It is the root of our existence, supporting our feet, our farms, our cities. This fascinating yet disquieting book finds, however, that we are running out of dirt, and it's no laughing matter. An engaging natural and cultural history of soil that sweeps from ancient civilizations to modern times, Dirt: The Erosion of Civilizations explores the compelling idea that we are—and have long been—using up Earth's soil. Once bare of protective vegetation and exposed to wind and rain, cultivated soils erode bit by bit, slowly enough to be ignored in a single lifetime but fast enough over centuries to limit the lifespan of civilizations. A rich mix of history, archaeology and geology, Dirt traces the role of soil use and abuse in the history of Mesopotamia, Ancient Greece, the Roman Empire, China, European colonialism, Central America, and the American push westward. We see how soil has shaped us and we have shaped soil—as society after society has risen, prospered, and plowed through a natural endowment of fertile dirt. David R. Montgomery sees in the recent rise of organic and no-till farming the hope for a new agricultural revolution that might help us avoid the fate of previous civilizations.

    And like it or not, it’s one of the most important things you do on a daily basis. Successful conversationshelp you advance professionally and make, maintain, and deepen relationships. Moreover, research shows that talking, when done on a substantive level, is correlated with a feeling of happiness and general well-being.Being a great conversationalist requires practice and effort. The good news is it’s a skill set anyone can acquire and refine. In just six lectures, How Conversation Works: 6 Lessons for Better Communication will teach you key strategies that can dramatically improve your ability to converse with anyone, from strangers to supervisors. Delivered by award-winning English professor Anne Curzan of the University of Michigan, this highly practical course focuses on the fundamental principles you need to know to become more conversationally aware and savvy at home, in the workplace, and beyond.You’ll be amazed by how much you can learn by stepping back from conversations and examining how they operate. You’ll notice things you never picked up on before—like what kind of speaker you are, the strategies you typically rely on (often without realizing it), and the subtleties of the strategies others may use when speaking with you. You’ll find yourself putting these lessons into practice to create more effective dialogues from the very first lecture.Choose Your Words WiselyAn expression like “shooting the breeze” makes conversation sound easy and free-flowing, but even low-stakes conversations have an underlying systematic structure that propels them along. This course examines that framework while showing you how the effective selection of words can help you forge connections and accomplish your objectives.Professor Curzan walks you through techniques for negotiating a variety of difficult situations, from proffering successful apologies to engaging in “face-threatening acts”—those uncomfortable moments that have the potential to do damage if your words aren’t chosen carefully.You’ll learn graceful ways of pointing out a mistake; asking someone to do something he or she doesn’t want to do; preparing a person for “no”; asking for a big favor; and providing information the recipient doesn’t want to hear.Conversations can only deepen connections when you pull your weight. In How Conversation Works, you’ll learn this involves knowing how to skillfully open and close an exchange, take turns speaking or “negotiate the conversational floor,” and send people subtle signals.Perhaps most important is sharing the burden to make discussions feel more mutual and enjoyable. These lectures arm you with numerous conversation-facilitating devices such as asking your fair share of questions and follow-up questions, which requires active listening; providing informative (but not overly informative!) answers to other people’s questions; introducing new topics for discussion and picking up on the topics of others; and telling good stories and helping good stories along.Talk Your Way to SuccessWhether you want to build rapport with colleagues, promote your accomplishments in an interview, give a winning presentation, ingratiate yourself with your boss, or even create a connection on a first date, knowing what to say and how to say it allows for more productive, smoother interactions. How Conversation Works helps you get ahead by outlining simple techniques for accomplishing all of this and more.Short vignettes featuring professional actors demonstrate what to do—and what not to do—in a variety of everyday scenarios such as striking up a conversation at a party. In video formats, green-screen technology places the professor in a range of environments as she provides concrete advice for taking an uncomfortable conversation in a new direction, making polite requests, mastering the “humble brag,” limiting your “talk time,” and monitoring your use of distracting discourse markers such as “um” and “you know.”In addition to sharing these out-the-door tips and techniques, Professor Curzan dispels common myths about conversation and presents enlightening research on how the conversational styles of men and women share much in common, despite differences in socialization; how you may be perceived for using direct speech or sentence fillers; how language-style matching quickly creates a sense of compatibility; how parents serve as conversational role models; and how e-communication has surprisingly systematic conventions.A Guide for the Real WorldAs a professor of English and linguistics and member of the American Dialect Society, Professor Curzan offers a refreshing yet scholarly take on the subject of conversation. Using a developmental and skills-based approach that gets right to the heart of the matter, her course provides tangible, actionable methods that can be worked into your conversational repertoire immediately. At first, the newfound awareness you’ll acquire from How Conversation Works may cause you to become self-conscious when you speak, but the act of “conversational noticing” will soon become second nature. Before long, you’ll realize you have the tools to make yourself clearly understood, put others at ease, rescue a conversation that’s gone wrong—and keep conversations from going off course in the first place.

    

    His genius as an essayist lies in his unmatched ability to use his knowledge of the world, including popular culture, to illuminate the realm of science.Ever Since Darwin, Stephen Jay Gould's first book, has sold more than a quarter of a million copies.

