But what if everything we’ve been taught to believe about aging is wrong? What if we could choose our lifespan? In this groundbreaking book, Dr. David Sinclair, leading world authority on genetics and longevity, reveals a bold new theory for why we age. As he writes: “Aging is a disease, and that disease is treatable.” This book takes us to the frontlines of research many from Dr. David Sinclair’s own lab at Harvard—that demonstrate how we can slow down, or even reverse, aging. The key is activating newly discovered vitality genes, the descendants of an ancient genetic survival circuit that is both the cause of aging and the key to reversing it.

    We are increasingly coaxed from the third-dimensional containment of our pre-digital selves into a wonderful and eerie fourth dimension, a world of ceaseless communication, instant information and global connection.Our portals to this new world have been wedged open, and the silhouette of a figure is slowly taking shape. But what does it feel like to be four-dimensional? How do digital technologies influence the rhythms of our thoughts, the style and tilt of our consciousness? What new sensitivities and sensibilities are emerging with our exposure to the delights, sorrows and anxieties of a networked world? And how do we live in public, with these recoded private lives?Tackling ideas of time, space, isolation, silence and threat – how our modern-day anxieties manifest online – and moving from Hamlet to the ghosts of social media, from Seinfeld to the fall of Gaddafi, from Twitter art to Oedipus, The Four-Dimensional Human is a highly original and pioneering portrait of life in a digital landscape.

    The algorithms you'll use most often as a programmer have already been discovered, tested, and proven. If you want to take a hard pass on Knuth's brilliant but impenetrable theories and the dense multi-page proofs you'll find in most textbooks, this is the book for you. This fully-illustrated and engaging guide makes it easy for you to learn how to use algorithms effectively in your own programs.Grokking Algorithms is a disarming take on a core computer science topic. In it, you'll learn how to apply common algorithms to the practical problems you face in day-to-day life as a programmer. You'll start with problems like sorting and searching. As you build up your skills in thinking algorithmically, you'll tackle more complex concerns such as data compression or artificial intelligence. Whether you're writing business software, video games, mobile apps, or system utilities, you'll learn algorithmic techniques for solving problems that you thought were out of your grasp. For example, you'll be able to:Write a spell checker using graph algorithmsUnderstand how data compression works using Huffman codingIdentify problems that take too long to solve with naive algorithms, and attack them with algorithms that give you an approximate answer insteadEach carefully-presented example includes helpful diagrams and fully-annotated code samples in Python. By the end of this book, you will know some of the most widely applicable algorithms as well as how and when to use them.

    Edited by the Sustainability Institute’s Diana Wright, this essential primer brings systems thinking out of the realm of computers and equations and into the tangible world, showing readers how to develop the systems-thinking skills that thought leaders across the globe consider critical for 21st-century life.Some of the biggest problems facing the world—war, hunger, poverty, and environmental degradation—are essentially system failures. They cannot be solved by fixing one piece in isolation from the others, because even seemingly minor details have enormous power to undermine the best efforts of too-narrow thinking.While readers will learn the conceptual tools and methods of systems thinking, the heart of the book is grander than methodology. Donella Meadows was known as much for nurturing positive outcomes as she was for delving into the science behind global dilemmas. She reminds readers to pay attention to what is important, not just what is quantifiable, to stay humble, and to stay a learner.In a world growing ever more complicated, crowded, and interdependent, Thinking in Systems helps readers avoid confusion and helplessness, the first step toward finding proactive and effective solutions.

