This book offers a comprehensive, university-level introduction to Einstein's Special Theory of Relativity. In addition to the purely theoretical aspect, emphasis is also given to its historical development as well as to the experiments that preceded the theory and those performed in order to test its validity.The main body of the book consists of chapters on Relativistic Kinematics and Dynamics and their applications, Optics and Electromagnetism. These could be covered in a one-semester course. A more advanced course might include the subjects examined in the other chapters of the book and its appendices.As a textbook, it has some unique characteristics: It provides detailed proofs of the theorems, offers abundant figures and discusses numerous examples. It also includes a number of problems for readers to solve, the complete solutions of which are given at the end of the book.It is primarily intended for use by university students of physics, mathematics and engineering. However, as the mathematics needed is of an upper-intermediate level, the book will also appeal to a more general readership.

By the end of the astonishing E=mc2, a dedicated reader will have achieved, if only by osmosis, an understanding of Einstein's theory of relativity and feel quite at ease dining with Nobel Prize winners. It's a lucid, even thrilling study: the very best kind of science journalism. I didn't know I could know so much.' Fay Weldon, Books of the Year, Washington Post In 1905, Albert Einstein produced five historic papers that shattered many cherished scientific beliefs. One of those papers introduced the theory of special relativity and his legendary equation, E=mc2. Generations have grown up knowing that equation changed the shape of our world, but without understanding what it really means and why it is so significant. In this fascinating biography David Bodanis tells the story of one of the greatest scientific discoveries in history. He looks at the elements 'e', 'm' and 'c'; and honours the scientists whose landmark discoveries paved the way for Einstein. He plots the course of the equation through the twentieth century, showing how our lives have been revolutionized by its applications; and looks far ahead to the future. But as with any biography, it is the human stories that really ignite the subject - stories of love, courage and tragedy, of near misses, disappointments and disasters that, brought together by Bodanis in this remarkable book, turn Einstein's seemingly impenetrable theory into a dramatic and accessible human achievement. 'Both informative and highly readable...E=mc2 is a wonderful romp through Einstein's famous formula.. this is everything a popular science book should be' DAILY EXPRESS 'Bodanis himself seems like an intellectual thermonuclear explosion, a kind of Jonathan Miller on speed...This is an outstanding introduction to relativity by a gifted practitioner of popular science' INDEPENDENT 'With skill and plenty of colourful anecdotes Bodanis traces the intellectual ancestry of E=mc2...fast moving and entertaining' THE TIMES 'E=mc2 reveals, amongst other wonders, how many women physicists were involved in the story. Which makes this morally improving, as well as fascinating reading' George Walden, Books of the Year, SUNDAY TELEGRAPH 'The book fizzes in the readers imagination' TIMES EDUCATIONAL SUPPLEMENT

Im Alter von 21 Jahren hat W. Pauli einen Handbuchartikel zur Relativitatstheorie verfasst, der bis heute gelesen und zitiert wird. Er ist wohl der beruhmteste Text zum Thema und wurde nicht zuletzt von A. Einstein begeistert gewurdigt. Die vorliegende Neuausgabe enthalt den Originalartikel sowie weitere, teilweise recht ausfuhrliche Erganzungen, die Pauli im Jahre 1956 fur die englische Ausgabe schrieb. Eine Reihe von Anmerkungen des Herausgebers dienen daruber hinaus als Lesehilfen und zeigen Verbindungen zu modernen Entwicklungen auf."

Exact solutions to Einstein 's equations have been useful for the understanding of general relativity in many respects. They have led to such physical concepts as black holes and event horizons, and helped to visualize interesting features of the theory. This volume studies the solutions to the Ernst equation associated to Riemann surfaces in detail. In addition, the book discusses the physical and mathematical aspects of this class analytically as well as numerically.

