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

    There's an elderly man complaining of chest pain, a teenage girl whose arms are swollen with bee stings, and an ambulance bringing in two unresponsive kids from a car crash. What do you do next?In Dr. Benaroch's 24 lectures, experience for yourself the high-stakes drama and medical insights of life in an everyday emergency department: the most intense department in any hospital and home to the kind of split-second decision making, troubleshooting, and detective work that can make the difference between a patient's life and death.Every lecture brings you up close and personal with the common and uncommon medical crises that emergency doctors encounter throughout their careers. As you shadow Dr. Benaroch on his shifts and sometimes even venture off-site, you'll encounter patients coming in with a variety of symptoms and complaints - some of which are easily diagnosed and treated and some of which are more life-threatening than they first appear. At the heart of each case are powerful examples of:How emergency doctors think on their feetHow emergency doctors determine what's really wrong with a patientHow emergency doctors rule in - or out - certain diagnosesHow emergency doctors counsel patients and families on improving healthThis is your opportunity to explore the adventure, mystery, and fascination of emergency medicine - and to discover why it's one of the most exciting and rewarding branches of medicine to work in.

    Whether it's something as minor as a brush with the common cold or as serious as Ebola, we all have grappled with infections and will continue to encounter them as we age.On a worldwide scale, infectious diseases account for 26 percent of all deaths, second only to cardiovascular diseases. And unlike chronic diseases, infectious diseases are unique in their potential for explosive global impacts.Now, in the 24 engaging lectures of Introduction to Infectious Diseases, you can get a comprehensive overview of diseases from the mundane to the fatal from renowned physician and award-winning professor Dr. Barry Fox.Begin with an overview of the microscopic particles responsible for disease: bacteria, fungi, hybrid germs, and viruses. You will see how they invade the body; look through the microscope at pathogens to identify their inner components; follow germs through to different body systems and see what effects they have; and learn why we may be losing the battle against some germs.

    One such change was the Agricultural Revolution, with the domestication of plants and animals and a shift in survival strategies from hunting and gathering to farming and animal husbandry. Simultaneous with that was the Urban Revolution, the founding of cities. We discuss the current thinking on these revolutions in human existence and their relationship. Much of that discussion takes place in the context of the earliest city, ?atalh?y?k, and a second Neolithic foundation, Jericho. Both of these also provide material to explore the role of religion in the very earliest communities, to ask its role in city formation, and to explore the place of religious structures in city identity. Burial practices at the two cities also illuminate early ideas of property ownership and the definition of the family home.In the Bronze Age, cities grew most rapidly in civilizations founded in the great river valleys, from the Nile in Egypt, to the Euphrates in Mesopotamia, to the Indus in modern Pakistan and India. In these cities made of mud, we can trace elements of domestic life and civic spaces. Three of the cities, Mohenjo-daro in the Indus Valley and Kahun and Deir el-Medina in Egypt, have no recognizable public buildings. Yet the reasons for that negative evidence for civic life differ wildly, as do the structures of these societies. At Deir el-Medina, we encounter some of the oldest conclusive evidence for private enterprise in an ancient city. We also begin to see how social organization is reflected in city formation. The Sumerian city of Uruk, the first megacity in world history, provides the model for the monumentalization of religious structures and their integration in the civic space and government of the city. Finally, in the last of the Bronze Age mud-brick cities we will discuss, Amarna in Egypt, we are able to analyze city design as a deliberate means of changing the social structure of Egyptian society. This revolutionary city takes the lessons of Uruk on religion in the service of the state and develops them to reinforce the rule of the pharaoh, Akhenaten. Here, we also introduce the concept of the house as both an economic unit and a domestic space, an important indicator of the role of the house in the ancient city that we examine in Akrotiri, Athens, and Olynthus.In the four Mediterranean Bronze Age cities of Knossos, Akrotiri, Mycenae, and Tiryns, regular stone architecture makes an appearance. These cities, although they arise from different cultures, share some characteristics in common; we will discuss the idea and mechanisms of the spread of culture across the eastern Mediterranean. The theme of the role of religion continues to be an important one, and the size and placement of religious structures and their consequent meanings are debated with material from Knossos, Akrotiri, and Mycenae and comparisons back to ?atalh?y?k. Mycenae and Tiryns are contrasted with Uruk in their dedication of the high ground in the community, not to the gods, but to the king in the placement of his palace complex. This represents a heretofore unprecedented shift in the focus of urban design.Throughout the Neolithic and Bronze ages, it is possible to point out changes in urban forms, but the notion of “progress” in urban design?that is, reactions to what had come immediately before?is only truly visible with the multiple Greek foundations. We will examine a series of Greek cities?beginning with Athens in the 5th century B.C.; followed by Miletus, Olynthus, and Alexandria; and culminating at Pergamon?to illustrate what can be seen as progress in urban design. Athens in the 5th century has interesting correspondences to Uruk and Amarna. But at Miletus, a dramatic change in Greek urban design, Hippodamian planning, was invented and came to dominate the layout of many Greek and Roman cities with its variation of orthogonal planning. Inevitably, a new model of city design emerged that was anti-Hippodamian; the reasons for that are explored in one of the best examples of it, Pergamon.The examination of a number of Roman cities introduces in detail the issues of the benefits and challenges of urban life, particularly in the city of Rome itself. We also see remarkable variations in urban life in the Roman Empire, from Ostia in Italy to Karanis in Egypt. Rather than the standardized experience one might expect, we see regional variation and cultural identities that differ dramatically even across Roman North Africa.Finally, the last great city foundation of antiquity, Constantinople, encourages us to look backwards and chart its influences from the past and to look forward to its role as the model for the Middle Ages.

