Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that Pluto was a planet. For decades, we were convinced that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing.   But it turns out there’s an order to the state of knowledge, an explanation for how we know what we know. Samuel Arbesman is an expert in the field of scientometrics—literally the science of science. Knowl­edge in most fields evolves systematically and predict­ably, and this evolution unfolds in a fascinating way that can have a powerful impact on our lives.   Doctors with a rough idea of when their knowl­edge is likely to expire can be better equipped to keep up with the latest research. Companies and govern­ments that understand how long new discoveries take to develop can improve decisions about allocating resources. And by tracing how and when language changes, each of us can better bridge gen­erational gaps in slang and dialect.   Just as we know that a chunk of uranium can break down in a measurable amount of time—a radioactive half-life—so too any given field’s change in knowledge can be measured concretely. We can know when facts in aggregate are obsolete, the rate at which new facts are created, and even how facts spread.   Arbesman takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries. He shows that much of what we know consists of “mesofacts”—facts that change at a middle timescale, often over a single human lifetime. Throughout, he of­fers intriguing examples about the face of knowledge: what English majors can learn from a statistical analysis of The Canterbury Tales, why it’s so hard to measure a mountain, and why so many parents still tell kids to eat their spinach because it’s rich in iron.   The Half-life of Facts is a riveting journey into the counterintuitive fabric of knowledge. It can help us find new ways to measure the world while accepting the limits of how much we can know with certainty.

    Presidents John F. Kennedy and Lyndon Johnson utilized the space program as an agent for social change, using federal equal employment opportunity laws to open workplaces at NASA and NASA contractors to African Americans while creating thousands of research and technology jobs in the Deep South to ameliorate poverty. 'We Could Not Fail' tells the inspiring, largely unknown story of how shooting for the stars helped to overcome segregation on earth.Richard Paul and Steven Moss profile 10 pioneer African American space workers whose stories illustrate the role NASA and the space program played in promoting civil rights. They recount how these technicians, mathematicians, engineers, and an astronaut candidate surmounted barriers to move, in some cases literally, from the cotton fields to the launching pad. The authors vividly describe what it was like to be the sole African American in a NASA work group and how these brave and determined men also helped to transform Southern society by integrating colleges, patenting new inventions, holding elective offices, as well as reviving and governing defunct towns. Adding new names to the roster of civil rights heroes and a new chapter to the story of space exploration, 'We Could Not Fail' demonstrates how African Americans broke the color barrier by competing successfully at the highest level of American intellectual and technological achievement.©2015 Richard Paul and Steven Moss (P)2019 Audible, Inc

    In 1905 an unknown 26-year-old clerk at the Swiss Patent Office, who had supposedly failed math in school, burst on to the scientific scene and swept away the hidebound theories of the day. The clerk, Albert Einstein, introduced a new and unexpected understanding of the universe and launched the two great revolutions of twentieth-century physics, relativity and quantum mechanics. The obscure origin and wide-ranging brilliance of the work recalled Isaac Newton’s “annus mirabilis” (miracle year) of 1666, when as a 23-year-old seeking safety at his family manor from an outbreak of the plague, he invented calculus and laid the foundations for his theory of gravity. Like Newton, Einstein quickly became a scientific icon--the image of genius and, according to Time magazine, the Person of the Century.The actual story is much more interesting. Einstein himself once remarked that “science as something coming into being ... is just as subjectively, psychologically conditioned as are all other human endeavors.” In this profile, the historian of science L. Randles Lagerstrom takes you behind the myth and into the very human life of the young Einstein. From family rifts and girlfriend troubles to financial hardships and jobless anxieties, Einstein’s early years were typical of many young persons. And yet in the midst of it all, he also saw his way through to profound scientific insights. Drawing upon correspondence from Einstein, his family, and his friends, Lagerstrom brings to life the young Einstein and enables the reader to come away with a fuller and more appreciative understanding of Einstein the person and the origins of his revolutionary ideas.About the cover image: While walking to work six days a week as a patent clerk in Bern, Switzerland, Einstein would pass by the famous "Zytglogge" tower and its astronomical clocks. The daily juxtaposition was fitting, as the relative nature of time and clock synchronization would be one of his revolutionary discoveries in the miracle year of 1905.

