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.

    bataar bones he was impressed. The enormous skull and teeth betrayed the apex predators close relation to the storied Tyrannosaurus rex, the most famous animal that ever lived. Prokopi's obsession with fossils had begun decades earlier, when he was a Florida boy scouring for shark teeth and Ice Age remnants, and it had continued as he built a thriving business hunting, preparing, and selling specimens to avid collectors and private museums around the world. To scientists' fury and dismay, there was big money to be made in certain corners of the fossil trade. Prokopi didn't consider himself merely a businessman, though. He also thought of himself as a vital part of paleontology--as one of the lesser-known artistic links in bringing prehistoric creatures back to life--and saw nothing wrong with turning a profit in the process. Bone hunting was expensive, risky, controversial work, and he increasingly needed bigger "scores." By the time he acquired a largely complete skeleton of T. bataar and restored it in his workshop, he was highly leveraged and drawing quiet scorn from peers who worried that by bringing such a big, beautiful Mongolian dinosaur to market he would tarnish the entire trade. Presenting the skeleton for sale at a major auction house in New York City, he was relieved to see the bidding start at nearly $1 million---only to fall apart when the president of Mongolia unexpectedly stepped in to question the specimen's origins and demand its return. An international custody battle ensued, shining new light on the black market for dinosaur fossils, the angst of scientists who fear for their field, and the precarious political tensions in post-Communist Mongolia. The Prokopi case, unprecedented in American jurisprudence, continues to reverberate throughout the intersecting worlds of paleontology, museums, art, and geopolitics.

    This man was a freediver, and his amphibious abilities inspired Nestor to seek out the secrets of this little-known discipline. In Deep, Nestor embeds with a gang of extreme athletes and renegade researchers who are transforming not only our knowledge of the planet and its creatures, but also our understanding of the human body and mind. Along the way, he takes us from the surface to the Atlantic’s greatest depths, some 28,000 feet below sea level. He finds whales that communicate with other whales hundreds of miles away, sharks that swim in unerringly straight lines through pitch-black waters, and seals who dive to depths below 2,400 feet for up to eighty minutes—deeper and longer than scientists ever thought possible. As strange as these phenomena are, they are reflections of our own species’ remarkable, and often hidden, potential—including echolocation, directional sense, and the profound physiological changes we undergo when underwater. Most illuminating of all, Nestor unlocks his own freediving skills as he communes with the pioneers who are expanding our definition of what is possible in the natural world, and in ourselves.

    Can our world support that? What kind of world will it be? Those answering these questions generally fall into two deeply divided groups--Wizards and Prophets, as Charles Mann calls them in this balanced, authoritative, nonpolemical new book. The Prophets, he explains, follow William Vogt, a founding environmentalist who believed that in using more than our planet has to give, our prosperity will lead us to ruin. Cut back! was his mantra. Otherwise everyone will lose! The Wizards are the heirs of Norman Borlaug, whose research, in effect, wrangled the world in service to our species to produce modern high-yield crops that then saved millions from starvation. Innovate! was Borlaug's cry. Only in that way can everyone win! Mann delves into these diverging viewpoints to assess the four great challenges humanity faces--food, water, energy, climate change--grounding each in historical context and weighing the options for the future. With our civilization on the line, the author's insightful analysis is an essential addition to the urgent conversation about how our children will fare on an increasingly crowded Earth.

    Stringer's new theory, based on archeological and genetic evidence, holds that distinct humans coexisted and competed across the African continent—exchanging genes, tools, and behavioral strategies.Stringer draws on analyses of old and new fossils from around the world, DNA studies of Neanderthals (using the full genome map) and other species, and recent archeological digs to unveil his new theory. He shows how the most sensational recent fossil findings fit with his model, and he questions previous concepts (including his own) of modernity and how it evolved.Lone Survivors will be the definitive account of who and what we were, and will change perceptions about our origins and about what it means to be human.

    Since the age of six, when Orlean wrote and illustrated a book called Herbert the Near-Sighted Pigeon, she’s been drawn to stories about how we live with animals, and how they abide by us. Now, in On Animals, she examines animal-human relationships through the compelling tales she has written over the course of her celebrated career.These stories consider a range of creatures—the household pets we dote on, the animals we raise to end up as meat on our plates, the creatures who could eat us for dinner, the various tamed and untamed animals we share our planet with who are central to human life. In her own backyard, Orlean discovers the delights of keeping chickens. In a different backyard, in New Jersey, she meets a woman who has twenty-three pet tigers—something none of her neighbors knew about until one of the tigers escapes. In Iceland, the world’s most famous whale resists the efforts to set him free; in Morocco, the world’s hardest-working donkeys find respite at a special clinic. We meet a show dog and a lost dog and a pigeon who knows exactly how to get home.Equal parts delightful and profound, enriched by Orlean’s stylish prose and precise research, these stories celebrate the meaningful cross-species connections that grace our collective existence.

