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.

    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.

    The lectures lead a startling voyage into the human mind, explaining not only how the various aspects of your memory operate, but the impact memory has on your daily experience of life.The various memory systems provide the continuity of consciousness that allows the concept of "you" to make sense, creating the ongoing narrative that makes your life truly yours. Without those systems and the overall experience of memory they make possible, you would have no context for the most crucial decisions of your life. You would have to make—without the benefit of experience and knowledge—the decisions that determine not only your quality of life, but your very survival. And your ability to learn, or even to form the personality that makes you unique, would similarly be set adrift.Course Lecture Titles24 Lectures, 30 minutes per lecture 1.Memory Is a PartyUsing the metaphor of a party whose “guests” include the different components of the complex interactions that make up memory, Professor Joordens introduces you to several kinds of memory—including episodic, semantic, and procedural—to arrive at an initial understanding of the variety of processes at work in human “memory.”2. The Ancient “Art of Memory”Techniques to embed and retrieve memories more easily—so-called mnemonic strategies—date back at least to classical Greece. See how one such technique—the Method of Loci—can help improve the episodic memory you depend on to recall a group of items such as grocery or to-do lists.3. Rote Memorization and a Science of ForgettingIs a mnemonic strategy always the most useful? Examine rote memorization and how it differs from mnemonics. Also, get an introduction to the work of Hermann Ebbinghaus, whose 19th-century experiments in remembering and forgetting marked the first scientific examination of memory.4. Sensory Memory—Brief Traces of the PastBegin a deeper discussion of the different kinds of memory, beginning with sensory memory and how its brief retentive power lets you switch from one stimulus to another—and even gives you your sense of “the present moment.” Here, the focus is on iconic (or visual) memory and its auditory counterpart, echoic memory.5. The Conveyor Belt of Working MemoryPlunge into the mental processes that allow you to work with information, often with the goal of solving a problem. You learn that these processes can also be used to keep information briefly “in mind,” though they require effort and are prone to interference.6. Encoding—Our Gateway into Long-Term MemoryHow does information make its way from your temporary working memory into long-term memory so you can access it again when you need it? This introduction to encoding explains the process and offers useful tips for improving your own recall.7. Episodic and Semantic Long-Term MemoryStrengthen your grasp of how these two key memory systems function. You explore the relationship between them with analogies that range from the job requirements of London taxi drivers to the famed “holo-deck” of the Star Trek television series.8. The Secret Passage—Implicit MemoryEncounter still another category of memory—a way in which your experiences can enter long-term memory without the kind of “effortful encoding” discussed earlier. You learn why this sort of memory creation is vitally important, yet also unreliable as a substitute for conscious effort.9. From Procedural Memory to HabitIn this lecture, you see that your memory for procedures is useful not only in the “muscle memory” of physical skills, but also in cognitive processes. Also, learn about constructivist learning, in which the explicit structure of a procedure—which is usually taught verbally—instead is learned implicitly during exploratory practice.10. When Memory Systems Battle—Habits vs. GoalsWhat happens when implicit or procedural memories become so powerful they seize control? In this examination of the tenacity of habits, learn how and why habits are formed and what steps might be useful in changing them, or at least regaining control.11. Sleep and the Consolidation of MemoriesDoes sleep play a role in strengthening memories of your