Most scientists didn't recognize the import of Hawking's claims, but Leonard Susskind and Gerard t'Hooft realized the threat, and responded with a counterattack that changed the course of physics.The Black Hole War is the thrilling story of their united effort to reconcile Hawking's revolutionary theories of black holes with their own sense of reality -- effort that would eventually result in Hawking admitting he was wrong, paying up, and Susskind and t'Hooft realizing that our world is a hologram projected from the outer boundaries of space.A brilliant book about modern physics, quantum mechanics, the fate of stars and the deep mysteries of black holes, Leonard Susskind's account of the Black Hole War is mind-bending and exhilarating reading.

    Stress is an inherent aspect of life that can have tremendous negative effects on your mental and physical health. This makes coping with stress a critical part of how well we live. Once you understand the inner workings of your stress response system, you'll possess powerful knowledge that will help you understand and better deal with this common aspect of your busy life. Now, from one of the world's foremost researchers on stress and neurobiology, comes a fascinating series of 24 lectures that guide you through the psychological and psychosocial stress that is a central part of everyday life in Western society. You'll learn how the stress-response system is actually a natural survival system-giving, for example, a zebra the best chance to escape from a pursuing lion - that can change from a safety mechanism into a real problem for our physical and mental well-being. You'll see it coming into play against situations it wasn't designed to combat, such as traffic, troublesome thoughts and memories, and concerns over the economy, environment, and international events. And you'll gain valuable insights into how and why stress can affect every part of your body-including your cardiovascular, digestive, and immune systems - and learn about its relationship to important disorders and behaviors, like depression, anxiety, and even addiction.

    Principe on the relation between science and religion from early times to the present.Two crucial forces, science and religion, helped shape Western civilization and continue to interact in our daily lives. What is the nature of their relationship? When do they conflict, and how do they influence each other in pursuit of knowledge and truth? Contrary to prevailing notions that they must perpetually clash, science and theology have actually been partners in an age-old adventure. This course covers both the historical sweep and philosophical flashpoints of this epic interaction.6 audio discs (1 hour each); 68-page course guidebook which includes professor biography, statement of course scope, lecture outlines and notes, a timeline, glossary, biographical notes, and bibliography.Lecture 1.

    Sophisticated beyond the Spaniards' wildest imaginings, these people were the Aztecs, the Maya, and related cultures that shared common traditions of religion, government, the arts, engineering, and trade. In many ways more advanced than European nations, these societies equaled the world's greatest civilizations of their time.Immerse yourself in this epic story with 48 exhilarating half-hour lectures that cover the scope of Mesoamerican history and culture. You'll focus mainly on the Maya, who have been in Mesoamerica for thousands of years, and the Aztecs, who mysteriously appeared late and rose swiftly to power. The Aztecs fell from power just as precipitously; their empire controlled the region for less than a century, until the arrival of the Spanish in the early 1500s. Why were the Aztecs so quickly defeated by the conquistadors, while the Maya resisted the invaders for generations?Although the Spanish eventually conquered all of Mesoamerica, much remains of the original cultures. Beautiful artifacts fill museums. Impressive ruins dot the landscape. And millions of descendants of ancient Mesoamericans still live in their ancestral homes, speaking native languages and practicing time-honored traditions. The countries from Mexico to Costa Rica include more than a dozen UNESCO World Heritage Sites related to the pre-Columbian period, plus scores of other ancient sites that are equally worth a visit. This course is the ideal way to plan an itinerary, prepare for a tour, or simply sit back and enjoy a thrilling virtual voyage. You will be surprised at the number of sites to explore - many more than you could possibly see in months of travel. Your guide is Professor Barnhart, a noted archaeologist whose exploits include the discovery of a lost Maya city.©2015 The Great Courses (P)2015 The Teaching Company, LLC

    It ranges from the study of the universe itself to the smallest particles of matter contained within it - and everything in between. It explores everything from the big bang to theories about the end of the universe. If you want to better understand our physical world, as most of us do, gaining a basic understanding of science itself is profoundly important - yet many are intimidated by the breathtaking scope of such an endeavor. Now an award-winning science teacher has taken out the intimidation, harnessing that breathtaking scope into a series of 60 exciting, comprehensive, and accessible lectures that let you explore and understand the wealth of ideas, discoveries, and principles in all of the physical and biological sciences. You learn that understanding science comes from understanding not only its component disciplines - each of which has its own theories, pioneers, problems, and fundamental questions - but of knowing how these disciplines work with one another to create an entire mosaic of human knowledge. The lectures have been crafted to make those relationships crystal-clear, with an integrated approach that takes you through all of the major disciplines that fall under the umbrella of "science," including physics, chemistry, Earth science, geophysics, and biology. Each lecture covers one of the 60 fundamental principles of the scientific world - offering you new knowledge and insight into topics such as the scientific method, gravitation, atoms, the big bang, plate tectonics, volcanoes, proteins, ecosystems, and electricity.

