From the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day, nothing so pervades our existence and yet is so difficult to explain. Time seems to be woven into the very fabric of the universe. But why? Consider these contrasting views of time: A movie of a person diving into a pool has an obvious arrow of time. When the movie is played backward, everyone recognizes that it shows an event that would never occur in the real world. But zoom in on any part of this scene at the atomic scale and the movie can be run backward or forward and be indistinguishable. Either way, the particle interactions are consistent with the laws of physics. Why does one movie have an arrow of time moving in only one direction and the other does not? Surprisingly, the search for an answer leads through some of the most pioneering fields of physics, including thermodynamics, relativity, quantum theory, and cosmology. The key concept is called "entropy," which is related to the second law of thermodynamics, considered by many scientists to be the most secure law in all of physics. But that's only the beginning, since the quest for the ultimate theory of time draws on such exciting ideas as black holes, cosmic inflation, and dark energy, before closing in on a momentous question that until recently was considered unanswerable: What happened before the big bang? In 24 riveting half-hour lectures, Mysteries of Modern Physics: Time takes you on a mind-expanding journey through the past, present, and future, guided by Professor Sean Carroll, noted author and Senior Research Associate in Physics at the California Institute of Technology.

    But as renowned Yale surgeon and medical historian Sherwin B. Nuland shows in this brilliant collection of linked life portraits, the theory bears little resemblance to the truth. Through the centuries, the men and women who have shaped the world of medicine have been not only very human, but also very much the products of their own times and places. Presenting compelling studies of great medical innovators and pioneers, Doctors gives us a fascinating history of modern medicine. Ranging from the legendary Father of Medicine, Hippocrates, to Andreas Vesalius, whose Renaissance masterwork on anatomy offered invaluable new insight into the human body, to Helen Taussig, founder of pediatric cardiology and co-inventor of the original blue baby operation, here is a volume filled with the spirit of ideas and the thrill of discovery.

    It starts in your mother's womb, accelerates to high speed in infancy and childhood, and continues through every age, whether you're actively engaged in mastering a new skill, intuitively discovering an unfamiliar place, or just sleeping, which is fundamental to helping you consolidate and hold on to what you've learned. You are truly born to learn around the clock.But few of us know how we learn, which is the key to learning and studying more effectively. For example, you may be surprised by the following:People tend to misjudge what they have learned well, what they don't yet know, and what they do and do not need to practice.Moments of confusion, frustration, uncertainty, and lack of confidence are part of the process of acquiring new skills and new knowledge.Humans and animals explore their worlds for the sake of learning, regardless of rewards and punishment connected with success.You can teach an old dog new tricks. In fact, older learners have the benefit of prior knowledge and critical skills—two advantages in learning.Shedding light on what's going on when we learn and dispelling common myths about the subject, How We Learn introduces you to this practical and accessible science in 24 half-hour lectures presented by Professor Monisha Pasupathi of the University of Utah, an award-winning psychology teacher and expert on how people of all ages learn.

    From liberty to democracy to community, the terms and concepts originated by political philosophers are ingrained in our global consciousness. Yet many of us have an incomplete picture of how these ideas developed and, quite possibly, a skewed perception of their intentions and implications.This highly relevant course sheds light on the labyrinth of Western political and social theory, as well as its influence on modern history. Guided by an award-winning professor of philosophy and author, these eye-opening lectures reveal how political philosophers, in responding to the societal problems and changing conditions of their day in revolutionary ways, created virtual blueprints of action for leaders. You'll gain not only the tools to comprehend the omnipresent language of politics, but a thorough understanding of the wellspring of thought that has emerged over centuries of political philosophy and the intellectual origins of major historical movements and events.Throughout, questions of democracy, freedom, and distributive justice are addressed, and revolutionary figures who have left an indelible mark on history - from Niccolo Machiavelli to Ayn Rand - are encountered.By the conclusion of lecture 36, you will have the context necessary to appreciate the evolution of a myriad of political ideas, including hot-button topics of today such as libertarianism, neoconservatism, feminism, and environmentalism.

