinary power of less, internationally renowned family consultant Kim John Payne helps parents reclaim for their children the space and freedom that all kids need, allowing their children’s attention to focus and their individuality to flourish.Based on Payne’s twenty year’s experience successfully counseling busy families, Simplicity Parenting teaches parents how to worry and hover less–and how to enjoy more. For those who want to slow their children’s lives down but don’t know where to start, Payne offers both inspiration and a blueprint for change.• Streamline your home environment. The average child has more than 150 toys. Here are tips for reducing the amount of toys, books, and clutter–as well as the lights, sounds, and general sensory overload that crowd the space young imaginations need in order to grow.• Establish rhythms and rituals. Predictability (routines) and transparency (knowing the day’s plan) are soothing pressure valves for children. Here are ways to ease daily tensions, create battle-free mealtimes and bedtimes, and tell if your child is overwhelmed.• Schedule a break in the schedule. Too many activities may limit children’s ability to motivate and direct themselves. Learn how to establish intervals of calm in your child’s daily torrent of constant doing–and familiarize yourself with the pros and cons of organized sports and other “enrichment” activities.• Scale back on media and parental involvement. Back out of hyperparenting by managing your children’s “screen time” to limit the endless and sometimes scary deluge of information and stimulation. Parental hovering is really about anxiety; by doing less and trusting more, parents can create a sanctuary that nurtures children’s identity, well-being, and resiliency as they grow–slowly–into themselves. A manifesto for protecting the grace of childhood, Simplicity Parenting is an eloquent guide to bringing new rhythms to bear on the lifelong art of parenting.

    Once they are mastered, these skills allow reduced adult supervision.

    Just read this till the end You don’t have to buy this book. Just read this till end & you will learn something that will change the way you do math forever. Warning: I am revealing this secret only to the first set of readers who will buy this book & plan to put this secret back inside the book once I have enough sales. So read this until the very end while you still can.School taught you the wrong way to do mathThe way you were taught to do math, uses a lot of working memory. Working memory is the short term memory used to complete a mental task. You struggle because trying to do mental math the way you were taught in school, overloads your working memory. Let me show you what I mean with an example:Try to multiply the 73201 x 3. To do this you multiply the following:1 x 3 =0 x 3 =2 x 3 =3 x 3 =7 x 3 =This wasn’t hard, & it might have taken you just seconds to multiply the individual numbers. However, to get the final answer, you need to remember every single digit you calculated to put them back together. It takes effort to get the answer because you spend time trying to recall the numbers you already calculated. Math would be easier to do in your head if you didn’t have to remember so many numbers. Imagine when you tried to multiply 73201 x 3, if you could have come up with the answer, in the time it took you to multiply the individual numbers. Wouldn’t you have solved the problem faster than the time it would have taken you to punch in the numbers inside a calculator? Do the opposite of what you were taught in schoolThe secret of doing mental math is to calculate from left to right instead of from right to left. This is the opposite of what you were taught in school. This works so well because it frees your working memory almost completely. It is called the LR Method where LR stands for Left to Right.Lets try to do the earlier example where we multiplied 73201 x 3. This time multiply from left to right, so we get:7 x 3 = 213 x 3 = 93 x 2 = 60 x 3 = 03 x 1 = 3Notice that you started to call out the answer before you even finished the whole multiplication problem. You don’t have to remember a thing to recall & use later. So you end up doing math a lot faster. The Smart ChoiceYou could use what you learnt & apply it to solve math in the future. This might not be easy, because we just scratched the surface. I've already done the work for you. Why try to reinvent the wheel, when there is already a proven & tested system you can immediately apply.

    What if everything you knew about education was wrong? is just a title. Of course, you probably think a great many things that aren't wrong. The aim of the book is to help you 'murder your darlings'. David Didau will question your most deeply held assumptions about teaching and learning, expose them to the fiery eye of reason and see if they can still walk in a straight line after the experience. It seems reasonable to suggest that only if a theory or approach can withstand the fiercest scrutiny should it be encouraged in classrooms. David makes no apologies for this; why wouldn't you be sceptical of what you're told and what you think you know? As educated professionals, we ought to strive to assemble a more accurate, informed or at least considered understanding of the world around us. Here, David shares with you some tools to help you question your assumptions and assist you in picking through what you believe. He will stew findings from the shiny white laboratories of cognitive psychology, stir in a generous dash of classroom research and serve up a side order of experience and observation. Whether you spit it out or lap it up matters not. If you come out the other end having vigorously and violently disagreed with him, you'll at least have had to think hard about what you believe. The book draws on research from the field of cognitive science to expertly analyse some of the unexamined meta-beliefs in education. In Part 1; 'Why we're wrong', David dismantles what we think we know; examining cognitive traps and biases, assumptions, gut feelings and the problem of evidence. Part 2 delves deeper - 'Through the threshold' - looking at progress, liminality and threshold concepts, the science of learning, and the difference between novices and experts. In Part 3, David asks us the question 'What could we do differently?' and offers some considered insights into spacing and interleaving, the testing effect, the generation effect, reducing feedback and why difficult is desirable. While Part 4 challenges us to consider 'What else might we be getting wrong?'; cogitating formative assessment, lesson observation, grit and growth, differentiation, praise, motivation and creativity.

