    This makes economic history - the study of how civilizations structured their environments to provide food, shelter, and material goods - a vital lens through which to think about how we arrived at our present, globalized moment.Designed to fill a long-empty gap in how we think about modern history, these 48 lectures are a comprehensive journey through more than 600 years of economic history, from the medieval world to the 21st century. Aimed at the layperson with only a cursory understanding of the field, An Economic History of the World since 1400 reveals how economics has influenced (and been influenced by) historical events and trends, including the Black Death, the Age of Exploration, the Industrial Revolution, the European colonization of Africa, the collapse of the Soviet Union, and the birth of personal computing. Professor Harreld has crafted a riveting, centuries-long story of power, glory, and ideology that reveals how, in step with history, economic ideas emerged, evolved, and thrived or died.Along the way, you'll strengthen your understanding of a range of economic concepts, philosophies, trends, treaties, and organizations, including the mercantile system, Adam Smith's The Wealth of Nations, Marxist economics, African independence movements, and the formation of economic organizations including the European Union. You'll also consider provocative questions about the intersection of history and economics. What did the economies of Roosevelt's America and Hitler's Germany have in common? What does history tell us about how nations should dictate economic policy? Can we say that free trade is truly free?Marvel at just how much we still have to learn about the economic forces that have dictated our past - and that will dictate our future.Listening Length: 24 hours and 29 minutes

    It starts in your mother's womb, accelerates to high speed in infancy and childhood, and continues through every age, whether you're actively engaged in mastering a new skill, intuitively discovering an unfamiliar place, or just sleeping, which is fundamental to helping you consolidate and hold on to what you've learned. You are truly born to learn around the clock.But few of us know how we learn, which is the key to learning and studying more effectively. For example, you may be surprised by the following:People tend to misjudge what they have learned well, what they don't yet know, and what they do and do not need to practice.Moments of confusion, frustration, uncertainty, and lack of confidence are part of the process of acquiring new skills and new knowledge.Humans and animals explore their worlds for the sake of learning, regardless of rewards and punishment connected with success.You can teach an old dog new tricks. In fact, older learners have the benefit of prior knowledge and critical skills—two advantages in learning.Shedding light on what's going on when we learn and dispelling common myths about the subject, How We Learn introduces you to this practical and accessible science in 24 half-hour lectures presented by Professor Monisha Pasupathi of the University of Utah, an award-winning psychology teacher and expert on how people of all ages learn.

    These unabridged essays by Carl Sagan were originally published in either popular science magazines or academic journals. This is the first time his essays have become available on audio.

    Thought to be buried somewhere within the Mato Grosso region of the Amazon rainforest, the lure of the vanished riches has long proven deadly to treasure-seekers who brave the forbidding wilderness and mysterious creatures in search of it. Disgraced historian Dr. Hunter Winslow, fired from a lucrative professorship for stealing rare documents in order to gain a competitive edge over his colleagues, thinks the key to Manuscript 512 lies not in its words, but in its paper itself. The only problem is that to confirm his hypothesis means to destroy the document, something the Brazil National Library in Rio de Janeiro will never allow. But old habits die hard, and Hunter knows his way around a Special Collections room. After a brazen theft that triggers an international manhunt, the rogue historian is able to reveal the document’s secrets in a way no one else can, or ever will be able to again—by using its physical properties to reveal missing sections that had supposedly been irreversibly damaged. Armed with this new information, Hunter embarks on an expedition to the deepest Amazon to put to rest the mystery of the lost city once and for all. But while Hunter is looking for the fabled treasure, the long arm of the law is looking for him. Will they catch up to him before he can locate the treasure of a thousand lifetimes, or will he become as lost as the city he seeks?

    With clear explanations of some of the most complex scientific endeavors in history, Mahaffey's new book looks back at the atom's wild, secretive past and then toward its potentially bright future.Mahaffey unearths lost reactors on far flung Pacific islands and trees that were exposed to active fission that changed gender or bloomed in the dead of winter. He explains why we have nuclear submarines but not nuclear aircraft and why cold fusion doesn't exist. And who knew that radiation counting was once a fashionable trend? Though parts of the nuclear history might seem like a fiction mash-up, where cowboys somehow got a hold of a reactor, Mahaffey's vivid prose holds the reader in thrall of the infectious energy of scientific curiosity and ingenuity that may one day hold the key to solving our energy crisis or sending us to Mars.

