Owing to the work of an astonishing range of visionary thinkers, this fascinating period was the era in which the foundations of the modern Western world were laid. In the medieval era's great minds we find the roots of many aspects of today's world - from the religious/philosophical thought of Augustine, Ambrose of Milan, and Thomas Aquinas to the scientific innovations of Avicenna and Alhacen, the enlightened statesmanship of Charlemagne and Lorenzo de Medici, and the literary creations of Dante and Chaucer.In these 24 lectures, Professor Armstrong leads you on an enthralling journey into the lives of the seminal thinkers of the Middle Ages. In this gallery of extraordinary minds, you'll encounter the leading lights of a world-shaping era, including figures such as Maimonides, Hildegard of Bingen, Bernard of Clairvaux, Peter Abelard, and Francesco Petrarch. Professor Armstrong goes to great lengths to bring these historic figures to life, revealing both the great intellectual contributions and the personal strivings, challenges, and triumphs of some of history's most remarkable human beings. These compelling lectures take you deeply into the heart of one of civilization's most dynamic and impactful eras.Listening Length: 11 hours and 59 minutes

    Along the way Stephen Baxter looks at our place in the universe, considers the possibility that we are in fact alone, and wonders whether that fact gives us the right to inherit everything. He also looks at how we might strive to overcome the limitations of the physical universe and win the deepest future. Stephen Baxter has brought his trademark narrative flair and imaginative brilliance to the latest ideas in physics and cosmology and produced a breathtaking guide to our possible futures.

    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.

    On that day, astronomer Arthur Eddington and his team observed a solar eclipse and found something extraordinary: gravity bends light, just as Einstein predicted. The finding confirmed the theory of general relativity, fundamentally changing our understanding of space and time.A century later, another group of astronomers is performing a similar experiment on a much larger scale. The Event Horizon Telescope, a globe-spanning array of radio dishes, is examining space surrounding Sagittarius A*, the supermassive black hole at the center of the Milky Way. As Ron Cowen recounts, the foremost goal of the experiment is to determine whether Einstein was right on the details. Gravity lies at the heart of what we don't know about quantum mechanics, but tantalizing possibilities for deeper insight are offered by black holes. By observing starlight wrapping around Sagittarius A*, the telescope will not only provide the first direct view of an event horizon--a black hole's point of no return--but will also enable scientists to test Einstein's theory under the most extreme conditions.Gravity's Century shows how we got from the pivotal observations of the 1919 eclipse to the Event Horizon Telescope, and what is at stake today. Breaking down the physics in clear and approachable language, Cowen makes vivid how the quest to understand gravity is really the quest to comprehend the universe.

