    But what if, nonetheless, Einstein got it wrong?Since the 1930s, physicists have noticed an alarming discrepancy between the universe as we see it and the universe that Einstein's theory of relativity predicts. There just doesn't seem to be enough stuff out there for everything to hang together. Galaxies spin so fast that, based on the amount of visible matter in them, they ought to be flung to pieces, the same way a spinning yo-yo can break its string. Cosmologists tried to solve the problem by positing dark matter—a mysterious, invisible substance that surrounds galaxies, holding the visible matter in place—and particle physicists, attempting to identify the nature of the stuff, have undertaken a slew of experiments to detect it. So far, none have.Now, John W. Moffat, a physicist at the Perimeter Institute for Theoretical Physics in Waterloo, Canada, offers a different solution to the problem. The cap­stone to a storybook career—one that began with a correspondence with Einstein and a conversation with Niels Bohr—Moffat's modified gravity theory, or MOG, can model the movements of the universe without recourse to dark matter, and his work chal­lenging the constancy of the speed of light raises a stark challenge to the usual models of the first half-million years of the universe's existence.This bold new work, presenting the entirety of Moffat's hypothesis to a general readership for the first time, promises to overturn everything we thought we knew about the origins and evolution of the universe.

    However, because it leaves no permanent trace, its evolution has long been a mystery, and it is only in the last fifteen years that we have begun to understand how language came into being. "The First Word" is the compelling story of the quest for the origins of human language. The book follows two intertwined narratives. The first is an account of how language developed?how the random and layered processes of evolution wound together to produce a talking animal: us. The second addresses why scientists are at last able to explore the subject. For more than a hundred years, language evolution was considered a scientific taboo. Kenneally focuses on figures like Noam Chomsky and Steven Pinker, along with cognitive scientists, biologists, geneticists, and animal researchers, in order to answer the fundamental question: Is language a uniquely human phenomenon? "The First Word" is the first book of its kind written for a general audience. Sure to appeal to fans of Steven Pinker's "The Language Instinct" and Jared Diamond's "Guns, Germs, and Steel," Kenneally's book is set to join them as a seminal account of human history.

    The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    The sixteenth and seventeenth centuries witnessed the Copernican Revolution, which bodychecked the Earth as the pivot point of creation and joined us with the rest of the cosmos as one planet among many orbiting the Sun. Three centuries later came the second great scientific revolution: the Darwinian Revolution. It removed us from a distinct, divine biological status to place us wholly in the ebb and flow of all terrestrial life. This book describes how we’re in the midst of a third great scientific revolution, five centuries in the making: the Stardust Revolution. It is the merging of the once-disparate realms of astronomy and evolutionary biology, and of the Copernican and Darwinian Revolutions, placing life in a cosmic context. This book takes readers on a grand journey that begins on the summit of California’s Mount Wilson, where astronomers first realized that the universe is both expanding and evolving, to a radio telescope used to identify how organic molecules—the building blocks of life—are made by stars. It’s an epic story told through a scientific cast that includes some of the twentieth century’s greatest minds—including Nobel laureate Charles Townes, who discovered cosmic water—as well as the most ambitious scientific explorers of the twenty-first century, those racing to find another living planet. Today, an entirely new breed of scientists—astrobiologists and astrochemists—are taking the study of life into the space age. Astrobiologists study the origins, evolution, and distribution of life, not just on Earth, but in the universe. Stardust science is filling in the missing links in our evolutionary story, ones that extend our family tree back to the stars.

    Drawing on evidence from archaeology, history, cognitive neuroscience, psychopharmacology, social psychology, literature, and genetics, Slingerland shows that our taste for chemical intoxicants is not an evolutionary mistake, as we are so often told. In fact, intoxication helps solve a number of distinctively human challenges: enhancing creativity, alleviating stress, building trust, and pulling off the miracle of getting fiercely tribal primates to cooperate with strangers. Our desire to get drunk, along with the individual and social benefits provided by drunkenness, played a crucial role in sparking the rise of the first large-scale societies. We would not have civilization without intoxication. From marauding Vikings and bacchanalian orgies to sex-starved fruit flies, blind cave fish, and problem-solving crows, Drunk is packed with fascinating case studies and engaging science, as well as practical takeaways for individuals and communities. The result is a captivating and long overdue investigation into humanity's oldest indulgence—one that explains not only why we want to get drunk, but also how it might actually be good for us to tie one on now and then.

