    That one bite changed her life forever, pulling her into the abyss of a devastating illness that took ten doctors to diagnose and years to recover: Newby had become one of the 300,000 Americans who are afflicted with Lyme disease each year.As a science writer, she was driven to understand why this disease is so misunderstood, and its patients so mistreated. This quest led her to Willy Burgdorfer, the Lyme microbe's discoverer, who revealed that he had developed bug-borne bioweapons during the Cold War, and believed that the Lyme epidemic was started by a military experiment gone wrong.In a superb, meticulous work of narrative journalism, Bitten takes readers on a journey to investigate these claims, from biological weapons facilities to interviews with biosecurity experts and microbiologists doing cutting-edge research, all the while uncovering darker truths about Willy. It also leads her to uncomfortable questions about why Lyme can be so difficult to both diagnose and treat, and why the government is so reluctant to classify chronic Lyme as a disease.A gripping, infectious page-turner, Bitten will shed a terrifying new light on an epidemic that is exacting an incalculable toll on us, upending much of what we believe we know about it.

    As much as we'd like to cultivate these same skills, the truth is that you cannot know how a lawyer thinks and works without studying the law itself.Now there's an easier way to get the same foundational knowledge as lawyers - without the enormous time and financial commitment. Over the span of 48 lectures, four experienced lawyers and teachers recreate key parts of the first-year law student experience, introducing you to main areas of law most every beginning student studies.You'll start with 12 lectures on litigation and legal practice that offer eye-opening answers to many questions about the art and craft of legislation. In the second 12 lectures, you'll learn how criminal law and procedure - an area of law dramatized by countless TV shows - really works. Additional lectures investigate the civic procedures courts follow to resolve disputes about substantive rights and examine broader questions any system of litigation must address. And 12 lectures are devoted entirely to the stranger-than-fiction topic of tort law.Enriched with famous cases from the annals of American law and powerful arguments by some of history's most successful lawyers, these lectures offer access to an often intimidating, surprisingly accessible, and civically important field.

    But for thousands of years, people have done things like this—and things that make radioactive underpants seem downright sensible! In their hit podcast, Sawbones, Sydnee and Justin McElroy breakdown the weird and wonderful way we got to modern healthcare. And some of the terrifying detours along the way.Every week, Dr. Sydnee McElroy and her husband Justin amaze, amuse, and gross out (depending on the week) hundreds of thousands of avid listeners to their podcast, Sawbones. Consistently rated a top podcast on iTunes, with over 15 million total downloads, this rollicking journey through thousands of years of medical mishaps and miracles is not only hilarious but downright educational. While you may never even consider applying  boiled weasel to your forehead (once the height of sophistication when it came to headache cures), you will almost certainly face some questionable medical advice in your everyday life (we’re looking at you, raw water!) and be better able to figure out if this is a miracle cure (it’s not) or a scam.

    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.

    But the surprising truth is that Genghis Khan was a visionary leader whose conquests joined backward Europe with the flourishing cultures of Asia to trigger a global awakening, an unprecedented explosion of technologies, trade, and ideas. In Genghis Khan and the Making of the Modern World, Jack Weatherford, the only Western scholar ever to be allowed into the Mongols’ “Great Taboo”—Genghis Khan’s homeland and forbidden burial site—tracks the astonishing story of Genghis Khan and his descendants, and their conquest and transformation of the world. Fighting his way to power on the remote steppes of Mongolia, Genghis Khan developed revolutionary military strategies and weaponry that emphasized rapid attack and siege warfare, which he then brilliantly used to overwhelm opposing armies in Asia, break the back of the Islamic world, and render the armored knights of Europe obsolete. Under Genghis Khan, the Mongol army never numbered more than 100,000 warriors, yet it subjugated more lands and people in twenty-five years than the Romans conquered in four hundred. With an empire that stretched from Siberia to India, from Vietnam to Hungary, and from Korea to the Balkans, the Mongols dramatically redrew the map of the globe, connecting disparate kingdoms into a new world order. But contrary to popular wisdom, Weatherford reveals that the Mongols were not just masters of conquest, but possessed a genius for progressive and benevolent rule. On every level and from any perspective, the scale and scope of Genghis Khan’s accomplishments challenge the limits of imagination. Genghis Khan was an innovative leader, the first ruler in many conquered countries to put the power of law above his own power, encourage religious freedom, create public schools, grant diplomatic immunity, abolish torture, and institute free trade. The trade routes he created became lucrative pathways for commerce, but also for ideas, technologies, and expertise that transformed the way people lived. The Mongols introduced the first international paper currency and postal system and developed and spread revolutionary technologies like printing, the cannon, compass, and abacus. They took local foods and products like lemons, carrots, noodles, tea, rugs, playing cards, and pants and turned them into staples of life around the world. The Mongols were the architects of a new way of life at a pivotal time in history. In Genghis Khan and the Making of the Modern World, Jack Weatherford resurrects the true history of Genghis Khan, from the story of his relentless rise through Mongol tribal culture to the waging of his devastatingly successful wars and the explosion of civilization that the Mongol Empire unleashed. This dazzling work of revisionist history doesn’t just paint an unprecedented portrait of a great leader and his legacy, but challenges us to reconsider how the modern world was made.From the Hardcover edition.

