Le philosophe Nicolas de Cues a écrit le De ludo globi vers la fin de l'année 1463, à Rome. La métaphore plaisante du jeu de la boule lui permet d'illustrer et de clarifier sa pensée. L'exemple du jeu s'inscrit dans le cadre de la recherche de Dieu. Celle-ci, illustrée à son tour par la métaphore de la chasse dans le De venatione sapientiae, exprime la tension entre l'homme et l'absolu, entre la créature qui est image et le Créateur dont elle est l'image. L'homo viator est homo ludens. La vie est un jeu, comme la recherche de Dieu est une course.Maurice de Gandillac avait traduit des passages de cette oeuvre essentielle et surprenante. Hervé Pasqua en offre une traduction intégrale, précédée d'une introduction éclairante.Hervé Pasqua, professeur de philosophie médiévale, titulaire de la chaire Jean-François Mattéi du Centre universitaire méditerranéen (CUM), est chercheur à l'université de Nice. Traducteur des oeuvres de Nicolas de Cues, il est l'auteur, entre autres, de Maître Eckhart ou le procès de l'Un.

MCSE est l'outil de base d'une méthode qui comprend un environnement numérique en développement permanent. C'est un "pap-ebook", c'est-à-dire qu'au livre est associé un site web en accès libre qui permet d'effectuer des exercices directement corrélés au livre (des exercices, un programme pour faire une évaluation réaliste de son niveau, des versions audio pour s'entrainer, un répétiteur lexical pour une révision du vocabulaire scientifique, etc.). D'autres outils sont également proposés pour mieux comprendre et mieux s'exprimer oralement. MCSE est la porte d'entrée de tout cet environnement.
Ici, c'est un homme qui est habité par une jeune fille, venue de la misère du Nord-Est brésilien, à Rio, où elle mourra. « Je jure que ce livre est écrit sans mots. C'est une photographie muette. Ce livre est un silence. Ce livre est une question », écrit-il. Et il est tout occupé d'elle : écrire sa vie, sa mort doit le délivrer, lui qui a échappé au sort sans futur qu'elle subit. Il l'aime, comme on aime ce qu'on a craint de devenir...
S'il avoue être le personnage le plus important des sept que comporte son histoire, il ne dit rien de celui dont la présence s'impose progressivement dans ces pages ; la mort qui efface le feu scintillant et fugace de "L'Heure de l'étoile", l'heure à laquelle celle qui meurt devient, pour un instant, l'étoile de sa propre vie, désormais réalisée.
Luis Garcia Manzano fut de l'un de ces républicains espagnols contraints et forcés de fuir leur pays, d'errer sur les plages du littoral languedocien ou dans les camps des Pyrénées. Déporté à 16 ans à peine, il vécut quarante-deux mois à Mauthausen. Il nous raconte l'extraordinaire pied de nez, à l'horreur, aux brimades, à la faim : comment, avec un groupe d'amis, dans la froide morsure d'un camp de la mort, ils ont eu l'idée folle de créer en 1943 un orchestre typique espagnol, « la Rondalla ».
Ce récit simple et direct écrit en 1972, est un émouvant témoignage de courage et de résistance de l'enfer concentrationnaire, « là-bas ou le destin de notre siècle saigne », comme l'a écrit Aragon.
Edition bilingue française et espagnole.
Group action analysis developed and applied mainly by Louis Michel to the study of N-dimensional periodic lattices is the central subject of the book. Different basic mathematical tools currently used for the description of lattice geometry are introduced and illustrated through applications to crystal structures in two- and three-dimensional space, to abstract multi-dimensional lattices and to lattices associated with integrable dynamical systems. Starting from general Delone sets the authors turn to different symmetry and topological classifications including explicit construction of orbifolds for two- and three-dimensional point and space groups. Voronoï and Delone cells together with positive quadratic forms and lattice description by root systems are introduced to demonstrate alternative approaches to lattice geometry study. Zonotopes and zonohedral families of 2-, 3-, 4-, 5-dimensional lattices are explicitly visualized using graph theory approach. Along with crystallographic applications, qualitative features of lattices of quantum states appearing for quantum problems associated with classical Hamiltonian integrable dynamical systems are shortly discussed. The presentation of the material is presented through a number of concrete examples with an extensive use of graphical visualization. The book is aimed at graduated and post-graduate students and young researchers in theoretical physics, dynamical systems, applied mathematics, solid state physics, crystallography, molecular physics, theoretical chemistry, ...
