First published in 1916 by the Nobel Laureate, Einstein's research and theories explain, using minimum of mathematical terms, the basic ideas and principles of the theory which have shaped the world we live in today. Regarded as a seminal work in modern physics, Relativity: The Special and General Theory written by one of the world's most brilliant minds encompasses the universe as a whole, and delves into one of the most celebrated scientific theories - the relationship between space and time and the theory of gravitation.

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 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. In this work Einstein intended, as far as possible, to give an exact insight into the theory of relativity to those readers who, from a general and scientific philosophical point of view, are interested in the theory, but who are not conversant with the mathematical apparatus of theoretical physics. The theory of relativity enriched physics and astronomy during the 20th century.

Special and General Relativity by Albert Einstein contains his core paper, 'Relativity, The Special & The General Theory. A Popular Exposition', which established his reputation as one of the greatest thinkers of our and perhaps any age. Also included are the four lectures he gave to explain his findings in more detail: 'The Meaning of Relativity'. FLAME TREE's Great Works That Shape Our World is a new series of definitive books drawing on ancient, medieval and modern writing. Created to entertain, inform and enrich, the new series brings infinite variety to refresh the mind, presented in beautiful editions for the modern market. Each book features a new, accessible introduction, specially written for these editions, placing the book in context both as part of the new series, and highlighting its special contribution to the advancement of human understanding; they examine the significance of each work, their impact at time of publication, and their influence today.

This book has been considered by academicians and scholars of great significance and value to literature. This forms a part of the knowledge base for future generations. We have represented this book in the same form as it was first published. Hence any marks seen are left intentionally to preserve its true nature.

A handsome annotated edition of Einstein’s celebrated book on relativityAfter completing the final version of his general theory of relativity in November 1915, Albert Einstein wrote Relativity. Intended for a popular audience, the book remains one of the most lucid explanations of the special and general theories ever written. This edition of Einstein’s celebrated book features an authoritative English translation of the text along with commentaries by Hanoch Gutfreund and Jürgen Renn that examine the evolution of Einstein’s thinking and cast his ideas in a modern context. Providing invaluable insight into one of the greatest scientific minds of all time, the book also includes a unique survey of the introductions from past editions, covers from selected early editions, a letter from Walther Rathenau to Einstein discussing the book, and a revealing sample from Einstein’s original handwritten manuscript.

The volume contains new publications of five works by Einstein - his valuable book Relativity: The Special and the General Theory, written for a wider audience - and four articles, which nicely complement the issues discussed in the book. The selected works contain not only Einstein's own explanations of his revolutionary contributions to fundamental physics, but also give the readers, particularly his popular book, the unique chance to be exposed to Einstein's original thinking in action. Einstein's five works included in the volume are:1. Relativity: The Special and the General Theory. A Popular Exposition 2. "What is the Theory of Relativity," written at the request of The London Times and published on November 28, 19193. "Ether and the Theory of Relativity," An Address delivered on May 5th, 1920 in the University of Leyden4. "Geometry and Experience," An expanded form of an Address to the Prussian Academy of Sciences in Berlin on January 27th, 19215. "A Brief Outline of the Development of the Theory of Relativity," Nature volume 106, pages 782-784 (17 February 1921)One notable issue - the concept of relativistic mass - is not discussed in Einstein's five works republished in the volume. Although he wrote in his popular book (included here, p. 36) "the inertial mass of a body is not a constant", Einstein did not discuss the concept of relativistic mass (i.e., the relativistic increase of the mass of a body as its velocity increases), which he silently abandoned after using it in his 1905 paper, where he defined longitudinal mass and transverse mass. As Einstein's unclear view of the relativistic mass might have provided some encouragement for "what has probably been the most vigorous campaign ever waged against the concept of relativistic mass," an Appendix "On Relativistic Mass" is included in this volume to address that unprecedented campaign and to help the readers make their own decision on the concept of relativistic mass.

