Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that Pluto was a planet. For decades, we were convinced that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing.   But it turns out there’s an order to the state of knowledge, an explanation for how we know what we know. Samuel Arbesman is an expert in the field of scientometrics—literally the science of science. Knowl­edge in most fields evolves systematically and predict­ably, and this evolution unfolds in a fascinating way that can have a powerful impact on our lives.   Doctors with a rough idea of when their knowl­edge is likely to expire can be better equipped to keep up with the latest research. Companies and govern­ments that understand how long new discoveries take to develop can improve decisions about allocating resources. And by tracing how and when language changes, each of us can better bridge gen­erational gaps in slang and dialect.   Just as we know that a chunk of uranium can break down in a measurable amount of time—a radioactive half-life—so too any given field’s change in knowledge can be measured concretely. We can know when facts in aggregate are obsolete, the rate at which new facts are created, and even how facts spread.   Arbesman takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries. He shows that much of what we know consists of “mesofacts”—facts that change at a middle timescale, often over a single human lifetime. Throughout, he of­fers intriguing examples about the face of knowledge: what English majors can learn from a statistical analysis of The Canterbury Tales, why it’s so hard to measure a mountain, and why so many parents still tell kids to eat their spinach because it’s rich in iron.   The Half-life of Facts is a riveting journey into the counterintuitive fabric of knowledge. It can help us find new ways to measure the world while accepting the limits of how much we can know with certainty.

    It is Lorayne's 14th book on the subject of memory. You are treated to the proven techniques and methods of a professional, as you are shown how to use your mind to its fullest capacity.

    In How Not to Be Wrong, Jordan Ellenberg shows us how terribly limiting this view is: Math isn’t confined to abstract incidents that never occur in real life, but rather touches everything we do—the whole world is shot through with it.Math allows us to see the hidden structures underneath the messy and chaotic surface of our world. It’s a science of not being wrong, hammered out by centuries of hard work and argument. Armed with the tools of mathematics, we can see through to the true meaning of information we take for granted: How early should you get to the airport? What does “public opinion” really represent? Why do tall parents have shorter children? Who really won Florida in 2000? And how likely are you, really, to develop cancer?How Not to Be Wrong presents the surprising revelations behind all of these questions and many more, using the mathematician’s method of analyzing life and exposing the hard-won insights of the academic community to the layman—minus the jargon. Ellenberg chases mathematical threads through a vast range of time and space, from the everyday to the cosmic, encountering, among other things, baseball, Reaganomics, daring lottery schemes, Voltaire, the replicability crisis in psychology, Italian Renaissance painting, artificial languages, the development of non-Euclidean geometry, the coming obesity apocalypse, Antonin Scalia’s views on crime and punishment, the psychology of slime molds, what Facebook can and can’t figure out about you, and the existence of God.Ellenberg pulls from history as well as from the latest theoretical developments to provide those not trained in math with the knowledge they need. Math, as Ellenberg says, is “an atomic-powered prosthesis that you attach to your common sense, vastly multiplying its reach and strength.” With the tools of mathematics in hand, you can understand the world in a deeper, more meaningful way. How Not to Be Wrong will show you how.

     What makes a good life? Is it money? An important job? Leisure time? Mihaly Csikszentmihalyi believes our obsessive focus on such measures has led us astray. Work fills our days with anxiety and pressure, so that during our free time, we tend to live in boredom, watching TV or absorbed by our phones.What are we missing? To answer this question, Csikszentmihalyi studied thousands of people, and he found the key. People are happiest when they challenge themselves with tasks that demand a high degree of skill and commitment, and which are undertaken for their own sake. Instead of watching television, play the piano. Take a routine chore and figure out how to do it better, faster, more efficiently. In short, learn the hidden power of complete engagement, a psychological state the author calls flow. Though they appear simple, the lessons in Finding Flow are life-changing.

