Nearly a half-century after Neil Armstrong walked on the moon, these Space Barons-most notably Elon Musk and Jeff Bezos, along with Richard Branson and Paul Allen-are using Silicon Valley-style innovation to dramatically lower the cost of space travel, and send humans even further than NASA has gone. These entrepreneurs have founded some of the biggest brands in the world-Amazon, Microsoft, Virgin, Tesla, PayPal-and upended industry after industry. Now they are pursuing the biggest disruption of all: space. Based on years of reporting and exclusive interviews with all four billionaires, this authoritative account is a dramatic tale of risk and high adventure, the birth of a new Space Age, fueled by some of the world's richest men as they struggle to end governments' monopoly on the cosmos. The Space Barons is also a story of rivalry-hard-charging startups warring with established contractors, and the personal clashes of the leaders of this new space movement, particularly Musk and Bezos, as they aim for the moon and Mars and beyond.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    Global warming and associated climate change exists - but the role of humans in that change is entirely debatable. A little-known aspect of modern climate science is that the warming of the global atmosphere-ocean system over the last 100 years, even if entirely human-caused, has progressed at a rate that reduces the threat of future warming by 50% compared to the climate model projections. To the extent warming is partly natural (a possibility even the IPCC acknowledges), the future threat is reduced even further. This, by itself, should be part of the debate over energy policy – but it isn’t. Why? The news media, politicians, bureaucrats, rent-seekers, government funding agencies, and a “scientific-technological elite” (as President Eisenhower called it) have collaborated to spread what amounts to fake climate news. Exaggerated climate claims appear on a daily basis, sucking the air out of more reasoned discussions of the scientific evidence which are too boring for a populace increasingly addicted to climate change porn. Upon close examination it is found that the "97% of climate scientists agree" meme is inaccurate, misleading, and useless for decision-making; human causation of warming is simply assumed by the vast majority of climate researchers. In contrast to what many have been taught, there have been no obvious changes in severe weather, including hurricanes, tornadoes, droughts or floods. Despite an active 2018 wildfire season, there has actually been a long-term decrease in wildfire activity, although that will change if forest management practices are not implemented. Proxy evidence of past temperature and Arctic sea ice changes suggest warming and sea ice decline over the last 50 years or so is not out of the ordinary, and partly or even mostly natural. The Antarctic ice sheet isn't collapsing, but remains stable. The human component of sea level rise is shown to be, at most, only 1 inch per 30 years (25% of the observed rate of rise); and the latest evidence is that more CO2 dissolved in ocean water will be good for marine life, not harmful. Admittedly, continued emissions of CO2 from fossil fuel burning can be expected to cause (and probably has caused) some of our recent warming. But the Paris Agreement, even if extended through the end of the 21st Century, will have no measurable effect on global temperatures because the governments of the world realize humanity will depend upon fossil fuels for decades to come. Despite news reports and politicians' proclamations, international agreements to reduce CO2 emissions are all economic pain for no observable climate gain. What government-mandated reliance on expensive and impractical energy sources will do is increase energy poverty, and poverty kills. This downside to illusory efforts to “Save the Earth” is already being experienced in the UK and elsewhere. If people are genuinely concerned about humanity thriving, they must reject global warming alarmism. In terms of environmental regulation, the end result of the U.S. EPA's Endangerment Finding will be reduced prosperity for all, and climate gain for none. The good news is that there is no global warming crisis, and this book will inform citizens and help guide governments toward decisions which benefit the most people while doing the least harm.

    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.

    In the 14 billion years since, scientists have pointed their telescopes upward, peering outward in space and backward in time, developing and refining theories to explain the weird and wonderful phenomena they observed.Through these observations, we now understand concepts like the size of the universe (still expanding), the distance to the next-nearest star from earth (Alpha Centauri, 26 trillion miles) and what drives the formation of elements (nuclear fusion), planets and galaxies (gravity), and black holes (gravitational collapse). But are these cosmological questions definitively answered or is there more to discover?Oxford University astrophysicist and popular YouTube personality Dr. Becky Smethurst presents everything you need to know about the universe in 10 accessible and engaging lessons.In Space at the Speed of Light: The History of 14 Billion Years for People Short on Time, she guides you through fundamental questions, both answered and unanswered, posed by space scientists. Why does gravity matter? How do we know the big bang happened? What is dark matter? Do aliens exist? Why is the sky dark at night? If you have ever looked up at night and wondered how it all works, you will find answers - and many more questions - in this pocket-sized tour of the universe!