    Its geology, its unique flora and fauna, and its striking role in human history intersect in surprising and dynamic ways. This book is the most wide-ranging and beautifully illustrated book available on the famous islands. Not since Darwin’s Naturalist’s Voyage has a book combined so much scientific and historic information with firsthand accounts that bring the Galápagos to life.Galápagos: The Islands That Changed the World describes how tragedy and murderous pirates curtailed settlement of the islands and how the islands’ pristine nature, spectacular geology, and defining isolation inspired Darwin’s ideas about evolution. The book explores the diverse land and marine habitats that shelter Galápagos species and considers the islands’ importance today as a frontier for science and a refuge for true wilderness. The book’s extensive gazetteer provides details about endemic plants and animals as well as travel advice about visitors’ sites, diving, photography, when to go, and what to take. Vividly illustrated throughout, this guide is an indispensable reference for natural history enthusiasts, armchair travelers, and island visitors alike.

    Every concrete building and paved road on Earth, every computer screen and silicon chip, is made from sand. From Egypt's pyramids to the Hubble telescope, from the world's tallest skyscraper to the sidewalk below it, from Chartres' stained-glass windows to your iPhone, sand shelters us, empowers us, engages us, and inspires us. It's the ingredient that makes possible our cities, our science, our lives--and our future.And, incredibly, we're running out of it.The World in a Grain is the compelling true story of the hugely important and diminishing natural resource that grows more essential every day, and of the people who mine it, sell it, build with it--and sometimes, even kill for it. It's also a provocative examination of the serious human and environmental costs incurred by our dependence on sand, which has received little public attention. Not all sand is created equal: Some of the easiest sand to get to is the least useful. Award-winning journalist Vince Beiser delves deep into this world, taking readers on a journey across the globe, from the United States to remote corners of India, China, and Dubai to explain why sand is so crucial to modern life. Along the way, readers encounter world-changing innovators, island-building entrepreneurs, desert fighters, and murderous sand pirates. The result is an entertaining and eye-opening work, one that is both unexpected and involving, rippling with fascinating detail and filled with surprising characters.

    As the pandemic unfolded, Gottlieb was in regular contact with all the key players in Congress, the Trump administration, and the drug and diagnostic industries. He provides an inside account of how level after level of American government crumbled as the COVID-19 crisis advanced.A system-wide failure across government institutions left the nation blind to the threat, and unable to mount an effective response. We’d prepared for the wrong virus. We failed to identify the contagion early enough and became overly reliant on costly and sometimes divisive tactics that couldn’t fully slow the spread. We never considered asymptomatic transmission and we assumed people would follow public health guidance. Key bureaucracies like the CDC were hidebound and outmatched. Weak political leadership aggravated these woes. We didn’t view a public health disaster as a threat to our national security.Many of the woes sprung from the CDC, which has very little real-time reporting capability to inform us of Covid’s twists and turns or assess our defenses. The agency lacked an operational capacity and mindset to mobilize the kind of national response that was needed. To guard against future pandemic risks, we must remake the CDC and properly equip it to better confront crises. We must also get our intelligence services more engaged in the global public health mission, to gather information and uncover emerging risks before they hit our shores so we can head them off. For this role, our clandestine agencies have tools and capabilities that the CDC lacks.Uncontrolled Spread argues we must fix our systems and prepare for a deadlier coronavirus variant, a flu pandemic, or whatever else nature -- or those wishing us harm -- may threaten us with. Gottlieb outlines policies and investments that are essential to prepare the United States and the world for future threats.

    In What Is Life?, he takes up the challenge of describing what it means to be alive in a way that every reader can understand.It is a shared journey of discovery; step-by-step Nurse illuminates five great ideas that underpin biology—the Cell, the Gene, Evolution by Natural Selection, Life as Chemistry, and Life as Information. He introduces the scientists who made the most important advances, and, using his personal experiences in and out of the lab, he shares with us the challenges, the lucky breaks, and the thrilling eureka moments of discovery.Nurse writes with delight at life’s richness and with a sense of the urgent role of biology in our time. To survive the challenges that face us all today—climate change, pandemic, loss of biodiversity and food security—it is vital that we all understand what life is.

