Pas une année sans que les prédictions des physiciens ne soient vérifiées, de l'existence du boson de Higgs à celle des ondes gravitationnelles. Mais cette victoire cache pourtant une surprenante vérité:nous ne savons rien (ou presque)!Des exemples? La composition de 95% de l'Univers reste une énigme, tout comme ce qu'il s'est vraiment passé durant le Big Bang. Et pourquoi est-il impossible d'aller plus vite que la lumière? Quelle est l'origine des rayons cosmiques qui bombardent la Terre en permanence? Mystère!Non content d'exposer avec la plus grande clarté le peu que nous savons déjà sur l'infiniment petit et l'infiniment grand, cet ouvrage fait le point sur les grands défis lancés à la science. Il reste tant à découvrir... et c'est heureux!
Delightful, funny, and yet rigorous and intelligent: only Jorge and Daniel can reach this exquisite balance
In our small corner of the universe, we know how some matter behaves most of the time and what even less of it looks like, and we have some good guesses about where it all came from. But we really have no clue what's going on. In fact, we don't know what about 95% of the universe is made of. So what happens when a cartoonist and a physicist walk into this strange, mostly unknown universe? Jorge Cham and Daniel Whiteson gleefully explore the biggest unknowns, why these things are still mysteries, and what a lot of smart people are doing to figure out the answers (or at least ask the right questions). While they're at it, they helpfully demystify many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humour and delight, they invite us to see the universe as a vast expanse of mostly uncharted territory that's still ours to explore. This is a book for fans of Brian Cox and What If . This highly entertaining highly illustrated book is perfect for anyone who's curious about all the great mysteries physicists are going to solve next.
Prepare to learn everything we still dont know about our strange and mysterious universe. Humanity's understanding of the physical world is full of gaps. Not tiny little gaps you can safely ignore --there are huge yawning voids in our basic notions of how the world works. PHD Comics creator Jorge Cham and particle physicist Daniel Whiteson have teamed up to explore everything we don't know about the universe: the enormous holes in our knowledge of the cosmos. Armed with their popular infographics, cartoons, and unusually entertaining and lucid explanations of science, they give us the best answers currently available for a lot of questions that are still perplexing scientists, including: * Why does the universe have a speed limit? * Why aren't we all made of antimatter? * What (or who) is attacking Earth with tiny, superfast particles? * What is dark matter, and why does it keep ignoring us? It turns out the universe is full of weird things that don't make any sense. But Cham and Whiteson make a compelling case that the questions we can't answer are as interesting as the ones we can. This fully illustrated introduction to the biggest mysteries in physics also helpfully demystifies many complicated things we do know about, from quarks and neutrinos to gravitational waves and exploding black holes. With equal doses of humor and delight, Cham and Whiteson invite us to see the universe as a possibly boundless expanse of uncharted territory that's still ours to explore.