    Buckminster Fuller is regarded as one of the most important figures of the 20th century, renowned for his achievements as an inventor, designer, architect, philosopher, mathematician, and dogged individualist. Perhaps best remembered for the Geodesic Dome and the term "Spaceship Earth," his work and his writings have had a profound impact on modern life and thought.Critical Path is Fuller's master work--the summing up of a lifetime's thought and concern--as urgent and relevant as it was upon its first publication in 1981. Critical Path details how humanity found itself in its current situation--at the limits of the planet's natural resources and facing political, economic, environmental, and ethical crises.The crowning achievement of an extraordinary career, Critical Path offers the reader the excitement of understanding the essential dilemmas of our time and how responsible citizens can rise to meet this ultimate challenge to our future.

    Yet today, science and its practitioners have come under political attack. In this fascinating history spanning continents and centuries, historian David Wootton offers a lively defense of science, revealing why the Scientific Revolution was truly the greatest event in our history.The Invention of Science goes back five hundred years in time to chronicle this crucial transformation, exploring the factors that led to its birth and the people who made it happen. Wootton argues that the Scientific Revolution was actually five separate yet concurrent events that developed independently, but came to intersect and create a new worldview. Here are the brilliant iconoclasts—Galileo, Copernicus, Brahe, Newton, and many more curious minds from across Europe—whose studies of the natural world challenged centuries of religious orthodoxy and ingrained superstition.From gunpowder technology, the discovery of the new world, movable type printing, perspective painting, and the telescope to the practice of conducting experiments, the laws of nature, and the concept of the fact, Wotton shows how these discoveries codified into a social construct and a system of knowledge. Ultimately, he makes clear the link between scientific discovery and the rise of industrialization—and the birth of the modern world we know.

    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.”

    Starting once again with fossils, he turns his gaze skyward, showing us how the entirety of the universe’s fourteen-billion-year history can be seen in our bodies. As he moves from our very molecular composition (a result of stellar events at the origin of our solar system) through the workings of our eyes, Shubin makes clear how the evolution of the cosmos has profoundly marked our own bodies. Fully illustrated with black and white drawings.

    We want to speak up but fear we'll be seen as unwoke, or worse, labeled a racist. According to John McWhorter, the problem is that a well-meaning but pernicious form of antiracism has become, not a progressive ideology, but a religion--and one that's illogical, unreachable, and unintentionally neoracist.In Woke Racism, McWhorter reveals the workings of this new religion, from the original sin of "white privilege" and the weaponization of cancel culture to ban heretics, to the evangelical fervor of the "woke mob." He shows how this religion that claims to "dismantle racist structures" is actually harming his fellow Black Americans by infantilizing Black people, setting Black students up for failure, and passing policies that disproportionately damage Black communities. The new religion might be called "antiracism," but it features a racial essentialism that's barely distinguishable from racist arguments of the past.Fortunately for Black America, and for all of us, it's not too late to push back against woke racism. McWhorter shares scripts and encouragement with those trying to deprogram friends and family. And most importantly, he offers a roadmap to justice that actually will help, not hurt, Black America.

    A populist rebellion against the established churches, it became the dominant religious force in the country.During the nineteenth century white evangelicals split apart dramatically, first North versus South, and then at the end of the century, modernist versus fundamentalist. After World War II, Billy Graham, the revivalist preacher, attracted enormous crowds and tried to gather all Protestants under his big tent, but the civil rights movement and the social revolution of the sixties drove them apart again. By the 1980s Jerry Falwell and other southern televangelists, such as Pat Robertson, had formed the Christian right. Protesting abortion and gay rights, they led the South into the Republican Party, and for thirty-five years they were the sole voice of evangelicals to be heard nationally. Eventually a younger generation of leaders protested the Christian right’s close ties with the Republican Party and proposed a broader agenda of issues, such as climate change, gender equality, and immigration reform.Evangelicals have in many ways defined the nation. They have shaped our culture and our politics. Frances FitzGerald’s narrative of this distinctively American movement is a major work of history, piecing together the centuries-long story for the first time. Evangelicals now constitute twenty-five percent of the American population, but they are no longer monolithic in their politics. They range from Tea Party supporters to social reformers. Still, with the decline of religious faith generally, FitzGerald suggests that evangelical churches must embrace ethnic minorities if they are to survive.