    Instead of giving you the most broadly popular result, Google now tries to predict what you are most likely to click on. According to MoveOn.org board president Eli Pariser, Google's change in policy is symptomatic of the most significant shift to take place on the Web in recent years - the rise of personalization. In this groundbreaking investigation of the new hidden Web, Pariser uncovers how this growing trend threatens to control how we consume and share information as a society-and reveals what we can do about it.Though the phenomenon has gone largely undetected until now, personalized filters are sweeping the Web, creating individual universes of information for each of us. Facebook - the primary news source for an increasing number of Americans - prioritizes the links it believes will appeal to you so that if you are a liberal, you can expect to see only progressive links. Even an old-media bastion like "The Washington Post" devotes the top of its home page to a news feed with the links your Facebook friends are sharing. Behind the scenes a burgeoning industry of data companies is tracking your personal information to sell to advertisers, from your political leanings to the color you painted your living room to the hiking boots you just browsed on Zappos.In a personalized world, we will increasingly be typed and fed only news that is pleasant, familiar, and confirms our beliefs - and because these filters are invisible, we won't know what is being hidden from us. Our past interests will determine what we are exposed to in the future, leaving less room for the unexpected encounters that spark creativity, innovation, and the democratic exchange of ideas.While we all worry that the Internet is eroding privacy or shrinking our attention spans, Pariser uncovers a more pernicious and far-reaching trend on the Internet and shows how we can - and must - change course. With vivid detail and remarkable scope, The Filter Bubble reveals how personalization undermines the Internet's original purpose as an open platform for the spread of ideas and could leave us all in an isolated, echoing world.

    How does Jane Goodall’s relationship with her dog Rusty inform her thinking about our relationship to other species? Which time and place would Jared Diamond most prefer to live in, in light of his work on the role of chance in history?

    So Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in tasty chapters consumable anytime and anywhere in your busy day.

    In the words of economist and scholar Arnold Kling, Martin Gurri saw it coming.Technology has categorically reversed the information balance of power between the public and the elites who manage the great hierarchical institutions of the industrial age government, political parties, the media.The Revolt of the Public tells the story of how insurgencies, enabled by digital devices and a vast information sphere, have mobilized millions of ordinary people around the world.Originally published in 2014, this updated edition of The Revolt of the Public includes an extensive analysis of Donald Trump's improbable rise to the presidency and the electoral triumphs of Brexit and concludes with a speculative look forward, pondering whether the current elite class can bring about a reformation of the democratic process and whether new organizing principles, adapted to a digital world, can arise out of the present political turbulence.

    And considering that the "one man" is Neal Stephenson, "the hacker Hemingway" (Newsweek) -- acclaimed novelist, pragmatist, seer, nerd-friendly philosopher, and nationally bestselling author of groundbreaking literary works (Snow Crash, Cryptonomicon, etc., etc.) -- the word is well worth hearing. Mostly well-reasoned examination and partial rant, Stephenson's In the Beginning... was the Command Line is a thoughtful, irreverent, hilarious treatise on the cyber-culture past and present; on operating system tyrannies and downloaded popular revolutions; on the Internet, Disney World, Big Bangs, not to mention the meaning of life itself.

    Thiel's sexuality had been known to close friends and family, but he didn't consider himself a public figure, and believed the information was private. This post would be the casus belli for a meticulously plotted conspiracy that would end nearly a decade later with a $140 million dollar judgment against Gawker, its bankruptcy and with Nick Denton, Gawker's CEO and founder, out of a job. Only later would the world learn that Gawker's demise was not incidental--it had been masterminded by Thiel.For years, Thiel had searched endlessly for a solution to what he'd come to call the "Gawker Problem." When an unmarked envelope delivered an illegally recorded sex tape of Hogan with his best friend's wife, Gawker had seen the chance for millions of pageviews and to say the things that others were afraid to say. Thiel saw their publication of the tape as the opportunity he was looking for. He would come to pit Hogan against Gawker in a multi-year proxy war through the Florida legal system, while Gawker remained confidently convinced they would prevail as they had over so many other lawsuit--until it was too late. The verdict would stun the world and so would Peter's ultimate unmasking as the man who had set it all in motion. Why had he done this? How had no one discovered it? What would this mean--for the First Amendment? For privacy? For culture?In Holiday's masterful telling of this nearly unbelievable conspiracy, informed by interviews with all the key players, this case transcends the narrative of how one billionaire took down a media empire or the current state of the free press. It's a study in power, strategy, and one of the most wildly ambitious--and successful--secret plots in recent memory.Some will cheer Gawker's destruction and others will lament it, but after reading these pages--and seeing the access the author was given--no one will deny that there is something ruthless and brilliant about Peter Thiel's shocking attempt to shake up the world.

