This book is a compilation of the lectures for a one-semester course on gravitation at the University of Rochester. Starting from a simple description of geometry, the topics are systematically developed to the big bang theory with a simple derivation of the cosmic background temperature. Several informative examples are worked out in detail as well.

The three greatest scientific mysteries, which remain poorly understood, are the origin of the universe, the origin of life and the development of consciousness. This book describes the processes preceding the Big Bang, the creation of matter, the concentration of that matter into stars and planets, the development of simple life forms and the theory of evolution that has given higher life forms, including mankind.There are many popular and excellent science books that present various aspects of science. However, this book follows a narrow scientific pathway from the Big Bang to mankind, and d

En 1931, dans un court article dans la revue Nature, Georges Lemaître proposa que toute la matière présente dans l’univers physique provienne de la pulvérisation de l’atome primitif. Le concept de l’atome primitif fut l’embryon de la théorie du big bang, reprise par d’autres cosmologistes et savamment développée durant la seconde moitié du xxe siècle. L’hypothèse de l’atome primitif : essai de cosmogonie, une série de conférences données entre 1929 et 1945 par Georges Lemaître, fut publié en 1946. Lus aujourd’hui, les textes de ces conférences dressent un tableau de la naissance de la cosmologie moderne. L’ensemble reflète l’évolution rapide des connaissances en astronomie et en physique nucléaire durant la période mouvementée des années 1930 et 1940. De plus, le propos de Lemaître est éloquent par sa finesse pédagogique. Ce petit livre offre un exceptionnel portrait des idées en astronomie et en cosmologie et de leur évolution entre les années 1920 et 1950. Vous assisterez en le lisant à la naissance du big bang.

Bang zijn is heel gewoon. Maar niet "durven" bang zijn, dat ispas erg. Dan ben je dubbel-dubbel bang. Want niemand mag het weten. Je bent alleen met je angst. Héél erg is dat. Ik was zo'n kind.

We know the universe has a history, but does it also have a story of self-creation to tell? Yes, in Roy R. Gould's account. He offers a compelling narrative of how the universe--with no instruction other than its own laws--evolved into billions of galaxies and gave rise to life, including humans who have been trying for millennia to comprehend it. Far from being a random accident, the universe is hard at work, extracting order from chaos. Making use of the best current science, Gould turns what many assume to be true about the universe on its head. The cosmos expands inward, not outward. Gravity can drive things apart, not merely together. And the universe seems to defy entropy as it becomes more ordered, rather than the other way around. Strangest of all, the universe is exquisitely hospitable to life, despite its being constructed from undistinguished atoms and a few unexceptional rules of behavior. Universe in Creation explores whether the emergence of life, rather than being a mere cosmic afterthought, may be written into the most basic laws of nature. Offering a fresh take on what brought the world--and us--into being, Gould helps us see the universe as the master of its own creation, not tethered to a singular event but burgeoning as new space and energy continuously stream into existence. It is a very old story, as yet unfinished, with plotlines that twist and churn through infinite space and time.--
