absolute motion

absolute motion

[′ab·sə‚lüt ′mō·shən]
(navigation)
Motion relative to a point fixed on the earth's surface or to an apparently fixed celestial point.
(physics)
Motion of an object described by its measurement in a frame of reference that is preferred over all other frames.

The Fresnel drag effect is a phenomenological formalism that characterises the effect of the absolute motion of the propagation medium, say a dielectric, upon the speed of the EM radiation relative to that medium.
0] in [SIGMA]' is an absolute speed of non-detectable absolute motion is certain.
Corresponding to relations (3) and (4) in the contexts of absolute intrinsic motion and absolute motion, there are the intrinsic mass relation in the context of relative intrinsic motion (or in the context of intrinsic special theory of relativity ([phi]SR)) and mass relation in the context of relative motion (or in the context of SR).
This arrangement cannot detect the absolute motion of the solar system, as this contribution to the travel time difference cancels because of the geometry of the apparatus.
Although it is accepted knowledge that absolute motion through free space is undetectable, such motion is clearly suggested by the equations of modern physics as seen above.
Then in (12) [theta] is the azimuth of one arm relative to the local meridian, while [psi] is the azimuth of the absolute motion velocity projected onto the plane of the interferometer, with projected component [[upsilon].
We note that the relativistic features of the Dirac equation are consistent with the absolute motion of the wave function in the dynamical 3-space.
All eight experiments and theory show that we have both anisotropy of the speed of light and relativistic effects, and that a dynamical 3-space exists--that absolute motion through that space has been repeatedly observed since 1887.
The data from this experiment shows that De Witte had detected absolute motion of the earth through space, as had six earlier experiments, beginning with the Michelson-Morley experiment of 1887.
In 1991 Roland DeWitte working within Belgacom, the Belgium telecommunications company, accidently made yet another detection of absolute motion, and one which was 1st-order in v/c.
Physics textbooks assert that in the famous interferometer 1887 experiment to detect absolute motion Michelson and Morley saw no rotation-induced fringe shifts--the signature of absolute motion; it was a null experiment.
In addition, Harvard University's Song Zhang will present a geometry video acquisition system that measures absolute motions of both geometric shape and positions of deformable objects in real time to generate geometry videos and to find potential applications in various fields.
