Relativity and quantum physics touch the very basis of physical reality, altering our commonsense notions of space and time, cause and effect. Both have reputations for complexity. But the basic ideas behind relativity and quantum physics are, in fact, simple and comprehensible by anyone. As Professor Wolfson points out, the essence of relativity can be summed up in a single sentence: The laws of physics are the same for all observers in uniform motion. The same goes for quantum theory, which is based on the principle that the "stuff " of the universe-matter and energy-is not infinitely divisible but comes in discrete chunks called "quanta." Profound ... Beautiful ... Relevant Why should you care about these landmark theories? Because relativity and quantum physics are not only profound and beautiful ideas in their own right, they are also the gateway to understanding many of the latest science stories in the media. These are the stories about time travel, string theory, black holes, space telescopes, particle accelerators, and other cutting-edge developments. Consider these ideas: Although Einstein's theory of general relativity dates from 1914, it has not been possible to test certain predictions until recently. The Hubble Space Telescope is providing some of the most striking confirmations of the theory, including certain evidence for the existence of black holes, objects that warp space and time so that not even light can escape. Also, the expansion of the universe predicted by the theory of general relativity is now a known rate. General relativity also predicts an even weirder phenomenon called "wormholes" that offer shortcuts to remote reaches of time and space. According to Einstein's theory of special relativity, two twins would age at different rates if one left on a high-speed journey to a distant star and then returned. This experiment has actually been done, not with twins, but with an atomic clock flown around the world. Another fascinating experiment confirming that time slows as speed increases comes from measuring muons at the top and bottom of mountains. A seemingly absurd consequence of quantum mechanics, called "quantum tunneling," makes it possible for objects to materialize through impenetrable barriers. Quantum tunneling happens all the time on the subatomic scale and plays an important role in electronic devices and the nuclear processes that keep the sun shining. Some predictions about the expansion of the universe were so odd that Einstein himself tried to rewrite the mathematics in order to eliminate them. When Hubble discovered the expansion of the universe, Einstein called the revisions the biggest mistake he had ever made. An intriguing thought experiment called "Schrödinger's cat" suggests that a cat in an enclosed box is simultaneously alive and dead under experimental conditions involving quantum phenomena. From Aristotle to the Theory of Everything Professor Wolfson begins with a brief overview of theories of physical reality starting with Aristotle and culminating in Newtonian or "classical" physics. Then he outlines the logic that led to Einstein's theory of special relativity, and the simple yet far-reaching insight on which it rests. With that insight in mind, you move on to consider Einstein's theory of general relativity and its interpretation of gravitation in terms of the curvature of space and time. Professor Wolfson then shows how inquiry into matter at the atomic and subatomic scales led to quandaries that are resolved-or at least clarified-by quantum mechanics, a vision of physical reality so at odds with our experience that it nearly defies language. Bringing relativity and quantum mechanics into the same picture leads to hypotheses about the origin, development, and possible futures of the entire universe, and the possibility that physics can produce a "theory of everything" to account for all aspects of the physical world. Fascinating Incidents and Ideas Along the way, you'll explore these fascinating incidents and ideas: In the 1880s, Albert Michelson and Edward Morley conducted an experiment to determine the motion of the Earth relative to the ether, which was a supposedly imponderable substance pervading all of space. You'll learn about their experiment, its shocking result, and the resulting theoretical crisis. In 1905, a young Swiss patent clerk named Albert Einstein resolved the crisis by discarding the ether concept and asserting the principle of relativity-that the laws of physics are the same for all observers in uniform motion. Relativity implies that the time order of events can be different in different reference frames. Does this wreak havoc with cause and effect? And why does Einstein assert that nothing can go faster than light? Shortly after publishing his 1905 paper on special relativity, Einstein realized that his theory required a fundamental equivalence between mass and energy, which he expressed in the equation E=mc2. Among other things, this famous formula means that the energy contained in a single raisin could power a large city for a whole day. Historically, the path to general relativity followed Einstein's attempt to incorporate gravity into relativity theory, which led to his understanding of gravity not as a force, but as a local manifestation of geometry in curved spacetime. Quantum theory places severe limits on our ability to observe nature at the atomic scale because it implies that the act of observation necessarily disturbs the thing that is being observed. The result is Werner Heisenberg's famous "uncertainty principle." Are quarks, the particles that make up protons and neutrons, the truly elementary particles? What are the three fundamental forces that physicists identify as holding particles together? Could they be manifestations of a single, universal force? A Teaching Legend On his own Middlebury College campus, Professor Wolfson is a teaching legend with an infectious enthusiasm for his subject and a knack for conveying difficult concepts in a way that fosters true understanding. He is the author of an introductory text on physics, a contributor to the esteemed publication Scientific American, and a specialist in interpreting science for the nonspecialist. In this course, Professor Wolfson uses extensive illustrations and diagrams to help bring to life the theories and concepts that he discusses. Thus we highly recommend our DVD version, although Professor Wolfson is mindful of our audio students and carefully describes visual materials throughout his lectures. Professor Richard Wolfson on the Second Edition of Einstein's Relativity: "The first version of this course was produced in 1995. In this new version, I have chosen to spend more time on the philosophical interpretation of quantum physics, and on recent experiments relevant to that interpretation. I have also added a final lecture on the theory of everything and its possible implementation through string theory. The graphic presentations for the DVD version have also been extensively revised and enhanced. But the goal remains the same: to present the key ideas of modern physics in a way that makes them clear to the interested layperson."

