Among other references to the book, a 2005 column of The Physics Teacher, included the work in a list of books "by and about Einstein that all physics teachers should have" and "should have immediate access to", [14] while a 2019 review of another work opened by stating: "Every teacher of General Relativity depends heavily on two texts: one ...
Translation by Megh Nad Saha in The Principle of Relativity: Original Papers by A. Einstein and H. Minkowski, University of Calcutta, 1920, pp. 1–34: :Introduced the special theory of relativity. Reconciled Maxwell's equations for electricity and magnetism with the laws of mechanics by introducing major changes to mechanics close to the speed ...
The term "theory of relativity" was based on the expression "relative theory" (German: Relativtheorie) used in 1906 by Planck, who emphasized how the theory uses the principle of relativity. In the discussion section of the same paper, Alfred Bucherer used for the first time the expression "theory of relativity" ( German : Relativitätstheorie ).
In special relativity, energy is closely connected to momentum. In special relativity, just as space and time are different aspects of a more comprehensive entity called spacetime, energy and momentum are merely different aspects of a unified, four-dimensional quantity that physicists call four-momentum. In consequence, if energy is a source of ...
The original 1920 English publication of the paper. Relativity: The Special and the General Theory (German: Über die spezielle und die allgemeine Relativitätstheorie) began as a short paper and was eventually published as a book written by Albert Einstein with the aim of explaining the theory of relativity.
In the preface to Relativity: The Special and the General Theory, Einstein said "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 ...
Leonardo reviewer Nan Conklin stated that the work is "not simply a book explaining Einstein's scientific work, but a mixture of history, politics and science." [ 1 ] According to Science for the People reviewer Paul Thagard , "Einstein's work is related," in this book, "to the rise of electrical industries and the later development of the ...
1. First postulate (principle of relativity) The laws of physics take the same form in all inertial frames of reference.. 2. Second postulate (invariance of c) . As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body.