    What makes evolution such a profoundly provocative concept, so convincing to most scientists, yet so socially and politically divisive? The Theory of Evolution: A History of Controversy is an examination of the varied elements that so often make this science the object of strong sentiments and heated debate. Professor Edward J. Larson leads you through the "evolution" of evolution, with an eye toward enhancing your understanding of the development of the theory itself and the roots of the controversies that surround it. In these lectures you will: Explore pre-Darwinian theories of the origins of life, from Genesis and the ancient Greeks to such 18th- and 19th-century scientists as Georges Cuvier and Chevalier de Lamarck Follow the life and work of Charles Darwin, and the impact of his 1859 masterpiece, On the Origin of Species. Darwin's theory of evolution by natural selection was immediately recognized as a threat to traditional religion, but was quickly accepted (the first printing of Origin of Species sold out on the first day) Examine the history of evolutionary science after Darwin-a fascinating story that includes the "rediscovery," after 35 years, of Gregor Mendel's work on genetic variation; the unearthing of prehominid, or early human, fossils by Raymond Dart in 1925 and the Leakey family in the 1950s; and the confusion created by the sensational, but later discredited, discovery of Piltdown Man-a fake evolutionary "missing link"-in 1912 Trace the history of religious objections to evolution, from those of Darwin's own time to contemporary efforts to teach creation science in American schools. This includes a detailed discussion of the famous Scopes "monkey trial," which in fact was a staged media event, designed to create publicity for the town of Dayton, Tennessee. Are Our Genes more Important than We Are? This course makes it clear that the history of controversy surrounding evolution is not limited to a dispute between science and religion. Even within the scientific community, the fine details of the theory of evolution have long been a matter of passionate dispute. In fact, in the last third of the 19th century, the principal objections were scientific, not religious. Although the fossil record was a key piece of evidence for evolution, it had gaps that could be used to argue against the theory. And both proponents and critics wondered how altruistic human qualities such as love and generosity could possibly have evolved through the competitive, often harsh, processes that Darwin described. From Professor Larson's presentation, you will learn that new ideas in evolution science have often created new controversies. For example, is it truly possible, as some scientists now maintain, that humans exist merely to ensure the survival of their genes? Such research has created disagreement among scientists about the degree to which evolution drives human behavior, and has further alienated many segments of the public. Evolution's "Dark Side": Social Darwinism In these lectures, you will review perhaps the most sinister controversy associated with the theory of evolution: social Darwinism. From the beginning, the Darwinian theory of evolution has been linked to economic and political views. Thomas Malthus's theories of population growth and competition for limited resources even inspired Darwin's thinking on natural selection. Unfortunately, later supporters of evolution carried this line of thinking too far. Beginning with Herbert Spencer, who coined the term "survival of the fittest," Darwin's ideas were used as evidence for a wide range of social beliefs, from laissez-faire capitalism to racism, colonialism, and, in perhaps the worst application, Nazism. In the United States, social Darwinism has served as a basis for the creation of IQ tests and for eugenics programs that resulted in the forced sterilization of thousands of mentally ill or retarded Americans. Unsettling Implications: The Growing Gulf Between Science and Religion During the late 19th century, largely through the efforts of scientists who sought to integrate evolutionary science with spiritual belief, evolution was widely accepted by the religious community in the United States. Today, this is hardly the case. In his last four lectures, Professor Larson examines the trends that have, since 1920, widened the gulf between science and religion. These include an increase in fundamentalist Protestantism, the weakening of liberal Protestantism as a counteracting force, and the growing power of a firmly conservative South. In the 1960s, federally funded neo-Darwinian textbooks provoked a conservative backlash. Beginning with the publication of Henry M. Morris's The Genesis Flood, efforts to gain equal time for the teaching of creation science, based on biblical teachings, gathered strength. Rebuffed by the courts, creationism continues to thrive through the increasing numbers of private Christian schools and through home schooling. The growing gulf between science and religion has unsettling implications for our society. Large segments of the American population reject the naturalism of current evolutionary thinking. Nine of 10 Americans believe in spiritual causes for life, with only 10 percent accepting the purely naturalistic explanations espoused by evolution. Strikingly, these statistics are almost exactly the opposite among the scientific community. A Pulitzer Prize-Winning Teacher As both a historian of science and a professor of law, Professor Edward J. Larson brings exceptional qualifications to this subject. His book, Summer for the Gods: The Scopes Trial and America's Continuing Debate Over Science and Religion, won the 1998 Pulitzer Prize in History. His analysis provides an invaluable perspective on the volatile history of what is arguably the single most significant idea of modern times.

