A simple web search picks out a handful of relevant needles from the world's biggest haystack: the billions of pages on the World Wide Web. Uploading a photo to Facebook transmits millions of pieces of information over numerous error-prone network links, yet somehow a perfect copy of the photo arrives intact. Without even knowing it, we use public-key cryptography to transmit secret information like credit card numbers; and we use digital signatures to verify the identity of the websites we visit. How do our computers perform these tasks with such ease? This is the first book to answer that question in language anyone can understand, revealing the extraordinary ideas that power our PCs, laptops, and smartphones. Using vivid examples, John MacCormick explains the fundamental "tricks" behind nine types of computer algorithms, including artificial intelligence (where we learn about the "nearest neighbor trick" and "twenty questions trick"), Google's famous PageRank algorithm (which uses the "random surfer trick"), data compression, error correction, and much more. These revolutionary algorithms have changed our world: this book unlocks their secrets, and lays bare the incredible ideas that our computers use every day.

    Levitt, co-author of Freakonomics - One of the best books of the year--NatureMary Aiken, the world's leading expert in forensic cyberpsychology, offers a starting point for all future conversations about how the Internet is shaping development and behavior, societal norms and values, children, safety, privacy, and our perception of the world.

    Every year the Intel International Science & Engineering Fair brings together 1,500 high schoolers from more than 50 countries to compete for over $4 million dollars in prizes and scholarships. These amazing kids are doing everything from creating bionic prosthetics to conducting groundbreaking stem cell research, from training drug-sniffing cockroaches to building a nuclear reactor. In Science Fair Season, Judy Dutton follows twelve teens looking for science fair greatness and tells the gripping stories of their road to the big competition. Some will win, some will lose, but all of their lives are changed forever. The Intel International Science & Engineering Fair is the most prominent science fair in the country, and it takes a special blend of drive, heart, and smarts to win there. Dutton goes inside the inner sanctum of science fair competitions and reveals the awe-inspiring projects and the competitors there. Each of the kids ranging from a young Erin Brokovich who made the FBI watch list for taking on a big corporation, to a quietly driven boy who lives in a run-down trailer on a Navajo reservation, to a wealthy Connecticut girl who dreams of being an actress and finds her calling studying bees, to a troubled teenager in a juvenile detention facility, to the next Bill Gates take readers on an unforgettable journey.Along the way, Science Fair Season gives readers a glimpse of the future bright minds of America and shows how our country is still a place for inventors and dreamers, and that the "geeks" will truly inherit the earth.

    The Structure of Scientific Revolutions is that kind of book. When it was first published in 1962, it was a landmark event in the history and philosophy of science. Fifty years later, it still has many lessons to teach. With The Structure of Scientific Revolutions, Kuhn challenged long-standing linear notions of scientific progress, arguing that transformative ideas don’t arise from the day-to-day, gradual process of experimentation and data accumulation but that the revolutions in science, those breakthrough moments that disrupt accepted thinking and offer unanticipated ideas, occur outside of “normal science,” as he called it. Though Kuhn was writing when physics ruled the sciences, his ideas on how scientific revolutions bring order to the anomalies that amass over time in research experiments are still instructive in our biotech age. This new edition of Kuhn’s essential work in the history of science includes an insightful introduction by Ian Hacking, which clarifies terms popularized by Kuhn, including paradigm and incommensurability, and applies Kuhn’s ideas to the science of today. Usefully keyed to the separate sections of the book, Hacking’s introduction provides important background information as well as a contemporary context.  Newly designed, with an expanded index, this edition will be eagerly welcomed by the next generation of readers seeking to understand the history of our perspectives on science.

    Much-publicized experiments, often underwritten by Silicon Valley entrepreneurs, have been launched at elite universities and in elementary schools in the poorest neighborhoods. Such was the excitement that, in 2012, the New York Times declared the "year of the MOOC." Less than a decade later, that pronouncement seems premature.In Failure to Disrupt: Why Technology Alone Can't Transform Education, Justin Reich delivers a sobering report card on the latest supposedly transformative educational technologies. Reich takes readers on a tour of MOOCs, autograders, computerized "intelligent tutors," and other educational technologies whose problems and paradoxes have bedeviled educators. Learning technologies--even those that are free to access--often provide the greatest benefit to affluent students and do little to combat growing inequality in education. And institutions and investors often favor programs that scale up quickly, but at the expense of true innovation. It turns out that technology cannot by itself disrupt education or provide shortcuts past the hard road of institutional change.Technology does have a crucial role to play in the future of education, Reich concludes. We still need new teaching tools, and classroom experimentation should be encouraged. But successful reform efforts will focus on incremental improvements, not the next killer app.