    He was told—like his entire generation—that his problem was caused by a chemical imbalance in his brain. As an adult, trained in the social sciences, he began to investigate this question—and he learned that almost everything we have been told about depression and anxiety is wrong. Across the world, Hari discovered social scientists who were uncovering the real causes—and they are mostly not in our brains, but in the way we live today. Hari’s journey took him from the people living in the tunnels beneath Las Vegas, to an Amish community in Indiana, to an uprising in Berlin—all showing in vivid and dramatic detail these new insights. They lead to solutions radically different from the ones we have been offered up until now.Just as Chasing the Scream transformed the global debate about addiction, with over twenty million views for his TED talk and the animation based on it, Lost Connections will lead us to a very different debate about depression and anxiety—one that shows how, together, we can end this epidemic.

    Despite the papacy's enormous influence, how much do you really know about this ancient and powerful institution? Catholics and non-Catholics alike will enjoy these 24 illuminating lectures about this remarkable institution. Professor Noble gives you priceless insights into the dramatic history of the papal office and the lives of the men who represented it. You'll follow four critical strands of papal history over 2,000 years: the history of the "Petrine" idea; the history of an institution; the history of popes and antipopes; the history of Western civilization; and you'll look inside the Vatican's doors and discover fresh views on the institution's people, ideas, traditions, and routines, as well as the important roles played by organizations like the Curia and the Secretariat of State. You'll investigate the mechanisms by which the church not only ministers to its worldwide flock but also deals with the practical realities of its administration. Filled with interesting stories and remarkable insights, this course promises to educate, enlighten, and entertain you.Course Lecture Titles:1. What Is Papal History? When Did It Begin?2.

    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. And for us as Westerners, it is essential to understand where China has been in order to anticipate its future. 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.

    

    Fischer surveys anthropology, the study of human societies and comparative customs with a special emphasis on pre-capitalist societies and the things which pre-capitalist societies and modern societies have in common.

    Our memory is unreliable; we can't multiply large sums in our heads; advertising manipulates our judgment; we tend to distrust people who are different from us; supernatural beliefs and superstitions are hard to shake; we prefer instant gratification to long-term gain; and what we presume to be rational decisions are often anything but. Drawing on striking examples and fascinating studies, neuroscientist Dean Buonomano illuminates the causes and consequences of these "bugs" in terms of the brain's innermost workings and their evolutionary purposes. He then goes one step further, examining how our brains function-and malfunction-in the digital, predator-free, information-saturated, special effects-addled world that we have built for ourselves. Along the way, Brain Bugs gives us the tools to hone our cognitive strengths while recognizing our inherent weaknesses.

    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.

