The General Theory of Relativity
Physik in unserer Zeit, 2020ALL of the previous considerations have been based upon the assumption that all inertial systems are equivalent for the description of physical phenomena, but that they are preferred, for the formulation of the laws of nature, to spaces of reference in a

Reciprocity principle and relative accelerations in the theory of relativity
American Journal of Physics, 2019It is proved that in the theory of relativity, the magnitudes of the relative accelerations of two observers with respect to each other can be unequal.

A meteoric expansion in esthetic medicine followed the introduction of nonsurgical cosmetic neuromodulators and fillers in the early 2000s, which has been recently declining.

Relative thinking theory [PDF]
Abstract The article presents a theory that I denote “Relative Thinking Theory,” which claims that people consider relative differences and not only absolute differences when making various economics decisions, even in those cases where the rational model dictates that people should consider only absolute differences. The article reviews experimental

Nature, 1938
IT is well known that the transformation theory of quantum mechanics corresponds to the property of the classical equations of motion of being invariant with respect to contact transformations. These are simultaneous transformations of co-ordinates xk (including time) and momenta pk (including energy), such that the difference of pkdxk in the old and ...

Nature, 1962
Two years ago I pointed out1 what appears to be an inconsistency in the kinematical part of Einstein's special theory of relativity. I repeated this in a slightly different form in a volume published in December last2. No comment has been made on the former publication, either spontaneously or in response to individual requests, and in none of the many

The theory of relativity, the electromagnetic theory and the quantum theory
Il Nuovo Cimento, 1958It is shown how it is possible, by means of geometry and the introduction of a principle of measurement, founded by analogy with the theory of H. Weyl, to discover a unity existing between gravitational, electromagnetic and quantum phenomena. Dirac’s equation and an extension of it are derived from the principle of measurement, and an essential feature

K-Theory, 1999
In 1990, Connes and Higson introduced the notion of asymptotic morphism of \(C^*\)-algebras. They showed that the bifunctor \(E(-,-)\), given on a pair \((A,B)\) of \(C^*\)-algebras by \[ E(A,B): =[[SA\otimes {\mathcal K},SB \otimes {\mathcal K}]], \] the group of homotopy classes of asymptotic morphisms between the stabilized suspensions of \(A\) and \