    At the dawn of the 21st millennium the world is still experiencing these anxieties, as seen by the onslaught of fantasies of renewal, doomsday predictions, and New Age prophecies.This fascinating book explores the millenarianism that flourished in western Europe between the eleventh and sixteenth centuries. Covering the full range of revolutionary and anarchic sects and movements in medieval Europe, Cohn demonstrates how prophecies of a final struggle between the hosts of Christ and Antichrist melded with the rootless poor's desire to improve their own material conditions, resulting in a flourishing of millenarian fantasies. The only overall study of medieval millenarian movements, The Pursuit of the Millennium offers an excellent interpretation of how, again and again, in situations of anxiety and unrest, traditional beliefs come to serve as vehicles for social aspirations and animosities.

    And with the advent of modern science, great minds have turned to testing and experimentation rather than mere thought as a way of approaching and grappling with some of the universe's most pressing and vexing dilemmas. So what is our latest picture of some of the most inexplicable features of the universe? What still remains to be uncovered? What are some of the next avenues of exploration for today's chemists, physicists, biologists, and astronomers? Pondering the answers to these and other questions is a great way to appreciate the grandeur and complexity of the world around you, better understand and discuss news and developments in science, and spark further interest in some of science's many exciting areas of study. "We know a lot about the universe. But there's even more that we don't know,"says astrophysicist and Professor Neil deGrasse Tyson, director of the Hayden Planetarium, an award-winning lecturer, and one of the world's foremost experts on the secrets of the universe. And his course The Inexplicable Universe: Unsolved Mysteries is the perfect gateway into this mind-bending and eye-opening subject. Each of these six self-contained lectures is a marvelous journey to the frontiers of the known (and unknown) universe and introduces you to tantalizing questions being addressed by the world's top scientists. Undeniably engaging and fascinating, this lecture series is a wonderful entrée to scientific pursuits that lie at the very heart of the history and nature of our universe. An Informed Scientific Conversation Central to The Inexplicable Universe is the way it takes you deep into hidden layers of the universe in a manner that is extremely accessible. Rather than a stern lecture given before a podium complete with confusing mathematics, Professor Tyson's lectures have the feel of an informed conversation that manages to be both thorough and easy to grasp. With each of the inexplicable mysteries he lays bare for you, Professor Tyson introduces you to the history behind it, lays out the science that has helped us grasp it, explains what researchers have discovered to date, and reveals what we have yet to discover. And while the topics explore subjects in everything from quantum mechanics to cosmology to string theory, you'll never feel overwhelmed by what you're learning. In fact, you're more likely to find yourself intrigued by just how much we know-and curious about what the near future will possibly reveal. Explore Fascinating Territory So what territory will you chart in this course? Here are some of the inexplicable ideas you'll investigate in these lectures. Neutrinos: Discovered in 1956, these fast-moving, ghostlike particles are made in abundance in the sun's core. They hardly interact with matter; it takes a light-year's worth of lead (5.8 trillion miles) to stop a neutrino. Not only that, but 65 billion neutrinos pass through every centimeter of your body that's facing the sun every second of every day. String theory: This astounding theory offers the hope of unifying all the particles and forces of physics. In the past several decades since the dawn of string theory, it's been imagined that all the fundamental particles we see and measure are just the manifestation in our dimension of strings vibrating in higher dimensions and at different frequencies. Quantum foam: This idea posits that when the fabric of space and time is so tightly curved on itself, space-time is less a smooth curve and more like the froth on a latte. In this state of matter and energy, quantum fluctuations can spawn entire universes, each with slightly different laws of physics within them! In addition, you'll also get a peek at what it would be like to travel through a black hole, ponder the possibility that life on Earth originated in debris from Mars, probe the supposed existence of multiple universes, and even imagine the possible end of the universe itself. A One-on-One Chat with a Renowned Science Educator Professor Tyson is renowned throughout the scientific community and the media for his vast knowledge, his penetrating insights, and his amazing ability to make even the most intimidating areas of science accessible, engaging, and-most of all-enjoyable. He brings the same inviting tone and sharp intellect to The Inexplicable Universe as he does to his range of media appearances on popular television programs. Due to its unique subject matter The Inexplicable Universe takes a highly visual approach. Many of the fascinating subjects in the course, such as black holes, string theory, and multiple universes are best demonstrated visually and Professor Tyson's lectures feature expertly crafted computer animations, explanatory diagrams, high resolution photographs, and other instructive visual elements. In order to better explain to you some of the grand, intricate ideas being discussed, Professor Tyson personally interacts with many of these animations and graphics using greenscreen technology. Please note that, due to the highly visual nature of The Inexplicable Universe, the course does not come with a guidebook. We did not believe a simple book could adequately convey the information in the course, and rather than make a guidebook that did not do the course justice, we decided to not offer one. However, we believe that you will be very excited by how we produced this course and will find it to be an enriching and fulfilling experience in your educational journey.