Once associated with the Cold War and with the Reagan administration's "Star Wars" project, missile defence has now taken on a fresh lease of life. In response to an actual or perceived threat by States and public opinion, it has actually become one of the key topics in redefining the great strategic balances. To a large extent, however, its major technological, financial and military implications are still a mystery. It is true that this is still a difficult subject for a non-specialist public, very often coming down to grotesque misconceptions mixing ballistic missiles and the nuclear threat, pointing the finger at Iran, Syria and North Korea, not forgetting China, Russia, Israel and India, and the role of the United States, etc.
Here the authors offer an educational work intended for the wider public, to reveal the technical, operational and strategic complexity of missile defence.
Multivariate analysis is a popular area in statistics and data

analysis models and methods in practice.
The diverse forms that stars assume in the course of their lives can all be derived from the initial conditions : the mass and the original chemical composition. In this textbook Stars and Stellar Evolution the basic concepts of stellar structure and the main roads of stellar evolution are described. First, the observable parameters are presented, which are based on the radiation emerging from a stellar atmosphere. Then the basic physics is described, such as the physics of gases, radiation transport, and nuclear processes, followed by essential aspects of modelling the structure of stars. After a chapter on star formation, the various steps in the evolution of stars are presented.
This leads us to brown dwarfs, to the way a star changes into the red-giant state and numerous other stages of evolution and ultimately to the stellar ashes such as white dwarfs, supernovae and neutron stars. Stellar winds, stellar rotation and convection all influence the way a star evolves. The evolution of binary stars is included by using several canonical examples in which interactive processes lead to X-ray binaries and supernovae of type Ia. Finally, the consequences of the study of stellar evolution are tied to observed mass and luminosity functions and to the overall evolution of matter in the universe.
The authors aim at reaching an understanding of stars and their evolution by both graduate students and astronomers who are not themselves investigating stars. To that end, numerous graphs and sketches, among which the Hertzsprung-Russell diagram is the dominant one, help trace the ways of stellar evolution. Ample references to specialised review articles as well as to relevant research papers are included.
In the first part of this book, the author synthesizes the main results and formulas of physics-Albert Einstein's, with general relativity, gravitational
waves involving elastic deformable space-time, quantum field theory, Heisenberg's principle, and Casimir's force implying that a vacuum is not
nothingness. In the second part, based on these scientific facts, the author re-studies the fundamental equation of general relativity in a weak
gravitational field by unifying it with the theory of elasticity. He considers the Ligo and Virgo interferometers as strain gauges. It follows from this
approach that the gravitational constant G, Einstein's constant ?, can be expressed as a function of the physical, mechanical and elastic characteristics
of space-time. He overlaps these results and in particular Young's modulus of space-time, with publications obtained by renowned scientists. By
imposing to satisfy the set of universal constants G, c, ?, h and by taking into account the vacuum data, he proposes a new quantum expression of G
which is still compatible with existing serious publications. It appears that time becomes the lapse of time necessary to transmit information from
one elastic sheet of space to another. Time also becomes elastic. Thus, space becomes an elastic material, with a particle size of the order of the
Planck scale, a new deformable ether, therefore different from the non-existent luminiferous ether. Finally, in the third part, in appendices, the author
demonstrates the fundamentals of general relativity, cosmology and the theory of elasticity.
The present book is the result of diverse courses on diffusion. It is intended to give as complete an overview as possible of diffusion in solid media, while relating the process of diffusion to both their physical bases and their applications. A series of a real situations is covered in this account, from self-diffusion of radiotracers to the more complex cases of mass flow under chemical or thermal gradients or under electric fields, or diffusion in structures of lower dimensionality (surfaces and interfaces).
In all these analyses, no category of materials was favored; metals, ionic crystals, oxydes, and semiconductors all had their turn. Only polymers were not specifically touched. One chapter is specifically devoted to techniques for studying diffusion, including methods of numerical simulation, and a last and long chapter gives a number of metallurgical phenomena in which diffusion plays a fundamental role.

For more than a half-century, Mats Hillert has contributed greatly to the Science of Materials. He is widely known and respected as an innovator and educator, a scientist with an enormous breadth of interest and depth of insight. The difficult choice of twenty-four papers from a publication list of more than three hundred was carried out in consultation with him. He also suggested or approved names of those scientists who would be invited to write brief introductions to each of the papers.
