Almost daily, researchers are recovering lost information that corrects our picture of what had been a misunderstood era. As a result, we know more than ever about the roles women played in medieval life.       What did it mean to be a heroine in the medieval world? As the four subjects of this course make clear, it meant shaping and changing that world. In the monasteries and churches where people prayed, the universities where they wrote and thought, and even on the political map of Europe itself, these women made differences perceived not only in our time, but in theirs. Women of Intellect, Words, and Passion        These lectures are an extraordinary opportunity to study great women of the past in their own words. Professor Wheeler bases her discussions on recently discovered or recovered written records they left behind, from Hildegard's prodigious scholarship to the personal letters of Heloise and detailed transcripts of Joan of Arc's trial.       With these documents as a basis, you will see Heloise (1101-1163) as a forerunner of Europe's new day. Her letters passionately overflow with the new knowledge of her day. With her star-crossed love, Abelard, she invented a new mode of philosophic thought.       Only now are scholars recovering the long, important second half of the story of Heloise as a woman of power after Abelard's death. Her letters show her to be well versed on such topics as Cicero, classical philosophy, Latin poetry, and rhetoric.       She saw the institution of marriage in her day as little more than a commercial transaction, and its duties burdensome, noisy, costly, and dirty. Her letters reveal her desire to be Abelard's "meretrix" (prostitute) rather than his "imperatrix" (empress). In her discussions on Heloise, Professor Wheeler also covers the long debate as to whether Abelard and Heloise's letters to one anotherthe first, first-person record of a love affair in human history are genuine or not.       Hildegard of Bingen, like Heloise a 12th-century abbess, is revealed as the last flowering of antique learning. She lived a dramatic life as a mystic, voluminous writer, and preacher. She was a personal advisor to Emperor Frederick Barbarossa, and her political involvement and passion as an advocate for clerical and imperial reform give her special interest in our day.       Only in the last generation have scholars rediscovered this amazing medieval intellect. Based on her letters, at least four popes and 10 archbishops corresponded with her, not to mention some 100 other individuals notable to history.Among her many writings, her Book of Simple Medicine was an impressive mini-encyclopedia on what we today would call the natural sciences.       But Hildegard is also known as the "holy hypochondriac," subject to disabling migraines. Were her visions delusions, a result of brainstorms caused by chemical imbalances? Women of Action and Legend        Eleanor of Aquitaine (1124-1204), Queen of France and then England, mother of at least 10 children, scandalized her contemporaries and has fascinated us ever since. She accompanied her husband, Louis VII, on the second Crusade, and her exploits are a reminder that women were crusaders not merely camp followers in numbers that rivaled those of men.       You will learnbased on as-yet-unpublished research by Professor Andrew Lewis that Eleanor was probably born in 1124, not 1122 as normally thought. As a physically hearty woman of courage, she provides a way for historians to explore the diverse roles that women played in enabling or resisting the Crusades. This is exciting work that will allow us to understand medieval women outside the context of home and family as agents of sometimes-radical change.       Eleanor's life is so amazing that it is easy to see why she has become the staple of legends. Among those you will consider are whether she passionately adored, then fought endlessly with, her second husband, Henry II of England (all too true); whether she poisoned Henry's mistress, Rosamund (no proof); and whether she held "courts of love" to encourage and engage in amatory liaisons (again, unproven).       Joan of Arc (1412-1431) was the illiterate French peasant girl whom Mark Twain described as the "youngest person of either sex to lead her nation's army before the age of 19." Known as La Pucelle " (the "maid" or "virgin"), she lacked any kind of military training, yet her military instincts seemed impeccable. Although she carried a sword in battle, she never used it to kill a man, and seems never to have become used to the sight of dead or dying men.Was this young woman who heard heavenly voices an incomprehensible quirk, or did she change the course of European and world history? Ironically, this debate is complicated by the detailed transcripts of her trials, which make her one of the best-documented figures of pre-modern times.       Trial records and her letters reveal her as someone who spoke with "compelling simplicity, quick wit, and piercing honesty." This girl spoke terribly well," said Albert d'Ourches. "I would really like to have had so fine a daughter."       Professor Wheeler dismisses as myth the notions that Joan was actually of noble birth, or that she never fully developed physically as a woman. These lectures reveal Joan as perhaps most memorable for what she was not: a queen, a mother, a beauty, or an intellectual. Instead, she was a woman of action, and the kind of person who is often an enigma to modern intellectuals: someone of profound religious faith.       Appreciating how these four heroines have been understood and misunderstood will help you understand how history passes judgment on both women and the Middle Ages. The contemporary research upon which this course is based can move us beyond how women "ought" to have been to better knowledge, however precarious, about how women were. 24 Lectures 1.

