The Search for Exoplanets: What Astronomers Know


Joshua N. Winn - 2015
    Thanks to advances in technology and clever new uses of existing data, now we know that planetary systems and possibly even a new Earth can be found throughout galaxies near and far.We are living during a new golden age of planetary discovery, with the prospect of finding many worlds like Earth. Most of the thousands of planets we've detected can't be imaged directly, but researchers are able to use subtle clues obtained in ingenious ways to assemble an astonishing picture of planetary systems far different from our own. We are in the midst of an astronomical revolution, comparable to the Copernican revolution that established our current view of the solar system - and we invite you to take part.Embark on this unrivaled adventure in 24 lectures by a veteran planet hunter. Designed for everyone from armchair explorers to serious skywatchers, The Search for Exoplanets follows the numerous twists and turns in the hunt for exoplanets - the false starts, the sudden breakthroughs, and the extraordinary discoveries. Explore systems containing super-Earths, mini-Neptunes, lava worlds, and even stranger worlds. You also get behind-the-scenes information on the techniques astronomers used to find evidence of planets at mind-boggling distances from our home base. Learn how astronomers determine how many planets are in a system as well as how large they are and the characteristics of their atmospheres. You will feel like Dr. Watson in the presence of Sherlock Holmes as Professor Winn extracts a wealth of information from a spectrum, a light graph, a diffraction pattern, and other subtle clues.©2015 The Teaching Company, LLC (P)2015 The Great Courses

Forensic History: Crimes, Frauds, and Scandals


Elizabeth A. Murray - 2014
    The infamous Jack the Ripper slayings. The alleged survival of Anastasia Romanov, the youngest daughter of the murdered Tsar. Seven-time Tour de France winner Lance Armstrong's public fall from grace. The Chicago Tylenol poisonings and the copycat crimes that followed. Step into the world of forensic science and study the most fascinating crimes and mysteries from the last two centuries in the 24 lectures of Forensic History: Crimes, Frauds, and Scandals . Professor Murray, a forensic anthropologist with nearly 30 years of experience in the field, has crafted lectures that are a remarkable blend of storytelling and science - a whirlwind tour that takes you from the gas-lit streets of Victorian London to small-town America. As you journey around the world and into the past, you'll re-examine modern history's great crimes and scandals using the tools and insights of forensic science. In doing so, you'll learn how cutting-edge advancements in science and technology are applied to investigations and how to evaluate evidence and think like a forensic scientist. Using her extensive background in the field and her skill at weaving riveting stories, Professor Murray invites you peer over the shoulders of investigators as they examine some of the most famous crimes in history, as well as cases that shed light on what happens when the justice system goes awry. Whether they're controversial or by-the-book, solved or unsolved, hot or cold, these cases are an opportunity to gain deeper insight into the historic and cutting-edge methods and tools forensic scientists use on the job. Having participated in hundreds of investigations in America and abroad, Professor Murray intersperses these historical examinations with some of her own, equally intriguing, personal experiences.Please note there is a 293 page book included in this course so please do not Notabook again.

The Era of the Crusades


Kenneth W. Harl - 2000
    From this perspective, you'll study the complex but absorbing causes of the Crusades, which include the many political, cultural, and economic changes in Western Europe after the fall of the Roman Empire. You'll examine the Crusades in terms of the specific military campaigns-the eight "canonical" Crusades that took place from 1095-1291-proclaimed to retake Jerusalem and the Holy Land from Muslim hands and return them to Christendom. You'll consider the immediate circumstances-the leaders, purposes, key battles, and degrees of success or failure-surrounding these often-monumental expeditions.You'll also explore a wide variety of misperceptions and long-debated questions about the Crusades:Did the popes preach the Crusades as a way to increase their personal power and authority?Why did the members of the Fourth Crusade decide to sack Constantinople, turning the Crusades from Christian against "infidel" to Christian against Christian?Taken together, these historically rich lectures are an opportunity to appreciate fully how Western Civilization changed in many profound ways during the Crusading era.

The Renaissance, the Reformation and the Rise of Nations


Andrew C. Fix - 2005
    In this course, you will explore the political, social, cultural, and economic revolutions that transformed Europe between the arrival of the Black Death in the 14th century and the onset of the Age of Enlightenment in the 18th century.

Why Does E=mc²? (And Why Should We Care?)


