Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology. Among Tesla's creations were the channeling of alternating current, fluorescent and neon lighting, wireless telegraphy, and the giant turbines that harnessed the power of Niagara Falls.

    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.

    Archaeology brings us face-to-face with our distant ancestors, with treasures of the past, and with life as it was lived in long-ago civilizations.Despite the fascinating and often romantic appeal of archaeology, many of us have little idea of what the field actually involves.

    It's ever-present. Without it, you would die in minutes. And it has an epic story to tell.In Caesar's Last Breath, New York Times bestselling author Sam Kean takes us on a journey through the periodic table, around the globe, and across time to tell the story of the air we breathe, which, it turns out, is also the story of earth and our existence on it.With every breath, you literally inhale the history of the world. On the ides of March, 44 BC, Julius Caesar died of stab wounds on the Senate floor, but the story of his last breath is still unfolding; in fact, you're probably inhaling some of it now. Of the sextillions of molecules entering or leaving your lungs at this moment, some might well bear traces of Cleopatra's perfumes, German mustard gas, particles exhaled by dinosaurs or emitted by atomic bombs, even remnants of stardust from the universe's creation.Tracing the origins and ingredients of our atmosphere, Kean reveals how the alchemy of air reshaped our continents, steered human progress, powered revolutions, and continues to influence everything we do. Along the way, we'll swim with radioactive pigs, witness the most important chemical reactions humans have discovered, and join the crowd at the Moulin Rouge for some of the crudest performance art of all time. Lively, witty, and filled with the astounding science of ordinary life, Caesar's Last Breath illuminates the science stories swirling around us every second.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

    But amid the "dark" Middle Ages, the Abbasid Empire, which ruled the Middle East as well as much of Northern Africa and Central Asia from 750 to 1258, serves as a vitally important but often overlooked bridge between the ancient and modern worlds.The History and Achievements of the Islamic Golden Age is your opportunity to get to know the story and the accomplishments of this great period in human civilization. Taught by acclaimed lecturer Eamonn Gearon, these 24 remarkable lectures offer brilliant insights into an era too often overlooked by traditional history textbooks.

No tool in the entire universe of scientific exploration can come close to matching the ability of your brain to use information sensed by your eyes, ears, skin, tongue, and nose to produce a rich sensory experience in just milliseconds.In recent years, neurobiologists and other scientists have uncovered new insights into how your senses work and the amazingly complex and fascinating things they can do. And now you can share in what they've discovered-through this intriguing series of 24 lectures from an award-winning teacher.Knowing how your senses work and the ways they shape how you see, interact with, and understand your life will help you think more critically about everything you sense and perceive, strengthen your appreciation of the senses that make this possible, prepare you to be an active consumer of new scientific evidence on how our senses work, and much more.With Professor Vishton as your guide, you'll. consider each of your senses from multiple perspectives:Explore how your brain processes different sensory informationConsider how your senses work together and within the context of the environment around youdiscover how your senses connect you to the world and other people.Using both cutting-edge research and simple experiments, tests, and demonstrations to hone your understanding, he has created a world-class learning experience that will change the way you think about your senses.

    But there is a method for avoiding such pitfalls of human nature, and it's called skepticism. By using rational inquiry and seeing subjects from a scientific perspective, we can approach even the most sensitive claims with clear eyes to ultimately arrive at the truth. During 18 lectures that will surprise, challenge, and entertain you, you will learn how to think, not just what to think-and you'll come to understand why extraordinary claims require extraordinary evidence.You'll discover how skepticism can help differentiate between real science and pseudoscience, as well as between "scientific" history and pseudohistory-distinctions that have serious educational and political implications.Fascinating case studies illustrate how you can apply the methods of skepticism to detect specious claims and faulty logic in any scenario you encounter such as:•The methodology employed by Holocaust deniers•Arguments made by proponents of creationism•The biology of near-death experiences and the sensed-presence effect•Psychic abilities and other "paranormal" phenomena.As you learn how our brains work to form beliefs, you'll examine the classic fallacies of thought that lead us to experience mistakes in thinking and to form bad arguments in favor of our beliefs.Is there a God? Is there life after death? Is there a basis for morality without God? Skepticism 101 doesn't shy away from controversial questions, nor does it give final answers. What it offers are methods and hard evidence for rationally evaluating various claims and positions, and an opportunity to understand why you believe what you believe.Listening Length: 9 hours and 10 minutes

    

    As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man." In fact, civilization itself began in the quest for food. Humanity's transition to agriculture was not only the greatest social revolution in history, but it directly produced the structures and institutions we call "civilization." In 36 fascinating lectures, award-winning Professor Albala puts this extraordinary subject on the table, taking you on an enthralling journey into the human relationship to food. With this innovative course, you'll travel the world discovering fascinating food lore and culture of all regions and eras - as an eye-opening lesson in history as well as a unique window on what we eat today.

    After much consideration, we determined that it actually would be more beneficial to create a course that compares and contrasts the two major global economic theories, examining them in ways that move past the polemics many of us are used to and looking at these systems as they relate to one another and the world at large.Politics and economics are inextricable, so it can be difficult to find the right person to tackle such a complex and often polarizing subject as objectively as possible. Luckily, we found Professor Edward Stuart, an economist and teacher who specializes in comparative economics. Professor Stuart brings not only economic expertise, but personal experience gleaned from teaching, traveling, and consulting all over the world, and it is this wide lens of experience that helps make Capitalism vs. Socialism such an engaging new entry in our library of courses.

    Taking as territory everything from the Big Bang to the rise of civilization, Bryson seeks to understand how we got from there being nothing at all to there being us. To that end, he has attached himself to a host of the world’s most advanced (and often obsessed) archaeologists, anthropologists, and mathematicians, travelling to their offices, laboratories, and field camps. He has read (or tried to read) their books, pestered them with questions, apprenticed himself to their powerful minds. A Short History of Nearly Everything is the record of this quest, and it is a sometimes profound, sometimes funny, and always supremely clear and entertaining adventure in the realms of human knowledge, as only Bill Bryson can render it. Science has never been more involving or entertaining.

    Modern science demonstrates that this mental hardwiring, traceable to the survival needs of our earliest ancestors, is at the root of many of the psychological and behavioral problems that we face today.For thousands of years, people have used mindfulness practices—techniques to develop awareness of present experience with acceptance—to deal effectively with a wide range of life challenges. And, a large and fascinating body of scientific research now validates the remarkable benefits of mindfulness practice for psychological as well as physical health.But how exactly does mindfulness work, in scientific terms? How can understanding the science and practice of mindfulness improve everyday life? And how can the human brain, whose very functioning gives rise to so many of the problems we struggle with, actually provide a solution?Now, in the 24 fascinating lectures of The Science of Mindfulness, Professor Ronald D. Siegel, a clinical psychologist on the faculty of Harvard Medical School, reveals the science behind mindfulness in compelling detail and demonstrates its application to an extraordinary range of human problems—psychological, social, and medical. You’ll closely examine the neurobiology involved, leaving you with a clear knowledge of the science underlying ancient practices that are now profoundly influencing the contemporary world. And you’ll learn many practical ways you can use mindfulness techniques in your own life.
