    It was to last five years and transform him from an amiable and somewhat aimless young man into a scientific celebrity. Even more vitally, it was to set in motion the intellectual currents that culminated in the arrival of The Origin of Species in Victorian drawing-rooms in 1859. His journal, reprinted here in a shortened version, is vivid and immediate, showing us a naturalist making patient observations, above all in geology. As well as a profusion of natural history detail, it records many other things that caught Darwin’s eye, from civil war in Argentina to the new colonial settlements of Australia. The editors have provided an excellent introduction and notes for this Penguin Classics edition, which also contains maps and appendices, including an essay on scientific geology and the Bible by Robert FitzRoy, Darwin’s friend and captain of the Beagle.

    He argues that the only feasible explanations of scientific successes are historical explanations, and that anarchism must now replace rationalism in the theory of knowledge.

    The Klondike stampede was a wild interlude in the epic story of western development, and here are its dramatic tales of hardship, heroism, and villainy. We meet Soapy Smith, dictator of Skagway; Swiftwater Bill Gates, who bathed in champagne; Silent Sam Bonnifield, who lost and won back a hotel in a poker game; and Roddy Connors, who danced away a fortune at a dollar a dance. We meet dance-hall queens, paupers turned millionaires, missionaries and entrepreneurs, and legendary Mounties such as Sam Steele, the Lion of the Yukon.Pierre Berton's riveting account reveals to us the spectacle of the Chilkoot Pass, and the terrors of lesser-known trails through the swamps of British Columbia, across the glaciers of souther Alaska, and up the icy streams of the Mackenzie Mountains. It contrasts the lawless frontier life on the American side of the border to the relative safety of Dawson City. Winner of the Governor General's award for non-fiction, Klondike is authentic history and grand entertainment, and a must-read for anyone interested in the Canadian frontier.

    In The Alchemy of Us, scientist and science writer Ainissa Ramirez examines eight inventions--clocks, steel rails, copper communication cables, photographic film, light bulbs, hard disks, scientific labware, and silicon chips--and reveals how they shaped the human experience. Ramirez tells the stories of the woman who sold time, the inventor who inspired Edison, and the hotheaded undertaker whose invention pointed the way to the computer. She describes, among other things, how our pursuit of precision in timepieces changed how we sleep; how the railroad helped commercialize Christmas; how the necessary brevity of the telegram influenced Hemingway's writing style; and how a young chemist exposed the use of Polaroid's cameras to create passbooks to track black citizens in apartheid South Africa. These fascinating and inspiring stories offer new perspectives on our relationships with technologies.Ramirez shows how materials were shaped by inventors, but also how those materials shaped culture, chronicling each invention and its consequences--intended and unintended. Filling in the gaps left by other books about technology, Ramirez showcases little-known inventors--particularly people of color and women--who had a significant impact but whose accomplishments have been hidden by mythmaking, bias, and convention. Doing so, she shows us the power of telling inclusive stories about technology. She also shows that innovation is universal--whether it's splicing beats with two turntables and a microphone or splicing genes with two test tubes and CRISPR.

    At a summer tea party in Cambridge, England, a guest states that tea poured into milk tastes different from milk poured into tea. Her notion is shouted down by the scientific minds of the group. But one man, Ronald Fisher, proposes to scientifically test the hypothesis. There is no better person to conduct such an experiment, for Fisher is a pioneer in the field of statistics.The Lady Tasting Tea spotlights not only Fisher's theories but also the revolutionary ideas of dozens of men and women which affect our modern everyday lives. Writing with verve and wit, David Salsburg traces breakthroughs ranging from the rise and fall of Karl Pearson's theories to the methods of quality control that rebuilt postwar Japan's economy, including a pivotal early study on the capacity of a small beer cask at the Guinness brewing factory. Brimming with intriguing tidbits and colorful characters, The Lady Tasting Tea salutes the spirit of those who dared to look at the world in a new way.

    The story of information begins in a time profoundly unlike our own, when every thought and utterance vanishes as soon as it is born. From the invention of scripts and alphabets to the long-misunderstood talking drums of Africa, Gleick tells the story of information technologies that changed the very nature of human consciousness. He provides portraits of the key figures contributing to the inexorable development of our modern understanding of information: Charles Babbage, the idiosyncratic inventor of the first great mechanical computer; Ada Byron, the brilliant and doomed daughter of the poet, who became the first true programmer; pivotal figures like Samuel Morse and Alan Turing; and Claude Shannon, the creator of information theory itself. And then the information age arrives. Citizens of this world become experts willy-nilly: aficionados of bits and bytes. And we sometimes feel we are drowning, swept by a deluge of signs and signals, news and images, blogs and tweets. The Information is the story of how we got here and where we are heading.