    Now he makes the case that living on Mars is not just plausible, but inevitable.It sounds like science fiction, but Stephen Petranek considers it fact: Within twenty years, humans will live on Mars. We'll need to. In this sweeping, provocative book that mixes business, science, and human reporting, Petranek makes the case that living on Mars is an essential back-up plan for humanity and explains in fascinating detail just how it will happen.The race is on. Private companies, driven by iconoclastic entrepreneurs, such as Elon Musk, Jeff Bezos, Paul Allen, and Sir Richard Branson; Dutch reality show and space mission Mars One; NASA; and the Chinese government are among the many groups competing to plant the first stake on Mars and open the door for human habitation. Why go to Mars? Life on Mars has potential life-saving possibilities for everyone on earth. Depleting water supplies, overwhelming climate change, and a host of other disasters — from terrorist attacks to meteor strikes — all loom large. We must become a space-faring species to survive. We have the technology not only to get humans to Mars, but to convert Mars into another habitable planet. It will likely take 300 years to "terraform" Mars, as the jargon goes, but we can turn it into a veritable second Garden of Eden. And we can live there, in specially designed habitations, within the next twenty years.In this exciting chronicle, Petranek introduces the circus of lively characters all engaged in a dramatic effort to be the first to settle the Red Planet. How We'll Live on Mars brings firsthand reporting, interviews with key participants, and extensive research to bear on the question of how we can expect to see life on Mars within the next twenty years.

    While many people attribute procrastination to laziness or a lack of drive, our real motivations to push back and delay important activities and decisions are more complicated than personal weakness. The truth is that humans are well-adapted for basic survival, but they are not so great at managing the stresses and expectations of modern life without a little help.If our own minds so often work against us, how can we get things done without the stress and last-minute panic so common in our hectic 21st-century lives? You’ll learn how in Do It Now: Overcoming Procrastination, taught by Fuschia Sirois, PhD. In 10 lectures, Dr. Sirois will help you better understand the way your mind works and how to overcome the bad habits that are holding you back. Using the latest scientific research on procrastination, Dr. Sirois will give you the insight and guidance you need to set and meet goals, manage your time better, design an environment that will help you succeed, and much more.Best of all, Dr. Sirois makes it clear that procrastination is a natural impulse for most people - sometimes, it can even be beneficial. She encourages you not only to work toward better time management but also to get rid of the burden of guilt and internal pressure that so often accompanies this very common behavior. While the tendency to delay the things we need to do is a deep-rooted habit, you will be able to apply and re-apply the strategies and tools you will acquire in this course for the rest of your life.

    . . . Readers will never again look into the night sky the same way.” —MICHAEL SHERMER, author of The Believing Brain on Parallax: The Race to Measure the CosmosIn 1930, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed; the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement. In its shadow lies an untold, yet equally fascinating, backstory whose cast of characters illuminates the gritty, hard-won nature of scientific progress.The path to a broader mode of cosmic observation was blazed by a cadre of 19th-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as Léon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories—and the ambitious dreamers—behind the birth of modern astronomy.Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory, is the author of Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes.

    Heath in the 1950s and '60s has been described as among the most controversial experiments in US history. His work was alleged at the time to be part of MKUltra, the CIA's notorious "mind control" project. His research subjects included incarcerated convicts and gay men who wished to be "cured" of their sexual preference. Yet his cutting-edge research and legacy were quickly buried deep in Tulane University's archives. Investigative science journalist Lone Frank now tells the complete sage of this passionate, determined doctor and his groundbreaking neuroscience.More than fifty years after Heath's experiments, this very same treatment is becoming mainstream practice in modern psychiatry for everything from schizophrenia, anorexia, and compulsive behavior to depression, Parkinson's, and even substance addiction.Lone Frank uncovered lost documents and accounts of Heath's trailblazing work. She tracked down surviving colleagues and patients, and she delved into the current support for deep brain stimulation by scientists and patients alike. What has changed? Why do we today unquestioningly embrace this technology as a cure? How do we decide what is a disease of the brain to be cured and what should be allowed to remain unprobed and unprodded? And how do we weigh the decades of criticism against the promise of treatment that could be offered to millions of patients?Elegantly written and deeply fascinating, The Pleasure Shock weaves together biography, scientific history, and medical ethics. It is an adventure into our ever-shifting views of the mind and the fateful power we wield when we tinker with the self.