    These include tipping points, the sociological term used to describe moments when unique or rare phenomena become more commonplace; the wisdom of crowds, the argument that certain types of groups harness information and make decisions in more effective ways than individuals; six degrees of separation, the idea that it takes no more than six steps to find some form of connection between two random individuals; and emergence, the idea that new properties, processes, and structures can emerge unexpectedly from complex systems.

    Their work has uncovered a number of the universe’s more surprising secrets, and many believe further wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, astrophysicist Pedro Ferreira brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma, fueling a century of intellectual struggle and triumph.. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics, yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Despite these pitfalls, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. We are in the midst of a momentous transformation in modern physics. As scientists look farther and more clearly into space than ever before, The Perfect Theory reveals the greater relevance of general relativity, showing us where it started, where it has led, and where it can still take us.

    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.

    Roger Penrose—one of the most innovative mathematicians of our time—turns around this predominant picture of the universe’s “heat death,” arguing how the expected ultimate fate of our accelerating, expanding universe can actually be reinterpreted as the “Big Bang” of a new one.Along the way to this remarkable cosmological picture, Penrose sheds new light on basic principles that underlie the behavior of our universe, describing various standard and nonstandard cosmological models, the fundamental role of the cosmic microwave background, and the key status of black holes. Ideal for both the amateur astronomer and the advanced physicist—with plenty of exciting insights for each—Cycles of Time is certain to provoke and challenge.Intellectually thrilling and accessible, this is another essential guide to the universe from one of our preeminent thinkers.

    One thing, however, is clear: Sleep is just as essential to life as nutrition and exercise. This course examines the latest research on the crucial phenomenon of sleep.

    Growing up in a working-class Long Island family, Massimino catapulted himself to Columbia and then MIT, only to flunk his qualifying exams and be rejected twice by NASA before making it to the final round of astronaut selection—where he was told his poor eyesight meant he’d never make the cut. But even that couldn’t stop him from finally earning his wings, making the jump to training in T-38 Air Force jets and preparing his body—and soul—for the journey to the cosmos.Taking us through the surreal wonder and beauty of his first spacewalk, the tragedy of losing friends in the Columbia shuttle accident, and the development of his enduring love for the Hubble telescope—which he’d be tasked with saving on his final mission— Massimino has written an ode to never giving up and the power of teamwork to make anything possible. Spaceman invites us into a rare, wonderful world where the nerdiest science meets the most thrilling adventure, and pulls back a curtain on just what having “the right stuff” really means.

    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

    . . . Readers will never again look into the night sky the same way.” —MICHAEL SHERMER, author of The Believing Brain on Parallax: The Race to Measure the CosmosIn 1930, Edwin Hubble announced the greatest discovery in the history of astronomy since Galileo first turned a telescope to the heavens. The galaxies, previously believed to float serenely in the void, are in fact hurtling apart at an incredible speed; the universe is expanding. This stunning discovery was the culmination of a decades-long arc of scientific and technical advancement. In its shadow lies an untold, yet equally fascinating, backstory whose cast of characters illuminates the gritty, hard-won nature of scientific progress.The path to a broader mode of cosmic observation was blazed by a cadre of 19th-century amateur astronomers and inventors, galvanized by the advent of photography, spectral analysis, and innovative technology to create the entirely new field of astrophysics. From William Bond, who turned his home into a functional observatory, to John and Henry Draper, a father and son team who were trailblazers of astrophotography and spectroscopy, to geniuses of invention such as Léon Foucault, and George Hale, who founded the Mount Wilson Observatory, Hirshfeld reveals the incredible stories—and the ambitious dreamers—behind the birth of modern astronomy.Alan Hirshfeld, Professor of Physics at the University of Massachusetts Dartmouth and an Associate of the Harvard College Observatory, is the author of Parallax: The Race to Measure the Cosmos, The Electric Life of Michael Faraday, and Eureka Man: The Life and Legacy of Archimedes.
