Discours sur l'origine de l'univers
Par Étienne Klein. 2010
" D'où vient l'univers ? Et d'ou vient qu'il y a un univers ? Irrépressiblement, ces questions se posent à…
nous. Et dès qu'un discours prétend nous éclairer, nous tendons l'oreille, avides d'entendre l'écho du tout premier signal : les accélérateurs de particules vont bientôt nous révéler l'origine de l'univers en produisant des big bang sous terre ; les données recueillies par le satellite Planck nous dévoiler le visage de Dieu ; certains disent même qu'en vertu de la loi de la gravitation l'univers a pu se créer de lui-même, à partir de rien... Le grand dévoilement ne serait donc devenu qu'une affaire d'ultimes petits pas ? Rien n'est moins sûr... Car de quoi parle la physique quand elle parle d' origine ? Qu'est-ce que les théories actuelles sont réellement en mesure de nous révéler ? À bien les examiner, les perspectives que nous offre la cosmologie contemporaine sont plus vertigineuses encore que tout ce que nous avons imaginé : l'univers a-t-il jamais commencé ? " -- 4e de couv.The quantum ten: a story of passion, tragedy, ambition and science

within us? Few of us have time to contemplate the cosmos, so Tyson brings the universe down to Earth succinctly and clearly, with sparkling wit, in digestible chapters consumable anytime and anywhere in your busy day. While waiting for your morning coffee to brew, or while waiting for the bus, the train, or the plane to arrive, "Astrophysics for people in a hurry" will reveal just what you need to be fluent and ready for the next cosmic headlines: from the Big Bang to black holes, from quarks to quantum mechanics, and from the search for planets to the search for life in the universe. Bestseller. 2017.Accessory to War: The Unspoken Alliance Between Astrophysics and the Military
Par Avis Lang, Neil DeGrasse Tyson. 2019
“Extraordinary.… A feast of history, an expert tour through thousands of years of war and conquest.” —Jennifer Carson, New York…
Times Book Review In this far-reaching foray into the millennia-long relationship between science and military power, acclaimed astrophysicist Neil deGrasse Tyson and co-author Avis Lang examine how the methods and tools of astrophysics have been enlisted in the service of war. Spanning early celestial navigation to satellite-enabled warfare, Accessory to War is a richly researched and provocative examination of the intersection of science, technology, industry, and power that will introduce Tyson’s millions of fans to yet another dimension of how the universe has shaped our lives and our world.The end of everything: (astrophysically speaking)
