The Middle Ages is not only a period of Romance, but of legends, tales, and mysteries. In this course, Professor Thomas F. Madden guides listeners through the most famous and enduring narratives of medieval Europe. Beginning with King Arthur, Professor Madden peels back layers of exaggeration and fiction to lay bare the historical basis for the mythical king.

A fascinating investigation of the origin of humans based on incredible new discoveries and advanced scientific technology.

Professor Thomas F. Madden is a widely published author and the director of the Center for Medieval and Renaissance Studies at Saint Louis University. In The Lost Warriors of God, Madden examines one of the most fascinating organizations in world history: the Knights Templar, whose members gave up home, family, and worldly possessions to defend the Holy Land and the Christian pilgrims who journeyed there.

Since its 2009 launch, the Kepler satellite has discovered more than 2,000 exoplanets, or planets outside our solar system. More exoplanets are being discovered all the time, remarkable in their variety. Astronomer Michael Summers and physicist James Trefil explore these remarkable recent discoveries: planets revolving around pulsars, planets made of diamond, planets that are mostly water, and numerous rogue planets wandering through the emptiness of space.

My beginner's book is your ticket to one of the coolest and most mysterious subjects out there. This isn't your average physics book. It's a portal to understanding the stuff that makes up... well, everything! Subatomic particles. Do not let their size fool you; they have a massive impact on the world around you—the fundamental part of how everything works and not as complex as you might fear.

Get to know the Greek gods and goddesses, from the mighty Zeus, to the temperamental Poseidon, the beautiful Aphrodite, and every character from A to Z. Who wouldn’t want to hear about Zeus and his command of lightning, Hades and how he found his bride, the wisdom of Athena, and so many other stories that capture the imagination. These stories can do more than just entertain; they can also inspire and teach us lessons that were penned by the Greeks themselves.

At 01:23:40 on April 26th 1986, Alexander Akimov pressed the emergency shutdown button at Chernobyl's fourth nuclear reactor. It was an act that forced the permanent evacuation of a city, killed thousands, and crippled the Soviet Union. The event spawned decades of conflicting, exaggerated, and inaccurate stories.

For more than 50 years, the world's top scientists searched for the "missing" planet Vulcan, whose existence was mandated by Isaac Newton's theories of gravity. Countless hours were spent on the hunt for the elusive orb, and some of the era's most skilled astronomers even claimed to have found it. There was just one problem: It was never there.

In Kindred, Neanderthal expert Becky Wragg Sykes shoves aside the cliché of the shivering ragged figure in an icy wasteland and reveals the Neanderthal you don’t know, who lived across vast and diverse tracts of Eurasia and survived through hundreds of thousands of years of massive climate change. Using a thematic rather than chronological approach, this book will shed new light on where they lived, what they ate and the increasingly complex Neanderthal culture that is being discovered.

In 1851, Olive Oatman was a 13-year-old pioneer traveling west toward Zion, with her Mormon family. Within a decade, she was a white Indian with a chin tattoo, caught between cultures. The Blue Tattoo tells the harrowing story of this forgotten heroine of frontier America. Orphaned when her family was brutally killed by Yavapai Indians, Oatman lived as a slave to her captors for a year before being traded to the Mohave, who tattooed her face and raised her as their own.

In 1994 Professor Bryan Sykes, a leading world authority on DNA and human evolution, was called in to examine the frozen remains of a man trapped in glacial ice in northern Italy. News of both the Ice Man's discovery and his age, which was put at over 5,000 years, fascinated scientists and newspapers throughout the world. But what made Sykes's story particularly revelatory was his successful identification of a genetic descendant of the Ice Man, a woman living in Great Britain today. How was Sykes able to locate a living relative?

In 1994, a team led by fossil-hunting legend Tim White—"the Steve Jobs of paleoanthropology"—uncovered the bones of a human ancestor in Ethiopia's Afar region. The findings challenged many assumptions about human evolution and repudiated a half-century of paleoanthropological orthodoxy. An intriguing tale of scientific discovery, obsession and rivalry that moves from the sun-baked desert of Africa to modern high-tech labs and academic lecture halls, Fossil Men is popular science at its best, and a must-listen for fans of Jared Diamond, Richard Dawkins, and Edward O. Wilson.

