    A series of 24 lectures comprising a course on comparative religion presented by Charles Kimball, director of the Religious Studies Program at the University of Oklahoma.

    By studying the physical astronomy of all the planets in the Solar System, we can attempt to understand their true nature. Ultimately, these lectures will bring us to a greater understanding of the Solar System's creation, which brings us again back to the beginning and what it means to us as we look outward from our rotating Earth.

    Disease. Starvation. Cannibals. From the ancient wayfarers to modern astronauts, world explorers have blazed trails fraught with danger. Yet, as History's Greatest Voyages of Exploration vividly demonstrates, exploration continues to be one of humanity's deepest impulses.Across 24 lectures that unveil the process by which we came to know the far reaches of our planet, you'll witness the awe-inspiring and surprisingly interconnected tale of global exploration. An award-winning history professor from the University of Tennessee, Knoxville, revolutionizes how you view the world as he introduces you to some of the greatest and most influential explorers ever known-successful as well as unsuccessful, admirable as well as flawed. You'll be spellbound as you learn of the treacherous, at times fatal, expeditions into the unknown these adventurers embarked upon, whether to the frozen Poles, Asia, Europe, the Americas, Africa, the ocean's depths, or the final frontier of space.Through it all, you consider what drove these intrepid individuals, from proselytizing and pilgrimage to the lure of wealth, conquest, fame, and new lands, as evidenced by the Vikings' arrival in North America; Marco Polo's journey along the Silk Road to China; Christopher Columbus' "Enterprise of the Indies"; the conquistadors' ravages in Latin America; and the tiny kingdom of Portugal's triumphant circumnavigation of Africa to seize control of trade in the Indian Ocean.In every lesson, you'll follow these fascinating figures - including several remarkable women - as they venture into uncharted territory and put themselves, and often their crews, in dire peril. With Professor Liulevicius' uniquely global approach, you also get a meaningful portrait of the travels of non-Westerners, as well as the perspectives of discovered people.

    There are good reasons that language fascinates us so. It not only defines humans as a species, placing us head and shoulders above even the most proficient animal communicators, but it also beguiles us with its endless mysteries. For example: * How did different languages come to be? * Why isn’t there just a single language? * How does a language change, and when it does, is that change indicative of decay or growth? * How does a language become extinct? Dr. John McWhorter, one of America’s leading linguists and a frequent commentator on network television and National Public Radio, addresses these and other questions as he takes you on an in-depth, 36-lecture tour of the development of human language, showing how a single tongue spoken 150,000 years ago has evolved into the estimated 6,000 languages used around the world today.An accomplished scholar, Professor McWhorter is also a skilled popularizer, whose book The Power of Babel was called "startling, provocative, and remarkably entertaining," by the San Diego Union-Tribune.The London Times called him "a born teacher." And Steven Pinker, best known as the author of The Language Instinct, offered this praise for the book: "McWhorter’s arguments are sharply reasoned, refreshingly honest, and thoroughly original."Course Lecture Titles1.

    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

    More than 2,500 years later, the issues they pondered continue to challenge, fascinate, and instruct us. Is reality stable and permanent or is it always changing? Are ethical values like justice and courage relative? Or are values "absolute"—simply and forever right and true? What is justice? What is happiness? How shall we best live our lives?An Introduction to Greek Philosophy beckons you to join this eternal discussion. For that is what this subject truly is: a conversation among thinkers that has continued through the centuries and remains accessible to us today. You find it constantly stimulating, sometimes controversial, and nearly always remarkably relevant.A Hunger for Reasons, not Myths or BeliefsProfessor David Roochnik has organized this series of 24 lectures as a "dialectical" approach (the word comes from the Greek dialegesthai: to converse). The philosophers are presented as if they were participating in a conversation. In this way, the course unfolds in a manner similar to the actual development of Greek philosophy.In this course, you study the development of Greek philosophy, meet its major thinkers, and explore the issues and ideas that concerned them. For example the first real philosophers were the Presocratics—literally, the philosophers who lived before Socrates. They included Thales of Miletus (585 B.C.E.–?), Anaximander (610–546), Anaximenes (approx. 550), Xenophanes (approx. 570) and Pythagoras (approx. 570–500).The Presocratics rejected myth and divine inspiration—such as had been embodied in the works of Homer and in Hesiod's creation story, the Theogony—as valid explanations of reality. Instead, they insisted that true understanding always requires a logos, a rational explanation (hence such English words as "psychology" and "biology").The Presocratics were concerned with issues such as identifying the arche or "Being": the thing that is the origin of all other things. They also introduced sophistic relativism, the notion that truth, goodness, and all other values were relative, depending entirely on the person or group that held them. This concept would become a major point of debate for the Greeks and for the ages.Are We Footnotes to Plato?The heroes of this course, and certainly of Greek philosophy, are Plato (429–347 B.C.E.) and his student, Aristotle (384–322 B.C.E.). Unlike the Presocratics, who wrote too little, Plato and Aristotle were prolific authors. Both argued against relativism and instead were staunch objectivists who believed that certain important values were absolutely and universally true. And both left a staggering mark on history.Alfred North Whitehead, the great 20th-century British philosopher, said, "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." In the Middle Ages, Aristotle was held in such high esteem that he was simply known as "the philosopher."Among Plato's many contributions to philosophy is his ingenious device for the examination of ideas: his written dialogues. In them, Plato never uses his own voice. Instead, the dialogues take place among a changing cast of characters, and Socrates is the most notable among them. The effect is to invite us to take part in the conversation and, ultimately, to become philosophers.You study Plato's dialogues as well as his notion of the Forms. This was his response to relativism and proposed that every virtue and value has an absolute and perfect Form, which humans understand even before birth.Greek philosophy can be said to culminate with Aristotle, who wrote treatises on a breathtaking range of subjects. He is said to be the first to view knowledge as being divided into specific disciplines such as biology or astronomy. The university was later modeled on this approach. More than any other philosopher, Aristotle synthesized the views that preceded him.For Aristotle, one value was foremost and was contained in everything, from the tiniest organisms to the phenomena of fire to human beings: purpose. Everything has a purpose that can be recognized and objectively defined, and that gives meaning to life. You explore the details and rationale of Aristotle's teleological—or purposive—world-view, one of the most significant in history.An Invitation to ThinkIn this course, you not only learn about Greek philosophy but, to some extent, how to do it. Professor Roochnik emphasizes that Greek philosophy is ultimately not about facts or answers but about the give-and-take of ideas.By the end of these lectures, you will understand how Greek philosophy still heavily influences our view of life. We live today, Professor Roochnik maintains, at a time that is shaped by Presocratic, relativistic philosophy. Contemporary thinkers, and often the average person, have great difficulty finding objective truth or meaning in life.What have we lost in turning away from the world of Plato and Aristotle—a world where everything has a place and a purpose and life is saturated with value and meaning?On the other hand, what would we lose if we returned to that world?These are a few of the many questions that will give you ample food for thought. For the Greeks, that was the greatest feast of all.

