More than 2,500 years later, the issues they pondered continue to challenge, fascinate, and instruct us. Is reality stable and permanent or is it always changing? Are ethical values like justice and courage relative? Or are values "absolute"—simply and forever right and true? What is justice? What is happiness? How shall we best live our lives?An Introduction to Greek Philosophy beckons you to join this eternal discussion. For that is what this subject truly is: a conversation among thinkers that has continued through the centuries and remains accessible to us today. You find it constantly stimulating, sometimes controversial, and nearly always remarkably relevant.A Hunger for Reasons, not Myths or BeliefsProfessor David Roochnik has organized this series of 24 lectures as a "dialectical" approach (the word comes from the Greek dialegesthai: to converse). The philosophers are presented as if they were participating in a conversation. In this way, the course unfolds in a manner similar to the actual development of Greek philosophy.In this course, you study the development of Greek philosophy, meet its major thinkers, and explore the issues and ideas that concerned them. For example the first real philosophers were the Presocratics—literally, the philosophers who lived before Socrates. They included Thales of Miletus (585 B.C.E.–?), Anaximander (610–546), Anaximenes (approx. 550), Xenophanes (approx. 570) and Pythagoras (approx. 570–500).The Presocratics rejected myth and divine inspiration—such as had been embodied in the works of Homer and in Hesiod's creation story, the Theogony—as valid explanations of reality. Instead, they insisted that true understanding always requires a logos, a rational explanation (hence such English words as "psychology" and "biology").The Presocratics were concerned with issues such as identifying the arche or "Being": the thing that is the origin of all other things. They also introduced sophistic relativism, the notion that truth, goodness, and all other values were relative, depending entirely on the person or group that held them. This concept would become a major point of debate for the Greeks and for the ages.Are We Footnotes to Plato?The heroes of this course, and certainly of Greek philosophy, are Plato (429–347 B.C.E.) and his student, Aristotle (384–322 B.C.E.). Unlike the Presocratics, who wrote too little, Plato and Aristotle were prolific authors. Both argued against relativism and instead were staunch objectivists who believed that certain important values were absolutely and universally true. And both left a staggering mark on history.Alfred North Whitehead, the great 20th-century British philosopher, said, "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato." In the Middle Ages, Aristotle was held in such high esteem that he was simply known as "the philosopher."Among Plato's many contributions to philosophy is his ingenious device for the examination of ideas: his written dialogues. In them, Plato never uses his own voice. Instead, the dialogues take place among a changing cast of characters, and Socrates is the most notable among them. The effect is to invite us to take part in the conversation and, ultimately, to become philosophers.You study Plato's dialogues as well as his notion of the Forms. This was his response to relativism and proposed that every virtue and value has an absolute and perfect Form, which humans understand even before birth.Greek philosophy can be said to culminate with Aristotle, who wrote treatises on a breathtaking range of subjects. He is said to be the first to view knowledge as being divided into specific disciplines such as biology or astronomy. The university was later modeled on this approach. More than any other philosopher, Aristotle synthesized the views that preceded him.For Aristotle, one value was foremost and was contained in everything, from the tiniest organisms to the phenomena of fire to human beings: purpose. Everything has a purpose that can be recognized and objectively defined, and that gives meaning to life. You explore the details and rationale of Aristotle's teleological—or purposive—world-view, one of the most significant in history.An Invitation to ThinkIn this course, you not only learn about Greek philosophy but, to some extent, how to do it. Professor Roochnik emphasizes that Greek philosophy is ultimately not about facts or answers but about the give-and-take of ideas.By the end of these lectures, you will understand how Greek philosophy still heavily influences our view of life. We live today, Professor Roochnik maintains, at a time that is shaped by Presocratic, relativistic philosophy. Contemporary thinkers, and often the average person, have great difficulty finding objective truth or meaning in life.What have we lost in turning away from the world of Plato and Aristotle—a world where everything has a place and a purpose and life is saturated with value and meaning?On the other hand, what would we lose if we returned to that world?These are a few of the many questions that will give you ample food for thought. For the Greeks, that was the greatest feast of all.

