This volume presents a selection of 434 letters from and to the Dutch physicist and Nobel Prize winner Hendrik Antoon Lorentz (1853-1928), covering the period from 1883 until a few months before his death in February 1928. The sheer size of the available correspondence (approximately 6000 letters from and to Lorentz) preclude a full publication. The letters included in this volume have been selected according to various criteria, the most important of which is scientific importance. A second criterion has been the availability of letters both from and to Lorentz, so that the reader can follow the exchange between Lorentz and his correspondent. Within such correspondences a few unimportant items, dealing with routine administrative or organizational matters, have been omitted. An exception to the scientific criterion is the exchange of letters between Lorentz and Albert Einstein, Max Planck, Woldemar Voigt, and Wilhelm Wien during World War I: these letters have been included because they shed important light on the disruption of the scientific relations during the war and on the political views of these correspondents as well as of Lorentz. similar reasons the letters exchanged with Einstein and Planck on post-war political issues have been included. Biographical sketch Hendrik Antoon Lorentz was born on July 18, 1853 in the Dutch town of Arnhem. He was the son of a relatively well-to-do owner of a nursery.

This book is intended for anyone who is interested in a real physical image and order of the physical world surrounding us.In this book Einstein's destruction of physics is documented. The physical reality of gravity, inertial forces, mass, time, double-slit experiment is debunked. It shows that Quarks and Higgs bosons do not exist and that all elementary particles, all rigid matter and all force fields in the Universe are created from compression of ether. It show that Einstein, after 1916 became a more enthusiastic advocate of the proven existence of the ether than supporters of the ether before 1905.The aim of this book is to return physics from its way of metaphysics in the 20th century on the way of the physical reality in the 21st century. This second edition of this book was augmented by twenty pages compared to its first edition. After this augmentation it appears that the argumentation about the unacceptability of the ill-founded physical theories of the 20th century represents a compact corpus.

Pulsars are rapidly spinning neutron stars, the collapsed cores of once massive stars that ended their lives as supernova explosions. In this book, Geoff McNamara explores the history, subsequent discovery and contemporary research into pulsar astronomy. The story of pulsars is brought right up to date with the announcement in 2006 of a new breed of pulsar, Rotating Radio Transients (RRATs), which emit short bursts of radio signals separated by long pauses. These may outnumber conventional radio pulsars by a ratio of four to one. Geoff McNamara ends by pointing out that, despite the enormous success of pulsar research in the second half of the twentieth century, the real discoveries are yet to be made including, perhaps, the detection of the hypothetical pulsar black hole binary system by the proposed Square Kilometre Array - the largest single radio telescope in the world.

To those of us who are not mathematicians or physicists, Einstein's theory of relativity often seems incomprehensible, exotic, and of little real-world use. None of this is true. Daniel F. Styer's introduction to the topic not only shows us why these beliefs are mistaken but also shines a bright light on the subject so that any curious-minded person with an understanding of algebra and geometry can both grasp and apply the theory.

Styer starts off slowly and proceeds carefully, explaining the concepts undergirding relativity in language comprehensible to nonscientists yet precise and accurate enough to satisfy the most demanding professional. He demonstrates how the theory applies to various real-life situations with easy equations and simple, clear diagrams. Styer's classroom-tested method of conveying the core ideas of relativity--the relationship among and between time, space, and motion and the behavior of light--encourages questions and shows the way to finding the answers. Each of the book's four parts builds on the sections that come before, leading the reader by turn through an overview of foundational ideas such as frames of reference, revelatory examples of time dilation and its attendant principles, an example-based exploration of relativity, and explanations of how and why gravity and spacetime are linked. By demonstrating relativity with practical applications, Styer teaches us to truly understand and appreciate its importance, beauty, and usefulness.

Featuring worked and end-of-chapter problems and illustrated, nontechnical explanations of core concepts, while dotted throughout with questions and answers, puzzles, and paradoxes, "Relativity for the Questioning Mind" is an enjoyable-to-read, complete, concise introduction to one of the most important scientific theories yet discovered. The appendixes provide helpful hints, basic answers to the sample problems, and materials to stimulate further exploration.

Physical Relativity explores the nature of the distinction at the heart of Einstein's 1905 formulation of his special theory of relativity: that between kinematics and dynamics. Einstein himself became increasingly uncomfortable with this distinction, and with the limitations of what he called the "principle theory" approach inspired by the logic of thermodynamics. A handful of physicists and philosophers have over the last century likewise expressed doubts about Einstein's treatment of the relativistic behavior of rigid bodies and clocks in motion in the kinematical part of his great paper, and suggested that the dynamical understanding of length contraction and time dilation intimated by the immediate precursors of Einstein is more fundamental. Harvey Brown both examines and extends these arguments (which support a more "constructive" approach to relativistic effects in Einstein's terminology), after giving a careful analysis of key features of the pre-history of relativity theory. He argues furthermore that the geometrization of the theory by Minkowski in 1908 brought illumination, but not a causal explanation of relativistic effects. Finally, Brown tries to show that the dynamical interpretation of special relativity defended in the book is consistent with the role this theory must play as a limiting case of Einstein's 1915 theory of gravity: the general theory of relativity.
Physical Relativity is an original, critical examination of the way Einstein formulated his theory. It also examines in detail certain specific historical and conceptual issues that have long given rise to debate in both special and general relativity theory, such as the conventionality of simultaneity, the principle of general covariance, and the consistency or otherwise of the special theory with quantum mechanics. Harvey Brown's new interpretation of relativity theory will interest anyone working on these central topics in modern physics.