A brief reading of the topics of the selected papers and their introductions reveals something of their range and depth. Several early selections - including internal reports of the Swedish Institute for Metal Research, published here in their original shape - contained seminal material that established Mats as a leading figure in the study of phase transformations in solids. Others established his presence in the areas of solidification and computational thermodynamics.
This volume represents a judicious sampling only of Mats Hillert's extensive body of work; it is necessarily incomplete, but it is hoped and expected that it will prove useful to students of Material Science and Engineering at all levels, and that it will inspire the further study and appreciation of his many contributions.
This book gives a progress report on the many and original contributions of radiation chemistry to the fundamental knowledge of the vast domain of chemical reactions and its applications. Radiation chemistry techniques indeed make it possible to elucidate detailed physicochemical mechanisms in inorganic and organic chemistry (including in space) and in biochemistry. Moreover, this comprehension is applied in materials science to precisely control syntheses by radiation, such as radiopolymerisation, radiografting, specific treatment of surfaces (textiles, paintings, inks, etc.), synthesis of complex nanomaterials, degradation of environmental pollutants and radioresistance of materials for nuclear reactors.
In life sciences, the study of the effects of radiation on biomacromolecules (DNA, proteins, lipids) not only permits the comprehension of normal or pathological biological mechanisms, but also the improvement of our health. In particular, many advances in cancer radiotherapy, in the radioprotection of nuclear workers and the general population, as well as in the treatment of diseases and the radiosterilization of drugs, could be obtained thanks to this research.
Abundantly illustrated and written in English by top international specialists who have taken care to render the subjects accessible, this work will greatly interest those curious about a scientific field that is new to them and students attracted by the original and multidisciplinary aspects of the field. At a time when radiation chemistry research is experiencing spectacular development in numerous countries, this book will attract many newcomers to the field.
The description of ocean water masses is based on the study of their temperature, salinity, and density, virtual genetic imprints which provide identity and movement to water masses. Ocean characteristics and processes involved in exchanges with the atmosphere together with simple dynamic balances give an understanding of a large part of the vast oceanic system.
This book is enhanced with numerous colored illustrations. It is a reference on regional oceanography updated with extensive results from the last twenty years. The presentation underscores the specificity of each ocean basin using a precise and global approach. Beginning with a brief historical context, it explains the interactions and the role of each ocean basin in the functioning of the planetary ocean. How do we recognize Antarctic Bottom Water in the middle of the Atlantic Ocean? What is the densest water mass? The warmest? Why doesn’t dense water form in the largest ocean basin? What becomes of water that sinks in the Labrador Sea? Why does the ocean play such an important role in climate variations? … Answers can be found in this book.
Beyond a course in regional oceanography, the text is aimed at students in all fields of marine and environmental science as well as interested secondary school teachers. It also provides a guide to exploring the ocean planet that is comprehensible to any well-informed amateur eager to know the basics.

Materials are at the core of our societies and of our economies. They are part of pressing environmental challenges but they also provide powerful answers. It is therefore no longer possible to think of materials from the restricted standpoint of Materials and Engineering Sciences and this book proposes a more holistic vision of their connection with the Environment and with Society.
The book is meant for students, researchers, engineers, and concerned citizens interested in how materials, nature and people interact: at the level of raw materials and energy resources, of innovation and emergence of new materials functions, of historical continuity with materials of the past, and of emissions to air, water and soil and thus in connection also with health and toxicology issues, climate change and collapse of biodiversity. The book examines how materials relate to society with complex metrics, but also, more deeply, how they generate eco-social services, and, finally, have agency along with the people who use them and invent them (Actor Network Theory).
This book is unique in its approach across so many fields. There are many excellent treatises on materials science and more on industrial ecology. However, the connection with the social dimension of sustainability is still rarely discussed and the pluridisciplinary cocktail of approaches used here is truly new.
What is the connection between planet Mars and Iron Man, nickel and the Seven Dwarves, or DNA, walnuts and Jupiter, fuchsine, the fox and Zorro, or even ammoniac and the god Amun?
