From Wired senior writer Andy Greenberg comes the true story of the desperate hunt to identify and track an elite…
team of Russian agents bent on digital sabotage In 2014, the world witnessed the start of a mysterious series of cyberattacks. Targeting American utility companies, NATO, and electric grids in Eastern Europe, the strikes grew ever more brazen, including the first-ever blackouts triggered by hackers. The attacks culminated in the summer of 2017, when the malware known as NotPetya was unleashed, penetrating, disrupting, and paralyzing some of the world's largest companies-from drug manufacturers to software developers to shipping companies. At the attack's epicenter in Ukraine, ATMs froze. The railway and postal systems shut down. Hospitals went dark. NotPetya spread around the world, inflicting an unprecedented ten billion dollars in damage-the largest, most devastating cyberattack the world had ever seen. The hackers behind these attacks are quickly gaining a reputation as the most dangerous team of cyberwarriors in history: Sandworm. Working in the service of Russia's military intelligence agency, they represent a persistent, highly skilled, state-sponsored force, one whose talents are matched by their willingness to launch broad, unrestrained attacks on the most critical infrastructure of their adversaries. They target government and private sector, military and civilians alike. A chilling, globe-spanning detective story, Sandworm considers the danger this force poses to our national stability and security. As the Kremlin's role in meddling in the 2016 election, manipulating foreign governments, and sparking chaos comes into greater focus, Sandworm exposes the realities not just of Russia's global digital offensive, but of an era where warfare ceases to be waged on the battlefield. It reveals how the line between digital and physical conflict, between wartime and peacetime, have begun to blur-with world-shaking implications.Par Sean Carroll. 2019
Caltech physicist and New York Times bestselling author Sean Carroll shows that there are multiple copies of you. And everyone…
else. Really. Something Deeply Hidden begins with the news that physics is in a crisis. Quantum mechanics underlies all of modern physics but major gaps in the theory have been ignored since 1927. Science popularizers keep telling us how weird it is, how contradictory, how impossible it is to understand. Academics discourage students from working on the "dead end" of quantum foundations. Putting his professional reputation on the line, Carroll says that crisis can now come to an end. We just have to accept that there is more than one of us in the universe. There are many, many Sean Carrolls. Many of every one of us. The Many Worlds Theory of quantum behavior says that every time there is a quantum event, a world splits off with everything in it the same, except in that other world the quantum event didn't happen. Since the beginning of the universe about fourteen billion years ago, this has happened about ten to the tenth to the one-hundredth power times. Step-by-step in Carroll's uniquely lucid way, he sets out the major objections to this utterly mind-blowing notion until his case is inescapably established. The holy grail of modern physics is reconciling quantum mechanics with Einstein's general relativity- his theory of curved spacetime. Carroll argues that our refusal to face up to the mysteries of quantum mechanics has blinded us, and that spacetime and gravity naturally emerge from a deeper reality called the wave function. No book for a popular audience has attempted to make this radical argument. We're on the threshold of a new way of understanding the cosmos.In this explosive memoir, a political consultant and technology whistleblower reveals the disturbing truth about the multi-billion-dollar data industry, revealing…
to the public how companies are getting richer using our personal information and exposing how Cambridge Analytica exploited weaknesses in privacy laws to help elect Donald Trump-and how this could easily happen again in the 2020 presidential election. When Brittany Kaiser joined Cambridge Analytica-the UK-based political consulting firm funded by conservative billionaire and Donald Trump patron Robert Mercer-she was an idealistic young professional working on her fourth degree in human rights law and international relations. A veteran of Barack Obama's 2008 campaign, Kaiser's goal was to utilize data for humanitarian purposes, most notably to prevent genocide and human rights abuses. But her experience inside Cambridge Analytica opened her eyes to the tremendous risks that this unregulated industry poses to privacy and democracy. Targeted is Kaiser's eyewitness chronicle of the dramatic and disturbing story of the rise and fall of Cambridge Analytica. She reveals to the public how Facebook's lax policies and lack of sufficient national laws allowed voters to be manipulated in both Britain and the United States, where personal data was weaponized to spread fake news and racist messaging during the Brexit vote and the 2016 election. But the damage isn't done Kaiser warns; the 2020 election can be compromised as well if we continue to do nothing. In the aftermath of the U.S. election, as she became aware of the horrifying reality of what Cambridge Analytica had done in support of Donald Trump, Kaiser made the difficult choice to expose the truth. Risking her career, relationships, and personal safety, she told authorities about the data industry's unethical business practices, eventually testifying before Parliament about the company's Brexit efforts and helping Special Counsel Robert Mueller's investigation into Russian interference in the 2016 election, alongside at least 10 other international investigations. Packed with never-before-publicly-told stories and insights, Targeted goes inside the secretive meetings with Trump campaign personnel and details the promises Cambridge Analytica made to win. Throughout, Kaiser makes the case for regulation, arguing that legal oversight of the data industry is not only justifiable but essential to ensuring the long-term safety of our democracy.Par Diana Graber. 2019

