Central to many spiritual and philosophical traditions and known in English as "meditation," these practices are considered a major means for enhanced awareness and self-mastery. In recent decades, modern science has dramatically confirmed what advanced meditators have long claimed—that meditation, correctly practiced, offers deep and lasting benefits for mental functioning and emotional health, as well as for physical health and well-being.

    While they're at it, they helpfully demystify many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, they invite us to see the universe as a vast expanse of mostly uncharted territory that's still ours to explore.This entertaining illustrated science primer is the perfect book for anyone who's curious about all the big questions physicists are still trying to answer.

    (B) Scientific knowledge is always provisional and tells us nothing that is universal, necessary, or certain about the world. Welcome to the science wars—a long-running battle over the status of scientific knowledge that began in ancient Greece, raged furiously among scientists, social scientists, and humanists during the 1990s, and has re-emerged in today's conflict between science and religion over issues such as evolution.Professor Steven L. Goldman, whose Teaching Company course on Science in the 20th Century was praised by customers as "a scholarly achievement of the highest order" and "excellent in every way," leads you on a quest for the nature of scientific reasoning in this intellectually pathbreaking lecture series, Science Wars: What Scientists Know and How They Know It.Those who have taken Professor Goldman's previous course, which is an intensive survey of the revolution in scientific knowledge from 1900 to 2000, may have wondered: if what counts as scientific knowledge can transform so dramatically within only 100 years, what exactly is scientific knowledge? Science Wars addresses this surprisingly difficult question.Five Centuries of the Science WarsIn 24 half-hour lectures, Science Wars explores the history of competing conceptions of scientific knowledge and their implications for science and society from the onset of the Scientific Revolution in the 1600s to the present. It may seem that the accelerating pace of discoveries, inventions, and unexpected insights into nature during this period guarantees the secure foundations of scientific inquiry, but that is far from true. Consider these cases:The scientific method: In the 1600s the English philosopher Francis Bacon defined the scientific method in its classic form: the use of inductive reasoning to draw conclusions from an exhaustive body of facts. But "no scientist has ever been a strict Baconian," says Professor Goldman. "If you followed that, you would get nowhere."A "heated" debate: Around 1800 the dispute over the nature of heat was resolved in favor of the theory that heat is motion and not a substance given off during burning. But then the French mathematical physicist Joseph Fourier wrote a set of equations that accurately described how heat behaves regardless of what it "really" is, which, Fourier contended, was not a scientific question at all.Paradigm shifts: The publication in 1962 of Thomas Kuhn's The Structure of Scientific Revolutions precipitated a radical change in attitudes toward scientific knowledge, prompted by Kuhn's insight that science is not an entirely rational enterprise, and that its well-established theories (or paradigms) are overturned in a revolutionary, nonlogical process.Postmodern putdown: The postmodern attack on science as a privileged mode of inquiry made some headway in the late 20th century. But the credibility of the movement wilted in 1996, when a postmodern journal unwittingly published a spoof by physicist Alan Sokal, purporting to prove that physical theory was socially constructed. Sokal then exposed his piece as a parody.In the penultimate lecture of the course, Professor Goldman considers intelligent design—the argument that evolution can't account for the immense complexity of life and that a master designer must be at work. He approaches this topical debate by asking: What are the minimum criteria that define a hypothesis as scientific, and does intelligent