The most advanced and celebrated mind of the 20th Century, without a doubt, is attributed to Albert Einstein. This interesting book allows us to explore his beliefs, philosophical ideas, and opinions on many subjects. Subjects include politics, religion, education, the meaning of life, Jewish issues, the world economy, peace and pacifism. Einstein believed in the possibility of a peaceful world and in the high mission of science to serve human well-being. As we near the end of a century in which science has come to seem more and more remote from human values, Einstein's perspective is indispensable.

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 work presumes a standard of education corresponding to that of a university matriculation examination, and, despite the shortness of the book, a fair amount of patience and force of will on the part of the reader. The author has spared himself no pains in his endeavour 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. In the interest of clearness, it appeared to me inevitable that I should repeat myself frequently, without paying the slightest attention to the elegance of the presentation. I adhered scrupulously to the precept of that brilliant theoretical physicist L. Boltzmann, according to whom matters of elegance ought to be left to the tailor and to the cobbler. I make no pretence of having withheld from the reader difficulties which are inherent to the subject. On the other hand, I have purposely treated the empirical physical foundations of the theory in a "step-motherly" fashion, so that readers unfamiliar with physics may not feel like the wanderer who was unable to see the forest for the trees. May the book bring some one a few happy hours of suggestive thought

Albert Einstein’s travel diary to the Far East and Middle EastIn the fall of 1922, Albert Einstein, along with his then-wife, Elsa Einstein, embarked on a five-and-a-half-month voyage to the Far East and Middle East, regions that the renowned physicist had never visited before. Einstein's lengthy itinerary consisted of stops in Hong Kong and Singapore, two brief stays in China, a six-week whirlwind lecture tour of Japan, a twelve-day tour of Palestine, and a three-week visit to Spain. This handsome edition makes available the complete journal that Einstein kept on this momentous journey. The telegraphic-style diary entries record Einstein's musings on science, philosophy, art, and politics, as well as his immediate impressions and broader thoughts on such events as his inaugural lecture at the future site of the Hebrew University in Jerusalem, a garden party hosted by the Japanese Empress, an audience with the King of Spain, and meetings with other prominent colleagues and statesmen. Entries also contain passages that reveal Einstein's stereotyping of members of various nations and raise questions about his attitudes on race. This beautiful edition features stunning facsimiles of the diary's pages, accompanied by an English translation, an extensive historical introduction, numerous illustrations, and annotations. Supplementary materials include letters, postcards, speeches, and articles, a map of the voyage, a chronology, a bibliography, and an index. Einstein would go on to keep a journal for all succeeding trips abroad, and this first volume of his travel diaries offers an initial, intimate glimpse into a brilliant mind encountering the great, wide world.

This volume covers one of the most thrilling two-year periods in twentieth-century physics, as matrix mechanics—developed chiefly by W. Heisenberg, M. Born, and P. Jordan—and wave mechanics—developed by E. Schrödinger—supplanted the earlier quantum theory. The almost one hundred writings by Einstein, of which a third have never been published, and the more than thirteen hundred letters show Einstein’s immense productivity and hectic pace of life. Einstein quickly grasps the conceptual peculiarities involved in the new quantum mechanics, such as the difference between Schrödinger’s wave function and a field defined in spacetime, or the emerging statistical interpretation of both matrix and wave mechanics. Inspired by correspondence with G. Y. Rainich, he investigates with Jakob Grommer the problem of motion in general relativity, hoping for a hint at a new avenue to unified field theory. Einstein falls victim to scientific fraud when, in a collaboration with E. Rupp, he becomes convinced that the latter’s experiments, aimed at deciding whether excited atoms emit light instantaneously (in quanta) or in a finite time (in waves), confirm a wave-theoretic explanation. While it was known that the teenage Einstein had been romantically involved with Marie Winteler in 1895, newly discovered documents reveal that his love for Marie was rekindled in 1909–10 while he was still married to Mileva Maric. The 1925 Locarno Treaties renew Einstein’s optimism in European reconciliation. He backs the “International manifesto against compulsory military service” and continues his participation in the League of Nations’ International Committee on Intellectual Cooperation. He remains intensely committed to the shaping of the Hebrew University in Jerusalem, although his enthusiasm for this cause is sorely tested.

