À quelle altitude faut-il lâcher un steak pour qu'il arrive cuit au sol ? Qu'adviendrait-il de notre planète si le Soleil s'éteignait d'un coup ? Et si tous les Terriens sautaient en l'air et retombaient en même temps ? Combien de temps pourriez-vous nager dans une piscine emplie des déchets nucléaires ? Quelle puissance Yoda, le héros de la Guerre des étoiles, développe-t-il ?
Peut-on imaginer de répondre de façon sérieuse à des questions aussi loufoques ? C'est le pari de Randall Munroe qui, pour rédiger ce livre, n'a pas hésité à éplucher des montagnes de notes déclassifiées de l'armée américaine, à interviewer des ingénieurs nucléaires, à appeler 10 fois de suite sa vieille mère à la rescousse et à « googler » des animaux très très bizarres !
Le résultat ? Un bijou de vulgarisation scientifique aux comics trips hilarants, où l'auteur parvient à calculer et à expliquer l'impossible, depuis la probabilité de rencontrer votre âme soeur jusqu'aux terribles symptômes dont vous souffririez si votre ADN venait subitement à disparaître.
Bref, un remue-méninges inouï, enfin disponible en français après être longtemps resté n°1 de la liste des best-sellers du New York Times
Le guide le plus réjouissant et le plus inutile de la planète.
Dans son premier opus, Randall Munroe résolvait les questions les plus saugrenues avec toute la rigueur possible (dont l'indispensable : à quelle altitude faut-il lâcher un steak pour qu'il atterrisse cuit au sol ?).
Son nouveau défi, tout aussi hilarant, procède en sens inverse : inventer les réponses les plus délirantes aux questions de tous les jours.
Jugez plutôt !
Comment être sûr de votre année de naissance ?
En mesurant la radioactivité de vos dents...
Comment savoir s'il va faire beau demain ?
En repérant les couchers de soleil rougeâtres sur les photos en ligne...
Comment traverser une rivière à gué ?
En faisant évaporer l'eau...
Appelant à la rescousse Serena Williams (Comment abattre un drone) ou l'astronaute Chris Hadfield (Comment réussir un atterrissage d'urgence), Randall Munroe nous montre qu'il est toujours plus amusant de faire compliqué quand on peut faire simple. Un summum de la vulgarisation scientifique.
THE SUNDAY TIMES BESTSELLER From the creator of the wildly popular xkcd.com, hilarious and informative answers to important questions you probably never thought to ask. Millions visit xkcd.com each week to read Randall Munroe's iconic webcomic. Fans ask him a lot of strange questions: How fast can you hit a speed bump, driving, and live? When (if ever) did the sun go down on the British Empire? When will Facebook contain more profiles of dead people than living? How many humans would a T Rex rampaging through New York need to eat a day? In pursuit of answers, Munroe runs computer simulations, pores over stacks of declassified military research memos, solves differential equations and consults nuclear reactor operators. His responses are masterpieces of clarity and hilarity, complemented by comics. They often predict the complete annihilation of humankind, or at least a really big explosion.

Welcome (back) to the mind-blowing world of What If? Unfazed by absurdity, Randall consults the latest research on everything from swing-set physics to airplane-catapult design to clearly and concisely answer his readers'' questions. As he consistently demonstrates, you can learn a lot from examining how the world might work in very specific extreme circumstances. Filled with bonkers science, boundless curiosity, and Randall''s signature stick-figure comics, What If? 2 is sure to be another instant classic adored by inquisitive readers of all ages.

AN INSTANT #1 NEW YORK TIMES BESTSELLER How To will make you laugh as you learnWith How To , you can't help but appreciate the glorious complexity of our universe and the amazing breadth of humanity's effort to comprehend it. If you want some lightweight edification, you won't go wrong with How To . -- CNET [ How To ] has science and jokes in it, so 10/10 can recommend. --Simone Giertz The world's most entertaining and useless self-help guide from the brilliant mind behind the wildly popular webcomic xkcd and the 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 complex, excessive, and inadvisable 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 powering your house by destroying the fabric of space-time. 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 fun illustrations, How To is a delightfully mind-bending way to better understand the science and technology underlying the things we do every day.
@2@@20@From the No. 1 bestselling author of @18@What If?@19@ - the man who created xkcd and explained the laws of science with cartoons - comes a series of brilliantly simple diagrams ('blueprints' if you want to be complicated about it) that show how important things work: from the nuclear bomb to the biro. @21@@16@@20@@21@@16@It's good to know what the parts of a thing are called, but it's much more interesting to know what they do. Richard Feynman once said that if you can't explain something to a first-year student, you don't really get it. In @18@Thing Explainer,@19@ Randall Munroe takes a quantum leap past this: he explains things using only drawings and a vocabulary of just our 1,000 (or the ten hundred) most common words.@3@@2@Many of the things we use every day - like our food-heating radio boxes ('microwaves'), our very tall roads ('bridges'), and our computer rooms ('datacentres') - are strange to us. So are the other worlds around our sun (the solar system), the big flat rocks we live on (tectonic plates), and even the stuff inside us (cells). Where do these things come from? How do they work? What do they look like if you open them up? And what would happen if we heated them up, cooled them down, pointed them in a different direction, or pressed this button?@3@@2@In @18@Thing Explainer,@19@ Munroe gives us the answers to these questions and many, many more. Funny, interesting, and always understandable, this book is for anyone -- age 5 to 105 -- who has ever wondered how things work, and why.@3@
