    But who were the early speakers of this ancient mother tongue, and how did they manage to spread it around the globe? Until now their identity has remained a tantalizing mystery to linguists, archaeologists, and even Nazis seeking the roots of the Aryan race. The Horse, the Wheel, and Language lifts the veil that has long shrouded these original Indo-European speakers, and reveals how their domestication of horses and use of the wheel spread language and transformed civilization.Linking prehistoric archaeological remains with the development of language, David Anthony identifies the prehistoric peoples of central Eurasia's steppe grasslands as the original speakers of Proto-Indo-European, and shows how their innovative use of the ox wagon, horseback riding, and the warrior's chariot turned the Eurasian steppes into a thriving transcontinental corridor of communication, commerce, and cultural exchange. He explains how they spread their traditions and gave rise to important advances in copper mining, warfare, and patron-client political institutions, thereby ushering in an era of vibrant social change. Anthony also describes his fascinating discovery of how the wear from bits on ancient horse teeth reveals the origins of horseback riding.The Horse, the Wheel, and Language solves a puzzle that has vexed scholars for two centuries--the source of the Indo-European languages and English--and recovers a magnificent and influential civilization from the past.

    A few years ago, Mark Adams made a strange discovery: Everything we know about the lost city of Atlantis comes from the work of one man, the Greek philosopher Plato. Then he made a second, stranger discovery: Amateur explorers are still actively searching for this sunken city all around the world, based entirely on the clues Plato left behind. Exposed to the Atlantis obsession, Adams decides to track down these people and determine why they believe it’s possible to find the world’s most famous lost city and whether any of their theories could prove or disprove its existence. He visits scientists who use cutting-edge technology to find legendary civilizations once thought to be fictional. He examines the numerical and musical codes hidden in Plato’s writings, and with the help of some charismatic sleuths traces their roots back to Pythagoras, the sixth-century BC mathematician. He learns how ancient societies transmitted accounts of cataclysmic events—and how one might dig out the “kernel of truth” in Plato’s original tale.Meet Me in Atlantis is Adams’s enthralling account of his quest to solve one of history’s greatest mysteries; a travelogue that takes readers to fascinating locations to meet irresistible characters; and a deep, often humorous look at the human longing to rediscover a lost world.

    It was the marvel of its age?legendary for its vast palaces, safe harbors, and magnificent lighthouse. But it was most famous for the astonishing intellectual fluorescence it fostered and the library it produced. If the European Renaissance was the ?rebirth? of Western culture, then Alexandria, Egypt, was its birthplace. It was here mankind first discovered that the earth was not flat, originated atomic theory, invented geometry, systematized grammar, translated the Old Testament into Greek, built the steam engine, and passed their discoveries on to future generations via the written word. Julius Caesar, Anthony and Cleopatra, Jewish scholars, Greek philosophers, and devout early Christians all play a part in the rise and fall of the city that stood ?at the conjunction of the whole world.? Compulsively readable and sparkling with fresh insights into science, philosophy, culture, and invention, this is an irresistible, eye-opening delight.

    The great heritage of western civilization - from the Greek and Roman classics to Jewish and Christian works - would have been utterly lost were it not for the holy men and women of unconquered Ireland. In this delightful and illuminating look into a crucial but little-known "hinge" of history, Thomas Cahill takes us to the "island of saints and scholars, " the Ireland of St. Patrick and the Book of Kells. Here, far from the barbarian despoliation of the continent, monks and scribes laboriously, lovingly, even playfully preserved the west's written treasures. With the return of stability in Europe, these Irish scholars were instrumental in spreading learning. Thus the Irish not only were conservators of civilization, but became shapers of the medieval mind, putting their unique stamp on western culture.

