Weaving together the cosmos' history and our own in an expanding intellectual adventure story, Dark Matter and the Dinosaurs takes us from the mysteries of dark matter and our cosmic environment to the conditions for life on Earth.Sixty-six million years ago, an object the size of a city descended from space to crash into Earth, creating a cataclysm that killed off the dinosaurs, along with three-quarters of the other species on the planet. What was its origin? Randall proposes it was a comet that was dislodged from its orbit as the Solar System passed through a disk of dark matter that is embedded in the plane of the Milky Way. Her research challenges the usual assumptions about the simple nature of dark matter and demonstrates how scientists formulate and establish new ideas. In a sense, it might have been dark matter that killed the dinosaurs.With her unique and wide-ranging perspective, Randall connects dark matter to the history of the world in the broadest terms. Bringing in pop culture and social and political viewpoints, she shares with us the latest findings—established and speculative—regarding dark matter, the cosmos, the galaxy, asteroids, comets, and impacts, as well as life's development and extinctions. Randall makes clear how connected the planet is to the makeup of the Universe, but also how fragile our place in the Universe, which evolved over billions of years, might be.In this brilliant and fresh exploration of our cosmic environment, Professor Randall explains the underlying science of our world in the breathtaking tale of a Universe in which the small and the large, the visible and the hidden are intimately related. Dark Matter and the Dinosaurs illuminates the deep relationships that are critical to our world as well as the astonishing beauty of the structures and connections that surround us. It's impossible to read this book and look at either Earth or sky again in the same way.

    Set in almost uninhabitable regions of Central Australia, The Songlines asks and tries to answer these questions: Why is man the most restless, dissatisfied of animals? Why do wandering people conceive the world as perfect whereas sedentary ones always try to change it? Why have the great teachers—Christ or the Buddha—recommended the Road as the way. to salvation? Do we agree with Pascal that all man's troubles stem from his inability to sit quietly in a room?We do not often ask these questions today for we commonly assume that living in a house is normal and that the wandering life is aberrant. But for more than twenty years Chatwin has mulled over the possibility that the reverse might be the case.Pre-colonial Australia was the last landmass on earth peopled not by herdsmen, farmers, or city dwellers, but by hunter-gatherers. Their labyrinths of invisible pathways across the continent are known to us as Songlines or Dreaming Tracks, but to the Aboriginals as the tracks of their ancestors—the Way of the Law. Along these "roads" they travel in order to perform all those activities that are distinctively human—song, dance, marriage, exchange of ideas, and arrangements of territorial boundaries by agreement rather than force.In Chatwin's search for the Songlines, Arkady is an ideal friend and guide: Australian by birth, the son of a Cossack exile, with all the strength and warmth of his inheritance. Whether hunting kangaroo from a Land Cruiser, talking to the diminutive Rolf in his book-crammed trailer, buying drinks for a bigoted policeman (and would-be writer), cheering as Arkady's true love declares herself (part of The Songlines is a romantic comedy), Chatwin turns this almost implausible picaresque adventure into something approaching the scale of a Greek tragedy.The life of the Aboriginals stands in vivid contrast, of course, to the prevailing cultures of our time. And The Songlines presents unforgettable details about the kinds of disputes we know all too well from less traumatic confrontations: over sacred lands invaded by railroads, mines, and construction sites, over the laws and rights of a poor people versus a wealthy invasive one. To Chatwin these are but recent, local examples of an eternal basic distinction between settlers and wanderers. His book, devoted to the latter, is a brilliant evocation of this profound optimism: that man is by nature not a bellicose aggressor but a pacific, song-creating, adaptive species whose destiny is to quest for the truth.

    Comparing gene sequences, examining atomic structures of proteins, and looking into the geochemistry of rocks have helped explain evolution in more detail than ever before. Nick Lane expertly reconstructs the history of life by describing the ten greatest inventions of evolution (including DNA, photosynthesis, sex, and sight), based on their historical impact, role in organisms today, and relevance to current controversies. Who would have guessed that eyes started off as light-sensitive spots used to calibrate photosynthesis in algae? Or that DNA’s building blocks form spontaneously in hydrothermal vents? Lane gives a gripping, lucid account of nature’s ingenuity, and the result is a work of essential reading for anyone who has ever pondered or questioned the science underlying evolution’s greatest gifts to man.

