Most of the time this math works quietly behind the scenes . . . until it doesn't. All sorts of seemingly innocuous mathematical mistakes can have significant consequences.Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean.Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

    But in the inevitable condition of aging and death, the goals of medicine seem too frequently to run counter to the interest of the human spirit. Nursing homes, preoccupied with safety, pin patients into railed beds and wheelchairs. Hospitals isolate the dying, checking for vital signs long after the goals of cure have become moot. Doctors, committed to extending life, continue to carry out devastating procedures that in the end extend suffering.Gawande, a practicing surgeon, addresses his profession's ultimate limitation, arguing that quality of life is the desired goal for patients and families. Gawande offers examples of freer, more socially fulfilling models for assisting the infirm and dependent elderly, and he explores the varieties of hospice care to demonstrate that a person's last weeks or months may be rich and dignified.

    But what if our actions are driven not by our conscious values and beliefs but by hidden motivations we’re not even aware of?The “hidden brain” is Shankar Vedantam’s shorthand for a host of brain functions, emotional responses, and cognitive processes that happen outside our conscious awareness but have a decisive effect on how we behave. The hidden brain has its finger on the scale when we make all our most complex and important decisions: It decides whom we fall in love with, whether we should convict someone of murder, and which way to run when someone yells “Fire!” It explains why we can become riveted by the story of a single puppy adrift on the ocean but are quickly bored by a story of genocide. The hidden brain can also be deliberately manipulated to convince people to vote against their own interests, or even become suicide terrorists. But the most disturbing thing is that it does all this without our knowing.Shankar Vedantam, author of The Washington Post’s popular “Department of Human Behavior” column, takes us on a tour of this phenomenon and explores its consequences. Using original reporting that combines the latest scientific research with compulsively readable narratives that take readers from the American campaign trail to terrorist indoctrination camps, from the World Trade Center on 9/11 to, yes, a puppy adrift on the Pacific Ocean, Vedantam illuminates the dark recesses of our minds while making an original argument about how we can compensate for our blind spots and what happens when we don’t.

      We swim in freezing Arctic waters and piranha-infested rivers to test our limits. We swim for pleasure, for exercise, for healing. But humans, unlike other animals that are drawn to water, are not natural-born swimmers. We must be taught. Our evolutionary ancestors learned for survival; now, in the twenty-first century, swimming is one of the most popular activities in the world.Why We Swim is propelled by stories of Olympic champions, a Baghdad swim club that meets in Saddam Hussein’s palace pool, modern-day Japanese samurai swimmers, and even an Icelandic fisherman who improbably survives a wintry six-hour swim after a shipwreck. New York Times contributor Bonnie Tsui, a swimmer herself, dives into the deep, from the San Francisco Bay to the South China Sea, investigating what about water—despite its dangers—seduces us and why we come back to it again and again.

    A distinguished evolutionary biologist, Roughgarden takes on the medical establishment, the Bible, social science—and even Darwin himself. She leads the reader through a fascinating discussion of diversity in gender and sexuality among fish, reptiles, amphibians, birds, and mammals, including primates. Evolution's Rainbow explains how this diversity develops from the action of genes and hormones and how people come to differ from each other in all aspects of body and behavior. Roughgarden reconstructs primary science in light of feminist, gay, and transgender criticism and redefines our understanding of sex, gender, and sexuality. Witty, playful, and daring, this book will revolutionize our understanding of sexuality.Roughgarden argues that principal elements of Darwinian sexual selection theory are false and suggests a new theory that emphasizes social inclusion and control of access to resources and mating opportunity. She disputes a range of scientific and medical concepts, including Wilson's genetic determinism of behavior, evolutionary psychology, the existence of a gay gene, the role of parenting in determining gender identity, and Dawkins's "selfish gene" as the driver of natural selection. She dares social science to respect the agency and rationality of diverse people; shows that many cultures across the world and throughout history accommodate people we label today as lesbian, gay, and transgendered; and calls on the Christian religion to acknowledge the Bible's many passages endorsing diversity in gender and sexuality. Evolution's Rainbow concludes with bold recommendations for improving education in biology, psychology, and medicine; for democratizing genetic engineering and medical practice; and for building a public monument to affirm diversity as one of our nation's defining principles.