    She shows how the development of the brain can affect future emotional well being, and goes on to look at specific early 'pathways' that can affect the way we respond to stress and lead to conditions such as anorexia, addiction, and anti-social behaviour.Why Love Matters is a lively and very accessible interpretation of the latest findings in neuroscience, psychology, psychoanalysis and biochemistry. It will be invaluable to psychotherapists and psychoanalysts, mental health professionals, parents and all those concerned with the central importance of brain development in relation to many later adult difficulties.

    Tobias Dantzig shows that the development of math—from the invention of counting to the discovery of infinity—is a profoundly human story that progressed by “trying and erring, by groping and stumbling.” He shows how commerce, war, and religion led to advances in math, and he recounts the stories of individuals whose breakthroughs expanded the concept of number and created the mathematics that we know today.

    Untangled explains what’s going on, prepares parents for what’s to come, and lets them know when it’s time to worry. In this sane, highly engaging, and informed guide for parents of daughters, Dr. Damour draws on decades of experience and the latest research to reveal the seven distinct—and absolutely normal—developmental transitions that turn girls into grown-ups, including Parting with Childhood, Contending with Adult Authority, Entering the Romantic World, and Caring for Herself. Providing realistic scenarios and welcome advice on how to engage daughters in smart, constructive ways, Untangled gives parents a broad framework for understanding their daughters while addressing their most common questions, including • My thirteen-year-old rolls her eyes when I try to talk to her, and only does it more when I get angry with her about it. How should I respond? • Do I tell my teen daughter that I’m checking her phone? • My daughter suffers from test anxiety. What can I do to help her? • Where’s the line between healthy eating and having an eating disorder? • My teenage daughter wants to know why I’m against pot when it’s legal in some states. What should I say? • My daughter’s friend is cutting herself. Do I call the girl’s mother to let her know? Perhaps most important, Untangled helps mothers and fathers understand, connect, and grow with their daughters. When parents know what makes their daughter tick, they can embrace and enjoy the challenge of raising a healthy, happy young woman.Praise for Untangled“Finally, there’s some good news for puzzled parents of adolescent girls, and psychologist Lisa Damour is the bearer of that happy news. [Untangled] is the most down-to-earth, readable parenting book I’ve come across in a long time.”—The Washington Post “Anna Freud wrote in 1958, ‘There are few situations in life which are more difficult to cope with than an adolescent son or daughter during the attempt to liberate themselves.’ In the intervening decades, the transition doesn’t appear to have gotten any easier which makes Untangled such a welcome new resource.”—The Boston Globe “Damour offers a hopeful, helpful new way for parents to talk about—and with—teenage girls. . . . Parents will want this book on their shelves, next to established classics of the genre.”—Publishers Weekly“For years people have been asking me for the ‘girl equivalent of Raising Cain,’ and I haven't known exactly what to recommend. Now I do.”—Michael Thompson, Ph.D., co-author of Raising Cain “An essential guide to understanding and supporting girls throughout their development. It’s obvious that Dr. Damour ‘gets’ girls and understands the best way for any adult to help them navigate the common yet difficult challenges so many girls face.”—Rosalind Wiseman, author of Queen Bees & Wannabes “A gem. From the moment I read the last page I’ve been recommending it to my clients (including those with sons!) and colleagues, and using it as a refreshing guide in my own work with teenagers and their parents.”—Wendy Mogel, Ph.D., author of The Blessing of a Skinned Knee

    Len Fisher turns his attention to the science of cooperation in his lively and thought-provoking book. Fisher shows how the modern science of game theory has helped biologists to understand the evolution of cooperation in nature, and investigates how we might apply those lessons to our own society. In a series of experiments that take him from the polite confines of an English dinner party to crowded supermarkets, congested Indian roads, and the wilds of outback Australia, not to mention baseball strategies and the intricacies of quantum mechanics, Fisher sheds light on the problem of global cooperation. The outcomes are sometimes hilarious, sometimes alarming, but always revealing. A witty romp through a serious science, Rock, Paper, Scissors will both teach and delight anyone interested in what it what it takes to get people to work together.
