From the Space Shuttle training toilet to a crash test of NASA’s new space capsule, Mary Roach takes us on the surreally entertaining trip into the science of life in space and space on Earth.

    In all the annals of the ancient world, few stories are more gripping than those from this era.In the opening lectures, you'll explore the enigma of Alexander, son of a brilliant father, yet always at odds with the man whom he succeeded. You'll trace his early campaigns against the Persians and follow him to Egypt, where he was acclaimed as the son of god. You'll then look at his career after this and find in him a blend of greatness and madness as he strove to replace the Persian empire of the Achaemenid dynasty with a new, mixed ruling class of Macedonians and Persians.From there, you'll delve into the catastrophic period after Alexander's death in 323 B.C., which ushered in a period of catastrophic change as ambitious warlords carved up Alexander's realm into their own separate empires. You'll learn about each of the three kingdoms that resulted: Ptolemaic Egypt, Seleucid Syria, and the Attalid Empire in Asia Minor. Just as important to these lectures are the in-depth discussions of the bounties of Hellenistic culture, which contributed landmark ideas in everything from philosophy (which became more academic), art and architecture (with its excessive, naked emotions), and religion (especially the growing popularity of cult movements). Taken all together, these lectures are an engrossing and riveting journey into ancient history-and the life and times of the man who left an indelible mark on everything that would come after.

    The fascinating tales in The Disappearing Spoon follow carbon, neon, silicon, gold and every single element on the table as they play out their parts in human history, finance, mythology, conflict, the arts, medicine and the lives of the (frequently) mad scientists who discovered them.Why did a little lithium (Li, 3) help cure poet Robert Lowell of his madness? And how did gallium (Ga, 31) become the go-to element for laboratory pranksters? The Disappearing Spoon has the answers, fusing science with the classic lore of invention, investigation, discovery and alchemy, from the big bang through to the end of time.

    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

    Learning all the tongue twisting names, picking favorites based on ferocity, armor, or sheer size. For many kids this love of ‘terrible lizards’ fizzles out at some point between starting and leaving primary school. All those fancy names slowly forgotten, no longer any need for a favorite.For all those child dino fanatics who didn’t grow up to become paleontologists, dinosaurs seem like something out of mythology. They are dragons, pictures in books, abstract, other, extinct.They are at the same time familiar and mysterious. And yet we’re in an age of rapid discovery—new dinosaur species and genera are being discovered at an accelerating rate, we’re learning more about what they looked like, how they lived, how they evolved and where they all went.This series isn’t just a top trumps list of dino facts—we’re interested in the why and the how and like all areas of science there is plenty of controversy and debate.

    Extremely elusive and difficult to pin down, neutrinos are not unlike the brilliant and eccentric scientists who doggedly pursue them.In Neutrino Hunters, the renowned astrophysicist and award-winning writer Ray Jayawardhana takes us on a thrilling journey into the shadowy world of neutrinos and the colorful lives of those who seek them. Demystifying particle science along the way, Jayawardhana tells a detective story with cosmic implications—interweaving tales of the sharp-witted theorist Wolfgang Pauli; the troubled genius Ettore Majorana; the harbinger of the atomic age Enrico Fermi; the notorious Cold War defector Bruno Pontecorvo; and the dynamic dream team of Marie and Pierre Curie. Then there are the scientists of today who have caught the neutrino bug, and whose experimental investigations stretch from a working nickel mine in Ontario to a long tunnel through a mountain in central Italy, from a nuclear waste site in New Mexico to a bay on the South China Sea, and from Olympic-size pools deep underground to a gigantic cube of Antarctic ice—called, naturally, IceCube.As Jayawardhana recounts a captivating saga of scientific discovery and celebrates a glorious human quest, he reveals why the next decade of neutrino hunting will redefine how we think about physics, cosmology, and our lives on Earth.

    Biographer and broadcaster Lucinda Hawksley gains unprecedented access to a treasure trove of Doyle’s never-before-seen personal letters and diaries. This is a chance for Sherlock fans to see their detective hero and his creator as they’ve never seen them before. Through interviews with Doyle aficionados, academics, actors and family members, we explore Doyle’s travels and sailing adventures across the globe, his pioneering work as a doctor, his life in the Freemasons and his fights against miscarriages of justice. As well as his many triumphs, we will also explore the challenges he faced, from the death of his first wife and son to the initial rejection he faced as an author. We will also look beyond Sherlock to Doyle’s other great works including his fantasy and science fiction novels and hear how one of his most famous, The Lost World, part-inspired Michael Crichton’s book of the same name, which became the successful Jurassic Park film franchise.

    The general theory of relativity describes the behavior of very large things, and quantum theory the behavior of very small things. In this landmark book, John Gribbin—one of the best-known science writers of the past thirty years—presents his own version of the Holy Grail of physics, the search that has been going on for decades to find a unified “Theory of Everything” that combines these ideas into one mathematical package, a single equation that could be printed on a T-shirt, containing the answer to life, the Universe, and everything. With his inimitable mixture of science, history, and biography, Gribbin shows how—despite skepticism among many physicists—these two great theories are very compatible, and point to a deep truth about the nature of our existence. The answer lies, intriguingly, with the age of the universe: 13.8 billion years.

