    Abstract: A statistical strength criterion for brittle materials under static and repeated loadings is proposed. The criterion relates beginning of a macrofracture in the form of origination of microcracks to the moment at which the microcrack density in the material becomes critical. The idea of the criterion consists in identification of the values of micr... Show More

    Abstract: It is a basic, ancient and mysterious issue: why our space is three dimensional? This issue is related to philosophy, mathematics, physics and even religion, and thus aroused great research interests. The author makes an in-depth analysis of the problem, and finally comes to a conclusion: For any vector space with symmetry, orthogonality, homogenei... Show More
  • The General Equation of Motion in a Gravitational Field Based Upon the Golden Metric Tensor

    Abstract: In this paper, we used Howusu’s planetary equation. The general equation of motion is derived for particle of non-zero rest mass in a gravitational field based upon Riemannian geometry and the golden metric tensor which is thereby opens the way for further studies or to pave the way for applications such as planetary theory.

    Abstract: The ceramic sample of ScFeO3 (SFO) has been prepared by standard high temperature solid state reaction method using high purity oxides. The formation of the compound as well as structural analysis has been carried out by X-ray diffraction method which confirmed the rhombohedral symmetry with polar space group R3c. The average grain size obtained by... Show More

    Abstract: At present, it is believed that the Special Theory of Relativity (STR) is the only theory explaining the Michelson-Morley and Kennedy-Thorndike experiments. This article proved that another theory in accordance with these experiments is possible. In this article, we derive the new theory of kinematics of bodies from the universal frame of reference...

    Abstract: The initial state of the cosmos is analytically modeled as a radiation filled spherical cavity that expands from a singularity to later act as a clock and energy source in support of a 3-stage, radiation to a quark-hadron based, decoupling process. The model thereby avoids a need for Inflation and the presence of matter at start-up and during the r... Show More

    Abstract: A Lorentz force is generally exerted on a moving charged particle in an external magnetic field. But it is often asked whether also a neutral atom can feel a Lorentz force when moving straightly in an external magnetic field. It is shown that this is definitely not the case.
