Einstein equivalence principle

Finally the results obtained will provide a resolution of the above-mentioned inconsistency between the Einstein equivalence principle and the relativity of acceleration. In conclusion, we will also bring up the non-participation of gravitational... 

Equivalence principles have always been and remain a hot topic. In typical disputes, one usually considers the so-called Einstein Equivalence Principle essentially stating that free fall and inertial motion are physically equivalent. In a more detailed argument, one distinguishes between weak, Einstein and strong equivalence principles, incorporating all effects from free fall to universal features of the theory of... 

Mossbauer resonance of Zn to study the influence of the gravitational field on electromagnetic radiation. A Ga ZnO source (4.2 K) was used at a distance of 1 m from an enriched ZnO absorber (4.2 K). A red shift of the photons by about 5% of the width of the resonance line was observed. The corresponding shift with Fe as Mossbauer isotope would be only 0.01%. The result is in accordance with Einstein s equivalence principle. Further gravitational red shift experiments using the 93.3 keV Mossbauer resonance of Zn were performed later employing a superconducting quantum interference device-based displacement sensor to detect the tiny Doppler motion of the source [66, 67]. 

The factors m cancel. (This is actually a very profound result called the equivalence principle the gravitational mass of a body equals its inertial mass. It is tbe starting point for Einstein s general theory of relativity.) One integration... 

By the Einstein mass-energy equivalence principle, the mass defect is the mass equivalent of the work done by the nuclear force in bringing the nucleons together to form the nucleus or, alternatively, of the loss of mutual potential energy of the nucleons as a result of their accretion. The energy... 

The second axiom, which is reminiscent of Mach s principle, also contains the seeds of Leibniz s Monads [reschQl]. All is process. That is to say, there is no thing in the universe. Things, objects, entities, are abstractions of what is relatively constant from a process of movement and transformation. They are like the shapes that children like to see in the clouds. The Einstein-Podolsky-Rosen correlations (see section 12.7.1) remind us that what we empirically accept as fundamental particles - electrons, atoms, molecules, etc. - actually never exist in total isolation. Moreover, recalling von Neumann s uniqueness theorem for canonical commutation relations (which asserts that for locally compact phase spaces all Hilbert-space representations of the canonical commutation relations are physically equivalent), we note that for systems with non-locally-compact phase spaces, the uniqueness theorem fails, and therefore there must be infinitely many physically inequivalent and... 

Abnormally high quantum yields may occur in photochemical reactions. Einstein s law of photochemical equivalence is the principle that light is absorbed by molecules in discrete amounts as an individual molecular process (i.e., one molecule absorbs one photon at a time). From optical measurements it is possible to determine quantitatively the number of photons absorbed in the course of a reaction and, from analyses of the product mixture, it is possible to determine the number of molecules that have reacted. The quantum yield is defined as the ratio of the number of molecules reacting to the number of photons absorbed. If this quantity exceeds unity, it provides unambiguous evidence for the existence of secondary processes and thus indicates the presence of unstable intermediates. 

Then, the principle of relativity simply states that all frames belonging to 5s are equivalent. Hence, in this limited context, Einstein s second postulate reduces to the statement that speed of electromagnetic radiation is a constant c in 5s. 

How the correspondence principle should be applied to an atomic system thus depends critically on whether or not there exists a multiperiodic representation of the classical trajectories - the question first raised by Einstein. If the system possesses multiperiodic orbits, then its motion becomes separable, i.e. it becomes equivalent to as many independent modes as there are degrees of freedom. Dynamical separability is assumed in all independent particle and perturbative models of the many-electron atom. It is, however, not strictly applicable and the successes of simple quantum theory for many-electron systems are, to say the least, surprising. It was pointed out by Einstein, who based his arguments on the work of Poincare [519], that there exists no true separation of the three-body problem. 

This is the basic principle of Einstein s special theory of relativity. However, Einstein was not content with the apparent absolute status conferred to accelerating frames by the behaviour of bodies within them. Einstein sought a general principle of relativity that would require all frames of reference, whatever their relative state of motion, to be equivalent for the formulation of the general laws of nature. In his popular exposition of 1916, Einstein explains this by describing the experiences of an observer... 

The second principle of photochemistry is called the photochemical equivalence law, or the Stark-Einstein law, which states the absorption of light occurs in the quantum unit of photon or one molecule absorbs one photon, and one or less molecule can be photolyzed accordingly. ... 

It should be noted that in 1911 Einstein had expanded his theoretical consideration of noninertial systems and had suggested the general relativistic theory of gravitation. On the basis of this theory Einstein postulated the principle of equivalence the action of a gravitational field is equivalent to the action of accelerated motion of a system. Corresponding mathematical expressions can be interpreted that any mass perturbs the enviromnental space therefore all bodies will move on the trajectories curved in a vicinity of the disturbing mass while approaching it.
