This ancient civilization prospered in the region of modern-day Tuscany, maintaining extensive trade networks, building impressive fortified cities, making exquisite art, and creating a culture that, while deeply connected to the Greeks and Romans, had striking contrasts.

    Take an adventurous trek to these wilds of South America and the great civilizations of the ancients. In 24 eye-opening lectures, you'll take an in-depth look at the emerging finds and archaeological knowledge of more than 12 seminal civilizations, giving you rich insight into the creative vision and monumental achievements of these wellsprings of human life. The ancient South Americans show us striking models of how societies can function and organize themselves. The technologies and social structures seen here were wholly invented, using no preexisting models, as these dynamic peoples struggled to tame their environment and carve out societies and empires. Recently unearthed marvels include elaborately prepared and adorned mummies that predate Egypt's by 2000 years; imposing palaces, solar observatories, and dramatically decorated pyramids; stunning art objects in gold, turquoise, lapis lazuli, and ceramic; and evidence of huge urban civilizations in the Amazon. In their amazing sophistication and scale, the sites reveal some of the most remarkable ancient artifacts found anywhere in the world. The breathtaking valleys, mountains, and deserts you will study in this course reveal wonders that rival anything we know of the ancient world. Travel with us to a lost and splendorous past - a fountainhead of civilization that speaks unforgettably of human striving, vision, and the indomitable will to endure.Listening Length: 11 hours and 54 minutes

    Ultimately, the history of these challenges tells the story of humanity itself. Through an unforgettable cast of characters, Pulitzer Prize-winning author Richard Rhodes explains how wood gave way to coal and coal made room for oil, as we now turn to natural gas, nuclear power, and renewable energy. Rhodes looks back on five centuries of progress, through such influential figures as Queen Elizabeth I, King James I, Benjamin Franklin, Herman Melville, John D. Rockefeller, and Henry Ford. In Energy, Rhodes highlights the successes and failures that led to each breakthrough in energy production; from animal and waterpower to the steam engine, from internal-combustion to the electric motor. He addresses how we learned from such challenges, mastered their transitions, and capitalized on their opportunities. Rhodes also looks at the current energy landscape, with a focus on how wind energy is competing for dominance with cast supplies of coal and natural gas. He also addresses the specter of global warming, and a population hurtling towards ten billion by 2100. Human beings have confronted the problem of how to draw life from raw material since the beginning of time. Each invention, each discovery, each adaptation brought further challenges, and through such transformations, we arrived at where we are today. In Rhodes’s singular style, Energy details how this knowledge of our history can inform our way tomorrow.

    The effects of homeopathy don’t go away under rigorous scientific conditions. The laws of nature aren’t what they used to be. Thirty years on, no one has an explanation for a seemingly intelligent signal received from outer space. The US Department of Energy is re-examining cold fusion because the experimental evidence seems too solid to ignore. The placebo effect is put to work in medicine while doctors can’t agree whether it even exists.In an age when science is supposed to be king, scientists are beset by experimental results they simply can’t explain. But, if the past is anything to go by, these anomalies contain the seeds of future revolutions. While taking readers on an entertaining tour d’horizon of the strangest of scientific findings – involving everything from our lack of free will to Martian methane that offers new evidence of life on the planet – Michael Brooks argues that the things we don’t understand are the key to what we are about to discover.This mind-boggling but entirely accessible survey of the outer limits of human knowledge is based on a short article by Michael Brooks for New Scientist magazine. It became the sixth most circulated story on the internet in 2005, and provoked widespread comment and compliments (Google “13 things that do not make sense” to see).Michael Brooks has now dug deeply into those mysteries, with extraordinary results.

