For nearly 2,000 years, the Christian faith has remained at or near the center of Western moral debate and conceptions of human identity, just action, and ultimate meaning. It has both shaped history and responded to history, showing an extraordinary adaptability within greatly differing cultures. Its practice and influence appears inevery land and every language, and one-third of humanity now affiliates in some way with Christianity.How did this happen? How did a persecuted sect in 1st-century Palestine rise to command such a massive influence on human culture, imagination, and spirit? How did Christianity weather the first critical stages of its historical development and attain its fundamental and enduring cultural role?Discovering the answers to these questions allows you to understand one of the most significant and integral currents of history, and to correct misconceptions about Christianity’s past; gain deep insight into the origins of Western societies, and to understand the relation of faith to politics, economics, and culture; grasp how Christian institutions, theology, and liturgy originated and developed; better comprehend the cultural present, where 7 out of 10 Americans hold Christian beliefs; and deepen your appreciation of the majestic sweep of history that Christianity’s rise represents.Speaking incisively to all of this and more, The History of Christianity: From the Disciples to the Dawn of the Reformation tells the phenomenal story of Christianity’s first 1,500 years, in all its remarkable diversity and complex dimension.In the company of popular Great Courses Professor Luke Timothy Johnson of Emory University, you follow the dramatic trajectory of Christianity from its beginnings as a “cult of Jesus” to its rise as a fervent religious movement; from its emergence as an unstoppable force within the Roman Empire to its critical role as an imperial religion; from its remarkable growth, amid divisive disputes and rivalries, to the ultimate schism between Eastern Orthodoxy and Western Catholicism; and from its spread throughout the Western world to its flowering as a culture that shaped Europe for 800 years. In 36 enthralling lectures, you meet the towering figures of Christian history, such as Paul of Tarsus, Augustine, the emperor Constantine, and Pope Gregory VII, as well as many other pivotal players—kings, popes, saints, monastic figures, scholars, and mystics. And you delve deeply into the rituals, doctrinal issues, and fascinating theological controversies that defined the faith.The History of Christianity: From the Disciples to the Dawn of the Reformation brings to life a truly epic story, giving you a multilayered knowledge of Christianity’s origins, rise, and civilization-shaping presence in our world. The Forging of a Global FaithAcross the arc of the story, you reckon with the historical and theological milestones that formed Christianity, including these seminal moments: The Jesus movement: Investigate the passionate claims of the first believers to an experience of ultimate, transforming power—and the means by which the movement exploded in the decades following Jesus’s death. Critical challenges to the faith: Witness the early Christians’ implacable commitment to the new religion, creating strong institutional and ideological structures even as they answered persecution through martyrdom and “apologetic” literature. Christianity and empire: Learn how the faith, once it was instated as the official religion by Rome, expanded geographically under imperial authority; how Christian culture developed through architecture, art, and ceremony; and how the religion became fatefully enmeshed in politics in the interface of patriarchs, popes, and emperors from Rome to Constantinople. Great controversies of theology: Dig deeply into the Trinitarian and Christological controversies that divided Christians between the 4th and 7th centuries, centering on differing conceptions of the nature of Christ and fiercely contested in the famous Councils of Nicaea, Ephesus, and Chalcedon. The rupture between East and West: Grapple with the overlapping factors of cultural distance, misunderstandings, political rivalries, and doctrinal disputes that led to the final split between Orthodoxy and Catholicism in the 11th century. The flowering of European Christendom: Experience the extraordinary richness of Christian culture in the Middle Ages, including