Albert Einstein

To quote Einstein himself, this slim volume was "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". Despite his formidable intellect, Einstein writes in a clear and engaging style, using familiar examples to illustrate his theories and their surprising conclusions. Anyone with a curiosity about the man, and his often misquoted theories, would do well to settle down with this book in a comfortable chair, and shut the door - you will need to think and imagine hard to keep up with Einstein Delve into the world of the infitinely small, infinitely large, and lightning fast, and at least scrape the surface of these two great concepts which laid the foundations for atomic, nuclear and quantum physics in the following decades, and made space flight and modern astronomy possible.

General relativity or the general theory of relativity is the geometric theory of gravitation published by Albert Einstein in 1915. It is the current description of gravitation in modern physics. General relativity generalises special relativity and Newton's law of universal gravitation, providing a unified description of gravity as a geometric property of space and time, or spacetime. In particular, the curvature of spacetime is directly related to the four-momentum (mass-energy and linear momentum) of whatever matter and radiation are present. The relation is specified by the Einstein field equations, a system of partial differential equations. Einstein's theory has important astrophysical implications. For example, it implies the existence of black holes-regions of space in which space and time are distorted in such a way that nothing, not even light, can escape-as an end-state for massive stars. There is evidence that such stellar black holes as well as more massive varieties of black hole are responsible for the intense radiation emitted by certain types of astronomical objects such as active galactic nuclei or microquasars.

Here is the definitive new edition of the hugely popular collection of Einstein quotations that has sold tens of thousands of copies worldwide and been translated into twenty-five languages. The Ultimate Quotable Einstein features 400 additional quotes, bringing the total to roughly 1,600 in all. This ultimate edition includes new sections--"On and to Children," "On Race and Prejudice," and "Einstein's Verses: A Small Selection"--as well as a chronology of Einstein's life and accomplishments, Freeman Dyson's authoritative foreword, and new commentary by Alice Calaprice. In The Ultimate Quotable Einstein, readers will also find quotes by others about Einstein along with quotes attributed to him. Every quotation in this informative and entertaining collection is fully documented, and Calaprice has carefully selected new photographs and cartoons to introduce each section. * Features 400 additional quotations * Contains roughly 1,600 quotations in all * Includes new sections on children, race and prejudice, and Einstein's poetry * Provides new commentary * Beautifully illustrated * The most comprehensive collection of Einstein quotes ever published

Widely considered the greatest contribution to the philosophy of science, Einstein's theory of relativity has often been viewed as comprehensible only to highly trained scientists. This book, however, contains the great physicist's own explanation of both the special and the general theories, written for readers interested in the theory but not conversant with the mathematical apparatus of theoretical physics. Presenting the ideas in their simplest, most intelligible form, this three-part volume outlines the special theory, the general theory, and in a final part, offers considerations on the universe as whole.

In this latest volume, Einstein's visible public persona is amply documented in his correspondence, honors and prizes, lectures and travels, articles, and the many solicitations asking him to join public initiatives. Einstein joins a Zionist fundraising mission led by Ch. Weizmann, and he visits the United States for the first time. Einstein travels to major cities, including New York, Boston, and Chicago, and he delivers his now famous Princeton Lectures. Scientific issues remain at the core of Einstein's preoccupations. Correspondence with N. Bohr, W. Bothe, P. Ehrenfest, H. Geiger, H. A. Lorentz, L. Meitner, and A. Sommerfeld records Einstein's interest in and contributions to the emerging modern quantum theory. He addresses conceptual problems, such as the fundamental nature of light and its emission mechanism, in a proposed experiment with canal rays. Einstein continues to engage in original research, other expert opinions, and patent applications. Throughout the year, Einstein navigates complex territory in his professional and personal life. He travels with his older son to Bologna, yet turns down repeated invitations to Munich. He mends his friendship with M. Born, but receives stinging criticism from F. Haber for traveling to the United States. He supports the nomination of Masaryk for a Nobel Peace Prize, travels to Amsterdam in order to intervene on behalf of Germany at the Paris reparations conference, and assists Russian physicists in their efforts to rebuild and develop Russian science. Einstein's letters reveal his Social Democratic political positions.

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 all non-English materials. This translation does not include notes or annotation 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.

This index volume provides quick access to the most authoritative compilation of documents and information concerning Einstein's work and correspondence for the first half of his life. It offers readers a Cumulative Index to the first ten volumes of the collected papers, the first complete bibliography of Einstein's scientific and nonscientific writings until 1921, and a succinct biographical time line. This volume is an invaluable research tool for delving into Einstein's written legacy; his interactions with colleagues, institutions, friends, and family; and his scientific, political, educational, and social activities. Volume 11 presents three important and unique bibliographies: the List of Writings, 1891-1921; the Einstein Bibliography, 1901-1921; and a Cumulative Bibliography and Index of Citations for Volumes 1-10. The List of Writings includes all of Einstein's manuscripts that remained unpublished by 1921, while the Einstein Bibliography includes documents that were republished during this period. The Cumulative Bibliography and Index of Citations lists all literature written by authors cited in at least one of the first ten volumes of the series. This volume also contains two complete lists of Einstein's correspondence up through 1920, and a Chronology of Einstein's life for the years 1879-1921. The first list presents the correspondence in chronological order, while the second list presents the correspondence in alphabetical order by correspondent. The indexes and bibliographies implicitly correct inconsistencies and errata across the different volumes. Other corrections are explicitly collected in a List of Errata for the first ten volumes of the series.

„In der vorliegenden Ausarbeitung von vier Vorträgen, die ich an der Universität Princeton im Mai 1921 gehalten habe, wollte ich die Hauptgedanken und mathematischen Methoden der Relativitätstheorie zusammenfassen. Dabei habe ich mich bemüht, alles weniger Wesentliche wegzulassen, das Grundsätzliche aber doch so zu behandeln, dass das Ganze als Einführung für alle diejenigen dienen kann, welche die Elemente der höheren Mathematik beherrschen, aber nicht allzuviel Zeit und Mühe auf den Gegenstand verwenden wollen. Auf Vollständigkeit kann diese kurze Darlegung selbstverständlich keinen Anspruch machen, zumal ich die feineren, mehr mathematisch interessanten Entwicklungen, welche sich auf Variationsrechnung gründen, nicht behandelt habe. Mein Hauptziel war es, das Grundsätzliche in dem ganzen Gedankengang der Theorie klar hervortreten zu lassen.“ Albert Einstein (Vorwort zur 1. Auflage der "Vier Vorlesungen über Relativitätstheorie")

Albert Einstein changed the way physicists view the universe – and transformed the way we all see the world. Just over one hundred years ago, his Theory of Relativity stunned scientists, but today it is integral to modern thought as the most important scientific discovery of the twentieth century. In this unique single volume, Stephen Hawking has assembled the highlights of Einstein’s groundbreaking scientific work. Collected here are Einstein’s own illuminating writings on the Theory of Relativity, which present a world of paradoxes in which space is bent and time is curved. Yet Einstein was known not only for his landmark ideas in physics. Here too are his reflections on politics and religion, and his musings on the ultimate significance of his scientific findings.
