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.

    In their new book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about the mysteries of the universe, in nontechnical language marked by both brilliance and simplicity. In The Grand Design they explain that according to quantum theory, the cosmos does not have just a single existence or history, but rather that every possible history of the universe exists simultaneously. When applied to the universe as a whole, this idea calls into question the very notion of cause and effect. But the “top-down” approach to cosmology that Hawking and Mlodinow describe would say that the fact that the past takes no definite form means that we create history by observing it, rather than that history creates us. The authors further explain that we ourselves are the product of quantum fluctuations in the very early universe, and show how quantum theory predicts the “multiverse”—the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature.Along the way Hawking and Mlodinow question the conventional concept of reality, posing a “model-dependent” theory of reality as the best we can hope to find. And they conclude with a riveting assessment of M-theory, an explanation of the laws governing us and our universe that is currently the only viable candidate for a complete “theory of everything.” If confirmed, they write, it will be the unified theory that Einstein was looking for, and the ultimate triumph of human reason.A succinct, startling, and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform—and provoke—like no other.'

    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

    How do different food groups affect our bodies depending on the activity—from biking and running to hiking and basketball?

Each lecture addresses some of the myths and realities concerning the relationship between nutrition and fitness.

    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.

    For example, the matter that comprises all stars, planets, and living things turns out to be just a fraction of what actually exists. Moreover, we think that we control our actions, but data analytics can predict, with astonishing accuracy, when we will wake up, what we will buy, and even whom we will marry.The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality. And we have developed the power to alter our own reality in major ways - to defeat diseases, compensate for disabilities, and augment our intellect with computers. Where is that trend going?Experience the thrill of this exciting quest in 36 wide-ranging lectures that touch on many aspects of the ceaseless search for reality. From the birth of the universe to brain science, discover that separating the real from the illusory is an exhilarating intellectual adventure.Scientists and philosophers are not alone in grappling, at an intellectual level, with reality. Some of the most accessible interpretations are by painters, novelists, filmmakers, and other artists whose works not only draw on the latest discoveries but also sometimes inspire them. Explore examples such as Alice in Wonderland, pointillism, cubism, surrealism, and reality TV.And since dealing with reality is an experience we all share, this course is designed for people of all backgrounds.
