It has built on itself for centuries, becoming vast and increasingly specialized. Most of us are ignorant about the fundamental principles of the civilization that supports us, happily utilizing the latest—or even the most basic—technology without having the slightest idea of why it works or how it came to be. If you had to go back to absolute basics, like some sort of postcataclysmic Robinson Crusoe, would you know how to re-create an internal combustion engine, put together a microscope, get metals out of rock, accurately tell time, weave fibers into clothing, or even how to produce food for yourself? Regarded as one of the brightest young scientists of his generation, Lewis Dartnell proposes that the key to preserving civilization in an apocalyptic scenario is to provide a quickstart guide, adapted to cataclysmic circumstances. The Knowledge describes many of the modern technologies we employ, but first it explains the fundamentals upon which they are built. Every piece of technology rests on an enormous support network of other technologies, all interlinked and mutually dependent. You can’t hope to build a radio, for example, without understanding how to acquire the raw materials it requires, as well as generate the electricity needed to run it. But Dartnell doesn’t just provide specific information for starting over; he also reveals the greatest invention of them all—the phenomenal knowledge-generating machine that is the scientific method itself. This would allow survivors to learn technological advances not explicitly explored in The Knowledge as well as things we have yet to discover. The Knowledge is a brilliantly original guide to the fundamentals of science and how it built our modern world as well as a thought experiment about the very idea of scientific knowledge itself.

    Confusing messages from health authorities and ineffective treatments have left many people desperate for reliable solutions. An enormous alternative industry is filling the void, selling products that are often of questionable safety and totally unknown effectiveness.In Clean, doctor and journalist James Hamblin explores how we got here, examining the science and culture of how we care for our skin today. He talks to dermatologists, microbiologists, allergists, immunologists, aestheticians, bar-soap enthusiasts, venture capitalists, Amish people, theologians, and straight-up scam artists, trying to figure out what it really means to be clean. He even experiments with giving up showers entirely, and discovers that he is not alone.Along the way he realizes that most of our standards of cleanliness are less related to health than most people think. A major part of the picture has been missing: a little-known ecosystem known as the skin microbiome--the trillions of microbes that live on our skin and in our pores. These microbes are not dangerous; they're more like an outer layer of skin that no one knew we had, and they influence everything from acne, eczema, and dry skin to how we smell. The new goal of skin care will be to cultivate a healthy biome--and to embrace the meaning of "clean" in the natural sense. This can mean doing much less, saving time, money, energy, water, and plastic bottles in the process.Lucid, accessible, and deeply researched, Clean explores the ongoing, radical change in the way we think about our skin, introducing readers to the emerging science that will be at the forefront of health and wellness conversations in coming years.

    This staggering amount of information—unprecedented in history—can tell us a great deal about who we are—the fears, desires, and behaviors that drive us, and the conscious and unconscious decisions we make. From the profound to the mundane, we can gain astonishing knowledge about the human psyche that less than twenty years ago, seemed unfathomable.Everybody Lies offers fascinating, surprising, and sometimes laugh-out-loud insights into everything from economics to ethics to sports to race to sex, gender and more, all drawn from the world of big data. What percentage of white voters didn’t vote for Barack Obama because he’s black? Does where you go to school effect how successful you are in life? Do parents secretly favor boy children over girls? Do violent films affect the crime rate? Can you beat the stock market? How regularly do we lie about our sex lives and who’s more self-conscious about sex, men or women?Investigating these questions and a host of others, Seth Stephens-Davidowitz offers revelations that can help us understand ourselves and our lives better. Drawing on studies and experiments on how we really live and think, he demonstrates in fascinating and often funny ways the extent to which all the world is indeed a lab. With conclusions ranging from strange-but-true to thought-provoking to disturbing, he explores the power of this digital truth serum and its deeper potential—revealing biases deeply embedded within us, information we can use to change our culture, and the questions we’re afraid to ask that might be essential to our health—both emotional and physical. All of us are touched by big data everyday, and its influence is multiplying. Everybody Lies challenges us to think differently about how we see it and the world.

    A desperate search for reunion with dead loved ones precipitated a tidal wave of self-proclaimed psychics—and, as reputable media sought stories on occult phenomena, mediums became celebrities. Against this backdrop, in 1924, the pretty wife of a distinguished Boston surgeon came to embody the raging national debate over Spiritualism, a movement devoted to communication with the dead. Reporters dubbed her the blonde Witch of Lime Street, but she was known to her followers simply as Margery. Her most vocal advocate was none other than Sherlock Holmes' creator Sir Arthur Conan Doyle, who believed so thoroughly in Margery's powers that he urged her to enter a controversial contest, sponsored by Scientific American and offering a large cash prize to the first medium declared authentic by its impressive five-man investigative committee.  Admired for both her exceptional charm and her dazzling effects, Margery was the best hope for the psychic practice to be empirically verified.  Her supernatural gifts beguiled four of the judges. There was only one left to convince...the acclaimed escape artist, Harry Houdini.David Jaher's extraordinary debut culminates in the showdown between Houdini, a relentless unmasker of charlatans, and Margery, the nation's most credible spirit medium. The Witch of Lime Street, the first book to capture their electric public rivalry and the competition that brought them into each other’s orbit, returns us to an oft-mythologized era to deepen our understanding of its history, all while igniting our imagination and engaging with the timeless question: Is there life after death?

    In the last fifty years, we've zoomed through radically different forms of communication, from typewriters to tablet computers, text messages to tweets. We generate more and more words with each passing day. Hiding in that deluge of language are amazing insights into who we are, how we think, and what we feel.In The Secret Life of Pronouns, social psychologist and language expert James W. Pennebaker uses his groundbreaking research in computational linguistics-in essence, counting the frequency of words we use-to show that our language carries secrets about our feelings, our self-concept, and our social intelligence. Our most forgettable words, such as pronouns and prepositions, can be the most revealing: their patterns are as distinctive as fingerprints.Using innovative analytic techniques, Pennebaker X-rays everything from Craigslist advertisements to the Federalist Papers-or your own writing, in quizzes you can take yourself-to yield unexpected insights. Who would have predicted that the high school student who uses too many verbs in her college admissions essay is likely to make lower grades in college? Or that a world leader's use of pronouns could reliably presage whether he led his country into war? You'll learn why it's bad when politicians use "we" instead of "I," what Lady Gaga and William Butler Yeats have in common, and how Ebenezer Scrooge's syntax hints at his self-deception and repressed emotion. Barack Obama, Sylvia Plath, and King Lear are among the figures who make cameo appearances in this sprightly, surprising tour of what our words are saying-whether we mean them to or not.

    English is a glorious mess of a language, cobbled together from a wide variety of sources and syntaxes, and changing over time with popular usage. Many of the words and usages we embrace as standard and correct today were at first considered slang, impolite, or just plain wrong. Filled with historic and contemporary examples, the book chronicles the long and entertaining history of language mistakes, and features some of our most common words and phrases. This is a book that will settle arguments among word lovers—and it’s sure to start a few, too.