experiences during the day? Gain a sense of the latest research about a subject that is difficult to study as you explore the relationship between sleep and memory, including the possible link between specific sleep stages and specific kinds of memory.12. Infant and Early Childhood MemoryHow does the maturation of memory fit into a child’s overall brain development? Gain invaluable and surprising insights into the month-by-month and year-by-year development of a child’s capacity for memory, beginning in the womb and continuing on with its dramatic development after entry into the world.13. Animal Cognition and MemoryDoes an elephant really never forget? Expand your study of memory to investigate the extent to which the mysterious abilities of humans may also exist in animals and, if so, how they might differ from our own.14. Mapping Memory in the BrainAlmost two decades since its revolutionary appearance, fMRI—functional magnetic resonance imaging—is allowing researchers to watch the living human brain at work, with no harm or discomfort to the subject. Explore what happens in several areas of the brain as memories are created or retrieved.15. Neural Network ModelsCan computer models mimic the operations of the human brain? Examine the use of neural network modeling, in which biologically inspired models posited by researchers in cognitive neuroscience are advancing our understanding of just how those operations take place.16. Learning from Brain Damage and AmnesiasLeave the world of computers for that of neuropsychology as you focus on the life situations of several patients who have suffered some form of brain injury. You learn how damage to different areas of the brain can have dramatically different impacts on memory and how these patients experience the world.17. The Many Challenges of Alzheimer’s DiseaseIn a lecture that explores one of our most frightening diseases from both the caregiver’s and sufferer’s perspectives, learn how Alzheimer’s progresses, how that progression may be forestalled, and ways in which technology may be able to help through the emerging field of “cognitive prosthetics.”18. That Powerful Glow of Warm FamiliarityWhy does something familiar to us actually feel that way? Discover the sources of familiarity as you are introduced to the concepts of perceptual fluency and prototypes, and explore some surprising ways that those feelings of familiarity can trump other considerations.19. Déjà Vu and the Illusion of MemoryIs déjà vu simply an illusion of memory? If so, can we learn more about memory by trying to understand how this common phenomenon comes about? Examine some of the theories that have 20. Recovered Memories or False Memories?Is episodic memory subject to the same pitfalls as misattributed feelings of familiarity? Can we “remember” things that never took place with the same intensity and certainty as those that did? Gain new insights into what is at stake when long-forgotten “memories” resurface.21. Mind the Gaps! Memory as ReconstructionMetaphors for memory usually reference information storehouses of some kind, such as library stacks or computer hard drives, from which episodic memories are “retrieved.” Learn about the extent to which we actually construct our memories anew each time we summon them and how this explains common memory errors.22. How We Choose What's Important to RememberDoes our brain always make decisions for us about which aspects of our experience to encode for later recall, or can we influence that process ourselves? Learn potentially powerful techniques for influencing the shape of future memories.23. Aging, Memory, and Cognitive TransitionApply a reality check to the popularly held belief that memory naturally declines as we age. Learn what happened when a researcher corrected for the age-related variables long-ignored by traditional testers—and what conclusions we can draw about what lies ahead for us as we grow older.24. The Monster at the End of the BookContemplate the significance of what you’ve learned, with special attention to the common question of whether you can improve your episodic memory—remembering what you want to recall, forgetting what you’d rather not, and making choices about how to achieve a balance.