"Dies ist kein Lehrbuch der theoretischen Physik, auch kein Kompendium der Physikgeschichte ..., vielmehr eine recht anspruchsvolle Sammlung historischer Miniaturen zur Vergangenheit der theoretischen Physik - ihrer "Sternstunden," wenn man so will. Frei vom Zwang, etwas Erschopfendes vorlegen zu mussen, gelingt dem Autor etwas Seltenes: einen "lebendigen" Zugang zum Ideengebaude der modernen Physik freizulegen, ... zu zeigen, wie Physik in praxi entsteht... Als Vehikel seiner Absichten dienen dem Autor geschichtliche Fallstudien, insgesamt sieben an der Zahl. Aus ihnen extrahiert er das seiner Meinung nach Lehrhafte, dabei bestrebt, mathematische Anachronismen womoglich zu vermeiden... Als Student hatte ich mir diese gescheiten Essays zum Werden unserer heutigen physikalischen Weltsicht gewunscht. Sie sind originell, didaktisch klug und genieren sich auch nicht, von der Faszination zu sprechen, die ... von der Physik ausgeht. Unnotig darauf hinzuweisen, das sie ein grundliches "konventionelles" Studium weder ersetzen wollen noch konnen, sie vermogen aber, dazu zu ermuntern." #"Astronomische Nachrichten (zur englischen " "Ausgabe)"#1"

The Physical World offers a grand vision of the essential unity of physics that will enable the reader to see the world through the eyes of a physicist and understand their thinking. The text follows Einstein's dictum that 'explanations should be made as simple as possible, but no simpler', to give an honest account of how modern physicists understand their subject, including the shortcomings of current theory. The result is an up-to-date and engaging portrait of physics that contains concise derivations of the important results in a style where every step in a derivation is clearly explained, so that anyone with the appropriate mathematical skills will find the text easy to digest. It is over half a century since The Feynman Lectures in Physics were published. A new authoritative account of fundamental physics covering all branches of the subject is now well overdue. The Physical World has been written to satisfy this need. The book concentrates on the conceptual principles of each branch of physics and shows how they fit together to form a coherent whole. Emphasis is placed on the use of variational principles in physics, and in particular the principle of least action, an approach that lies at the heart of modern theoretical physics, but has been neglected in most introductory accounts of the subject.

This book has its roots in a series of collaborations in the last decade at the interface between statistical physics and cosmology. The speci?c problem which initiated this research was the study of the clustering properties of galaxies as revealed by large redshift surveys, a context in which concepts of modern statistical physics (e. g. scale-invariance, fractality. . ) ?nd ready application. In recent years we have considerably broadened the range of problems in cosmology which we have addressed, treating in particular more theoretical issues about the statistical properties of standard cosmological models. What is common to all this research, however, is that it is informed by a perspective and methodology which is that of statistical physics. We can say that, beyond its speci?c scienti?c content, this book has an underlying thesis: such interdisciplinary research is an exciting playground for statistical physics, and one which can bring new and useful insights into cosmology. The book does not represent a ?nal point, but in our view, a marker in the development of this kind of research, which we believe can go very much further in the future. Indeed as we complete this book, new developments - which unfortunately we have not been able to include here - have been made on some of the themes described here. Our focus in this book is on the problem of structure in cosmology.

This text explores how Clifford algebras and spinors have been sparking a collaboration and bridging a gap between Physics and Mathematics. This collaboration has been the consequence of a growing awareness of the importance of algebraic and geometric properties in many physical phenomena, and of the discovery of common ground through various touch points: relating Clifford algebras and the arising geometry to so-called spinors, and to their three definitions (both from the mathematical and physical viewpoint). The main point of contact are the representations of Clifford algebras and the periodicity theorems. Clifford algebras also constitute a highly intuitive formalism, having an intimate relationship to quantum field theory. The text strives to seamlessly combine these various viewpoints and is devoted to a wider audience of both physicists and mathematicians. Among the existing approaches to Clifford algebras and spinors this book is unique in that it provides a didactical presentation of the topic and is accessible to both students and researchers. It emphasizes the formal character and the deep algebraic and geometric completeness, and merges them with the physical applications. The style is clear and precise, but not pedantic. The sole pre-requisites is a course in Linear Algebra which most students of Physics, Mathematics or Engineering will have covered as part of their undergraduate studies.

