Theory Of Sellativity

The present book is intended, as far as possible, to give an exact insight into the theory of Relativity to those readers who, from a general scientific and philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. The author has spared himself no pains in his endeavor to present the main ideas in the simplest and most intelligible form, and on the whole, in the sequence and connection in which they actually originated.

Time's 'Man of the Century', Albert Einstein is the unquestioned founder of modern physics. His theory of relativity is the most important scientific idea of the modern era. In this short book Einstein explains, using the minimum of mathematical terms, the basic ideas and principles of the theory which has shaped the world we live in today. Unsurpassed by any subsequent books on relativity, this remains the most popular and useful exposition of Einstein's immense contribution to human knowledge.

Theories Of Relativity has descriptive copy which is not yet available from the Publisher.

The theory of relativity has been hailed as one of the two most important scientific discoveries in the 20th century. This book presents a comprehensive introduction and analysis of the special theory of relativity and its logical and experimental foundations. It explains in detail the basic principles of the relativity theory, introduces all the important experiments and examines the logic in the reasoning of relativistic results and conclusions. The two fundamental postulates, the principle of relativity and the constancy of the speed of light, are extensively discussed in relation to historical and modern experimental findings. The interpretations of all important experimental results in the history of special relativity and the derivations of key theoretical results in special relativity are scrutinized for their logical consistency, uniqueness to special relativity, and simplicity in explanation compared with competing theories. The ten chapters of this book cover 1) the two postulates, their experimental evidence and logical foundation; 2) the Michelson-Morley experiment and all other important experiments on the speed of light and the medium of light including stellar aberration, the Fizeau experiment, Trouton experiment, Trouton-Noble experiment, Sagnac experiment, Kennedy-Thorndike experiment, Ives-Stilwell experiment, and many modern experiments; 3) the derivation of the Lorentz transformation; 4) the variables in the Lorentz transformation and the principle of relativity; 5) time dilation, its experimental evidence and the twin paradox; 6) length contraction and length paradoxes; 7) motion mass and its derivation, relativistic momentum and experimental evidence; 8) mass-energy relation, its derivation and experimental evidence; 9) time and simultaneity; 10) test theories and experimental verification of special relativity. This book is suitable for both academics and students in science and philosophy and other readers who are interested in physics and its associated philosophical issues; space-time theories; the logical foundation of scientific discoveries; the history of science; the methodology of science, especially researchers and students in physics and the philosophy of science.

The basic concepts of relativity theory are conveyed through worked and unworked examples in this text, which requires only elementary algebra and emphasizes physical principles and concepts. 1985 edition.

Semi-technical account includes a review of classical physics (origin of space and time measurements, Ptolemaic and Copernican astronomy, laws of motion, inertia, more) and of Einstein's theories of relativity.

“One of the best popular accounts of how Einstein and his followers have been trying to explain the universe for decades” (Kirkus Reviews, starred review). Physicists have been exploring, debating, and questioning the general theory of relativity ever since Albert Einstein first presented it in 1915. This has driven their work to unveil the universe’s surprising secrets even further, and many believe more wonders remain hidden within the theory’s tangle of equations, waiting to be exposed. In this sweeping narrative of science and culture, an astrophysicist brings general relativity to life through the story of the brilliant physicists, mathematicians, and astronomers who have taken up its challenge. For these scientists, the theory has been both a treasure trove and an enigma. Einstein’s theory, which explains the relationships among gravity, space, and time, is possibly the most perfect intellectual achievement of modern physics—yet studying it has always been a controversial endeavor. Relativists were the target of persecution in Hitler’s Germany, hounded in Stalin’s Russia, and disdained in 1950s America. Even today, PhD students are warned that specializing in general relativity will make them unemployable. Still, general relativity has flourished, delivering key insights into our understanding of the origin of time and the evolution of all the stars and galaxies in the cosmos. Its adherents have revealed what lies at the farthest reaches of the universe, shed light on the smallest scales of existence, and explained how the fabric of reality emerges. Dark matter, dark energy, black holes, and string theory are all progeny of Einstein’s theory. In the midst of a momentous transformation in modern physics, as scientists look farther and more clearly into space than ever before, The Perfect Theory exposes the greater relevance of general relativity, showing us where it started, where it has led—and where it can still take us.