    Reay Tannahill's scholarly, yet accessible study ranges from the earliest form of contraception (one Egyptian concoction included crocodile dung) to some latter- day misconceptions about it- like the men who joined their lovers in taking the pill 'just to be on the safe side.' It surveys all manner of sexual practice, preference and position (the acrobatic 'wheelbarrow' position, the strenuous 'hovering butterflies' position...) and draws on souces as diverse as THE ADMIRABLE DISCOURSES OF THE PLAIN GIRL, the EXHIBTION OF FEMALE FLAGELLANTS, IMPORTANT MATTERS OF THE JADE CHAMBER and THE ROMANCE OF CHASTISEMENT. Whether writing on androgyny, courtly love, flagellation or zoophilia, Turkish eunuch's Greek dildoes, Taoist sex manuals or Japanses geisha girls, Reay Tannahill is consistently enlightening and entertaining.

    Professor Douglas makes points which illuminate matters in the philosophy of religion and the philosophy of science and help to show the rest of us just why and how anthropology has become a fundamentally intellectual discipline.

    In his delightfully down-to-earth style, he explores & explains a mind-boggling future of intelligent robots, extraterrestrial life & its consquences, & other provocative, fascinating quandries of the future we want to see today.

    It's what you have if you're a politician and you've strayed from your wife, and it's why five times as many Americans undergo plastic surgery and cosmetic procedures today than did just ten years ago. It's the value that parents teach their children with song lyrics like "I am special. Look at me," the skill teenagers and young adults obsessively hone on Facebook and MySpace, and the reason high school students physically beat classmates and then broadcast their violence on YouTube for all to see. It's the message preached by prosperity gospel and the vacuous ethos spread by celebrity newsmakers. And it's what's making people depressed, lonely, and buried under piles of debt.Jean M. Twenge's influential and controversial first book, Generation Me, generated a national debate with its trenchant depiction of the challenges twenty- and thirtysomethings face emotionally and professionally in today's world -- and the fallout these issues create for older generations as well as employers. Now, Dr. Twenge is on to a new incendiary topic that has repercussions for every age-group and class: the pernicious spread of narcissism in today's culture and its catastrophic effects. Dr. Twenge joins forces with W. Keith Campbell, Ph.D., a nationally recognized expert on narcissism, for The Narcissism Epidemic, their eye-opening exposition of the alarming rise of narcissism -- and they show how to stop it.Every day, you encounter the real costs of narcissism: in your relationships and family, in the workplace and the economy at large, in schools that fail to teach necessary skills, in culture, and in politics. Even the world economy has been damaged by risky, unrealistic overconfidence. Filled with arresting anecdotes that illustrate the hold narcissism has on us today -- from people hiring fake paparazzi in order to experience feeling famous to college students who won't leave a professor's office until their B+ becomes an A -- The Narcissism Epidemic is at once a riveting window into the consequences of narcissism, a probing analysis of the culture at large, and a prescription to combat the widespread problems caused by narcissism. As a society, we have a chance to slow the epidemic of narcissism once we learn to identify it, minimize the forces that sustain and transmit it, and treat it where we find it. Drawing on their own extensive research as well as decades of other experts' studies, Drs. Twenge and Campbell show us how.

    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.

    Etcoff, a faculty member at Harvard Medical School and a practicing psychologist at Massachusetts General Hospital, skewers the enduring myth that the pursuit of beauty is a learned behavior.Etcoff puts forth that beauty is neither a cultural construction, an invention of the fashion industry, nor a backlash against feminism, but instead is in our biology. It's an essential and ineradicable part of human nature that is revered and ferociously pursued in nearly every civilizatoin--and for good reason. Those features to which we are most attracted are often signals of fertility and fecundity. When seen in the context of a Darwinian struggle for survival, our sometimes extreme attempts to attain beauty--both to become beautiful ourselves and to acquire an attractive partner--become understandable. Moreover, if we come to understand how the desire for beauty is innate, then we can begin to work in our interests, and not soley for the interests of our genetic tendencies.