    But how do we know what today's learners will really need to know in the future? Future Wise: Educating Our Children for a Changing World is a toolkit for approaching that question with new insight. There is no one answer to the question of what's worth teaching, but with the tools in this book, you'll be one step closer to constructing a curriculum that prepares students for whatever situations they might face in the future.K-12 teachers and administrators play a crucial role in building a thriving society. David Perkins, founding member and co-director of Project Zero at Harvard's Graduate School of Education, argues that curriculum is one of the most important elements of making students ready for the world of tomorrow. In Future Wise, you'll learn concepts, curriculum criteria, and techniques for prioritizing content so you can guide students toward the big understandings that matter.Understand how learners use knowledge in life after graduation Learn strategies for teaching critical thinking and addressing big questions Identify top priorities when it comes to disciplines and content areas Gain curriculum design skills that make the most of learning across the years of education Future Wise presents a brand new framework for thinking about education. Curriculum can be one of the hardest things for teachers and administrators to change, but David Perkins shows that only by reimagining what we teach can we lead students down the road to functional knowledge. Future Wise is the practical guidebook you need to embark on this important quest.

    But with the unexpected death of her husband, her life became an empty, lightless space. Suddenly she was the single mother of two young boys, a widow at forty, clinging to three crumpled pages of instructions her husband had written for things like grocery shopping--things he had done while she did pioneering work as a planetary scientist at MIT. She became painfully conscious of her Asperger's, which before losing her husband had felt more like background noise. She felt, for the first time, alone in the universe.In this probing, invigoratingly honest memoir, Seager tells the story of how, as she stumblingly navigated the world of grief, she also kept looking for other worlds. She continues to develop groundbreaking projects, such as the Starshade, a sunflower-shaped instrument that, when launched into space, unfurls itself so as to block planet-obscuring starlight, and she takes solace in the alien beauty of exoplanets. At the same time, she discovers what feels every bit as wondrous: other people, reaching out across the space of her grief. Among them are the Widows of Concord, a group of women offering consolation and advice; and her beloved sons, Max and Alex. Most unexpected of all, there is another kind of one-in-a-billion match with an amateur astronomer.Equally attuned to the wonders of deep space and human connection, The Smallest Lights in the Universe is its own light in the dark.

    His goal: to learn how such an overhyped industry could possibly sustain itself as long as it has. Determined to cut through the clichés of big tech—the relentless optimism, the incessant repetition of vacuous buzzwords—Pein decided that he would need to take an approach as unorthodox as the companies he would soon be covering. To truly understand the delirious reality of a Silicon Valley entrepreneur, he knew, he would have to inhabit that perspective—he would have to become an entrepreneur. Thus he begins his journey—skulking through gimmicky tech conferences, pitching his over-the-top business ideas to investors, and interviewing a cast of outrageous characters: cyborgs and con artists, Teamsters and transhumanists, jittery hackers and naive upstart programmers whose entire lives are managed by their employers—who work endlessly and obediently, never thinking to question their place in the system.In showing us this frantic world, Pein challenges the positive self-image that the tech tycoons have crafted—as benevolent creators of wealth and opportunity—to reveal their self-justifying views and their insidious visions for the future. Vivid and incisive, Live Work Work Work Die is a troubling portrait of a self-obsessed industry bent on imposing its disturbing visions on the rest of us.

    We obsess over our emails, Instagram likes, and Facebook feeds; we binge on TV episodes and YouTube videos; we work longer hours each year; and we spend an average of three hours each day using our smartphones. Half of us would rather suffer a broken bone than a broken phone, and Millennial kids spend so much time in front of screens that they struggle to interact with real, live humans. In this revolutionary book, Adam Alter, a professor of psychology and marketing at NYU, tracks the rise of behavioral addiction, and explains why so many of today's products are irresistible. Though these miraculous products melt the miles that separate people across the globe, their extraordinary and sometimes damaging magnetism is no accident. The companies that design these products tweak them over time until they become almost impossible to resist. By reverse engineering behavioral addiction, Alter explains how we can harness addictive products for the good—to improve how we communicate with each other, spend and save our money, and set boundaries between work and play—and how we can mitigate their most damaging effects on our well-being, and the health and happiness of our children.

    Now, two science professors give us the tools to dismantle misinformation and think clearly in a world of fake news and bad data.It's increasingly difficult to know what's true. Misinformation, disinformation, and fake news abound. Our media environment has become hyperpartisan. Science is conducted by press release. Startup culture elevates bullshit to high art. We are fairly well equipped to spot the sort of old-school bullshit that is based in fancy rhetoric and weasel words, but most of us don't feel qualified to challenge the avalanche of new-school bullshit presented in the language of math, science, or statistics. In Calling Bullshit, Professors Carl Bergstrom and Jevin West give us a set of powerful tools to cut through the most intimidating data.You don't need a lot of technical expertise to call out problems with data. Are the numbers or results too good or too dramatic to be true? Is the claim comparing like with like? Is it confirming your personal bias? Drawing on a deep well of expertise in statistics and computational biology, Bergstrom and West exuberantly unpack examples of selection bias and muddled data visualization, distinguish between correlation and causation, and examine the susceptibility of science to modern bullshit.We have always needed people who call bullshit when necessary, whether within a circle of friends, a community of scholars, or the citizenry of a nation. Now that bullshit has evolved, we need to relearn the art of skepticism.