The theory of relativity usually encompasses two interrelated theories by Albert Einstein: special relativity and general relativity. Special relativity applies to elementary particles and their interactions, describing all their physical phenomena except gravity. General relativity explains the law of gravitation and its relation to other forces of nature. It applies to the cosmological and astrophysical realm, including astronomy. The theory transformed theoretical physics and astronomy during the 20th century, superseding a 200-year-old theory of mechanics created primarily by Isaac Newton. It introduced concepts including spacetime as a unified entity of space and time, relativity of simultaneity, kinematic and gravitational time dilation, and length contraction. In the field of physics, relativity improved the science of elementary particles and their fundamental interactions, along with ushering in the nuclear age. With relativity, cosmology and astrophysics predicted extraordinary astronomical phenomena such as neutron stars, black holes, and gravitational waves.

A must read for all students of physics. While many have written on relativity, this book remains one of the most lucid explanations of the special and general theories ever written. Einstein has a particular authority. He presents the facts but also exposes the thought processes that led him to them, the physical interpretation of his theory.

Relativity - The Special and General Theory/ Sidelights on Relativity is a compilation of two classic Albert Einstein physics papers. Special relativity is a theory of the structure of spacetime. It was introduced in Einstein's 1905 paper "On the Electrodynamics of Moving Bodies" (for the contributions of many other physicists see History of special relativity). Special relativity is based on two postulates which are contradictory in classical mechanics: The laws of physics are the same for all observers in uniform motion relative to one another (principle of relativity). The speed of light in a vacuum is the same for all observers, regardless of their relative motion or of the motion of the light source. The resultant theory copes with experiment better than classical mechanics. For instance, postulate 2 explains the results of the Michelson-Morley experiment. Moreover, the theory has many surprising and counterintuitive consequences. Some of these are: Relativity of simultaneity: Two events, simultaneous for one observer, may not be simultaneous for another observer if the observers are in relative motion. Time dilation: Moving clocks are measured to tick more slowly than an observer's "stationary" clock. Length contraction: Objects are measured to be shortened in the direction that they are moving with respect to the observer. Maximum speed is finite: No physical object, message or field line can travel faster than the speed of light in a vacuum. The effect of Gravity can only travel through space at the speed of light, not faster or instantaneously. Mass-energy equivalence: E = mc2, energy and mass are equivalent and transmutable. Relativistic mass, idea used by some researchers. The defining feature of special relativity is the replacement of the Galilean transformations of classical mechanics by the Lorentz transformations. General relativity is a theory of gravitation developed by Einstein in the years 1907-1915. The development of general relativity began with the equivalence principle, under which the states of accelerated motion and being at rest in a gravitational field (for example, when standing on the surface of the Earth) are physically identical. The upshot of this is that free fall is inertial motion: an object in free fall is falling because that is how objects move when there is no force being exerted on them, instead of this being due to the force of gravity as is the case in classical mechanics. This is incompatible with classical mechanics and special relativity because in those theories inertially moving objects cannot accelerate with respect to each other, but objects in free fall do so. To resolve this difficulty Einstein first proposed that spacetime is curved. In 1915, he devised the Einstein field equations which relate the curvature of spacetime with the mass, energy, and any momentum within it. Some of the consequences of general relativity are: Clocks run slower in deeper gravitational wells. This is called gravitational time dilation. Orbits precess in a way unexpected in Newton's theory of gravity. (This has been observed in the orbit of Mercury and in binary pulsars). Rays of light bend in the presence of a gravitational field. Rotating masses "drag along" the spacetime around them; a phenomenon termed "frame-dragging". The universe is expanding, and the far parts of it are moving away from us faster than the speed of light. Technically, general relativity is a theory of gravitation whose defining feature is its use of the Einstein field equations. The solutions of the field equations are metric tensors which define the topology of the spacetime and how objects move inertially.