    Someday, we know, we will all die. And, we know, so too will the universe itself.Until the End of Time is Brian Greene's breathtaking new exploration of the cosmos and our quest to understand it. Greene takes us on a journey across time, from our most refined understanding of the universe's beginning, to the closest science can take us to the very end. He explores how life and mind emerged from the initial chaos, and how our minds, in coming to understand their own impermanence, seek in different ways to give meaning to experience: in story, myth, religion, creative expression, science, the quest for truth, and our longing for the timeless, or eternal. Through a series of nested stories that explain distinct but interwoven layers of reality-from the quantum mechanics to consciousness to black holes-Greene provides us with a clearer sense of how we came to be, a finer picture of where we are now, and a firmer understanding of where we are headed.Yet all this understanding, which arose with the emergence of life, will dissolve with its conclusion. Which leaves us with one realization: during our brief moment in the sun, we are tasked with the charge of finding our own meaning.Let us embark.

    In doing so, the authors synthesize information from astronomy, biology, and paleontology, and apply it to what we know about the rise of life on Earth and to what could possibly happen elsewhere in the universe. Everyone who has been thrilled by the recent discoveries of extrasolar planets and the indications of life on Mars and the Jovian moon Europa will be fascinated by Rare Earth, and its implications for those who look to the heavens for companionship.

    Khushwant Singh tells the story of the land and its people from the earliest time to the present day. In broad, vivid sweeps he encapsulates the saga of the upheavals of a sub-continent over five millennia, and how their interplay over the centuries has molded the India of today. More, Khushwant Singh offers perceptive insights into everything Indian that may catch one's eye or arouse curiosity: its ethnic diversity, religions, customs, philosophy, art and culture, political currents, and the galaxy of men and women who have helped shape its intricately inlaid mosaic. He is also an enlightening guide to much else: India's extensive and varied architectural splendors, its art and classical literature. Khushwant Singh's own fascination with the subject is contagious, showing through on every page, and in every sidelight that he recounts. India: An Introduction holds strong appeal for just about anyone who has more than a passing interest in the country, Indians as well as those who are drawn to it from farther afield. And for a traveller, it is that rare companion: erudite, intelligent, lively

    Now, in The Great Wave, Fischer has done it again, marshaling an astonishing array of historical facts in lucid and compelling prose to outline a history of prices--"the history of change," as Fischer puts it--covering the dazzling sweep of Western history from the medieval glory of Chartres to the modern day. Going far beyond the economic data, Fischer writes a powerful history of the people of the Western world: the economic patterns they lived in, and the politics, culture, and society that they created as a result. As he did in Albion's Seed and Paul Revere's Ride, two of the most talked-about history books in recent years, Fischer combines extensive research and meticulous scholarship with wonderfully evocative writing to create a book for scholars and general readers alike.Records of prices are more abundant than any other quantifiable data, and span the entire range of history, from tables of medieval grain prices to the overabundance of modern statistics. Fischer studies this wealth of data, creating a narrative that encompasses all of Western culture. He describes four waves of price revolutions, each beginning in a period of equilibrium: the High Middle Ages, the Renaissance, the Enlightenment, and finally the Victorian Age. Each revolution is marked by continuing inflation, a widening gap between rich and poor, increasing instability, and finally a crisis at the crest of the wave that is characterized by demographic contraction, social and political upheaval, and economic collapse. The most violent of these climaxes was the catastrophic fourteenth century, in which war, famine, and the Black Death devastated the continent--the only time in Europe's history that the population actually declined.Fischer also brilliantly illuminates how these long economic waves are closely intertwined with social and political events, affecting the very mindset of the people caught in them. The long periods of equilibrium are marked by cultural and intellectual movements--such as the Renaissance, the Enlightenment, and the Victorian Age-- based on a belief in order and harmony and in the triumph of progress and reason. By contrast, the years of price revolution created a melancholy culture of despair.Fischer suggests that we are living now in the last stages of a price revolution that has been building since the turn of the century. The destabilizing price surges and declines and the diminished expectations the United States has suffered in recent years--and the famines and wars of other areas of the globe--are typical of the crest of a price revolution. He does not attempt to predict what will happen, noting that "uncertainty about the future is an inexorable fact of our condition." Rather, he ends with a brilliant analysis of where we might go from here and what our choices are now. This book is essential reading for anyone concerned about the state of the world today.