    It examines the canonical Gospels of Mark, Matthew, Luke, and John familiar to us from the New Testament, as well as the many other, apocryphal narratives and literary works that have contributed to our perceptions of Jesus, Mary, and Christianity. All of these works are encompassed by the word "Gospel."

    These icons of science fiction are now in our daily news. Science fiction, once maligned as mere pulp, has motivated cutting-edge scientific research, inspired new technologies, and changed how we view everyday life - and its themes and questions permeate popular culture. Take an unparalleled look at the influence, history, and greatest works of science fiction with illuminating insights and fascinating facts about this wide-ranging genre. If you think science fiction doesn't have anything to do with you, this course deserves your attention. And if you love science fiction, you can't miss this opportunity to trace the arc of science fiction's evolution, understand the hallmarks of great science fiction, and delve deeply into classics while finding some new favorites.These 24 captivating lectures reveal the qualities that make science fiction an enduring phenomenon that has been steadily gaining popularity. You'll grasp the context and achievements of authors like Arthur C. Clarke, H.G. Wells, Isaac Asimov, Ursula K. LeGuin, and many more. You'll experience the wonder, horror, and incredible imagination of works like Frankenstein, the Foundation series, Stranger in a Strange Land, and dozens of more recent stories as well. You'll also see this genre's influence in movies like Star Wars and TV shows like The Twilight Zone.Science fiction can take us places in time and space where no other form of fiction can - outer space, the far future, alternate universes, unfathomable civilizations. The best science fiction expands our imaginations and makes its mark on our reality. And while few writers would ever claim to predict the future, sometimes authors get it almost eerily right: Gernsback describing radar in 1911, Bradbury describing giant flatscreen TVs in 1951, Gibson inventing "cyberspace" in 1984, and so on.

    And while many of us look to make sense of Russia through its political history, in many ways a real grasp of this awe-inspiring country comes from looking closely at its cultural achievements. The 24 lectures of Understanding Russia: A Cultural History survey hundreds of years of Russian culture, from the world of Ivan the Terrible to the dawn of the Soviet Union to the post-war tensions of Putin's Russia. Blending history with cultural studies, they are designed to bring you closer than ever before to the Russian people - not just the authoritarian rulers like Peter the Great, the Romanovs, and Stalin but the everyday men and women who sought their own meaning in the poetry of Pushkin, the comfort of early folk tales, the faith of medieval iconography, the avant-garde films of Eisenstein, and more. You'll discover surprising insights into centuries of cultural history, including peasant superstitions, such as avoiding whistling indoors, and the culture of queuing for goods and services that defined everyday life for ordinary Soviets. You'll also spend time in the company of novelists, painters, poets, filmmakers, impresarios, composers, revolutionaries, and intellectuals who shaped Russia in myriad ways, including The Five, a group of composers who created a distinctly national sound based in part on Russian folk music; and Sergei Eisenstein, the filmmaker whose Battleship Potemkin revolutionized the language of cinema. In a time when the eyes of the Western world are constantly drawn to Russia, it's amazing how little we really know about its culture. These lectures will help you finally understand that complex, thrilling, and undeniably fascinating spirit.
