Why is glass see-through? What makes elastic stretchy? Why does a paper clip bend? Why does any material look and behave the way it does? These are the sorts of questions that Mark Miodownik a globally-renowned materials scientist has spent his life exploring In this book he examines the materials he encounters in a typical morning, from the steel in his razor and the graphite in his pencil to the foam in his sneakers and the concrete in a nearby skyscraper.

    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.

    Dozens of Top 10 lists - from Chicago's Top 10 skyscapers to the Top 10 places to eat, the best ethnic neighborhoods, jazz and blues joints, museums and events - lead you to the very best Chicago has to offer.

    Encompassing a grand sweep of human history, A History of the World in 100 Objects begins with one of the earliest surviving objects made by human hands, a chopping tool from the Olduvai gorge in Africa, and ends with objects which characterise the world we live in today. Seen through MacGregor's eyes, history is a kaleidoscope - shifting, interconnected, constantly surprising, and shaping our world today in ways that most of us have never imagined. A stone pillar tells us about a great Indian emperor preaching tolerance to his people; Spanish pieces of eight tell us about the beginning of a global currency; and an early Victorian tea-set speaks to us about the impact of empire. An intellectual and visual feast, this is one of the most engrossing and unusual history books published in years. 'Brilliant, engagingly written, deeply researched' Mary Beard, Guardian 'A triumph: hugely popular, and rightly lauded as one of the most effective and intellectually ambitious initiatives in the making of 'public history' for many decades' Sunday Telegraph 'Highly intelligent, delightfully written and utterly absorbing ' Timothy Clifford, Spectator 'This is a story book, vivid and witty, shining with insights, connections, shocks and delights' Gillian Reynolds Daily Telegraph

    There has never been a better time to be a geek (or a nerd, or a dork). What was once an insult used to marginalize those curious people (in either sense of the word) and their obsessive interest in science has increasingly become a badge of honor. And we should be crying out for them. England is a country where only one of 650 MPs has worked as a research scientist, the government's drug adviser was sacked for making a decision based on scientific fact rather than public opinion, a writer can be forced into court for telling the scientific truth, and the media would rather sell papers by scaremongering over MMR vaccines and GM crops than report the less sensational facts. Whether one wants to improve education, cut crime, enhance public health, or generate clean energy, science and its experimental method is critical. It's time to stop the nonsense! The Geek Manifesto explains what needs to happen to entrench scientific thinking more deeply into politics and society; and how those who are concerned can turn their frustrated outrage into positive action that our country's leaders cannot ignore. Contributors include Ben Goldacre, Simon Singh, Robin Ince, Evan Harris, Tim Harford, Brian Cox, and Sir Paul Nurse.

    One sought to discover a new planet. Another—an adventuresome female astronomer—fought to prove that science was not anathema to femininity. And a young, megalomaniacal inventor, with the tabloid press fast on his heels, sought to test his scientific bona fides and light the world through his revelations. David Baron brings to three-dimensional life these three competitors—James Craig Watson, Maria Mitchell, and Thomas Edison—and thrillingly re-creates the fierce jockeying of nineteenth-century American astronomy. With spellbinding accounts of train robberies and Indian skirmishes, the mythologized age of the last days of the Wild West comes alive as never before. A magnificent portrayal of America’s dawn as a scientific superpower, American Eclipse depicts a young nation that looked to the skies to reveal its towering ambition and expose its latent genius.

    Vesuvius, whose eruption in Roman times helped spark the science of geology, and ending in a lab in the West of England where mathematical models and lab experiments replace direct observation, Richard Fortey tells us what the present says about ancient geologic processes. He shows how plate tectonics came to rule the geophysical landscape and how the evidence is written in the hills and in the stones. And in the process, he takes us on a wonderful journey around the globe to visit some of the most fascinating and intriguing spots on the planet.

    That nation did not exist when, in the mid-19th century, Europeans first began to explore the possibilities of creating a link between the Atlantic and Pacific oceans through the narrow but mountainous isthmus; Panama was then a remote and overlooked part of Colombia.All that changed, writes David McCullough in his magisterial history of the Canal, in 1848, when prospectors struck gold in California. A wave of fortune seekers descended on Panama from Europe and the eastern United States, seeking quick passage on California-bound ships in the Pacific, and the Panama Railroad, built to serve that traffic, was soon the highest-priced stock listed on the New York Exchange. To build a 51-mile-long ship canal to replace that railroad seemed an easy matter to some investors. But, as McCullough notes, the construction project came to involve the efforts of thousands of workers from many nations over four decades; eventually those workers, laboring in oppressive heat in a vast malarial swamp, removed enough soil and rock to build a pyramid a mile high. In the early years, they toiled under the direction of French entrepreneur Ferdinand de Lesseps, who went bankrupt while pursuing his dream of extending France's empire in the Americas. The United States then entered the picture, with President Theodore Roosevelt orchestrating the purchase of the canal—but not before helping foment a revolution that removed Panama from Colombian rule and placed it squarely in the American camp.

