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.The Sweetness of a Simple Life: Tips for Healthier, Happier and Kinder Living from a Visionary Natural Scientist

Par Étienne Klein. 2018
" Albert Einstein, c'est l'audace intellectuelle alliée à une fraîcheur déconcertante, c'est l'imagination ardente soutenue par une obstination imperturbable. Mais…
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 révolutionnésExtreme Abilities: Amazing Human Feats and the Simple Science Behind Them

Il poursuit en décrivant la façon dont ces idées étonnantes ont ouvert la voie à une toute nouvelle interprétation des forces de l'univers, de la puissance que recèle le noyau d'un atome au comportement des corps célestes qui peuplent l'espace. -- 4e de couvThe Little Book of Cannabis: How Marijuana Can Improve Your Life
Par Amanda Siebert. 2018
A pragmatic and informative look at better living through cannabis. Cannabis. Weed. Bud. Whatever you choose to call it, it's…
been a health aid, comfort, and life-enhancer for humankind for more than three thousand years. But while cannabis is used by hundreds of millions of people around the world, more than a century of prohibition has resulted in confusion about its status: Is it healthy? Is it medicinal? Will it make you crazy? In this fun, illuminating book, cannabis journalist Amanda Siebert delves deep into the latest research to separate marijuana fact from fiction, revealing ten evidence-based ways this potent little plant can improve your life. She speaks with some of the world's top researchers, medical professionals, and consultants to answer questions such as: Can cannabis help you get a full night's sleep? Does it aid in exercise and weight loss? Can it really cure cancer? She also offers practical advice for maximizing its benefits-including easy-to-follow, step-by-step instructions for how to enjoy everything from joints to edibles, CBD oil to oral sprays-as well as examples of real people who have used cannabis to enhance their lives. This powerful plant, it turns out, could be life-changing: it can enrich any diet, slow down aging, and even spice things up in the bedroom.Power to the People: How Open Technological Innovation is Arming Tomorrow's Terrorists
Par Audrey Cronin. 2020
Never have so many possessed the means to be so lethal. The diffusion of modern technology to ordinary people has…
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.If you want to feel happier, more optimistic, more joyful, and resilient, Dr. Amen's groundbreaking new book is for you.…
We've all felt anxious, sad, traumatized, grief-stricken, stressed, angry, or hopeless at some point in life. It's perfectly normal to go through emotional crises or have periods when you feel panicked or out of sorts. It is how you respond to these challenges that will make all the difference in how you feel?not just immediately, but also in the long run. Unfortunately, many people turn to self-medicating behaviors, such as overeating, drugs, alcohol, risky sexual behavior, anger, or wasting time on mindless TV, video games, Internet surfing, or shopping. And even though these behaviors may give temporary relief from feeling bad, they usually only prolong and exacerbate the problems?or cause other, more serious ones. Is it possible to feel better?and make it last? Renowned physician, psychiatrist, brain-imaging researcher, and founder of Amen Clinics Dr. Daniel Amen understands how critical it is for you to know what will help you feel better fast, now and later. In Feel Better Fast and Make It Last, you'll discover new, powerful brain-based strategies to quickly gain control over anxiety, worry, sadness, stress and anger, strengthening your resilience and giving you joy and purpose for a lifetime.The Pattern on The Stone: The Simple Ideas That Make Computers Work (Science Masters)
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.Licensed Master Sports Nutritionist, fat-loss expert, and high-performance coach Natalie Jill has helped hundreds of thousands of people around the…

Par 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.The Universe in a Nutshell
Par Stephen Hawking. 2006
Stephen Hawking's phenomenal, multimillion-copy bestseller, A Brief History of Time, introduced the ideas of this brilliant theoretical physicist to readers…
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. From the Hardcover edition.
