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.

    It repays us many times over to be good economists. Economic issues are active in our lives every day. However, when the subject of economics comes up in conversation or on the news, we can find ourselves longing for a more sophisticated understanding of the fundamentals of economics.36 lectures | 30 minutes each.

    Today, buffeted by one food fad after another, America is suffering from what can only be described as a national eating disorder. The omnivore's dilemma has returned with a vengeance, as the cornucopia of the modern American supermarket and fast-food outlet confronts us with a bewildering and treacherous food landscape. What's at stake in our eating choices is not only our own and our children's health, but the health of the environment that sustains life on earth.The Omnivore's Dilemma is a groundbreaking book in which one of America's most fascinating, original, and elegant writers turns his own omnivorous mind to the seemingly straightforward question of what we should have for dinner. The question has confronted us since man discovered fire, but, according to Michael Pollan, the bestselling author of The Botany of Desire, how we answer it today, ath the dawn of the twenty-first century, may well determine our very survival as a species. Should we eat a fast-food hamburger? Something organic? Or perhaps something we hunt, gather or grow ourselves?To find out, Pollan follows each of the food chains that sustain us—industrial food, organic or alternative food, and food we forage ourselves—from the source to a final meal, and in the process develops a definitive account of the American way of eating. His absorbing narrative takes us from Iowa cornfields to food laboratories, from feedlots and fast-food restaurants to organic farms and hunting grounds, always emphasizing our dynamic coevolutionary relationship with the handful of plant and animal species we depend on. Each time Pollan sits down to a meal, he deploys his unique blend of personal and investigative journalism to trace the origins of everything consumed, revealing what we unwittingly ingest and explaining how our taste for particular foods and flavors reflects our evolutionary inheritance.The surprising answers Pollan offers to the simple question posed by this book have profound political, economic, psychological, and even mortal implications for all of us. Ultimately, this is a book as much about visionary solutions as it is about problems, and Pollan contends that, when it comes to food, doing the right thing often turns out to be the tastiest thing an eater can do. Beautifully written and thrillingly argued, The Omnivore's Dilemma promises to change the way we think about the politics and pleasure of eating. For anyone who reads it, dinner will never again look, or taste, quite the same.

    MacNeill examines the surprising - and sometimes unsettling - answers to this most basic of human questions. The remarkable new field of evolutionary psychology takes a scientific approach to the evolution of human nature. Analyzing human behavior in relation to food, clothing, shelter, health care, and sex, Evolutionary Psychology proves an immensely stimulating exploration of human endeavor.

    But a growing number of experts are sounding a different kind of alarm. Rather than growing exponentially, they argue, the global population is headed for a steep decline.Throughout history, depopulation was the product of catastrophe: ice ages, plagues, the collapse of civilizations. This time, however, we're thinning ourselves deliberately, by choosing to have fewer babies than we need to replace ourselves. In much of the developed and developing world, that decline is already underway, as urbanization, women's empowerment, and waning religiosity lead to smaller and smaller families. In Empty Planet, Ibbitson and Bricker travel from South Florida to Sao Paulo, Seoul to Nairobi, Brussels to Delhi to Beijing, drawing on a wealth of research and firsthand reporting to illustrate the dramatic consequences of this population decline--and to show us why the rest of the developing world will soon join in.They find that a smaller global population will bring with it a number of benefits: fewer workers will command higher wages; good jobs will prompt innovation; the environment will improve; the risk of famine will wane; and falling birthrates in the developing world will bring greater affluence and autonomy for women. But enormous disruption lies ahead, too. We can already see the effects in Europe and parts of Asia, as ageing populations and worker shortages weaken the economy and impose crippling demands on healthcare and social security. The United States is well-positioned to successfully navigate these coming demographic shifts--that is, unless growing isolationism and anti-immigrant backlash lead us to close ourselves off just as openness becomes more critical to our survival than ever before.Rigorously researched and deeply compelling, Empty Planet offers a vision of a future that we can no longer prevent--but one that we can shape, if we choose.

    scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. Our scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers.Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly—some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it.Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

    Now Wright attempts something even more ambitious: explaining the direction of evolution and human history–and discerning where history will lead us next.In Nonzero: The Logic of Human Destiny, Wright asserts that, ever since the primordial ooze, life has followed a basic pattern. Organisms and human societies alike have grown more complex by mastering the challenges of internal cooperation. Wright's narrative ranges from fossilized bacteria to vampire bats, from stone-age villages to the World Trade Organization, uncovering such surprises as the benefits of barbarian hordes and the useful stability of feudalism. Here is history endowed with moral significance–a way of looking at our biological and cultural evolution that suggests, refreshingly, that human morality has improved over time, and that our instinct to discover meaning may itself serve a higher purpose. Insightful, witty, profound, Nonzero offers breathtaking implications for what we believe and how we adapt to technology's ongoing transformation of the world.From the Trade Paperback edition.

