"Il pleut autant dans le Sahel qu'en Île-de-France ! Transformer le plus grand désert du monde en zone verte, en retenant cette pluie. Commencer par la bande sahélienne. Créer le plus grand puits de carbone et la plus grande plateforme d'accueil pour ses propres habitants ainsi que pour les peuples déplacés, tel est le pari que nous devons prendre le plus tôt possible. Il n'y a pas de date à partir de laquelle il sera trop tard pour réagir. À l'évidence, le monde est déjà engagé dans une profonde mutation climatique, géopolitique et culturelle. Ce livre entend répondre à une urgence : comment organiser le sauvetage ? Que faire maintenant, avec le plus d'efficacité possible ? Apparemment, certaines évidences n'ont même pas été envisagées! La faisabilité de ce projet repose essentiellement sur la rétention de l'eau de pluie qui, cela paraît paradoxal, tombe en abondance sur la bande sahélienne. Cette ligne de front remontera alors vers le nord, inexorablement. Mais l'évolution climatique nous aidera. C'est le second paradoxe. Toutes les pandémies, les guerres et les décadences qui déferlent sur nous ne doivent pas nous distraire de ce but concret, primordial, réalisable et urgent : reverdir le Sahara."--Page 4 of cover.

This second edition course text introduces the fundamental quantum physics of atoms and molecules. With revised and extended content, this book is the first volume in a series of three aiming to present a broad coverage of atomic, molecular, solid-state and statistical physics. Divided into three parts, the first provides a historical perspective leading to the contemporary view of atomic and molecular physics, outlining the principles of non-relativistic quantum mechanics. The second covers the physical description of atoms and their interaction with radiation, whilst the third deals with molecular physics. The book's pedagogical features include conceptual layout sections that define the goals of each chapter, a simplified but rigorous mathematical apparatus, and a thorough discussion of approximations used to develop the adopted physical models.

This extended and updated second edition course text presents a logical and concise introduction to the basic concepts, applications, and physical meaning of quantum mechanics. An initial review of classical mechanics and electromagnetism provides the reader with the context for quantum mechanics. Starting with atomic level experimental results, the probabilistic nature of quantum mechanics is derived, with the wave function related to the statistical theory of random variables. Applying the requirement of Galilean invariance yields the Schrödinger equation, and the Copenhagen interpretation of the wave function is discussed. After numerous basic applications of wave mechanics, including the hydrogen atom and the harmonic oscillator, the text then presents Dirac notation and Hilbert space theory. New chapters discuss perturbation theory, path integrals, scattering theory, and quantum entanglement.

This reference text covers the description, theory and history of room-sized or smaller ring accelerators and Paul traps for the exploration of advanced concepts and techniques in accelerator physics. The book describes the physics of five distinct small ring accelerators, or related devices, as case studies of scaled experiments to illustrate diverse accelerator and beam physics principles with potential applications to advanced larger machines: 1) small electron storage ring at University of Maryland; 2) larger electron/proton ring at Fermilab; 3) compact ion ring accelerator; 4) model fixed-field alternating gradient machine (a cyclotron/synchrotron-like device) that operated in the UK; and 5) Paul traps as RF (radio-frequency) very compact simulators of accelerators. The appendix summarizes basic scaling laws applicable to ring accelerators. It also includes a brief description of computer resources and examples for modelling accelerators.
