Jean LefortPourquoi le calcul des longitudes n'a-t-il pu être maîtrisé qu'après l'invention du chronomètre de marine en 1735, alors que celui des latitudes l'était déjà 1600 ans plus tôt ? Cet ouvrag

There is without question immense general and academic interest in the Islamic world at present. After the attacks on New York and Washington in September 2001 and the wars on Afghanistan and Iraq, 'Islamic Fundamentalism' has come to be seen by many people in the West as the primary threat to world peace. Although not all scholars would agree that we are heading for a 'Clash on Civilizations' between Islam and the West, few would dispute that Islamic and Western cultures have evolved very differently. It is impossible to have a real understanding of current Islam without first understanding the historical perspective. Malise Ruthven, author of many acclaimed works on Islam and the Islamic world, including Fundamentalism , A Fury of God: The Islamist Attack on America , and Islam: A Very Short Introduction , and a regular commentator in the print and broadcast media, is ideally placed to provide this perspective. Thoroughly researched and very well written, the Historical Atlas of the Islamic World is concise, accessible, and authoritative. It spans the period from pre-Islamic late antiquity to the present day, incorporating recent patterns of emigration from Muslim-majority countries and the independence of the post-Soviet Muslim states of Central Asia. The maps use the latest design techniques to indicate the shifting nature of frontiers and population densities. In addition to historical maps of the changing internal and external boundaries of the Islamic World, there are maps showing the principle trade routes through which ideas and customs as well as goods were spread. Other maps and charts trace the rise and fall of Islamic dynasties and religious sects, the structure of cities, the distribution of minerals and water resources, agricultural patterns, and archaeological sites. The maps are accompanied by short essays on a wide range of themes, among them: all the countries and regions with Muslim majorities; institutions such as Shari'a (divine law) and fiqh (jurisprudence); philosophy; architecture; costume; the Muslim city; trade, commerce and manufacturing; the decorative arts; marriage and family life; tribal distributions; kinship, and dynastic power; mosque architecture, ritual, and devotional practices; Sufism; modernist and reformist trends; European domination of the Islamic world; Islamic political movments; and oil.

Combining the data from 18 of the most advanced Earth satellites ever built, NASA has constructed the most detailed global portrait of our planet ever created. The Complete Earth reproduces this photomap in its entirety and at full-resolution, living up to its title by revealing the whole planet, cloud-free, at a resolution of 500m to every pixel, or 90 miles to every inch. At this scale we can trace the Amazon from Andean headwaters to Atlantic mouth, or explore the trackless sand seas of the Sahara, or follow the corrugated ridges of hills and mountains that mark the front line of India''s tectonic assault on Eurasia as if we were in low-Earth orbit. These images are supplemented by a wealth of even higher resolution satellite imagery that zooms in on noteworthy features - from volcanoes to cities, river deltas to glaciers. In addition, 12 double-page-spreads chart one year in the life of our planet as they follow the ebb and flow of the seasons across the globe: we watch snow fall in the North as it melts in the South, and desert lands bloom and fade as the rains come and go. Accompanying the images, a brief but informative text explores the history of each landscape, explaining the how and when of its mountain ranges, deserts and plains.

Salmones, nutrias, desmanes, anguilas, mirlos acuáticos, tritones, truchas, libélulas, ranas, alisedas, saucedas... Los ríos de Asturias se encuentran entre los mejor conservados de toda España, albergando una rica fauna y flora cuya conservación debe ser prioritaria. Este libro nos acerca a la naturaleza y la vida asociada a nuestros ríos, pretendiendo que el lector los vea como algo vivo y no como simples cursos de agua. Con una cuidada selección de imágenes, el autor recorre nuestros ríos desde su nacimiento hasta su llegada al mar, describiendo los vegetales y animales que ocupan cada tramo, las relaciones entre ellos y algunos de sus curiosos ciclos vitales. La divulgación y conocimiento de sus valores contribuirá a una sensibilización que esperamos ayude a que nuestros ríos sigan siempre vivos.
