There is little doubt that Einstein's theory of relativity captures the imagination. Not only has it radically altered the way we view the universe, but the theory also has a considerable number of surprises in store. This is especially so in the three main topics of current interest that this book reaches, namely: black holes, gravitational waves, and cosmology. The main aim of this textbook is to provide students with a sound mathematical introduction coupled to an understanding of the physical insights needed to explore the subject. Indeed, the book follows Einstein in that it introduces the theory very much from a physical point of view. After introducing the special theory of relativity, the basic field equations of gravitation are derived and discussed carefully as a prelude to first solving them in simple cases and then exploring the three main areas of application. This new edition contains a substantial extension content that considers new and updated developments in the field. Topics include coverage of the advancement of observational cosmology, the detection of gravitational waves from colliding black holes and neutron stars, and advancements in modern cosmology. Einstein's theory of relativity is undoubtedly one of the greatest achievements of the human mind. Yet, in this book, the author makes it possible for students with a wide range of abilities to deal confidently with the subject. Based on both authors' experience teaching the subject this is achieved by breaking down the main arguments into a series of simple logical steps. Full details are provided in the text and the numerous exercises while additional insight is provided through the numerous diagrams. As a result this book makes an excellent course for any reader coming to the subject for the first time while providing a thorough understanding for any student wanting to go on to study the subject in depth

The revised and updated 2nd edition of this established textbook provides a self-contained introduction to the general theory of relativity, describing not only the physical principles and applications of the theory, but also the mathematics needed, in particular the calculus of differential forms. Updated throughout, the book contains more detailed explanations and extended discussions of several conceptual points, and strengthened mathematical deductions where required. It includes examples of work conducted in the ten years since the first edition of the book was published, for example the pedagogically helpful concept of a "river of space" and a more detailed discussion of how far the principle of relativity is contained in the general theory of relativity. Also presented is a discussion of the concept of the 'gravitational field' in Einstein's theory, and some new material concerning the 'twin paradox' in the theory of relativity. Finally, the book contains a new section about gravitational waves, exploring the dramatic progress in this field following the LIGO observations. Based on a long-established masters course, the book serves advanced undergraduate and graduate level students, and also provides a useful reference for researchers.

Introducing Special Relativity provides an easy and rewarding way into special relativity for first and second year university students studying physics. The author establishes the fundamentals of relativity at the outset of this book so readers fully understand the principles and know how to them before moving on to subjects, like time dilation, that often are a source of difficulty for students. The primary topics addressed include conserved relativistic energy and momentum, applications of the Lorentz transformation, and developments in 20th-century physics. This volume also reviews some of the early experiments in the development of special relativity.

Introduction to Relativity is intended to teach physics and astronomy majors at the freshman, sophomore or upper-division levels how to think about special and general relativity in a fundamental, but accessible, way. Designed to render any reader a "master of relativity", everything on the subject is comprehensible and derivable from first principles. The book emphasizes problem solving, contains abundant problem sets, and is conveniently organized to meet the needs of both student and instructor. - Simplicity: the book teaches space and time in relativity in a physical fashion with minimal mathematics - Conciseness: the book teaches relativity by emphasizing the basic simplicity of the principles at work - Visualization: space-time diagrams (Minkowski) illustrate phenomena from simultaneity to the resolution of the twin paradox in a concrete fashion - Worked problems: two chapters of challenging problems solved in several ways illustrate and teach the principles - Problem sets: each chapter is accompanied by a full set of problems for the student that teach the principles and some new phenonmena

Einstein's Theories of Relativity looks at the life and times of the man himself and the beliefs about the laws of physics prior to his theories. It explains what relativity is, & how we can understand it in relation to our everyday lives, before investigating in detail the theories of Special and General Relativity. The book goes on to show how these amazing ideas opened up a whole new understanding of universal forces, from the power in the nucleus of an atom to the way massive bodies in space behave.