    Clear Science Teaching to Set the Stage for an Awe-Inspiring Course Created for a lay audience and readily accessible, in this course science always takes precedence over drama. The lectures are certainly entertaining, often funny, even awe-inspiring at times, as befits the subject matter. Even though you will be entertained, you will be learning good science. Clear introductions to essential principles of physics support these lectures, including density, quantum theory, gravity, and the General Theory of Relativity. Professor Neil deGrasse Tyson also includes forays into disciplines such as chemistry and biology as needed to explain events in astronomy. For example, Dr. Tyson begins one lecture at a point 13 billion years ago, when all space, matter, and energy in the known universe were contained in a volume less than one-trillionth the size of a pinpoint-about the size of a single atom. By the time he finishes, the cosmos has been stretched, the planets and our Earth formed, and 70 percent of existing Earth species have been wiped out by a gigantic asteroidclearing the way for the evolution of humanity. Along the way he has touched on Einstein's famous equation, E=mc2; on the four forces that were once unified in the early cosmos in a way physicists are still trying to explain; and on the chemical enrichment of the universe by exploding supernovae, which give the universe its necessary supply of heavier elements including oxygen, nitrogen, iron and, most important, carbon. Carbon, we learn, is a "sticky" atom, capable of making more kinds of molecules than all other elements combined. It's the ideal element with which to experiment in the building of life forms and is, of course, the element responsible for the remarkable diversity of life, including us. As Dr. Tyson notes, we are made of stardust, just as the planets are. And he has created a course that explains exactly how that came to be, beginning with a grounding in the basic "machinery" of matter, forces, and energy that has been discovered on Earth and which also reveals itself throughout the universe. The Stark and Violent Beauty of the Universe With this basic foundation in place, explanations of cosmic events fall logically into place, and the realities of the universe-including its eventual demise-are revealed in stark and often violent beauty. You learn: how Saturn's rings were formed, and why they will eventually be lost why low-density conditions are necessary to produce the drama of the northern and southern auroras why even the most jagged and wild of the Earth's mountain ranges are, from a cosmic standpoint, really part of a perfectly smooth sphere how black holes are formed and the extraordinary way in which they can wreak havoc in the universe how asteroids moving through space represent threats of extraordinary consequence to Earth, no matter how long those threats may take to be realized why the seemingly infinite panorama of celestial bodies revealed by the Hubble Space Telescope's famous "Deep Field" so intrigued astronomers how astronomers actually look for new planets, why the odds seem overwhelmingly in favor of some kind of life out there, whether we ever make contact or not. Most important, none of these ideas are presented as isolated "space factoids" that serve no purpose but to entertain. They are there to illustrate and reinforce the key principles of physics and astrophysics that are continually being presented in this course. But the inclusion of real science doesn't prevent Dr. Tyson from having some fun, either. When it's time to show how a black hole might remove one from the universe, he leads you right up to the "event horizon" and slips you in-feet first. Since the event horizon represents the point within which nothing, not even light, can escape, you might think this is a bad idea. And you would be right. But as you plummet toward the "singularity" at the heart of the black hole, you will learn firsthand about the interesting effects of gravity truly unleashed, including what physicists refer to, with a straight face, as "spaghettification." (Actually, Professor Tyson recommends that you be sucked in to a large black hole rather than a small one. You'll still be spaghettified, but it won't happen as quickly.) But make no mistake: Dr. Tyson does not consider the cosmos a laughing matter, this kind of whimsical touch notwithstanding. In spite of his training, he remains, admittedly, still in awe of his subject. And he has created a course that might well produce the same feeling in you.

    And of a nation that fought a Civil War that freed its slaves, and outlawed segregation and discrimination.This is history shaped by Revolutionary War and Vietnam, Thomas Jefferson and William Jefferson Clinton, Puritanism and Feminism, Booker T. Washington and Martin Luther King, Jamestown and Disneyland, Harpers Ferry and Henry Ford, oil wells and Orson Welles.This is a review of the extraordinary blend of people, ideas, inventions, and events that comprise The History of the United States. In this seven-part, 84-lecture series, three noted historians and lecturers—two of whom teach other popular Teaching Company courses—present the nation's past through their areas of special interest.

    After its founding in 509 BCE, Rome grew from an unremarkable Italian city-state to the dominant superpower of the Mediterranean world. Through it all, the Romans never allowed a single man to seize control of the state. Every year for four hundred years the annually elected consuls voluntarily handed power to their successors. Not once did a consul give in to the temptation to grab absolute power and refuse to let it go. It was a run of political self-denial unmatched in the history of the world. The disciplined Roman republicans then proceeded to explode out of Italy and conquer a world filled with petty tyrants, barbarian chieftains, and despotic kings.But the very success of the Republic proved to be its undoing. The republican system was unable to cope with the vast empire Rome ruled. Bankrolled by mountains of imperial wealth and without a foreign enemy to keep them united, ambitious Roman leaders began to stray from the republican austerity of their ancestors. Almost as soon as they had conquered the Mediterranean, Rome would become engulfed in violent political conflicts and civil wars that would destroy the Republic less than a century later.The Storm Before the Storm tells the story of the beginning of the end of the Roman Republic--the story of the first generation that had to cope with the dangerous new political environment made possible by Rome's unrivaled domination over the known world. The tumultuous years from 133-80 BCE set the stage for the fall of the Republic.The Republic faced issues like rising economic inequality, increasing political polarization, the privatization of the military, endemic social and ethnic prejudice, rampant corruption, ongoing military quagmires, and the ruthless ambition and unwillingness of elites to do anything to reform the system in time to save it--a situation that draws many parallels to present-day America. These issues are among the reasons why the Roman Republic would fall. And as we all know, those who do not learn from history are doomed to repeat it.

