    As a result, whether we realize it or not, the drive to obtain food has been a major catalyst across all of history, from prehistoric times to the present. Epicure Jean-Anthelme Brillat-Savarin said it best: "Gastronomy governs the whole life of man." In fact, civilization itself began in the quest for food. Humanity's transition to agriculture was not only the greatest social revolution in history, but it directly produced the structures and institutions we call "civilization." In 36 fascinating lectures, award-winning Professor Albala puts this extraordinary subject on the table, taking you on an enthralling journey into the human relationship to food. With this innovative course, you'll travel the world discovering fascinating food lore and culture of all regions and eras - as an eye-opening lesson in history as well as a unique window on what we eat today.

    That book was the last surviving manuscript of an ancient Roman philosophical epic, On the Nature of Things, by Lucretius—a beautiful poem of the most dangerous ideas: that the universe functioned without the aid of gods, that religious fear was damaging to human life, and that matter was made up of very small particles in eternal motion, colliding and swerving in new directions.The copying and translation of this ancient book—the greatest discovery of the greatest book-hunter of his age—fueled the Renaissance, inspiring artists such as Botticelli and thinkers such as Giordano Bruno; shaped the thought of Galileo and Freud, Darwin and Einstein; and had a revolutionary influence on writers such as Montaigne and Shakespeare and even Thomas Jefferson.

    Frederick Starr tells the fascinating but largely unknown story of Central Asia's medieval enlightenment through the eventful lives and astonishing accomplishments of its greatest minds--remarkable figures who built a bridge to the modern world. Because nearly all of these figures wrote in Arabic, they were long assumed to have been Arabs. In fact, they were from Central Asia--drawn from the Persianate and Turkic peoples of a region that today extends from Kazakhstan southward through Afghanistan, and from the easternmost province of Iran through Xinjiang, China.Lost Enlightenment recounts how, between the years 800 and 1200, Central Asia led the world in trade and economic development, the size and sophistication of its cities, the refinement of its arts, and, above all, in the advancement of knowledge in many fields. Central Asians achieved signal breakthroughs in astronomy, mathematics, geology, medicine, chemistry, music, social science, philosophy, and theology, among other subjects. They gave algebra its name, calculated the earth's diameter with unprecedented precision, wrote the books that later defined European medicine, and penned some of the world's greatest poetry. One scholar, working in Afghanistan, even predicted the existence of North and South America--five centuries before Columbus. Rarely in history has a more impressive group of polymaths appeared at one place and time. No wonder that their writings influenced European culture from the time of St. Thomas Aquinas down to the scientific revolution, and had a similarly deep impact in India and much of Asia.Lost Enlightenment chronicles this forgotten age of achievement, seeks to explain its rise, and explores the competing theories about the cause of its eventual demise. Informed by the latest scholarship yet written in a lively and accessible style, this is a book that will surprise general readers and specialists alike.

    They could not have been more different, and they would meet only for a short time in 1502, but the events that transpired when they did would significantly alter each man’s perceptions and the course of Western history.In 1502, Italy was riven by conflict, with the city of Florence as the ultimate prize. Machiavelli, the consummate political manipulator, attempted to placate the savage Borgia by volunteering Leonardo to be Borgia’s chief military engineer. That autumn, the three men embarked together on a brief, perilous, and fateful journey through the mountains, remote villages, and hill towns of the Italian Romagna the details of which were revealed in Machiavelli’s frequent dispatches and Leonardo’s meticulous notebooks. Superbly written and thoroughly researched, The Artist, the Philosopher, and the Warrioris a work of narrative genius whose subject is the nature of genius itself.

    That was indeed what life was like in the earliest settlements, but by 5,000 years ago, life in some places had become much more sophisticated than we might think. Impressive achievements - like stepped temples that towered like mountains, elaborate palaces (some with bathrooms and plumbing), and complex houses - were also a part of life for people who lived in cities that arose thousands of years ago, particularly in the fertile region that emerged along the Tigris and Euphrates Rivers.Welcome to Mesopotamia, the ancient name for the region that is now Iraq, a remarkably advanced civilization that flourished for two-thirds of the time that civilization has existed on Earth. Mesopotamians mastered irrigation agriculture; built the first complex urban societies; developed writing, literature, and law; and united vast regions through warfare and diplomacy. While civilizations like Greece and Rome have an unbroken tradition of written histories, the rich history of Mesopotamia has only been recently rediscovered, thanks to the decipherment of Mesopotamia's cuneiform writing less than 200 years ago. In this 24-lecture course taught by Professor Podany, you'll fill in the blanks of your historical understanding as you witness a whole new world opening before your eyes.Riveting stories about kings and priestesses as well as ordinary people from all walks of life transport you back in time, giving you invaluable insights into the history of a landmark region that has long been known as the cradle of civilization.