    There are thousands of books on the subject, as well as a multitude of websites. Much has also been written on the science of child development. What's been lacking, however, are sources of reliable advice that bring together the scientific research and its real-world applications. This course bridges the divide. In 24 engaging lectures, an expert in the cognitive development of early childhood presents what scientific research has revealed about the things parents can actively do to promote children’s long-term development right from birth. Professor Vishton delivers a wealth of practical tips to help children reach their full potential intellectually, emotionally, physically, and socially. And he supports it all with findings culled from the latest scientific literature. You’ll touch on topics across all areas of childrearing, from sleep and nutrition to behavior and academics. And you’ll get answers to many of the most common parenting questions: Should I sleep-train my baby by letting her “cry it out”? Should I let my infant, toddler, or child watch TV-and if so, how much? Should I allow my child to play video games? Should I pressure my picky eater to finish her vegetables? Should I spank my child when he misbehaves? In addition to learning methods for laying an early foundation in subjects such as math and reading, you’ll gain information for boosting your children’s overall cognitive abilities-and even their IQ scores.

    There are deep connections between stars and atoms, between the cosmos and the microworld. Just six numbers, imprinted in the "big bang," determine the essential features of our entire physical world. Moreover, cosmic evolution is astonishingly sensitive to the values of these numbers. If any one of them were "untuned," there could be no stars and no life. This realization offers a radically new perspective on our universe, our place in it, and the nature of physical laws.

    Professor Hans-Friedrich Mueller, of Union College in Schenectady, New York, makes this ancient world come alive in 24 lectures with captivating stories of intrigue, artifacts, illustrations, and detailed descriptions from primary sources of intriguing personalities. In the ancient Mediterranean area, religion was not separate from daily life. To the contrary, religion was daily life. The many dozen gods of this ancient world were everywhere, with spirits inhabiting every crack and crevice of life. These polytheists believed they had a strict contract with their deities: If they took care of their gods, their gods would take care of them (or at least not harm them). Consequently, they built extraordinary temples to honor their deities, brought food and wine to them, sacrificed animals for them, and held sacred meals with their gods. In fact, they followed numerous rules and regulations that circumscribed almost all aspects of life both inside and outside the home - anything and everything to keep the gods happy. Consequently, the religious practices of the ancient Mediterranean make a wonderful lens through which to develop a deeper understanding of their world.