    Scientists now know that the human brain is undergoing a constant and dramatic transformation in the first years of life. During this peak time of development, every activity and experience leaves an indelible mark on your baby’s brain, for better or worse. The right kind of stimulation and nutrition will create connections in the brain that promote intelligence and raise IQ. The wrong kinds of activities and foods can stifle intellectual development, destroy brain cells, and leave your child more vulnerable to learning or behavior problems down the road. So, what can you do during the first five years to ensure that your child is primed to excel?The good news is that raising a smarter child is easier than you think. It doesn’t require making an investment in expensive equipment or high priced tutors. It’s as simple as playing the right games, serving the right foods, and maintaining a brain-enhancing environment in your home by eliminating common household toxins. In Raise a Smarter Child by Kindergarten by Dr. David Perlmutter, you’ll learn easy and highly effective strategies that can vastly improve your child’s brain power and reduce his or her chances of developing ADD and ADHD. For example, you can:• Stimulate Memory: Changing a component on the over-the-crib mobile every week makes the baby compare what was there before to what’s there now, reinforcing memory pathways in the brain that are critical for learning.• Spread out those shots: Schedule more frequent trips to the pediatrician for vaccinations, so that fewer shots are administered at once. Flooding the immune system with a cocktail of different vaccines can damage the nervous system. • Get rid of toxins: Protecting a child from neurotoxins found in foods, toys and even baby bottles can help preserve precious IQ points. Dr. Perlmutter provides a scientifically backed food and supplement plan for children and nursing mothers and details the many brain-building activities that you can do with your child. In addition, he reveals the numerous toys and household products that contain harmful, brain-damaging toxins and shows how to identify and combat common childhood problems like ADD and food allergies that may affect your child’s development. Your job over the first five years is to help your child build the best brain possible. With Dr. Perlmutter’s help, you can mine the countless opportunities you have each day to make your child smarter, happier and better prepared to excel.

    Bipolar II disorder differs from bipolar I in that sufferers may never experience a full manic episode, although they may experience periods of high energy and impulsiveness (hypomania), as well as depression and anxiety.

Fortunately, there are proven-effective treatments that can help you find a sense of calm and peace of mind. Written by an extremely accomplished team of bipolar experts, The Bipolar II Disorder Workbook is designed to help you manage the recurring depression, hypomania, and anxiety that can arise as a result of your condition. The convenient workbook format combines evidence-based cognitive behavioral therapy (CBT), dialectical behavioral therapy (DBT), and other mindfulness-based exercises to help you manage your emotions, track your progress, and ultimately live a happy and more productive life. This is the first self-help workbook available specifically for individuals diagnosed with bipolar II disorder.

    Gallagher grapples with provocative questions—Can we train our focus? What’s different about the way creative people pay attention? Why do we often zero in on the wrong factors when making big decisions, like where to move?—driving us to reconsider what we think we know about attention. Gallagher looks beyond sound bites on our proliferating BlackBerries and the increased incidence of ADD in children to the discoveries of neuroscience and psychology and the wisdom of home truths, profoundly altering and expanding the contemporary conversation on attention and its power. Science’s major contribution to the study of attention has been the discovery that its basic mechanism is an either/or process of selection. That we focus may be a biological necessity— research now proves we can process only a little information at a time, or about 173 billion bits over an average life—but the good news is that we have much more control over our focus than we think, which gives us a remarkable yet underappreciated capacity to influence our experience. As suggested by the expression “pay attention,” this cognitive currency is a finite resource that we must learn to spend wisely. In Rapt, Gallagher introduces us to a diverse cast of characters—artists and ranchers, birders and scientists—who have learned to do just that and whose stories are profound lessons in the art of living the interested life. No matter what your quotient of wealth, looks, brains, or fame, increasing your satisfaction means focusing more on what really interests you and less on what doesn’t. In asserting its groundbreaking thesis—the wise investment of your attention is the single most important thing you can do to improve your well-being—Rapt yields fresh insights into the nature of reality and what it means to be fully alive.

    Rudolf Steiner describes how each person's combination of temperaments is shaped out of a particular kind of union between hereditary factors and the inner spiritual nature. Telling descriptions are provided for the inwardly comfortable phlegmatic, the fickle interest of the sanguine, the pained and gloomy melancholic, and the fiery, assertive choleric. Steiner also offers practical suggestions for guiding the temperaments educationally in childhood and for adult self-improvement.