    Epic in scope and set against the beautifully rendered backdrop of Renaissance Italy, The Borgias is a thrilling new depiction of these celebrated personalities and an era unsurpassed in beauty, terror, and intrigue.

    From the rising and setting of the sun to the cycles of nature, the thought processes in our brains, and the biorhythms in our day, nothing so pervades our existence and yet is so difficult to explain. Time seems to be woven into the very fabric of the universe. But why? Consider these contrasting views of time: A movie of a person diving into a pool has an obvious arrow of time. When the movie is played backward, everyone recognizes that it shows an event that would never occur in the real world. But zoom in on any part of this scene at the atomic scale and the movie can be run backward or forward and be indistinguishable. Either way, the particle interactions are consistent with the laws of physics. Why does one movie have an arrow of time moving in only one direction and the other does not? Surprisingly, the search for an answer leads through some of the most pioneering fields of physics, including thermodynamics, relativity, quantum theory, and cosmology. The key concept is called "entropy," which is related to the second law of thermodynamics, considered by many scientists to be the most secure law in all of physics. But that's only the beginning, since the quest for the ultimate theory of time draws on such exciting ideas as black holes, cosmic inflation, and dark energy, before closing in on a momentous question that until recently was considered unanswerable: What happened before the big bang? In 24 riveting half-hour lectures, Mysteries of Modern Physics: Time takes you on a mind-expanding journey through the past, present, and future, guided by Professor Sean Carroll, noted author and Senior Research Associate in Physics at the California Institute of Technology.

    But what makes Schmidt even more compelling to us is his day job. For forty-five years, Schmidt was an efficient and prolific public executioner, employed by the state to extract confessions and put convicted criminals to death. In his years of service, he executed 361 people and tortured, flogged, or disfigured hundreds more. Is it possible that a man who practiced such cruelty could also be insightful, compassionate, humane—even progressive? In his groundbreaking book, the historian Joel F. Harrington looks for the answer in Schmidt’s journal, whose immense significance has been ignored until now. Harrington uncovers details of Schmidt’s medical practice, his marriage to a woman ten years older than him, his efforts at penal reform, his almost touching obsession with social status, and most of all his conflicted relationship with his own craft and the growing sense that it could not be squared with his faith. A biography of an ordinary man struggling for his soul, The Faithful Executioner is also an unparalleled portrait of Europe on the cusp of modernity, yet riven by conflict and encumbered by paranoia, superstition, and abuses of power. In his intimate portrait of a Nuremberg executioner, Harrington also sheds light on our own fraught historical moment.

    Was she the heartless seductress of legend? Or merely an unsuspecting pawn in a familial web, forced to choose between loyalty and her own survival?Glamorous and predatory, the Borgias became Italy’s most ruthless and powerful family, electrifying and terrorizing their 15th-century Renaissance world.To this day, Lucrezia Borgia is known as one of history’s most notorious villainesses, accused of incest and luring men to doom with her arsenal of poison.International bestselling author C.W. Gortner’s new novel delves beyond the myth to depict Lucrezia in her own voice, from her pampered childhood in the palaces of Rome to her ill-fated, scandalous arranged marriages and complex relationship with her adored father and her rival brothers—brutal Juan and enigmatic Cesare.This is the dramatic, untold story of a papal princess who came of age in an era of savage intrigue and unparalleled splendor, and whose courage led her to overcome the fate imposed on her by her Borgia blood.

    But the myth of darkness obscures the truth; this was a remarkable period in human history. The Bright Ages recasts the European Middle Ages for what it was, capturing this 1,000-year era in all its complexity and fundamental humanity, bringing to light both its beauty and its horrors. The Bright Ages takes us through ten centuries and crisscrosses Europe and the Mediterranean, Asia and Africa, revisiting familiar people and events with new light cast upon them. We look with fresh eyes on the Fall of Rome, Charlemagne, the Vikings, the Crusades, and the Black Death, but also to the multi-religious experience of Iberia, the rise of Byzantium, and the genius of Hildegard and the power of queens. We begin under a blanket of golden stars constructed by an empress with Germanic, Roman, Spanish, Byzantine, and Christian bloodlines and end nearly 1,000 years later with the poet Dante—inspired by that same twinkling celestial canopy—writing an epic saga of heaven and hell that endures as a masterpiece of literature today.  The Bright Ages reminds us just how permeable our manmade borders have always been and of what possible worlds the past has always made available to us. The Middle Ages may have been a world “lit only by fire” but it was one whose torches illuminated the magnificent rose windows of cathedrals, even as they stoked the pyres of accused heretics.  The Bright Ages is illustrated throughout with high-resolution images.