1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here-and billions of miles from home.Par Steven Guilbeault. 2019

aborde les précieux avantages que procure déjà l'IA à nos sociétés, notamment dans les domaines de l'énergie, des transports et de la santé, ainsi que les progrès à venir. La brute s'intéresse aux aspects les plus inquiétants du développement de l'IA : l'instauration du système de crédit social en Chine, la déstabilisation de la démocratie libérale, les armes autonomes létales, etc. Finalement, Le truand examine certains aspects plus ambigus de cette technologie, ni tout à fait bonne ni tout à fait mauvaise, notamment la dictature des likes et les diverses transformations qui touchent le monde du travail.

comment approcher une façon de penser et de créer à nulle autre pareille ? Étienne Klein est parti sur ses traces, il s'est attaché aux époques et aux villes où le destin d'Einstein a basculé : Aarau où, à seize ans, Einstein se demande ce qu'il se passerait s'il chevauchait un rayon de lumière ; Zurich, où il devient ingénieur en 1901 et se passionne pour la physique expérimentale ; Berne où, entre mars et septembre 1905, il publie cinq articles, dont celui sur la relativité restreinte qui révolutionnera les relations de l'espace et du temps, tout en travaillant à l'Office fédéral de la propriété intellectuelle ; Prague où, en 1912, il a l'idée que la lumière est déviée par la gravitation, esquissant ainsi la future théorie de la relativité générale. Puis Bruxelles, Anvers et, enfin, Le Coq-sur-Mer où, en 1933, Einstein se réfugie quelques mois avant de quitter l'Europe pour les États-Unis. Définitivement. "Par Yann Verdo. 2018

du violon ou fumait la pipe, et ces deux objets ne sont certes pas pour rien dans l'élaboration de ses théories. Et même si chacun de nous n'atteint pas des sphères de la pensée aussi vertigineuses que lui, l'art de penser à côté est accessible à tous. Yann Verdo le montre ici, en pratiquant la physique en amateur averti, et en nous invitant à plonger avec lui dans la physique quantique, la relativité générale et la logique. De ses rencontres imaginaires avec Einstein, Cantor et Gödel résultent une familiarité nouvelle avec ces individus hors du commun, et une compréhension profonde des grands thèmes - le temps, l'infini, la matière - qu'ils ont révolutionnésPar Crypto.

given them access to weapons of mass violence previously monopolized by the state. As Audrey Kurth Cronin explains in Power to the People, what we are seeing now is an exacerbation of an age-old trend. Over the centuries, the most surprising developments in warfare have occurred because of advances in technologies combined with changes in who can use them. Indeed, accessible innovations in destructive force have long driven new patterns of political violence. When Nobel invented dynamite and Kalashnikov designed the AK-47, each inadvertently spurred terrorist and insurgent movements that killed millions and upended the international system. That history illuminates our own situation. The twenty-first century "sharing economy" has already disrupted every institution, including the armed forces. New "open" technologies are transforming access to the means of violence. Just as importantly, higher-order functions that previously had been exclusively under state military control-mass mobilization, force projection, and systems integration-are being harnessed by non-state actors. Cronin closes by focusing on how to respond so that we both preserve the benefits of emerging technologies yet reduce the risks.Par W. Daniel Hillis. 2018
Most people are baffled by how computers work and assume that they will never understand them. What they don't realize-and…
what Daniel Hillis's short book brilliantly demonstrates-is that computers' seemingly complex operations can be broken down into a few simple parts that perform the same simple procedures over and over again. Computer wizard Hillis offers an easy-to-follow explanation of how data is processed that makes the operations of a computer seem as straightforward as those of a bicycle.Avoiding technobabble or discussions of advanced hardware, the lucid explanations and colorful anecdotes in The Pattern on the Stonego straight to the heart of what computers really do. Hillis proceeds from an outline of basic logic to clear descriptions of programming languages, algorithms, and memory. He then takes readers in simple steps up to the most exciting developments in computing today-quantum computing, parallel computing, neural networks, and self-organizing systems.Written clearly and succinctly by one of the world's leading computer scientists, The Pattern on the Stone is an indispensable guide to understanding the workings of that most ubiquitous and important of machines: the computer.Par Eric Nuzum. 2019

