Book excerpt: La physique est-elle à la veille d’une révolution ? Agités par la possibilité de résoudre l’énigme de la masse manquante, la plus grande partie de la matière de l’univers qui n’a jamais pu être observée, les astrophysiciens sont en quête d’une énergie noire et d’une matière noire. Mais sont-ils encore capables d’idées audacieuses ? N’ont-ils pas plutôt des soucis de carrière que la tête dans les étoiles ? Mêlant humour et sérieux, Michel Cassé et Jacques Paul ont cherché à répondre à ces deux questions au fil d’une intrigue amoureuse qui nous plonge dans la physique telle qu’elle se fait au jour le jour dans les laboratoires. Perplexité : qu’est-ce qui relève le plus de la fiction ? La physique de la matière noire ou l’intrigue qu’ils ont imaginée ? Michel Cassé et Jacques Paul sont astrophysiciens au Commissariat à l’énergie atomique. Jacques Paul est l’auteur de L’Homme qui courait après son étoile. Michel Cassé a notamment publié Du vide et de la création, Généalogie de la matière et Énergie noire, matière noire.

Available in PDF, EPUB and Kindle. Book excerpt: Accessible à tous les lecteurs intéressés par les grandes questions relatives à la nature profonde de l'espace, du temps et de la matière, cet ouvrage publié avec le journal Le Monde met en scène les enjeux cruciaux de la cosmologie actuelle. Sa première partie se consacre aux fascinants trous noirs, ces puits de gravité qui font disparaître la matière et la lumière. Depuis les premiers modèles théoriques des années 1960, des progrès décisifs ont été accomplis pour prouver leur réalité physique : en 2015, des astrophysiciens américains ont détecté les ondes gravitationnelles produites par des collisions de trous noirs, puis en 2019, pour la première fois, une image télescopique met à jour un trou noir géant entouré d'un disque de gaz chaud. La seconde partie aborde deux problèmes majeurs non résolus de la science moderne : la matière noire, invisible mais nécessaire pour expliquer les mouvements apparents des astres, et l'énergie sombre, insaisissable mais indispensable pour rendre compte de l'accélération observée de l'expansion de l'espace. Ensemble, la matière et l'énergie noires constituent 95 % du contenu total de l'Univers, la matière ordinaire dont sont composés les planètes, les étoiles, les gaz et poussières cosmiques ne représentant que 5 %. L'ombre est assurément une insatiable circonspection étoilée. Riches de cette intuition poétique, plongeons dans la fascinante dualité entre l'invisible et le visible, entre l'ombre et la lumière.

Available in PDF, EPUB and Kindle. Book excerpt: Mon ouvrage précédent L’impensable immensité de l’infini et le Big bang a pu démontrer que l’apparition de l’Univers il y a près de quatorze milliards d’années, ce que l’on appelle le Big bang, a commencé par une implosion d’une durée infiniment courte d’une partie de l’espace infini noir et monotone, suivie d’une explosion dans le « vide absolu » créé localement par cette implosion de l’espace. C’était déjà une avancée postulée impossible par les scientifiques. Dans ce présent ouvrage, je vais montrer que ce qui s’était d’abord formé est ce que l’on appelle maintenant un trou noir. Comme dirait Stephen Hawking, ce trou noir s’évapore. En réalité le terme s’évapore n’est pas correct. Le trou noir ne s’évapore pas, mais en raison de l’attraction due à la propagation du vide absolu créé par l’implosion, se disperse en trous noirs plus petits qui à leur tour s’éloignent de plus en plus vite les uns des autres dans l’espace. Et les galaxies sont faites d’étoiles enserrant un trou noir... Étoiles faites d’atomes, qui formés de milliards de quanta, sont des trous noirs infiniment plus petits que le trou noir originel.

