    Many of the documents emphasize America’s uniqueness and contributions to the world, but they also present different views on some of the major issues and disputes in American history and government, especially on the meaning of liberty, the injustice of slavery, and the demands of progress. Taken as such, the documents reveal a kind of political dialogue to readers, an ongoing and profoundly consequential conversation about how Americans have agreed and often disagreed on the meaning of freedom and self-government. 50 Core American Documents invites teachers and citizens alike to join in this American political dialogue.The Ashbrook Center restores and strengthens the capacities of the American people for constitutional self-government. The Center teaches students and teachers across our country why America is exceptional and what America represents in the long history of the world.

    For something as elemental as counting and estimating the world around us, it seems like a confusing tool to use. So how did we end up with it?Most of the rest of the world is on the metric system, and for a time in the 1970s America appeared ready to make the switch. Yet it never happened, and the reasons for that get to the root of who we think we are, just as the measurements are woven into the ways we think. John Marciano chronicles the origins of measurement systems, the kaleidoscopic array of standards throughout Europe and the thirteen American colonies, the combination of intellect and circumstance that resulted in the metric system’s creation in France in the wake of the French Revolution, and America’s stubborn adherence to the hybrid United States Customary System ever since. As much as it is a tale of quarters and tenths, it is a human drama, replete with great inventors, visionary presidents, obsessive activists, and science-loving technocrats.Anyone who reads this inquisitive, engaging story will never read Robert Frost’s line “miles to go before I sleep” or eat a foot-long sub again without wondering, Whatever happened to the metric system?

    When famed archaeologist Arthur Evans unearthed the ruins of a sophisticated Bronze Age civilization that flowered on Crete 1,000 years before Greece's Classical Age, he discovered a cache of ancient tablets, Europe's earliest written records. For half a century, the meaning of the inscriptions, and even the language in which they were written, would remain a mystery. Award-winning New York Times journalist Margalit Fox's riveting real-life intellectual detective story travels from the Bronze Age Aegean--the era of Odysseus, Agamemnon, and Helen--to the turn of the 20th century and the work of charismatic English archeologist Arthur Evans, to the colorful personal stories of the decipherers. These include Michael Ventris, the brilliant amateur who deciphered the script but met with a sudden, mysterious death that may have been a direct consequence of the decipherment; and Alice Kober, the unsung heroine of the story whose painstaking work allowed Ventris to crack the code.

    It is the single greatest event in all human history. Discover the fascinating origin of Rome and its mysterious Etruscan connections, its first faltering steps toward republican government, and its methodical subjugation of surrounding tribes. Slowly, the puritanical Roman Republic asserts control over all of Italy and in the process forges a political unity which proves enduring. That unity is sorely tested as Rome comes into conflict with Carthage and Hannibal, a horrifying ordeal which alters world history for all time. A resurgent Rome is next drawn into the intrigues of the eastern Mediterranean, finally conquering the Greek speaking world...only to end up surrendering itself to a seductive, decadent Hellenistic culture. A century of politcal tension and civil strife ensues. Follow the rise of powerful men like the brothers Tiberius and Caius Gracchus, Marius, Sulla, Pompey, Cicero and the greatest Roman of them all - Julius Caesar. With Caesar's assassination comes renewed civil war. The aristocratic senatorial faction is defeated and the Republican form of government is replaced by dictatorship. Caesar's adopted nephew, Augustus, comes to power as the first Roman Emperor and puts into place the most extraordinary experiment in imperial government ever attempted. In the process, he paves the way for a long period of peace, a golden age, the likes of which has never before been seen. The Empire is ruled by one dynasty after another - some good, some bad - until it reaches its apogee during the age of the brilliant Antonine emperors. But chaos follows with a series of corrupt rulers, and only the strong leadership of Diocletion 85 years later brings stability. Shortly afterward, Constantine's rule promotes the new faith of Christianity and makes it the official religion of the empire. But the downward spiral of decay cannot be reversed. Economic disruptions, plague and barbarian invasions prove too much for Rome, and the western half of the empire descends into a maelstrom of ignorance, dispair and random violence from which it will not emerge for many centuries.

    He was the most influential member of the aristocratic Tolstoy family. His first publications were three autobiographical novels, Childhood, Boyhood, and Youth (1852-1856). They tell of a rich landowner's son and his slow realization of the differences between him and his peasants. As a fiction writer Tolstoy is widely regarded as one of the greatest of all novelists, particularly noted for his masterpieces War and Peace (1869) and Anna Karenina (1877). In their scope, breadth and realistic depiction of 19th-century Russian life, the two books stand at the peak of realist fiction. As a moral philosopher Tolstoy was notable for his ideas on nonviolent resistance through works such as The Kingdom of God is Within You (1894). During his life, Tolstoy came to the conclusion that William Shakespeare is a bad dramatist and not a true artist at all. Tolstoy explained his views in a critical essay on Shakespeare written in 1903.

    Stringer's new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies.Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved.Lone Survivors will be the definitive account of who and what we were, and will change perceptions about our origins and about what it means to be human.
