Book Description
This book showcases the fascinating but problematic relationship between human intelligence and artificial intelligence: AI is often discussed in the media, as if bodiless intelligence could exist, without a consciousness, without an unconscious, without thoughts. Using a wealth of anecdotes, data from academic literature, and original research, this short book examines in what circumstances robots can replace humans, and demonstrates that by operating beyond direct human control, strong artificial intelligence may pose serious problems, paving the way for all manner of extrapolations, for example implanting silicon chips in the brains of a privileged caste, and exposing the significant gap still present between the proponents of "singularity" and certain philosophers. With insights from mathematics, cognitive neuroscience and philosophy, it enables readers to understand and continue this open debate on AI, which presents concrete ethical problems for which meaningful answers are still in their infancy.

Book Description
Le titre de l'ouvrage associe à dessein deux termes contradictoires pour caractériser l'objet étudié : les matériaux, certes déformables, qui relèvent de l'état solide. Ce premier volume traite des seuls comportements linéaires de ces matériaux. Le livre étudie ainsi les matériaux constitutifs des structures du secteur industriel, supposés homogènes et isotropes, lorsque les champs de déplacement sont proportionnels aux chargements appliqués. L'étude débute par une méthode de caractérisation globale fondée sur une décomposition des structures en pièces élémentaires (théorie des mécanismes). Très souvent, industriellement, ces structures peuvent être schématisées géométriquement et mécaniquement par des poutres ou des plaques. Le livre présente donc, de manière assez exhaustive, la modélisation des assemblages de poutres droites soumises à tous les types de sollicitations (effort normal, effort tranchant, torsion et flexion) et à leurs combinaisons, La schématisation des plaques est également exposée. Quelques exercices corrigés illustrent les notions abordées. Dans sa présentation l'ouvrage adopte une approche suffisamment formelle pour ne pas constituer une simple collection de cas particuliers, tout en permettant au lecteur une applicabilité assez directe des méthodes exposées à des cas industriels concrets. Un second volume traite des approches non linéaires.

Le titre de l'ouvrage associe à dessein deux termes contradictoires pour caractériser l'objet étudié : les matériaux, certes déformables, qui relèvent de l'état solide. Ce second volume traite des comportements non linéaires de ces solides déformables. Le livre étudie ainsi les matériaux constitutifs des structures du secteur industriel, supposés homogènes et isotropes, lorsque les champs de déplacement ne sont plus proportionnels aux chargements appliqués. L'étude débute par la formulation de l'équilibre quasi-statique en grandes transformations lorsque l'hypothèse des petites perturbations (HPP) n'est plus acceptable. Les conditions «d'instabilité statique» sont décrites. Après une présentation thermodynamique des comportements élasto-plastiques usuels, les théorèmes extrémaux permettant l'encadrement des charges de ruine quasi-statique des structures en plasticité parfaite sont démontrés. Le livre aborde également les sources de non linéarité inertielle avec un développement sommaire de l'acoustique. Enfin, de manière plus détaillée, une technique de résolution explicite des problèmes de dynamique rapide est exposée. Quelques exercices corrigés illustrent les notions abordées. Dans sa présentation l'ouvrage adopte une approche suffisamment formelle pour ne pas constituer une simple collection de cas particuliers, tout en permettant au lecteur une applicabilité assez directe des méthodes exposées à des cas industriels concrets.

Book Description
How do engineering materials deform when bearing mechanical loads? To answer this crucial question, the book bridges the gap between continuum mechanics and materials science. The different kinds of material deformation are explained in detail. The book also discusses the physical processes occurring during the deformation of all classes of engineering materials and shows how these materials can be strengthened to meet the design requirements. It provides the knowledge needed in selecting the appropriate engineering material for a certain design problem. This book is both a valuable textbook and a useful reference for graduate students and practising engineers.

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.

Book Description
This new edition of the near-legendary textbook by Schlichting and revised by Gersten presents a comprehensive overview of boundary-layer theory and its application to all areas of fluid mechanics, with particular emphasis on the flow past bodies (e.g. aircraft aerodynamics). The new edition features an updated reference list and over 100 additional changes throughout the book, reflecting the latest advances on the subject.