    Lobster rolls containing no lobster at all. Extra-virgin olive oil that isn’t. Fake foods are in our supermarkets, our restaurants, and our kitchen cabinets. Award-winning food journalist and travel writer Larry Olmsted exposes this pervasive and dangerous fraud perpetrated on unsuspecting Americans.     Real Food/Fake Food brings readers into the unregulated food industry, revealing that this shocking deception extends from high-end foods like olive oil, wine, and Kobe beef to everyday staples such as coffee, honey, juice, and cheese. It’s a massive bait and switch where counterfeiting is rampant and where the consumer ultimately pays the price. But Olmsted does more than show us what foods to avoid. A bona fide gourmand, he travels to the sources of the real stuff, to help us recognize what to look for, eat, and savor: genuine Parmigiano-Reggiano from Italy, fresh-caught grouper from Florida, authentic port from Portugal. Real foods that are grown, raised, produced, and prepared with care by masters of their craft.   Part cautionary tale, part culinary crusade, Real Food/Fake Food is addictively readable, mouth-wateringly enjoyable, and utterly relevant. Larry Olmsted convinces us why real food matters.

    Stamped from the Beginning uses the lives of five major American intellectuals to offer a window into the contentious debates between assimilationists and segregationists and between racists and anti-racists. From Puritan minister Cotton Mather to Thomas Jefferson, from fiery abolitionist William Lloyd Garrison to brilliant scholar W. E. B. Du Bois to legendary anti–prison activist Angela Davis, Kendi shows how and why some of our leading pro-slavery and pro–civil rights thinkers have challenged or helped cement racist ideas in America.As Kendi illustrates, racist thinking did not arise from ignorance or hatred. Racist ideas were created and popularized in an effort to defend deeply entrenched discriminatory policies and to rationalize the nation’s racial inequities in everything from wealth to health. While racist ideas are easily produced and easily consumed, they can also be discredited. In shedding much–needed light on the murky history of racist ideas, Stamped from the Beginning offers tools to expose them—and in the process, reason to hope.

    That day--chosen completely at random--turned out to be Sunday, December 28, 1986, by any conventional measure a most ordinary day. Weingarten spent the next six years proving that there is no such thing.That Sunday between Christmas and New Year's turned out to be filled with comedy, tragedy, implausible irony, cosmic comeuppances, kindness, cruelty, heroism, cowardice, genius, idiocy, prejudice, selflessness, coincidence, and startling moments of human connection, along with evocative foreshadowing of momentous events yet to come. Lives were lost. Lives were saved. Lives were altered in overwhelming ways. Many of these events never made it into the news; they were private dramas in the lives of private people. They were utterly compelling.One Day asks and answers the question of whether there is even such a thing as "ordinary" when we are talking about how we all lurch and stumble our way through the daily, daunting challenge of being human.

    That same year, a trove of Michael Jackson memorabilia—including his iconic crystal-encrusted white glove—was sold at auction for over $1 million to a guy who was, officially, just the lowly forestry minister of the tiny nation of Equatorial Guinea. And in 2014, Ukrainian revolutionaries raided the palace of their ousted president and found a zoo of peacocks, gilded toilets, and a floating restaurant modeled after a Spanish galleon. Unlikely as it might seem, there is a thread connecting these events, and Rachel Maddow follows it to its crooked source: the unimaginably lucrative and equally corrupting oil and gas industry. With her trademark black humor, Maddow takes us on a switchback journey around the globe, revealing the greed and incompetence of Big Oil and Gas along the way, and drawing a surprising conclusion about why the Russian government hacked the 2016 U.S. election. She deftly shows how Russia’s rich reserves of crude have, paradoxically, stunted its growth, forcing Putin to maintain his power by spreading Russia’s rot into its rivals, its neighbors, the West’s most important alliances, and the United States. Chevron, BP, and a host of other industry players get their star turn, most notably ExxonMobil and the deceptively well-behaved Rex Tillerson. The oil and gas industry has weakened democracies in developed and developing countries, fouled oceans and rivers, and propped up authoritarian thieves and killers. But being outraged at it is, according to Maddow, “like being indignant when a lion takes down and eats a gazelle. You can’t really blame the lion. It’s in her nature.” Blowout is a call to contain the lion: to stop subsidizing the wealthiest businesses on earth, to fight for transparency, and to check the influence of the world’s most destructive industry and its enablers. The stakes have never been higher. As Maddow writes, “Democracy either wins this one or disappears.”

    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.
