Paperback. Condición: Good. In 1905, a German technical journal, Annalen der Physik, published a remarkable paper by a young clerk in the patent office at Berne, Switzerland. The clerk was Albert Einstein. The paper outlined his Special Theory of Relativity, a revolutionary physical theory which discarded the concept of absolute motion in favor of relative motion in the context of a four-dimensional continuum of space-time. It proved to be the most profound revolution in physics since Newton.About ten years later, building on his earlier work, Einstein formulated the General Theory of Relativity in which he offered a new solution to the great problem of gravitation, postulating the non-Euclidean character of the space-time continuum. Together, the two theories constituted a radically reoriented way of looking at the physical universe, an approach that solved many of the unresolved difficulties of classical mechanics and paved the way for great advances in 20th-century physics. This concise volume contains two addresses by Dr. Einstein outlining aspects of the theories. Ether and Relativity (1920), delivered at the University of Leyden, discusses the properties demanded of the ether of space by the theory of relativity. Geometry and Experience (1921), given at the Prussian Academy of Sciences, describes the limits within which the Euclidean or any other practical geometric system can be held to be approximately true in connection with the concept of a finite universe.Both lectures are reprinted here complete and unabridged; both express elegant ideas in simple prose devoid of complicated equations or abstruse terminology; both offer scientists and laypeople unparalleled insight into the seminal thinking of the 20th century's greatest physicist.…

Paperback. Condición: Good. 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.…

Hardback. Condición: Very Good. BY W. H. MCREA, F. R. S. 'THE only justification for our concepts and system of concepts is that they serve to represent the complex of our experiences; beyond this they have no legitimacy. ' So Einstein writes on page 2 of this book. Most present-day physicists would agree, and many before Einstein must have held the same opinion. Einstein, however, put the opinion into practice to better purpose than any physicist before him. And for Einstein it evidently meant what it means for most of us today: a theory is the construction of a theoretical model of the world of physics; all the mathematical discussion applies to the model; the model embodies the 'system of concepts', and it serves 'to represent the complex of our experiences' if the experience of the theoretical observer in the theoretical model can be put into satisfactory correspondence with the experi- ence of the actual observer in the actual physical world. Classical mechanics and classical electromagnetism pro- vide models that are good representations of two sets of actual experiences. As Einstein was the first fully to appreciate, however, it is not possible to combine these into a single self-consistent model. The construction of the simplest possible self-consistent model is the achieve- ment of Einstein's theory of special relativity. The theory is found, in particular, to give a satisfactory representation of the electromagnetic interaction between charged particles through its use of the concept of the electromagnetic field.…
