Avant d'être un concept, la Terre fut une donnée : d'abord, la Terre nourricière – autrement dit, la « terre végétale » –, puis, la Terre où l'homme vit, par opposition à la mer, c'est-à-dire les terres émergées. Tout naturellement, cette Terre, siège de l'humanité, était le centre du monde, qui...

L'observation à l'œil nu d'un ciel constellé d'étoiles montre que celles-ci ne sont pas réparties au hasard: elles tendent à se regrouper en une longue écharpe laiteuse qui parcourt la voûte céleste d'un bord à l'autre de l'horizon, et que nos ancêtres ont appelée la Voie lactée. Les philosophes ...

À l'instar de Jupiter, Saturne constitue, avec son cortège de satellites, un système solaire en miniature mais, surtout, offre le spectacle somptueux de ses anneaux, découverts dès 1610 par Galilée et interprétés en tant qu'anneaux par Christiaan Huygens en 1656. Saturne a été exploré à quatre ...

Professionally converted for accurate flowing-text e-book format reproduction, this unique and informative history covers the political, administrative, and social aspects of the Wallops Station from 1957 to 1966. This period began with the launch of the Soviet Union's Sputnik 2, continued through...

In volume three, students will look over Albert Einstein's shoulder as he and his colleagues develop a new kind of physics. It leads in two directions: to knowledge of the vast universe and its future (insights build on Einstein's theories of relativity), and to an understanding of the astonishingly...

Though astrophysicists have developed a theoretical framework for understanding how the first stars and galaxies formed, only now are we able to begin testing those theories with actual observations of the very distant, early universe. We are entering a new and exciting era of discovery that will...

Dwarf planets (which were formerly called asteroids except for the planet Pluto), and the smaller Solar System bodies still called asteroids today, are making front page news, particularly those that are newly discovered and those that might present a hazard to life on Earth by impacting our planet....

This popular science book offers a glimpse into a plethora of extreme cosmic phenomena in which the theories of modern physics, particularly quantum mechanics and general relativity, play a key role. Despite their vastly different appearances, these cosmic phenomena have much in common: they are all...

Using the vortex theory the author has identified a source of enormous energy at the core centre of the Earth. He calls it the Gravity Geyser. Geological evidence reveals every few thousand years devastating earth changes occur that are linked to the reversal of the Poles. The understanding of why...

This thesis highlights data from MINOS, a long-baseline accelerator neutrino experiment, and details one of the most sensitive searches for the sterile neutrino ever made. Further, it presents a new analysis paradigm to enable this measurement and a comprehensive study of the myriad systematic uncertainties...

The book gives a glimpse of the development of the earth observation cameras in India and provides insights into the technological innovations and the leadership foresight which placed India at par with achievements elsewhere in the world, in this area. The book also covers some aspects of the management...

Beginning with the famous Olber's paradox, paradoxes such as the missing mass, dark energy, baryon to photon ratio and cosmic zero-point energy are examined in detail. The Heisenberg–Lemaitre's units, based on the total enormous but finite mass of the Universe, are introduced and rigorous solutions...

In response to the new information gained about the Solar System from recent space probes and space telescopes, the experienced science author Dr. John Wilkinson presents the state-of-the art knowledge on the Sun, solar system planets and small solar system objects like comets and asteroids. He also...

Information collected by satellites recently sent by the USA, the European Space Agency, Japan, Germany, the United Kingdom, and Russia to monitor the Sun has changed our knowledge and understanding of the Sun, particularly its effect on Earth. This book presents these findings in a way that will...
