    Esposito guides you through the facts and myths surrounding Islam and its more than 1.2 billion adherents. How familiar are you with the world's second largest and fastest-growing religion?Many in the West know little about the faith and are familiar only with the actions of a minority of radical extremists.This course will help you better understand Islam's role as both a religion and a way of life, and its deep impact on world affairs both historically and today. It is important to understand what Muslims believe, and also how their beliefs are carried out privately and publicly as individuals as well as members of a larger community."The focus of this course will be to better understand Islam's role as a religion and as a way of life," says Professor Esposito. "In 12 lectures, moving from Muhammad to the present, from the 7th to the 21st centuries, we will explore Muslim beliefs, practices, and history in the context of its significance and impact on Muslim life and society through the ages, as well as world events today."

    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.

    Modern science demonstrates that this mental hardwiring, traceable to the survival needs of our earliest ancestors, is at the root of many of the psychological and behavioral problems that we face today.For thousands of years, people have used mindfulness practices—techniques to develop awareness of present experience with acceptance—to deal effectively with a wide range of life challenges. And, a large and fascinating body of scientific research now validates the remarkable benefits of mindfulness practice for psychological as well as physical health.But how exactly does mindfulness work, in scientific terms? How can understanding the science and practice of mindfulness improve everyday life? And how can the human brain, whose very functioning gives rise to so many of the problems we struggle with, actually provide a solution?Now, in the 24 fascinating lectures of The Science of Mindfulness, Professor Ronald D. Siegel, a clinical psychologist on the faculty of Harvard Medical School, reveals the science behind mindfulness in compelling detail and demonstrates its application to an extraordinary range of human problems—psychological, social, and medical. You’ll closely examine the neurobiology involved, leaving you with a clear knowledge of the science underlying ancient practices that are now profoundly influencing the contemporary world. And you’ll learn many practical ways you can use mindfulness techniques in your own life.

    Professor Hans-Friedrich Mueller, of Union College in Schenectady, New York, makes this ancient world come alive in 24 lectures with captivating stories of intrigue, artifacts, illustrations, and detailed descriptions from primary sources of intriguing personalities. In the ancient Mediterranean area, religion was not separate from daily life. To the contrary, religion was daily life. The many dozen gods of this ancient world were everywhere, with spirits inhabiting every crack and crevice of life. These polytheists believed they had a strict contract with their deities: If they took care of their gods, their gods would take care of them (or at least not harm them). Consequently, they built extraordinary temples to honor their deities, brought food and wine to them, sacrificed animals for them, and held sacred meals with their gods. In fact, they followed numerous rules and regulations that circumscribed almost all aspects of life both inside and outside the home - anything and everything to keep the gods happy. Consequently, the religious practices of the ancient Mediterranean make a wonderful lens through which to develop a deeper understanding of their world.

    They are where history ends up.”Bill Bryson and his family live in a Victorian parsonage in a part of England where nothing of any great significance has happened since the Romans decamped. Yet one day, he began to consider how very little he knew about the ordinary things of life as he found it in that comfortable home. To remedy this, he formed the idea of journeying about his house from room to room to “write a history of the world without leaving home.” The bathroom provides the occasion for a history of hygiene; the bedroom, sex, death, and sleep; the kitchen, nutrition and the spice trade; and so on, as Bryson shows how each has figured in the evolution of private life. Whatever happens in the world, he demonstrates, ends up in our house, in the paint and the pipes and the pillows and every item of furniture.(front flap)

