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

    His father, Hamilcar, was also a great strategist and master tactician who imposed Carthaginian rule over much of present-day Spain. After Hamilcar led the Carthaginian forces against Rome in the First Punic War, Hannibal followed in his father’s footsteps, leading Carthage in the Second Punic War.From the time he was a teenager, Hannibal fought against Rome. He is famed for leading Carthage’s army across north Africa, into Spain, along the Mediterranean coast, and then crossing the Alps with his army and war elephants. Hannibal won victories in northern Italy by outmaneuvering his Roman adversaries and defeated a larger Roman army at the battle of Cannae in 216 BC. Unable to force Rome to capitulate, he was eventually forced to leave Italy and return to Carthage when a savvy Roman general named Scipio invaded north Africa. Hannibal and Scipio fought an epic battle at Zama, which Hannibal lost. The terms of surrender were harsh and many Carthaginians blamed Hannibal, eventually forcing him into exile until his death.To this day Hannibal is still regarded as a military genius. Napoleon, George Patton, and Norman Schwarzkopf, Jr. are only some of the generals who studied and admired him. His strategy and tactics are still taught in military academies. He is one of the figures of the ancient world whose life and exploits never fail to impress. Historian Patrick N. Hunt has led archeological expeditions in the Alps and elsewhere to study Hannibal’s exploits. Now he brings Hannibal’s incredible story to life in this riveting and dramatic book.

    In the Roman Empire no one is safe from the sting of betrayal: man, woman or child.As a boy, Nero's royal heritage becomes a threat to his very life, first when the mad emperor Caligula tries to drown him, then when his great aunt attempts to secure her own son's inheritance. Faced with shocking acts of treachery, young Nero is dealt a harsh lesson: it is better to be cruel than dead.While Nero idealizes the artistic and athletic principles of Greece, his very survival rests on his ability to navigate the sea of vipers that is Rome. The most lethal of all is his own mother, a cold-blooded woman whose singular goal is to control the empire. With cunning and poison, the obstacles fall one by one. But as Agrippina's machinations earn her son a title he is both tempted and terrified to assume, Nero's determination to escape her thrall will shape him into the man he was fated to become, an Emperor who became legendary.With impeccable research and captivating prose, The Confessions of Young Nero is the story of a boy's ruthless ascension to the throne. Detailing his journey from innocent youth to infamous ruler, it is an epic tale of the lengths to which man will go in the ultimate quest for power and survival.

    A series of 24 Lectures on the New England Transcendalist Movement delivered by Ashton Nichols, Professor of English at Dickinson College.

    But have you ever wondered how a religion that doesn't even have a god could have accomplished this?Now you have the opportunity to have your questions answered, as this series of 24 lectures by an award-winning teacher traces the history, principles, and evolution of a theology that is both familiar and foreign.You'll learn the astonishing story of Siddhartha Gautama - who was to become the Buddha, or "enlightened one" - the Indian prince who abandoned wife, son, and a privileged life to seek the meaning of life and death, and whose "awakening" and subsequent teachings have since impacted the world as few others have.And you'll learn what happened after his death, as his followers began to share his teachings about the "Four Noble Truths" and the "Path" to Enlightenment. You'll see how Buddhist beliefs underwent significant and even radical change, with different varieties of Buddhism having to take shape as those beliefs spread across India, Central Asia, China, Japan, and virtually every corner of the Western world, such as becoming more respectful of one's duties to family and ancestors in China or becoming reconciled with local deities in Japan.

    Robinson Crusoe. Harry Potter. What do these memorable characters have in common? Why do we turn to certain stories again and again? And what impact have they made on world history? These 24 eye-opening lectures give fresh insight into some of the greatest heroes in world literature, from warriors such as Beowulf and Odysseus to unexpected heroes such as Uncle Tom and Sancho Panza.Professor Shippey gives you an inside glimpse into the writer's process. Learn how authors "write into the gap" to flesh out-or, in some cases, reimagine altogether-old stories, making them new for new readerships with different values. By examining what makes these heroes such compelling characters, you'll see how they provide a window to better understand ourselves.From the beginnings of world literature through today's bestsellers, look at what makes characters successful-and how they reflect our changing cultural mores. For instance, after the horrors of global war in the 20th century, the world was waiting for a hero like Frodo Baggins, J.R.R. Tolkien's meek hobbit hero, someone called to duty rather than born strong and fearless.You'll also examine ways that great heroes have changed the course of history, defining nations and redefining our sense of self and our relationships. From the mythical journey of Aeneas to Jane Austen's country dances, you'll survey a wealth of memorable stories and consider why such heroes were necessary-and how they continue to influence our lives today.

