Bøger af Albert Einstein

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 text is divided into three parts which deal respectively with the special theory of relativity, with the general theory of relativity, and with considerations on the universe as a whole. The special theory deals with the physics of elementary particles while the general theory is concerned with the force of gravity and its effect on the other forces of nature. These two theories, while exceptional in their explanations of their particular focus, are inconsistent with each other, and it has long been an aim of the science of physics to help resolve these inconsistencies. Einstein proposed that, rather than discarding these two principles for being conflicting, the rules of time and space should be completely revamped and rethought in order to find a way to make these two principles work in harmony. It is Einstein's work on relativity which would earn him the 1921 Nobel Prize in Physics and establish his legacy as one of the most famous scientists of all time. This edition is translated by Robert W. Lawson and is printed on premium acid-free paper.

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.

Hailed as a scientific genius, harassed by the FBI as a subversive for his socialist views.

The great physicist's own explanation of relativity, written for readers unfamiliar with theoretical physics, outlines the special and general theories and presents the ideas in their simplest, most intelligible form.

Albert Einstein is widely considered as one of the greatest minds that ever lived. He developed the theory of relativity, one of the two pillars of modern physics alongside quantum mechanics, and penned the world's most famous equation, E=mc². He was an immense scientist and thinker, and his work is also renowned for its influence on the philosophy of science. As an authentic genius, he was also full of humor; these 100 quotes have been carefully selected to introduce you to his character and witticism in a convenient and efficient format.

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 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 the PrefaceIt 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, the latest in December, 2011. The work has been labeled[by whom?] unique in that it gives readers an insight into the thought processes of one of the greatest minds of the 20th century.Albert Einstein (14 March 1879 - 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass-energy equivalence formula which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office in Bern (1902-1909). He subsequently realized that the principle of relativity could be extended to gravitational fields, and published a paper on general relativity in 1916 introducing his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light and the quantum theory of radiation, the basis of laser, which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.Einstein moved to Switzerland in 1895 and renounced his German citizenship in 1896. After being stateless for more than five years, he acquired Swiss citizenship in 1901, which he kept for the rest of his life. Except for one year in Prague, he lived in Switzerland between 1895 and 1914.

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, Einsteins perspective is indispensable.