    This has always been the case, no matter how often that certainty has failed. Though no generation believes there’s nothing left to learn, every generation unconsciously assumes that what has already been defined and accepted is (probably) pretty close to how reality will be viewed in perpetuity. And then, of course, time passes. Ideas shift. Opinions invert. What once seemed reasonable eventually becomes absurd, replaced by modern perspectives that feel even more irrefutable and secure—until, of course, they don’t.But What If We’re Wrong? visualizes the contemporary world as it will appear to those who'll perceive it as the distant past. Chuck Klosterman asks questions that are profound in their simplicity: How certain are we about our understanding of gravity? How certain are we about our understanding of time? What will be the defining memory of rock music, five hundred years from today? How seriously should we view the content of our dreams? How seriously should we view the content of television? Are all sports destined for extinction? Is it possible that the greatest artist of our era is currently unknown (or—weirder still—widely known, but entirely disrespected)? Is it possible that we “overrate” democracy? And perhaps most disturbing, is it possible that we’ve reached the end of knowledge?Kinetically slingshotting through a broad spectrum of objective and subjective problems, But What If We’re Wrong? is built on interviews with a variety of creative thinkers—George Saunders, David Byrne, Jonathan Lethem, Kathryn Schulz, Neil deGrasse Tyson, Brian Greene, Junot Díaz, Amanda Petrusich, Ryan Adams, Nick Bostrom, Dan Carlin, and Richard Linklater, among others—interwoven with the type of high-wire humor and nontraditional analysis only Klosterman would dare to attempt. It’s a seemingly impossible achievement: a book about the things we cannot know, explained as if we did. It’s about how we live now, once “now” has become “then.”

    Even as they bring ease to our lives, these programs are stealing something essential from us.Drawing on psychological and neurological studies that underscore how tightly people’s happiness and satisfaction are tied to performing hard work in the real world, Carr reveals something we already suspect: shifting our attention to computer screens can leave us disengaged and discontented.From nineteenth-century textile mills to the cockpits of modern jets, from the frozen hunting grounds of Inuit tribes to the sterile landscapes of GPS maps, The Glass Cage explores the impact of automation from a deeply human perspective, examining the personal as well as the economic consequences of our growing dependence on computers.With a characteristic blend of history and philosophy, poetry and science, Carr takes us on a journey from the work and early theory of Adam Smith and Alfred North Whitehead to the latest research into human attention, memory, and happiness, culminating in a moving meditation on how we can use technology to expand the human experience.

    is the first deep-dive investigation of a hazardous and illicit industry that has created a worldwide epidemic, ravaging communities and overwhelming and confounding government agencies that are challenged to combat it. "A whole new crop of chemicals is radically changing the recreational drug landscape," writes Ben Westhoff. "These are known as Novel Psychoactive Substances (NPS) and they include replacements for known drugs like heroin, cocaine, ecstasy, and marijuana. They are synthetic, made in a laboratory, and are much more potent than traditional drugs"--and all-too-often tragically lethal. Drugs like fentanyl, K2, and Spice--and those with arcane acronyms like 25i-NBOMe-- were all originally conceived in legitimate laboratories for proper scientific and medicinal purposes. Their formulas were then hijacked and manufactured by rogue chemists, largely in China, who change their molecular structures to stay ahead of the law, making the drugs' effects impossible to predict. Westhoff has infiltrated this shadowy world, becoming the first journalist to report from inside an illicit Chinese fentanyls lab and providing startling and original reporting on how China's vast chemical industry operates, and how the Chinese government subsidizes it. He tracks down the little-known scientists who invented these drugs and inadvertently killed thousands, as well as a mysterious drug baron who turned the law upside down in his home country of New Zealand. Poignantly, Westhoff chronicles the lives of addicted users and dealers, families of victims, law enforcement officers, and underground drug awareness organizers in the U.S. and Europe. Together they represent the shocking and riveting full anatomy of a calamity we are just beginning to understand. From its depths, as Westhoff relates, are emerging new strategies that may provide essential long-term solutions to the drug crisis that has affected so many.