    The challenge attracted more than one hundred teams from all over the world, including dozens of amateurs. Many designed their cars entirely from scratch, rejecting decades of thinking about what a car should look like.      Jason Fagone follows four of those teams from the build stage to the final race and beyond—into a world in which destiny hangs on a low drag coefficient and a lug nut can be a beautiful talisman. The result is a gripping story of crazy collaboration, absurd risks, colossal hopes, and poignant losses. In an old pole barn in central Illinois, childhood sweethearts hack together an electric-powered dreamboat, using scavenged parts, forging their own steel, and burning through their life savings.  In Virginia, an impassioned entrepreneur and his hand-picked squad of speed freaks pool their imaginations and build a car so light that you can push it across the floor with your thumb. In West Philly, a group of disaffected high school students come into their own as they create a hybrid car with the engine of a Harley motorcycle. And in Southern California, the early favorite—a start-up backed by millions in venture capital—designs a car that looks like an alien egg.      Ingenious is a joyride. Fagone takes us into the garages and the minds of the inventors, capturing the fractious yet beautiful process of engineering a bespoke machine. Suspenseful and bighearted, this is the story of ordinary people risking failure, economic ruin, and ridicule to create something vital that Detroit had never pulled off. As the Illinois team wrote in chalk on the wall of their barn, "SOMEBODY HAS TO DO SOMETHING. THAT SOMEBODY IS US."

    P. Snow, in a now famous essay, wrote about the polarization of the "two cultures" -- literary intellectuals on the one hand, and scientists on the other. Although he hoped for the emergence of a "third culture" that would bridge the gap, it is only recently that science has changed the intellectual landscape. Brockman's thesis that science is emerging as the intellectual center of our society is brought to life vividly in The Third Culture, which weaves together the voices of some of today's most influential scientific figures, including: Stephen Jay Gould and Richard Dawkins on the implications of evolution Steven Pinker, Marvin Minsky, Daniel C. Dennett, and Roger Penrose on how the mind works Murray Gell-Mann and Stuart Kauffman on the new sciences of complexity The Third Culture is an honest picture of science in action. It is at once stimulating, challenging, and riveting.

    Digital technologies—with hardware, software, and networks at their core—will in the near future diagnose diseases more accurately than doctors can, apply enormous data sets to transform retailing, and accomplish many tasks once considered uniquely human.In The Second Machine Age MIT’s Erik Brynjolfsson and Andrew McAfee—two thinkers at the forefront of their field—reveal the forces driving the reinvention of our lives and our economy. As the full impact of digital technologies is felt, we will realize immense bounty in the form of dazzling personal technology, advanced infrastructure, and near-boundless access to the cultural items that enrich our lives.Amid this bounty will also be wrenching change. Professions of all kinds—from lawyers to truck drivers—will be forever upended. Companies will be forced to transform or die. Recent economic indicators reflect this shift: fewer people are working, and wages are falling even as productivity and profits soar.Drawing on years of research and up-to-the-minute trends, Brynjolfsson and McAfee identify the best strategies for survival and offer a new path to prosperity. These include revamping education so that it prepares people for the next economy instead of the last one, designing new collaborations that pair brute processing power with human ingenuity, and embracing policies that make sense in a radically transformed landscape.A fundamentally optimistic book, The Second Machine Age alters how we think about issues of technological, societal, and economic progress.

    John McKnight shows how competent communities have been invaded and colonized by professionalized services -- often with devastating results. Overwhelmed by these social services, the spirit of community falters: families collapse, schools fail, violence spreads, and medical systems spiral out of control. Instead of more or better services, the basis for resolving many of America's social problems is the community capacity of the local citizens.
