The measurement of time : time, frequency and the atomic clock by Claude Audoin( Book )

11 editions published between 2001 and 2006 in English and held by 365 WorldCat member libraries worldwide

"The book will be ideal as an introduction for graduate students or researchers entering the fields of time and frequency metrology and precise astronomical observation. It will also be useful as a reference for scientists working in these and other applied areas, such as geophysics, atomic physics, astronomy and telecommunications. General readers with a background in science should also find this a fascinating book."--Jacket

Les systèmes de navigations par satellite tels que GPS ou le futur système européen Galileo offrent un éventail impressionnant de possibilités nouvelles aussi bien au grand public qu'aux professionnels (navigateurs, topographes ...). L'évolution du niveau des mers est un paramètre-clé du changement climatique, tant pour sa compréhension que pour son impact sociétal. L'exploration planétaire par les missions spatiales produit un nombre croissant de résultats pour la connaissance de notre système solaire. La vérification et l'amélioration des théories de la gravitation sont actuellement des activités importantes de la physique fondamentale. Un facteur commun est sous-jacent à tous ces constats : le rôle crucial des références de temps et d'espace. C'est l'ambition de cet ouvrage que d'offrir une brève encyclopédie sur ce domaine. Partant d'un panorama historique qui insiste sur l'évolution des concepts, il aboutit à une présentation de l'état actuel, illustrant le rôle majeur des techniques spatiales, et surtout des horloges atomiques qui placent le temps comme élément fondamental sur le plan métrologique.

The IUGG Upper Mantle Committee has stated that the hypothesis of continental drift envisages horizontal displacements of the continents over th- sands of kilometers, and that it is a principal objective of the Upper Mantle Project to prove whether or not continental drift has occurred. The origin of the hypothesis may be traced to the close similarity in outlines of the coasts on the two sides of the Atlantic Ocean. The theory that the eastern and western hemispheres are drifting apart was expounded in particular by A. Wegener. Modern geophysical theories seek to explain paleomagnetic observations by - suming that two things have occurred in the past: (a) large-scale polar wandering, and (b) continental drift. A direct confirmation of drift, if it exists, is greatly desired. Attempts have been made to prove that continental drift has occurred from - served changes in latitude and longitude. It was thought by some, in fact, that such changes had been detected
