From the very first attempts by the Greeks to grapple with the complexities of our known world to the latest application of infinity in physics, The Road to Reality carefully explores the movement of the smallest atomic particles and reaches into the vastness of intergalactic space. Here, Penrose examines the mathematical foundations of the physical universe, exposing the underlying beauty of physics and giving us one the most important works in modern science writing.

    In fact, a plethora of parasites affect our behavior in ways we have barely begun to understand.  In this mind-bending book, McAuliffe reveals the eons-old war between parasites and other creatures that is playing out in our very own bodies. And more surprising still, she uncovers the decisive role that parasites may have played in the rise and demise of entire civilizations. Our obsession with cleanliness and our experience of disgust are both evolutionary tools for avoiding infection, but they evolved differently for different populations. Political, social, and religious differences among societies may be caused, in part, by the different parasites that prey on us. In the tradition of Jared Diamond’s Guns, Germs, and Steel and Neil Shubin’s Your Inner Fish, This Is Your Brain on Parasites is both a journey into cutting-edge science and a revelatory examination of what it means to be human.

    These “psychosurgeons,” as they called themselves, occupied a gray zone between medical research and medical practice, and ended up subjecting untold numbers of people to the types of surgical experiments once limited to chimpanzees.The most important test subject to emerge from this largely untold chapter in American history was a twenty-seven-year-old factory worker named Henry Molaison. In 1953, Henry—who suffered from severe epilepsy—received a radical new version of the lobotomy, one that targeted the most mysterious structures in the brain. The operation failed to eliminate Henry’s seizures, but it did have an unintended effect: Henry left the operating room profoundly amnesic, unable to create new long-term memories. Over the next sixty years, Patient H.M., as Henry was known, became the most studied individual in the history of neuroscience, a human guinea pig who would teach us much of what we know about memory today.Luke Dittrich uses the case of Patient H.M. as a starting point for a kaleidoscopic journey, one that moves from the first recorded brain surgeries in ancient Egypt to the cutting-edge laboratories of MIT. He takes readers inside the old asylums and operating theaters where psychosurgeons conducted their human experiments, and behind the scenes of a bitter custody battle over the ownership of the most important brain in the world. Throughout, Dittrich delves into the enduring mysteries of the mind while exposing troubling stories of just how far we’ve gone in our pursuit of knowledge. It is also, at times, a deeply personal journey. Dittrich’s grandfather was the brilliant, morally complex surgeon who operated on Molaison—and thousands of other patients. The author’s investigation into the dark roots of modern memory science ultimately forces him to confront unsettling secrets in his own family history, and to reveal the tragedy that fueled his grandfather’s relentless experimentation—experimentation that would revolutionize our understanding of ourselves.Patient H.M. combines the best of biography, memoir, and science journalism to create a haunting, endlessly fascinating story, one that reveals the wondrous and devastating things that can happen when hubris, ambition, and human imperfection collide.

    According to revolutionary new research, some birds rival primates and even humans in their remarkable forms of intelligence. In The Genius of Birds, acclaimed author Jennifer Ackerman explores their newly discovered brilliance and how it came about. As she travels around the world to the most cutting-edge frontiers of research, Ackerman not only tells the story of the recently uncovered genius of birds but also delves deeply into the latest findings about the bird brain itself that are shifting our view of what it means to be intelligent. At once personal yet scientific, richly informative and beautifully written, The Genius of Birds celebrates the triumphs of these surprising and fiercely intelligent creatures.

    This fascinating collection of historical curiosities explores some of the strangest cases that have perplexed doctors across the world.From seventeenth-century Holland to Tsarist Russia, from rural Canada to a whaler in the Pacific, many are monuments to human stupidity – such as the sailor who swallowed dozens of penknives to amuse his shipmates, or the chemistry student who in 1850 arrived at a hospital in New York with his penis trapped inside a bottle, having unwisely decided to relieve himself into a vessel containing highly reactive potassium. Others demonstrate exceptional surgical ingenuity long before the advent of anaesthesia – such as a daring nineteenth-century operation to remove a metal fragment from beneath a conscious patient’s heart. We also hear of the weird, often hilarious remedies employed by physicians of yore – from crow’s vomit to port-wine enemas – the hazards of such everyday objects as cucumbers and false teeth, and miraculous recovery from apparently terminal injuries.