the complex institution of monasticism, the glory of medieval cathedrals, the birth of universities, and the commanding presence of the papacy.The Rich Diversity of Christian ExperienceIn charting the remarkable rise of Christianity, you uncover the specific social and cultural realities that drove the development of the faith.Early in the course, you locate the birth of the religion—and the movement’s powerful appeal—not in the life of Jesus itself, but in the first Christians’ life-altering experience of the Resurrection. You see how early Christianity was not “one thing,” grasping its startling variety of expression through figures such as the preacher Thecla, who dressed as a man and baptized herself, and in the extreme ascetic practices and ideology of the Marcionist movement.You investigate the origins and deep influence of monasticism, its specific practices and ways of life, and you see how monasticism became the dominant formal expression of medieval Catholicism.You travel the geographic expanse of the Christian world, from Persia and Egypt to Byzantium, Rome, and the British Isles, and you glimpse the lives of ordinary Christians in all eras, from the first, embattled Christian communities in Palestine to the sophisticated Catholic culture of the Middle Ages.Faith, Politics, and CivilizationIn the course’s middle section, the formerly countercultural faith becomes the pillar of the world’s greatest military and political power. Here you grapple with the tensions and challenges of this new role, as the Roman Empire “converts” and pagan sacrifice is declared high treason. You track the rivalries of patriarchal centers, as the cities of Antioch, Alexandria, and Constantinople vie for supremacy within the imperial faith. In Byzantium, you witness the increasing intermingling of faith and politics, as the bishop Ambrose of Milan demands public repentance of the brutal emperor Theodosius I, and the emperor Justinian intervenes between factions contesting the true nature of Christ. In the “Carolingian Renaissance” of 9th-century Europe, you see how the emperor Charlemagne responded to papal patronage by sponsoring ecclesiastical reforms and supporting the Latin Mass. And you observe how the papacy—aided by royalty and monk-missionaries—became the central force in bringing the Christian message to all of Europe. Extraordinary Treasures of Christian CultureThroughout the course you observe the profoundly literary quality of this faith, taking note of the diverse Christian writings in Syriac, Coptic, and Armenian, the formulation of Christian orthodoxy in the works of Tertullian and Irenaeus,the philosophical treatises of Clement and Origen, and the scholastic theology of Abelard and Thomas Aquinas.You study the long and colorful development of Christian liturgy in the traditions of ritual, architecture, and public works. You taste the splendor and sensuality of Eastern Orthodox worship, with its ornate vestments, incense, and processions. You learn how the medieval cathedral embodied allegorical symbolism in its form, with its vaulted nave (from navis, “ship”) shaped as an inverted “ship of salvation.” And you observe the role of Christian art in the long conflict in Byzantium over the veneration of religious icons.Finally, you witness the flourishing of contemplative mysticism in the dark era of the Inquisition, and you uncover the misuses of doctrine and forms of corruption that roused the first courageous reformers, boldly anticipating the Protestant Reformation of the 16th century. A Story for the Ages, Masterfully ToldIn recounting the astonishing narrative of Christianity’s unfolding, Professor Johnson draws on his own background as a passionate participant in this tradition, both as a former Benedictine monk and as a world-class scholar. In his powerful and evocative words, this grand tapestry of history comes vibrantly alive as he takes you to the defining moments of Christianity’s past.In The History of Christianity: From the Disciples to the Dawn of the Reformation, you’ll look deeply into the nature and role of faith, the ethos of our civilization, and the core conceptions of identity and ethics that underlie the Western worldview. This is history in the most vivid and meaningful sense of the word: an inquiry into the past that opens a compelling awareness of our present—of our living origins, our ultimate horizons, our deeper selves.