Drawing on the latest discoveries that have only recently come to light, Scottish archaeologist Neil Oliver goes on the trail of the real Vikings. Where did they emerge from? How did they really live? And just what drove them to embark on such extraordinary voyages of discovery over 1,000 years ago? The Vikings: A New History explores many of those questions for the first time in an epic story of one of the world's great empires of conquest.

In our unique genomes, every one of us carries the story of our species - births, deaths, disease, war, famine, migration, and a lot of sex. But those stories have always been locked away - until now. Who are our ancestors? Where did they come from? Geneticists have suddenly become historians, and the hard evidence in our DNA has completely upended what we thought we knew about ourselves. Acclaimed science writer Adam Rutherford explains exactly how genomics is completely rewriting the human story - from 100,000 years ago to the present.

Asked to name a great physicist, most people would mention Newton or Einstein, Feynman or Hawking. But ask a physicist and there’s no doubt that James Clerk Maxwell will be near the top of the list. Maxwell, an unassuming Victorian Scotsman, explained how we perceive color. He uncovered the way gases behave. And, most significantly, he transformed the way physics was undertaken in his explanation of the interaction of electricity and magnetism, revealing the nature of light and laying the groundwork for everything from Einstein’s special relativity to modern electronics.

More than 12,000 years ago, in one of the greatest triumphs of prehistory, humans colonized North America, a continent that was then truly a new world. Just when and how they did so has been one of the most perplexing and controversial questions in archaeology.

Fifty thousand years ago - merely a blip in evolutionary time - our Homo sapiens ancestors were competing for existence with several other human species, just as their precursors had done for millions of years. Yet something about our species distinguished it from the pack, and ultimately led to its survival while the rest became extinct. Just what was it that allowed Homo sapiens to become masters of the planet? Ian Tattersall, curator emeritus at the American Museum of Natural History, takes us deep into the fossil record to uncover what made humans so special.

A fascinating investigation of the origin of humans based on incredible new discoveries and advanced scientific technology.

In Born in Africa, Martin Meredith follows the trail of discoveries about human origins made by scientists over the last hundred years, recounting their intense rivalry, personal feuds, and fierce controversies, as well as their feats of skill and endurance. The results have been momentous. Scientists have identified more than 20 species of extinct humans. They have firmly established Africa as the birthplace not only of humankind but also of modern humans.

A Pocket History of Human Evolution brings us up-to-date on the exploits of all our ancient relatives. Paleoanthropologist Silvana Condemi and science journalist François Savatier consider what accelerated our evolution: Was it tools, our "large" brains, language, empathy, or something else entirely? And why are we the sole survivors among many early bipedal humans? Their conclusions reveal the various ways ancient humans live on today - from gossip as modern "grooming" to our gendered division of labor - and what the future might hold for our strange and unique species.

Spectacular fossil finds make today's headlines; new technology unlocks secrets of skeletons unearthed 100 years ago. Still, evolution is often poorly represented by the media and misunderstood by the public. A potent antidote to pseudoscience, Written in Stone is an engrossing history of evolutionary discovery for anyone who has marveled at the variety and richness of life.

Stunning new archaeological discoveries in North America together with new genetic evidence have launched a revolution in our understanding of the remote past of our species and of the origins of civilization. Graham Hancock, the internationally best-selling author has been overwhelmingly vindicated by recent discoveries. America Before: The Key to Earth's Lost Civilization is a mind-dilating exploration of the mystery of ancient civilizations, amazing archaeological discoveries, and profound implications for how we lead our lives today.

We often think of Britain springing from nowhere with the arrival of the Romans. But in Ancestors, pre-eminent archaeologist, broadcaster and academic Professor Alice Roberts explores what we can learn about the very earliest Britons – from their burial sites. Although we have very little evidence of what life was like in prehistorical times, here their stories are told through the bones and funerary offerings left behind, preserved in the ground for thousands of years.

Just in the last three years a flood of new scientific findings, driven by revelations discovered in the human genome, has provided compelling new answers to many long-standing mysteries about our most ancient ancestors, the people who first evolved in Africa and then went on to colonize the whole world. Nicholas Wade weaves this host of news-making findings together for the first time into an intriguing new history of the human story before the dawn of civilization.