    Nature’s many innovations—some uncannily perfect—call for natural principles that accelerate life’s ability to innovate.”Darwin’s theory of natural selection explains how useful adaptations are preserved over time. But the biggest mystery about evolution eluded him. As genetics pioneer Hugo de Vries put it, “natural selection may explain the survival of the fittest, but it cannot explain the arrival of the fittest.”Can random mutations over a mere 3.8 billion years really be responsible for wings, eyeballs, knees, camouflage, lactose digestion, photosynthesis, and the rest of nature’s creative marvels? And if the answer is no, what is the mechanism that explains evolution’s speed and efficiency?In Arrival of the Fittest, renowned evolutionary biologist Andreas Wagner draws on over fifteen years of research to present the missing piece in Darwin's theory. Using experimental and computational technologies that were heretofore unimagined, he has found that adaptations are not just driven by chance, but by a set of laws that allow nature to discover new molecules and mechanisms in a fraction of the time that random variation would take.Consider the Arctic cod, a fish that lives and thrives within six degrees of the North Pole, in waters that regularly fall below 0 degrees. At that temperature, the internal fluids of most organisms turn into ice crystals. And yet, the arctic cod survives by producing proteins that lower the freezing temperature of its body fluids, much like antifreeze does for a car’s engine coolant. The invention of those proteins is an archetypal example of nature’s enormous powers of creativity. Meticulously researched, carefully argued, evocatively written, and full of fascinating examples from the animal kingdom, Arrival of the Fittest offers up the final puzzle piece in the mystery of life’s rich diversity.

    Feynman's contributions to twentieth-century physics, but few realize how engaged he was with the world around him -- how deeply and thoughtfully he considered the religious, political, and social issues of his day. Now, a wonderful book -- based on a previously unpublished, three-part public lecture he gave at the University of Washington in 1963 -- shows us this other side of Feynman, as he expounds on the inherent conflict between science and religion, people's distrust of politicians, and our universal fascination with flying saucers, faith healing, and mental telepathy. Here we see Feynman in top form: nearly bursting into a Navajo war chant, then pressing for an overhaul of the English language (if you want to know why Johnny can't read, just look at the spelling of "friend"); and, finally, ruminating on the death of his first wife from tuberculosis. This is quintessential Feynman -- reflective, amusing, and ever enlightening.

    Our rules for living are more like the history of pop songs. They make weird sense only to the people of each given time period. They aren't true. This book shows you how past myths functioned, and likewise how our myths of today function, and thus lets you out of the trap of thinking you have to pay heed to any of them."The Happiness Myth is a fascinating cultural history that both reveals our often silly assumptions about how we pursue happiness today and offers up real historical lessons that have stood the test of time. Hecht delivers memorable insights into the five practical means we choose to achieve happiness: wisdom, drugs, money, bodies, and celebration.Hecht liberates us from today's scolding, quasi-scientific messages that insist there is only one way to care for our minds and bodies. Hecht looks at contemporary happiness advice and explains why much of it doesn't work. "Modern culture," she writes, "is misrepresenting me and spending a lot of money to do it."Rich with hilarious anecdotes about both failed and successful paths to happiness, Hecht's book traces a common thread of advice—she calls it "sour charm wisdom"—that we can still apply today to create authentic, lasting happiness.

    In Quirkology, he navigates the backwaters of human behavior, discovering the tell-tale signs that give away a liar, the secret science behind speed-dating and personal ads, and what a person's sense of humor reveals about the innermost workings of their mind- all along paying tribute to others who have carried out similarly weird and wonderful work. Wiseman's research has involved secretly observing people as they go about their daily business, conducting unusual experiments in art exhibitions and music concerts, and even staging fake seances in allegedly haunted buildings. With thousands of research subjects from all over the world, including enamored couples, unwitting pedestrians, and guileless dinner guests, Wiseman presents a fun, clever, and unexpected picture of the human mind.

    We're all conspiracy theorists--some of us just hide it better than others.Conspiracy theorists aren't just a handful of people who wear tin-foil hats and have bizarre ideas about shape-shifting reptilian aliens. Conspiracy theories are as likely to appeal to women as to men, college students as to retired professors, middle-class bloggers as to blue-collar workers.Psychological research sheds light on why some people are more drawn to conspiracy thinking, especially when they feel discontented, distrustful, and desire privileged knowledge. But ultimately we are all natural-born conspiracy theorists. Our brains are wired to see patterns and to weave unrelated data points into complex stories. We instinctively see events in the world in terms of human motives and intentions, leading us to discount the role of chance and unintended consequences, and we look for some hidden hand behind catastrophic events. These psychological quirks can lead us to suspect a conspiracy where none exists.Conspiracy theories have existed throughout history, from ancient Athens and Rome to present day theories about 9/11 and who shot JFK. Suspicious Minds explores the phenomenon and reveals the important consequences conspiracy theories can have--from discouraging parents from vaccinating their children against deadly diseases to hampering political policies to combat climate change.