This book concentrates on presenting the theory of special relativity as the geometry of space-time. The presentation is straightforward, complete and reader-friendly, with explanatory asides, that give historical context and links with other branches of physics and mathematics. The first four chapters give a complete description of the special theory and the nature of space and time, with the minimum use of mathematics. The mathematics necessary is introduced in the following five chapters, with the final fifteen chapters devoted to a comprehensive and detailed exposition of Einstein's special relativity. Features: Concentrates on presenting the theory of special relativity as the geometry of space-time The presentation is straightforward, complete and reader-friendly, with explanatory asides, which give historical context and links with other branches of physics and mathematics

A Physics Today Best Book of the Year A Forbes "For the Physics and Astronomy Lover in Your Life" Selection "Succinct, accessible, and remarkably timely... This book is a rare find." -Physics Today "Belongs on the shelf of anyone interested in learning the scientific, historical, and personal stories behind some of the most incredible scientific advances of the 21st century." -Forbes The detection of gravitational waves has already been called the scientific breakthrough of the century. Einstein predicted these tiny ripples in the fabric of spacetime over a hundred years ago, but they were only recently perceived directly for the first time. Ripples in Spacetime is an engaging account of the international effort to complete Einstein's project, capture his elusive ripples, and launch an era of gravitational-wave astronomy that promises to explain, more vividly than ever before, our universe's structure and origin. "Schilling's deliciously nerdy grand tour takes us through compelling backstory, current research, and future expectations." -Nature "A lively and readable account... Schilling underlines that this discovery is the opening of a new window on the universe, the beginning of a new branch of science." -Graham Farmelo, The Guardian

In 1921, five years after the appearance of his comprehensive paper on general relativity and twelve years before he left Europe permanently to join the Institute for Advanced Study, Albert Einstein visited Princeton University, where he delivered the Stafford Little Lectures for that year. These four lectures constituted an overview of his then-controversial theory of relativity. Princeton University Press made the lectures available under the title "The Meaning of Relativity," the first book by Einstein to be produced by an American publisher. As subsequent editions were brought out by the Press, Einstein included new material amplifying the theory. A revised version of the appendix "Relativistic Theory of the Non-Symmetric Field," added to the posthumous edition of 1956, was Einstein's last scientific paper.

... schon wieder ein neues Buch iiber die Spezielle Relativitatstheorie. Wozu? Es gibt doch wirklich genug gute Biicher zu diesem Thema. Das ist eigentlich auch unsere Ansicht; warum wir dann doch dieses Manuskript fertiggestellt haben, ist eine Verkettung eher ungewollter Umstande. 2uerst entstand, als Folge eines leichtsinnigen Versprechens, das ich H6rern meiner Vorlesung - nicht ahnend, wieviel Zeit die Ausarbeitung erfordern wiirde - gegeben hatte, eine Reinschrift der Vorlesungsvor- bereitung. Dieses Skript fand, wie man heute sagt., eine erstaunliche Akzeptanz, vermutlich, weil die modernen yom Fernsehen verw6hn- ten Studenten in Vorlesungen nicht mehr gerne mitschreiben, sondern Vorlesungen mehr als Unterhaltungsveranstaltungen ansehen wollen. Nachdem damit fUr uns dieser Punkt abgehakt war und die Leh- re wieder etwas hinter die Forschung zuriicktreten sollte, kam Herr Schwarz yom Verlag Vieweg und wollte das Skript als Lehrbuch her- ausbringen, was grundsatzlich natiirlich kein Problem gewesen ware, heutzutage ist ja alles cameraready im Computer. Aber Herr Schwarz, als moderner Physiker, meinte, ein heutiges Buch iiber spezielle Relati- vitatstheorie miiBte 'rf, ..v enthalten und nicht das zwar praktische, aber altmodische i von Minkowski. Da er damit im Prinzip recht hatte, ging die Formuliererei ab Kapitel 5 von neuem los.