    His invention of the first practical incandescent lamp 140 years ago so dazzled the world--already reeling from his invention of the phonograph and dozens of other revolutionary devices--that it cast a shadow over his later achievements. In all, this near-deaf genius ("I haven't heard a bird sing since I was twelve years old") patented 1,093 inventions, not including others, such as the X-ray fluoroscope, that he left unlicensed for the benefit of medicine.One of the achievements of this staggering new biography, the first major life of Edison in more than twenty years, is that it portrays the unknown Edison--the philosopher, the futurist, the chemist, the botanist, the wartime defense adviser, the founder of nearly 250 companies--as fully as it deconstructs the Edison of mythological memory. Edmund Morris, winner of the Pulitzer Prize and the National Book Award, brings to the task all the interpretive acuity and literary elegance that distinguished his previous biographies of Theodore Roosevelt, Ronald Reagan, and Ludwig van Beethoven. A trained musician, Morris is especially well equipped to recount Edison's fifty-year obsession with recording technology and his pioneering advances in the synchronization of movies and sound. Morris sweeps aside conspiratorial theories positing an enmity between Edison and Nikola Tesla and presents proof of their mutually admiring, if wary, relationship.Enlightened by seven years of research among the five million pages of original documents preserved in Edison's huge laboratory at West Orange, New Jersey, and privileged access to family papers still held in trust, Morris is also able to bring his subject to life on the page--the adored yet autocratic and often neglectful husband of two wives and father of six children. If the great man who emerges from it is less a sentimental hero than an overwhelming force of nature, driven onward by compulsive creativity, then Edison is at last getting his biographical due.

    He explores what parents, teachers, and employers must do to develop the capacities of young people to become innovators. In profiling compelling young American innovators such as Kirk Phelps, product manager for Apple’s first iPhone, and Jodie Wu, who founded a company that builds bicycle-powered maize shellers in Tanzania, Wagner reveals how the adults in their lives nurtured their creativity and sparked their imaginations, while teaching them to learn from failures and persevere. Wagner identifies a pattern—a childhood of creative play leads to deep-seated interests, which in adolescence and adulthood blossom into a deeper purpose for career and life goals. Play, passion, and purpose: These are the forces that drive young innovators. Wagner shows how we can apply this knowledge as educators and what parents can do to compensate for poor schooling. He takes readers into the most forward-thinking schools, colleges, and workplaces in the country, where teachers and employers are developing cultures of innovation based on collaboration, interdisciplinary problem-solving, and intrinsic motivation. The result is a timely, provocative, and inspiring manifesto that will change how we look at our schools and workplaces, and provide us with a road map for creating the change makers of tomorrow. Creating Innovators will feature its own innovative elements: more than sixty original videos that expand on key ideas in the book through interviews with young innovators, teachers, writers, CEOs, and entrepreneurs, including Thomas Friedman, Dean Kamen, and Annmarie Neal. Produced by filmmaker Robert A. Compton, the videos are embedded into the ebook edition in video-enabled eReaders and accessible in this print edition via QR codes placed throughout the chapters or via www.creatinginnovators.com.

    It is the powerful story of four African-American female mathematicians at NASA who helped achieve some of the greatest moments in our space program. Now a major motion picture starring Taraji P. Henson, Octavia Spencer, Janelle Monae, Kirsten Dunst, and Kevin Costner.Before John Glenn orbited the earth, or Neil Armstrong walked on the moon, a group of dedicated female mathematicians known as “human computers” used pencils, slide rules, and adding machines to calculate the numbers that would launch rockets, and astronauts, into space.This book brings to life the stories of Dorothy Vaughan, Mary Jackson, Katherine Johnson, and Christine Darden, who lived through the Civil Rights era, the Space Race, the Cold War, and the movement for gender equality, and whose work forever changed the face of NASA and the country.

    Diligently treating the drug addicts of Vancouver's notorious Downtown Eastside with sympathy in his heart and legislative reform in mind can't be easy. But Maté never judges. His book is a powerful call-to-arms, both for the decriminalization of drugs and for a more sympathetic and informed view of addiction. As Maté observes, "Those whom we dismiss as 'junkies' are not creatures from a different world, only men and women mired at the extreme end of a continuum on which, here or there, all of us might well locate ourselves." In the Realm of Hungry Ghosts begins by introducing us to many of Dr. Maté's most dire patients who steal, cheat, sell sex, and otherwise harm themselves for their next hit. Maté looks to the root causes of addiction, applying a clinical and psychological view to the physical manifestation and offering some enlightening answers for why people inflict such catastrophe on themselves.Finally, he takes aim at the hugely ineffectual, largely U.S.-led War on Drugs (and its worldwide followers), challenging the wisdom of fighting drugs instead of aiding the addicts, and showing how controversial measures such as safe injection sites are measurably more successful at reducing drug-related crime and the spread of disease than anything most major governments have going. It's not easy reading, but we ignore his arguments at our peril. When it comes to combating the drug trade and the ravages of addiction, society can use all the help it can get. --Kim Hughes