General Relativity is a beautiful geometric theory, simple in its mathematical formulation but leading to numerous consequences with striking physical interpretations: gravitational waves, black holes, cosmological models, and so on. This introductory textbook is written for mathematics students interested in physics and physics students interested in exact mathematical formulations (or for anyone with a scientific mind who is curious to know more of the world we live in), recent remarkable experimental and observational results which confirm the theory are clearly described and no specialised physics knowledge is required. The mathematical level of Part A is aimed at undergraduate students and could be the basis for a course on General Relativity. Part B is more advanced, but still does not require sophisticated mathematics. Based on Yvonne Choquet-Bruhat's more advanced text, General Relativity and the Einstein Equations, the aim of this book is to give with precision, but as simply as possible, the foundations and main consequences of General Relativity. The first five chapters from General Relativity and the Einstein Equations have been updated with new sections and chapters on black holes, gravitational waves, singularities, and the Reissner-Nordstrom and interior Schwarzchild solutions. The rigour behind this book will provide readers with the perfect preparation to follow the great mathematical progress in the actual development, as well as the ability to model, the latest astrophysical and cosmological observations. The book presents basic General Relativity and provides a basis for understanding and using the fundamental theory.

Today, Relativity is becoming an integrated aspect of engineering fields. Its application to the Global Positioning System (GPS), extends in usage from smart watches to the navigation of cars, airplanes (drones) and even autonomous tractors. In rather expensive particle accelerators, physicists are everyday 'playing' with Relativistic Billiards, common to the betatrons of cancer therapy using electrons. Computer programs, such as 'ray tracing' methods, are enhanced to simulate objects in relativistic motion, which now offer us relativistic visualizations of accretion disks around compact, astrophysical objects like Black Holes.Against the backdrop of the applications explained throughout the chapters, this book takes on a practical and intuitive approach in introducing the Lorentz invariance of light propagation and space-time concepts. The book begins with simple mathematics, like the classical Pythagoras formula for energy-momentum 'triangles'. Later, readers will find the intuitive vector calculus reemerging in the expansion of full relativistic expressions. Prepared with instructive diagrams of recent experiments, even the layperson can grasp the essential study of Relativity and marvel at its applications within this book.

Einstein's theory of gravity can be difficult to introduce at the undergraduate level, or for self-study. One way to ease its introduction is to construct intermediate theories between the previous successful theory of gravity, Newton's, and our modern theory, Einstein's general relativity. This textbook bridges the gap by merging Newtonian gravity and special relativity (by analogy with electricity and magnetism), a process that both builds intuition about general relativity, and indicates why it has the form that it does. This approach is used to motivate the structure of the full theory, as a nonlinear field equation governing a second rank tensor with geometric interpretation, and to understand its predictions by comparing it with the, often qualitatively correct, predictions of intermediate theories between Newton's and Einstein's. Suitable for a one-semester course at junior or senior level, this student-friendly approach builds on familiar undergraduate physics to illuminate the structure of general relativity.

The present volume grew out of a double session of the Boston Collo quium for the Philosophy of Science held in Boston on March 25, 1983. The papers presented there (by Biezunski, Glick, Goldberg, and Judith Goodstein!) offered both sufficient comparability to establish regulari ties in the reception of relativity and Einstein's impact in France, Spain, the United States and Italy, and sufficient contrast to suggest the salience of national inflections in the process. The interaction among the participants and the added perspectives offered by members of the audience suggested the interest of commissioning articles for a more inclusive volume which would cover as many national cases as we could muster. Only general guidelines were given to the authors: to treat the special or general theories, or both, hopefully in a multidisciplinary setting, to examine the popular reception of relativity, or Einstein's personal impact, or to survey all these topics. In a previous volume, on the 2 comparative reception of Darwinism, one of us devised a detailed set of guidelines which in general were not followed. In our opinion, the studies in this collection offer greater comparability, no doubt because relativity by its nature and its complexity offers a sharper, more easily bounded target. As in the Darwinism volume, this book concludes with an essay intended to draw together in comparative perspective some of many themes addressed by the participants.