    Eakin of Vanderbilt University argues that it gave birth to the distinct identity of the Americas today by creating a collision between three distinct peoples and cultures: European, African, and Native American. (24 lectures, 30 minutes/lecture)

    Each professor addresses an area of personal expertise and focuses not only on the matter at hand, but on the larger story-on the links between the works and the figures discussed. The lectures address-in chronological sequence-a series of major works that have shaped the ongoing development of Western thought both in their own right and in cultural dialogue with other traditions. In the process, the course engages many of the most perennial and far-reaching questions that we face in our daily lives.Lecture 1 From Sumer to AthensLecture 2 The Epic of GilgameshLecture 3 The Hebrew Bible: Historical Background and GenesisLecture 4 The Hebrew Bible: Exodus and the CovenantLecture 5 The Hebrew Bible: Psalms, Prophets, The Song of Songs, and JobLecture 6 Greece: From the Bronze Age to the Archaic AgeLecture 7 The IliadLecture 8 Homer: The OdysseyLecture 9 Hesiod and Lyric PoetryLecture 10 Greek Tragedy: AeschylusLecture 11 Greek Tragedy: SophoclesLecture 12 Greek Tragedy: EuripidesLecture 13 Herodotus of HalicarnassusLecture 14 Greek Art

    Robinson Crusoe. Harry Potter. What do these memorable characters have in common? Why do we turn to certain stories again and again? And what impact have they made on world history? These 24 eye-opening lectures give fresh insight into some of the greatest heroes in world literature, from warriors such as Beowulf and Odysseus to unexpected heroes such as Uncle Tom and Sancho Panza.Professor Shippey gives you an inside glimpse into the writer's process. Learn how authors "write into the gap" to flesh out-or, in some cases, reimagine altogether-old stories, making them new for new readerships with different values. By examining what makes these heroes such compelling characters, you'll see how they provide a window to better understand ourselves.From the beginnings of world literature through today's bestsellers, look at what makes characters successful-and how they reflect our changing cultural mores. For instance, after the horrors of global war in the 20th century, the world was waiting for a hero like Frodo Baggins, J.R.R. Tolkien's meek hobbit hero, someone called to duty rather than born strong and fearless.You'll also examine ways that great heroes have changed the course of history, defining nations and redefining our sense of self and our relationships. From the mythical journey of Aeneas to Jane Austen's country dances, you'll survey a wealth of memorable stories and consider why such heroes were necessary-and how they continue to influence our lives today.

    Beginning with the above questions, she began informally researching every affliction that she encountered in humans to learn whether it happened with animals, too. And usually, it did: dinosaurs suffered from brain cancer, koalas can catch chlamydia, reindeer seek narcotic escape in hallucinogenic mushrooms, stallions self-mutilate, and gorillas experience clinical depression. Natterson-Horowitz and science writer Kathryn Bowers have dubbed this pan-species approach to medicine zoobiquity. Here, they present a revelatory understanding of what animals can teach us about the human body and mind, exploring how animal and human commonality can be used to diagnose, treat, and heal patients of all species.

    A leather couch. A neatly bearded, scholarly looking gentleman seated off to the side, only rarely speaking, quietly taking notes and occasionally nodding as the couch's supine occupant tells his or her story.In some ways, such a picture would indeed be accurate, a confirmation not only of the importance of Sigmund Freud in the history of psychology but also of the degree Freud dominates the popular perception of this discipline.But the picture would be inaccurate, as well.Freud was a physician, and the majority of psychologists are not. Both the psychoanalytic theory he pioneered and the therapeutic approach it was based onpsychoanalysishave seen their dominance wane in recent years. And psychologists today, as indebted as they may be to Freud's landmark explorations of our psychological landscape, are involved in far more than helping people cope with inner demons.The expansive and varied roles of contemporary psychologists create another common imageof a crowd of white-coated researchers gathered around a maze, carefully recording a white rat's performance. It's another inadequate picture because experimental psychologists today usually work with people, not animals.Moreover, the areas of interest those psychologists are pursuing now encompass every part of the process we use to develop and function as people:How we perceive, remember, and learnHow we select our friends and partners and retain their affection and loveThe things that motivate us as we make our choices in lifeEven how we relate to the vehicles, machinery, computer systems, or workspaces we encounter as we make our livings.

    From Edward Lorenz’s discovery of the Butterfly Effect, to Mitchell Feigenbaum’s calculation of a universal constant, to Benoit Mandelbrot’s concept of fractals, which created a new geometry of nature, Gleick’s engaging narrative focuses on the key figures whose genius converged to chart an innovative direction for science. In Chaos, Gleick makes the story of chaos theory not only fascinating but also accessible to beginners, and opens our eyes to a surprising new view of the universe.

    November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.

