It is commonly assumed that if the Sun suddenly turned into a black hole, it would suck Earth and the rest of the planets into oblivion. Yet, as prominent author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in mind, Bennett begins an entertaining introduction to Einstein's theories of relativity, describing the amazing phenomena readers would actually experience if they took a trip to a black hole. The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: E = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe. It is not "just a theory"-every major prediction of relativity has been tested to exquisite precision, and its practical applications include the Global Positioning System (GPS). Amply illustrated and written in clear, accessible prose, Bennett's book proves anyone can grasp the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important to science and the way we view ourselves as human beings.

Pourquoi, si longtemps après sa publication en 1905, aurait-on encore besoin d’un nouveau livre sur la relativité d’Einstein ? Parce que malgré la littérature abondante dans ce domaine, peu d’ouvrages se limitent au formalisme mathématique strictement nécessaire pour faire comprendre aux lecteurs le sens physique de cette théorie. D’après David Mermin, la relativité devrait être une partie importante de l’éducation de chacun car après tout, c’est en grande partie une question de temps, un sujet que tout le monde connaît bien ! Le livre révèle que certaines de nos notions les plus intuitives sur le temps sont fausses et que la nature réelle du temps découverte par Einstein peut être rigoureusement expliquée sans mathématiques avancées. Cet ouvrage est le fruit de plus de trente ans d’expérience d’enseignement auprès d’étudiants non scientifiques. L’approche proposée est imaginative, précise et complète. Clair, vivant et informel, ce livre séduira les lecteurs intellectuellement curieux de toutes sortes, y compris les physiciens professionnels, qui seront intrigués par son approche très originale. N. David Mermin est un physicien théorique, membre de l’Académie nationale des sciences, qui a remporté le premier prix Julius Edgar Lilienfeld de la société américaine de physique pour « sa remarquable clarté et son esprit de conférencier auprès de non-spécialistes sur des sujets difficiles ».

This undergraduate textbook introduces relativity to a non-technical audience. The 'thinking tools' approach allows readers to understand at a much deeper level than popular treatments, and end-of-chapter problems (always lacking in popular books) help build and cement that understanding.

This book brings together recent advances in tensor analysis and studies of its invariants such as twistors, spinors, kinematic tensors and others belonging to tensor algebras with extended structures to Lie algebras, Kac-Moody algebras, and enveloping algebras, among others. Chapters cover such topics as classical tensors and bilinear forms, tensors for exploring space-time, tensor applications in geometry and continuum media, and advanced topics in tensor analysis such as invariant theory, derived categories, hypercohomologies, k-modules, extensions of kinematic tensors, infinite dimensional operators, and more.

Questo libro è stato ideato per un corso che spieghi, nella maniera più semplice possibile, le Teorie della Relatività Ristretta e Generale a studenti che si accostano ad esse per la prima volta. I contenuti di queste due teorie fanno ormai parte del bagaglio culturale necessario ad ogni fisico e ad ogni matematico e, in particolare, esse costituiscono un insieme di conoscenze indispensabili per chiunque si occupi di fisica, astrofisica e cosmologia. This book is designed to explain, in the simplest way possible, the Theories of Special and General Relativity to students who are approaching them for the first time. The contents of these two theories are now part of the cultural background needed by every physicist and mathematician, and, in particular, they constitute an indispensable body of knowledge for anyone involved in physics, astrophysics and cosmology.