    In this lively book of essays, Stephen Wolfram takes the reader along on some of his most surprising and engaging intellectual adventures in science, technology, artificial intelligence and language design.

    The data compiled and portraits created are incredibly detailed, to the point of being invasive. But who connects the dots about what firms are doing with this information? The Black Box Society argues that we all need to be able to do so--and to set limits on how big data affects our lives.Hidden algorithms can make (or ruin) reputations, decide the destiny of entrepreneurs, or even devastate an entire economy. Shrouded in secrecy and complexity, decisions at major Silicon Valley and Wall Street firms were long assumed to be neutral and technical. But leaks, whistleblowers, and legal disputes have shed new light on automated judgment. Self-serving and reckless behavior is surprisingly common, and easy to hide in code protected by legal and real secrecy. Even after billions of dollars of fines have been levied, underfunded regulators may have only scratched the surface of this troubling behavior.Frank Pasquale exposes how powerful interests abuse secrecy for profit and explains ways to rein them in. Demanding transparency is only the first step. An intelligible society would assure that key decisions of its most important firms are fair, nondiscriminatory, and open to criticism. Silicon Valley and Wall Street need to accept as much accountability as they impose on others.

    He is also an obsessive gamer who has spent untold hours in front of his various video game consoles, playing titles such as Far Cry 2, Left 4 Dead, BioShock, and Oblivion for, literally, days. If you are reading this flap copy, the same thing can probably be said of you, or of someone you know. Until recently, Bissell was somewhat reluctant to admit to his passion for games. In this, he is not alone. Millions of adults spend hours every week playing video games, and the industry itself now reliably outearns Hollywood. But the wider culture seems to regard video games as, at best, well designed if mindless entertainment. Extra Lives is an impassioned defense of this assailed and misunderstood art form. Bissell argues that we are in a golden age of gaming—but he also believes games could be even better. He offers a fascinating and often hilarious critique of the ways video games dazzle and, just as often, frustrate. Along the way, we get firsthand portraits of some of the best minds (Jonathan Blow, Clint Hocking, Cliff Bleszinski, Peter Molyneux) at work in video game design today, as well as a shattering and deeply moving final chapter that describes, in searing detail, Bissell’s descent into the world of Grand Theft Auto IV, a game whose themes mirror his own increasingly self-destructive compulsions. Blending memoir, criticism, and first-rate reportage, Extra Lives is like no other book on the subject ever published. Whether you love video games, loathe video games, or are merely curious about why they are becoming the dominant popular art form of our time, Extra Lives is required reading.

    Some businesses--like home exercise company Peloton, video conference software maker Zoom, and Amazon--woke up to find themselves crushed under an avalanche of consumer demand. Others--like the restaurant, travel, hospitality, and live entertainment industries--scrambled to escape obliteration.But as Scott Galloway argues, the pandemic has not been a change agent so much as an accelerant of trends already well underway. In Post Corona, he outlines the contours of the crisis and the opportunities that lie ahead. Some businesses, like the powerful tech monopolies, will thrive as a result of the disruption. Other industries, like higher education, will struggle to maintain a value proposition that no longer makes sense when we can't stand shoulder to shoulder. And the pandemic has accelerated deeper trends in government and society, exposing a widening gap between our vision of America as a land of opportunity, and the troubling realities of our declining wellbeing.Combining his signature humor and brash style with sharp business insights and the occasional dose of righteous anger, Galloway offers both warning and hope in equal measure. As he writes, Our commonwealth didn't just happen, it was shaped. We chose this path--no trend is permanent and can't be made worse or corrected.
