Remarks on the Theory of Relativity (1922)

open access: yesJournal of French and Francophone Philosophy, 2020
On April 22, 1922, the Societé française de Philosophie hosted Albert Einstein for a discussion of the theory of relativity.  In the course of this discussion, Henri Bergson, who was at that time writing Duration and Simultaneity, which explored some of ...

A Glimpse of Special Theory of Relativity [PDF]

open access: yes, 2017
This article provides a brief outline of Special Theory of Relativity. The physics before the relativity, the special relativity in itself, and the consequences of special relativity are discussed ...

Is the geopotential directly measurable [PDF]

open access: yesGeodetski Glasnik, 2016
It has been pointed out by the great Swedish geodesist Arne Bjerhammar and others around1985 that it is possible to replace the classical method of spirit leveling for determining differences of the geopotential by a much more direct and elegant method ...

Shape Dynamics [PDF]

open access: yes, 2013
Barbour's formulation of Mach's principle requires a theory of gravity to implement local relativity of clocks, local relativity of rods and spatial covariance. It turns out that relativity of clocks and rods are mutually exclusive.

Energy and Momentum densities of cosmological models, with equation of state $\rho=\mu$, in general relativity and teleparallel gravity

open access: yes, 2006
We calculated the energy and momentum densities of stiff fluid solutions, using Einstein, Bergmann-Thomson and Landau-Lifshitz energy-momentum complexes, in both general relativity and teleparallel gravity.

Adaptive mesh and geodesically sliced Schwarzschild spacetime in 3+1 dimensions

open access: yes, 1996
We present first results obtained with a 3+1 dimensional adaptive mesh code in numerical general relativity. The adaptive mesh is used in conjunction with a standard ADM code for the evolution of a dynamically sliced Schwarzschild spacetime (geodesic ...

What Is Information?: Why Is It Relativistic and What Is Its Relationship to Materiality, Meaning and Organization

open access: yesInformation, 2012
We review the historic development of concept of information including the relationship of Shannon information and entropy and the criticism of Shannon information because of its lack of a connection to meaning.

Down to earth relativity [PDF]

open access: yes, 1978
The basic concepts of the special and general theories of relativity are described. Simple examples are given to illustrate the effect of relativity on measurements of time and frequency in the near-earth ...

An Isotropic Cosmological Model with Aetherically Active Axionic Dark Matter

open access: yesUniverse
Within the framework of the extended Einstein–aether–axion theory, we studied the model of a two-level aetheric control over the evolution of a spatially isotropic homogeneous Universe filled with axionic dark matter. Two guiding functions are introduced,

From Modified Newtonian Dynamics to Superfluid Vacuum Theory

open access: yesEntropy, 2022
Herein is a review of the essentials of Modified Newtonian Dynamics (MOND) versus dark matter models based on Superfluids for modeling galactic rotation curves. We review the successes and issues of both approaches.