    In what began as groundbreaking three-part series in the New Yorker, for which she won a National Magazine Award in 2006, Kolbert cuts through the competing rhetoric and political agendas to elucidate for Americans what is really going on with the global environment and asks what, if anything, can be done to save our planet. Now updated and with a new afterword, Field Notes from a Catastrophe is the book to read on the defining issue and greatest challenge of our times.

    It examines the canonical Gospels of Mark, Matthew, Luke, and John familiar to us from the New Testament, as well as the many other, apocryphal narratives and literary works that have contributed to our perceptions of Jesus, Mary, and Christianity. All of these works are encompassed by the word "Gospel."

    (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world. Welcome to the science wars—a long-running battle over the status of scientific knowledge that began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has re-emerged in today's conflict between science and religion over issues such as evolution.Professor Steven L. Goldman, whose Teaching Company course on Science in the 20th Century was praised by customers as "a scholarly achievement of the highest order" and "excellent in every way," leads you on a quest for the nature of scientific reasoning in this intellectually pathbreaking lecture series, Science Wars: What Scientists Know and How They Know It.Those who have taken Professor Goldman's previous course, which is an intensive survey of the revolution in scientific knowledge from 1900 to 2000, may have wondered: if what counts as scientific knowledge can transform so dramatically within only 100 years, what exactly is scientific knowledge? Science Wars addresses this surprisingly difficult question.Five Centuries of the Science WarsIn 24 half-hour lectures, Science Wars explores the history of competing conceptions of scientific knowledge and their implications for science and society from the onset of the Scientific Revolution in the 1600s to the present. It may seem that the accelerating pace of discoveries, inventions, and unexpected insights into nature during this period guarantees the secure foundations of scientific inquiry, but that is far from true. Consider these cases:The scientific method: In the 1600s the English philosopher Francis Bacon defined the scientific method in its classic form: the use of inductive reasoning to draw conclusions from an exhaustive body of facts. But "no scientist has ever been a strict Baconian," says Professor Goldman. "If you followed that, you would get nowhere."A "heated" debate: Around 1800 the dispute over the nature of heat was resolved in favor of the theory that heat is motion and not a substance given off during burning. But then the French mathematical physicist Joseph Fourier wrote a set of equations that accurately described how heat behaves regardless of what it "really" is, which, Fourier contended, was not a scientific question at all.Paradigm shifts: The publication in 1962 of Thomas Kuhn's The Structure of Scientific Revolutions precipitated a radical change in attitudes toward scientific knowledge, prompted by Kuhn's insight that science is not an entirely rational enterprise, and that its well-established theories (or paradigms) are overturned in a revolutionary, nonlogical process.Postmodern putdown: The postmodern attack on science as a privileged mode of inquiry made some headway in the late 20th century. But the credibility of the movement wilted in 1996, when a postmodern journal unwittingly published a spoof by physicist Alan Sokal, purporting to prove that physical theory was socially constructed. Sokal then exposed his piece as a parody.In the penultimate lecture of the course, Professor Goldman considers intelligent design—the argument that evolution can't account for the immense complexity of life and that a master designer must be at work. He approaches this topical debate by asking: What are the minimum criteria that define a hypothesis as scientific, and does intelligent design qualify? Having already covered five centuries of the science wars in the previous lectures, you will analyze this controversy with a set of tools that allows you to see the issues in a sharp, new light.What Is Reality?"Fasten your seatbelts," says Professor Goldman at the outset of Lecture 21—an advisory that applies equally to the whole course, which covers an astonishing array of ideas and thinkers. Throughout, Professor Goldman never loses his narrative thread, which begins 2,400 years ago with Plato's allegorical battle between "the gods" and "the earth giants"—between those for whom knowledge is universal, necessary, and certain; and those for whom it cannot be so and is based wholly on experience.The problem of what constitutes scientific knowledge can be illustrated with one of the most famous and widely accepted scientific theories of all time, Nicolaus Copernicus's heliostatic (stationary sun) theory of the solar system, which has undergone continual change since it was first proposed in 1543: Copernicus called for the planets to move in uniform circular motion around the sun, slightly displaced from the center. Using observations by Tycho Brahe, Johannes Kepler revised the Copernican model, discarding the ancient dogma of circular motion, which did not fit the data. Instead, he guessed that the planets in fact move in elliptical orbits. In his influential work endorsing the Copernican theory, Galileo ignored Kepler's corrections and opted for circular motion. Notoriously, the Catholic Church condemned Galileo for heresy. But the church was actually correct that he had no basis for claiming the heliocentric theory was true, rather than simply an interpretation of experience. Galileo's picture of space was superseded by Newton's and later by Einstein's, which also will doubtless be revised. Even something as basic as the elliptical motion of the planets is a vast oversimplification. There are no closed curves in space, since the solar system is moving around the center of the galaxy; the galaxy is moving within the local cluster; and the local cluster is also moving. Although we still call the conventional picture of the solar system Copernican astronomy, there is effectively no resemblance between astronomy today and Copernicus's 1543 theory of the heavens. The same is also true of other theories, such as the atomic theory of matter. All scientific theories are in a state of ceaseless revision, which raises the question of what reality "really" is. As the contemporary philosopher of science Mary Hesse has pointed out, the lesson of the history of science seems to be that the theories we currently hold to be true are as likely to be overturned as the theories they replaced!Sharpen Your Understanding of What Science IsThe uncertainty about the status of scientific knowledge and about the objectivity of the scientific enterprise led to a broad assault on science in the late 20th century by sociologists, philosophers, and historians, many connected with the postmodern movement. The lectures covering this attack and the ensuing counterattack by scientists are some of the most thrilling in the course and involve a number of figures whom Professor Goldman knows personally.Of one of the firebrands in this conflict, the late Viennese philosopher of science Paul Feyerabend, Professor Goldman says, "I myself took a seminar with Feyerabend when he was teaching at Berkeley in the early 1960s. … Feyerabend was not really off the wall, although he was often depicted that way. … He too recognized, as everyone must, that after all, science does work and science is knowledge of a sort. It's just not the absolute knowledge that scientists and philosophers have historically claimed that it is."By the time you reach the end of this course, you will understand exactly what science is, and you will be enlightened about a fascinating problem that perhaps you didn't even know existed. "There have been a raft of popular books about what scientists know," says Professor Goldman, "but to the best of my knowledge, there is not a single one of these popular books that focuses centrally on the question of how scientists know what they know."This course serves as that book.Course Lecture Titles1.