over 20 million episodes. And we're only at the beginning. More and more podcasts appear every day, and more and more entrepreneurs, businesses, individuals, and distributors, like Spotify, are getting into this world. One person many people turn to for help launching their podcasts is Eric Nuzum, a veteran of NPR and Audible who's had a hand in creating and launching over 130 podcasts. And the reason is that Nuzum understands the essentials of what makes a podcast work and knows how to help creators shepherd their vision from rough idea to finished product. Make Noise brings all the wisdom, advice, practical information, and big-picture thinking that any individual or business needs to make a successful podcast. He identifies core principles-such as create empathetically, i.e., think like the audience listens, and stay focused on what's unique to you and what you have to say. He helps listeners come up with a "Ten Word Description" that will guide them throughout the creative process and then gets into how-tos-how to develop character, story, voice; how to conduct an effective interview; how to be mindful of the limitations of audio (be more like Hemingway than Faulkner). He provides the rules of storytelling, advice on how to test-drive an idea, and, when it's all ready, how to develop your audiencePar Stephen Hawking, Leonard Mlodinow. 2006
FROM ONE OF THE MOST BRILLIANT MINDS OF OUR TIME COMES A BOOK THAT CLARIFIES HIS MOST IMPORTANT IDEAS Stephen…
Hawking's worldwide bestseller A Brief History of Time remains a landmark volume in scientific writing. But for readers who have asked for a more accessible formulation of its key concepts-the nature of space and time, the role of God in creation, and the history and future of the universe-A Briefer History of Time is Professor Hawking's response. Although "briefer," this book is much more than a mere explanation of Hawking's earlier work. A Briefer History of Time both clarifies and expands on the great subjects of the original, and records the latest developments in the field-from string theory to the search for a unified theory of all the forces of physics. Thirty-seven full-color illustrations enhance the text and make A Briefer History of Time an exhilarating and must-have addition in its own right to the great literature of science and ideas.Par Stephen Hawking. 2006

all over the world. Now, in a major publishing event, Hawking returns with a lavishly illustrated sequel that unravels the mysteries of the major breakthroughs that have occurred in the years since the release of his acclaimed first book. The Universe in a Nutshell - Quantum mechanics - M-theory - General relativity - 11-dimensional supergravity - 10-dimensional membranes - Superstrings - P-branes - Black holes One of the most influential thinkers of our time, Stephen Hawking is an intellectual icon, known not only for the adventurousness of his ideas but for the clarity and wit with which he expresses them. In this new book Hawking takes us to the cutting edge of theoretical physics, where truth is often stranger than fiction, to explain in laymen's terms the principles that control our universe. Like many in the community of theoretical physicists, Professor Hawking is seeking to uncover the grail of science - the elusive Theory of Everything that lies at the heart of the cosmos. In his accessible and often playful style, he guides us on his search to uncover the secrets of the universe - from supergravity to supersymmetry, from quantum theory to M-theory, from holography to duality. He takes us to the wild frontiers of science, where superstring theory and p-branes may hold the final clue to the puzzle. And he lets us behind the scenes of one of his most exciting intellectual adventures as he seeks "to combine Einstein's General Theory of Relativity and Richard Feynman's idea of multiple histories into one complete unified theory that will describe everything that happens in the universe." With characteristic exuberance, Professor Hawking invites us to be fellow travelers on this extraordinary voyage through space-time. Copious four-color illustrations help clarify this journey into a surreal wonderland where particles, sheets, and strings move in eleven dimensions; where black holes evaporate and disappear, taking their secret with them; and where the original cosmic seed from which our own universe sprang was a tiny nut. The Universe in a Nutshell is essential reading for all of us who want to understand the universe in which we live. Like its companion volume, A Brief History of Time, it conveys the excitement felt within the scientific community as the secrets of the cosmos reveal themselves.