    Three modern day Tom Sawyers, with no caving expertise but an abundance of bravado, made Hannibal ground zero for a terrifying calamity that would leave its traumatic mark for half a century. Joel Hoag, his brother Billy, and their friend Craig Dowell vanished after exploring a vast and complex maze cave system that had been exposed by highway construction. Fifty years later, their fate remains the ultimate unsolved mystery.

    And they did it without fanfare or recognition from their employer. Hiltzik's Dealers of Lightning provides a fascinating look at technohistory that sets the record straight. In Dealers of Lightning, Hiltzik describes the forces and faces behind the revolution that the Xerox PARC team single-handedly spawned. The Xerox PARC group was composed solely of top technical minds. The decision was made at Xerox headquarters to give the team complete freedom from deadlines and directives, in hopes of fostering a true creative environment. It worked — perhaps too well. The team responded with a steady output of amazing technology, including the first version of the Internet, the first personal computer, user-friendly word-processing programs, and pop-up menus. Xerox, far from ready for the explosion of innovation, failed to utilize the technology dreamed up by the group. Out of all the dazzling inventions born at Xerox PARC, only a handful were developed and marketed by Xerox. However, one of these inventions, the laser printer, proved successful enough to earn billions for the company, therefore justifying its investment in the research center. Most oftheteam's creations would go on to be developed and perfected by other companies, such as IBM, Apple, and Microsoft. Drawing from interviews with the engineers, executives, and scientists involved in the Xerox PARC, Dealers of Lightning chronicles an amazing era of egos, ideas, and inventions at the dawn of the computer age.

    From the transistor to the laser, it s hard to find an aspect of modern life that hasn t been touched by Bell Labs. Why did so many transformative ideas come from Bell Labs? In "The Idea Factory," Jon Gertner traces the origins of some of the twentieth century s most important inventions and delivers a riveting and heretofore untold chapter of American history. At its heart this is a story about the life and work of a small group of brilliant and eccentric men Mervin Kelly, Bill Shockley, Claude Shannon, John Pierce, and Bill Baker who spent their careers at Bell Labs. Their job was to research and develop the future of communications. Small-town boys, childhood hobbyists, oddballs: they give the lie to the idea that Bell Labs was a grim cathedral of top-down command and control.Gertner brings to life the powerful alchemy of the forces at work behind Bell Labs inventions, teasing out the intersections between science, business, and society. He distills the lessons that abide: how to recruit and nurture young talent; how to organize and lead fractious employees; how to find solutions to the most stubbornly vexing problems; how to transform a scientific discovery into a marketable product, then make it even better, cheaper, or both. Today, when the drive to invent has become a mantra, Bell Labs offers us a way to enrich our understanding of the challenges and solutions to technological innovation. Here, after all, was where the foundational ideas on the management of innovation were born. "The Idea Factory" is the story of the origins of modern communications and the beginnings of the information age a deeply human story of extraordinary men who were given extraordinary means time, space, funds, and access to one another and edged the world into a new dimension."

    The title of his most famous work, Ab Urbe Condita ("From the Founding of the City"), expresses the scope and magnitude of Livy's undertaking. He wrote in a mixture of annual chronology and narrative. Livy claims that lack of historical data prior to the sacking of Rome in 387 BC by the Gauls made his task more difficult. He wrote the majority of his works during the reign of Augustus. However, he is often identified with an attachment to the Roman Republic and a desire for its restoration. His writing style was poetic and archaic in contrast to Caesar's and Cicero's styles. Also, he often wrote from the Romans' opponent's point of view in order to accent the Romans' virtues in their conquest of Italy and the Mediterranean.

