Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.

    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.

    Charting the most cutting-edge scientific breakthroughs, and marshalling his decades of research and clinical practice, Walker explains how we can harness sleep to improve learning, mood and energy levels, regulate hormones, prevent cancer, Alzheimer's and diabetes, slow the effects of aging, and increase longevity. He also provides actionable steps towards getting a better night's sleep every night.

    Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    It is the history of who you are and how you came to be. It is unique to you, as it is to each of the 100 billion modern humans who have ever drawn breath. But it is also our collective story, because in every one of our genomes we each carry the history of our species births, deaths, disease, war, famine, migration, and a lot of sex. Since scientists first read the human genome in 2001, it has been subject to all sorts of claims, counterclaims, and myths. In fact, as Adam Rutherford explains, our genomes should be read not as instruction manuals, but as epic poems. DNA determines far less than we have been led to believe about us as individuals, but vastly more about us as a species. In this captivating journey through the expanding landscape of genetics, Adam Rutherford reveals what our genes now tell us about history, and what history tells us about our genes. From Neanderthals to murder, from redheads to race, dead kings to plague, evolution to epigenetics, this is a demystifying and illuminating new portrait of who we are and how we came to be."

    From body lotion to tonic water, the popular new element shines bright in the otherwise dark years of the First World War.Meanwhile, hundreds of girls toil amidst the glowing dust of the radium-dial factories. The glittering chemical covers their bodies from head to toe; they light up the night like industrious fireflies. With such a coveted job, these "shining girls" are the luckiest alive—until they begin to fall mysteriously ill.But the factories that once offered golden opportunities are now ignoring all claims of the gruesome side effects, and the women's cries of corruption. And as the fatal poison of the radium takes hold, the brave shining girls find themselves embroiled in one of the biggest scandals of America's early 20th century, and in a groundbreaking battle for workers' rights that will echo for centuries to come.Written with a sparkling voice and breakneck pace, The Radium Girls fully illuminates the inspiring young women exposed to the "wonder" substance of radium, and their awe-inspiring strength in the face of almost impossible circumstances. Their courage and tenacity led to life-changing regulations, research into nuclear bombing, and ultimately saved hundreds of thousands of lives.

    Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live. Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life. Now, from one of the world's foremost researchers on stress and neurobiology, comes a fascinating series of 24 lectures that guide you through the psychological and psychosocial stress that is a central part of everyday life in Western society. You'll learn how the stress-response system is actually a natural survival system-giving, for example, a zebra the best chance to escape from a pursuing lion - that can change from a safety mechanism into a real problem for our physical and mental well-being. You'll see it coming into play against situations it wasn't designed to combat, such as traffic, troublesome thoughts and memories, and concerns over the economy, environment, and international events. And you'll gain valuable insights into how and why stress can affect every part of your body-including your cardiovascular, digestive, and immune systems - and learn about its relationship to important disorders and behaviors, like depression, anxiety, and even addiction.

    But now, with revolutionary medical advances, death has become just another serious complication. As a young medical student, Dr. David Casarett was inspired by the story of a two-year-old girl named Michelle Funk. Michelle fell into a creek and was underwater for over an hour. When she was found she wasn’t breathing, and her pupils were fixed and dilated. That drowning should have been fatal. But after three hours of persistent work, a team of doctors and nurses was able to bring her back. It was a miracle. If Michelle could come back after three hours of being dead, what about twelve hours? Or twenty-four? What would it take to revive someone who had been frozen for one thousand years? And what does blurring the line between “life” and “death” mean for society? In Shocked, Casarett chronicles his exploration of the cutting edge of resuscitation and reveals just how far science has come. He begins in the eighteenth century, when early attempts at resuscitation involved public displays of barrel rolling, horseback riding (sort of), and blowing smoke up the patient’s various orifices. He then takes us inside a sophisticated cryonics facility in the Arizona desert, a darkroom full of hibernating lemurs in North Carolina, and a laboratory that puts mice into a state of suspended animation. The result is a spectacular tour of the bizarre world of doctors, engineers, animal biologists, and cryogenics enthusiasts trying to bring the recently dead back to life. Fascinating, thought-provoking, and (believe it or not) funny, Shocked is perfect for those looking for a prequel—and a sequel—to Mary Roach’s Stiff, or for anyone who likes to ponder the ultimate questions of life and death.