    A starry night is one of nature's most magical wonders, yet in our artificially lit world, three-quarters of Americans' eyes never switch to night vision, and most no longer experience true darkness. In The End of Night, Paul Bogard restores awareness of the spectacularly primal, wildly dark night sky and how it has influenced the human experience across everything from science to art.From Las Vegas's Luxor Beam (the brightest single spot on this planet) to nights so starlit the sky looks like snow, Bogard blends personal narrative, natural history, science, and history to shed light on the importance of darkness--what we've lost, what we still have, and what we might regain--and the simple ways we can reduce the brightness of our nights tonight.

    What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? The Theory of Evolution: A History of Controversy is an examination of the varied elements that so often make this science the object of strong sentiments and heated debate. Professor Edward J. Larson leads you through the "evolution" of evolution, with an eye toward enhancing your understanding of the development of the theory itself and the roots of the controversies that surround it. In these lectures you will: Explore pre-Darwinian theories of the origins of life, from Genesis and the ancient Greeks to such 18th- and 19th-century scientists as Georges Cuvier and Chevalier de Lamarck Follow the life and work of Charles Darwin, and the impact of his 1859 masterpiece, On the Origin of Species. Darwin's theory of evolution by natural selection was immediately recognized as a threat to traditional religion, but was quickly accepted (the first printing of Origin of Species sold out on the first day) Examine the history of evolutionary science after Darwin-a fascinating story that includes the "rediscovery," after 35 years, of Gregor Mendel's work on genetic variation; the unearthing of prehominid, or early human, fossils by Raymond Dart in 1925 and the Leakey family in the 1950s; and the confusion created by the sensational, but later discredited, discovery of Piltdown Man-a fake evolutionary "missing link"-in 1912 Trace the history of religious objections to evolution, from those of Darwin's own time to contemporary efforts to teach creation science in American schools. This includes a detailed discussion of the famous Scopes "monkey trial," which in fact was a staged media event, designed to create publicity for the town of Dayton, Tennessee. Are Our Genes more Important than We Are? This course makes it clear that the history of controversy surrounding evolution is not limited to a dispute between science and religion. Even within the scientific community, the fine details of the theory of evolution have long been a matter of passionate dispute. In fact, in the last third of the 19th century, the principal objections were scientific, not religious. Although the fossil record was a key piece of evidence for evolution, it had gaps that could be used to argue against the theory. And both proponents and critics wondered how altruistic human qualities such as love and generosity could possibly have evolved through the competitive, often harsh, processes that Darwin described. From Professor Larson's presentation, you will learn that new ideas in evolution science have often created new controversies. For example, is it truly possible, as some scientists now maintain, that humans exist merely to ensure the survival of their genes? Such research has created disagreement among scientists about the degree to which evolution drives human behavior, and has further alienated many segments of the public. Evolution's "Dark Side": Social Darwinism In these lectures, you will review perhaps the most sinister controversy associated with the theory of evolution: social Darwinism. From the beginning, the Darwinian theory of evolution has been linked to economic and political views. Thomas Malthus's theories of population growth and competition for limited resources even inspired Darwin's thinking on natural selection. Unfortunately, later supporters of evolution carried this line of thinking too far. Beginning with Herbert Spencer, who coined the term "survival of the fittest," Darwin's ideas were used as evidence for a wide range of social beliefs, from laissez-faire capitalism to racism, colonialism, and, in perhaps the worst application, Nazism. In the United States, social Darwinism has served as a basis for the creation of IQ tests and for eugenics programs that resulted in the forced sterilization of thousands of mentally ill or retarded Americans. Unsettling Implications: The Growing Gulf Between Science and Religion During the late 19th century, largely through the efforts of scientists who sought to integrate evolutionary science with spiritual belief, evolution was widely accepted by the religious community in the United States. Today, this is hardly the case. In his last four lectures, Professor Larson examines the trends that have, since 1920, widened the gulf between science and religion. These include an increase in fundamentalist Protestantism, the weakening of liberal Protestantism as a counteracting force, and the growing power of a firmly conservative South. In the 1960s, federally funded neo-Darwinian textbooks provoked a conservative backlash. Beginning with the publication of Henry M. Morris's The Genesis Flood, efforts to gain equal time for the teaching of creation science, based on biblical teachings, gathered strength. Rebuffed by the courts, creationism continues to thrive through the increasing numbers of private Christian schools and through home schooling. The growing gulf between science and religion has unsettling implications for our society. Large segments of the American population reject the naturalism of current evolutionary thinking. Nine of 10 Americans believe in spiritual causes for life, with only 10 percent accepting the purely naturalistic explanations espoused by evolution. Strikingly, these statistics are almost exactly the opposite among the scientific community. A Pulitzer Prize-Winning Teacher As both a historian of science and a professor of law, Professor Edward J. Larson brings exceptional qualifications to this subject. His book, Summer for the Gods: The Scopes Trial and America's Continuing Debate Over Science and Religion, won the 1998 Pulitzer Prize in History. His analysis provides an invaluable perspective on the volatile history of what is arguably the single most significant idea of modern times.