    Their "Lunar Society" included Joseph Priestley, the chemist who isolated oxygen; James Watt, the Scottish inventor of the steam engine; and Josiah Wedgwood, whose manufacture of pottery created the industrial model for the next century. Joined by other "toymakers" and scholarly tinkerers, they concocted schemes for building great canals and harnessing the power of electricity, coined words such as "hydrogen" and "iridescent," shared theories and bank accounts, fended off embezzlers and industrial spies, and forged a fine "democracy of knowledge." And they had a fine time doing so, proving that scholars need not be dullards or eccentrics asocial. Uglow's spirited look at this group of remarkable "lunaticks" captures a critical, short-lived moment of early modern history. Readers who share their conviction that knowledge brings power will find this book a rewarding adventure. --Gregory McNamee

    After World War II, it reshaped the global order-whoever could master uranium could master the world. Marie Curie gave us hope that uranium would be a miracle panacea, but the Manhattan Project gave us reason to believe that civilization would end with apocalypse. Slave labor camps in Africa and Eastern Europe were built around mine shafts and America would knowingly send more than six hundred uranium miners to their graves in the name of national security. Fortunes have been made from this yellow dirt; massive energy grids have been run from it. Fear of it panicked the American people into supporting a questionable war with Iraq and its specter threatens to create another conflict in Iran. Now, some are hoping it can help avoid a global warming catastrophe. In "Uranium," Tom Zoellner takes readers around the globe in this intriguing look at the mineral that can sustain life or destroy it.

    When the first underwater “habitat” called Sealab was tested in the early 1960s, conventional dives had strict depth limits and lasted for only minutes, not the hours and even days that the visionaries behind Sealab wanted to achieve—for purposes of exploration, scientific research, and to recover submarines and aircraft that had sunk along the continental shelf. The unlikely father of Sealab, George Bond, was a colorful former country doctor who joined the Navy later in life and became obsessed with these unanswered questions: How long can a diver stay underwater? How deep can a diver go?Sealab never received the attention it deserved, yet the program inspired explorers like Jacques Cousteau, broke age-old depth barriers, and revolutionized deep-sea diving by demonstrating that living on the seabed was not science fiction. Today divers on commercial oil rigs and Navy divers engaged in classified missions rely on methods pioneered during Sealab.Sealab is a true story of heroism and discovery: men unafraid to test the limits of physical endurance to conquer a hostile undersea frontier. It is also a story of frustration and a government unwilling to take the same risks underwater that it did in space.Ben Hellwarth, a veteran journalist, interviewed many surviving participants from the three Sealab experiments and conducted extensive documentary research to write the first comprehensive account of one of the most important and least known experiments in US history.

    Written with clarity and a dazzling intellectual passion, it is both a seminal work of modern geology and a compelling precursor to Darwinism, exploring the evidence for radical changes in climate and geography across the ages and speculating on the progressive development of life. A profound influence on Darwin, Principles of Geology also captured the imagination of contemporaries such as Melville, Emerson, Tennyson and George Eliot, transforming science with its depiction of the powerful forces that shape the natural world.

    Locked within each of these extra-terrestrial objects is the 4.6-billion-year wisdom of Solar System events, and by studying them at close quarters using spacecraft we can coerce them into revealing their closely-guarded secrets. This offers us the chance to answer some fundamental questions about our planet and its inhabitants. Exploring comets and asteroids also allows us to shape the story of Earth's future, enabling us to protect our precious planet from the threat of a catastrophic impact from space, and maybe to even recover valuable raw materials from them. This cosmic bounty could be as useful in space as it is on Earth, providing the necessary fuel and supplies for humans as they voyage into deep space to explore more distant locations within the Solar System. Catching Stardust tells the story of these enigmatic celestial objects, revealing how scientists are using them to help understand a crucial time in our history – the birth of the Solar System, and everything contained within it.

    It provides scriptural solutions to life altering problems such as low self-esteem, abuse, and depression. Black Girls Don’t Cry frees us from the bondage of regrets, encourages us to drop the baggage from our past, and moves us forward towards a renewed strength in Christ.
