And in this bold 24-lecture series, you can do just that.

    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.

    893 Western civilization is closely associated with reason and science, and with exceptional accomplishment in art, architecture, music, and literature. Yet it has also been characterized by widespread belief in the supernatural and the irrationalwith mystics who have visions of the divine, and with entire movements of people who wait in fervent anticipation of the apocalypse. In addition, Western culture has been the setting for repeated acts of barbarism: persecutions of certain groups such as Jews, or accused heretics and witches. Why has this been the case? This two-part series invites you to consider what might be called the "underbelly" of Western society, a complex mixture of deeply embedded beliefs and unsettling social forces that has given rise to our greatest saints and our most shameful acts. The "terror of history," according to Professor Teofilo F. Ruiz, is a deeply held beliefdating from the ancient Greeks to Nietzsche and beyondthat the world is essentially about disorder and emptiness, and that human beings live constantly on the edge of doom. We see history as terrifying, so we try to escape it. One strategy is to withdraw through transcendental experiences. Another, unfortunately, is to shift our fears onto scapegoats such as lepers, nonconformists, and other outsiders whom we choose to blame for "the catastrophe of our existence," as Professor Ruiz puts it.

    Most of the time this math works quietly behind the scenes . . . until it doesn't. All sorts of seemingly innocuous mathematical mistakes can have significant consequences.Math is easy to ignore until a misplaced decimal point upends the stock market, a unit conversion error causes a plane to crash, or someone divides by zero and stalls a battleship in the middle of the ocean.Exploring and explaining a litany of glitches, near misses, and mathematical mishaps involving the internet, big data, elections, street signs, lotteries, the Roman Empire, and an Olympic team, Matt Parker uncovers the bizarre ways math trips us up, and what this reveals about its essential place in our world. Getting it wrong has never been more fun.

    John Snow. It's the summer of 1854, and London is just emerging as one of the first modern cities in the world. But lacking the infrastructure—garbage removal, clean water, sewers—necessary to support its rapidly expanding population, the city has become the perfect breeding ground for a terrifying disease no one knows how to cure. As the cholera outbreak takes hold, a physician and a local curate are spurred to action—and ultimately solve the most pressing medical riddle of their time. In a triumph of multidisciplinary thinking, Johnson illuminates the intertwined histories and inter-connectedness of the spread of disease, contagion theory, the rise of cities, and the nature of scientific inquiry, offering both a riveting history and a powerful explanation of how it has shaped the world we live in.

    Study these crucibles of history to gain a better understanding of why a civilization took - or didn't take - a particular path. Full of dramatic reversals of fortune and colorful characters, this course examines some of the world's most notable examples of military misfortune, from the humiliating destruction of a Roman army at Carrhae in 53 BC to the tragic landings at Gallipoli in World War I. Success and failure, as you'll learn, are two sides of the same coin.These 24 lectures reveal how the trajectory of history hangs in the balance of individual battles; even a single person's actions in a particular moment have made drastic and irreversible impacts. From ancient Greece through global war during the first half of the 20th century, you'll delve into infamous conflicts such as the Charge of the Light Brigade and the Battle of Little Bighorn as well as lesser-known battles.How could an army equipped with cannon be wiped out by Zulu warriors wielding spears and outdated firearms? How could armored French knights be vulnerable to the crude weapons of a band of Flemish shopkeepers? Why would a savvy Chinese general fall victim to a tactic he had previously used himself? Unpredictable twists of fate abound, demonstrating that when it comes to war, there are no givens. Sheer numbers, superior weaponry, and skilled leadership are never a guarantee of success.Take a fascinating journey through some of the most gloriously inglorious wartime encounters. Along the way, you'll get to know some of the most legendary characters in world history.

    He looks at the difficult dialogue between science and religion; the conflict between our human desire for permanence and the impermanence of nature; the possibility that our universe is simply an accident; the manner in which modern technology has separated us from direct experience of the world; and our resistance to the view that our bodies and minds can be explained by scientific logic and laws. And behind all of these considerations is the suggestion—at once haunting and exhilarating—that what we see and understand of the world is only a tiny piece of the extraordinary, perhaps unfathomable whole.

    History at its most interesting is complex, a fascinating whirl of events, personalities, and forces, and few periods of history offer us such captivating complexity as Europe's 19th "century"—the often-broadly defined period from the French Revolution to World War I that formed the foundation of the modern world.How was that foundation built? And what did that transition to modernity mean for peasants, workers, the middle class, aristocrats, women, and minorities?Why did an era that began with the idealism of the French Revolution and the power of the Industrial Revolution culminate in the chaos of World War I, considered by most historians to be the greatest tragedy of modern European history? Did nationalism and imperialism inevitably lead in such a direction, or were there other factors involved?Even these questions, as important as they are, can only hint at the complexity of this period, just as this course can really only put us on a path toward the answers.

    November 2015 is the 100th anniversary of Einstein’s discovery of the General Theory of Relativity.Levenson, head of MIT’s Science Writing Program, tells the captivating, unusual, and nearly-forgotten backstory behind Einstein’s invention of the Theory of Relativity, which completely changed the course of science forever. For over 50 years before Einstein developed his theory, the world’s top astronomers spent countless hours and energy searching for a planet, which came to be named Vulcan, that had to exist, it was thought, given Isaac Newton’s theories of gravity. Indeed, in the two centuries since Newton’s death, his theory had essentially become accepted as fact. It took Einstein’s genius to realize the mystery of the missing planet wasn’t a problem of measurements or math but of Newton’s theory of gravity itself. Einstein’s Theory of Relativity proved that Vulcan did not and could not exist, and that the decades-long search for it had merely been a quirk of operating under the wrong set of assumptions about the universe. Thomas Levenson tells this unique story, one of the strangest episodes in the history of science, with elegant simplicity, fast-paced drama, and lively characters sure to capture the attention of a wide group of readers.

    The components of language are explained in easy-to-understand terms and the progression of the language from Germanic to Old, Middle, and Modern English is fully illustrated—including such revolutionary language upheavals as those brought about by the Norman Conquest and the Great Vowel Shift. One of the most interesting aspects of the English language lies in its variants, such as the “soda” vs. “pop” debate and the place of African-American English in modern culture. These and other dialectual curiosities are looked at in detail and placed in the context of today’s world. Finally, Professor Drout examines the future not only of the English language, but of all the world’s languages.

    But the president insisted there was nothing to worry about.Fortunately, we are still a nation of skeptics. Fortunately, there are those among us who study pandemics and are willing to look unflinchingly at worst-case scenarios. Michael Lewis’s taut and brilliant nonfiction thriller pits a band of medical visionaries against the wall of ignorance that was the official response of the Trump administration to the outbreak of COVID-19.The characters you will meet in these pages are as fascinating as they are unexpected. A thirteen-year-old girl’s science project on transmission of an airborne pathogen develops into a very grown-up model of disease control. A local public-health officer uses her worm’s-eye view to see what the CDC misses, and reveals great truths about American society. A secret team of dissenting doctors, nicknamed the Wolverines, has everything necessary to fight the pandemic: brilliant backgrounds, world-class labs, prior experience with the pandemic scares of bird flu and swine flu…everything, that is, except official permission to implement their work.Michael Lewis is not shy about calling these people heroes for their refusal to follow directives that they know to be based on misinformation and bad science. Even the internet, as crucial as it is to their exchange of ideas, poses a risk to them. They never know for sure who else might be listening in.