    The Cave and the Light is a magisterial account of how the two greatest thinkers of the ancient world, Plato and Aristotle, laid the foundations of Western culture—and how their rivalry shaped the essential features of our culture down to the present day.   Plato came from a wealthy, connected Athenian family and lived a comfortable upper-class lifestyle until he met an odd little man named Socrates, who showed him a new world of ideas and ideals. Socrates taught Plato that a man must use reason to attain wisdom, and that the life of a lover of wisdom, a philosopher, was the pinnacle of achievement. Plato dedicated himself to living that ideal and went on to create a school, his famed Academy, to teach others the path to enlightenment through contemplation.   However, the same Academy that spread Plato’s teachings also fostered his greatest rival. Born to a family of Greek physicians, Aristotle had learned early on the value of observation and hands-on experience. Rather than rely on pure contemplation, he insisted that the truest path to knowledge is through empirical discovery and exploration of the world around us. Aristotle, Plato’s most brilliant pupil, thus settled on a philosophy very different from his instructor’s and launched a rivalry with profound effects on Western culture.   The two men disagreed on the fundamental purpose of the philosophy. For Plato, the image of the cave summed up man’s destined path, emerging from the darkness of material existence to the light of a higher and more spiritual truth. Aristotle thought otherwise. Instead of rising above mundane reality, he insisted, the philosopher’s job is to explain how the real world works, and how we can find our place in it. Aristotle set up a school in Athens to rival Plato’s Academy: the Lyceum. The competition that ensued between the two schools, and between Plato and Aristotle, set the world on an intellectual adventure that lasted through the Middle Ages and Renaissance and that still continues today.   From Martin Luther (who named Aristotle the third great enemy of true religion, after the devil and the Pope) to Karl Marx (whose utopian views rival Plato’s), heroes and villains of history have been inspired and incensed by these two master philosophers—but never outside their influence.   Accessible, riveting, and eloquently written, The Cave and the Light provides a stunning new perspective on the Western world, certain to open eyes and stir debate.Praise for The Cave and the Light   “A sweeping intellectual history viewed through two ancient Greek lenses . . . breezy and enthusiastic but resting on a sturdy rock of research.”—Kirkus Reviews   “Examining mathematics, politics, theology, and architecture, the book demonstrates the continuing relevance of the ancient world.”—Publishers Weekly  “A fabulous way to understand over two millennia of history, all in one book.”—Library Journal  “Entertaining and often illuminating.”—The Wall Street JournalFrom the Hardcover edition.

    Kennedy astonished the world on May 25, 1961, when he announced to Congress that the United States should land a man on the Moon by 1970. No group was more surprised than the scientists and engineers at NASA, who suddenly had less than a decade to invent space travel. When Kennedy announced that goal, no one knew how to navigate to the Moon. No one knew how to build a rocket big enough to reach the Moon, or how to build a computer small enough (and powerful enough) to fly a spaceship there. No one knew what the surface of the Moon was like, or what astronauts could eat as they flew there. On the day of Kennedy’s historic speech, America had a total of fifteen minutes of spaceflight experience—with just five of those minutes outside the atmosphere. Russian dogs had more time in space than U.S. astronauts. Over the next decade, more than 400,000 scientists, engineers, and factory workers would send 24 astronauts to the Moon. Each hour of space flight would require one million hours of work back on Earth to get America to the Moon on July 20, 1969. More than fifty years later, One Giant Leap is the sweeping, definitive behind-the-scenes account of the furious race to complete one of mankind’s greatest achievements. It’s a story filled with surprises—from the item the astronauts almost forgot to take with them (the American flag), to the extraordinary impact Apollo would have back on Earth, and on the way we live today. Charles Fishman introduces readers to the men and women who had to solve 10,000 problems before astronauts could reach the Moon. From the research labs of MIT, where the eccentric and legendary pioneer Charles Draper created the tools to fly the Apollo spaceships, to the factories where dozens of women sewed spacesuits, parachutes, and even computer hardware by hand, Fishman captures the exceptional feats of these ordinary Americans. One Giant Leap is the captivating story of men and women charged with changing the world as we knew it—their leaders, their triumphs, their near disasters, all of which led to arguably the greatest success story, and the greatest adventure story, of the twentieth century.
