A cyber-enigma with an enthusiastic following, it pops up in headlines and fuels endless media debate. You can apparently use it to buy anything from coffee to cars, yet few people seem to truly understand what it is. This raises the question: Why should anyone care about bitcoin?In The Age of Cryptocurrency, Wall Street journalists Paul Vigna and Michael J. Casey deliver the definitive answer to this question. Cybermoney is poised to launch a revolution, one that could reinvent traditional financial and social structures while bringing the world's billions of "unbanked" individuals into a new global economy. Cryptocurrency holds the promise of a financial system without a middleman, one owned by the people who use it and one safeguarded from the devastation of a 2008-type crash.But bitcoin, the most famous of the cybermonies, carries a reputation for instability, wild fluctuation, and illicit business; some fear it has the power to eliminate jobs and to upend the concept of a nation state. It implies, above all, monumental and wide-reaching change-for better and for worse. But it is here to stay, and you ignore it at your peril.Vigna and Casey demystify cryptocurrency-its origins, its function, and what you need to know to navigate a cyber-economy. The digital currency world will look very different from the paper currency world; The Age of Cryptocurrency will teach you how to be ready.

    Today, twenty million people worldwide are surfing the Net. Where Wizards Stay Up Late is the exciting story of the pioneers responsible for creating the most talked about, most influential, and most far-reaching communications breakthrough since the invention of the telephone. In the 1960's, when computers where regarded as mere giant calculators, J.C.R. Licklider at MIT saw them as the ultimate communications devices. With Defense Department funds, he and a band of visionary computer whizzes began work on a nationwide, interlocking network of computers. Taking readers behind the scenes, Where Wizards Stay Up Late captures the hard work, genius, and happy accidents of their daring, stunningly successful venture.

    This increasingly ubiquitous, immensely powerful technology often leads us to assume that as the number of people online grows, it inevitably leads to a smaller, more cosmopolitan world. We’ll understand more, we think. We’ll know more. We’ll engage more and share more with people from other cultures. In reality, it is easier to ship bottles of water from Fiji to Atlanta than it is to get news from Tokyo to New York.In Rewire, media scholar and activist Ethan Zuckerman explains why the technological ability to communicate with someone does not inevitably lead to increased human connection. At the most basic level, our human tendency to “flock together” means that most of our interactions, online or off, are with a small set of people with whom we have much in common. In examining this fundamental tendency, Zuckerman draws on his own work as well as the latest research in psychology and sociology to consider technology’s role in disconnecting ourselves from the rest of the world.For those who seek a wider picture—a picture now critical for survival in an age of global economic crises and pandemics—Zuckerman highlights the challenges, and the headway already made, in truly connecting people across cultures. From voracious xenophiles eager to explore other countries to bridge figures who are able to connect one culture to another, people are at the center of his vision for a true kind of cosmopolitanism. And it is people who will shape a new approach to existing technologies, and perhaps invent some new ones, that embrace translation, cross-cultural inspiration, and the search for new, serendipitous experiences.Rich with Zuckerman’s personal experience and wisdom, Rewire offers a map of the social, technical, and policy innovations needed to more tightly connect the world.

    In the first-ever history about the organization, New York Times bestselling author Annie Jacobsen draws on inside sources, exclusive interviews, private documents, and declassified memos to paint a picture of DARPA, or "the Pentagon's brain," from its Cold War inception in 1958 to the present.This is the book on DARPA--a compelling narrative about this clandestine intersection of science and the American military and the often frightening results.

    There are updates throughout the book as well. These take into account important advances in cognitive psychology and the science of design while confirming and extending the book's basic thesis: that a physical symbol system has the necessary and sufficient means for intelligent action. The chapter "Economic Reality" has also been revised to reflect a change in emphasis in Simon's thinking about the respective roles of organizations and markets in economic systems."People sometimes ask me what they should read to find out about artificial intelligence. Herbert Simon's book The Sciences of the Artificial is always on the list I give them. Every page issues a challenge to conventional thinking, and the layman who digests it well will certainly understand what the field of artificial intelligence hopes to accomplish. I recommend it in the same spirit that I recommend Freud to people who ask about psychoanalysis, or Piaget to those who ask about child psychology: If you want to learn about a subject, start by reading its founding fathers." -- George A. Miller

