Each volume of four 30-minute histories will dig into the petty name-calling and grumbling grudges that led to many of the world’s greatest advancements, all delivered with a cheeky sense of humor.Choose sides: Cope or Marsh, the jerks who discovered so many dinosaurs; Hamilton or Burr, whose rivalry fueled American politics; Queen Elizabeth or Mary Queen of Scots, who fought to rule England; Adidas or Puma, whose rivalry changed the world of sports and fashion.Kidnappings, rock fights, duels, and explosions, Rivals! shows world leaders at their absolute best and their worst, often at the same time.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

    But now, acclaimed linguist Guy Deutscher has dared to reopen the issue. Can culture influence language —and vice versa? Can different languages lead their speakers to different thoughts? Could our experience of the world depend on whether our language has a word for "blue"?Challenging the consensus that the fundaments of language are hard-wired in our genes and thus universal, Deutscher argues that the answer to all these questions is—yes. In thrilling fashion, he takes us from Homer to Darwin, from Yale to the Amazon, from how to name the rainbow to why Russian water —a "she"— becomes a "he" once you dip a tea bag into her, demonstrating that language does in fact reflect culture in ways that are anything but trivial.

    Among those you'll investigate are the accounts of the creation of the world in Hesiod's Theogony and Ovid's Metamorphoses; the gods Zeus, Apollo, Demeter, Persephone, Hermes, Dionysos, and Aphrodite; the Greek heroes, Theseus and Heracles (Hercules in the Roman version); and the most famous of all classical myths, the Trojan War.Professor Vandiver anchors her presentation in some basics. What is a myth? Which societies use myths? What are some of the problems inherent in studying classical mythology? She also discusses the most influential 19th- and 20th-century thinking about myth's nature and function, including the psychological theories of Freud and Jung and the metaphysical approach of Joseph Campbell. You'll also consider the relationship between mythology and culture (such as the implications of the myth of Demeter, Persephone, and Hades for the Greek view of life, death, and marriage), the origins of classical mythology (including the similarities between the Theogony and Mesopotamian creation myths), and the dangers of probing for distant origins (for example, there's little evidence that a prehistoric "mother goddess" lies at the heart of mythology).Taking you from the surprising "truths" about the Minotaur to Ovid's impact on the works of William Shakespeare, these lectures make classical mythology fresh, absorbing, and often surprising.Disclaimer: Please note that this recording may include references to supplemental texts or print references that are not essential to the program and not supplied with your purchase.©2000 The Teaching Company, LLC (P)2000 The Great Courses

    Now - with the technological advances of modern archaeology and a new perspective on world history - we are finally able to piece together their compelling true stories. In Ancient Civilizations of North America, Professor Edwin Barnhart, Director of the Maya Exploration Center, will open your eyes to a fascinating world you never knew existed - even though you've been living right next to it, or even on top of it, for as long as you've been on the continent.The peoples of ancient North America were exceptionally knowledgeable about their environment, but their intellectual and artistic curiosity went much beyond the immediate need for food and safety. Beginning thousands of years ago, and without benefit of written language, native peoples became mathematicians, construction and soil engineers, astronomers, urban planners, and more. They developed thriving cities, extensive trade routes, canals to bring water to the desert, and earthworks we still marvel over today.In 24 exciting lectures, you'll learn about the vibrant cities of Poverty Point, the first city in North America, built about 3,500 years ago, and Cahokia, the largest city of ancient North America. You'll explore the many ways in which the Chacoan environment provided cultural and religious focus for peoples of the southwest. And you'll learn about the Iroquoian source of some of our most basic "American" values.

    It's an occasionally ribald, frequently witty and unerringly erudite guided tour of the secret labyrinth that lurks beneath the English language, taking in monks and monkeys, film buffs and buffaloes, and explaining precisely what the Rolling Stones have to do with gardening.

