English: A model of the field of physical activity published by Lundvall, S. & Schantz, P. 2013 in The Global Journal of Health and Physical Education Pedagogy 2(1):1-16. It was, in that study, used to describe the past and the future ingredients in the subject physical education in schools in Sweden from 1813 to present times.
Einstein sensed a conflict between Newtonian mechanics and the constant speed of light determined by Maxwell's equations. [6]: 114–115 Regardless of the historical and scientific issues described above, Einstein's early thought experiment was part of the repertoire of test cases that he used to check on the viability of physical theories.

Einstein's scientific publications are listed below in four tables: journal articles, book chapters, books and authorized translations. Each publication is indexed in the first column by its number in the Schilpp bibliography (Albert Einstein: Philosopher–Scientist, pp. 694–730) and by its article number in Einstein's Collected Papers.
In the following, the notation of Mansouri–Sexl is used. [2] They chose the coefficients a, b, d, e of the following transformation between reference frames: = + = = = where T, X, Y, Z are the Cartesian coordinates measured in a postulated preferred frame (in which the speed of light c is isotropic), and t, x, y, z are the coordinates measured in a frame moving in the +X direction (with the ...
The first of the classical tests discussed above, the gravitational redshift, is a simple consequence of the Einstein equivalence principle and was predicted by Einstein in 1907. As such, it is not a test of general relativity in the same way as the post-Newtonian tests, because any theory of gravity obeying the equivalence principle should ...
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.