    

    It repays us many times over to be good economists. Economic issues are active in our lives every day. However, when the subject of economics comes up in conversation or on the news, we can find ourselves longing for a more sophisticated understanding of the fundamentals of economics.36 lectures | 30 minutes each.

    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.

    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.

    These portraits of the emperors form the building blocks of an invaluable and highly readable popular history of Imperial Rome, brought to life using the colorful testimony of contemporary authors.

    Lowly born, he rose to prominence as he spread his vision of the redemption of the world. He attracted the attention of faithful disciples and suspicious local authorities. Eventually, he was tried, convicted, and executed.Today, his story is known the world over. And yet, more than two millennia later, great thinkers and everyday people still struggle to answer a single question: Who is Jesus? * Was he a wise sage who culled powerful teachings from centuries of Jewish tradition to create a new world vision of peace and love? * Or was he indeed God himself, the embodiment of divinity on earth, sent to bring salvation and redemption from sin? * Did his promise of salvation apply to all humankind or was it limited to only a few followers? And how could one participate in that promise?Since the earliest days of the faith, questions like these have been at the heart of Christianity. Over the centuries, they have led to fierce debate and produced deep divisions among the faithful. These questions have driven profound acts of faith and worship and incited war and persecution. They have contributed to the building of nations and the shaping of lives and have deeply influenced some of the greatest thinkers of Western philosophy. To ponder questions like these is to understand the very shape of the Western world and to comprehend the remarkable power Christian faith has in the life of believers.Now, in The History of Christian Theology, you have an opportunity to explore these profound questions and the many responses believers, scholars, and theologians have developed over more than 2,000 years. Through this 36-lecture course, award-winning Professor Phillip Cary of Eastern University reveals the enduring power of the Christian tradition—as both an intellectual discipline and a spiritual path.Through this course, you will gain thought-provoking insights into a set of teachings that changed the world and discover how, by learning about the diverse beliefs and practices within the wider Christian community, you can enrich your own experience of this great faith.

    These “pagans” were actually pious Greeks, Romans, Syrians, and Gauls who observed the traditions of their ancestors. To these devout polytheists, Christians who worshipped only one deity were immoral atheists who believed that a splash of water on the deathbed could erase a lifetime of sin.Religious scholar James J. O’Donnell takes us on a lively tour of the Ancient Roman world through the fourth century CE, when Romans of every nationality, social class, and religious preference found their world suddenly constrained by rulers who preferred a strange new god. Some joined this new cult, while others denied its power, erroneously believing it was little more than a passing fad.In Pagans, O’Donnell brings to life various pagan rites and essential features of Roman religion and life, offers fresh portraits of iconic historical figures, including Constantine, Julian, and Augustine, and explores important themes—Rome versus the east, civilization versus barbarism, plurality versus unity, rich versus poor, and tradition versus innovation—in this startling account.

    And in this bold 24-lecture series, you can do just that.

    As catchy as that aphorism is, it's sadly untrue, even if it has a nice ring to it. The one thing Nero is well-known for is the one thing he actually didn't do. But fear not, the truth of his life, his rule and what he did with unrestrained power, is plenty weird, salacious and horrifying. And he is not alone. Roman history, from the very foundation of the city, is replete with people and stories that shock our modern sensibilities. Evil Emperors puts the worst of Rome's rulers in one place and offers a review of their lives and a historical context for what made them into what they became. It concludes by ranking them, counting down to the worst ruler in Rome's long history. Lucius Tarquinius Suburbus called peace conferences with warring states, only to slaughter foreign leaders; Commodus sold offices of the empire to the highest bidder; Caligula demanded to be worshipped as a god, and marched troops all the way to the ocean simply to collect seashells as "proof" of their conquest; even the Roman Senate itself was made up of oppressors, exploiters, and murderers of all stripes. Author Phillip Barlag profiles a host of evil Roman rulers across the history of their empire, along with the faceless governing bodies that condoned and even carried out heinous acts. Roman history, deviant or otherwise, is a subject of endless fascination. What's never been done before is to look at the worst of the worst at the same time, comparing them side by side, and ranking them against one another. Until now.