Nonspecialists with no prior knowledge of physics and only reasonable proficiency with algebra can now understand Einstein's special theory of relativity. Effectively diagrammed and with an emphasis on logical structure, Leo Sartori's rigorous but simple presentation will guide interested readers through concepts of relative time and relative space.
Sartori covers general relativity and cosmology, but focuses on Einstein's theory. He tracks its history and implications. He explores illuminating paradoxes, including the famous twin paradox, the "pole-in-the-barn" paradox, and the Loedel diagram, which is an accessible, graphic approach to relativity. Students of the history and philosophy of science will welcome this concise introduction to the central concept of modern physics.

Das Lehrbuch soll Studierende mit Interesse an den theoretischen Naturwissenschaften, deren Kenntnisse im wesentlichen aus einem Grundkurs der Differential- und Integralrechnung wie etwa fur Ingenieurfacher bestehen, in die klassische Feldtheorie mit modernen mathematischen Methoden einfuhren. Dementsprechend sind die Tensoranalysis und die Differentialgeometrie die mathematischen Themen, die Geometrie der Raum-Zeit und das Prinzip der Relativitat im Zusammenhang mit den Grundgesetzen der Elektrodynamik und der Gravitation die physikalischen. Mit Rucksicht auf die Mathematik der Relativitatstheorie, aber auch aus didaktischen Erwagungen, gliedert sich der Text in zwei Teile. Um den Leser unter einfacheren Anforderungen an das Vorstellungsvermogen mit der Methodik vertraut zu machen, wird zunachst der affine und euklidische Raum den mathematischen Objekten zugrundegelegt, um verallgemeinernd zur komplexeren Geometrie auf Mannigfaltigkeiten und Riemannschen Raumen hinuberfuhren zu konnen. Die Tensoranalysis in ebenen und gekrummten Raumen wird durch eine Einfuhrung in die spezielle und allgemeine Relativitatstheorie erganzt und abgeschlossen, wobei die Geometrie der Raum-Zeit und die Formulierung der Grundgesetze sowie mathematische Folgerungen zur Sprache kommen.

"Oh, what a delightful book This is the clearest explanation of relativity available--and the most fun. It's great to have it available again. Whether or not you're a scientist, you will relish this book."--Walter Isaacson, author of "Einstein: His Life and Universe" "A clear and vivid exposition of the essential ideas and methods of the theory of relativity . . . can be warmly recommended especially to those who cannot spend too much time on the subject."--Albert Einstein "If you know high-school math, are not afraid of equations, and want to find out what Einstein really said, read Lillian Lieber's book. She will lead you through special and general relativity, helping you at every step to understand the essential equations, including tensors, with amazing clarity and conciseness. This uniquely charming book remains as vivid as ever and even more helpful, thanks to the excellent new foreward and notes by David Derbes and Robert Jantzen."--Peter Pesic, author of "Abel's Proof: An Essay on the Sources" "and Meaning of Mathmatical Unsolvability" and "Sky in a Bottle" "Does the nature of time fascinate you? Does gravity seem a mysterious subject? Are you interested in learning just what it is that Einstein actually did that made him so famous? Then this wonderful book is just the thing. I read the original 1945 edition when I was a high-school student in the 1950s, and it had a tremendous impact on me. I predict the same experience for you, or perhaps a young friend, with this new, updated edition."--Paul J. Nahin, author of "Time Machines," "Oliver Heaviside," and "Dr. Euler's Fabulous Formula"

Using "just enough mathematics to help and not to hinder the lay reader," Lillian R. Lieber provides a thorough explanation of Albert Einstein's theory of relativity. Her delightful style, in combination with her husband's charming illustrations, makes for an interesting and accessible read about one of the most celebrated ideas of all times.

Lillian R. Lieber was a professor and head of the Department of Mathematics at Long Island University. She wrote a series of lighthearted (and well-respected) math books, many of them illustrated by her husband, Hugh Gray Lieber.

David Derbes teaches physics at the University of Chicago Laboratory Schools.

Robert Jantzen is a professor of mathematics at Villanova University.

