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.

    Alexander von Humboldt (1769 – 1859) was an intrepid explorer and the most famous scientist of his age. In North America, his name still graces four counties, thirteen towns, a river, parks, bays, lakes, and mountains. His restless life was packed with adventure and discovery, whether he was climbing the highest volcanoes in the world or racing through anthrax-infected Siberia or translating his research into bestselling publications that changed science and thinking. Among Humboldt's most revolutionary ideas was a radical vision of nature, that it is a complex and interconnected global force that does not exist for the use of humankind alone. Now Andrea Wulf brings the man and his achievements back into focus: his daring expeditions and investigation of wild environments around the world and his discoveries of similarities between climate and vegetation zones on different continents. She also discusses his prediction of human-induced climate change, his remarkable ability to fashion poetic narrative out of scientific observation, and his relationships with iconic figures such as Simón Bolívar and Thomas Jefferson. Wulf examines how Humboldt's writings inspired other naturalists and poets such as Darwin, Wordsworth, and Goethe, and she makes the compelling case that it was Humboldt's influence that led John Muir to his ideas of natural preservation and that shaped Thoreau's Walden.With this brilliantly researched and compellingly written book, Andrea Wulf shows the myriad fundamental ways in which Humboldt created our understanding of the natural world, and she champions a renewed interest in this vital and lost player in environmental history and science.

    This is but a fraction of one man’s life spent collecting every book on every subject – including antique and modern worlds, science and law, as well as playing cards, pornography, and popular music.Who was Hernando Columbus and how did he achieve this?Set to the backdrop of Christopher Columbus’ paradigm-defining explorations of the New World and beyond, and cutting across events of the Renaissance and Reformation, this book follows Hernando Columbus’ bibliomania and curation of the first ever library of its kind.

    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.

    Much as Brainiac offered a behind-the-scenes look at the little-known demimonde of competitive trivia buffs, Maphead finally gives equal time to that other downtrodden underclass: America's map nerds.In a world where geography only makes the headlines when college students are (endlessly) discovered to be bad at it, these hardy souls somehow thrive. Some crisscross the map working an endless geographic checklist: visiting all 3,143 U.S. counties, for example, or all 936 UNESCO World Heritage Sites. Some pore over million-dollar collections of the rarest maps of the past; others embrace the future by hunting real-world cartographic treasures like "geocaches" or "degree confluences" with GPS device in hand. Some even draw thousands of their own imaginary maps, lovingly detailing worlds that never were.Ken Jennings was a map nerd from a young age himself, you will not be surprised to learn, even sleeping with a bulky Hammond atlas at the side of his pillow, in lieu of the traditional Teddy bear. As he travels the nation meeting others of his tribe--map librarians, publishers, "roadgeeks," pint-sized National Geographic Bee prodigies, the computer geniuses behind Google Maps and other geo-technologies--he comes to admire these geographic obsessives. Now that technology and geographic illiteracy are increasingly insulating us from the lay of the land around us, we are going to be needing these people more than ever. Mapheads are the ones who always know exactly where they are--and where everything else is as well.

    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.

    Based on original material and previously unavailable documents, this acclaimed book is the definitive biography of the man considered by many to be the founding father of modern electrical technology. Among Tesla's creations were the channeling of alternating current, fluorescent and neon lighting, wireless telegraphy, and the giant turbines that harnessed the power of Niagara Falls.

    Indians armed with poison-tipped arrows haunt its shadows; piranhas glide through its waters; boulder-strewn rapids turn the river into a roiling cauldron.After his humiliating election defeat in 1912, Roosevelt set his sights on the most punishing physical challenge he could find, the first descent of an unmapped, rapids-choked tributary of the Amazon. Together with his son Kermit and Brazil’s most famous explorer, Cândido Mariano da Silva Rondon, Roosevelt accomplished a feat so great that many at the time refused to believe it. In the process, he changed the map of the western hemisphere forever.Along the way, Roosevelt and his men faced an unbelievable series of hardships, losing their canoes and supplies to punishing whitewater rapids, and enduring starvation, Indian attack, disease, drowning, and a murder within their own ranks. Three men died, and Roosevelt was brought to the brink of suicide. The River of Doubt brings alive these extraordinary events in a powerful nonfiction narrative thriller that happens to feature one of the most famous Americans who ever lived.From the soaring beauty of the Amazon rain forest to the darkest night of Theodore Roosevelt’s life, here is Candice Millard’s dazzling debut.

    For 10 years, he had wandered the forests and death-filled rivers in search of a "lost" cities; convinced he knew the location of one, he headed off for the last time--never to be heard from again. The thrilling story of what occurred during that time has now been compiled by his son from manuscripts, letters, and logbooks. What happened to him after remains a mystery. "...should be read by everyone."--Daily Telegraph.

    But the expedition went horribly wrong: Delayed by a hurricane, knocked off course by a colossal error of navigation, and ultimately doomed by a disastrous decision to separate the men from their ships, the mission quickly became a desperate journey of survival. Of the four hundred men who had embarked on the voyage, only four survived-three Spaniards and an African slave. This tiny band endured a horrific march through Florida, a harrowing raft passage across the Louisiana coast, and years of enslavement in the American Southwest. They journeyed for almost ten years in search of the Pacific Ocean that would guide them home, and they were forever changed by their experience. The men lived with a variety of nomadic Indians and learned several indigenous languages. They saw lands, peoples, plants, and animals that no outsider had ever before seen. In this enthralling tale of four castaways wandering in an unknown land, Andres Resendez brings to life the vast, dynamic world of North America just a few years before European settlers would transform it forever.

