Now - with the technological advances of modern archaeology and a new perspective on world history - we are finally able to piece together their compelling true stories. In Ancient Civilizations of North America, Professor Edwin Barnhart, Director of the Maya Exploration Center, will open your eyes to a fascinating world you never knew existed - even though you've been living right next to it, or even on top of it, for as long as you've been on the continent.The peoples of ancient North America were exceptionally knowledgeable about their environment, but their intellectual and artistic curiosity went much beyond the immediate need for food and safety. Beginning thousands of years ago, and without benefit of written language, native peoples became mathematicians, construction and soil engineers, astronomers, urban planners, and more. They developed thriving cities, extensive trade routes, canals to bring water to the desert, and earthworks we still marvel over today.In 24 exciting lectures, you'll learn about the vibrant cities of Poverty Point, the first city in North America, built about 3,500 years ago, and Cahokia, the largest city of ancient North America. You'll explore the many ways in which the Chacoan environment provided cultural and religious focus for peoples of the southwest. And you'll learn about the Iroquoian source of some of our most basic "American" values.

    Irina isn’t rich, not quite, but she does have an artificial memory that gives her perfect recall and lets her act as a medium between her various employers and their AIs, which are complex to the point of opacity. It’s a good gig, paying enough for the annual visits to the Mayo Clinic that keep her from aging.Kern has no such access; he’s one of the many refugees in the sprawling drone-built favelas on the city’s periphery, where he lives like a monk, training relentlessly in martial arts, scraping by as a thief and an enforcer. Thales is from a different world entirely—the mathematically inclined scion of a Brazilian political clan, he’s fled to L.A. after the attack that left him crippled and his father dead.A ragged stranger accosts Thales and demands to know how much he can remember. Kern flees for his life after robbing the wrong mark. Irina finds a secret in the reflection of a laptop’s screen in her employer’s eyeglasses. None are safe as they’re pushed together by subtle forces that stay just out of sight.Vivid, tumultuous, and propulsive, Void Star is Zachary Mason’s mind-bending follow-up to his bestselling debut, The Lost Books of the Odyssey.

    Tom, a contemporary historian, and his theoretical physicist girlfriend Sharon, become interested. Tom indeed becomes obsessed. By all logic, the town should have survived, but it didn't and that violates everything Tom knows about history. What's was special about Eifelheim that it utterly disappeared more than 600 years ago? Father Dietrich is the village priest of Oberhochwald, the village that will soon gain the name of Teufelheim, in later years corrupted to Eifelheim, in the year 1348, when the Black Death is gathering strength across Europe but is still not nearby. Dietrich is an educated man, knows science and philosophy, and to his astonishment becomes the first contact between humanity and an alien race from a distant star when their interstellar ship crashes in the nearby forest. It is a time of wonders, in the shadow of the plague.Tom and Sharon, and Father Dietrich, have a strange and intertwined destiny of tragedy and triumph in this brilliant SF novel by the winner of the Robert A. Heinlein Award.

    The world that he remembers was much as we know it today. Now, as he regains his faculties through a cure developed during the years of his near-fatal decline, he discovers that the world has changed and so has his place in it. He was a world-renowned poet. Now he is seventy-five years old, though by a medical miracle he looks much younger, and he’s starting over, for the first time unsure of his poetic gifts. Living with his son’s family, he has no choice but to learn how to cope with a new information age in which the virtual and the real are a seamless continuum, layers of reality built on digital views seen by a single person or millions, depending on your choice. But the consensus reality of the digital world is available only if, like his thirteen-year-old granddaughter Miri, you know how to wear your wireless access—through nodes designed into smart clothes—and to see the digital context—through smart contact lenses. With knowledge comes risk. When Robert begins to re-train at Fairmont High, learning with other older people what is second nature to Miri and other teens at school, he unwittingly becomes part of a wide-ranging conspiracy to use technology as a tool for world domination. In a world where every computer chip has Homeland Security built-in, this conspiracy is something that baffles even the most sophisticated security analysts, including Robert’s son and daughter-in law, two top people in the U.S. military. And even Miri, in her attempts to protect her grandfather, may be entangled in the plot. As Robert becomes more deeply involved in conspiracy, he is shocked to learn of a radical change planned for the UCSD Geisel Library; all the books there, and worldwide, would cease to physically exist. He and his fellow re-trainees feel compelled to join protests against the change. With forces around the world converging on San Diego, both the conspiracy and the protest climax in a spectacular moment as unique and satisfying as it is unexpected.

    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."

    He found a precarious balance as a con man, but when a client offers him untold wealth to move a squadron of warships across an enemy wormhole, he must embrace his birthright to even try. In fact, the job is so big that he'll need a crew built from all the new sub-branches of humanity. If he succeeds, he might trigger an interstellar war, but success might also point the way to the next step of Homo quantus evolution.

    And it was to be the most violent Summertide ever, due to the Grand Conjunction of the system's stars and planets, something that happened only every 350,000 years.Access to the unstable Quake was supposed to be prohibited, but some very insistent travelers were determined to make the trip. Professor Darya Lang, who had made a career studying artifacts left by the long-vanished aliens called the Builders, had a hunch that during this unusual Summertide she might find the Builders themselves. Louis Nenda and the Cecropian Atvar H'sial had their own interests in Quake, and would do anything to get there. And Councilor Julius Graves was hunting murderers—if they were hiding on Quake, he needed no one's permission to search for them.Planetary Administrators Hans Rebka and Max Perry had no choice but to go to Quake themselves—risking their lives to protect the others—and to learn, just maybe, the secret of Summertide and the Builders...