Gitter messen, wenn WH dafUr ausschlieBlich geometrische Gebilde verwenden, wel che in diesem Gitter auch physikalisch existieren? Physikalische Objekte, die dafUr in Frage kommen, sind Versetzungen, welche in jedem Kristall in einer ungeheuer groBen Zahl vorhanden sind. Wir suchen dann einmal nach solchen, physikalisch stabilen Formen dieser Versetzungen, die geeignet sind, uns ein MaB fUr eine Lange zu liefern, sowie Ferner nach physikalisch stabilen, schwingenden Versetzungen, die uns eine Schwingungsdauer fUr eine Uhr hergeben. Dies gelingt mit einer sehr ge nau untersuchten Gleichung fUr Versetzungen in Kristallen, mit der sog. sine Gordon - Gleichung, fUr die wir eine denkbar einfache physikalische BegrUndung angeben konnen. Darauf aufbauend werden wir dann einen relativistischen Effekt nach dem andern entdecken, am Ende auch das Prinzip von der universellen Konstanz einer ausgezeichneten Signalgeschwindigkeit, welche hier auf dem Gitter definiert ist: Die Kontinuumsnaherung eines Kristallgitters wird als Modell einer relativistischen Raum - Zeit erkennbar. Die Grundidee, die zu dieser Reduktion der relativistischen Phanomene auf be grifflich leichter faBbare Aussagen fuhrt, laBt sich kurz so formulieren: FUr die physikalischen Konstituenten eines idealen Raumgitters postulieren wir die Axio matik der Newtonschen Mechanik. Aber erst die auf diesem Gitter existierenden, lokalen Abweichungen von der idealen Struktur (Konfigurationen von Versetzun gen im KristaII) besitzen in bezug auf dieses Gitter diejenigen tragen Massen, deren Bewegung wir beobachten und fUr deren Bewegung wir dann - innerhalb relativ leicht Uberschaubarer GUltigkeitsgrenzen - die Gesetze der SpezieIIen Relativitats theorie finden."

This text is more conceptually and mathematically than experimentally orientated, elaborating on the underlying logic and dwelling on the subtleties and apparent paradoxes. In this updated edition additional examples and problems have been included.

This book is an introduction to gravitational waves and related astrophysics. It provides a bridge across the range of astronomy, physics and cosmology that comes into play when trying to understand the gravitational-wave sky. Starting with Einstein's theory of gravity, chapters develop the key ideas step by step, leading up to the technology that finally caught these faint whispers from the distant universe. The second part of the book makes a direct connection with current research, introducing the relevant language and making the involved concepts less mysterious. The book is intended to work as a platform, low enough that anyone with an elementary understanding of gravitational waves can scramble onto it, but at the same time high enough to connect readers with active research - and the many exciting discoveries that are happening right now. The first part of the book introduces the key ideas, following a general overview chapter and including a brief reminder of Einstein's theory. This part can be taught as a self-contained one semester course. The second part of the book is written to work as a collection of "set pieces" with core material that can be adapted to specific lectures and additional material that provide context and depth. A range of readers may find this book useful, including graduate students, astronomers looking for basic understanding of the gravitational-wave window to the universe, researchers analysing data from gravitational-wave detectors, and nuclear and particle physicists.

Die Sprache und die Methoden der modernen Differentialgeometrie sind in der vergangenen Dekade immer mehr in die theoretische Physik eingedrungen. Was vor 15 Jahren, als das Buch zuerst als Vorlesungsskriptum herauskam, noch extravagant erschien, ist heute ein Gemeinplatz. Dies hat mich in der Ansicht gestarkt, dass die Studenten der theoretischen Physik diese Sprache lernen mussen, je eher desto besser. Schliesslich werden sie die Professoren des 21. Jahrhunderts sein und es ware absurd, wurden sie dann die Mathematik des 19. Jahrhunderts lehren. Daher habe ich in der neuen Auflage auf dieser Symbolik beharrt, einige Fehler korrigiert und ein Kapi- tel uber Eichtheorien hinzugefugt. Da es sich gezeigt hat, dass sie die fundamentalen Wechselwirkungen beschreiben und ihre Struktur zumindest auf dem klassischen Ni- veau hinreichend klar ist, scheinen sie mir zur Minimalausrustung zu gehoeren, uber die jeder Theoretiker verfugen muss. Mit Bedauern musste ich davon Abstand nehmen, die neueren Entwicklungen der Kosmologie und Kaluza-Klein-artige Theorien aufzu- nehmen, aber ich fuhlte mich an mein ursprungliches Versprechen gebunden, den Studenten keine theoretischen Spekulationen aufzuburden, fur die es keine sichere experimentelle Evidenz gibt. Vielen Physikern bin ich fur Hinweise bezuglich dieses Bandes sehr verpflichtet. Insbesondere P. Aichelburg, H. Rumpf und vor allem H. Urbantke haben zahlreiche Korrekturen und Verbesserungen angebracht. I. Dahl-Jensen sei dafur gedankt, dass sie manche nach Gefuhl angefertigte Zeichnungen mit dem Computer ins richtige Lot gebracht hat.