    During this time he has broken into a Space Station with a Swiss army knife, disposed of a live snake while piloting a plane, and been temporarily blinded while clinging to the exterior of an orbiting spacecraft. The secret to Col. Hadfield's success-and survival-is an unconventional philosophy he learned at NASA: prepare for the worst-and enjoy every moment of it. In An Astronaut's Guide to Life on Earth, Col. Hadfield takes readers deep into his years of training and space exploration to show how to make the impossible possible. Through eye-opening, entertaining stories filled with the adrenaline of launch, the mesmerizing wonder of spacewalks, and the measured, calm responses mandated by crises, he explains how conventional wisdom can get in the way of achievement-and happiness. His own extraordinary education in space has taught him some counterintuitive lessons: don't visualize success, do care what others think, and always sweat the small stuff. You might never be able to build a robot, pilot a spacecraft, make a music video or perform basic surgery in zero gravity like Col. Hadfield. But his vivid and refreshing insights will teach you how to think like an astronaut, and will change, completely, the way you view life on Earth-especially your own.

    A Short History of the World takes readers from the Mayans to Mongolia, from the kingdom of Benin to the court of the Jagiellonian kings of Poland. Traditional histories of this kind have tended to be Eurocentric, telling mankind's story through tales of Greece and Rome and the crowned heads of Europe's oldest monarchies. Here, Marr widens the lens, concentrating as much, if not more on the Americas, Africa, and Asia. Instead of focusing on one episode of history taking place in one place, he draws surprising parallels and makes fascinating connections, focusing on a key incident or episode to tell a larger story: for instance, the liberation of the serfs in Russia, which took place at the same time as the American Civil War, which resulted in the abolition of slavery in the U.S.  But he begins the account with an episode in the life of Tolstoy, who racked up huge gambling debts and had to sell land and slaves as a result. Fresh and exciting, this is popular history at its very best.

    The tiger isn’t just killing people, it’s annihilating them, and a team of men and their dogs must hunt it on foot through the forest in the brutal cold. As the trackers sift through the gruesome remains of the victims, they discover that these attacks aren’t random: the tiger is apparently engaged in a vendetta. Injured, starving, and extremely dangerous, the tiger must be found before it strikes again.As he re-creates these extraordinary events, John Vaillant gives us an unforgettable portrait of this spectacularly beautiful and mysterious region. We meet the native tribes who for centuries have worshipped and lived alongside tigers, even sharing their kills with them. We witness the arrival of Russian settlers in the nineteenth and early twentieth centuries, soldiers and hunters who greatly diminished the tiger populations. And we come to know their descendants, who, crushed by poverty, have turned to poaching and further upset the natural balance of the region.This ancient, tenuous relationship between man and predator is at the very heart of this remarkable book. Throughout we encounter surprising theories of how humans and tigers may have evolved to coexist, how we may have developed as scavengers rather than hunters, and how early Homo sapiens may have fit seamlessly into the tiger’s ecosystem. Above all, we come to understand the endangered Siberian tiger, a highly intelligent super-predator that can grow to ten feet long, weigh more than six hundred pounds, and range daily over vast territories of forest and mountain.Beautifully written and deeply informative, The Tiger circles around three main characters: Vladimir Markov, a poacher killed by the tiger; Yuri Trush, the lead tracker; and the tiger himself. It is an absolutely gripping tale of man and nature that leads inexorably to a final showdown in a clearing deep in the taiga.

    Thousands of fans flocked to multi‑day events, and cities vied with one another to host them. The pilots themselves were hailed as dashing heroes who cheerfully stared death in the face. Well, the men were hailed. Female pilots were more often ridiculed than praised for what the press portrayed as silly efforts to horn in on a manly, and deadly, pursuit. Fly Girls recounts how a cadre of women banded together to break the original glass ceiling: the entrenched prejudice that conspired to keep them out of the sky. O’Brien weaves together the stories of five remarkable women: Florence Klingensmith, a high‑school dropout who worked for a dry cleaner in Fargo, North Dakota; Ruth Elder, an Alabama divorcee; Amelia Earhart, the most famous, but not necessarily the most skilled; Ruth Nichols, who chafed at the constraints of her blue‑blood family’s expectations; and Louise Thaden, the mother of two young kids who got her start selling coal in Wichita. Together, they fought for the chance to race against the men — and in 1936 one of them would triumph in the toughest race of all.   Like Hidden Figures and Girls of Atomic City, Fly Girls celebrates a little-known slice of history in which tenacious, trail-blazing women braved all obstacles to achieve greatness.

    In July he finds it while taking a dip in a 35-degree Arctic swimming hole; in September while excavating our planet's ancient and not so ancient ice ages; and in October while exploring hibernation habits in animals, from humans to wood frogs to bears.A scientist whose passion for cold runs red hot, Streever is a wondrous guide: he conjures woolly mammoth carcasses and the ice-age Clovis tribe from melting glaciers, and he evokes blizzards so wild readers may freeze--limb by vicarious limb.