    Classic stories and poems of American literature are found in the pages of Franklin, Emerson, Thoreau, Hawthorne, Melville, Dickinson, Twain, Whitman, Faulkner, James, Eliot, Fitzgerald, Hemingway, Steinbeck, Morrison, and many others. As Professor Arnold Weinstein reminds us: "American classics are wonderfully rich fare. America is a mythic land, a place with a sense of its own destiny and promise, a place that has experienced bloody wars to achieve that destiny. The events of American history shine forth in our classics." When was the last time you read them? Possibly not as recently as you'd like. Why? Not because you wouldn't love it. But perhaps the demands of your daily life or some other reason have prevented this pleasure. Now, here is the opportunity to gain an extraordinary familiarity with each of these authors within a manageable amount of time, as well as review the great works you may already know. What Explains Greatness? These works are both American and classics. The course has been crafted to explain why some works become classics while others do not, why some "immortal" works fade from our attention completely, and even why some contemporary works now being ignored or snubbed by critics may be considered immortal one day. One memorable work at a time, you'll see how each of these masterpieces shares the uncompromising uniqueness that invariably marks the entire American literary canon. From Sleepy Hollow to The Great Gatsby, Professor Weinstein contends that the literary canon lives, grows, and changes. What links these writers to each other—and to us readers today—is the awareness that the past lives and changes as generations of writers and readers step forward to interpret it anew. The course was born from Professor Weinstein's conviction that American literature is our "great estate," and that claiming this rightful inheritance—the living past and the lessons we can take from it—should be nothing less than a unique and joyous learning experience. Experience Two Centuries of America's Greatest Works Professor Weinstein explains that America's classic works should be savored as part of our inner landscape: part of how we see both America and ourselves. He leads you through more than two centuries of the best writers America has yet produced, bringing out the beauty of their language, the excitement of their stories, and the value in what they say about life, power, love, adventure, and what it means, in every sense, to be American. Perhaps you recall: --Melville's prowling Ahab, on the search for Moby Dick, and the power of the "grand, ungodly, Godlike man" --The quiet diner in The Grapes of Wrath and the pain of one of John Steinbeck's "Okies" trying to purchase a dime's worth of bread. --The parlor in Long Day's Journey Into Night and the lifetime of tension in a simple request to a father that he turn on the lights. Rip Van Winkle falls asleep for 25 years for some mysterious reason—but what exactly was it? Why did Emerson believe in self-reliance, and why do we? Twain, our first media celebrity, tells stories that have an inkling of Peter Pan: Tom Sawyer never does grow up. But Huck Finn must grow up to face the racism of the South and get past his own polluted conscience—can he do it? James brings American innocents to Europe for them to inherit the world—but do they? Discover the Stories behind America's Immortal Writers Consider that: --Emily Dickinson was virtually unheard of in her own time. --William Faulkner's books were out of print until the mid-1940s. --F. Scott Fitzgerald died believing he had been forgotten. Readers of their times would be astounded if they knew the immortality these writers achieved, just as we are astounded that they once were overlooked. Most of us don't know that when Walt Whitman self-published Leaves of Grass—seemingly in answer to Ralph Waldo Emerson's memorable wish for the poet America deserved—he sent a copy to Emerson, America's most revered man of letters. When Emerson replied in extraordinarily flattering terms, Whitman published his letter, virtually forcing the new poet's acceptance by a literati that would might have preferred to flee from Whitman's startlingly new, often sexual, poetry. Perhaps you share the common picture of Emily Dickinson: a passive, gentle, reclusive spinster content in her father's Amherst, Massachusetts, home. If so, allow Professor Weinstein to introduce you to her friend, clergyman and author Thomas Wentworth Higginson, who said of "gentle" Emily: "I never was with anyone who drained my nerve power so much. Without touching her, she drew from me. I am glad not to live near her." Through this course, you will learn to: --Explain the roles of self-reliance and the "self-made man" in the evolution of American literature --Identify the tenets of American Romanticism --Describe the evolution of the American ghost story, from Poe and Hawthorne to James and Morrison --Outline the epic strain in American literature, from Melville and Whitman to Faulkner and Ellison --Explain the importance of slavery as a critical subject for Stowe, Twain, Faulkner, and Morrison --Summarize perspectives on nature revealed in poets Whitman, Dickinson, Frost, and Eliot --Identify the tenets of Modernism in the work of Eliot, Fitzgerald, Hemingway, and Faulkner --Identify the contributions of O'Neill, Miller, and Williams to American theater --Summarize the threads of the complex relationship between America's great writers and the past. Savor the Joy of Great ReadingDr. Weinstein is the Edna and Richard Salomon Distinguished Professor at Brown University, where he has been teaching literature to packed classrooms since 1968. Brown University student course evaluation summaries reported: "By far, students' greatest lament was that they only got to listen to Professor Weinstein once a week." One customer writes: "Professor Weinstein is inspiring. Not only am I enjoying these lectures, but I am also rereading these wonderful classics and having a wonderful time." The course will lead you to read or reread masterpieces that intrigue you most. And with the deeper understanding you gain from the lectures, you will likely experience such joy from great reading that you may wonder why you have spent so much time on contemporary books. The 84 carefully crafted lectures in this course, each 30 minutes long, are your royal road to recapturing the American experience—and our intellectual and cultural heritage. Just review the lecture titles. All of this can be yours, and the journey will be as rewarding as the arrival.

