But for those of us who left math behind in high school, the numbers and figures hurled at us as we go about our days can sometimes leave us scratching our heads and feeling as if we’re fumbling through a mathematical minefield. In this eye-opening and extraordinarily accessible book, mathemati­cian Kit Yates illuminates hidden principles that can help us understand and navigate the chaotic and often opaque surfaces of our world. In The Math of Life and Death, Yates takes us on a fascinating tour of everyday situations and grand-scale applications of mathematical concepts, including exponential growth and decay, optimization, statistics and probability, and number systems. Along the way he reveals the mathematical undersides of controversies over DNA testing, medical screening results, and historical events such as the Chernobyl disaster and the Amanda Knox trial. Readers will finish this book with an enlightened perspective on the news, the law, medicine, and history, and will be better equipped to make personal decisions and solve problems with math in mind, whether it’s choosing the shortest checkout line at the grocery store or halting the spread of a deadly disease.

    From the sudden expansion of a cloud of gas to the cooling of hot metal--everything is moved or restrained by four simple laws. Written by Peter Atkins, one of the world's leading authorities on thermodynamics, this powerful and compact introduction explains what these four laws are and how they work, using accessible language and virtually no mathematics. Guiding the reader a step at a time, Atkins begins with Zeroth (so named because the first two laws were well established before scientists realized that a third law, relating to temperature, should precede them--hence the jocular name zeroth), and proceeds through the First, Second, and Third Laws, offering a clear account of concepts such as the availability of work and the conservation of energy. Atkins ranges from the fascinating theory of entropy (revealing how its unstoppable rise constitutes the engine of the universe), through the concept of free energy, and to the brink, and then beyond the brink, of absolute zero. About the Series: Combining authority with wit, accessibility, and style, Very Short Introductions offer an introduction to some of life's most interesting topics. Written by experts for the newcomer, they demonstrate the finest contemporary thinking about the central problems and issues in hundreds of key topics, from philosophy to Freud, quantum theory to Islam.

    But the very existence of consciousness raises profound questions: Why would any collection of matter in the universe be conscious? How are we able to think about this? And why should we?In this wonderfully accessible book, Annaka Harris guides us through the evolving definitions, philosophies, and scientific findings that probe our limited understanding of consciousness. Where does it reside, and what gives rise to it? Could it be an illusion, or a universal property of all matter? As we try to understand consciousness, we must grapple with how to define it and, in the age of artificial intelligence, who or what might possess it. Conscious offers lively and challenging arguments that alter our ideas about consciousness—allowing us to think freely about it for ourselves, if indeed we can.

    Guy Leschziner's patients, there is no rest for the weary in mind and body. Insomnia, narcolepsy, night terrors, sleep apnea, and sleepwalking are just a sampling of conditions afflicting sufferers who cannot sleep--and their experiences in trying are the stuff of nightmares. Demoniac hallucinations frighten people into paralysis. Restless legs rock both the sleepless and their sleeping partners with unpredictable and uncontrollable kicking. Out-of-sync circadian rhythms confuse the natural body clock's days and nights.Then there are the extreme cases. A woman in a state of deep sleep who gets dressed, unlocks her car, and drives for several miles before returning to bed. The man who has spent decades cleaning out kitchens while "sleep-eating." The teenager prone to the serious, yet unfortunately nicknamed "Sleeping Beauty Syndrome" stuck in a cycle of excessive unconsciousness, binge eating, and uncharacteristic displays of aggression and hyper-sexuality while awake.With compassionate stories of his patients and their conditions, Dr. Leschziner illustrates the neuroscience behind our sleeping minds, revealing the many biological and psychological factors necessary in getting the rest that will not only maintain our physical and mental health, but improve our cognitive abilities and overall happiness.

