The world's most entertaining and useless self-help guide, from the brilliant mind behind the wildly popular webcomic xkcd and the…
#1 New York Times bestsellers What If? and Thing Explainer For any task you might want to do, there's a right way, a wrong way, and a way so monumentally bad that no one would ever try it. How To is a guide to the third kind of approach. It's full of highly impractical advice for everything from landing a plane to digging a hole. Bestselling author and cartoonist Randall Munroe explains how to predict the weather by analyzing the pixels of your Facebook photos. He teaches you how to tell if you're a baby boomer or a 90's kid by measuring the radioactivity of your teeth. He offers tips for taking a selfie with a telescope, crossing a river by boiling it, and getting to your appointments on time by destroying the Moon. And if you want to get rid of the book once you're done with it, he walks you through your options for proper disposal, including dissolving it in the ocean, converting it to a vapor, using tectonic plates to subduct it into the Earth's mantle, or launching it into the Sun. By exploring the most complicated ways to do simple tasks, Munroe doesn't just make things difficult for himself and his readers. As he did so brilliantly in What If?, Munroe invites us to explore the most absurd reaches of the possible. Full of clever infographics and amusing illustrations, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.Something Deeply Hidden: Quantum Worlds and the Emergence of Spacetime

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.An astonishing exploration of planet formation and the origins of life by one of the world's most innovative planetary geologists.In…
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.Evaluates a broad range of food and consumer products in terms of the acute and chronic health hazards that they…

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.

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 révolutionnésTalk Money to Me: Save Well, Spend Some, and Feel Good About Your Money

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.The Universe in a Nutshell

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.My Brief History

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.Tout est relatif, comme dit Einstein (Médium)

Par Jane Fonda. 2020
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 GreenpeaceThe smallest lights in the universe: A memoir

connection on this planet, even as she searches our galaxy for another Earth. &“Sara Seager&’s exploration of outer and inner space makes for a stunningly original memoir.&”—Abraham Verghese, author of Cutting for Stone Sara Seager has always been in love with the stars: so many lights in the sky, so much possibility. Now a pioneering planetary scientist, she searches for exoplanets—especially that distant, elusive world that sustains life. But with the unexpected death of Seager&’s husband, the purpose of her own life becomes hard for her to see. Suddenly, at forty, she is a widow and the single mother of two young boys. For the first time, she feels alone in the universe. As she struggles to navigate her life after loss, Seager takes solace in the alien beauty of exoplanets and the technical challenges of exploration. At the same time, she discovers earthbound connections that feel every bit as wondrous, when strangers and loved ones alike reach out to her across the space of her grief. Among them are the Widows of Concord, a group of women offering advice on everything from home maintenance to dating, and her beloved sons, Max and Alex. Most unexpected of all, there is another kind of one-in-a-billion match, not in the stars but here at home.

A NEW YORK TIMES NOTABLE BOOK OF 2020 NAMED A BEST BOOK OF THE YEAR BY * THE WASHINGTON POST…
* THE ECONOMIST * NEW SCIENTIST * PUBLISHERS WEEKLY * THE GUARDIAN "A thrilling tour of potential cosmic doomsdays....Mack's infectious enthusiasm for communicating the finer points of cosmological doom elevates The End of Everything over any other book on the topic. " — The Wall Street Journal " I found it helpful—not reassuring, certainly, but mind-expanding—to be reminded of our place in a vast cosmos." —James Gleick, The New York Times Book Review From one of the most dynamic rising stars in astrophysics, an accessible and eye-opening look at five ways the universe could end, and the mind-blowing lessons each scenario reveals about the most important concepts in cosmology. We know the universe had a beginning. With the Big Bang, it expanded from a state of unimaginable density to an all-encompassing cosmic fireball to a simmering fluid of matter and energy, laying down the seeds for everything from black holes to one rocky planet orbiting a star near the edge of a spiral galaxy that happened to develop life as we know it. But what happens to the universe at the end of the story? And what does it mean for us now? Dr. Katie Mack has been contemplating these questions since she was a young student, when her astronomy professor informed her the universe could end at any moment, in an instant. This revelation set her on the path toward theoretical astrophysics. Now, with lively wit and humor, she takes us on a mind-bending tour through five of the cosmos's possible finales: the Big Crunch, Heat Death, the Big Rip, Vacuum Decay (the one that could happen at any moment!), and the Bounce. Guiding us through cutting-edge science and major concepts in quantum mechanics, cosmology, string theory, and much more, The End of Everything is a wildly fun, surprisingly upbeat ride to the farthest reaches of all that we know