Brian Cox - 2009
    Breaking down the symbols themselves, they pose a series of questions: What is energy? What is mass? What has the speed of light got to do with energy and mass? In answering these questions, they take us to the site of one of the largest scientific experiments ever conducted. Lying beneath the city of Geneva, straddling the Franco-Swiss boarder, is a 27 km particle accelerator, known as the Large Hadron Collider. Using this gigantic machine—which can recreate conditions in the early Universe fractions of a second after the Big Bang—Cox and Forshaw will describe the current theory behind the origin of mass.Alongside questions of energy and mass, they will consider the third, and perhaps, most intriguing element of the equation: 'c' - or the speed of light. Why is it that the speed of light is the exchange rate? Answering this question is at the heart of the investigation as the authors demonstrate how, in order to truly understand why E=mc2, we first must understand why we must move forward in time and not backwards and how objects in our 3-dimensional world actually move in 4-dimensional space-time. In other words, how the very fabric of our world is constructed. A collaboration between two of the youngest professors in the UK, Why Does E=mc2? promises to be one of the most exciting and accessible explanations of the theory of relativity in recent years.

The Italian Renaissance


Kenneth R. Bartlett - 2005
    But why was there such an artistic, cultural, and intellectual explosion in Italy at the start of the 14th century? Why did it occur in Italy? And why in certain Italian city-states such as Florence? Professor Bartlett probes these questions and more in 36 dynamic lectures. This is your opportunity to appreciate the results of the Italian Renaissance and gain an understanding of the underlying social, political, and economic forces that made such exceptional art and culture possible. At the heart of Renaissance Italy were the city-states, home to the money, intellect, and talent needed for the growth of Renaissance culture. You'll look at the Republic of Florence, as well as other city-states that, thanks to geographical and historical circumstances, had much different political and social structures. This course contains a wealth of details that will give you a feel and appreciation for the Italian Renaissance - its contributions to history, the ways it was similar and dissimilar to our times, and how the people of the time, both famous and ordinary, experienced it. You'll come away surprised by how much of our modern life was made possible by the Renaissance. Our concept of participatory government, our belief in the value of competition, our philosophy of the content and purpose of education, even our notions of love all have roots in the Renaissance period. Its loftiest ideals - the importance of the individual, the value of human dignity and potential, and the promotion of freedom - are ones we embrace as our own.

The History of Spain: Land on a Crossroad


Joyce E. Salisbury - 2017
    To understand the unfolding of Spain's epic history is to come to terms with one of the West's great cultures, and to grasp its enduring presence and impact on the world stage.In these 24 accessible lectures, Professor Salisbury presents a broad and enthralling panorama of Spanish history, covering the centuries from the first prehistoric settlement of the peninsula to Spain's 20th-century civil war.Linking one seminal era with the next, the course begins with how early Spain drew a range of peoples from ancient Africa, the Mediterranean, and the Middle East, who formed vibrant communities on the peninsula. From there, you'll witness the rule of the peninsula by both Rome and Visigothic peoples, leading to the spellbinding drama of Islamic Spain and the Reconquista, Catholic Spain and the Inquisition, and the opening of the New World. Finally, you'll travel into the kingly dynasties and the dazzling artistic heritage of the Habsburgs and Bourbons, and you'll track Spain's emergence into the modern world.Together with the unfolding of Spanish history, Professor Salisbury illuminates Spain's iconic cultural forms - such as flamenco music and dance, and the ritual of bullfighting - and its phenomenal contributions to art, architecture, literature, music, theology, and learning.Across the centuries, you'll explore jewels of Spanish architecture, from the resplendent Moorish Alhambra and Alcázar of Seville to the sublime Sagrada Familia cathedral of modernist Antoni Gaudí. And you'll encounter Spain's geniuses of the visual and written arts, including such masters as the painters Velasquez, el Greco, Goya, and Picasso, and writers from the philosophers Averroes and Maimonides to literary greats Lope de Vega and Cervantes.Travel with us to this remarkable culture, and savor the beauty and the great human drama of the history of Spain.

Our Mathematical Universe: My Quest for the Ultimate Nature of Reality


Max Tegmark - 2012
    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

The Theory of Evolution: A History of Controversy


Edward J. Larson - 2001
    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.

Maya to Aztec: Ancient Mesoamerica Revealed


Edwin Barnhart - 2015
    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

The Story of Human Language


John McWhorter - 2004
    There are good reasons that language fascinates us so. It not only defines humans as a species, placing us head and shoulders above even the most proficient animal communicators, but it also beguiles us with its endless mysteries. For example: * How did different languages come to be? * Why isn’t there just a single language? * How does a language change, and when it does, is that change indicative of decay or growth? * How does a language become extinct? Dr. John McWhorter, one of America’s leading linguists and a frequent commentator on network television and National Public Radio, addresses these and other questions as he takes you on an in-depth, 36-lecture tour of the development of human language, showing how a single tongue spoken 150,000 years ago has evolved into the estimated 6,000 languages used around the world today.An accomplished scholar, Professor McWhorter is also a skilled popularizer, whose book The Power of Babel was called "startling, provocative, and remarkably entertaining," by the San Diego Union-Tribune.The London Times called him "a born teacher." And Steven Pinker, best known as the author of The Language Instinct, offered this praise for the book: "McWhorter’s arguments are sharply reasoned, refreshingly honest, and thoroughly original."Course Lecture Titles1.