    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.

    Evicted transforms our understanding of poverty and economic exploitation while providing fresh ideas for solving one of 21st-century America's most devastating problems. Its unforgettable scenes of hope and loss remind us of the centrality of home, without which nothing else is possible.

    In Coming Apart, Charles Murray explores the formation of American classes that are different in kind from anything we have ever known, focusing on whites as a way of driving home the fact that the trends he describes do not break along lines of race or ethnicity. Drawing on five decades of statistics and research, Coming Apart demonstrates that a new upper class and a new lower class have diverged so far in core behaviors and values that they barely recognize their underlying American kinship—divergence that has nothing to do with income inequality and that has grown during good economic times and bad. The top and bottom of white America increasingly live in different cultures, Murray argues, with the powerful upper class living in enclaves surrounded by their own kind, ignorant about life in mainstream America, and the lower class suffering from erosions of family and community life that strike at the heart of the pursuit of happiness. That divergence puts the success of the American project at risk. The evidence in Coming Apart is about white America. Its message is about all of America.

    The term “complexity” can be misleading, however, because what makes West’s discoveries so beautiful is that he has found an underlying simplicity that unites the seemingly complex and diverse phenomena of living systems, including our bodies, our cities and our businesses. Fascinated by issues of aging and mortality, West applied the rigor of a physicist to the biological question of why we live as long as we do and no longer. The result was astonishing, and changed science, creating a new understanding of energy use and metabolism: West found that despite the riotous diversity in the sizes of mammals, they are all, to a large degree, scaled versions of each other. If you know the size of a mammal, you can use scaling laws to learn everything from how much food it eats per day, what its heart-rate is, how long it will take to mature, its lifespan, and so on. Furthermore, the efficiency of the mammal’s circulatory systems scales up precisely based on weight: if you compare a mouse, a human and an elephant on a logarithmic graph, you find with every doubling of average weight, a species gets 25% more efficient—and lives 25% longer. This speaks to everything from how long we can expect to live to how many hours of sleep we need. Fundamentally, he has proven, the issue has to do with the fractal geometry of the networks that supply energy and remove waste from the organism's body. West's work has been game-changing for biologists, but then he made the even bolder move of exploring his work's applicability to cities. Cities, too, are constellations of networks and laws of scalability relate with eerie precision to them. For every doubling in a city's size, the city needs 15% less road, electrical wire, and gas stations to support the same population. More amazingly, for every doubling in size, cities produce 15% more patents and more wealth, as well as 15% more crime and disease. This broad pattern lays the groundwork for a new science of cities. Recently, West has applied his revolutionary work on cities and biological life to the business world. This investigation has led to powerful insights into why some companies thrive while others fail. The implications of these discoveries are far-reaching, and are just beginning to be explored. Scale is a thrilling scientific adventure story about the elemental natural laws that bind us together in simple but profound ways. Through the brilliant mind of Geoffrey West, we can envision how cities, companies and biological life alike are dancing to the same simple, powerful tune, however diverse and unrelated they are to each other.From the Hardcover edition.

    Friedman shows that we have entered an age of dizzying acceleration--and explains how to live in it. Due to an exponential increase in computing power, climbers atop Mount Everest enjoy excellent cell-phone service and self-driving cars are taking to the roads. A parallel explosion of economic interdependency has created new riches as well as spiraling debt burdens. Meanwhile, Mother Nature is also seeing dramatic changes as carbon levels rise and species go extinct, with compounding results.How do these changes interact, and how can we cope with them? To get a better purchase on the present, Friedman returns to his Minnesota childhood and sketches a world where politics worked and joining the middle class was an achievable goal. Today, by contrast, it is easier than ever to be a maker (try 3-D printing) or a breaker (the Islamic State excels at using Twitter), but harder than ever to be a leader or merely "average." Friedman concludes that nations and individuals must learn to be fast (innovative and quick to adapt), fair (prepared to help the casualties of change), and slow (adept at shutting out the noise and accessing their deepest values). With vision, authority, and wit, Thank You for Being Late establishes a blueprint for how to think about our times.