design qualify? Having already covered five centuries of the science wars in the previous lectures, you will analyze this controversy with a set of tools that allows you to see the issues in a sharp, new light.What Is Reality?"Fasten your seatbelts," says Professor Goldman at the outset of Lecture 21—an advisory that applies equally to the whole course, which covers an astonishing array of ideas and thinkers. Throughout, Professor Goldman never loses his narrative thread, which begins 2,400 years ago with Plato's allegorical battle between "the gods" and "the earth giants"—between those for whom knowledge is universal, necessary, and certain; and those for whom it cannot be so and is based wholly on experience.The problem of what constitutes scientific knowledge can be illustrated with one of the most famous and widely accepted scientific theories of all time, Nicolaus Copernicus's heliostatic (stationary sun) theory of the solar system, which has undergone continual change since it was first proposed in 1543: Copernicus called for the planets to move in uniform circular motion around the sun, slightly displaced from the center. Using observations by Tycho Brahe, Johannes Kepler revised the Copernican model, discarding the ancient dogma of circular motion, which did not fit the data. Instead, he guessed that the planets in fact move in elliptical orbits. In his influential work endorsing the Copernican theory, Galileo ignored Kepler's corrections and opted for circular motion. Notoriously, the Catholic Church condemned Galileo for heresy. But the church was actually correct that he had no basis for claiming the heliocentric theory was true, rather than simply an interpretation of experience. Galileo's picture of space was superseded by Newton's and later by Einstein's, which also will doubtless be revised. Even something as basic as the elliptical motion of the planets is a vast oversimplification. There are no closed curves in space, since the solar system is moving around the center of the galaxy; the galaxy is moving within the local cluster; and the local cluster is also moving. Although we still call the conventional picture of the solar system Copernican astronomy, there is effectively no resemblance between astronomy today and Copernicus's 1543 theory of the heavens. The same is also true of other theories, such as the atomic theory of matter. All scientific theories are in a state of ceaseless revision, which raises the question of what reality "really" is. As the contemporary philosopher of science Mary Hesse has pointed out, the lesson of the history of science seems to be that the theories we currently hold to be true are as likely to be overturned as the theories they replaced!Sharpen Your Understanding of What Science IsThe uncertainty about the status of scientific knowledge and about the objectivity of the scientific enterprise led to a broad assault on science in the late 20th century by sociologists, philosophers, and historians, many connected with the postmodern movement. The lectures covering this attack and the ensuing counterattack by scientists are some of the most thrilling in the course and involve a number of figures whom Professor Goldman knows personally.Of one of the firebrands in this conflict, the late Viennese philosopher of science Paul Feyerabend, Professor Goldman says, "I myself took a seminar with Feyerabend when he was teaching at Berkeley in the early 1960s. … Feyerabend was not really off the wall, although he was often depicted that way. … He too recognized, as everyone must, that after all, science does work and science is knowledge of a sort. It's just not the absolute knowledge that scientists and philosophers have historically claimed that it is."By the time you reach the end of this course, you will understand exactly what science is, and you will be enlightened about a fascinating problem that perhaps you didn't even know existed. "There have been a raft of popular books about what scientists know," says Professor Goldman, "but to the best of my knowledge, there is not a single one of these popular books that focuses centrally on the question of how scientists know what they know."This course serves as that book.Course Lecture Titles1.