    You might even be worried that these lapses in memory could be an early sign of Alzheimer's or dementia. In reality, for the vast majority of us, these examples of forgetting are completely normal. Why? Because while memory is amazing, it is far from perfect. Our brains aren't designed to remember every name we hear, plan we make, or day we experience. Just because your memory sometimes fails doesn't mean it's broken or succumbing to disease. Forgetting is actually part of being human. In Remember, neuroscientist and acclaimed novelist Lisa Genova delves into how memories are made and how we retrieve them. You'll learn whether forgotten memories are temporarily inaccessible or erased forever and why some memories are built to exist for only a few seconds (like a passcode) while others can last a lifetime (your wedding day). You'll come to appreciate the clear distinction between normal forgetting (where you parked your car) and forgetting due to Alzheimer's (that you own a car). And you'll see how memory is profoundly impacted by meaning, emotion, sleep, stress, and context. Once you understand the language of memory and how it functions, its incredible strengths and maddening weaknesses, its natural vulnerabilities and potential superpowers, you can both vastly improve your ability to remember and feel less rattled when you inevitably forget. You can set educated expectations for your memory, and in doing so, create a better relationship with it. You don't have to fear it anymore. And that can be life-changing.

    But if we are supposedly evolution’s greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there’s been some kind of mistake. As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them.   A rollicking, deeply informative tour of humans’ four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

    This may seem hard to accept, but, as Harari explains in his trademark style—thorough, yet riveting—famine, plague and war have been transformed from incomprehensible and uncontrollable forces of nature into manageable challenges. For the first time ever, more people die from eating too much than from eating too little; more people die from old age than from infectious diseases; and more people commit suicide than are killed by soldiers, terrorists and criminals put together. The average American is a thousand times more likely to die from binging at McDonalds than from being blown up by Al Qaeda.What then will replace famine, plague, and war at the top of the human agenda? As the self-made gods of planet earth, what destinies will we set ourselves, and which quests will we undertake? Homo Deus explores the projects, dreams and nightmares that will shape the twenty-first century—from overcoming death to creating artificial life. It asks the fundamental questions: Where do we go from here? And how will we protect this fragile world from our own destructive powers? This is the next stage of evolution. This is Homo Deus.With the same insight and clarity that made Sapiens an international hit and a New York Times bestseller, Harari maps out our future.

    Vividly bringing to life the latest scientific research in psychology, cognitive neuroscience, philosophy, and behavioral economics, Gilbert reveals what scientists have discovered about the uniquely human ability to imagine the future, and about our capacity to predict how much we will like it when we get there. With penetrating insight and sparkling prose, Gilbert explains why we seem to know so little about the hearts and minds of the people we are about to become.

    Whether you’re deciding which smart phone to purchase or which politician to believe, you think you are a rational being whose every decision is based on cool, detached logic, but here’s the truth: You are not so smart. You’re just as deluded as the rest of us--but that’s okay, because being deluded is part of being human. Growing out of David McRaney’s popular blog, You Are Not So Smart reveals that every decision we make, every thought we contemplate, and every emotion we feel comes with a story we tell ourselves to explain them, but often these stories aren’t true. Each short chapter--covering topics such as Learned Helplessness, Selling Out, and the Illusion of Transparency--is like a psychology course with all the boring parts taken out.Bringing together popular science and psychology with humor and wit, You Are Not So Smart is a celebration of our irrational, thoroughly human behavior.

    Lieberman illuminates how these ongoing changes have brought many benefits, but also have created novel conditions to which our bodies are not entirely adapted, resulting in a growing incidence of obesity and new but avoidable diseases, including type-2 diabetes. He proposes that many of these chronic illnesses persist and in some cases are intensifying because of "dysevolution," a pernicious dynamic whereby only the symptoms rather than the causes of these maladies are treated. And finally—provocatively—he advocates the use of evolutionary information to help nudge, push, and sometimes oblige us to create a more salubrious environment.(With charts and line drawings throughout.)From the Hardcover edition.