    Indeed, for the last fifty years, most popular and scholarly works have agreed that prehistoric warfare was rare, harmless, unimportant, and, like smallpox, a disease of civilized societies alone. Prehistoric warfare, according to this view, was little more than a ritualized game, where casualties were limited and the effects of aggression relatively mild. Lawrence Keeley's groundbreaking War Before Civilization offers a devastating rebuttal to such comfortable myths and debunks the notion that warfare was introduced to primitive societies through contact with civilization (an idea he denounces as the pacification of the past). Building on much fascinating archeological and historical research and offering an astute comparison of warfare in civilized and prehistoric societies, from modern European states to the Plains Indians of North America, War Before Civilization convincingly demonstrates that prehistoric warfare was in fact more deadly, more frequent, and more ruthless than modern war. To support this point, Keeley provides a wide-ranging look at warfare and brutality in the prehistoric world. He reveals, for instance, that prehistorical tactics favoring raids and ambushes, as opposed to formal battles, often yielded a high death-rate; that adult males falling into the hands of their enemies were almost universally killed; and that surprise raids seldom spared even women and children. Keeley cites evidence of ancient massacres in many areas of the world, including the discovery in South Dakota of a prehistoric mass grave containing the remains of over 500 scalped and mutilated men, women, and children (a slaughter that took place a century and a half before the arrival of Columbus). In addition, Keeley surveys the prevalence of looting, destruction, and trophy-taking in all kinds of warfare and again finds little moral distinction between ancient warriors and civilized armies. Finally, and perhaps most controversially, he examines the evidence of cannibalism among some preliterate peoples. Keeley is a seasoned writer and his book is packed with vivid, eye-opening details (for instance, that the homicide rate of prehistoric Illinois villagers may have exceeded that of the modern United States by some 70 times). But he also goes beyond grisly facts to address the larger moral and philosophical issues raised by his work. What are the causes of war? Are human beings inherently violent? How can we ensure peace in our own time? Challenging some of our most dearly held beliefs, Keeley's conclusions are bound to stir controversy.

    This brief introduction shows how psycholinguistic research can act as a window to the workings of the human mind and the study of consciousness.

    Such anomalous evidence, contradicting Darwinian evolution, catalyzed a global inquiry: “If we did not evolve from apes then where did we come from?”Human Devolution is Michael A. Cremo’s definitive answer to that question: “We did not evolve up from matter; instead we devolved, or came down, from the realm of pure consciousness, spirit.” Basing his response on modern science and the world’s great wisdom traditions, including the Vedic philosophy of ancient India, Cremo proposes that before we ask the question, “Where did human beings come from?” we should first contemplate, “What is a human being?” For much of the twentieth century, most scientists assumed that a human being is simply a combination of ordinary physical elements. In Human Devolution, Cremo says it is more reasonable to assume that a human being is a combination of three distinct substances: matter, mind, and consciousness (or spirit). He shows how solid scientific evidence for a subtle mind element and a conscious self that can exist apart from the body has been systematically eliminated from mainstream science by a process of “knowledge filtration.”

    Moffett draws on findings in psychology, sociology and anthropology to explain the social adaptations that bind societies. He explores how the tension between identity and anonymity defines how societies develop, function, and fail.