    In this far-reaching narrative, Weisman explains how our massive infrastructure would collapse and finally vanish without human presence; which everyday items may become immortalized as fossils; how copper pipes and wiring would be crushed into mere seams of reddish rock; why some of our earliest buildings might be the last architecture left; and how plastic, bronze sculpture, radio waves, and some man-made molecules may be our most lasting gifts to the universe.The World Without Us reveals how, just days after humans disappear, floods in New York's subways would start eroding the city's foundations, and how, as the world's cities crumble, asphalt jungles would give way to real ones. It describes the distinct ways that organic and chemically treated farms would revert to wild, how billions more birds would flourish, and how cockroaches in unheated cities would perish without us. Drawing on the expertise of engineers, atmospheric scientists, art conservators, zoologists, oil refiners, marine biologists, astrophysicists, religious leaders from rabbis to the Dalai Lama, and paleontologists—who describe a prehuman world inhabited by megafauna like giant sloths that stood taller than mammoths—Weisman illustrates what the planet might be like today, if not for us.From places already devoid of humans (a last fragment of primeval European forest; the Korean DMZ; Chernobyl), Weisman reveals Earth's tremendous capacity for self-healing. As he shows which human devastations are indelible, and which examples of our highest art and culture would endure longest, Weisman's narrative ultimately drives toward a radical but persuasive solution that needn't depend on our demise. It is narrative nonfiction at its finest, and in posing an irresistible concept with both gravity and a highly readable touch, it looks deeply at our effects on the planet in a way that no other book has.

    Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But after a half century of scanning the skies, astronomers have little to report but an eerie silence—eerie because many scientists are convinced that the universe is teeming with life. The problem, argues the leading physicist-astrobiologist Paul Davies, is that we’ve been looking in the wrong place, at the wrong time & in the wrong way. Davies should know. For more than three decades, he's been closely involved with SETI & now chairs its Post-Detection Taskgroup, charged with deciding what to do if we’re confronted with evidence of alien intelligence. In this extraordinary book, he shows how SETI has lost its edge & offers a new exciting road map for the future. Davies believes our search so far has been overly anthropocentric: we tend to assume an alien species will look, think & behave like us. He argues that we need to be far more expansive in our efforts, & in this book he completely redefines the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us & how we should respond if it does. A provocative & mind-expanding journey, The Eerie Silence will thrill fans of science & science fiction alike.

    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.

    In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions--clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips--and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer. She describes, among other things, how our pursuit of precision in timepieces changed how we sleep; how the railroad helped commercialize Christmas; how the necessary brevity of the telegram influenced Hemingway's writing style; and how a young chemist exposed the use of Polaroid's cameras to create passbooks to track black citizens in apartheid South Africa. These fascinating and inspiring stories offer new perspectives on our relationships with technologies.Ramirez shows how materials were shaped by inventors, but also how those materials shaped culture, chronicling each invention and its consequences--intended and unintended. Filling in the gaps left by other books about technology, Ramirez showcases little-known inventors--particularly people of color and women--who had a significant impact but whose accomplishments have been hidden by mythmaking, bias, and convention. Doing so, she shows us the power of telling inclusive stories about technology. She also shows that innovation is universal--whether it's splicing beats with two turntables and a microphone or splicing genes with two test tubes and CRISPR.

    But in Catching Fire, renowned primatologist Richard Wrangham presents a startling alternative: our evolutionary success is the result of cooking. In a groundbreaking theory of our origins, Wrangham shows that the shift from raw to cooked foods was the key factor in human evolution. when our ancestors adapted to using fire, humanity began.Once our hominid ancestors began cooking their food, the human digestive tract shrank and the brain grew. Time once spent chewing tough raw food could be used instead to hunt and to tend camp. Cooking became the basis for pair bonding and marriage, created the household, and even led to a sexual division of labor.Tracing the contemporary implications of our ancestors' diets, Catching Fire sheds new light on how we came to be the social, intelligent, and sexual species we are today. A pathbreaking new theory of human evolution, Catching Fire will provoke controversy and fascinate anyone interested in our ancient origins--or in our modern eating habits.--from the dustjacket

    “There is a fix,” Acho says. “But in order to access it, we’re going to have to have some uncomfortable conversations.”In Uncomfortable Conversations With a Black Man, Acho takes on all the questions, large and small, insensitive and taboo, many white Americans are afraid to ask—yet which all Americans need the answers to, now more than ever. With the same open-hearted generosity that has made his video series a phenomenon, Acho explains the vital core of such fraught concepts as white privilege, cultural appropriation, and “reverse racism.”In his own words, he provides a space of compassion and understanding in a discussion that can lack both. He asks only for the reader’s curiosity—but along the way, he will galvanize all of us to join the antiracist fight.

