Pour la première fois, des officiers de la DGSI (Direction Générale de la Sécurité Intérieure), racontent avec franchise leur travail sur le terrain. Nous les accompagnons dans leurs surveillances et l'espionnage de djihadistes, le recrutement de sources, le démantèlement de réseaux terroristes, la manipulation rocambolesque d'un responsable du programme d'armement syrien... Ces missions ont lieu tous les jours, sous nos yeux, mais nous ne les voyons pas.

Leonardo da Vinci's giant crossbow
Free Download Leonardo da Vinci's giant crossbow By da Vinci Leonardo; Landrus, Matthew Hayden
2010 | 180 Pages | ISBN: 354068915X | PDF | 155 MB
Although Leonardo's Giant Crossbow is one of his most popular drawings, it has been one of the least understood. "Leonardo's Giant Crossbow" offers the first in-depth account of this drawing's likely purpose and its highly resolved design. This fascinating book has a wealth of technical information about the Giant Crossbow drawing, as it's a complete study of this project, though this is as accessible to the general audience as much as it is also informative with new discoveries for the professors of engineering, technology and art. The book explores the context of Leonardo's invention with an examination of the extensive documentary evidence, a short history of the great crossbow and ballista, the first accurate translation of the text and the technical specifications, and a detailed analysis of Leonardo's design process for the crossbow, from start to finish. Dozens of preparatory drawings, along with the recent discovery of nearly invisible metal stylus preparatory incisions under the ink of the Giant Crossbow drawing, are evidence of Leonardo's intent to offer engineers and other viewers a thorough design of the massive machine. The book proposes these new discoveries with the help of a strategy that had been at the core of Leonardo's working philosophy: the proportional method. As proven with an analysis of the Giant Crossbow project, he used a consistent approach to 1/3rd proportions throughout the design and drawing process and employed this kind of proportional strategy at the start of almost every important project. Thanks to this proof of his knowledge of geometry, evidence of his studies of impetus and force, and thanks to the highly polished and complex nature of the Giant Crossbow design, a later date for the drawing is proposed in the present book, associating the drawing with his drafting capabilities around 1490-93.

Lens, Laboratory, Landscape Observing Modern Spain
Free Download Lens, Laboratory, Landscape: Observing Modern Spain By Ramón y Cajal, Santiago; Schaefer, Claudia
2014 | 239 Pages | ISBN: 143845273X | EPUB | 4 MB
An interdisciplinary study of the rise of empirical observation in the Spanish arts and sciences as the principle vehicle for acquiring knowledge about the natural world.Lens, Laboratory, Landscape focuses on competing views about the power of vision in Spain between the 1830s and the 1950s. The photographic lens, laboratory microscope, "retinal vision" of philosopher José Ortega y Gasset, and the topographical studies of Manuel de Terán are woven together in and around a European cultural milieu that gave observation primacy. For once, Spain-now bereft of its empire-was not on the outside of such debates. Whether in the laboratory, family home, darkroom, art gallery, or on the road, in Cuba or Zaragoza, Madrid or Massachusetts, Spanish artists and scientists were engaged with the social and economic power of observation at a time when the speed of modern life made observing a challenge. Claudia Schaefer brings the technologies of the eye-photograph, microscope, lens, tools for land surveying-to light as markers on the nation's touted path to modernity
