e. In physics, the special theory of relativity, or special relativity for short, is a scientific theory of the relationship between space and time. In Albert Einstein 's 1905 paper, On the Electrodynamics of Moving Bodies, the theory is presented as being based on just two postulates: [p 1][1][2] The laws of physics are invariant (identical ...
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.
Einstein for Beginners, republished as Introducing Einstein, is a 1979 graphic study guide to Albert Einstein and the theory of relativity written by Joseph Schwartz and illustrated by Michael McGuinness. Leonardo reviewer Nan Conklin stated that the work is "not simply a book explaining Einstein's scientific work, but a mixture of history ...
The theory of relativity usually encompasses two interrelated physics theories by Albert Einstein: special relativity and general relativity, proposed and published in 1905 and 1915, respectively. [ 1 ] Special relativity applies to all physical phenomena in the absence of gravity. General relativity explains the law of gravitation and its ...
English: This file is the special relativity lecture of the Wikiversity:Special relativity and steps towards general relativity course. It is in pdf format for convenient viewing as a fullscreen, structured presentation in a classroom.
Lorentz factor. where and v is the relative velocity between two inertial frames. For two frames at rest, γ = 1, and increases with relative velocity between the two inertial frames. As the relative velocity approaches the speed of light, γ → ∞. Time dilation (different times t and t' at the same position x in same inertial frame)
Postulates of special relativity. 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 ...
Maxwell's equations were an essential inspiration for the development of special relativity. Possibly the most important aspect was their denial of instantaneous action at a distance. Rather, according to them, forces are propagated at the velocity of light through the electromagnetic field. [28]: 189.
