Böcker av Albert Einstein

The Meaning of Relativity; Four lectures delivered at Princeton University, May, 1921, has been acknowledged as a major work throughout human history, and we have taken precautions to assure its preservation by republishing this book in a modern manner for both present and future generations. This book has been completely retyped, revised, and reformatted. The text is readable and clear because these books are not created from scanned copies.

¿ A popular edition, in a digestible, edited format.¿ New series featuring the greatest works of science and philosophy.¿ New introduction highlights the influence of Einstein and the contemporary response to his work.

A marvelously annotated and illustrated edition of Einstein's South America travel diary In the spring of 1925, Albert Einstein embarked on an extensive lecture tour of Argentina before continuing on to Uruguay and Brazil. In his travel diary, the preeminent scientist and humanitarian icon recorded his immediate impressions and broader reflections on the people he encountered and the locations he visited. Some of the most confounding passages reveal his uncensored views on his host nations. This edition makes available the complete journal Einstein kept on his three-month journey. In these remarkable pages, Einstein enthuses about the stunning vistas of lush vegetation in Rio de Janeiro. His flight in the skies over Buenos Aires thrills him, and he enjoys the cozy atmosphere of Montevideo. He expresses genuine admiration for the Uruguayans, harsh condescension toward the Argentinians, and ambivalent affection for the Brazilians. The illustrious visitor seeks calm refuge on the long ocean voyages, far from the madding crowds of Europe, but the grueling lecture schedule and the adoration of the local masses exhaust him. This edition features stunning facsimiles of the diary's pages accompanied by an English translation, an extensive historical introduction, numerous illustrations, and editorial annotations. Supplementary materials include letters, postcards, statements, and speeches as well as a chronology, a bibliography, and an index.

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 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. 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 someone a few happy hours of suggestive thought!

The theory which is sketched in the following pages forms the most wide-going generalization conceivable of what is at present known as "the theory of Relativity;" this latter theory I differentiate from the former "Special Relativity theory," and suppose it to be known. The generalization of the Relativity theory has been made much easier through the form given to the special Relativity theory by Minkowski, which mathematician was the first to recognize clearly the formal equivalence of the space like and time-like co-ordinates, and who made use of it in the building up of the theory. The mathematical apparatus useful for the general relativity theory, lay already complete in the "Absolute Differential Calculus", which were based on the researches of GAUSS, RIEMANN and CHRISTOFFEL on the non-Euclidean manifold, and which have been shaped into a system by RICCI and LEVI-CIVITA, and already applied to the problems of theoretical physics. I have in part B of this communication developed in the simplest and clearest manner, all the supposed mathematical auxiliaries, not known to Physicists, which will be useful for our purpose, so that, a study of the mathematical literature is not necessary for an understanding of this paper. Finally in this place I thank my friend GROSSMANN, by whose help I was not only spared the study of the mathematical literature pertinent to this subject, but who also aided me in the researches on the field equations of gravitation.

Relativity: The Special and the General Theory began as a short paper and was eventually published as a book written by Albert Einstein with the aim of giving: "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. (From Preface) It was first published in German in 1916 and later translated into English in 1920.[1][2][3] It is divided into 3 parts, the first dealing with special relativity, the second dealing with general relativity and the third dealing with considerations on the universe as a whole. There have been many versions published since the original in 1916 and this proves to be the best translated English edition.

A translation of selected non-English texts included in Volume 16 is available in paperback. Since this supplementary paperback includes only select portions of Volume 16, it is not recommended for purchase without the main volume. Every document in The Collected Papers of Albert Einstein appears in the language in which it was written, and this supplementary paperback volume presents the English translations of select portions of non-English materials in Volume 16. This translation does not include notes or annotations of the documentary volume and is not intended for use without the original language documentary edition, which provides the extensive editorial commentary necessary for a full historical and scientific understanding of the documents.

Relativity: The Special And General Theory, A Popular Exposition, Authorised Translation By Robert W. Lawson (Revised Edition)This book is a result of an effort made by us towards making a contribution to the preservation and repair of original classic literature.In an attempt to preserve, improve and recreate the original content, we have worked towards:1. Type-setting & Reformatting: The complete work has been re-designed via professional layout, formatting and type-setting tools to re-create the same edition with rich typography, graphics, high quality images, and table elements, giving our readers the feel of holding a 'fresh and newly' reprinted and/or revised edition, as opposed to other scanned & printed (Optical Character Recognition - OCR) reproductions.2. Correction of imperfections: As the work was re-created from the scratch, therefore, it was vetted to rectify certain conventional norms with regard to typographical mistakes, hyphenations, punctuations, blurred images, missing content/pages, and/or other related subject matters, upon our consideration. Every attempt was made to rectify the imperfections related to omitted constructs in the original edition via other references. However, a few of such imperfections which could not be rectified due to intentional\unintentional omission of content in the original edition, were inherited and preserved from the original work to maintain the authenticity and construct, relevant to the work.We believe that this work holds historical, cultural and/or intellectual importance in the literary works community, therefore despite the oddities, we accounted the work for print as a part of our continuing effort towards preservation of literary work and our contribution towards the development of the society as a whole, driven by our beliefs. We are grateful to our readers for putting their faith in us and accepting our imperfections with regard to preservation of the historical content. HAPPY READING!