    And of a nation that fought a Civil War that freed its slaves, and outlawed segregation and discrimination.This is history shaped by Revolutionary War and Vietnam, Thomas Jefferson and William Jefferson Clinton, Puritanism and Feminism, Booker T. Washington and Martin Luther King, Jamestown and Disneyland, Harpers Ferry and Henry Ford, oil wells and Orson Welles.This is a review of the extraordinary blend of people, ideas, inventions, and events that comprise The History of the United States. In this seven-part, 84-lecture series, three noted historians and lecturers—two of whom teach other popular Teaching Company courses—present the nation's past through their areas of special interest.

    Boston College professor Peter Kreeft delivers a course addressing some of the questions man has been asking since the beginning of time. What is good? What is bad? Why is justice important? Why is it better to be good and just than it is to be bad and unjust?

    While we’re predisposed to look on death with fear and sadness, it’s only by confronting and exploring death head-on that we can actually embrace the important role it plays in our lives. Death, it turns out, is a powerful teacher, one that can help us think responsibly and deeply about the meaning and value of life, connect with the beliefs and traditions of cultures and faiths different from our own, and gain the wisdom and guidance to live a richer, more fulfilling life while we have it.As religion scholar and award-winning Professor Mark Berkson of Hamline University says, “Reflecting on death and dying is an essential part of the examined life.” Take a wide-ranging look at this undeniably confounding and fascinating subject. Bringing together theology, philosophy, biology, anthropology, literature, psychology, sociology, and other fields, these 24 lectures are a brilliant compendium of how human beings have struggled to come to terms with mortality. You’ll encounter everything from ancient burial practices, traditional views of the afterlife, and the five stages of grief to the question of killing during wartime, the phenomenon of near-death experiences, and even 21st-century theories about transcending death itself. Prepare for a remarkable learning experience that brings you face-to-face with the most important topic mortals like us can consider.

    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.

    Much has been written to assess his lasting legacy and why he has had such a profound impact on 20th-century readers.As well as delving into the plots of Lewis's enduring works, you will consider questions such as:From the magisterial "Oxford History of English Literature" to children's fantasy books, how did Lewis write with such brilliance and coherence across so many distinct and demanding fields?What were the people, events, and influences that shaped his thought, his character, and the spiritual drama at his life's core?What do Lewis's fictional and factual autobiographies reveal about his conversion and his efforts to "explain and defend the belief that has been common to nearly all Christians at all times"?How did he argue for his ethical notion of "the Tao"—a non-relative set of standards, held widely across all cultures, which modern ideologies often distort?How did he use his apologetical writings to come to grips with perennial spiritual questions involving miracles; the meaning of suffering; the reality of heaven and hell; and the nature of choice, sin, and salvation?How do his scholarly works analyze modern prejudices about the past and offer a vivid, accessible defense of medieval and Renaissance thought?In Lectures 7 through 11, we turn to Lewis the fictional novelist:The unfallen world of Perelandra in the Space Trilogy (1938–45)The beloved Chronicles of Narnia (1950–1956) children's series for which he is perhaps best knownTill We Have Faces (1961), a mature and beautiful reworking of the Cupid and Psyche myth whose heroine is patterned after Lewis's wife, Joy.Professor Louis Markos is a member of Phi Beta Kappa and has won teaching awards at both the University of Michigan and Houston Baptist University. He presents this course as a sympathetic, deeply felt exposition of Lewis's multifaceted thought and works, making no secret of the fact that he is a longtime and enthusiastic fan of Lewis's writings.