THE FIRST MAJOR WORK IN NEARLY A DECADE BY ONE OF THE WORLD'S GREAT THINKERS-A MARVELOUSLY CONCISE BOOK WITH NEW…
ANSWERS TO THE ULTIMATE QUESTIONS OF LIFE When and how did the universe begin? Why are we here? Why is there something rather than nothing? What is the nature of reality? Why are the laws of nature so finely tuned as to allow for the existence of beings like ourselves? And, finally, is the apparent "grand design" of our universe evidence of a benevolent creator who set things in motion-or does science offer another explanation? The most fundamental questions about the origins of the universe and of life itself, once the province of philosophy, now occupy the territory where scientists, philosophers, and theologians meet-if only to disagree. In their new book, Stephen Hawking and Leonard Mlodinow present the most recent scientific thinking about the mysteries of the universe, in nontechnical language marked by both brilliance and simplicity. In The Grand Design they explain that according to quantum theory, the cosmos does not have just a single existence or history, but rather that every possible history of the universe exists simultaneously. When applied to the universe as a whole, this idea calls into question the very notion of cause and effect. But the "top-down" approach to cosmology that Hawking and Mlodinow describe would say that the fact that the past takes no definite form means that we create history by observing it, rather than that history creates us. The authors further explain that we ourselves are the product of quantum fluctuations in the very early universe, and show how quantum theory predicts the "multiverse"-the idea that ours is just one of many universes that appeared spontaneously out of nothing, each with different laws of nature. Along the way Hawking and Mlodinow question the conventional concept of reality, posing a "model-dependent" theory of reality as the best we can hope to find. And they conclude with a riveting assessment of M-theory, an explanation of the laws governing us and our universe that is currently the only viable candidate for a complete "theory of everything." If confirmed, they write, it will be the unified theory that Einstein was looking for, and the ultimate triumph of human reason. A succinct, startling, and lavishly illustrated guide to discoveries that are altering our understanding and threatening some of our most cherished belief systems, The Grand Design is a book that will inform-and provoke-like no other.Par Stephen Hawking. 2013

first time, perhaps the most brilliant cosmologist of our age turns his gaze inward for a revealing look at his own life and intellectual evolution. My Brief History recounts Stephen Hawking's improbable journey, from his postwar London boyhood to his years of international acclaim and celebrity. This concise, witty, and candid account introduces listeners to a Hawking rarely glimpsed in previous books: the inquisitive schoolboy whose classmates nicknamed him Einstein; the jokester who once placed a bet with a colleague over the existence of a particular black hole; and the young husband and father struggling to gain a foothold in the world of physics and cosmology. Writing with characteristic humility and humor, Hawking opens up about the challenges that confronted him following his diagnosis of ALS at age twenty-one. Tracing his development as a thinker, he explains how the prospect of an early death urged him onward through numerous intellectual breakthroughs, and talks about the genesis of his masterpiece A Brief History of Time-one of the iconic books of the twentieth century. Clear-eyed, intimate, and wise, My Brief History opens a window for the rest of us into Hawking's personal cosmos.Par Jean-Jacques Greif. 1999

A call to action from Jane Fonda, one of the most inspiring activists of our time, urging us to wake…
up to the looming disaster of climate change and equipping us with the tools we need to join her in protest "This is the last possible moment in history when changing course can mean saving lives and species on an unimaginable scale. It's too late for moderation." In the fall of 2019, frustrated with the obvious inaction of politicians and inspired by Greta Thunberg, Naomi Klein, and student climate strikers, Jane Fonda moved to Washington, D.C., to lead weekly climate change demonstrations on Capitol Hill. On October 11, she launched Fire Drill Fridays, and has since led thousands of people in nonviolent civil disobedience, risking arrest to protest for action. In What Can I Do? , Fonda weaves her deeply personal journey as an activist alongside conversations with and speeches by leading climate scientists and inspiring community organizers, and dives deep into the issues, such as water, migration, and human rights, to emphasize what is at stake. Most significantly, Fonda equips us all with the tools we need to join her in protest, so that everyone can work to combat the climate crisis. No stranger to protest, Fonda's life has been famously shaped by activism. And now she is once again galvanizing the public to take to the streets. Many are already aware of the looming disaster of climate change and realize that a moral responsibility rests on our shoulders. In 2019, we saw atmospheric concentrations of greenhouse gases hit the highest level ever recorded in human history, and our window of opportunity to act is quickly closing. We are facing a climate crisis, but we're also facing an empathy crisis and an inequality crisis; the surge of protests over police violence against black Americans has once again highlighted the links between racism and environmental degradation in our country. It isn't only earth's life-support systems that are unraveling. So too is our social fabric. This is going to take an all-out war on drilling and fracking and deregulation and racism and misogyny and colonialism and despair all at the same time. As Annie Leonard, executive director of Greenpeace USA and Fonda's partner in developing Fire Drill Fridays, has declared, "Change is inevitable; by design, or by disaster." Together, we can commandeer change for the positive—but it will require collective actions taken by social movements on an unprecedented scale. The problems we face now require every one of us to join the fight. The fight for not only our immediate future, but for the future of generations to come. *This audiobook program includes a PDF of photographs and graphs. 100% of the author's net proceeds from What Can I Do ? will go to Greenpeace
