It ranges from the study of the universe itself to the smallest particles of matter contained within it - and everything in between. It explores everything from the big bang to theories about the end of the universe. If you want to better understand our physical world, as most of us do, gaining a basic understanding of science itself is profoundly important - yet many are intimidated by the breathtaking scope of such an endeavor. Now an award-winning science teacher has taken out the intimidation, harnessing that breathtaking scope into a series of 60 exciting, comprehensive, and accessible lectures that let you explore and understand the wealth of ideas, discoveries, and principles in all of the physical and biological sciences. You learn that understanding science comes from understanding not only its component disciplines - each of which has its own theories, pioneers, problems, and fundamental questions - but of knowing how these disciplines work with one another to create an entire mosaic of human knowledge. The lectures have been crafted to make those relationships crystal-clear, with an integrated approach that takes you through all of the major disciplines that fall under the umbrella of "science," including physics, chemistry, Earth science, geophysics, and biology. Each lecture covers one of the 60 fundamental principles of the scientific world - offering you new knowledge and insight into topics such as the scientific method, gravitation, atoms, the big bang, plate tectonics, volcanoes, proteins, ecosystems, and electricity.

    In it, we follow them from sixth-century Alexandria to ninth-century Baghdad, from Muslim Cordoba to Catholic Toledo, from Salerno’s medieval medical school to Palermo, capital of Sicily’s vibrant mix of cultures and – finally – to Venice, where that great merchant city’s printing presses would enable Euclid’s geometry, Ptolemy’s system of the stars and Galen’s vast body of writings on medicine to spread even more widely. In tracing these fragile strands of knowledge from century to century, from east to west and north to south, Moller also reveals the web of connections between the Islamic world and Christendom, connections that would both preserve and transform astronomy, mathematics and medicine from the early Middle Ages to the Renaissance. Vividly told and with a dazzling cast of characters, The Map of Knowledge is an evocative, nuanced and vibrant account of our common intellectual heritage.

    

    Thomas Asbridge—a renowned historian who writes with “maximum vividness” (Joan Acocella, The New Yorker)—covers the years 1095 to 1291 in this  big, ambitious, readable account of one of the most fascinating periods in history. From Richard the Lionheart to the mighty Saladin, from the emperors of Byzantium to the Knights Templar, Asbridge’s book is a magnificent epic of Holy War between the Christian and Islamic worlds, full of adventure, intrigue, and sweeping grandeur.

    The celebrated Macedonian king has been one of the most enduring figures in history. He was a general of such skill and renown that for two thousand years other great leaders studied his strategy and tactics, from Hannibal to Napoleon, with countless more in between. He flashed across the sky of history like a comet, glowing brightly and burning out quickly: crowned at age nineteen, dead by thirty-two. He established the greatest empire of the ancient world; Greek coins and statues are found as far east as Afghanistan. Our interest in him has never faded. Alexander was born into the royal family of Macedonia, the kingdom that would soon rule over Greece. Tutored as a boy by Aristotle, Alexander had an inquisitive mind that would serve him well when he faced formidable obstacles during his military campaigns. Shortly after taking command of the army, he launched an invasion of the Persian empire, and continued his conquests as far south as the deserts of Egypt and as far east as the mountains of present-day Pakistan and the plains of India. Alexander spent nearly all his adult life away from his homeland, and he and his men helped spread the Greek language throughout western Asia, where it would become the lingua franca of the ancient world. Within a short time after Alexander’s death in Baghdad, his empire began to fracture. Best known among his successors are the Ptolemies of Egypt, whose empire lasted until Cleopatra. In his lively and authoritative biography of Alexander, classical scholar and historian Philip Freeman describes Alexander’s astonishing achievements and provides insight into the mercurial character of the great conqueror. Alexander could be petty and magnanimous, cruel and merciful, impulsive and farsighted. Above all, he was ferociously, intensely competitive and could not tolerate losing—which he rarely did. As Freeman explains, without Alexander, the influence of Greece on the ancient world would surely not have been as great as it was, even if his motivation was not to spread Greek culture for beneficial purposes but instead to unify his empire. Only a handful of people have influenced history as Alexander did, which is why he continues to fascinate us.

    See the city through their eyes as it teeters on the edge of the fateful war that would end its golden age. Athens, 416 BC. A tenuous peace holds. The city-state's political and military might are feared throughout the ancient world; it pushes the boundaries of social, literary and philosophical experimentation in an era when it has a greater concentration of geniuses per capita than at any other time in human history. Yet even geniuses go to the bathroom, argue with their spouse and enjoy a drink with friends.Few of the city's other inhabitants enjoy the benefits of such a civilized society, though - as multicultural and progressive as Athens can be, many are barred from citizenship. No, for the average person, life is about making ends meet, whether that be selling fish, guarding the temple or smuggling lucrative Greek figs.During the course of a day we meet 24 Athenians from all strata of society - from the slave-girl to the councilman, the vase painter to the naval commander, the housewife to the hoplite - and get to know what the real Athens was like by spending an hour in their company. We encounter a different one of these characters every chapter, with each chapter forming an hour in the life of the ancient city. We also get to spy on the daily doings of notable Athenians through the eyes of regular people as the city hovers on the brink of the fateful war that will destroy its golden age.

    Drout is at his best when lecturing on the fascinating history, language, and societal adaptations of the Anglo-Saxons.

    Armed with spears or pikes, standing shoulder-to-shoulder and with overlapping shields, they presented an impenetrable wall of metal to the enemy until the Roman legion eclipsed the phalanx as the masters of infantry battle.Covering the period in which the legion and phalanx clashed (280-168 BC), this book looks at each formation in detail - delving into their tactics, arms and equipment, organization and deployment. It then examines six documented battles in which the legion fought the phalanx: Heraclea (280 BC), Asculum (279 BC), Beneventum (275 BC), Cynoscephalae (197 BC), Magnesia (190 BC), and Pydna (168 BC).