This book tells the stories behind the naming of the elements, whether they are chemical elements of the Periodic Table, first published by Mendeleev in 1869, or organic elements which are components of DNA and RNA, as well as proteins, themselves elements of living kingdom, plants and animals. The book goes further, into materials and products which became essential elements of modern life.
Readers will learn that the names often refer to (or reveal) dreams and aspirations of men and women of their time. This truly amazing history of the names guides us through an incredible set of worlds: nature, astronomy, history, literature, journeys, and even takes in contributions from legends and mythology.
Big Earth Data in Support of the Sustainable Development Goals 2019 presents 27 case studies of "Big Earth Data Science Engineering Program" (CASEarth) on the development of the Sustainable Development Goals (SDGs) indicators and sustainability assessments in six SDGs, including: SDG 2 (Zero Hunger), SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Cities and Communities), SDG 13 (Climate Action), SDG 14 (Life below Water), and SDG 15 (Life on Land). These cases provide in-depth, systematic research and evaluation results on the selected SDGs and indicators by means of data, method models, and decision support at global, regional, national and local scales. The 27 case studies covered 20 indicators, with focus varying from constructing databases, building index systems, and evaluating indicator progress. Each case study first clearly lists the corresponding SDG targets and indicators it addresses, and then proceeds with the research methods, data, analysis results, and prospects for future research. It can be seen that Big Earth Data as a new scientific methodology has started demonstrating its great value and potential for applications in monitoring and evaluating SDGs for China and developing countries around the world. The report concludes with a summary of the major progress in Big Earth Data for SDGs and future research priorities.
This book describes and comments on the results of research devoted to the studies of phase assemblages in the CaO-SiO2-Al2O3-Fe oxides chemical system, their stability and their evolution in our environment (temperature, pressure). Its aim is to be a research support, not only for researchers and development engineers but also more generally for others interested in materials sciences.
The book is divided in two parts; the first devoted to a description of `the system' using phase diagrams. The second explores the properties and uses of some of the minerals that are in widespread industrial and commercial use.
Much of the work presented in this book is fully original and corresponds to the research undertaken by François Sorrentino from his time at the chemistry department of the University of Aberdeen during the early 1970's, to recent years when he has resumed his interest in mineral research, particularly related to the synthesis of calcium silicates and calcium aluminates, and their industrial manufacture.
The business of upstream oil and gas industry is a complex process that involves multidisciplinary participation. Producing crude oil and natural gas from the subsurface reservoir rocks to the point of the selling terminal requires stage by stage processes that costs several hundreds of millions of dollars to the operating companies. Because of the capital intensive nature of upstream investments, every required process is challenged of its economic impact or benefits it will have on the project's net present value (NPV). The techniques applied in determining the economics of these processes and their selection criteria are addressed in the book.
This book guides the reader through these strategic processes, and presents the participants involved in the business of upstream oil and gas prospecting and the conditions that dictate the field development and investment decisions by investors. It also reveals the shared interests and relationships that exist between international oil companies (IOCs) and national oil companies (NOCs) in the exploration and exploitation of their hydrocarbon resources and reserves. This text will serve the purpose of teaching and learning to those in the energy and financial sectors, as the methods, tools, and techniques discussed throughout the chapters will equip students, tutors, experts, and professionals with the necessary skills and knowledge of Exploration and Production (E&P) projects and energy financing and investment. The principles of project management as it applies in upstream oil/gas projects are discussed as well. And the criteria for project ranking, selection, and budgeting which are sine qua non to project financing and execution are well documented in this book.

Detailed information on the place of publication, including author, publication name, year of publication, volume, issue, and page number, are given in detail. Type specimens and collections information for the taxa and their distribution in China, as well as worldwide, are also provided. The bibliographies were compiled from 182 journals and 138 monographs or books published worldwide. In addition, more than 400 herbaria preserve type specimens of Chinese plants are also listed as an appendix.
This book can be used as a basic material for Chinese vascular plant taxonomy, and as a reference for researchers in biodiversity research, environmental protection, forestry and medicinal botany.
The significance of the existence of the system is to realize its function and maintain its stability, that is, the reliability and stability of the reliability. Reliability is affected by factors, component properties and system structure, and its changes are complex. In order to solve this problem, the authors proposed the space fault tree theory in 2012. This book is the first time that the fundamental part of the theory has been presented internationally. The authors of the book are Pro. Tiejun Cui and Dr. Shasha Li.
