Fewer records were kept, leaving an often-empty legacy to historians attempting to understand the age.But modern archaeology has begun to unearth an increasing number of clues to this once-lost era. And as historians have joined them to sift through those clues—including evidence of a vast arc of Viking trade reaching from Scandinavia to Asia—new light has begun to fall across those once "dark" ages and their fascinating personalities and events.

    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

    But this attitude is a relatively recent development in the sweep of history. In The Pun Also Rises, John Pollack — a former Presidential Speechwriter for Bill Clinton, and winner of the world pun championship — explains how punning revolutionized language and made possible the rise of modern civilization. Integrating evidence from history, pop culture, literature, comedy, science, business and everyday life, this book will make readers reconsider everything they think they know about puns.

    But is old age all doom and gloom?Not at all! While it's true that some functions in the aging brain decline, neuroscientists have discovered that many other brain functions remain stable - or even improve - as we age. Furthermore, nurture plays as significant a role as nature, and there are a number of strategies you can implement to stave off declining brain function, including:Incorporating physical activity into your routineEating a healthy dietMaintaining a vibrant social lifeReducing your stressThe science behind the aging brain tells a fascinating - and often counterintuitive - story. Is "aging" a disease or merely a natural occurrence that produces disease-like symptoms? If humans are biologically programmed to survive and thrive, why do we age at all? Is it possible (or even desirable) to "cure" aging altogether?Delve into these questions and more in The Aging Brain. Taught by a neuroscientist and award-winning professor at the University of Michigan, these 12 eye-opening lectures will give you a wealth of new insights into what happens to the brain over time - as well as strategies to mitigate the effects of aging and enhance your quality of life into old age.With a mix of scientific research and practical applications, Professor Polk brings cutting-edge science to life. He takes you down to the cellular and even molecular levels of the brain to show you why certain functions decline, how some aspects of brain aging are under genetic control, and what you can do to prolong your health and keep your mind sharp. Aging affects us all, but you have some control over how it affects you.

    to A.D. 1600. The lectures begin by asking just what "Western civilization" actually is, or what it has been thought to be. Throughout the lectures, there are reflections on where Western civilization finds its primary locus at any given moment - beginning in the ancient Near East and moving to Greece, then to Rome; exploring the shape and impact of large ancient empires, including the Persian, Alexander the Great's, and Rome's; then moving on to Western Europe, and witnessing Europe's gradual physical and cultural expansion, into finally the globalization of Western civilization with the Portuguese and Spanish voyages of exploration and discovery.

    It is democratic, everchanging and ingenious in its assimilation of other cultures. English runs through the heart of the world of finance, medicine and the Internet, and it is understood by around two thousand million people across the world. It seems set to go on. Yet it was nearly wiped out in its early years.Embracing elements of Latin, French, Spanish, Italian, Portuguese, Arabic, Hindi and Gullah, this 1500-year story covers a huge range of countries and people. The Adventure of English is not only an enthralling story of power, religion and trade, but also the story of people, and how their day-to-day lives shaped and continue to change the extraordinary language that is English.