    “I walk with a new spring in my step and I look at life through physics-colored eyes,” wrote one such fan. When Lewin’s lectures were made available online, he became an instant YouTube celebrity, and The New York Times declared, “Walter Lewin delivers his lectures with the panache of Julia Child bringing French cooking to amateurs and the zany theatricality of YouTube’s greatest hits.” For more than thirty years as a beloved professor at the Massachusetts Institute of Technology, Lewin honed his singular craft of making physics not only accessible but truly fun, whether putting his head in the path of a wrecking ball, supercharging himself with three hundred thousand volts of electricity, or demonstrating why the sky is blue and why clouds are white. Now, as Carl Sagan did for astronomy and Brian Green did for cosmology, Lewin takes readers on a marvelous journey in For the Love of Physics, opening our eyes as never before to the amazing beauty and power with which physics can reveal the hidden workings of the world all around us. “I introduce people to their own world,” writes Lewin, “the world they live in and are familiar with but don’t approach like a physicist—yet.” Could it be true that we are shorter standing up than lying down? Why can we snorkel no deeper than about one foot below the surface? Why are the colors of a rainbow always in the same order, and would it be possible to put our hand out and touch one? Whether introducing why the air smells so fresh after a lightning storm, why we briefly lose (and gain) weight when we ride in an elevator, or what the big bang would have sounded like had anyone existed to hear it, Lewin never ceases to surprise and delight with the extraordinary ability of physics to answer even the most elusive questions. Recounting his own exciting discoveries as a pioneer in the field of X-ray astronomy—arriving at MIT right at the start of an astonishing revolution in astronomy—he also brings to life the power of physics to reach into the vastness of space and unveil exotic uncharted territories, from the marvels of a supernova explosion in the Large Magellanic Cloud to the unseeable depths of black holes. “For me,” Lewin writes, “physics is a way of seeing—the spectacular and the mundane, the immense and the minute—as a beautiful, thrillingly interwoven whole.” His wonderfully inventive and vivid ways of introducing us to the revelations of physics impart to us a new appreciation of the remarkable beauty and intricate harmonies of the forces that govern our lives.

    Sacred ruins, grand hotels, wildlife preserves, hilltop villages, snack shacks, castles, festivals, reefs, restaurants, cathedrals, hidden islands, opera houses, museums, and more. Each entry tells exactly why it's essential to visit. Then come the nuts and bolts: addresses, websites, phone and fax numbers, best times to visit. Stop dreaming and get going.This hefty volume reminds vacationers that hot tourist spots are small percentage of what's worth seeing out there. A quick sampling: Venice's Cipriani Hotel; California's Monterey Peninsula; the Lewis and Clark Trail in Oregon; the Great Wall of China; Robert Louis Stevenson's home in Western Samoa; and the Alhambra in Andalusia, Spain. Veteran travel guide writer Schultz divides the book geographically, presenting a little less than a page on each location. Each entry lists exactly where to find the spot (e.g. Moorea is located "12 miles/19 km northwest of Tahiti; 10 minutes by air, 1 hour by boat") and when to go (e.g., if you want to check out The Complete Fly Fisher hotel in Montana, "May and Sept.-Oct. offer productive angling in a solitary setting"). This is an excellent resource for the intrepid traveler.Copyright 2003 Reed Business Information, Inc.

    Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives, and the increasing fortunes of nations, hung on a resolution.The scientific establishment of Europe—from Galileo to Sir Issac Newton—had mapped the heavens in both hemispheres in its certain pursuit of a celestial answer. In stark contrast, one man, John Harrison, dared to imagine a mechanical solution—a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is a dramatic human story of an epic scientific quest and Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clock-making, and opens a new window on our world.On its 10th anniversary, a gift edition of this classic book, with a forward by one of history's greatest explorers, and eight pages of color illustrations.

    He saw in it the rise and climax of values so dear to him that their subsequent drop into catastrophe (in the person of Socrates - Plato) was clearly foreshadowed as though these were events taking place in the theater.And so in this work, unpublished in his own day but written at the same time that his The Birth of Tragedy had so outraged the German professorate as to imperil his own academic career, his most deeply felt task was one of education. He wanted to present the culture of the Greeks as a paradigm to his young German contemporaries who might thus be persuaded to work toward a state of culture of their own; a state where Nietzsche found sorely missing.

    From Mary, Queen of Scots, trapped by her own code, to the Navajo Code Talkers who helped the Allies win World War II, to the incredible (and incredibly simple) logisitical breakthrough that made Internet commerce secure, The Code Book tells the story of the most powerful intellectual weapon ever known: secrecy.Throughout the text are clear technical and mathematical explanations, and portraits of the remarkable personalities who wrote and broke the world’s most difficult codes. Accessible, compelling, and remarkably far-reaching, this book will forever alter your view of history and what drives it. It will also make you wonder how private that e-mail you just sent really is.

    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.