    Allitt transports listeners to England in the 1840s and 1850s. During those two decades, Queen Victoria’s husband, Prince Albert, became one of the most influential people in the country and remains a figure of fascination even today. In fact, the British royal family as we know it wouldn’t exist without the private and public actions of this detached, impartial, and upright political figure.During his brief life of only 42 years, Prince Albert gave the world the new Houses of Parliament and the Great Exhibition of 1851. He helped Great Britain nimbly dodge the violent revolutions sweeping through mainland Europe and played important roles in both the Crimean War and the American Civil War. Trusted by politicians 25 years his senior, Prince Albert was a negotiator with superior insight into the minds of foreign leaders like Abraham Lincoln. Finally, he was husband to an iconic queen who would define an entire era in British history.Parliamentary leaders come and go, but the British monarchy endures. Listeners will learn what great debt the monarchy owes to Prince Albert.Length: 4 hrs and 28 mins

    Lucy Worsley takes us through the bedroom, bathroom, living room and kitchen, covering the architectural history of each room, but concentrating on what people actually did in bed, in the bath, at the table, and at the stove.

    But have you ever wondered how a religion that doesn't even have a god could have accomplished this?Now you have the opportunity to have your questions answered, as this series of 24 lectures by an award-winning teacher traces the history, principles, and evolution of a theology that is both familiar and foreign.You'll learn the astonishing story of Siddhartha Gautama - who was to become the Buddha, or "enlightened one" - the Indian prince who abandoned wife, son, and a privileged life to seek the meaning of life and death, and whose "awakening" and subsequent teachings have since impacted the world as few others have.And you'll learn what happened after his death, as his followers began to share his teachings about the "Four Noble Truths" and the "Path" to Enlightenment. You'll see how Buddhist beliefs underwent significant and even radical change, with different varieties of Buddhism having to take shape as those beliefs spread across India, Central Asia, China, Japan, and virtually every corner of the Western world, such as becoming more respectful of one's duties to family and ancestors in China or becoming reconciled with local deities in Japan.

    The issues Professor Dalton addresses in these lectures - and in Western political theory generally - fall into three sets of fundamental questions you'll get to unpack. The first set involves the essential characteristics of human nature and the good society. The second focuses on the intricate relationship between the individual and society. And the final set of questions involves theories about change.Through these lectures and their historical case studies, you'll be able to identify the fundamental questions and concerns that shape classical and modern political theory:Describe the influence of one's understanding of human nature upon one's vision of the good society.Compare and contrast the views of theorists regarding the purpose of the state, the relationship between politics and ethics, and the qualifications for exercising political power.Discuss views of leading political theorists regarding the meaning of freedom, the sources of legitimate political authority, and the obligations of individuals to the state or society, and more.

    As traders and raiders, explorers and colonists, they reshaped the world between eastern North America and the Asian steppe. For a millennium, though, their history has largely been filtered through the writings of their victims. Based on the latest archaeological and textual evidence, Children of Ash and Elm tells the story of the Vikings on their own terms: their politics, their cosmology, their art and culture. From Björn Ironside, who led an expedition to sack Rome, to Gudrid Thorbjarnardóttir, the most travelled woman in the world, Price shows us the real Vikings, not the caricatures they have become in popular culture and history.

    Lowly born, he rose to prominence as he spread his vision of the redemption of the world. He attracted the attention of faithful disciples and suspicious local authorities. Eventually, he was tried, convicted, and executed.Today, his story is known the world over. And yet, more than two millennia later, great thinkers and everyday people still struggle to answer a single question: Who is Jesus? * Was he a wise sage who culled powerful teachings from centuries of Jewish tradition to create a new world vision of peace and love? * Or was he indeed God himself, the embodiment of divinity on earth, sent to bring salvation and redemption from sin? * Did his promise of salvation apply to all humankind or was it limited to only a few followers? And how could one participate in that promise?Since the earliest days of the faith, questions like these have been at the heart of Christianity. Over the centuries, they have led to fierce debate and produced deep divisions among the faithful. These questions have driven profound acts of faith and worship and incited war and persecution. They have contributed to the building of nations and the shaping of lives and have deeply influenced some of the greatest thinkers of Western philosophy. To ponder questions like these is to understand the very shape of the Western world and to comprehend the remarkable power Christian faith has in the life of believers.Now, in The History of Christian Theology, you have an opportunity to explore these profound questions and the many responses believers, scholars, and theologians have developed over more than 2,000 years. Through this 36-lecture course, award-winning Professor Phillip Cary of Eastern University reveals the enduring power of the Christian tradition—as both an intellectual discipline and a spiritual path.Through this course, you will gain thought-provoking insights into a set of teachings that changed the world and discover how, by learning about the diverse beliefs and practices within the wider Christian community, you can enrich your own experience of this great faith.

    Esposito guides you through the facts and myths surrounding Islam and its more than 1.2 billion adherents. How familiar are you with the world's second largest and fastest-growing religion?Many in the West know little about the faith and are familiar only with the actions of a minority of radical extremists.This course will help you better understand Islam's role as both a religion and a way of life, and its deep impact on world affairs both historically and today. It is important to understand what Muslims believe, and also how their beliefs are carried out privately and publicly as individuals as well as members of a larger community."The focus of this course will be to better understand Islam's role as a religion and as a way of life," says Professor Esposito. "In 12 lectures, moving from Muhammad to the present, from the 7th to the 21st centuries, we will explore Muslim beliefs, practices, and history in the context of its significance and impact on Muslim life and society through the ages, as well as world events today."