    This is a world tour of prehistory with profound links to who we are and how we live today.2.5 Million Years of HistoryThis 36-lecture narrative covers human prehistory from our beginnings more than 2.5 million years ago up to and beyond the advent of the world's first preindustrial civilizations.Due to the large spans of time and geography covered in this series, these lectures are divided into six sections:Section I: BeginningsThis section surveys the archaic world of the first humans, you travel into the remote past, learning why the late Harvard biologist Stephen Jay Gould was probably right to observe that we all come from the same African twig on the bushy tree of human evolution.You examine prehistory from Australopithecus africanus through Homo habilis (the first tool-making hominid), and Homo erectus (whose remains were first found on Java but whose origins lie in Africa) through the hardy Neanderthals who lived and hunted successfully in Europe despite the bitter grip of the last Ice Age 100,000 and more years ago. You focus on the first human settlement of Africa as early as 800,000 years ago.Section II: Modern HumansThis section tells the story of the great diaspora of anatomically modern humans in the late Ice Age. Whether and how these modern humans spread from the African tropics into southwestern Asia and beyond remains one of the great controversies among scholars of prehistory.You follow Homo sapiens sapiens north into Europe some 45,000 years ago. You meet the Cro-Magnons, among the first known artists as well as hunter-gatherers, who exhibited degrees of spiritual awareness, social interaction, and fluid intelligence.You venture into the frigid open plains of the Ukraine and Eurasia, where big-game hunters flourished in spite of nine-month winters. Moving to the Americas, debate over the origins of the first human settlement continues.Section III: Farmers and HerdersThis section describes perhaps the most important development in all human prehistory: the beginnings of agriculture and animal domestication.This defining chapter began about 12,000 years ago, when hunter-gatherers in the Near East broke from the long human tradition of intensely mobile foraging and turned to more settled ways of life built around cultivating cereal grains or tending animals.Section IV: Eastern Mediterranean CivilizationsProfessor Fagan describes early civilizations in an increasingly complex eastern Mediterranean world, discussing many theories accounting for the appearance of urban civilization and overall attributes of preindustrial civilizations.You examine Sumerian civilization in Mesopotamia and the intricate patchwork of city-states between the Tigris and Euphrates Rivers. You explore ancient Egypt, the Minoan civilization of Crete, the Mycenaeans, and the Hittites.You learn about the Uluburun shipwreck of southern Turkey, a sealed capsule of international trade from 3,000 years ago.Section V: Africans and AsiansYou analyze the beginnings of South Asian civilization and the mysterious Harappan civilization of the Indus, which traded with Mesopotamia. Professor Fagan resumes the story of South Asian civilization after the collapse of the Harappan and shows how Mauryan rulers on the Ganges encouraged trading much farther afield.You see the impact of monsoons which revolutionized maritime trading among Africa, India, and Southeast Asia, and explore Meroe, Aksum, and the coastal civilization of East Africa.Several lectures cover the beginnings of civilization in China and Southeast Asia.Section VI: Ancient AmericansProfessor Fagan takes you into sophisticated chiefdoms and civilizations that developed in the Americas over the past 3,500 years, including Pueblo cultures of the North American Southwest and the Mississippian culture of the South and Southeast. You learn about Mesoamerican civilization, primordial Olmec culture of the lowlands, and the spectacular ancient Maya civilization.Moving to the highlands, you visit the city-states of Monte Albán in the Valley of Oaxaca and Teotihuacán near the Valley of Mexico. Professor Fagan also describes the rise of Aztec civilization, followed by a journey to the Andes. Finally, you explore the southern highlands, with the rise of Tiwanaku near Lake Titicaca, the Chimu civilization of the coast, and the huge Inka empire.The series closes by analyzing the closing centuries of prehistoric times during the European age of discovery and summarizing the main issues and themes of the course: * What was involved in the archaic world * The appearance and spread of modern humans * Food production * The development of states.

    Urzila talks candidly about her childhood with a great family, apart from her abusive dad, and about growing up in South Africa. She shares crazy but true tales about her OE, her move to New Zealand, coming out, getting married and having children, and her life in comedy. This is a great listen from one of our most loved and most popular comedians.

    But the Black Death was arguably the most significant event in Western history, profoundly affecting every aspect of human life, from the economic and social to the political, religious, and cultural. In its wake the plague left a world that was utterly changed, forever altering the traditional structure of European societies and forcing a rethinking of every single system of Western civilization: food production and trade, the church, political institutions, law, art, and more. In large measure, by the profundity of the changes it brought, the Black Death produced the modern world we live in today.While the story of the Black Death is one of destruction and loss, its breathtaking scope and effects make it one of the most compelling and deeply intriguing episodes in human history. Understanding the remarkable unfolding of the plague and its aftermath provides a highly revealing window not only on the medieval world but also on the forces that brought about the Renaissance, the Protestant Reformation, and modernity itself.Speaking to the full magnitude of this world-changing historical moment, The Black Death: The World's Most Devastating Plague, taught by celebrated medievalist Dorsey Armstrong of Purdue University, takes you on an unforgettable excursion into the time period of the plague, its full human repercussions, and its transformative effects on European civilization. In 24 richly absorbing lectures, you'll follow the path of the epidemic in its complete trajectory across medieval Europe. Majestic in scope and remarkable in detail, this course goes to the heart of one of Western history's most catalytic and galvanizing moments, the effects of which gave us the modern world.

    It lasted 3,000 years, longer than any other on the planet. Its Great Pyramid of Cheops was the tallest building in the world until well into the 19th century and remains the only Ancient Wonder still standing. And it was the most technologically advanced of the ancient civilizations, with the medical knowledge that made Egyptian physicians the most famous in the world.Yet even after deciphering its hieroglyphs, and marveling at its scarabs, mummies, obelisks, and sphinxes, Egyptian civilization remains one of history's most mysterious, as "other" as it is extraordinary. This chronological survey presents the complete history of ancient Egypt's three great Kingdoms: the Old Kingdom, when the pyramids were built and Egypt became a nation under the supreme rule of the pharaoh and the rules of Egyptian art were established; the Middle Kingdom, when Egypt was a nation fighting to restore its greatness; and the New Kingdom, when all the names we know today-Hatshepsut, Tutankhamen, Ramses the Great, Cleopatra, and others-first appeared.Listening Length: 24 hours and 25 minutes

    These are today's sins of science—as deplorable as mistaken past ideas about advocating racial purity or using lobotomies as a cure for mental illness. These unwitting errors add up to seven lessons both cautionary and profound, narrated by renowned author and speaker Paul A. Offit. Offit uses these lessons to investigate how we can separate good science from bad, using some of today's most controversial creations—e-cigarettes, GMOs, drug treatments for ADHD—as case studies. For every "Aha!" moment that should have been an "Oh no," this book is an engrossing account of how science has been misused disastrously—and how we can learn to use its power for good.