    Chanda Prescod-Weinstein shares her love for physics, from the Standard Model of Particle Physics and what lies beyond it, to the physics of melanin in skin, to the latest theories of dark matter — all with a new spin informed by history, politics, and the wisdom of Star Trek.One of the leading physicists of her generation, Dr. Chanda Prescod-Weinstein is also one of fewer than one hundred Black American women to earn a PhD from a department of physics. Her vision of the cosmos is vibrant, buoyantly non-traditional, and grounded in Black feminist traditions.Prescod-Weinstein urges us to recognize how science, like most fields, is rife with racism, sexism, and other dehumanizing systems. She lays out a bold new approach to science and society that begins with the belief that we all have a fundamental right to know and love the night sky. The Disordered Cosmos dreams into existence a world that allows everyone to tap into humanity’s wealth of knowledge about the wonders of the universe.

    In this provocative, unfailingly intelligent, thoroughly researched, and surprisingly convincing big idea book, Steven Johnson draws from fields as diverse as neuroscience, economics, and media theory to argue that the pop culture we soak in every day—from Lord of the Rings to Grand Theft Auto to The Simpsons—has been growing more sophisticated with each passing year, and, far from rotting our brains, is actually posing new cognitive challenges that are actually making our minds measurably sharper. After reading Everything Bad is Good for You, you will never regard the glow of the video game or television screen the same way again. With a new afterword by the author. Steven Johnson's newest book, How We Got to Now, is now available from Riverhead Books.

    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.

    For the first time in history, the secrets of the living brain are being revealed by a battery of high tech brain scans devised by physicists. Now what was once solely the province of science fiction has become a startling reality. Recording memories, telepathy, videotaping our dreams, mind control, avatars, and telekinesis are not only possible; they already exist. The Future of the Mind gives us an authoritative and compelling look at the astonishing research being done in top laboratories around the world—all based on the latest advancements in neuroscience and physics. One day we might have a "smart pill" that can enhance our cognition; be able to upload our brain to a computer, neuron for neuron; send thoughts and emotions around the world on a "brain-net"; control computers and robots with our mind; push the very limits of immortality; and perhaps even send our consciousness across the universe. Dr. Kaku takes us on a grand tour of what the future might hold, giving us not only a solid sense of how the brain functions but also how these technologies will change our daily lives. He even presents a radically new way to think about "consciousness" and applies it to provide fresh insight into mental illness, artificial intelligence and alien consciousness. With Dr. Kaku's deep understanding of modern science and keen eye for future developments, The Future of the Mind is a scientific tour de force--an extraordinary, mind-boggling exploration of the frontiers of neuroscience.

    In the space of a year, it's gone from something that most Americans had never heard of to a cause claiming the mantle of civil rights.But can a boy truly be "trapped" in a girl's body? Can modern medicine really "reassign" sex? Is sex something "assigned" in the first place? What's the loving response to a friend or child experiencing a gender-identity conflict? What should our law say on these issues?When Harry Became Sally: Responding to the Transgender Moment provides thoughtful answers to all of these questions. Drawing on the best insights from biology, psychology, and philosophy, Ryan T. Anderson offers a balanced approach to the policy issues, a nuanced vision of human embodiment, and a sober and honest survey of the human costs of getting human nature wrong.He reveals a grim contrast between the media's sunny depiction and the often sad realities of gender-identity struggles. He introduces readers to people who tried to "transition" but found themselves no better off. Especially troubling is the suffering felt by adults who were encouraged to transition as children but later came to regret it.And there is a reason that many do regret it. As Anderson shows, the most helpful therapies focus not on achieving the impossible--changing bodies to conform to thoughts and feelings--but on helping people accept and even embrace the truth about their bodies and reality. This discussion will be of particular interest to parents who fear how an ideological school counselor might try to steer their child. The best evidence shows that the vast majority of children naturally grow out of any gender-conflicted phase. But no one knows how new school policies might affect children indoctrinated to believe that they really are trapped in the "wrong" body.Throughout the book, Anderson highlights the various contradictions at the heart of this moment: How it embraces the gnostic idea that the real self is something other than the body, while also embracing the idea that nothing but the physical exists. How it relies on rigid sex stereotypes--in which dolls are for girls and trucks are for boys--while also insisting that gender is purely a social construct, and that there are no meaningful differences between women and men. How it assumes that feelings of identity deserve absolute respect, while the facts of our embodiment do not. How it preaches that people should be free to do as they please and define their own truth--while enforcing a ruthless campaign to coerce anyone who dares to dissent.Everyone has something at stake in today's debates about gender identity. Analyzing education and employment policies, Obama-era bathroom and locker-room mandates, politically correct speech codes and religious-freedom violations, Anderson shows how the law is being used to coerce and penalize those who believe the truth about human nature. And he shows how Americans can begin to push back with principle and prudence, compassion and grace.