    How could the ancient people who inhabited this tiny speck of land, the most remote in the vast expanse of the Pacific islands, have built such monumental works? No such astonishing numbers of massive statues are found anywhere else in the Pacific. How could the islanders possibly have moved so many multi-ton monoliths from the quarry inland, where they were carved, to their posts along the coastline? And most intriguing and vexing of all, if the island once boasted a culture developed and sophisticated enough to have produced such marvelous edifices, what happened to that culture? Why was the island the Europeans encountered a sparsely populated wasteland? The prevailing accounts of the island’s history tell a story of self-inflicted devastation: a glaring case of eco-suicide. The island was dominated by a powerful chiefdom that promulgated a cult of statue making, exercising a ruthless hold on the island’s people and rapaciously destroying the environment, cutting down a lush palm forest that once blanketed the island in order to construct contraptions for moving more and more statues, which grew larger and larger. As the population swelled in order to sustain the statue cult, growing well beyond the island’s agricultural capacity, a vicious cycle of warfare broke out between opposing groups, and the culture ultimately suffered a dramatic collapse. When Terry Hunt and Carl Lipo began carrying out archaeological studies on the island in 2001, they fully expected to find evidence supporting these accounts. Instead, revelation after revelation uncovered a very different truth. In this lively and fascinating account of Hunt and Lipo’s definitive solution to the mystery of what really happened on the island, they introduce the striking series of archaeological discoveries they made, and the path-breaking findings of others, which led them to compelling new answers to the most perplexing questions about the history of the island. Far from irresponsible environmental destroyers, they show, the Easter Islanders were remarkably inventive environmental stewards, devising ingenious methods to enhance the island’s agricultural capacity. They did not devastate the palm forest, and the culture did not descend into brutal violence. Perhaps most surprising of all, the making and moving of their enormous statutes did not require a bloated population or tax their precious resources; their statue building was actually integral to their ability to achieve a delicate balance of sustainability. The Easter Islanders, it turns out, offer us an impressive record of masterful environmental management rich with lessons for confronting the daunting environmental challenges of our own time. Shattering the conventional wisdom, Hunt and Lipo’s ironclad case for a radically different understanding of the story of this most mysterious place is scientific discovery at its very best.

    Did nothing happen in between? Determined to find out, he embarks on a journey of rediscovery, following in the footsteps of the many Europeans who preceded the Pilgrims to America.An irresistible blend of history, myth, and misadventure, A Voyage Long and Strange captures the wonder and drama of first contact. Vikings, conquistadors, French voyageurs — these and many others roamed an unknown continent in quest of grapes, gold, converts, even a cure for syphilis. Though most failed, their remarkable exploits left an enduring mark on the land and people encountered by late-arriving English settlers.Tracing this legacy with his own epic trek — from Florida's Fountain of Youth to Plymouth's sacred Rock, from desert pueblos to subarctic sweat lodges, Tony Horwitz explores the revealing gap between what we enshrine and what we forget. Displaying his trademark talent for humor, narrative, and historical insight, A Voyage Long and Strange allows us to rediscover the New World for ourselves.

    airspace on September 11, the population of this small town on Newfoundland Island swelled from 10,300 to nearly 17,000. The citizens of Gander met the stranded passengers with an overwhelming display of friendship and goodwill. As the passengers stepped from the airplanes, exhausted, hungry and distraught after being held on board for nearly 24 hours while security checked all of the baggage, they were greeted with a feast prepared by the townspeople. Local bus drivers who had been on strike came off the picket lines to transport the passengers to the various shelters set up in local schools and churches. Linens and toiletries were bought and donated. A middle school provided showers, as well as access to computers, email, and televisions, allowing the passengers to stay in touch with family and follow the news.Over the course of those four days, many of the passengers developed friendships with Gander residents that they expect to last a lifetime. As a show of thanks, scholarship funds for the children of Gander have been formed and donations have been made to provide new computers for the schools. This book recounts the inspiring story of the residents of Gander, Canada, whose acts of kindness have touched the lives of thousands of people and been an example of humanity and goodwill.

    Whether it’s a friend who can’t quit smoking, a colleague afflicted with alcoholism, or a relative abusing prescription drugs, we all know someone who suffers from some form of addiction—we may even have an addiction ourselves. By some estimates, roughly one in four Americans might be considered addicts. On the other hand, many of us use substances such as alcohol recreationally, without suffering the physical or psychological symptoms of addiction. So what is the difference between drug use, abuse, and clinical addiction? What causes addictions? What happens when your brain is on drugs, and why do addicts behave the way they do?12 Lectures 1.