    The new nanny gives a mother an uneasy feeling. A stranger in a deserted parking lot offers unsolicited help. The threat of violence surrounds us every day. But we can protect ourselves, by learning to trust—and act on—our gut instincts.In this empowering book, Gavin de Becker, the man Oprah Winfrey calls the nation's leading expert on violent behavior, shows you how to spot even subtle signs of danger—before it's too late. Shattering the myth that most violent acts are unpredictable, de Becker, whose clients include top Hollywood stars and government agencies, offers specific ways to protect yourself and those you love, including how to act when approached by a stranger, when you should fear someone close to you, what to do if you are being stalked, how to uncover the source of anonymous threats or phone calls, the biggest mistake you can make with a threatening person, and more. Learn to spot the danger signals others miss. It might just save your life.

    His previous books, including the Pulitzer Prize finalist The Blank Slate, have catapulted him into the limelight as one of today's most important and popular science writers. Now, in The Stuff of Thought, Pinker marries two of the subjects he knows best: language and human nature. The result is a fascinating look at how our words explain our nature. What does swearing reveal about our emotions? Why does innuendo disclose something about relationships? Pinker reveals how our use of prepositions and tenses taps into peculiarly human concepts of space and time, and how our nouns and verbs speak to our notions of matter. Even the names we give our babies have important things to say about our relations to our children and to society. With his signature wit and style, Pinker takes on scientific questions like whether language affects thought, as well as forays into everyday life: why is bulk e-mail called spam and how do romantic comedies get such mileage out of the ambiguities of dating? The Stuff of Thought is a brilliantly crafted and highly readable work that will appeal to fans of readers of everything from The Selfish Gene and Blink to Eats, Shoots & Leaves.

    In pursuit of these things, it is undeterred by emotion, fear, or morality. Dopamine is the source of our every urge, that little bit of biology that makes an ambitious business professional sacrifice everything in pursuit of success, or that drives a satisfied spouse to risk it all for the thrill of someone new. Simply put, it is why we seek and succeed; it is why we discover and prosper. Yet, at the same time, it’s why we gamble and squander. From dopamine’s point of view, it’s not the having that matters. It’s getting something—anything—that’s new. From this understanding—the difference between possessing something versus anticipating it—we can understand in a revolutionary new way why we behave as we do in love, business, addiction, politics, religion – and we can even predict those behaviors in ourselves and others. In The Molecule of More: How a Single Chemical in Your Brain Drives Love, Sex, and Creativity—and will Determine the Fate of the Human Race, George Washington University professor and psychiatrist Daniel Z. Lieberman, MD, and Georgetown University lecturer Michael E. Long present a potentially life-changing proposal: Much of human life has an unconsidered component that explains an array of behaviors previously thought to be unrelated, including why winners cheat, why geniuses often suffer with mental illness, why nearly all diets fail, and why the brains of liberals and conservatives really are different.

    Augustine equate nothingness with the Devil? What tortuous means did 17th-century scientists employ in their attempts to create a vacuum? And why do contemporary quantum physicists believe that the void is actually seething with subatomic activity? You’ll find the answers in this dizzyingly erudite and elegantly explained book by the English cosmologist John D. Barrow.Ranging through mathematics, theology, philosophy, literature, particle physics, and cosmology, The Book of Nothing explores the enduring hold that vacuity has exercised on the human imagination. Combining high-wire speculation with a wealth of reference that takes in Freddy Mercury and Shakespeare alongside Isaac Newton, Albert Einstein, and Stephen Hawking, the result is a fascinating excursion to the vanishing point of our knowledge.

    Having just completed his masterpiece, The General Theory of Relativity—which provided a brand-new theory of gravity and promised a new perspective on the cosmos as a whole—he set out at once to share his excitement with as wide a public as possible in this popular and accessible book.Here published for the first time as a Penguin Classic, this edition of Relativity features a new introduction by bestselling science author Nigel Calder.
