L'histoire derrière l'histoire officiellement racontée

L'histoire derrière l'histoire officiellement racontée

Número de Páginas: 270

Et si l’histoire que nous connaissons n’était qu’une surface calme, dissimulant des courants bien plus profonds ? Ce livre propose une exploration exigeante et rigoureusement documentée des origines de l’humanité et des récits qui les entourent. En croisant les sciences du vivant, l’anthropologie, l’histoire, les textes anciens et la pensée africaine, il interroge les fondations mêmes de ce que nous croyons savoir. De la mélanine — molécule centrale du vivant — aux premières populations humaines, des structures génétiques aux grands bouleversements historiques, des fossiles aux mythes fondateurs, l’ouvrage met en lumière des zones laissées dans l’ombre par l’histoire officiellement racontée. Loin des discours idéologiques ou des simplifications, l'auteur confronte les sources, met en dialogue les disciplines et invite à repenser la mémoire humaine dans toute sa complexité. L’Afrique, berceau fondamental de l’humanité, y retrouve sa place : scientifique, culturelle et mémorielle. Ce livre s’adresse à celles et ceux qui ressentent que quelque chose manque au narratif dominant; à celles et ceux qui cherchent à comprendre plutôt...

Radiative Transfer in Stellar and Planetary Atmospheres

Radiative Transfer in Stellar and Planetary Atmospheres

Autor: Lucio Crivellari , Sergio Simón-díaz , María Jesús Arévalo

Número de Páginas: 251

Radiative transfer is essential for obtaining information from the spectra of astrophysical objects. This volume provides an overview of the physical and mathematical background of radiative transfer, and its applications to stellar and planetary atmospheres. It covers the phenomenology and physics of early-type and late-type stars, as well as ultra-cool dwarf stars and extrasolar planets. Importantly, it provides a bridge between classical radiative transfer and stellar atmosphere modelling and novel approaches, from both theoretical and computational standpoints. With new fields of application and a dramatic improvement in both observational and computational facilities, it also discusses the future outlook for the field. Chapters are written by eminent researchers from across the astronomical disciplines where radiative transfer is employed. Using the most recent observations, this is a go-to resource for graduate students and researchers in astrophysics.

Life in the Cosmos

Life in the Cosmos

Autor: Manasvi Lingam , Abraham Loeb

Número de Páginas: 1089

A rigorous and scientific analysis of the myriad possibilities of life beyond our planet. ÒAre we alone in the universe?Ó This tantalizing question has captivated humanity over millennia, but seldom has it been approached rigorously. Today the search for signatures of extraterrestrial life and intelligence has become a rapidly advancing scientific endeavor. Missions to Mars, Europa, and Titan seek evidence of life. Laboratory experiments have made great strides in creating synthetic life, deepening our understanding of conditions that give rise to living entities. And on the horizon are sophisticated telescopes to detect and characterize exoplanets most likely to harbor life. Life in the Cosmos offers a thorough overview of the burgeoning field of astrobiology, including the salient methods and paradigms involved in the search for extraterrestrial life and intelligence. Manasvi Lingam and Abraham Loeb tackle three areas of interest in hunting for life Òout thereÓ: first, the pathways by which life originates and evolves; second, planetary and stellar factors that affect the habitability of worlds, with an eye on the biomarkers that may reveal the presence of microbial life;...

Advanced Solar Polarimetry

Advanced Solar Polarimetry

Autor: National Solar Observatory/sacramento Peak. Summer Workshop

Número de Páginas: 666

Annotation This proceedings volume of the September 2000 workshop presents recent developments in spectropolarimetry and the measurement of solar magnetic fields using the Zeeman and Hanle effects. The 67 papers address new instrumentation for telescopes, weak polarization and coronal magnetic fields, infrared polarimetry and the physics of active regions, magnetohydrodynamic (MHD) simulations, high resolutions polarimetry and the physics of flux tubes, and the analysis of Stokes profiles.

The Solar Dynamics Observatory

Autor: Phillip Chamberlin , William Dean Pesnell , Barbara Thompson

Número de Páginas: 405

This volume is dedicated to the Solar Dynamics Observatory (SDO), which was launched 11 February 2010. The articles focus on the spacecraft and its instruments: the Atmospheric Imaging Assembly (AIA), the Extreme Ultraviolet Variability Experiment (EVE), and the Helioseismic and Magnetic Imager (HMI). Articles within also describe calibration results and data processing pipelines that are critical to understanding the data and products, concluding with a description of the successful Education and Public Outreach activities. This book is geared towards anyone interested in using the unprecedented data from SDO, whether for fundamental heliophysics research, space weather modeling and forecasting, or educational purposes. Previously published in Solar Physics journal, Vol. 275/1-2, 2012. Selected articles in this book are published open access under a CC BY-NC 2.5 license at link.springer.com.
