    In her groundbreaking new book, Sian Beilock, author of the highly acclaimed Choke, which Time magazine praised for its “smart tips...in order to think clearly...and be cool under pressure,” draws on her own cutting-edge research to turn the conventional understanding of the mind upside down in ways that will revolutionize how we live our lives. At the heart of How the Body Knows Its Mind is the tantalizing idea that our bodies “hack” our brains. The way we move affects our thoughts, our decisions, and even our preferences for particular products. Called “embodied cognition,” this new science—of which Beilock is a foremost researcher—illuminates the power of the body and its physical surroundings to shape how we think, feel, and behave. Beilock’s findings are as varied as they are surprising. For example, pacing around the room can enhance creativity; gesturing during a speech can help ensure that you don’t draw a blank; kids learn better when their bodies are part of the learning process; walking in nature boosts concentration skills; Botox users experience less depression; and much more. From the tricks used by advertisers to the ways body language can improve your memory, Beilock explains a wealth of fascinating interconnections between mind and body and how mastering them can make us happier, safer, and more successful.

    Paxil. Zoloft. Turn on your television and you are likely to see a commercial for one of the many selective serotonin reuptake inhibitors (SSRIs) on the market. We hear a lot about them, but do we really understand how these drugs work and what risks are involved for anyone who uses them?Let Them Eat Prozac explores the history of SSRIs from their early development to their latest marketing campaigns and the controversies that surround them. Initially, they seemed like wonder drugs for those with mild to moderate depression patients take just one daily dose, and unlike the tranquilizers that were popular in the 1960s, they supposedly did not lead to addiction. When Prozac was released in the late 1980s, David Healy was among the psychiatrists who prescribed it. But he soon observed that some of these patients became agitated and even attempted suicide. Studies were soon published, citing numerous cases in which patients became anxious and reported increased suicidal thoughts while taking Prozac. Could the new wonder drug actually be making patients worse?Healy draws on his own research and expertise to demonstrate the potential hazards associated with these drugs. He intersperses case histories with insider accounts of the research leading to the development and approval of SSRIs as a treatment for depression. Let Them Eat Prozac clearly demonstrates that the problems go much deeper than a disturbing side-effect of a particular drug. Current FDA regulations encourage drug companies to patent a specific compound and market it effectively to a large population on the basis of minimal effectiveness in a handful of trials.The pharmaceutical industry would like us to believe that SSRIs can safely treat depression, anxiety, and a host of other mental problems. But as Let Them Eat Prozac reveals, this "cure" may be worse than the disease.

    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.

    This user-friendly self-study guide is aimed at the general reader who is motivated to tackle that not insignificant challenge. The book is written using straightforward and accessible language, with clear derivations and explanations as well as numerous fully solved problems. For those with minimal mathematical background, the first chapter provides a crash course in foundation mathematics. The reader is then taken gently by the hand and guided through a wide range of fundamental topics, including Newtonian mechanics; the Lorentz transformations; tensor calculus; the Einstein field equations; the Schwarzschild solution (which gives a good approximation of the spacetime of our Solar System); simple black holes and relativistic cosmology. Following the historic 2015 LIGO (Laser Interferometer Gravitational-Wave Observatory) detection, there is now an additional chapter on gravitational waves, ripples in the fabric of spacetime that potentially provide a revolutionary new way to study the universe. Special relativity helps explain a huge range of non-gravitational physical phenomena and has some strangely counter-intuitive consequences. These include time dilation, length contraction, the relativity of simultaneity, mass-energy equivalence and an absolute speed limit. General relativity, the leading theory of gravity, is at the heart of our understanding of cosmology and black holes.Understand even the basics of Einstein's amazing theory and the world will never seem the same again.