    But what made the city the perfect environment for so many great developments? How did London endure the sweeping historical revolutions and disasters without crumbling? Find the answers to these questions and more in these 24 fascinating lectures.Professor Bucholz takes you through the history of this magnificent metropolis, from its birth as an ancient Roman outpost to its current status as a global village. You'll study the many epic chapters in British and world history - including the English Renaissance, the turmoil of the English civil war, and the epic conflicts of World Wars I and II - through the lens of this amazing capital.What makes the course unique is that it takes you deep into the streets of London during formative periods in its history. Professor Bucholz continuously emphasizes the importance of understanding and experiencing the sights and sounds of London as it was lived by its residents. You'll come to know what daily life was like in historical London, learning the secret histories behind places such as Westminster Abbey, Piccadilly Circus, and London Bridge.This unforgettable look at an unforgettable city will undoubtedly delight and surprise you. By the final lecture, you'll come to realize just what Samuel Johnson meant when he famously declared, "there is in London, all that life can afford."

    These 24 thought-provoking lectures offer you the chance to reflect on some of the most powerful moral issues we face in our daily lives: Is it ever OK to lie? What are our moral obligations to others? What is the key to living the good life? From Plato to Kant to Bonhoeffer, you'll see how some of the world's greatest thinkers from across the ages have approached similar problems. Professor Martin provides a complete picture of various ethical schools and approaches and applies this rich philosophical overview to "case studies" relevant to our contemporary lives. You'll explore all the ins and outs of issues such as business ethics, love and marriage, privacy and technology, genetic engineering, animal rights, and much more. Engaging stories and thought experiments bring these issues to life, showing what different philosophical theories have to say about real-world ethical dilemmas. According to Professor Martin, the trick is to understand that the mind is like a parachute; it only works when it's open. Rather than take a side in any particular debate, this course provides a framework for thinking through a host of debates and dilemmas from all sides. Through it all, Professor Martin is a sympathetic guide, helping you think through some of our most complex decisions.

    Though he never wrote down his thoughts, he had a brilliant pupil in Plato, who immortalized his teacher's legacy in 35 timeless dialogues that laid the philosophical basis for Western civilization.Professor Michael Sugrue of Princeton University brings the Socratic quest for truth alive in these lectures, which discuss ideas that are as vital today as they were 25 centuries ago. Ideas about truth, justice, love, beauty, courage, and wisdom. Ideas that can change lives and reveal the world in new ways to the true student.Professor Sugrue reveals the inner structure, action, and meaning of 17 of Plato's greatest dialogues, making this course an indispensable companion for anyone interested in philosophy in general or Platonic thought in particular.

    It’s not just that the grid has grown old and is now in dire need of basic repair. Today, as we invest great hope in new energy sources--solar, wind, and other alternatives--the grid is what stands most firmly in the way of a brighter energy future. If we hope to realize this future, we need to re-imagine the grid according to twenty-first-century values. It’s a project which forces visionaries to work with bureaucrats, legislators with storm-flattened communities, moneymen with hippies, and the left with the right. And though it might not yet be obvious, this revolution is already well under way.Cultural anthropologist Gretchen Bakke unveils the many facets of America's energy infrastructure, its most dynamic moments and its most stable ones, and its essential role in personal and national life. The grid, she argues, is an essentially American artifact, one which developed with us: a product of bold expansion, the occasional foolhardy vision, some genius technologies, and constant improvisation. Most of all, her focus is on how Americans are changing the grid right now, sometimes with gumption and big dreams and sometimes with legislation or the brandishing of guns.The Grid tells--entertainingly, perceptively--the story of what has been called “the largest machine in the world”: its fascinating history, its problematic present, and its potential role in a brighter, cleaner future.
