In this book you will see how commonly performed operations can be found to be useless or even harmful when properly evaluated. That these claims come from an experienced, practicing orthopedic surgeon who performs many of these operations himself, makes the unsettling argument particularly compelling. Of course no surgeon is recommending invasive surgery in bad faith, but Ian Harris argues that the evidence for the success for many common operations, including knee arthroscopies, back fusion or cardiac stenting, become current accepted practice without full examination of the evidence.

    But while this medieval medicine now seems archaic, it also made a critical contribution to modern science.Medieval Bodies guides us on a head-to-heel journey through this era’s revolutionary advancements and disturbing convictions. We learn about the surgeons who dissected a living man’s stomach, then sewed him up again; about the geographers who delineated racial groups by skin color; and about the practice of fasting to gain spiritual renown. Encompassing medicine and mysticism, politics and art—and complete with vivid, full-color illustrations—Medieval Bodies shows us how it felt to live and die a thousand years ago.

    In all the current highly publicized debates about creationism and its descendant "intelligent design," there is an element of the controversy that is rarely mentioned—the "evidence," the empirical truth of evolution by natural selection. Even Richard Dawkins and Stephen Jay Gould, while extolling the beauty of evolution and examining case studies, have not focused on the evidence itself. Yet the proof is vast, varied, and magnificent, drawn from many different fields of science. Scientists are observing species splitting into two and are finding more and more fossils capturing change in the past—dinosaurs that have sprouted feathers, fish that have grown limbs. Why Evolution Is True weaves together the many threads of modern work in genetics, paleontology, geology, molecular biology, and anatomy that demonstrate the "indelible stamp" of the processes first proposed by Darwin. In crisp, lucid prose accessible to a wide audience, Why Evolution Is True dispels common misunderstandings and fears about evolution and clearly confirms that this amazing process of change has been firmly established as a scientific truth.

    However, according to Hofstadter, the formal system that underlies all mental activity transcends the system that supports it. If life can grow out of the formal chemical substrate of the cell, if consciousness can emerge out of a formal system of firing neurons, then so too will computers attain human intelligence. Gödel, Escher, Bach is a wonderful exploration of fascinating ideas at the heart of cognitive science: meaning, reduction, recursion, and much more.

    Why do we recognize patterns? Is there such a thing as positive stress? Are we genetically programmed to be in conflict with each other? Those are just some of the 150 questions that the world's best scientific minds answer with elegant simplicity.With contributions from Jared Diamond, Richard Dawkins, Nassim Taleb, Brian Eno, Steven Pinker, and more, everything is explained in fun, uncomplicated terms that make the most complex concepts easy to comprehend.

    It was the dawn of a new era in artificial intelligence: a machine capable of beating the reigning human champion at this most cerebral game. That moment was more than a century in the making, and in this breakthrough book, Kasparov reveals his astonishing side of the story for the first time. He describes how it felt to strategize against an implacable, untiring opponent with the whole world watching, and recounts the history of machine intelligence through the microcosm of chess, considered by generations of scientific pioneers to be a key to unlocking the secrets of human and machine cognition. Kasparov uses his unrivaled experience to look into the future of intelligent machines and sees it bright with possibility. As many critics decry artificial intelligence as a menace, particularly to human jobs, Kasparov shows how humanity can rise to new heights with the help of our most extraordinary creations, rather than fear them. Deep Thinking is a tightly argued case for technological progress, from the man who stood at its precipice with his own career at stake.

    The controversial book linking intelligence to class and race in modern society, and what public policy can do to mitigate socioeconomic differences in IQ, birth rate, crime, fertility, welfare, and poverty.

    But modern times have forced the world’s tribes into a shared space, resulting in epic clashes of values along with unprecedented opportunities. As the world shrinks, the moral lines that divide us become more salient and more puzzling. We fight over everything from tax codes to gay marriage to global warming, and we wonder where, if at all, we can find our common ground. A grand synthesis of neuroscience, psychology, and philosophy, Moral Tribes reveals the underlying causes of modern conflict and lights the way forward. Greene compares the human brain to a dual-mode camera, with point-and-shoot automatic settings (“portrait,” “landscape”) as well as a manual mode. Our point-and-shoot settings are our emotions—efficient, automated programs honed by evolution, culture, and personal experience. The brain’s manual mode is its capacity for deliberate reasoning, which makes our thinking flexible. Point-and-shoot emotions make us social animals, turning Me into Us. But they also make us tribal animals, turning Us against Them. Our tribal emotions make us fight—sometimes with bombs, sometimes with words—often with life-and-death stakes. An award-winning teacher and scientist, Greene directs Harvard University’s Moral Cognition Lab, which uses cutting-edge neuroscience and cognitive techniques to understand how people really make moral decisions. Combining insights from the lab with lessons from decades of social science and centuries of philosophy, the great question of Moral Tribes is this: How can we get along with Them when what they want feels so wrong to Us? Ultimately, Greene offers a set of maxims for navigating the modern moral terrain, a practical road map for solving problems and living better lives. Moral Tribes shows us when to trust our instincts, when to reason, and how the right kind of reasoning can move us forward. A major achievement from a rising star in a new scientific field, Moral Tribes will refashion your deepest beliefs about how moral thinking works and how it can work better.

