Science Cosmology

Un Univers en expansion - La cosmologie est l'étude de l'Univers dans son ensemble. En expansion depuis 15 milliards d'années, son histoire est jalonnée d'événements cosmiques : fabrication de la matière, génération du rayonnement cosmologique, apparition des galaxies... La cosmologie est aujourd'hui devenue une science, relativiste depuis le début du XX° siècle.Une histoire de nos nos connaissances sur l'Univers. Marc Lachièze-Rey retrace ici les grandes lignes de l'évolution des idées et des principes qui fondent nos connaissances sur l'Univers.

A wise, very old, strongly clairvoyant lady leads us on a fictional journey through an imaginary land that symbolizes the levels of conscious of the mind of Homo sapiens. Perhaps there are many universes. Perhaps there is an unlimited number of virtual realities.

An accessible look at the mysteries that lurk at the edge of the known universe and beyond. The observable universe, the part we can see with telescopes, is incredibly vast. Yet recent theories suggest that there is far more to the universe than what our instruments record - in fact, it could be infinite. Colossal flows of galaxies, large empty regions called voids, and other unexplained phenomena offer clues that our own "bubble universe" could be part of a greater realm called the multiverse.

In the early 17th century, Galileo broke free from the hold of ancient Platonic and Aristotelian philosophy. He drastically changed the framework through which we view the natural world when he asserted that we should base our theory of reality on what we can observe rather than pure thought. In the process, he invented what we would come to call science. This set the stage for all the breakthroughs that followed - from Kepler to Newton to Einstein.

Highly esteemed astrophysicist Joseph Silk explores the vast mysteries and speculations of the field of cosmology in a way that balances an accessible style for the general reader and enough technical detail for advanced students and professionals. Indeed, while the physical laws and origins of the universe can be endlessly complex, even Einstein once mused that they could be explained simply enough to be grasped by nonspecialists.

Fra tutte le teorie scientifiche, la relatività è quella che più ci affascina e ci sconcerta. Andando contro la nostra rassicurante percezione del mondo, ci costringe a prendere atto che spazio e tempo non sono due dimensioni fisse e separate, ma si contraggono e si dilatano, sfumando l'una nell'altra, fino a perdere la loro individualità. La realtà è, dunque, molto più strana di quello che appare. Tutto ciò può sembrare misterioso o comprensibile solo agli addetti ai lavori. Ma non è così.

En El universo en una caja, el profesor de cosmología Andrew Pontzen, explica de una manera clara y rigurosa qué son las simulaciones, esos códigos informáticos con los que los científicos han podido recrear el universo y profundizar en su historia, poniendo a prueba por primera vez ideas centenarias. Esta suerte de manual fundamental para amantes de la astronomía, que aún está desplegando sus capacidades, replantea lo que creemos saber sobre los agujeros negros o la materia cósmica para arrojar nuevas luces sobre nuestra realidad.

Spectroscopy, the study of the interaction between matter and electromagnetic radiation, may sound complex and esoteric, but at its heart lies a simple and profound idea: the colors of light can reveal the secrets of the universe. From the examination of distant stars to the analysis of molecules in a laboratory, spectroscopy is the key that unlocks the hidden stories encoded in light.

Seja você um entusiasta da ciência, um pensador profundo ou simplesmente alguém em busca de aventura e sabedoria, este livro promete um refúgio do cotidiano, transportando-o em uma viagem de conhecimento e inspiração.

In Into the Unknown, astrophysicist Kelsey Johnson takes us to the edge of scientific understanding about the universe: What caused the Big Bang? What happens inside black holes? Are there other dimensions? She doesn’t just celebrate what we know but rather what we don’t, and asks what it means if we never find that knowledge. Exploring the convergence of science, philosophy, and theology, Johnson argues we must reckon with possibilities—including those that may be beyond human comprehension.

Set in a revolutionary era of physics and science when a series of rapid-fire discoveries was upending our understanding of the universe, Splinters of Infinity by Mark Wolverton tells a little-known story: the tale of two of America's foremost physicists, Robert Millikan (1868-1953) and Arthur Compton (1892-1962), who found themselves locked in an intense, often deeply personal, conflict about cosmic rays.

For Irwin Shapiro, science starts with questions. This book provides a broad and entertaining survey of major scientific discoveries that have changed our views of nature and, in turn, spawned further questions. Shapiro, an award-winning scientist and beloved teacher, separates his inquiry into three parts: looking up at the universe; looking down at the earth and its fossils; and looking in at the story of life. His framework encourages listeners to view science as a detective story—to observe and question nature and natural phenomena, and to base all conclusions on scientific evidence.

An extraterrestrial colony, in some form, may already exist, just awaiting discovery. But the greatest impediment to such an important scientific discovery may not be technological, but political. No scientific endeavor can be launched without a budget, and matters of money are within the arena of politicians. Dr. Ben Bova explores some of the key players and the arguments waged in a debate of both scientific and cultural priorities.

「はじめに」より 本書で紹介する宇宙思考のポイントは、次の3つです。①宇宙において、見えるもの、そして知ることができることは、視点に依存しており、視点に限られています。

O tempo não é um conceito abstrato. É uma substância material que ocupa todo o universo e se deforma, vibra, oscila. De Newton a Einstein, de Planck ao relógio cósmico, foi protagonista de metamorfoses vertiginosas, fascinantes e monstruosas. O tempo flui? Ou está parado? E como é medido? Como a gravidade o retarda? E como os buracos negros conseguem pará-lo? Sempre vivemos no tempo, que, no entanto, não é eterno.

Vorwärts in die Vergangenheit. Weiße Löcher sind das Gegenteil von Schwarzen Löchern – sie sind vermutlich ihre Abkömmlinge. Die einen ziehen alle Materie unwiderstehlich in sich hinein, die anderen geben ihre Information wieder frei. Sie sind ein weiteres großes Rätsel der Kosmologie, und noch gibt es keinen Beweis ihrer Existenz. Einsteins Gleichungen lassen sie aber vermuten, und mit Carlo Rovellis Quantentheorie sind Weiße Löcher theoretisch darstellbar.

During the formative years of Egyptian civilization, each Cosmogony was present. Students from many regions and segments of society attended the Houses of Life, and royals regularly donated endowments for the temple's maintenance and activities. These circumstances suggest a theological harmony, suggesting that a group of religious centers must have been cohesive despite their distinctive teachings and practices. Regardless of time or place in popularity, each creation myth was integral to the Egyptians' worldview.

Brian Clegg's acclaimed popular science book Inflight Science explored the science experienced on a plane flight. Interstellar Tours takes that concept and goes large. It takes the listener on a tour of our galaxy on the starship Endurance.

Forty-four science articles using the Rational Scientific Method of Inquiry. These subjects are covered in the book Curious Chain of Events, and this is the first in a series of Rational Science books.

In this special thematic anthology, we traverse the solar system, the galaxies and the multiverse, voyaging across space to explore 25 celestial objects and phenomena. Included are programmes on the universe, the sun, the moon, the stars and the planets - among them our near neighbours, Venus and Mars. Also featured are discussions on comets, asteroids and black holes, as well as eclipses, exoplanets and the mysterious, invisible substance known as 'dark matter'.
