Free Download Les Fureurs de la terre de Claude Allègre Français | 30 septembre 1987 | ISBN: 2738100163 | True EPUB | 247 pages | 13.4 MB La science moderne envoie les hommes dans l'espace, mais peut-elle nous prémunir contre les tremblements de terre et les éruptions volcaniques ? Certes, la compréhension de ces phénomènes a fait, ces dernières années, des progrès décisifs, mais la prise en compte récente du coût économique de l'évacuation des zones à risques laisse à nouveau planer la menace de séismes destructeurs...  Free Download Les Enfants du Paradis (BFI Film Classics) by Jill Forbes English | February 26, 1997 | ISBN: 0851703658 | True EPUB | 78 pages | 7.6 MB Les Enfants du paradis, a magnificent picaresque saga of Parisian street life and popular culture, has been called the greatest film ever made. Completed during the Occupation, it nevertheless boasted the largest set ever to have been built in a French studio, a crowd of extras and, under the direction of Marcel Carné, some of the most accomplished technicians and actors available (including Arletty and Jean-Louis Barrault as the central couple doomed to remain apart).  Free Download Lernen lernen: Bildung und Erziehung nach Pisa By Peter Struck 2009 | 126 Pages | ISBN: 3896782975 | EPUB | 1 MB Im Jahr 2000 ereilte Deutschland der berühmt-berüchtigte PISA-Schock. Doch schon zuvor und auch danach haben internationale Vergleichsstudien den Deutschen bescheinigt, dass sie keine guten Schulen hätten. Die Folge war, dass in keinem Land der Welt so viel über Erziehung und Bildung geredet wurde wie in Deutschland, in keinem anderen sich aber auch so wenig bewegte. Inzwischen ist das allerdings anders: Die deutschen Schulen haben sich gewandelt in Richtung von mehr Erziehungs- und Bildungseffizienz. Klar ist aber auch, dass eine Schule keine pädagogische Insel ist, sondern dass sie sich im Umfeld des gesellschaftlichen und des familiären Wandels behaupten muss. Bildung ist also nicht unabhängig vom erzieherischen Rahmen zu sehen.Der renommierte Erziehungswissenschaftler Peter Struck bezieht in diesem Buch Stellung zu wichtigen aktuellen Fragen und Trends der Erziehungs- und Bildungsdebatte in Deutschland.  Free Download Leonardo's Anatomical Drawings (Dover Fine Art, History of Art) by Leonardo da Vinci English | December 17, 2004 | ISBN: 0486438627 | True EPUB | 64 pages | 20.9 MB "It is a miracle that any one man should have observed, read, and written down so much in a single lifetime." - Kenneth Clark, art historian and Leonardo da Vinci biographer  Free Download Leonardo da Vinci's Giant Crossbow by Matthew Landrus English | PDF | 2010 | 187 Pages | ISBN : 354068915X | 154.3 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.  Free Download Leibniz' Doctrine of Necessary Truth By Margaret Dauler Wilson 2019 | 152 Pages | ISBN: 0367334623 | EPUB | 1 MB Originally published in 1990. This study was first written in 1965 when interest in Leibniz was intensifying. The book looks in detail at the doctrine of necessity - that necessary truths are those derivable from the principle of identity by the substitution of definitions. It first considers views of philosophic predecessors, relating Leibniz' doctrine to Aristotle and Hobbes among others. The second section examines the conflict between his reductionistic and formalistic views and the opposing intuitionism and anti-reductionism of Descartes and Locke. The author critically examines the theory of necessity, including Leibniz's arguments against the views of Hobbes and Locke, concluding with distinctions between necessary and contingent truths.  Free Download Legalität und Legitimität By Schmitt, Carl 2012 | 99 Pages | ISBN: 3428138449 | PDF | 1 MB Wenn zu Beginn dieser Darlegungen über Legalität und Legitimität die heutige innerstaatliche Lage Deutschlands staats- und verfassungsrechtlich als Zusammenbruch des parlamentarischen Gesetzgebungsstaates gekennzeichnet wird, so ist das nur als eine zusammenfassende, kurze, fachwissenschaftliche Formel gemeint. Optimistische oder pessimistische Vermutungen und Prognosen interessieren hier nicht; von Krisen - seien es nun biologische, medizinische oder ökonomische Krisen, Nachkriegskrisen, Vertrauenskrisen, Gesundungskrisen, Pubertätskrisen, Schrumpfungskrisen oder was immer - soll ebenfalls nicht gesprochen werden. Um die ganze Problematik des heutigen Legalitätsbegriffes, des ihm zugehörigen parlamentarischen Gesetzgebungsstaates und des aus der Vorkriegszeit überlieferten Rechtspositivismus richtig zu verstehen, bedarf es staats- und verfassungsrechtlicher Begriffsbestimmungen, welche die gegenwärtige innerpolitische Lage in ihren staatlichen Zusammenhängen im Auge behalten.$aAus der Einleitung$z  Free Download Lectures on the Mechanical Foundations of Thermodynamics, SecondEdition by Michele Campisi English | PDF EPUB (True) | 2025 | 124 Pages | ISBN : 3031570448 | 18 MB This book provides a modern pedagogical exposition of the mechanical approach to statistical mechanics initiated by Boltzmann with his early works (1866-1871). Despite the later contribution by Helmholtz, Boltzmann himself (1884-1887), Gibbs, P. Hertz, and Einstein, the mechanical approach remained almost unknown to the modern reader, in favour of the celebrated combinatorial approach, developed by Boltzmann himself during his probabilistic turn (1876-1884). The brief constitutes an ideal continuation of a graduate course of classical mechanics and requires knowledge of basic calculus in many dimensions (including differential forms), thermodynamics, and probability theory, besides Hamiltonian mechanics. The cornerstone of the whole presentation is the ergodic hypothesis. Special attention is devoted to Massieu potentials (the Legendre transforms of the entropy) which are most natural in statistical mechanics and also allow for a more direct treatment of the topic of ensemble equivalence. In this second edition, a chapter is added that addresses the long-debated question of how the second law of thermodynamics can be reconciled with mechanics, by using modern methods of non-equilibrium statistical mechanics.  Free Download Lectures on the Geometry of Poisson Manifolds by Izu Vaisman English | PDF | 1994 | 210 Pages | ISBN : 3764350164 | 18.1 MB Everybody having even the slightest interest in analytical mechanics remembers having met there the Poisson bracket of two functions of 2n variables (pi, qi)  Free Download Lectures on Morse Homology by Augustin Banyaga , David Hurtubise English | PDF (True) | 2004 | 330 Pages | ISBN : 1402026951 | 24 MB This book is based on the lecture notes from a course we taught at Penn State University during the fall of 2002. The main goal of the course was to give a complete and detailed proof of the Morse Homology Theorem (Theo rem 7.4) at a level appropriate for second year graduate students. The course was designed for students who had a basic understanding of singular homol ogy, CW-complexes, applications of the existence and uniqueness theorem for O.D.E.s to vector fields on smooth Riemannian manifolds, and Sard's Theo rem. We would like to thank the following students for their participation in the course and their help proofreading early versions of this manuscript: James Barton, Shantanu Dave, Svetlana Krat, Viet-Trung Luu, and Chris Saunders. We would especially like to thank Chris Saunders for his dedication and en thusiasm concerning this project and the many helpful suggestions he made throughout the development of this text. We would also like to thank Bob Wells for sharing with us his extensive knowledge of CW-complexes, Morse theory, and singular homology. Chapters 3 and 6, in particular, benefited significantly from the many insightful conver sations we had with Bob Wells concerning a Morse function and its associated CW-complex. |