    You'll spend a week on this for sure.A History of the Middle Ages is the amazing story of European man in transition. It is a dramatic chronicle of 1,000 years of political, social, and economic transformation beginning with the dissolution of the classical Mediterranean civilization and ending with the first flowering of the Renaissance. It is also the story of two new religions, Christianity and Islam, both of which were destined to dominate the mind of every person in those new civilizations arising in their wake. This was the great Age of Faith, a time of darkness and a time of enlightenment...a time of lords and vassals, popes and kings, and commerce and cathedrals.Size of Audible Audio Book: 1146 minutes in 3 partsPart 1: 6 hr 15 minPart 2: 6 hr 29 minPart 3: 6 hr 22 min

    For millennia Europeans believed that the world consisted of three parts: Europe, Africa, and Asia. They drew the three continents in countless shapes and sizes on their maps, but occasionally they hinted at the existence of a "fourth part of the world," a mysterious, inaccessible place, separated from the rest by a vast expanse of ocean. It was a land of myth--until 1507, that is, when Martin Waldseemuller and Matthias Ringmann, two obscure scholars working in the mountains of eastern France, made it real. Columbus had died the year before convinced that he had sailed to Asia, but Waldseemuller and Ringmann, after reading about the Atlantic discoveries of Columbus's contemporary Amerigo Vespucci, came to a startling conclusion: Vespucci had reached the fourth part of the world. To celebrate his achievement, Waldseemuller and Ringmann printed a huge map, for the first time showing the New World surrounded by water and distinct from Asia, and in Vespucci's honor they gave this New World a name: America."The Fourth Part of the World "is the story behind that map, a thrilling saga of geographical and intellectual exploration, full of outsize thinkers and voyages. Taking a kaleidoscopic approach, Toby Lester traces the origins of our modern worldview. His narrative sweeps across continents and centuries, zeroing in on different portions of the map to reveal strands of ancient legend, Biblical prophecy, classical learning, medieval exploration, imperial ambitions, and more. In Lester's telling the map comes alive: Marco Polo and the early Christian missionaries trek across Central Asia and China; Europe's early humanists travel to monastic libraries to recover ancient texts; Portuguese merchants round up the first West African slaves; Christopher Columbus and Amerigo Vespucci make their epic voyages of discovery; and finally, vitally, Nicholas Copernicus makes an appearance, deducing from the new geography shown on the Waldseemuller map that the earth could not lie at the center of the cosmos. The map literally altered humanity's worldview.One thousand copies of the map were printed, yet only one remains. Discovered accidentally in 1901 in the library of a German castle it was bought in 2003 for the unprecedented sum of $10 million by the Library of Congress, where it is now on permanent public display. Lavishly illustrated with rare maps and diagrams, "The Fourth Part of the World "is the story of that map: the dazzling story of the geographical and intellectual journeys that have helped us decipher our world.