    We are surprised when new competitors burst on the scene, or businesses protected by large and deep moats find their defenses easily breached, or vast new markets are conjured from nothing. Trend lines resemble saw-tooth mountain ridges.The world not only feels different. The data tell us it is different. Based on years of research by the directors of the McKinsey Global Institute, No Ordinary Disruption: The Four Forces Breaking all the Trends is a timely and important analysis of how we need to reset our intuition as a result of four forces colliding and transforming the global economy: the rise of emerging markets, the accelerating impact of technology on the natural forces of market competition, an aging world population, and accelerating flows of trade, capital and people.Our intuitions formed during a uniquely benign period for the world economy—often termed the Great Moderation. Asset prices were rising, cost of capital was falling, labour and resources were abundant, and generation after generation was growing up more prosperous than their parents.But the Great Moderation has gone. The cost of capital may rise. The price of everything from grain to steel may become more volatile. The world's labor force could shrink. Individuals, particularly those with low job skills, are at risk of growing up poorer than their parents.What sets No Ordinary Disruption apart is depth of analysis combined with lively writing informed by surprising, memorable insights that enable us to quickly grasp the disruptive forces at work. For evidence of the shift to emerging markets, consider the startling fact that, by 2025, a single regional city in China—Tianjin—will have a GDP equal to that of the Sweden, of that, in the decades ahead, half of the world's economic growth will comefrom 440 cities including Kumasi in Ghana or Santa Carina in Brazil that most executives today would be hard-pressed to locate on a map.What we are now seeing is no ordinary disruption but the new facts of business life— facts that require executives and leaders at all levels to reset their operating assumptions and management intuition.

    She very eloquently shows us why and how education needs to change...Teacher made me laugh and cry. I loved it!' - Kathy Margolis, former teacher and activist.Watching children learn is a beautiful and extraordinary experience. Their bodies transform, reflecting inner changes. Teeth fall out. Knees scab. Freckles multiply. Throughout the year they grow in endless ways and I can almost see their self-esteem rising, their confidence soaring, their small bodies now empowered. Given wings.They fall in love with learning.It is a kind of magic, a kind of loving, a kind of art.It is teaching.Just teaching.Just what I do.What I did.Past tense.In 2014, Gabrielle Stroud was a very dedicated teacher with over a decade of experience. Months later, she resigned in frustration and despair when she realised that the Naplan-test education model was stopping her from doing the very thing she was best at: teaching individual children according to their needs and talents. Her ground-breaking essay 'Teaching Australia' in the Feb 2016 Griffith Review outlined her experiences and provoked a huge response from former and current teachers around the world. That essay lifted the lid on a scandal that is yet to properly break - that our education system is unfair to our children and destroying their teachers. In a powerful memoir inspired by her original essay, Gabrielle tells the full story: how she came to teaching, what makes a great teacher, what our kids need from their teachers, and what it was that finally broke her. A brilliant and heart-breaking memoir that cuts to the heart of a vital matter of national importance.

    Scientists have made progress: computers can now beat chess grandmasters and help prevent terrorist attacks. Yet we still await a machine that exhibits the rich complexity of human thought — one that doesn’t just crunch numbers, or take us to a relevant Web page, but understands us and gives us what we need.That vision has driven a team of engineers at IBM. Over three years, they created “Watson” and prepared it for a showdown on Jeopardy!, where it would take on two of the game’s all-time champions, Ken Jennings and Brad Rutter, in a nationally televised event. Final Jeopardy is the entertaining, illuminating story of that computer and that epic match.It’s a classic tale of Man vs. Machine. Like its human competitors, Watson has to understand language, including puns and irony, and master everything from history, literature, and science to arts, entertainment, and game strategy. After years of training, Watson can find the scrambled state capital in “Hair Gel” (“What is Raleigh?”) and even come up with the facial accessory that made Moshe Dayan recognizable worldwide (“What is an eye patch?”). Watson may just be the smartest machine on earth.Final Jeopardy traces the arc of Watson’s “life,” from its birth in the IBM labs to its big night on the podium. We meet Hollywood moguls and Jeopardy! masters, genius computer programmers and ambitious scientists, including Watson’s eccentric creator, David Ferrucci. We gain access to Ferrucci’s War Room, where the IBM team works tirelessly to boost Watson’s speed to the buzzer, improve its performance in “train wreck” categories (such as “Books in Español”), and fix glitches like the speech defect Watson developed during its testing phase, when it started adding a d to words ending in n (“What is Pakistand?”).Much is at stake, especially for IBM. A new generation of Watsons could transform medicine, the law, marketing, even science itself, as machines process huge amounts of data at lightning speed, answer our questions, and possibly come up with new hypotheses.Showdown aside, it’s clear that the future has arrived. But with it come questions: Where does it leave humans? What will Watson’s heirs be capable of in ten or twenty years? Is it time to declare defeat in the realm of facts? What should we teach our children? And what should we carry around in our own heads?Final Jeopardy takes on these questions and more in a narrative that’s as fast and fun as the game itself. Baker shows us how smart machines will fit into our world — and how they’ll disrupt it. www.finaljeopardy.net