    In so doing, he reaches a provocative conclusion: science, the main tool we use to find answers, is fundamentally limited.These limits to our knowledge arise both from our tools of exploration and from the nature of physical reality: the speed of light, the uncertainty principle, the impossibility of seeing beyond the cosmic horizon, the incompleteness theorem, and our own limitations as an intelligent species. Recognizing limits in this way, Gleiser argues, is not a deterrent to progress or a surrendering to religion. Rather, it frees us to question the meaning and nature of the universe while affirming the central role of life and ourselves in it. Science can and must go on, but recognizing its limits reveals its true mission: to know the universe is to know ourselves.Telling the dramatic story of our quest for understanding, The Island of Knowledge offers a highly original exploration of the ideas of some of the greatest thinkers in history, from Plato to Einstein, and how they affect us today. An authoritative, broad-ranging intellectual history of our search for knowledge and meaning, The Island of Knowledge is a unique view of what it means to be human in a universe filled with mystery.

    Today there is just one. Us. Homo sapiens. How did our species succeed in the battle for dominance? Why did our foraging ancestors come together to create cities and kingdoms? How did we come to believe in gods, nations and human rights; to trust money, books and laws; and to be enslaved by bureaucracy, timetables and consumerism? And what will our world be like in the millennia to come? In Sapiens, Dr Yuval Noah Harari spans the whole of human history, from the very first humans to walk the earth to the radical – and sometimes devastating – breakthroughs of the Cognitive, Agricultural and Scientific Revolutions. Drawing on insights from biology, anthropology, paleontology and economics, he explores how the currents of history have shaped our human societies, the animals and plants around us, and even our personalities. Have we become happier as history has unfolded? Can we ever free our behaviour from the heritage of our ancestors? And what, if anything, can we do to influence the course of the centuries to come? Bold, wide-ranging and provocative, Sapiens challenges everything we thought we knew about being human: our thoughts, our actions, our power ... and our future.

    Gut, an international bestseller, gives the alimentary canal its long-overdue moment in the spotlight. With quirky charm, rising science star Giulia Enders explains the gut’s magic, answering questions like: Why does acid reflux happen? What’s really up with gluten and lactose intolerance? How does the gut affect obesity and mood? Communication between the gut and the brain is one of the fastest-growing areas of medical research—on par with stem-cell research. Our gut reactions, we learn, are intimately connected with our physical and mental well-being. Enders’s beguiling manifesto will make you finally listen to those butterflies in your stomach: they’re trying to tell you something important.

    The epidemics of obesity, heart disease, and diabetes are not tied to the overabundance of fat or carbs or any other specific nutrient. Instead, we have been led astray by the growing divide between flavor - the tastes we crave - and the underlying nutrition. Since the late 1940s, we have been slowly leeching flavor out of the food we grow. Those perfectly round, red tomatoes that grace our supermarket aisles today are mostly water, and the big breasted chickens on our dinner plates grow three times faster than they used to, leaving them dry and tasteless. Simultaneously, we have taken great leaps forward in technology, allowing us to produce in the lab the very flavors that are being lost on the farm. Thanks to this largely invisible epidemic, seemingly healthy food is becoming more like junk food: highly craveable but nutritionally empty. We have unknowingly interfered with an ancient chemical language - flavor - that evolved to guide our nutrition, not destroy it.With in-depth historical and scientific research, The Dorito Effect casts the food crisis in a fascinating new light, weaving an enthralling tale of how we got to this point and where we are headed. We've been telling ourselves that our addiction to flavor is the problem, but it is actually the solution. We are on the cusp of a new revolution in agriculture that will allow us to eat healthier and live longer by enjoying flavor the way nature intended.