    Kasser launches an ambitious and exciting inquiry into what makes science science, using the tools of philosophy to ask: * Why is science so successful? * Is there such a thing as the scientific method? * How do we distinguish science from pseudoscience? * Is science rational, cumulative, and progressive? Focusing his investigation on the vigorous debate over the nature of science that unfolded during the past 100 years, Professor Kasser covers important philosophers such as Karl Popper, W. V. Quine, Thomas Kuhn, Paul Feyerabend, Imre Lakatos, Carl Hempel, Nelson Goodman, and Bas van Fraassen.All of these thinkers responded in one way or another to logical positivism, the dominant movement influencing the philosophy of science during the first half of the 20 th century. Logical positivism attempted to ground science exclusively in what could be known through direct experience and logic.It sounds reasonable, but logical positivism proved to be riddled with serious problems, and its eventual demise is an object lesson in how truly difficult it is—perhaps impossible—to secure the logical foundations of a subject that seems so unassailably logical: science.

    So universal and timeless are its tactics for pursuing a competitive advantage that some of the most notable people in government, sports, and the entertainment world have all quoted from its nearly 2500-year-old pages. These six expertly crafted lectures explore this classic's wisdom for staying nimble in an ever-changing environment and for maximizing reward while minimizing risk remains eternally fresh. As war and business become more mental and less physical, human intellect plays an ever greater role in competition-making Sun Tzu's strategies highly relevant to the information age.Through a precise explanation of the original text and case studies, Professor Wilson examines how the seminal work's model of leadership has been applied-and misapplied-throughout the realms of war, politics, business, and beyond. You'll study the text's historical framework and then delve into the critical calculations that must be made prior to war-what Sun Tzu refers to as knowing the enemy, knowing ourselves.By studying real-world examples, you'll come away understanding the qualities effective commanders must possess and the work's practical implications for outmaneuvering competitors in daily life. By taking this course, you will appreciate Sun Tzu's content on a far deeper level.Disclaimer: The views expressed in this course are those of the professor and do not necessarily reflect the position or policy of the U.S. Navy, the U.S. Department of Defense, or the U.S. government.

    This discovery dramatically reshaped how humans understood their place in the cosmos, and once and for all laid to rest the idea that the Milky Way galaxy was alone in the universe. Six years later, continuing research by Hubble and others forced Albert Einstein to renounce his own cosmic model and finally accept the astonishing fact that the universe was not immobile but instead expanding. The fascinating story of these interwoven discoveries includes battles of will, clever insights, and wrong turns made by the early investigators in this great twentieth-century pursuit. It is a story of science in the making that shows how these discoveries were not the work of a lone genius but the combined efforts of many talented scientists and researchers toiling away behind the scenes. The intriguing characters include Henrietta Leavitt, who discovered the means to measure the vast dimensions of the cosmos . . . Vesto Slipher, the first and unheralded discoverer of the universe’s expansion . . . Georges Lemaître, the Jesuit priest who correctly interpreted Einstein’s theories in relation to the universe . . . Milton Humason, who, with only an eighth-grade education, became a world-renowned expert on galaxy motions . . . and Harlow Shapley, Hubble’s nemesis, whose flawed vision of the universe delayed the discovery of its true nature and startling size for more than a decade.Here is a watershed moment in the history of astronomy, brought about by the exceptional combination of human curiosity, intelligence, and enterprise, and vividly told by acclaimed science writer Marcia Bartusiak.