    By the end of the fifth century, Roman rule had vanished in western Europe and much of northern Africa, and only a shrunken Eastern Empire remained. In his account of the fall of the Roman Empire, prizewinning author Adrian Goldsworthy examines the painful centuries of the superpower’s decline. Bringing history to life through the stories of the men, women, heroes, and villains involved, the author uncovers surprising lessons about the rise and fall of great nations.This was a period of remarkable personalities, from the philosopher-emperor Marcus Aurelius to emperors like Diocletian, who portrayed themselves as tough, even brutal, soldiers. It was a time of revolutionary ideas, especially in religion, as Christianity went from persecuted sect to the religion of state and emperors. Goldsworthy pays particular attention to the willingness of Roman soldiers to fight and kill each other. Ultimately, this is the story of how an empire without a serious rival rotted from within, its rulers and institutions putting short-term ambition and personal survival over the wider good of the state.

    Amazingly, he completed the task in an intense six weeks, and Eine kurze Weltgeschichte für junge Leser was published in Vienna to immediate success, and is now available in seventeen languages across the world. Toward the end of his long life, Gombrich embarked upon a revision and, at last, an English translation. A Little History of the World presents his lively and involving history to English-language readers for the first time. Superbly designed and freshly illustrated, this is a book to be savored and collected. In forty concise chapters, Gombrich tells the story of man from the stone age to the atomic bomb. In between emerges a colorful picture of wars and conquests, grand works of art, and the spread and limitations of science. This is a text dominated not by dates and facts, but by the sweep of mankind's experience across the centuries, a guide to humanity's achievements and an acute witness to its frailties. The product of a generous and humane sensibility, this timeless account makes intelligible the full span of human history.

    In Battling the Gods, Tim Whitmarsh journeys into the ancient Mediterranean, a world almost unimaginably different from our own, to recover the stories and voices of those who first refused the divinities.Homer’s epic poems of human striving, journeying, and passion were ancient Greece’s only “sacred texts,” but no ancient Greek thought twice about questioning or mocking his stories of the gods. Priests were functionaries rather than sources of moral or cosmological wisdom. The absence of centralized religious authority made for an extraordinary variety of perspectives on sacred matters, from the devotional to the atheos, or “godless.” Whitmarsh explores this kaleidoscopic range of ideas about the gods, focusing on the colorful individuals who challenged their existence. Among these were some of the greatest ancient poets and philosophers and writers, as well as the less well known: Diagoras of Melos, perhaps the first self-professed atheist; Democritus, the first materialist; Socrates, executed for rejecting the gods of the Athenian state; Epicurus and his followers, who thought gods could not intervene in human affairs; the brilliantly mischievous satirist Lucian of Samosata.Before the revolutions of late antiquity, which saw the scriptural religions of Christianity and Islam enforced by imperial might, there were few constraints on belief. Everything changed, however, in the millennium between the appearance of the Homeric poems and Christianity’s establishment as Rome’s state religion in the fourth century AD. As successive Greco-Roman empires grew in size and complexity, and power was increasingly concentrated in central capitals, states sought to impose collective religious adherence, first to cults devoted to individual rulers, and ultimately to monotheism. In this new world, there was no room for outright disbelief: the label “atheist” was used now to demonize anyone who merely disagreed with the orthodoxy—and so it would remain for centuries.As the twenty-first century shapes up into a time of mass information, but also, paradoxically, of collective amnesia concerning the tangled histories of religions, Whitmarsh provides a bracing antidote to our assumptions about the roots of freethinking. By shining a light on atheism’s first thousand years, Battling the Gods offers a timely reminder that nonbelief has a wealth of tradition of its own, and, indeed, its own heroes. From the Hardcover edition.

    

    (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.

This edition has been updated with new suggested readings and illustrations. "[A] highly accessible, and comprehensive history of Greece and its civilization from prehistory through the collapse of Alexander the Great's empire. ...A highly readable account of ancient Greece, particularly useful as an introductory or review text for the student of the general reader." --Kirkus Reviews "Photographs and maps enhance this solid first lesson about the ancients." --Booklist

    The Lost History of Christianity unveils a vast and forgotten network of the world's largest and most influential Christian churches that existed to the east of the Roman Empire. These churches and their leaders ruled the Middle East for centuries and became the chief administrators and academics in the new Muslim empire. The author recounts the shocking history of how these churches—those that had the closest link to Jesus and the early church—died.Jenkins takes a stand against current scholars who assert that variant, alternative Christianities disappeared in the fourth and fifth centuries on the heels of a newly formed hierarchy under Constantine, intent on crushing unorthodox views. In reality, Jenkins says, the largest churches in the world were the “heretics” who lost the orthodoxy battles. These so-called heretics were in fact the most influential Christian groups throughout Asia, and their influence lasted an additional one thousand years beyond their supposed demise.Jenkins offers a new lens through which to view our world today, including the current conflicts in the Middle East, Asia, and Africa. Without this lost history, we lack an important element for understanding our collective religious past. By understanding the forgotten catastrophe that befell Christianity, we can appreciate the surprising new births that are occurring in our own time, once again making Christianity a true world religion.
