special relativity

The physical theory of space and time developed by Albert Einstein, based on the postulates that all the laws of physics are equally valid in all frames of reference moving at a uniform velocity and that the speed of light from a uniformly moving source is always the same, regardless of how fast or slow the source or its observer is moving. The theory has as consequences the relativistic mass increase of rapidly moving objects, the Lorentz-FitzGerald contraction, time dilatation, and the principle of mass-energy equivalence. Also called special theory of relativity.


(ˌrɛl əˈtɪv ɪ ti)

1. the state or fact of being relative.
a. Also called special relativity. the first part of Einstein's two-part theory, based on the axioms that physical laws have the same form throughout the universe and that the velocity of light in a vacuum is a universal constant, from which is derived the mass-energy equation, E = mc2.
b. Also called general relativity. the second part, a theory of gravitation based on the axiom that the local effects of a gravitational field and of the acceleration of an inertial system are identical.
3. dependence of a mental state upon the nature of the human mind.

He does not formulate partial theories of special relativity, but by explaining Minkowski spacetime, provides a prolegomenon to the comprehension of partial theories of special relativity such as the mechanics of point particles, or of continua, electrodynamic, thermodynamic, and so on.
As a precursor to Einstein's Special Relativity Theory Maxwell had, a century earlier, established that light was an interaction between moving electricity and moving magnet and was an electromagnetic wave.
How is it possible that there is a first order difference in v/c in spacecraft range measurements, while at the same time there are many experiments on time dilation that are consistent with Special Relativity Theory to second order in v/c (see, for example, [10])?
The element of time was introduced by Einstein's professor and mathematician Hermann Minkowski who, after reading Einstein's early papers on his 1905 theory of special relativity, "revealed important symmetries in time and space" (Siegfried, 2002, pp.
Special relativity showed strange things like "moving clocks run slower, and moving objects are shorter" than everyday experience would suggest.
Einstein built special relativity on the principle that light's velocity was constant; he suspected that general relativity could be built on the principle that inertial and gravitational mass are equivalent.
The next section considers the arguments leading to special relativity as an example of false projection that, once recognized, may lead to world view changes.
The truth about the luminiferous ether and the basis for Einstein's special relativity can be arrived at by either of two rather different paths: I will call them the experimental and the theoretical paths.
Here, we stress that when we study accelerated motions Special Relativity can be formulated only for instantaneous inertial reference frames.
The researchers have exploited two different areas of physics: Einstein's special relativity - which interprets uniform motion between two objects moving at relative speeds - combined with the power of quantum theory, the new physics of the sub-atomic world that Einstein famously dismissed as 'spooky'.
Einstein's theory of Special Relativity (which has nothing to do with a favourite aunty, uncle, cousin or associated kin by the way) says time travelling into the future is as easy as lemon squeezy.
Einstein's famous paper on the electrodynamics of moving bodies, "Zur Elektrodynamik bewegter Korper" (1905) opened the theory of special relativity, which revealed that the Lorentz transformation inherent in the Maxwell equations can be derived from two simple postulates on motion: the relativity principle known since Galileo, and the invariance of the speed of light.