    Auden. What does Roman Britain mean to us now? How were its physical remains rediscovered and made sense of? How has it been reimagined, in story and song and verse?Charlotte Higgins has traced these tales by setting out to discover the remains of Roman Britain for herself, sometimes on foot, sometimes in a splendid, though not particularly reliable, VW camper van. Via accounts of some of Britain's most intriguing, and often unjustly overlooked ancient monuments, Under Another Sky invites us to see the British landscape, and British history, in an entirely fresh way: as indelibly marked by how the Romans first imagined, and wrote, these strange and exotic islands, perched on the edge of the known world, into existence.

    

    The answer to this age-old riddle is universally relevant to our lives. The implications of our views on it can affect everything from small choices we make every day to our perspective on criminal justice and capital punishment. From the Stoics to Boethius, from Kant to Hume, from Sartre to contemporary philosophers, great minds have puzzled over this debate for centuries.Now you can learn the intriguing details of this fundamental philosophical question with Great Philosophical Debates: Free Will and Determinism, 24 fascinating lectures by Shaun Nichols, award-winning Professor of Philosophy and Cognitive Science at the University of Arizona."The Great Courses.com

    The Americans were outsiders to the sport, the underdogs of the event, a 500-to-1 long shot. But they were also proud and loyal men -- to one another, to their communities, and certainly to their country. Facing almost no time to prepare, opponents with superior training, and skepticism from the rest of the world, this ragtag group of unknowns was inspired to a stunning victory over England and one of the most thrilling upsets in the history of sports.Written by critically acclaimed author Geoffrey Douglas, and now a film directed by David Anspaugh (Hoosiers), The Game of Their Lives takes us back to a time before million-dollar contracts and commercial endorsements, and introduces us to the athletes -- the Americans -- who showed the world just how far a long shot could really go.

    The massive effort to design and build it in a seemingly impossible timeframe is still hailed as one of the most herculean efforts and well-kept secrets in the history of the Indy 500. In the new book, Beast, bestselling author Jade Gurss chronicles the subterfuge and debunks the myths about this legendary engine that persist twenty years on. Gurss interviewed key players involved in the race to undercover the story of how this engine powered the Penske PC23 chassis to one of the most talked-about Indy 500 races in history. The British race-engine experts at Ilmor Engineering offer detail about the design and manufacture of the engine. Roger Penske’s team reveals how the engine and car were tested and developed, and how Mercedes came to be involved in the project. The story unfolds as Roger Penske and Mario Illien and Paul Morgan of Ilmor play every card they possess to create an incredible race engine--even rare World War II fighter planes and supersonic jets roar into the heart of this high-tech tale. Drivers Al Unser Jr., Emerson Fittipaldi, and Paul Tracy provide details on the tense weeks leading up race day. The book reaches a suspenseful climax at 240 miles per hour at the Indy 500 noone can forget. Wrapped up in the drama and intrigue are real business and motivational lessons which made Roger Penske one of the most successful businessmen in the world and that helped Ilmor and its cofounders, Mario Illien and the late Paul Morgan, design and manufacture Indy car and Formula 1 championship–winning engines. Beast is not only a must-read for sports and race fans, but a compelling narrative for those who enjoy genuine lessons in business and technology or thrilling mysteries based on actual events.

    The view 16-year-old Thomas Osborne first had of Muskoka was at night, trudging alone with his even younger brother along unmarked primitive roads to find their luckless father who, in 1875, had decided to make a new start for his beleaguered family on some "free land" in the bush east of the pioneer village of Huntsville, Ontario. The miracle is that Thomas lived to tell the tale.For the next five years Thomas endured starvation, falling through the ice and freezing, accidents with axes and boats, and narrow escapes from wolves and bears. Many years later, after returning to the United States, Osborne wrote down all his adventures in a graphic memoir that has become, in the words of author and journalist Roy MacGregor, "an undiscovered Canadian classic."Reluctant Pioneer provides a brooding sense of adventure and un- sentimental realism to deliver a powerful account of pioneer life where tragedies arrive as naturally as rain and where humour resides in irony.