    As audacious as it is edifying, here is a hilarious and irreverent—yet always historically accurate—overview of the ascent (or descent) of humankind, courtesy of the same rebel geniuses who brought you Mental Floss presents Condensed Knowledge and Mental Floss Presents Forbidden Knowledge. Updated with all the hot topics and events of the past few years, The Mental Floss History of the World is proof positive that just because something’s true doesn’t mean it’s boring.

    The media seized hold of the story and, in the process, helped to launch one of the most devastating health scares ever. In the years to come Wakefield would be revealed as a profiteer in league with class-action lawyers, and he would eventually lose his medical license. Meanwhile, one study after another failed to find any link between childhood vaccines and autism. Yet the myth that vaccines somehow cause developmental disorders lives on. Despite the lack of corroborating evidence, it has been popularized by media personalities such as Oprah Winfrey and Jenny McCarthy and legitimized by journalists who claim that they are just being fair to “both sides” of an issue about which there is little debate. Meanwhile, millions of dollars have been diverted from potential breakthroughs in autism research; families have spent their savings on ineffective “miracle cures"; and declining vaccination rates have led to outbreaks of deadly illnesses like Hib, measles, and whooping cough. Most tragic of all is the increasing number of children dying from vaccine-preventable diseases. In The Panic Virus Seth Mnookin draws on interviews with parents, public-health advocates, scientists, and anti-vaccine activists to tackle a fundamental question: How do we decide what the truth is? The fascinating answer helps explain everything from the persistence of conspiracy theories about 9/11 to the appeal of talk-show hosts who demand that President Obama “prove” he was born in America. The Panic Virus is the ultimate cautionary tale for our time.

    In all the annals of the ancient world, few stories are more gripping than those from this era.In the opening lectures, you'll explore the enigma of Alexander, son of a brilliant father, yet always at odds with the man whom he succeeded. You'll trace his early campaigns against the Persians and follow him to Egypt, where he was acclaimed as the son of god. You'll then look at his career after this and find in him a blend of greatness and madness as he strove to replace the Persian empire of the Achaemenid dynasty with a new, mixed ruling class of Macedonians and Persians.From there, you'll delve into the catastrophic period after Alexander's death in 323 B.C., which ushered in a period of catastrophic change as ambitious warlords carved up Alexander's realm into their own separate empires. You'll learn about each of the three kingdoms that resulted: Ptolemaic Egypt, Seleucid Syria, and the Attalid Empire in Asia Minor. Just as important to these lectures are the in-depth discussions of the bounties of Hellenistic culture, which contributed landmark ideas in everything from philosophy (which became more academic), art and architecture (with its excessive, naked emotions), and religion (especially the growing popularity of cult movements). Taken all together, these lectures are an engrossing and riveting journey into ancient history-and the life and times of the man who left an indelible mark on everything that would come after.

    To understand the unfolding of Spain's epic history is to come to terms with one of the West's great cultures, and to grasp its enduring presence and impact on the world stage.In these 24 accessible lectures, Professor Salisbury presents a broad and enthralling panorama of Spanish history, covering the centuries from the first prehistoric settlement of the peninsula to Spain's 20th-century civil war.Linking one seminal era with the next, the course begins with how early Spain drew a range of peoples from ancient Africa, the Mediterranean, and the Middle East, who formed vibrant communities on the peninsula. From there, you'll witness the rule of the peninsula by both Rome and Visigothic peoples, leading to the spellbinding drama of Islamic Spain and the Reconquista, Catholic Spain and the Inquisition, and the opening of the New World. Finally, you'll travel into the kingly dynasties and the dazzling artistic heritage of the Habsburgs and Bourbons, and you'll track Spain's emergence into the modern world.Together with the unfolding of Spanish history, Professor Salisbury illuminates Spain's iconic cultural forms - such as flamenco music and dance, and the ritual of bullfighting - and its phenomenal contributions to art, architecture, literature, music, theology, and learning.Across the centuries, you'll explore jewels of Spanish architecture, from the resplendent Moorish Alhambra and Alcázar of Seville to the sublime Sagrada Familia cathedral of modernist Antoni Gaudí. And you'll encounter Spain's geniuses of the visual and written arts, including such masters as the painters Velasquez, el Greco, Goya, and Picasso, and writers from the philosophers Averroes and Maimonides to literary greats Lope de Vega and Cervantes.Travel with us to this remarkable culture, and savor the beauty and the great human drama of the history of Spain.