    Every night we surrender it gratefully, only to get it back in the morning. We recognize that we have it, but we can never be sure anyone else does. Consciousness, this unique and perplexing mental state, has been the subject of debate for philosophers and scientists for millennia. And while it is widely agreed within contemporary philosophy that consciousness is a problem whose solutions are likely to determine the fate of any number of other problems, there is no settled position on the ultimate nature of consciousness.What is the most promising way to study this subject? What are the implications that arise from the fact that we have consciousness? What are the ethical and moral issues raised by its presence—or its absence? Questions like these are at the heart of Consciousness and Its Implications, 12 thought-provoking lectures delivered by distinguished philosopher and psychologist Daniel N. Robinson. Rather than merely explain away consciousness, or hide behind such convenient slogans as "it's all in your brain," Professor Robinson reviews some of the special problems that philosophers, psychologists, scientists, and doctors face when taking on such a vexing topic.What Is Consciousness? Much of what we do every day is done without our being directly conscious of the steps taken to complete the task: riding a bicycle, taking a walk, humming a tune. But as natural as this state is, it stands as a very serious threat to any number of core convictions and assumptions in both philosophy and science. One of the overarching goals of this intriguing course is to make clear just what about consciousness serves as such a challenge to these convictions and assumptions.But what makes Consciousness and Its Implications so engaging is more than just the nature of the questions it poses and the issues it tackles. It's the way in which Professor Robinson, the consummate teacher and scholar, conveys this goal in four main points, each of which you explore in depth in these lectures.Consciousness seems to require, for its full understanding, a science not yet available. What distinguishes consciousness from all else is its phenomenology—that is, the act of being conscious is different from all other facts of nature. Conscious awareness is a power that, at times, can be so strong as to greatly affect our senses. The powers of consciousness vary over the course of a lifetime; as such, they can become subject to disease and defect.Throughout the course, Professor Robinson brings this riveting topic vividly to life with real-world examples and striking anecdotes. Review the case of Deep Blue, the IBM computer that in 1997 shocked the world by defeating a human, the chess grand master Garry Kasparov. Does Deep Blue's ability to "outsmart" a human being constitute a kind of consciousness? Or is it a reflection of the human minds that created this complex computer? Consider the case of the sleepwalker, who moves around with purpose and mimics behaviors we see in everyday life, but can remember nothing upon awakening. How does this mental state relate to human consciousness? What would be lost if we lived our entire lives as sleepwalkers?Study the case of a comatose patient who lives in an unbroken sleep state but, after a miraculous recovery, recalls having heard doctors speak about her. How do we interpret this patient's ability to perceive the surrounding world while in a coma? Does the patient's experience reflect some in-between mental state we've yet to define? Look at the case of a child with autism who can perform complicated mental tasks but lacks the most basic human attribute: empathy. How does this inability to imagine other minds affect the child's capacity to enjoy the full experience of human consciousness? Using compelling examples such as these, Professor Robinson weaves a riveting tale of the human condition that will change the way you think about your own mind.Professor Robinson also draws on the wisdom of the world's greatest thinkers—from the ancient Greeks to today's top scientists—to shed light on some of the ethical debates involved in any examination of consciousness. These include John Locke, whose famous "Prince and the Cobbler" hypothesis raised questions about the relationship between one's personal identity and one's body; Ludwig Wittgenstein, whose "Beetle in a Box" scenario holds implications for how we define consciousness both inside and outside ourselves; and Aristotle, who led a pointed discussion on the relationship between the physical world and what he referred to as "real being."You also enter the lab and explore the impact of modern physics and medicine on our understanding of the self. Pondering questions ranging from the most fundamental—"Why are we here?"—to contemporary quandaries about artificial intelligence and the medical decision to prolong life, you'll gain new insights into the complexity of how great minds define consciousness.Consciousness and Its Implications is a chance for you to view this deep and profound subject from all angles. A distinguished scholar in philosophy and neuropsychology, Professor Robinson incorporates many disciplines—psychology, physics, philosophy, medicine—to explore these abiding questions. So embark on a challenging and wholly satisfying exploration of this unique, mysterious, and essential mental faculty. The knowledge you'll gain in this course is not only intriguing—it is crucial to understanding the nature of humanity and the social and ethical obligations that define us all.