A concise introduction to the greatest questions of modern cosmology. What came before the big bang? How will the universe evolve into the future? Will there be a big crunch? Questions like these have no definitive answers, but there are many contending theories. In A Little Book about the Big Bang, physicist and writer Tony Rothman guides expert and uninitiated readers alike through the most compelling mysteries surrounding the nature and origin of the universe. Cosmologists are busy these days, actively researching dark energy, dark matter, and quantum gravity, all at the foundation of our understanding of space, time, and the laws governing the universe. Enlisting thoughtful analogies and a step-by-step approach, Rothman breaks down what is known and what isn't and details the pioneering experimental techniques scientists are bringing to bear on riddles of nature at once utterly basic and stunningly complex. In Rothman's telling, modern cosmology proves to be an intricate web of theoretical predictions confirmed by exquisitely precise observations, all of which make the theory of the big bang one of the most solid edifices ever constructed in the history of science. At the same time, Rothman is careful to distinguish established physics from speculation, and in doing so highlights current controversies and avenues of future exploration. The idea of the big bang is now almost a century old, yet with each new year comes a fresh enigma. That is scientific progress in a nutshell: every groundbreaking discovery, every creative explanation, provokes new and more fundamental questions. Rothman takes stock of what we have learned and encourages readers to ponder the mysteries to come.

In den letzten Dekaden hat das Gebiet der klassischen dynamischen Systeme eine beachtliche Renaissance erlebt, und manches, was beim erst en Erscheinen dieses Kur- ses als mathematisch zu hochgestochen erschien, ist heute Gemeingut der aktiven Physiker geworden. Das Ziel der Neuauflage ist es, . dieser Entwicklung zu dienen, indem ich versucht habe, das Buch leserfreundlicher zu gestalten und Fehler auszu- merzen. Da schon die erste Auflage ffir eine einsemestrige Vorlesung reichlich beladen war, wurde neues Material nur in dem Mafie aufgenommen, als anderes weggelassen oder vereinfacht werden konnte. Eine Erweiterung muf3te jedoch das Kapitel mit dem Be- weis des KAM-Satzes erfahren, urn dem neuen Trend in der Physik Rechnung zu tragen. Dieser besteht nicht nur in der Verwendung feinerer mathematischer Hilfs- mittel, sondern auch in einer Neubewertung des Wortes "fundamental". Was frfiher als Schmutzeffekt abgetan wurde, erscheint heute als Folge eines tieferen Prinzips. Ja so- gar diese Keplerschen Gesetze, welche die Radien der Planetenbahnen bestimmen und die man als mystischen Unsinn gerne verschwieg, scheinen in Richtung einer Wahrheit zu deuten, die sich oberflachlicher Betrachtung verschlief3t: SchachteluI). g vollkomme- ner platonischer Korper ffihrt zu Verhaltnissen von Radien, die irrational sind, aber algebraischen Gleichungen niederer Ordnung genfigen. Gerade solche Irrationalzahlen lassen sich am schlechtesten durch rationale approximieren, und Bahnen mit diesem Radiusverhaltnis sind gegenfiber gegenseitigen Storungen am robustesten, da sie am wenigsten unter Resonanzeffekten leiden. In letzter Zeit wurden einige fiberraschende Resultate fiber chaotische Systeme gefunden, doch hat ten deren Beweise leider den Rahmen dieses Buches gesprengt und muf3ten unterbleiben.
