Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves. By some estimates, roughly one in four Americans might be considered addicts. On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction. So what is the difference between drug use, abuse, and clinical addiction? What causes addictions? What happens when your brain is on drugs, and why do addicts behave the way they do?12 Lectures 1.

    And it has an undeniable power to move us in ways that enrich our lives - provided it is understood.If you have ever longed to appreciate great concert music, to learn its glorious language and share in its sublime pleasures, the way is now open to you, through this series of 48 wonderful lectures designed to make music accessible to everyone who yearns to know it, regardless of prior training or knowledge. It's a lecture series that will enable you to first grasp music's forms, techniques, and terms - the grammatical elements that make you fluent in its language - and then use that newfound fluency to finally hear and understand what the greatest composers in history are actually saying to us.And as you learn the gifts given us by nearly every major composer, you'll come to know there is one we share with each of them - a common humanity that lets us finally understand that these were simply people speaking to us, sharing their passion and wanting desperately to be heard. Using digitally recorded musical passages to illustrate his points, Professor Greenberg will take you inside magnificent compositions by Bach, Handel, Haydn, Mozart, Beethoven, Chopin, Verdi, Wagner, Brahms, Tchaikovsky, Stravinsky, and more. Even if you have listened to many of these illustrative pieces throughout your life - as so many of us have - you will never hear them the same way again after experiencing these lectures.

    David Christian, professor of history at San Diego State University, surveys the past at all possible scales, from conventional history, to the much larger scales of biology and geology, to the universal scales of cosmology.

    As traders and raiders, explorers and colonists, they reshaped the world between eastern North America and the Asian steppe. For a millennium, though, their history has largely been filtered through the writings of their victims. Based on the latest archaeological and textual evidence, Children of Ash and Elm tells the story of the Vikings on their own terms: their politics, their cosmology, their art and culture. From Björn Ironside, who led an expedition to sack Rome, to Gudrid Thorbjarnardóttir, the most travelled woman in the world, Price shows us the real Vikings, not the caricatures they have become in popular culture and history.

    But who were the early speakers of this ancient mother tongue, and how did they manage to spread it around the globe? Until now their identity has remained a tantalizing mystery to linguists, archaeologists, and even Nazis seeking the roots of the Aryan race. The Horse, the Wheel, and Language lifts the veil that has long shrouded these original Indo-European speakers, and reveals how their domestication of horses and use of the wheel spread language and transformed civilization.Linking prehistoric archaeological remains with the development of language, David Anthony identifies the prehistoric peoples of central Eurasia's steppe grasslands as the original speakers of Proto-Indo-European, and shows how their innovative use of the ox wagon, horseback riding, and the warrior's chariot turned the Eurasian steppes into a thriving transcontinental corridor of communication, commerce, and cultural exchange. He explains how they spread their traditions and gave rise to important advances in copper mining, warfare, and patron-client political institutions, thereby ushering in an era of vibrant social change. Anthony also describes his fascinating discovery of how the wear from bits on ancient horse teeth reveals the origins of horseback riding.The Horse, the Wheel, and Language solves a puzzle that has vexed scholars for two centuries--the source of the Indo-European languages and English--and recovers a magnificent and influential civilization from the past.

    As much as we'd like to cultivate these same skills, the truth is that you cannot know how a lawyer thinks and works without studying the law itself.Now there's an easier way to get the same foundational knowledge as lawyers - without the enormous time and financial commitment. Over the span of 48 lectures, four experienced lawyers and teachers recreate key parts of the first-year law student experience, introducing you to main areas of law most every beginning student studies.You'll start with 12 lectures on litigation and legal practice that offer eye-opening answers to many questions about the art and craft of legislation. In the second 12 lectures, you'll learn how criminal law and procedure - an area of law dramatized by countless TV shows - really works. Additional lectures investigate the civic procedures courts follow to resolve disputes about substantive rights and examine broader questions any system of litigation must address. And 12 lectures are devoted entirely to the stranger-than-fiction topic of tort law.Enriched with famous cases from the annals of American law and powerful arguments by some of history's most successful lawyers, these lectures offer access to an often intimidating, surprisingly accessible, and civically important field.

    Offering multilevel insight into one of the most astounding real-life dramas of modern history, The Fall and Rise of China weaves together the richly diverse developments and sociopolitical currents that created the China we now see in the headlines.As we enter what some are already calling the "Chinese century," the role of China is deeply fundamental to our reading of the direction of world civilization and history. In 48 penetrating lectures, The Fall and Rise of China takes you to the heart of the events behind China's new global presence, leaving you with a clear view of both the story itself and its critical implications for our world.Course Lecture Titles48 Lectures, 30 minutes per lecture 1.

    Central to many spiritual and philosophical traditions and known in English as "meditation," these practices are considered a major means for enhanced awareness and self-mastery. In recent decades, modern science has dramatically confirmed what advanced meditators have long claimed—that meditation, correctly practiced, offers deep and lasting benefits for mental functioning and emotional health, as well as for physical health and well-being.

    But there is a method for avoiding such pitfalls of human nature, and it's called skepticism. By using rational inquiry and seeing subjects from a scientific perspective, we can approach even the most sensitive claims with clear eyes to ultimately arrive at the truth. During 18 lectures that will surprise, challenge, and entertain you, you will learn how to think, not just what to think-and you'll come to understand why extraordinary claims require extraordinary evidence.You'll discover how skepticism can help differentiate between real science and pseudoscience, as well as between "scientific" history and pseudohistory-distinctions that have serious educational and political implications.Fascinating case studies illustrate how you can apply the methods of skepticism to detect specious claims and faulty logic in any scenario you encounter such as:•The methodology employed by Holocaust deniers•Arguments made by proponents of creationism•The biology of near-death experiences and the sensed-presence effect•Psychic abilities and other "paranormal" phenomena.As you learn how our brains work to form beliefs, you'll examine the classic fallacies of thought that lead us to experience mistakes in thinking and to form bad arguments in favor of our beliefs.Is there a God? Is there life after death? Is there a basis for morality without God? Skepticism 101 doesn't shy away from controversial questions, nor does it give final answers. What it offers are methods and hard evidence for rationally evaluating various claims and positions, and an opportunity to understand why you believe what you believe.Listening Length: 9 hours and 10 minutes

    Caffeine, it turns out, has changed the course of human history - won and lost wars, changed politics, dominated economies. What's more, the author shows that the Industrial Revolution would have been impossible without it. The science of how the drug has evolved to addict us is no less fascinating.

    Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."