    Classic stories and poems of American literature are found in the pages of Franklin, Emerson, Thoreau, Hawthorne, Melville, Dickinson, Twain, Whitman, Faulkner, James, Eliot, Fitzgerald, Hemingway, Steinbeck, Morrison, and many others. As Professor Arnold Weinstein reminds us: "American classics are wonderfully rich fare. America is a mythic land, a place with a sense of its own destiny and promise, a place that has experienced bloody wars to achieve that destiny. The events of American history shine forth in our classics." When was the last time you read them? Possibly not as recently as you'd like. Why? Not because you wouldn't love it. But perhaps the demands of your daily life or some other reason have prevented this pleasure. Now, here is the opportunity to gain an extraordinary familiarity with each of these authors within a manageable amount of time, as well as review the great works you may already know. What Explains Greatness? These works are both American and classics. The course has been crafted to explain why some works become classics while others do not, why some "immortal" works fade from our attention completely, and even why some contemporary works now being ignored or snubbed by critics may be considered immortal one day. One memorable work at a time, you'll see how each of these masterpieces shares the uncompromising uniqueness that invariably marks the entire American literary canon. From Sleepy Hollow to The Great Gatsby, Professor Weinstein contends that the literary canon lives, grows, and changes. What links these writers to each other—and to us readers today—is the awareness that the past lives and changes as generations of writers and readers step forward to interpret it anew. The course was born from Professor Weinstein's conviction that American literature is our "great estate," and that claiming this rightful inheritance—the living past and the lessons we can take from it—should be nothing less than a unique and joyous learning experience. Experience Two Centuries of America's Greatest Works Professor Weinstein explains that America's classic works should be savored as part of our inner landscape: part of how we see both America and ourselves. He leads you through more than two centuries of the best writers America has yet produced, bringing out the beauty of their language, the excitement of their stories, and the value in what they say about life, power, love, adventure, and what it means, in every sense, to be American. Perhaps you recall: --Melville's prowling Ahab, on the search for Moby Dick, and the power of the "grand, ungodly, Godlike man" --The quiet diner in The Grapes of Wrath and the pain of one of John Steinbeck's "Okies" trying to purchase a dime's worth of bread. --The parlor in Long Day's Journey Into Night and the lifetime of tension in a simple request to a father that he turn on the lights. Rip Van Winkle falls asleep for 25 years for some mysterious reason—but what exactly was it? Why did Emerson believe in self-reliance, and why do we? Twain, our first media celebrity, tells stories that have an inkling of Peter Pan: Tom Sawyer never does grow up. But Huck Finn must grow up to face the racism of the South and get past his own polluted conscience—can he do it? James brings American innocents to Europe for them to inherit the world—but do they? Discover the Stories behind America's Immortal Writers Consider that: --Emily Dickinson was virtually unheard of in her own time. --William Faulkner's books were out of print until the mid-1940s. --F. Scott Fitzgerald died believing he had been forgotten. Readers of their times would be astounded if they knew the immortality these writers achieved, just as we are astounded that they once were overlooked. Most of us don't know that when Walt Whitman self-published Leaves of Grass—seemingly in answer to Ralph Waldo Emerson's memorable wish for the poet America deserved—he sent a copy to Emerson, America's most revered man of letters. When Emerson replied in extraordinarily flattering terms, Whitman published his letter, virtually forcing the new poet's acceptance by a literati that would might have preferred to flee from Whitman's startlingly new, often sexual, poetry. Perhaps you share the common picture of Emily Dickinson: a passive, gentle, reclusive spinster content in her father's Amherst, Massachusetts, home. If so, allow Professor Weinstein to introduce you to her friend, clergyman and author Thomas Wentworth Higginson, who said of "gentle" Emily: "I never was with anyone who drained my nerve power so much. Without touching her, she drew from me. I am glad not to live near her." Through this course, you will learn to: --Explain the roles of self-reliance and the "self-made man" in the evolution of American literature --Identify the tenets of American Romanticism --Describe the evolution of the American ghost story, from Poe and Hawthorne to James and Morrison --Outline the epic strain in American literature, from Melville and Whitman to Faulkner and Ellison --Explain the importance of slavery as a critical subject for Stowe, Twain, Faulkner, and Morrison --Summarize perspectives on nature revealed in poets Whitman, Dickinson, Frost, and Eliot --Identify the tenets of Modernism in the work of Eliot, Fitzgerald, Hemingway, and Faulkner --Identify the contributions of O'Neill, Miller, and Williams to American theater --Summarize the threads of the complex relationship between America's great writers and the past. Savor the Joy of Great ReadingDr. Weinstein is the Edna and Richard Salomon Distinguished Professor at Brown University, where he has been teaching literature to packed classrooms since 1968. Brown University student course evaluation summaries reported: "By far, students' greatest lament was that they only got to listen to Professor Weinstein once a week." One customer writes: "Professor Weinstein is inspiring. Not only am I enjoying these lectures, but I am also rereading these wonderful classics and having a wonderful time." The course will lead you to read or reread masterpieces that intrigue you most. And with the deeper understanding you gain from the lectures, you will likely experience such joy from great reading that you may wonder why you have spent so much time on contemporary books. The 84 carefully crafted lectures in this course, each 30 minutes long, are your royal road to recapturing the American experience—and our intellectual and cultural heritage. Just review the lecture titles. All of this can be yours, and the journey will be as rewarding as the arrival.

    Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past. Impey uses this concept—"look-back time"—to take us on an intergalactic tour that is simultaneously out in space and back in time. Performing a type of cosmic archaeology, Impey brilliantly describes the astronomical clues that scientists have used to solve fascinating mysteries about the origins and development of our universe.The milestones on this journey range from the nearby to the remote: we travel from the Moon, Jupiter, and the black hole at the heart of our galaxy all the way to the first star, the first ray of light, and even the strange, roiling conditions of the infant universe, an intense and volatile environment in which matter was created from pure energy. Impey gives us breathtaking visual descriptions and also explains what each landmark can reveal about the universe and its history. His lucid, wonderfully engaging scientific discussions bring us to the brink of modern cosmology and physics, illuminating such mind-bending concepts as invisible dimensions, timelessness, and multiple universes.A dynamic and unforgettable portrait of the cosmos, How It Began will reward its readers with a deeper understanding of the universe we inhabit as well as a renewed sense of wonder at its beauty and mystery.

    Powerful women have shaped laws, led rebellions, and played key roles in dynastic struggles. Some were caught up in forces beyond their control, while others manipulated and murdered their way to the top. However, unearthing their stories from the historical record has been a challenge, with the ordinary difficulties of preserving information across the generations increased by centuries of historical bias and gendered expectations. Women, when they were mentioned at all, often filled the role of virtuous maiden, self-effacing mother, or seductive villain. Imagine what you are missing when only half the story is being told.  In Warriors, Queens, and Intellectuals: 36 Great Women Before 1400, taught by Professor Emerita of Humanistic Studies Joyce E. Salisbury, you will experience another side of history, one that has often been overlooked. In these 36 lectures, women step out from the footnotes and sidebars of traditional history and into the spotlight, illuminating the dark corners of the pre-modern world along the way. From thwarted daughters and ambitious wives to fearless revolutionaries and brilliant philosophers, you will see how women have played diverse roles throughout history and why their influence is so vital to a fuller understanding of the world we live in today. Beginning at the start of the Roman Empire and carrying you through to the end of the Middle Ages, Professor Salisbury will introduce you to dozens of influential women from all across the globe.