    (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world. Welcome to the science wars—a long-running battle over the status of scientific knowledge that began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has re-emerged in today's conflict between science and religion over issues such as evolution.Professor Steven L. Goldman, whose Teaching Company course on Science in the 20th Century was praised by customers as "a scholarly achievement of the highest order" and "excellent in every way," leads you on a quest for the nature of scientific reasoning in this intellectually pathbreaking lecture series, Science Wars: What Scientists Know and How They Know It.Those who have taken Professor Goldman's previous course, which is an intensive survey of the revolution in scientific knowledge from 1900 to 2000, may have wondered: if what counts as scientific knowledge can transform so dramatically within only 100 years, what exactly is scientific knowledge? Science Wars addresses this surprisingly difficult question.Five Centuries of the Science WarsIn 24 half-hour lectures, Science Wars explores the history of competing conceptions of scientific knowledge and their implications for science and society from the onset of the Scientific Revolution in the 1600s to the present. It may seem that the accelerating pace of discoveries, inventions, and unexpected insights into nature during this period guarantees the secure foundations of scientific inquiry, but that is far from true. Consider these cases:The scientific method: In the 1600s the English philosopher Francis Bacon defined the scientific method in its classic form: the use of inductive reasoning to draw conclusions from an exhaustive body of facts. But "no scientist has ever been a strict Baconian," says Professor Goldman. "If you followed that, you would get nowhere."A "heated" debate: Around 1800 the dispute over the nature of heat was resolved in favor of the theory that heat is motion and not a substance given off during burning. But then the French mathematical physicist Joseph Fourier wrote a set of equations that accurately described how heat behaves regardless of what it "really" is, which, Fourier contended, was not a scientific question at all.Paradigm shifts: The publication in 1962 of Thomas Kuhn's The Structure of Scientific Revolutions precipitated a radical change in attitudes toward scientific knowledge, prompted by Kuhn's insight that science is not an entirely rational enterprise, and that its well-established theories (or paradigms) are overturned in a revolutionary, nonlogical process.Postmodern putdown: The postmodern attack on science as a privileged mode of inquiry made some headway in the late 20th century. But the credibility of the movement wilted in 1996, when a postmodern journal unwittingly published a spoof by physicist Alan Sokal, purporting to prove that physical theory was socially constructed. Sokal then exposed his piece as a parody.In the penultimate lecture of the course, Professor Goldman considers intelligent design—the argument that evolution can't account for the immense complexity of life and that a master designer must be at work. He approaches this topical debate by asking: What are the minimum criteria that define a hypothesis as scientific, and does intelligent design qualify? Having already covered five centuries of the science wars in the previous lectures, you will analyze this controversy with a set of tools that allows you to see the issues in a sharp, new light.What Is Reality?"Fasten your seatbelts," says Professor Goldman at the outset of Lecture 21—an advisory that applies equally to the whole course, which covers an astonishing array of ideas and thinkers. Throughout, Professor Goldman never loses his narrative thread, which begins 2,400 years ago with Plato's allegorical battle between "the gods" and "the earth giants"—between those for whom knowledge is universal, necessary, and certain; and those for whom it cannot be so and is based wholly on experience.The problem of what constitutes scientific knowledge can be illustrated with one of the most famous and widely accepted scientific theories of all time, Nicolaus Copernicus's heliostatic (stationary sun) theory of the solar system, which has undergone continual change since it was first proposed in 1543: Copernicus called for the planets to move in uniform circular motion around the sun, slightly displaced from the center. Using observations by Tycho Brahe, Johannes Kepler revised the Copernican model, discarding the ancient dogma of circular motion, which did not fit the data. Instead, he guessed that the planets in fact move in elliptical orbits. In his influential work endorsing the Copernican theory, Galileo ignored Kepler's corrections and opted for circular motion. Notoriously, the Catholic Church condemned Galileo for heresy. But the church was actually correct that he had no basis for claiming the heliocentric theory was true, rather than simply an interpretation of experience. Galileo's picture of space was superseded by Newton's and later by Einstein's, which also will doubtless be revised. Even something as basic as the elliptical motion of the planets is a vast oversimplification. There are no closed curves in space, since the solar system is moving around the center of the galaxy; the galaxy is moving within the local cluster; and the local cluster is also moving. Although we still call the conventional picture of the solar system Copernican astronomy, there is effectively no resemblance between astronomy today and Copernicus's 1543 theory of the heavens. The same is also true of other theories, such as the atomic theory of matter. All scientific theories are in a state of ceaseless revision, which raises the question of what reality "really" is. As the contemporary philosopher of science Mary Hesse has pointed out, the lesson of the history of science seems to be that the theories we currently hold to be true are as likely to be overturned as the theories they replaced!Sharpen Your Understanding of What Science IsThe uncertainty about the status of scientific knowledge and about the objectivity of the scientific enterprise led to a broad assault on science in the late 20th century by sociologists, philosophers, and historians, many connected with the postmodern movement. The lectures covering this attack and the ensuing counterattack by scientists are some of the most thrilling in the course and involve a number of figures whom Professor Goldman knows personally.Of one of the firebrands in this conflict, the late Viennese philosopher of science Paul Feyerabend, Professor Goldman says, "I myself took a seminar with Feyerabend when he was teaching at Berkeley in the early 1960s. … Feyerabend was not really off the wall, although he was often depicted that way. … He too recognized, as everyone must, that after all, science does work and science is knowledge of a sort. It's just not the absolute knowledge that scientists and philosophers have historically claimed that it is."By the time you reach the end of this course, you will understand exactly what science is, and you will be enlightened about a fascinating problem that perhaps you didn't even know existed. "There have been a raft of popular books about what scientists know," says Professor Goldman, "but to the best of my knowledge, there is not a single one of these popular books that focuses centrally on the question of how scientists know what they know."This course serves as that book.Course Lecture Titles1.

    With humor and insight, Melissa Mohr takes readers on a journey to discover how "swearing" has come to include both testifying with your hand on the Bible and calling someone a *#$&!* when they cut you off on the highway. She explores obscenities in ancient Rome and unearths the history of religious oaths in the Middle Ages, when swearing (or not swearing) an oath was often a matter of life and death. Holy Sh*t also explains the advancement of civility and corresponding censorship of language in the 18th century, considers the rise of racial slurs after World War II, examines the physiological effects of swearing and answers a question that preoccupies the FCC, the US Senate, and anyone who has recently overheard little kids at a playground: are we swearing more now than people did in the past?A gem of lexicography and cultural history, Holy Sh*t is a serious exploration of obscenity.