    Yet all too often, we're exposed to information and techniques that promise quick and easy results but can be harmful to your overall health: crash diets, experimental medications, ever-changing studies on what you should eat more or less of, and more. It can be confusing to dig through the mass of hype, myth, and misconceptions about good nutrition habits. So in the face of potentially misleading information and aids, where can you find the key to nutritional success?The answer: in understanding the concepts, practices, and science behind good nutrition. Once you master the intricate—and undeniably captivating—interaction between what you eat and its effect on your body and mind, you unlock a powerful and scientifically proven tool to use in the quest for maintaining or improving your personal health.Nutrition Made Clear is your opportunity to finally sort through nutrition misconceptions and replace them with hard science you can understand. In 36 in-depth lectures taught by dietitian and award-winning Professor Roberta H. Anding, you explore the fundamentals of good nutrition and get a practical and personal guide to applying these fundamentals to your unique lifestyle.

    Professor Weil introduces you to masterpieces such as Tolstoy's War and Peace, Dostoevsky's Crime and Punishment, Pushkin's Eugene Onegin, Gogol's Dead Souls, Chekhov's The Seagull, Pasternak's Doctor Zhivago, and many other great novels, stories, plays, and poems. In all, you plunge into more than 40 works by a dozen writers, from Aleksandr Pushkin in the 19th century to Aleksandr Solzhenitsyn in the 20th century. You also investigate the origin of Russian literature itself, which traces its lineage back to powerful epic poetry and beautiful renderings of the Bible into Slavic during the Middle Ages. All of these works are treated in translation, but Professor Weil does something very unusual in the literature-in-translation arena. For almost every passage that he quotes in English, he reads an extract in the original Russian, with a fluent accent and an actor's sense of drama.

    Schama, the author of the highly acclaimed Citizens and The Embarrassment of Riches, is one of the most popular and celebrated historians of our day, and in this magnificent work he brings history to dramatic life with a wealth of stories and vivid, colorful detail, reanimating familiar figures and events and drawing them skillfully into a powerful and compelling narrative. Schama's perspective moves from the birth of civilization to the Norman Conquest; through the religious wars and turbulance of the Middle Ages to the sovereignties of Henry II, Richard I and King John; through the outbreak of the Black Death, which destroyed nearly half of Europe's population, through the reign of Edward I and the growth of national identity in Wales and Scotland, to the intricate conflicts of the Tudors and the clash between Elizabeth I and Mary Queen of Scots. Driven by the drama of the stories themselves but exploring at the same time a network of interconnected themes--the formation of a nation state, the cyclical nature of power, the struggles between the oppressors and the oppressed--this is a superbly readable and illuminating account of a great nation, and its extraordinary history.

    To start building a more straightforward, accurate understanding of current breakthroughs in neuroscience, you have to start by shattering popular brain myths.Each of these 24 lectures takes as its focus a single powerful, prevalent brain myth, and uses it as a launch pad from which to explore myriad topics in neuroscience: decision making, memory, dreams, emotions, neuroplasticity, consciousness, mental illness, and much more.Our memory is an accurate, objective record of the past. Our senses reflect the world as it really exists. Our dreams have hidden meanings. We are only using 10% of our total brain power. Modern technology (including social media) is making us less intelligent. Dr. Viskontas doesn't just settle for obliterating these and other myths. Instead, she replaces them with scientific facts gathered from experiments, research, and case studies. The result is an eye-opening adventure into the latest understanding of why the brain works the way it does.Whatever order you enjoy these lectures in, you'll be left with insights that will help you better determine the hard scientific truths behind the breaking news (and myths) of tomorrow.

    Churchill's most magnificent literary works. Begun during Churchill's 'wilderness years' when he was out of government, first published in 1956 after his leadership through the darkest days of World War II had cemented his place in history and completed when Churchill was in his 80s, it remains to this day a compelling and vivid history.The first volume - The Birth of Britain - tells the story of the formation of the British state, from the arrival of Julius Caesar and the Roman Empire through the invasions of the Vikings and the Normans, the signing of the Magna Carta and establishment of the mother of parliaments to the War of the Roses.

    Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."