Special relativity is one of the high points of the undergraduate mathematical physics syllabus. Nick Woodhouse writes for those approaching the subject with a background in mathematics: he aims to build on their familiarity with the foundational material and the way of thinking taught in first-year mathematics courses, but not to assume an unreasonable degree of prior knowledge of traditional areas of physical applied mathematics, particularly electromagnetic theory. His book provides mathematics students with the tools they need to understand the physical basis of special relativity and leaves them with a confident mathematical understanding of Minkowski's picture of space-time. Special Relativity is loosely based on the tried and tested course at Oxford, where extensive tutorials and problem classes support the lecture course. This is reflected in the book in the large number of examples and exercises, ranging from the rather simple through to the more involved and challenging. The author has included material on acceleration and tensors, and has written the book with an emphasis on space-time diagrams. Written with the second year undergraduate in mind, the book will appeal to those studying the 'Special Relativity' option in their Mathematics or Mathematics and Physics course. However, a graduate or lecturer wanting a rapid introduction to special relativity would benefit from the concise and precise nature of the book.

Dieses Buch bietet eine klassische, immer noch aktuelle Einfuhrung in die Probleme und die Entwicklung der Relativitatstheorie anhand von gesammelten Originalarbeiten von Albert Einstein, Hendrik Antoon Lorentz, Hermann Minkowski und Hermann Weyl. Der 100. Geburtstag der Allgemeinen Relativitatstheorie im November 2015 diente als Anlass zur Herausgabe der um neun weitere Artikel erganzten Neuauflage dieses Klassikers. In der vorliegenden Neuauflage wurden jetzt auch Einsteins fruhe Arbeiten uber Gravitationswellen aufgenommen, deren erster direkter Nachweis 2017 den Nobelpreis fur Physik erhalten hat. Das Werk "Das Relativitatsprinzip" wurde erstmals 1913 von dem Mathematiker Otto Blumenthal herausgegeben. Das Buch erlebte mehrere Auflagen und umfasste die wesentlichen Arbeiten zur Relativitatstheorie bis zum Jahr 1923. Die Absicht ist es, den Gedankengang Albert Einsteins von der Speziellen Relativitatstheorie, uber die Allgemeine Relativitatstheorie, bis hin zu Einsteins Versuch einer Einheitlichen Feldtheorie von Elektromagnetismus und Gravitation, darzustellen. Das Buch liefert somit nicht nur dem an der Entwicklung der Relativitatstheorie interessierten Physiker und Mathematiker, sondern auch dem an Physik, Mathematik und deren historische Entwicklung interessierten Laien eine wertvolle Quellensammlung.

Bose-Einstein condensation represents a new state of matter and is one of the cornerstones of quantum physics, resulting in the 2001 Nobel Prize. Providing a useful introduction to one of the most exciting fields of physics today, this text will be of interest to a growing community of physicists, and is easily accessible to non-specialists alike.

Relativity Revealed: A Concrete Approach You Can Understand presents Einstein's special theory of relativity in clear and simple language. This book is intended for high school students who may have an interest in science, or for adults who simply want to know what relativity is all about. The material in the book was twice presented by the author, Prof. Ray C. Jones, in a series of popular public lectures at Southwestern Oklahoma State University. Special relativity concerns the differences in physical quantities, such as time intervals, lengths and masses, that occur when measured by observers who are in constant speed motion relative to each other or to the objects being measured. Although relativity begins with simple statements about the speed of light and the nature of clocks, we soon find that it changes our perceptions of space and time and leads to an understanding of nuclear fission and fusion processes and the radiation of energy from the sun. This book, by an exceptional teacher, is a very good place to begin to learn of these things. In this book, Prof. Jones develops the major ideas of relativity from simple postulates about observations of the speed of light. The basic ideas are presented in simple language, but are then extended into a consistent logical framework with the aid of some minimal high school level mathematics. (The details of mathematical developments are presented in Appendices that will help to sharpen reader's skills.)

This book is a considerable amplification and modernisation of the authors' earlier Essential Relativity. It aims to bring the challenge and excitement of modern relativity and cosmology at rigorous mathematical level within reach of advanced undergraduates and beginning graduates, while containing enough new material to interest the experienced lecturer.

On Albert Einstein's seventy-sixth and final birthday, a friend gave him a simple toy made from a broomstick, a brass ball attached to a length of string, and a weak spring. Einstein was delighted: the toy worked on a principle he had conceived fifty years earlier when he was working on his revolutionary theory of gravitya principle whose implications are still confounding physicists today.

Starting with this winning anecdote, Anthony Zee begins his animated discussion of phenomena ranging from the emergence of galaxies to the curvature of space-time, evidence for the existence of gravity waves, and the shape of the universe in the first nanoseconds of creation and today. Making complex ideas accessible without oversimplifying, Zee leads the reader through the implications of Einstein's theory and its influence on modern physics. His playful and lucid style conveys the excitement of some of the latest developments in physics, and his new Afterword brings things even further up-to-date.

Many people know that Einstein invented the theory of relativity, but only few have more than a superficial idea of its content. This book aims to explain the basic features of relativity in detail, emphasising the geometrical aspects by using a large number of diagrams, and assuming no knowledge of higher level mathematics.