One of the most significant works on our evolutionary ancestry since Richard Leakey's Origins, The First Signs is the first-ever exploration of the geometric images that accompany most cave art around the world—the first indications of symbolic meaning, intelligence, and language.

Africa has long been considered the cradle of life - where life and humans evolved - but somewhere west of Munich, Germany, paleoclimatologist and paleontologist Madelaine Böhme and her team make a discovery that is beyond anything they ever imagined: the 12-million-year-old bones of an ancient ape - Danuvius guggenmos - which makes headlines around the world and defies prevailing theories of human history and where human life began.

Who were the first humans to inhabit North America? According to the now familiar story, mammal hunters entered the continent some 12,000 years ago via a land bridge that spanned the Bering Sea. The presence of these early New World people was established by distinctive stone tools belonging to the Clovis culture. But are the Clovis tools Asian in origin? Drawing from original archaeological analysis, paleoclimatic research, and genetic studies, noted archaeologists Dennis J. Stanford and Bruce A. Bradley challenge the old narrative.

Tracing the migrations of the Denisovans and their interbreeding with Neanderthals and early human populations in Asia, Europe, Australia, and the Americas, Andrew Collins and Greg Little explore how the new mental capabilities of the Denisovan-Neanderthal and Denisovan-human hybrids greatly accelerated the flowering of human civilization over 40,000 years ago. They show how the Denisovans displayed sophisticated advances, including precision-machined stone tools and jewelry, tailored clothing, celestially-aligned architecture, and horse domestication.

The monumental statues of Easter Island, both so magisterial and so forlorn, gazing out in their imposing rows over the island’s barren landscape, have been the source of great mystery ever since the island was first discovered by Europeans on Easter Sunday 1722. How could the ancient people who inhabited this tiny speck of land, the most remote in the vast expanse of the Pacific islands, have built such monumental works?

Some 73,000 years ago, the Mount Toba supervolcano in toda's Indonesia erupted, releasing the energy of a million tons of explosives. So much ash and debris was injected into the stratosphere that it partially blocked the sun's radiation and caused global temperatures to drop for a decade. In this book, Donald R. Prothero presents the controversial argument that the Toba catastrophe nearly wiped out the human race, leaving only about a thousand to ten thousand breeding pairs of humans worldwide.

A preeminent geneticist hunts the Neanderthal genome to answer the biggest question of them all: what does it mean to be human? What can we learn from the genes of our closest evolutionary relatives? Neanderthal Man tells the story of geneticist Svante Pbo’s mission to answer that question, beginning with the study of DNA in Egyptian mummies in the early 1980s and culminating in his sequencing of the Neanderthal genome in 2009.

A giant of archaeology, Colin Renfrew has immeasurably improved our understanding of human history. In this passionately argued work, he offers a concise summary of prehistory - human existence that predates the development of written records - while challenging the very definition of prehistory itself.

In Kindred, Neanderthal expert Becky Wragg Sykes shoves aside the cliché of the shivering ragged figure in an icy wasteland and reveals the Neanderthal you don’t know, who lived across vast and diverse tracts of Eurasia and survived through hundreds of thousands of years of massive climate change.

J. M. Adovasio has spent the last thirty years at the center of one of our most fiery scientific debates: Who were the first humans in the Americas, and how and when did they get there? At its heart, The First Americans is the story of the revolution in thinking that Adovasio and his fellow archaeologists have brought about, and the firestorm it has ignited.

Slimak has travelled around the world for the past thirty years to uncover who the Neanderthals really were. A modern-day Indiana Jones, he takes us on a fascinating archaeological investigation: from the Arctic Circle to the deep Mediterranean forests, he traces the steps of these enigmatic creatures, working to decipher their real stories through every single detail they left behind.

Neanderthals have developed a radically different civilization on a parallel Earth. A Neanderthal physicist, Ponter Boddit, accidentally passes from his universe into a Canadian underground research facility. Fortunately, a team of human scientists, including expert paleo-anthropologist Mary Vaughan, promptly identifies and warmly receives Ponter. Solving the language problem and much else is a mini-computer, called a Companion, implanted in the brain of every Neanderthal. But it can't help his fellow scientist back in his world, Adikor Huld, when the authorities charge Adikor with his murder.