    For instance, it's not hard to envision a day when websites such as Facebook or Google Maps introduce a feature that allows real-time tracking of anyone you want, based on face-recognition software and ubiquitous live video feeds.Does this scenario sound like an unconstitutional invasion of privacy? These 24 eye-opening lectures immerse you in the Constitution, the courts, and the post-9/11 Internet era that the designers of our legal system could scarcely have imagined. Professor Rosen explains the most pressing legal issues of the modern day and asks how the framers of the U.S. Constitution and the Bill of Rights would have reacted to aspects of the modern life such as full-body scans, cell phone surveillance, and privacy in cloud servers.Called "the nation's most widely read and influential legal commentator" by the Los Angeles Times, Professor Rosen is renowned for his ability to bring legal issues alive - to put real faces and human drama behind the technical issues that cloud many legal discussions. Here he asks how you would decide particular cases about liberty and privacy. You'll come away with a more informed opinion about whether modern life gives even the most innocent among us reason to worry.

    Every night we surrender it gratefully, only to get it back in the morning. We recognize that we have it, but we can never be sure anyone else does. Consciousness, this unique and perplexing mental state, has been the subject of debate for philosophers and scientists for millennia. And while it is widely agreed within contemporary philosophy that consciousness is a problem whose solutions are likely to determine the fate of any number of other problems, there is no settled position on the ultimate nature of consciousness.What is the most promising way to study this subject? What are the implications that arise from the fact that we have consciousness? What are the ethical and moral issues raised by its presence—or its absence? Questions like these are at the heart of Consciousness and Its Implications, 12 thought-provoking lectures delivered by distinguished philosopher and psychologist Daniel N. Robinson. Rather than merely explain away consciousness, or hide behind such convenient slogans as "it's all in your brain," Professor Robinson reviews some of the special problems that philosophers, psychologists, scientists, and doctors face when taking on such a vexing topic.What Is Consciousness? Much of what we do every day is done without our being directly conscious of the steps taken to complete the task: riding a bicycle, taking a walk, humming a tune. But as natural as this state is, it stands as a very serious threat to any number of core convictions and assumptions in both philosophy and science. One of the overarching goals of this intriguing course is to make clear just what about consciousness serves as such a challenge to these convictions and assumptions.But what makes Consciousness and Its Implications so engaging is more than just the nature of the questions it poses and the issues it tackles. It's the way in which Professor Robinson, the consummate teacher and scholar, conveys this goal in four main points, each of which you explore in depth in these lectures.Consciousness seems to require, for its full understanding, a science not yet available. What distinguishes consciousness from all else is its phenomenology—that is, the act of being conscious is different from all other facts of nature. Conscious awareness is a power that, at times, can be so strong as to greatly affect our senses. The powers of consciousness vary over the course of a lifetime; as such, they can become subject to disease and defect.Throughout the course, Professor Robinson brings this riveting topic vividly to life with real-world examples and striking anecdotes. Review the case of Deep Blue, the IBM computer that in 1997 shocked the world by defeating a human, the chess grand master Garry Kasparov. Does Deep Blue's ability to "outsmart" a human being constitute a kind of consciousness? Or is it a reflection of the human minds that created this complex computer? Consider the case of the sleepwalker, who moves around with purpose and mimics behaviors we see in everyday life, but can remember nothing upon awakening. How does this mental state relate to human consciousness? What would be lost if we lived our entire lives as sleepwalkers?Study the case of a comatose patient who lives in an unbroken sleep state but, after a miraculous recovery, recalls having heard doctors speak about her. How do we interpret this patient's ability to perceive the surrounding world while in a coma? Does the patient's experience reflect some in-between mental state we've yet to define? Look at the case of a child with autism who can perform complicated mental tasks but lacks the most basic human attribute: empathy. How does this inability to imagine other minds affect the child's capacity to enjoy the full experience of human consciousness? Using compelling examples such as these, Professor Robinson weaves a riveting tale of the human condition that will change the way you think about your own mind.Professor Robinson also draws on the wisdom of the world's greatest thinkers—from the ancient Greeks to today's top scientists—to shed light on some of the ethical debates involved in any examination of consciousness. These include John Locke, whose famous "Prince and the Cobbler" hypothesis raised questions about the relationship between one's personal identity and one's body; Ludwig Wittgenstein, whose "Beetle in a Box" scenario holds implications for how we define consciousness both inside and outside ourselves; and Aristotle, who led a pointed discussion on the relationship between the physical world and what he referred to as "real being."You also enter the lab and explore the impact of modern physics and medicine on our understanding of the self. Pondering questions ranging from the most fundamental—"Why are we here?"—to contemporary quandaries about artificial intelligence and the medical decision to prolong life, you'll gain new insights into the complexity of how great minds define consciousness.Consciousness and Its Implications is a chance for you to view this deep and profound subject from all angles. A distinguished scholar in philosophy and neuropsychology, Professor Robinson incorporates many disciplines—psychology, physics, philosophy, medicine—to explore these abiding questions. So embark on a challenging and wholly satisfying exploration of this unique, mysterious, and essential mental faculty. The knowledge you'll gain in this course is not only intriguing—it is crucial to understanding the nature of humanity and the social and ethical obligations that define us all.