    In the year 2018, it seems as if women’s anger has suddenly erupted into the public conversation. But long before Pantsuit Nation, before the Women’s March, and before the #MeToo movement, women’s anger was not only politically catalytic—but politically problematic. The story of female fury and its cultural significance demonstrates the long history of bitter resentment that has enshrouded women’s slow rise to political power in America, as well as the ways that anger is received when it comes from women as opposed to when it comes from men. With eloquence and fervor, Rebecca tracks the history of female anger as political fuel—from suffragettes marching on the White House to office workers vacating their buildings after Clarence Thomas was confirmed to the Supreme Court. Here Traister explores women’s anger at both men and other women; anger between ideological allies and foes; the varied ways anger is perceived based on its owner; as well as the history of caricaturing and delegitimizing female anger; and the way women’s collective fury has become transformative political fuel—as is most certainly occurring today. She deconstructs society’s (and the media’s) condemnation of female emotion (notably, rage) and the impact of their resulting repercussions. Highlighting a double standard perpetuated against women by all sexes, and its disastrous, stultifying effect, Traister’s latest is timely and crucial. It offers a glimpse into the galvanizing force of women’s collective anger, which, when harnessed, can change history.

    In this timely book, he leaves his adopted home of Denmark and embarks on a journey through all five of the Nordic countries to discover who these curious tribes are, the secrets of their success, and, most intriguing of all, what they think of one another.Why are the Danes so happy despite having the highest taxes? Do the Finns really have the best education system? Are the Icelanders as feral as they sometimes appear? How are the Norwegians spending their fantastic oil wealth? And why do all of them hate the Swedes? In The Almost Nearly Perfect People, Booth explains who the Scandinavians are, how they differ and why, and what their quirks and foibles are, and he explores why these societies have become so successful and models for the world. Along the way, a more nuanced, often darker picture emerges of a region plagued by taboos, characterized by suffocating parochialism, and populated by extremists of various shades.

    Unhappy people living in profoundly unstable states, he notes, inspire pathos and make for good copy, but not for good karma. So Weiner, admitted grump and self-help book aficionado, undertook a year's research to travel the globe, looking for the "unheralded happy places." The result is this book, equal parts laugh-out-loud funny and philosophical, a journey into both the definition of and the destination for true contentment.Apparently, the happiest places on earth include, somewhat unexpectedly, Iceland, Bhutan, and India. Weiner also visits the country deemed most malcontent, Moldova, and finds real merit in the claim.But the question remains: What makes people happy? Is it the freedom of the West or the myriad restrictions of Singapore? The simple ashrams of India or the glittering shopping malls of Qatar?From the youthful drunkenness of Iceland to the despond of Slough, a sad but resilient town in Heathrow's flight path, Weiner offers wry yet profound observations about the way people relate to circumstance and fate.Both revealing and inspirational, perhaps the best thing about this hilarious trip across four continents is that for the reader, the "geography of bliss" is wherever they happen to find themselves while reading it.