    God and Mankind: Comparative Religions by Professor Robert Oden is an ideal starting point for gaining some progress in considering these questions. And if you've been thinking about them for a while, as so many do, you will likely discover he has many fresh insights to offer you.Professor Oden, who holds degrees in Near Eastern Languages and Civilizations, and Theology, has taught at Harvard University and Dartmouth College over a long and exceptionally distinguished career as both teacher and college president.His lectures approach religious belief and ritual as possible answers to these most difficult and enduring questions, which have occupied humanity from the beginning.An Ideal Starting Point for InquiryThe lectures underscore both the unity and the diversity of religious approaches to life in a sweeping conceptual grasp.Professor Oden begins with a discussion of the nature and study of religion, distinguishing between religion as both a matter of faith and as an appropriate subject of intellectual and academic pursuit.In addition to discussing the four traditional views of religion, Professor Oden proposes another: a system of communication.This serves as a crucial conceptual framework for exploring the thoughts of Mircea Eliade, a historian of religion, philosopher, and professor at the University of Chicago, who proposed that the best way to understand religions is to examine their views of how the world came into being and how it operates on a daily basis.How Do We Reconcile Suffering and a Benevolent Deity?Professor Oden continues with an investigation of the problem of reconciling an all-powerful and benevolent deity with the suffering and evil that are part of human existence.You will also look at the dynamics of religious communities in general and the impact of the Puritan religious tradition on America.The introductory lecture lays out a framework for the study of religion, beginning with the "what" and "why" of the matter, and moving to how religions have been compared with history, science, psychology, and society.You learn that for religions such as Hinduism and Buddhism that see the world as old, salvation comes by escaping from the endless cycle of birth and rebirth. But Judaism and Christianity, however, see the world as relatively new, and the goal is to gain more chances at life, either collectively or individually.Professor Oden addresses the centrality of myth in making sense of religious cosmologies, and he places special emphasis on the birth narratives of religious heroes, particularly the unusual circumstances surrounding their conception and birth.Religious Heroes and Teachersin developing a framework for an extensive discussion of the ancient Sumerian myth, the Epic of Gilgamesh and its cosmological implications.You explore the notion of the anthropologist Arnold van Gennep, later expanded by the American anthropologist Victor Turner, that the rite of passage theme must be understood as central for religious cosmologies in general.As with Gilgamesh, this lecture looks at the stories of Moses, Jesus, Krishna, and Gautama the Buddha, unearthing in each a key point that aptly reflects the cosmology of the religion in question.Professor Oden goes into a systematic analysis of the "theodicy" problem, which is: How can an all-powerful and benevolent deity allow innocent people to suffer while often success and happiness seem to come to those who are evil? All world religions have attempted to deal with this dilemma—and five answers have been produced.The discussion of theodicy continues by examining the most famous example in the Western religious tradition—the book of Job—and two of the main sources of Christian thinking on the topic, the Apostle Paul and the 16th-century Swiss theologian, John Calvin.By way of comparison, Professor Oden also discusses the Hindu and Buddhist responses to the theodicy question, including the Hindu doctrines of karmic law and transmigration of souls, and the Buddhist teaching that life is suffering, with the only release an acceptance of the impermanence of the universe and everything in it.Ritual, Sect, and ChurchIn examining ritual, Professor Oden places special emphasis on its nature, importance, and ramifications for the religious community, and then describes the dynamics of the development of two types of religious communities: sect and church.Professor Oden moves from the comparative sociology of religion to what might be termed the religious nature of a particular society: the United States. Drawing on the work of the Harvard scholar Sacvan Bercovitch, the lecture addresses the American identity with reference to its Puritan origins.Taking the theme of America and Americans being "God's elect" and the parallels between America and ancient Israel, Professor Oden proposes an American civil religion whose themes include:The "chosen" history of AmericaA strong notion of covenant, with America's fate emblematic of the world'sThe idea that, in America, the ultimate sovereignty is not the people's, but God's.In conclusion, Professor Oden discusses four aspects of today's American identity that seem to have come directly from the Puritan tradition:An anti-intellectual bias toward individualism rather than collective experience and theoryA bias against ritualThe strongest fundamentalist tradition in the advanced industrialized worldA uniquely American anxiety over vocational and occupational calling that is not found elsewhere in the world.8 lectures | 43 minutes each1 Why Nothing Is as Intriguing as the Study of Religion2 Orienting Humanity—Religions as Spiritual Compasses3 Religious Heroes 1—Gilgamesh and the Dawn of History4 Religious Heroes 2—Moses and Jesus5 Pondering Divine Justice—Do We Suffer for Naught?6 Defending Divine Justice—Religious Accounts of Suffering7 Religious Rituals and Communities8 Bringing It All Back Home

    The Psychopath Test is a fascinating journey through the minds of madness. Jon Ronson's exploration of a potential hoax being played on the world's top neurologists takes him, unexpectedly, into the heart of the madness industry. An influential psychologist who is convinced that many important CEOs and politicians are, in fact, psychopaths teaches Ronson how to spot these high-flying individuals by looking out for little telltale verbal and nonverbal clues. And so Ronson, armed with his new psychopath-spotting abilities, enters the corridors of power. He spends time with a death-squad leader institutionalized for mortgage fraud in Coxsackie, New York; a legendary CEO whose psychopathy has been speculated about in the press; and a patient in an asylum for the criminally insane who insists he's sane and certainly not a psychopath. Ronson not only solves the mystery of the hoax but also discovers, disturbingly, that sometimes the personalities at the helm of the madness industry are, with their drives and obsessions, as mad in their own way as those they study. And that relatively ordinary people are, more and more, defined by their maddest edges.