Download or read book Pr cis of the Lectures on Architecture written by Jean-Nicolas-Louis Durand and published by Getty Publications. This book was released on 2000-01-01 with total page 363 pages. Available in PDF, EPUB and Kindle. Book excerpt: Jean-Nicolas-Louis Durand (1760–1834) regarded the Précis of the Lectures on Architecture (1802–5) and its companion volume, the Graphic Portion (1821), as both a basic course for future civil engineers and a treatise. Focusing the practice of architecture on utilitarian and economic values, he assailed the rationale behind classical architectural training: beauty, proportionality, and symbolism. His formal systematization of plans, elevations, and sections transformed architectural design into a selective modular typology in which symmetry and simple geometrical forms prevailed. His emphasis on pragmatic values, to the exclusion of metaphysical concerns, represented architecture as a closed system that subjected its own formal language to logical processes. Now published in English for the first time, the Précis and the Graphic Portion are classics of architectural education.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.
Download or read book The Violence of Modernity written by Debarati Sanyal and published by JHU Press. This book was released on 2020-03-03 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Violence of Modernity turns to Charles Baudelaire, one of the most canonical figures of literary modernism, in order to reclaim an aesthetic legacy for ethical inquiry and historical critique. Works of modern literature are commonly theorized as symptomatic responses to the trauma of history. In a climate that tends to privilege crisis over critique, Debarati Sanyal argues that it is urgent to rethink literary experience in terms that recall its contestatory potential. Examining Baudelaire's poems afresh, she shifts the focus of critical attention toward an account of modernism as an active engagement with violence, specifically the violence of history in nineteenth-century France. Sanyal analyzes a literary current that uses the traditional hallmarks of modernism—irony, intertextuality, self-reflexivity, and formalism—to challenge the historical violence of modernity. Baudelaire and the committed ironists writing in his wake teach us how to read and resist the violence of history, and thereby to challenge the melancholy tenor of our contemporary "wound culture." In a series of provocative readings, Sanyal presents Baudelaire's poetry as an aesthetic form that contests historical violence through rhetorical strategies of complicity, counterviolence, and critique. The book develops a new account of Baudelaire's significance as a modernist by dislodging him both from his traditional status as a practitioner of "art for art's sake" and from his more recent incarnation as the poet of trauma. Following her extended analysis of Baudelaire's poetry, Sanyal in later chapters considers a number of authors influenced by his strategies—including Rachilde, Virginie Despentes, Albert Camus, and Jean-Paul Sartre—to examine the relevance of their interventions for our current climate of trauma and terror. The result is a study that underscores how Baudelaire's legacy continues to energize literary engagements with the violence of modernity.

Download or read book Expanding the Lexicon written by Sabine Arndt-Lappe and published by Walter de Gruyter GmbH & Co KG. This book was released on 2018-01-22 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: The creation of new lexical units and patterns has been studied in different research frameworks, focusing on either system-internal or system-external aspects, from which no comprehensive view has emerged. The volume aims to fill this gap by studying dynamic processes in the lexicon – understood in a wide sense as not being necessarily limited to the word level – by bringing together approaches directed to morphological productivity as well as approaches analyzing general types of lexical innovation and the role of discourse-related factors. The papers deal with ongoing changes as well as with historical processes of change in different languages and reflect on patterns and specific subtypes of lexical innovation as well as on their external conditions and the speakers’ motivations for innovating. Moreover, the diffusion and conventionalization of innovations will be addressed. In this way, the volume contributes to understanding the complex interplay of structural, cognitive and functional factors in the lexicon as a highly dynamic domain.

Available in PDF, EPUB and Kindle. Book excerpt: CERN, the European Laboratory for particle physics, regularly makes the news. What kind of research happens at this international laboratory and how does it impact people's daily lives? Why is the discovery of the Higgs boson so important? Particle physics describes all matter found on Earth, in stars and all galaxies but it also tries to go beyond what is known to describe dark matter, a form of matter five times more prevalent than the known, regular matter. How do we know this mysterious dark matter exists and is there a chance it will be discovered soon? About sixty countries contributed to the construction of the gigantic Large Hadron Collider (LHC) at CERN and its immense detectors. Dive in to discover how international teams of researchers work together to push scientific knowledge forward. Here is a book written for every person who wishes to learn a little more about particle physics, without requiring prior scientific knowledge. It starts from the basics to build a solid understanding of current research in particle physics. A good dose of curiosity is all one will need to discover a whole world that spans from the infinitesimally small and stretches to the infinitely large, and where imminent discoveries could mark the dawn of a huge revolution in the current conception of the material world.
