Yet, as the 1700s began, the mysteries of the universe were pondered by "natural philosophers"—the term "scientist" didn't even exist until the mid 19th century—whose explanations couldn't help but be influenced by the religious thought and political and social contexts that shaped their world.The radical ideas of the Enlightenment were especially important and influential. In this course you see how the work of these natural philosophers prepared the way for the more familiar world of science we recognize today.

    A strong gravitational wave will briefly change that distance by less than the thickness of a human hair. We have perhaps less than a few tenths of a second to perform this measurement. And we don’t know if this infinitesimal event will come next month, next year or perhaps in thirty years.In 1916 Einstein predicted the existence of gravitational waves: miniscule ripples in the very fabric of spacetime generated by unfathomably powerful events. If such vibrations could somehow be recorded, we could observe our universe for the first time through sound: the hissing of the Big Bang, the whale-like tunes of collapsing stars, the low tones of merging galaxies, the drumbeat of two black holes collapsing into one. For decades, astrophysicists have searched for a way of doing so…In 2016 a team of hundreds of scientists at work on a billion-dollar experiment made history when they announced the first ever detection of a gravitational wave, confirming Einstein’s prediction. This is their story, and the story of the most sensitive scientific instrument ever made: LIGO.Based on complete access to LIGO and the scientists who created it, Black Hole Blues provides a firsthand account of this astonishing achievement: a compelling, intimate portrait of cutting-edge science at its most awe-inspiring and ambitious.

    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.

    Today, scientists are attempting to measure the entire universe and to determine its origin. Although the methods have changed, the quest to chart the horizons of space and time continues to be one of the great adventures of science.Measuring the Universe is an eloquent chronicle of the men and women– from Aristarchus to Cassini, Sir Isaac Newton to Henrietta Leavitt and Stephen Hawking–who have gradually unlocked the mysteries of "how far" and in so doing have changed our ideas about the size and nature of the universe and our place in it. Kitty Ferguson reveals their methods to have been as inventive as their results were–and are–eye-opening. Advances such as Copernicus's revolutionary insights about the arrangement of the solar system, William Herschel's meticulous creation of the first three-dimensional map of the universe, and Edwin Hubble's astonishing discovery that the universe is expanding have by turns revolutionized our concept of the universe. Connecting centuries of breakthroughs with the political and cultural events surrounding them, Ferguson makes astronomy part of the sweep of history.To measure the seemingly immeasurable, scientists have always pushed the boundaries of the imagination–today, for example, facing the paradox of an ever-expanding universe that doesn't appear to expand into anything. In Kitty Fergeson's skillfill hands, the unimaginable becomes accessible and the splendid quest something we all can share.

    Because it takes time for light to travel, we see more and more distant regions of the universe as they were in the successively greater past. Impey uses this concept—"look-back time"—to take us on an intergalactic tour that is simultaneously out in space and back in time. Performing a type of cosmic archaeology, Impey brilliantly describes the astronomical clues that scientists have used to solve fascinating mysteries about the origins and development of our universe.The milestones on this journey range from the nearby to the remote: we travel from the Moon, Jupiter, and the black hole at the heart of our galaxy all the way to the first star, the first ray of light, and even the strange, roiling conditions of the infant universe, an intense and volatile environment in which matter was created from pure energy. Impey gives us breathtaking visual descriptions and also explains what each landmark can reveal about the universe and its history. His lucid, wonderfully engaging scientific discussions bring us to the brink of modern cosmology and physics, illuminating such mind-bending concepts as invisible dimensions, timelessness, and multiple universes.A dynamic and unforgettable portrait of the cosmos, How It Began will reward its readers with a deeper understanding of the universe we inhabit as well as a renewed sense of wonder at its beauty and mystery.

    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.

    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

    Here Lawrence M. Krauss, himself a theoretical physicist and best-selling author, offers a unique scientific biography: a rollicking narrative coupled with clear and novel expositions of science at the limits. An immensely colorful persona in and out of the office, Feynman revolutionized our understanding of nature amid a turbulent life. Krauss presents that life—from the death of Feynman’s childhood sweetheart during the Manhattan Project to his reluctant rise as a scientific icon—as seen through the science, providing a new understanding of the legacy of a man who has fascinated millions. An accessible reflection on the issues that drive physics today, Quantum Man captures the story of a man who was willing to break all the rules to tame a theory that broke all the rules.