    It enabled us to migrate out of Africa and to spread as far as Alaska and Australia. Every day, we put one foot in front of the other―yet how many of us know how we do that, or appreciate the advantages it gives us?Neuroscientist Shane O’Mara invites us to marvel at the benefits walking confers on our bodies and brains. From walking’s evolutionary origins, traced back millions of years to life forms on the ocean floor, to new findings from cutting- edge research, he reveals how the brain and nervous system give us the ability to balance, weave through a crowded city, and run our “inner GPS” system. Walking, in turn, spurs our imaginations and boosts our moods. In Praise of Walking illuminates the joys, health benefits, and mechanics of walking―and reminds us to get out of our chairs and discover a happier, healthier, more creative self.

    She describes the "neurobiological platform of bonding" that, modified by evolutionary pressures and cultural values, has led to human styles of moral behavior. The result is a provocative genealogy of morals that asks us to reevaluate the priority given to religion, absolute rules, and pure reason in accounting for the basis of morality. Moral values, Churchland argues, are rooted in family values displayed by all mammals--the caring for offspring. The evolved structure, processes, and chemistry of the brain incline humans to strive not only for self-preservation but for the well-being of allied selves--first offspring, then mates, kin, and so on, in wider and wider "caring" circles. Separation and exclusion cause pain, and the company of loved ones causes pleasure; responding to feelings of social pain and pleasure, brains adjust their circuitry to local customs. In this way, caring is apportioned, conscience molded, and moral intuitions instilled. A key part of the story is oxytocin, an ancient body-and-brain molecule that, by decreasing the stress response, allows humans to develop the trust in one another necessary for the development of close-knit ties, social institutions, and morality. A major new account of what really makes us moral, Braintrust challenges us to reconsider the origins of some of our most cherished values.

    The PCs, the i- phones, the i-pods, the tablet PCs all will be a constant reminder of the genuine and witty ways that Steve handled and fondled. He was always lost in a world of his own. He hugged the glory and the downfalls with equal aloofness. Not once were his beliefs shattered. Throughout his life, he struggled and dared to bring his dreams come true. His dreams had a silvery lining of consistency, persuasion and intention. He was unique in every way. The life threatening disease of cancer could not prevent him from working till his last breath, literally. Though stubborn and dominant by nature he stood as a magician in the field of technology. Here is a simple gesture to pay him respect and honour. A magnificent journey presented authentically.

    Developing technology promises closeness. Sometimes it delivers, but much of our modern life leaves us less connected with people and more connected to simulations of them.In Alone Together, MIT technology and society professor Sherry Turkle explores the power of our new tools and toys to dramatically alter our social lives. It’s a nuanced exploration of what we are looking for—and sacrificing—in a world of electronic companions and social networking tools, and an argument that, despite the hand-waving of today’s self-described prophets of the future, it will be the next generation who will chart the path between isolation and connectivity.

    In this accessible introduction to philosophy of biology, Kim Sterelny and Paul E. Griffiths present both the science and the philosophical context necessary for a critical understanding of the most exciting debates shaping biology today. The authors, both of whom have published extensively in this field, describe the range of competing views—including their own—on these fascinating topics.With its clear explanations of both biological and philosophical concepts, Sex and Death will appeal not only to undergraduates, but also to the many general readers eager to think critically about the science of life.

    Yet underlying these subtle differences, Simon Baron-Cohen believes, there is one essential difference, and it affects everything we do: Men have a tendency to analyze and construct systems while women are inclined to empathize. With fresh evidence for these claims, Baron-Cohen explores how these sex differences arise more from biological than cultural causes and shows us how each brain type contributes in various ways to what we think of as "intelligence." Emphasizing that not all men have the typically "male" brain, which he calls Type "S," and not all women have the typically female brain (Type "E"), Baron-Cohen explores the cutting-edge research that illuminates our individual differences and explains why a truly "balanced" brain is so rare. Filled with surprising and illuminating case studies, many from Baron-Cohen's own clinical practice, The Essential Difference moves beyond the stereotypes to elucidate over twenty years of groundbreaking research. From gossip to aggression, Baron-Cohen dissects each brain type and even presents a new theory that autism (as well as its close relative, Asperger's syndrome) can be understood as an extreme form of the male brain. Smart and engaging, this is the thinking person's guide to gender difference, a book that promises to change the conversation about-and between-men and women.
