Starting from the experimental fact that light propagates over a closed path at speed c, we show to what extent the isotropy of the speed of light can be considered a matter of convention. We prove the consistence of anisotropic and inhomogenous conventions, limiting the allowed possibilities. All conventions lead to the same physical theory even if its formulation can change in form. The mathe...

Recently Zangari and Censor discussed the non-uniqueness of the spatiotemporal world-view, and proposed a representative alternative based on the Fourier transform as a mathematical model. It was argued that this so called spectral representation, by virtue of the invertibility of the Fourier transform, is fully equivalent to our conventional spatiotemporal world-view, although in the two syste...

The article evaluates the influence of synchronous and asynchronous types learning in online environment on mastering a foreign language. field provides flexible efficient that makes it easy for students to form, explore learn information. author considers characteristic features learning, as well their joint, so-called hybrid use educational process. combines with an set electronic activities,...

The conventional nature of synchronisation is discussed in inertial frames, where it is found that theories using diierent synchronisations are experimentally equivalent to special relativ-ity. In contrary, in accelerated systems only a theory maintaining an absolute simultaneity is consistent with the natural behaviour of clocks. The principle of equivalence is discussed, and it is found that ...

This paper considers anew the simultaneity problem that arises when observations of transactions are used to study the demand behavior of pricetaking consumers. Simultaneity is shown to be a problem of censored outcomes. This fact is used to obtain a basic negative finding on identification in the absence of prior information on the structure of demand or the process of price determination. The...

Rotational time dilation and angular contraction are discussed in comparison with the time deletion and length contraction of special relativity. The related issues of clock paradox and simultaneity are explored in rotational scenario. The non Euclidian nature of a relativistic rotation is analyzed in both θ t and θ r subspace. It has been shown that the constancy of the speed of light is intri...