      In 1875, tuberculosis was the deadliest disease in the world, accountable for a third of all deaths. A diagnosis of TB—often called consumption—was a death sentence. Then, in a triumph of medical science, a German doctor named Robert Koch deployed an unprecedented scientific rigor to discover the bacteria that caused TB. Koch soon embarked on a remedy—a remedy that would be his undoing.   When Koch announced his cure for consumption, Arthur Conan Doyle, then a small-town doctor in England and sometime writer, went to Berlin to cover the event. Touring the ward of reportedly cured patients, he was horrified. Koch’s "remedy" was either sloppy science or outright fraud.   But to a world desperate for relief, Koch’s remedy wasn’t so easily dismissed. As Europe’s consumptives descended upon Berlin, Koch urgently tried to prove his case. Conan Doyle, meanwhile, returned to England determined to abandon medicine in favor of writing. In particular, he turned to a character inspired by the very scientific methods that Koch had formulated: Sherlock Holmes.   Capturing the moment when mystery and magic began to yield to science, The Remedy chronicles the stunning story of how the germ theory of disease became a true fact, how two men of ambition were emboldened to reach for something more, and how scientific discoveries evolve into social truths.

    For centuries, the power of zero savored of the demonic; once harnessed, it became the most important tool in mathematics. Zero follows this number from its birth as an Eastern philosophical concept to its struggle for acceptance in Europe and its apotheosis as the mystery of the black hole. Today, zero lies at the heart of one of the biggest scientific controversies of all time, the quest for the theory of everything. Elegant, witty, and enlightening, Zero is a compelling look at the strangest number in the universe and one of the greatest paradoxes of human thought.

    Yet behind that veil lies one of the most amazing civilizations the world has ever known. For most of its 5,000-year existence, China has been the largest, most populous, wealthiest, and mightiest nation on Earth.

This course answers this need by delivering a comprehensive political and historical overview of one of the most fascinating and complex countries in world history.

    He shows that the scientists of ancient and medieval times not only did not understand what we understand about the world—they did not understand what there is to understand, or how to understand it. Yet over the centuries, through the struggle to solve such mysteries as the curious backward movement of the planets and the rise and fall of the tides, the modern discipline of science eventually emerged. Along the way, Weinberg examines historic clashes and collaborations between science and the competing spheres of religion, technology, poetry, mathematics, and philosophy.An illuminating exploration of the way we consider and analyze the world around us, To Explain the World is a sweeping, ambitious account of how difficult it was to discover the goals and methods of modern science, and the impact of this discovery on human knowledge and development.

    It’s because constitutional law is so fundamental to our democracy that law schools across the country teach the subject. It's the area of law that determines what federal and state governments are permitted to do, and what rights you have as an individual citizen of the United States. In these 12 lectures, you'll get the same accessible, well-rounded introduction to constitutional law as a typical law student - but with the added benefit of noted constitutional scholar Eric Berger's brilliant insights. Taking you through all three branches of the federal government, Professor Berger uses some of the most important legal cases in the United States to probe the open-ended nature of the Constitution’s language and illustrate how legal reasoning has defined the power relationships that the Constitution governs. You’ll examine pivotal Supreme Court cases to learn how interpreting the Constitution has radically affected American society. You’ll consider the Supreme Court’s role in deciding - and sometimes avoiding - questions of constitutionality. And you’ll investigate how changes in public opinion can influence how the Supreme Court interprets the Constitution. While the open-ended nature of the Constitution’s language makes constitutional law often uncertain, these lectures offer you a better understanding of its many nuances, as well as its profound importance for the future of the United States.
