Electric Currents in Geospace and Beyond

Electric currents are fundamental to the structure and dynamics of space plasmas, including our own near-Earth space environment, or “geospace.”This volume takes an integrated approach to the subject of electric currents by incorporating their phenomenology and physics for many regions in one volume. It covers a broad range of topics from the pioneers of electric currents in outer space, to measurement and analysis techniques, and th...

La matière noire, clé de l'univers ?

Une référence pour tous les passionnés de cosmologie ! Si ces dernières années de nombreuses découvertes ont permis de mieux connaître notre Univers, 95 % de son contenu, constitué de matière et d énergie noires, nous est encore aujourd hui totalement inconnu. Quelle est la nature de cette matière noire, de ces particules exotiques, sans lesquelles ne pourraient se former les galaxies ? L ouvrage, rédigé par Françoise Combes astrophy...

Satellite Altimetry Over Oceans and Land Surfaces

Satellite remote sensing, in particular by radar altimetry, is a crucial technique for observations of the ocean surface and of many aspects of land surfaces, and of paramount importance for climate and environmental studies. This book provides a state-of-the-art overview of the satellite altimetry techniques and related missions, and reviews the most-up-to date applications to ocean dynamics and sea level. It also discusses related ...

Current Issues in Cosmology

What are the current ideas describing the large-scale structure of the Universe? How do they relate to the observed facts? This book looks at both the strengths and weaknesses of the current big-bang model in explaining certain puzzling data. It arises from an international conference that brought together many of the world's leading players in cosmology. In addition to presenting individual talks, the proceedings of the resulting di...

Crossroads and Cosmologies

Christopher Fennell offers a fresh perspective on ways that the earliest enslaved Africans preserved vital aspects of their traditions and identities in the New World. He also explores similar developments among European immigrants and the interactions of both groups with Native Americans. Focusing on extant artifacts left by displaced Africans, Fennell finds that material culture and religious ritual contributed to a variety of mode...