    There is no A-to-Z path, and there are no magic beans that will carry you upward overnight. Have you ever wondered how to start, scale up, build teams, and flourish in an uncontested market? I can tell you. I did it. In 1992, I landed in Estonia with $400 in my pocket. There, I discovered a truth that changed my life and the way I conducted business: You can make a lot of money as an entrepreneur by moving decisively in blue-sky markets - markets where you face very little competition and the tide can carry you to riches.Over the next decade and a half, I built a portfolio of businesses worth $200 million. Now, I want to share the paths that led me to success, passing on my knowledge to you. In Why Sell Tacos in Africa? I explain sixteen principles that allowed me to drive such tremendous growth. May you, too, find a blue-market and watch your business soar.

    Dairy products don't strengthen bones. Drugs may be dangerous.For years, doctors have been telling us to drink milk, eat dairy products, and take calcium pills to improve our bone vitality. The problem is, they're wrong. This groundbreaking guide uses the latest clinical studies and the most up-to-date medical information to help you strengthen your bones, reduce the risk of fractures, and prevent osteoporosis. You'll learn why there's no proof of calcium's effectiveness, despite what doctors say, and why a low-acid diet is the only effective way to prevent bone loss."This clear, convincing explanation of osteoporosis will change the way the world thinks about bone health. Lanou and Castleman prove beyond doubt that milk and dairy are the problem, not the solution." -Rory Freedman, coauthor of #1 New York Times best seller Skinny Bitch"The authors have tackled an almost intractable myth: that calcium is the one and only key to bone vitality. It isn't. Everyone who cares about preventing osteoporosis should read this book." -- Dr. T. Colin Campbell, author of The China Study

    In The Book on Making Money, he reveals what he learned while successfully hitting this goal for seven years in a row, growing his annual income to more than $1 million. Walking readers through the steps he took to reach his goal, Oliverez shows how they can apply the same techniques to greatly increase their own income, whether they work for someone else or run their own business. Oliverez spells out his disagreements with the traditional wisdom that tells young adults to go to school, get good grades and find a safe, steady job - advice that has left many Americans with tens or hundreds of thousands of dollars in student loans, credit card debt or mortgages on homes they can't afford. He also assaults the idea of saving one’s way to wealth as absurd and counterproductive, using his own experience of trying to save money while poor as an example. Instead of promoting an austere lifestyle of clipping coupons and spending as little as possible, he shows how those habits can actually prevent people from becoming wealthy. Perhaps your goal is to create passive income, launch a startup or make money investing in the stock market. Maybe you're still an employee and you want to learn how to write a better resume, ask for a raise, and budget so you can get out of debt. This straight-forward guide will teach you how money works and give you the tools to achieve financial freedom.

    He was about to stand in front of the employees of the Happy Face Toy Company’s faltering Cleveland factory. As the new CEO, he’d been advised to close this factory as soon as possible, but he wanted to see it first. “How hard could this be?” he wondered, gathering the courage to ask them about their jobs.  He had no idea what he was in for. When was the last time you told your colleagues how much you value them? It sounds like a trivial thing in the middle of a busy work day. But as David Novak discovered during his years as a hard charging executive, there’s nothing trivial about recognition. It can make a life-or-death difference to any organization, when people see that someone important really notices and appreciates their contributions.  Rather than explain the power of recognition in a typical business book, Novak decided to write a fun story that draws on his real-world experiences at Pepsi and Yum! Brands, as well as his personal life. The story opens when Jeff Johnson becomes the third-generation CEO of his family business, after the sudden death of his father. The Happy Face Toy Company had many hits in the 1950s and 60s, including Crazy Paste, but its results have been declining for more than a decade. The board has given Jeff just one year to turn the business around, or else they’ll have to sell it to the highest bidder.  As Jeff races to save his family’s legacy by getting the company back on track, he meets downtrodden factory workers and an uninspired executive team. Then a birthday gift from his own grandson gives Jeff an important insight into why Happy Face lost its old culture of innovation and excitement, along with its profitability.  Jeff comes up with an idea that seems crazy… But is it crazy enough to work?  Whether you’re trying to lead a small department, a Fortune 500 company, a non-profit, or your own family, the lessons at the heart of O Great One! can help you make everyone around you happier and more effective.