    For example, the matter that comprises all stars, planets, and living things turns out to be just a fraction of what actually exists. Moreover, we think that we control our actions, but data analytics can predict, with astonishing accuracy, when we will wake up, what we will buy, and even whom we will marry.The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality. And we have developed the power to alter our own reality in major ways - to defeat diseases, compensate for disabilities, and augment our intellect with computers. Where is that trend going?Experience the thrill of this exciting quest in 36 wide-ranging lectures that touch on many aspects of the ceaseless search for reality. From the birth of the universe to brain science, discover that separating the real from the illusory is an exhilarating intellectual adventure.Scientists and philosophers are not alone in grappling, at an intellectual level, with reality. Some of the most accessible interpretations are by painters, novelists, filmmakers, and other artists whose works not only draw on the latest discoveries but also sometimes inspire them. Explore examples such as Alice in Wonderland, pointillism, cubism, surrealism, and reality TV.And since dealing with reality is an experience we all share, this course is designed for people of all backgrounds.

    With the Big Bang, it went from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from dark matter to black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life. But what happens at the end of the story? In billions of years, humanity could still exist in some unrecognizable form, venturing out to distant space, finding new homes and building new civilizations. But the death of the universe is final. What might such a cataclysm look like? And what does it mean for us? Dr. Katie Mack has been contemplating these questions since she was eighteen, when her astronomy professor first informed her the universe could end at any moment, setting her on the path toward theoretical astrophysics. Now, with lively wit and humor, she unpacks them in The End of Everything, taking us on a mind-bending tour through each of the cosmos’ possible finales: the Big Crunch; the Heat Death; Vacuum Decay; the Big Rip; and the Bounce. In the tradition of Neil DeGrasse’s bestseller Astrophysics for People in a Hurry, Mack guides us through major concepts in quantum mechanics, cosmology, string theory, and much more, in a wildly fun, surprisingly upbeat ride to the farthest reaches of everything we know.

    In the book, Sagan explores 15 billion years of cosmic evolution and the development of science and civilization. Cosmos traces the origins of knowledge and the scientific method, mixing science and philosophy, and speculates to the future of science. The book also discusses the underlying premises of science by providing biographical anecdotes about many prominent scientists throughout history, placing their contributions into the broader context of the development of modern science.The book covers a broad range of topics, comprising Sagan's reflections on anthropological, cosmological, biological, historical, and astronomical matters from antiquity to contemporary times. Sagan reiterates his position on extraterrestrial life—that the magnitude of the universe permits the existence of thousands of alien civilizations, but no credible evidence exists to demonstrate that such life has ever visited earth.

Take an unparalleled look at the influence, history, and greatest works of science fiction with illuminating insights and fascinating facts about this wide-ranging genre. If you think science fiction doesn't have anything to do with you, this course deserves your attention. And if you love science fiction, you can't miss this opportunity to trace the arc of science fiction's evolution, understand the hallmarks of great science fiction, and delve deeply into classics while finding some new favorites.These 24 captivating lectures reveal the qualities that make science fiction an enduring phenomenon that has been steadily gaining popularity. You'll grasp the context and achievements of authors like Arthur C. Clarke, H.G. Wells, Isaac Asimov, Ursula K. LeGuin, and many more. You'll experience the wonder, horror, and incredible imagination of works like Frankenstein, the Foundation series, Stranger in a Strange Land, and dozens of more recent stories as well. You'll also see this genre's influence in movies like Star Wars and TV shows like The Twilight Zone.Science fiction can take us places in time and space where no other form of fiction can - outer space, the far future, alternate universes, unfathomable civilizations. The best science fiction expands our imaginations and makes its mark on our reality. And while few writers would ever claim to predict the future, sometimes authors get it almost eerily right: Gernsback describing radar in 1911, Bradbury describing giant flatscreen TVs in 1951, Gibson inventing "cyberspace" in 1984, and so on.

    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.

    But more than this, there was gravity. After that, all hell broke loose… In A Universe from Nothing, Krauss revealed how our entire universe could arise from nothing. Now, he reveals what that something—reality—is. And, reality is not what we think or sense—it’s weird, wild, and counterintuitive; it’s hidden beneath everyday experience; and its inner workings seem even stranger than the idea that something can come from nothing. In a landmark, unprecedented work of scientific history, Krauss leads us to the furthest reaches of space and time, to scales so small they are invisible to microscopes, to the birth and rebirth of light, and into the natural forces that govern our existence. His unique blend of rigorous research and engaging storytelling invites us into the lives and minds of the remarkable, creative scientists who have helped to unravel the unexpected fabric of reality—with reason rather than superstition and dogma. Krauss has himself been an active participant in this effort, and he knows many of them well. The Greatest Story challenges us to re-envision ourselves and our place within the universe, as it appears that “God” does play dice with the universe. In the incisive style of his scintillating essays for The New Yorker, Krauss celebrates the greatest intellectual adventure ever undertaken—to understand why we are here in a universe where fact is stranger than fiction.

    You learn the points of view your teachers provide, the perspectives that books offer, and the conclusions you draw yourself based on the facts you were given. Hearing different angles on historical events gives you a more insightful, more accurate, and more rewarding understanding of events – especially when a new viewpoint challenges the story you thought you knew.