    Following the Industrial Revolution, civilized societies remade nineteenth-century capitalism into a more humane version of itself, and Keen shows how we can do the same in the wake of the Digital Revolution.As consensus builds around the importance of making sure the Internet remains a force for good, we need a road map of what actions we can take to ensure that the Internet works for us, and not the other way around. Keen identifies five broad strategies to tackle the digital future: competitive innovation, government regulation, consumer choice, social responsibility by business leaders, and education. Traveling the world in order to identify best (and worst) practices in these five areas, Keen moves from Estonia, where tech giants are forming a model for Internet governance, to Germany, whose automobile titans are navigating the future of self-driving cars, to Scandinavia, Korea, and, of course, Silicon Valley. Powerfully argued and deeply engaging, How to Fix the Future provides hope that the future may yet become something that we can look forward to.

    Chris O’Brien presents the case for beer as both the cause of and solution to all of the world’s problems. Beer has contributed to the best qualities of civilization, but it is also helping to destroy them.The global beer industry relies heavily on fossil-fuels and chemical agriculture, rapidly destroying nature and contributing to climate change.Corporate beer is centralized and hierarchical, which is good for a few elites, but displaces local brewing traditions and exacerbates the growing wealth gap.But the craft brewing renaissance relies on cooperation, emphasizes local production, protects and celebrates nature, and nurtures the growth of strong and equitable communities.Fermenting Revolution traces the path of brewing from a women-led, home-based craft to corporate industry, and describes how modern craft breweries and home-brewers are forging stronger communities. O’Brien explains how corporate mega-breweries are also taking steps to pioneer industrial ecology, and profiles the most inspiring and radical breweries, brewers, and beer drinkers that are making the world a better place to live.In the last two decades, Americans have returned to to beer as a way of life rather than as a commodity. Casting off its industrial chains, beer is again communal, convivial, democratic, healthful, and natural. The contemporary American brewing scene champions ecologically sustainable production and is helping to create thriving community places. After reading Fermenting Revolution, mere beer drinkers will become "beer activists," ready to fight corporate rule by simply meeting their neighbors for a pint at the local brewpub-saving the world one beer at a time.

    Not a master mason or carpenter, Filippo Brunelleschi was a goldsmith and clock maker. Over twenty-eight years, he would dedicate himself to solving puzzles of the dome's construction. In the process, he did nothing less than reinvent the field of architecture. He engineered the perfect placement of brick and stone (some among the most renowned machines of the Renaissance) to carry an estimated seventy million pounds hundreds of feet into the air, and designed the workers' platforms and routines so carefully that only one man died during the decades of construction. This drama was played out amid plagues, wars, political feuds, and the intellectual ferments of Renaissance Florence - events Ross King weaves into a story to great effect. An American Library Association Best Book of the Year Boston Globe: "An absorbing tale." Los Angeles Times: "Ross King has a knack for explaining complicated processes in a manner that is not only lucid but downright intriguing... Fascinating."

    But how many of us can afford such a spread without a crippling mortgage? If you can't make the hefty payments on your survival retreat, the bankers will evict you, leaving you worse off than those who failed to prepare in the first place. M.D. Creekmore's motivation for finding a low-cost retreat was the need to live on a lot less money after he lost his job and got divorced. He started living in a travel trailer, parked on two acres he'd bought a few years back to use as a campsite and bug-out location, never dreaming he'd be living there full time. But he has called his trailer home for the past four years and says that "for the first time in my life, I'm actually content." Living off the grid in a travel trailer isn't for everyone. But if you are looking for a way to own a debt-free home--and enjoy the security that comes with it--here's the author's dirt-cheap plan for finding suitable land; buying a used trailer; securing it against the elements and intruders; providing alternative power sources; dealing with water and waste issues; maximizing your space; and establishing a workable storage system for food, water, medicine, tools, and other equipment. The good news is that the author has done the hard part for you.

    Yet unless, or until, a misfit between our own body and the world is acute enough to be understood as disability, we may never stop to consider--or reconsider--the hidden assumptions on which our everyday environment is built.In a series of vivid stories drawn from the lived experience of disability and the ideas and innovations that have emerged from it--from cyborg arms to customizable cardboard chairs to deaf architecture--Sara Hendren invites us to rethink the things and settings we live with. What might assistance based on the body's stunning capacity for adaptation--rather than a rigid insistence on "normalcy"--look like? Can we foster interdependent, not just independent, living? How do we creatively engineer public spaces that allow us all to navigate our common terrain? By rendering familiar objects and environments newly strange and wondrous, What Can a Body Do? helps us imagine a future that will better meet the extraordinary range of our collective needs and desires.