    It means more than the arrival of trendy shops, much-maligned hipsters, and expensive lattes. The very future of American cities as vibrant, equitable spaces hangs in the balance.Peter Moskowitz's How to Kill a City takes readers from the kitchen tables of hurting families who can no longer afford their homes to the corporate boardrooms and political backrooms where destructive housing policies are devised. Along the way, Moskowitz uncovers the massive, systemic forces behind gentrification in New Orleans, Detroit, San Francisco, and New York. The deceptively simple question of who can and cannot afford to pay the rent goes to the heart of America's crises of race and inequality. In the fight for economic opportunity and racial justice, nothing could be more important than housing.A vigorous, hard-hitting expose, How to Kill a City reveals who holds power in our cities-and how we can get it back

    By spinning 28 mathematical tales, Orlin shows us that calculus is simply another language to express the very things we humans grapple with every day -- love, risk, time, and most importantly, change. Divided into two parts, "Moments" and "Eternities," and drawing on everyone from Sherlock Holmes to Mark Twain to David Foster Wallace, Change is the Only Constant unearths connections between calculus, art, literature, and a beloved dog named Elvis. This is not just math for math's sake; it's math for the sake of becoming a wiser and more thoughtful human.

    The Perfect Weapon is the riveting story of how, in less than a decade, cyberwarfare displaced terrorism and nuclear attacks as the greatest threat to American national security. Cheap to acquire, difficult to defend against, and designed to shield their user's identities so as to complicate retaliation, these weapons are capable of an unprecedented range of offensive tactics; they can take us just short of war, allowing for everything from disruption to theft to the cause of widespread damage of essential infrastructure systems. And the vulnerability of those systems has created a related but equally urgent conflict: American companies like Apple and Cisco must claim allegiance to no government in the name of selling secure products around the globe yet the US intelligence agencies want the help of such companies in defending against future cyberattacks. Reported and written with unprecedented access by New York Times chief Washington correspondent and bestselling author David Sanger, The Perfect Weapon takes readers inside war rooms and boardrooms, into the secret cyberdens of American and Chinese military, to give the deep-background story of the increasingly pitched battle between nations, their governments, their cyberwarriors, and their corporations.

    Language is humanity's most spectacular open-source project, and the internet is making our language change faster and in more interesting ways than ever before. Internet conversations are structured by the shape of our apps and platforms, from the grammar of status updates to the protocols of comments and @replies. Linguistically inventive online communities spread new slang and jargon with dizzying speed. What's more, social media is a vast laboratory of unedited, unfiltered words where we can watch language evolve in real time.Even the most absurd-looking slang has genuine patterns behind it. Internet linguist Gretchen McCulloch explores the deep forces that shape human language and influence the way we communicate with one another. She explains how your first social internet experience influences whether you prefer "LOL" or "lol," why ~sparkly tildes~ succeeded where centuries of proposals for irony punctuation had failed, what emoji have in common with physical gestures, and how the artfully disarrayed language of animal memes like lolcats and doggo made them more likely to spread.Because Internet is essential reading for anyone who's ever puzzled over how to punctuate a text message or wondered where memes come from. It's the perfect book for understanding how the internet is changing the English language, why that's a good thing, and what our online interactions reveal about who we are.