    Ultimately, the history of these challenges tells the story of humanity itself. Through an unforgettable cast of characters, Pulitzer Prize-winning author Richard Rhodes explains how wood gave way to coal and coal made room for oil, as we now turn to natural gas, nuclear power, and renewable energy. Rhodes looks back on five centuries of progress, through such influential figures as Queen Elizabeth I, King James I, Benjamin Franklin, Herman Melville, John D. Rockefeller, and Henry Ford. In Energy, Rhodes highlights the successes and failures that led to each breakthrough in energy production; from animal and waterpower to the steam engine, from internal-combustion to the electric motor. He addresses how we learned from such challenges, mastered their transitions, and capitalized on their opportunities. Rhodes also looks at the current energy landscape, with a focus on how wind energy is competing for dominance with cast supplies of coal and natural gas. He also addresses the specter of global warming, and a population hurtling towards ten billion by 2100. Human beings have confronted the problem of how to draw life from raw material since the beginning of time. Each invention, each discovery, each adaptation brought further challenges, and through such transformations, we arrived at where we are today. In Rhodes’s singular style, Energy details how this knowledge of our history can inform our way tomorrow.

    This is the history of how England's elite came to own our land, and an inspiring manifesto for how to open up our countryside once more. This book has been a long time coming. Since 1086, in fact. For centuries, England's elite have covered up how they got their hands on millions of acres of our land, by constructing walls, burying surveys and more recently, sheltering behind offshore shell companies. But with the dawn of digital mapping and the Freedom of Information Act, it's becoming increasingly difficult for them to hide.Trespassing through tightly-guarded country estates, ecologically ravaged grouse moors and empty Mayfair mansions, writer and activist Guy Shrubsole has used these 21st century tools to uncover a wealth of never-before-seen information about the people who own our land, to create the most comprehensive map of land ownership in England that has ever been made public.From secret military islands to tunnels deep beneath London, Shrubsole unearths truths concealed since the Domesday Book about who is really in charge of this country - at a time when Brexit is meant to be returning sovereignty to the people. Melding history, politics and polemic, he vividly demonstrates how taking control of land ownership is key to tackling everything from the housing crisis to climate change - and even halting the erosion of our very democracy.It's time to expose the truth about who owns England - and finally take back our green and pleasant land.

    From the thawing tundra linking a Yup'ik village in Alaska to its hunter-gatherer past to the shifting sand dunes revealing the impressively preserved homes of neolithic farmers in Scotland, Jamie explores how the changing natural world can alter our sense of time. Most movingly, she considers, as her father dies and her children leave home, the surfacing of an older, less tethered sense of herself. In precise, luminous prose, Surfacing offers a profound sense of time passing and an antidote to all that is instant, ephemeral, unrooted.

    Sixty-six million years ago, the Earth’s most fearsome creatures vanished. Today they remain one of our planet’s great mysteries. Now The Rise and Fall of the Dinosaurs reveals their extraordinary, 200-million-year-long story as never before.In this captivating narrative (enlivened with more than seventy original illustrations and photographs), Steve Brusatte, a young American paleontologist who has emerged as one of the foremost stars of the field—naming fifteen new species and leading groundbreaking scientific studies and fieldwork—masterfully tells the complete, surprising, and new history of the dinosaurs, drawing on cutting-edge science to dramatically bring to life their lost world and illuminate their enigmatic origins, spectacular flourishing, astonishing diversity, cataclysmic extinction, and startling living legacy. Captivating and revelatory, The Rise and Fall of the Dinosaurs is a book for the ages.Brusatte traces the evolution of dinosaurs from their inauspicious start as small shadow dwellers—themselves the beneficiaries of a mass extinction caused by volcanic eruptions at the beginning of the Triassic period—into the dominant array of species every wide-eyed child memorizes today, T. rex, Triceratops, Brontosaurus, and more. This gifted scientist and writer re-creates the dinosaurs’ peak during the Jurassic and Cretaceous, when thousands of species thrived, and winged and feathered dinosaurs, the prehistoric ancestors of modern birds, emerged. The story continues to the end of the Cretaceous period, when a giant asteroid or comet struck the planet and nearly every dinosaur species (but not all) died out, in the most extraordinary extinction event in earth’s history, one full of lessons for today as we confront a “sixth extinction.”Brusatte also recalls compelling stories from his globe-trotting expeditions during one of the most exciting eras in dinosaur research—which he calls “a new golden age of discovery”—and offers thrilling accounts of some of the remarkable findings he and his colleagues have made, including primitive human-sized tyrannosaurs; monstrous carnivores even larger than T. rex; and paradigm-shifting feathered raptors from China.An electrifying scientific history that unearths the dinosaurs’ epic saga, The Rise and Fall of the Dinosaurs will be a definitive and treasured account for decades to come.