    Professor Lynne Murphy is on the linguistic front line. In The Prodigal Tongue she explores the fiction and reality of the special relationship between British and American English. By examining the causes and symptoms of American Verbal Inferiority Complex and its flipside, British Verbal Superiority Complex, Murphy unravels the prejudices, stereotypes and insecurities that shape our attitudes to our own language.With great humo(u)r and new insights, Lynne Murphy looks at the social, political and linguistic forces that have driven American and British English in different directions: how Americans got from centre to center, why British accents are growing away from American ones, and what different things we mean when we say estate, frown, or middle class. Is anyone winning this war of the words? Will Yanks and Brits ever really understand each other?

    Acupuncture. Superfoods. Healing magnets. What does the scientific evidence really say about these and other "alternative medicine" treatments for personal wellness?How can we know if a natural remedy is safe and effective? How can people become their own best skeptical consumer of health news in the media? Join neurologist and science educator Dr. Steven Novella for a fascinating exploration of these and other important questions about the truths-and myths-behind alternative medicine.Perhaps the most important skill to have in this brave new world of ever-changing medical news is the ability to evaluate sources and information, and to think critically about how alternative medicine is marketed, regulated, and used. Dr. Novella takes a rigorous, science-based approach in exploring so-called "popular" and "cutting-edge" trends. Armed with this knowledge, listeners will be in a much better position to assess alternative pathways to physical health.Dr. Novella's 10 leading-edge lectures will answer such questions as: Do magnetic fields really have useful biological properties? Why is chiropractic treatment no more effective for pain management than simple physical therapy? Can brain games truly make one smarter or help in staving off dementia? Can homeopathic remedies, such as those derived from plants and minerals, really cure ailments? Does cupping therapy really help to reduce pain and inflammation, while increasing blood flow?Dr. Novella provides insights on the ever-widening gap between alternative medicine and

    But the Black Death was arguably the most significant event in Western history, profoundly affecting every aspect of human life, from the economic and social to the political, religious, and cultural. In its wake the plague left a world that was utterly changed, forever altering the traditional structure of European societies and forcing a rethinking of every single system of Western civilization: food production and trade, the church, political institutions, law, art, and more. In large measure, by the profundity of the changes it brought, the Black Death produced the modern world we live in today.While the story of the Black Death is one of destruction and loss, its breathtaking scope and effects make it one of the most compelling and deeply intriguing episodes in human history. Understanding the remarkable unfolding of the plague and its aftermath provides a highly revealing window not only on the medieval world but also on the forces that brought about the Renaissance, the Protestant Reformation, and modernity itself.Speaking to the full magnitude of this world-changing historical moment, The Black Death: The World's Most Devastating Plague, taught by celebrated medievalist Dorsey Armstrong of Purdue University, takes you on an unforgettable excursion into the time period of the plague, its full human repercussions, and its transformative effects on European civilization. In 24 richly absorbing lectures, you'll follow the path of the epidemic in its complete trajectory across medieval Europe. Majestic in scope and remarkable in detail, this course goes to the heart of one of Western history's most catalytic and galvanizing moments, the effects of which gave us the modern world.

    Language is humanity's most spectacular open-source project, and the internet is making our language change faster and in more interesting ways than ever before. Internet conversations are structured by the shape of our apps and platforms, from the grammar of status updates to the protocols of comments and @replies. Linguistically inventive online communities spread new slang and jargon with dizzying speed. What's more, social media is a vast laboratory of unedited, unfiltered words where we can watch language evolve in real time.Even the most absurd-looking slang has genuine patterns behind it. Internet linguist Gretchen McCulloch explores the deep forces that shape human language and influence the way we communicate with one another. She explains how your first social internet experience influences whether you prefer "LOL" or "lol," why ~sparkly tildes~ succeeded where centuries of proposals for irony punctuation had failed, what emoji have in common with physical gestures, and how the artfully disarrayed language of animal memes like lolcats and doggo made them more likely to spread.Because Internet is essential reading for anyone who's ever puzzled over how to punctuate a text message or wondered where memes come from. It's the perfect book for understanding how the internet is changing the English language, why that's a good thing, and what our online interactions reveal about who we are.