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

    Now you can learn the basics of jazz and its history in a course as free-flowing and original as jazz itself. Taught by Professor Bill Messenger of the Peabody Institute, the lectures in this course are a must for music lovers. They will have you reaching deep into your own music collection and going straight out to a music store to add to it. Professor Messenger has spent his life in music as student, teacher, and professional musician. He has studied and lectured at the famed Peabody Institute and written an acclaimed book on music activities aimed at older adults. And as a pianist, he has: Played in ragtime ensembles, swing bands, Dixieland bands, and modern jazz groups Been a successful studio musician in the early days of rock 'n' roll Accompanied performers as renowned as Lou Rawls and Mama Cass Elliot Opened for Bill Haley and the Comets. So it is no wonder that the course he has created is so thorough and enjoyable. Lectures, Piano, and Guest Performers It's a rich mix of jazz, its elements, era, and practitioners. Professor Messenger frequently turns to his piano to illustrate his musical points, often with the help of guest performance artists and lots of original music. The lectures follow the story of jazz in its many shapes, including: Ragtime The blues The swing music of the big band era Boogie-woogie Big band blues The rise of modern jazz forms: bebop, cool, modal, free, and fusion. Cakewalks, Vaudeville, and Swing Beginning with the music and dance of the antebellum plantation, Professor Messenger reveals how the "cakewalks" of slave culture gave birth to a dance craze at the 19th century's end that was ignorant of its own humble roots. He considers how minstrel shows, deriving from Southern beliefs that held black culture to be decidedly inferior, eventually created a musical industry that African American musicians would dominate for decades to come. You will learn how and why jazz, a difficult genre to define, was central to the music they created. Roots in Ragtime Professor Messenger explains how jazz was born-or conceived-in the ragtime piano tunes of turn-of-the-century America. Together with the Dixieland funeral music of New Orleans, this new, "syncopated" music popularized a sound that took America's vaudeville establishments by storm. Professor Messenger notes that ragtime's most popular composer, Scott Joplin, at first resisted the new craze. But after becoming intrigued by that "ragged" sound at the Chicago World's Fair of 1893, he became the writer of the most memorable rags ever, including "Maple Leaf Rag" and "The Entertainer." Drawing on the blues, an emotional but harmonically simple music, jazz was ensconced as a popular genre in the American psyche by the 1920s. The Surprising Origin of the "St. Louis Blues" One interesting story about the blues covered in the course concerns W. C. Handy, a man often referred to as the "father of the blues." As Professor Messenger reveals that, in truth, Handy didn't like the blues very much and wasn't convinced the public would buy it. It was only after he saw a band of blues players literally showered with money after a performance that he began writing the music in earnest. Handy was at the same World's Fair Joplin attended, and he heard a song he later arranged into what became the famous "St. Louis Blues." Professor Messenger points out, nothing about the song was original; it was a melting pot of many influences. The blues is, in his words, the "emotional germ of jazz." It is the place jazz always returns to when it veers too far into the abstract or academic. An Innovation that Changed Jazz Forever One of the most important events in the history of jazz, and all performance, was the invention of the microphone in 1924. Before the microphone, singers needed big voices to project their voices across large music halls, and the booming styles of performers such as Bessie Smith and Al Jolson met those requirements admirably. After the microphone, though, things were very different. The new invention did more than simply allow for the use of quieter instruments like the guitar and string bass. It also brought smaller-voiced singers-Bing Crosby, Mel Torme, Frank Sinatra, for instance-into the limelight. Into the 1930s and 40s, popular music became heavily arranged for bigger and bigger bands. By the time the swing era of America's big bands took hold around World War II, jazz had reached new popular heights. You will learn why swing became so popular-the syncopation and improvisation of early jazz, in the context of careful arrangements, combined planning and spontaneity in a unique way. Though not to be confused with the sound of competing society bands, swing music gave talents like Benny Goodman a chance to improvise within the framework of Top 40 hits.More than Swing The development of jazz into swing electrified popular music. You learn: How boogie-woogie, a precursor of rock 'n' roll that was primed with a heavy-handed, highly rhythmic style, found widespread success in the 1940s until its ubiquity forced it out of fashion How big band blues, where the simplicity of the blues standard was overlaid on the pop song, fused the worlds of folk art and high art How bebop-an austere, anxious music whose success was blazed by the genius of Dizzy Gillespie and Charlie Parker-worked against the commercial spread of swing How modern jazz spans everything-from the cool jazz of the 1950s to the fusion jazz of the 1990s, with several stops in between. Music for Today In recent decades many forms of modern jazz-including cool, modal, free, and fusion-have had their devoted following. All serve to prove that jazz is a generic music that comprises many varieties. True to its name, jazz has defied definition, category, and stagnation. And this course-in toe-tapping, finger-snapping ways-will feed your intellectual curiosity and appreciation.

    But what is time, exactly? Do children experience it the same way adults do? Why does it seem to slow down when we’re bored and speed by as we get older? How and why does time fly?In this witty and meditative exploration, award-winning author and New Yorker staff writer Alan Burdick takes readers on a personal quest to understand how time gets in us and why we perceive it the way we do. In the company of scientists, he visits the most accurate clock in the world (which exists only on paper); discovers that “now” actually happened a split-second ago; finds a twenty-fifth hour in the day; lives in the Arctic to lose all sense of time; and, for one fleeting moment in a neuroscientist’s lab, even makes time go backward. Why Time Flies is an instant classic, a vivid and intimate examination of the clocks that tick inside us all.

    Among those you'll investigate are the accounts of the creation of the world in Hesiod's Theogony and Ovid's Metamorphoses; the gods Zeus, Apollo, Demeter, Persephone, Hermes, Dionysos, and Aphrodite; the Greek heroes, Theseus and Heracles (Hercules in the Roman version); and the most famous of all classical myths, the Trojan War.Professor Vandiver anchors her presentation in some basics. What is a myth? Which societies use myths? What are some of the problems inherent in studying classical mythology? She also discusses the most influential 19th- and 20th-century thinking about myth's nature and function, including the psychological theories of Freud and Jung and the metaphysical approach of Joseph Campbell. You'll also consider the relationship between mythology and culture (such as the implications of the myth of Demeter, Persephone, and Hades for the Greek view of life, death, and marriage), the origins of classical mythology (including the similarities between the Theogony and Mesopotamian creation myths), and the dangers of probing for distant origins (for example, there's little evidence that a prehistoric "mother goddess" lies at the heart of mythology).Taking you from the surprising "truths" about the Minotaur to Ovid's impact on the works of William Shakespeare, these lectures make classical mythology fresh, absorbing, and often surprising.Disclaimer: Please note that this recording may include references to supplemental texts or print references that are not essential to the program and not supplied with your purchase.©2000 The Teaching Company, LLC (P)2000 The Great Courses

    

    His controversial contention is that the Universe itself can be regarded as a living entity which, rather than being unique, has evolved through Darwinian selection among a multitude of rival universes, competing for existence in spacetime. This vision of the Universe as a product of evolution by natural selection echoes and extends the idea that all the living things on Earth may form an interlocking web which can be regarded as a single living organism, Gaia. On scales intermediate between that of a single planet and that of the entire Universe, whole galaxies of stars, like our Milky Way system, also show properties usually associated with living systems, and evidence of evolution. Along the way we learn why the laws of physics should be as they are, and whether human beings have a special place in the living Universe.
