Download or read book Introduction l optique written by Marie May and published by . This book was released on 1996 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: La propagation des rayons lumineux et la formation des images constituent l'objet d'étude de l'optique géométrique dont l'histoire commence avec les premiers pas de la pensée scientifique. On sait qu'il en résultera une application d'importance considérable : les instruments d'optique - à lentilles, à miroirs ou à prismes - qui permettent d'observer l'infiniment petit comme l'infiniment grand. L'œil étant le premier de ces instruments, même une étude aussi complexe que celle de la vision commence nécessairement par la description du système optique formant les images sur la rétine. Principalement destiné aux étudiants (DEUG 2e année, formation permanente et classes préparatoires scientifiques), ce manuel contient un exposé détaillé des applications de l'optique géométrique, avec les notions et les équations qui en forment le support théorique. Les systèmes centrés dans le cas de l'approximation de Gauss y font, en particulier, l'objet de développements très complets. Faisant le lien entre le rayon lumineux de l'optique géométrique et les ondes électromagnétiques, solutions des équations de Maxwell, l'auteur a voulu inscrire ce manuel dans la continuité d'un exposé d'ensemble. L'ouvrage commence donc par une présentation des conditions de validité de l'approximation et s'achève par une étude succincte des instruments d'optique ; celle-ci sera poursuivie dans un second volume consacré à l'optique ondulatoire au terme duquel l'étude des phénomènes de diffraction complètera les notions abordées ici. Chacun des quatorze chapitres du livre est suivi d'exercices et de problèmes corrigés. Un appendice sur la division harmonique complète l'ensemble.

Available in PDF, EPUB and Kindle. Book excerpt: Jonathan Crary's Techniques of the Observer provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. This analysis of the historical formation of the observer is a compelling account of the prehistory of the society of the spectacle. In Techniques of the Observer Jonathan Crary provides a dramatically new perspective on the visual culture of the nineteenth century, reassessing problems of both visual modernism and social modernity. Inverting conventional approaches, Crary considers the problem of visuality not through the study of art works and images, but by analyzing the historical construction of the observer. He insists that the problems of vision are inseparable from the operation of social power and examines how, beginning in the 1820s, the observer became the site of new discourses and practices that situated vision within the body as a physiological event. Alongside the sudden appearance of physiological optics, Crary points out, theories and models of "subjective vision" were developed that gave the observer a new autonomy and productivity while simultaneously allowing new forms of control and standardization of vision. Crary examines a range of diverse work in philosophy, in the empirical sciences, and in the elements of an emerging mass visual culture. He discusses at length the significance of optical apparatuses such as the stereoscope and of precinematic devices, detailing how they were the product of new physiological knowledge. He also shows how these forms of mass culture, usually labeled as "realist," were in fact based on abstract models of vision, and he suggests that mimetic or perspectival notions of vision and representation were initially abandoned in the first half of the nineteenth century within a variety of powerful institutions and discourses, well before the modernist painting of the 1870s and 1880s.

Download or read book The Mathematical Writings of variste Galois written by Évariste Galois and published by European Mathematical Society. This book was released on 2011 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Before he died at the age of twenty, shot in a mysterious early-morning duel at the end of May 1832, Evariste Galois created mathematics that changed the direction of algebra. This book contains English translations of almost all the Galois material. The translations are presented alongside a new transcription of the original French and are enhanced by three levels of commentary. An introduction explains the context of Galois' work, the various publications in which it appears, and the vagaries of his manuscripts. Then there is a chapter in which the five mathematical articles published in his lifetime are reprinted. After that come the testamentary letter and the first memoir (in which Galois expounded on the ideas that led to Galois Theory), which are the most famous of the manuscripts. These are followed by the second memoir and other lesser known manuscripts. This book makes available to a wide mathematical and historical readership some of the most exciting mathematics of the first half of the nineteenth century, presented in its original form. The primary aim is to establish a text of what Galois wrote. The details of what he did, the proper evidence of his genius, deserve to be well understood and appreciated by mathematicians as well as historians of mathematics.

Download or read book Dictionary of Abbreviations in Medical Sciences written by Rolf Heister and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Not everyone is a friend of the manifold abbreviations that have by now beCome a part of the scientific language of medicine. In order to avoid misunderstanding these abbreviations, it is wise to refer to a reliable dic tionary, such as this one prepared by Heister. The abbreviation ED means, for instance, effective dose to the pharmacologist. However, it might also stand for emetic dose. Radiologists use the same abbreviation for erythema dose, and ED could also mean ethyl dichlorarsine. A com mon meaning of ECU is European currency unit, a meaning that might not be very often in scientific medical publications. ECU, however, also means environmental control unit or European Chiropractic Union. Hopefully, those making inventions and discoveries will make use of Heister's dictionary before creating new abbreviations when preparing manuscripts for scientific publications. It is a very worthwhile goal not to use the same abbreviation for several different terms, especially if it is already widely accepted to mean only one of them. It may be impossible, however, to achieve this goal in different scientific disciplines. Therefore, although it is wise for the abbreviations used in a publication to be defined, it is also very helpful for readers and writers to use a dictionary such as this one. The author deserves our warmest thanks since we know that compiling such a comprehensive dictionary is based upon incredibly hard effort.
