A New Permittivity of the Rotational Electric Field

Authors: Krishna Srinivasan
Comments: 6 Pages.

The electric field in Maxwell’s equations can be written as a sum of the rotational and the irrotational electric fields. In this paper, it will be shown that Maxwell’s equations is formulated such that the permittivity of the rotational electric field is set to 1.0, and the permittivity of the irrotational electric field is commonly denoted as \epsilon_r. Faraday’s law can be reformulated in a little more general equation, so that a non-unity permittivity of the rotational electric field is possible. Although only a theoretical formulation is proposed, a way by which the permittivity of the rotational electric field can be measured is discussed.

Theoretical Treatment on the Hydrostatic Stability of Ships (Part 1:) Stable Conditions for the Upright State

Authors: Tsutomu Hori, Manami Hori
Comments: 16 Pages, 6 Figures, 36 Equations, 27 References, 1 Appendix.

Published in the Bulletin of Nagasaki Institute of Applied Science in Japan, 2022 (December), Vol.62, No.2, Research Notes in Mathematical and Physical Science, pp.151~166.

In this paper, a theoretical treatment on the hydrostatic stability of ships is presented. As the simplest hull form, a columnar ship with rectangular cross-section, which is made of homogeneous squared timber with arbitrary breadth and arbitrary material, is chosen.

In the Part 1 of this theme, the conditions under which the ship is stable in the upright state with horizontal deck are analyzed by means of ship's hydrostatics. By doing so, the dependence of the stable conditions on the breadth and material of the ship will be clarified.

Full Free Motion of Celestial Bodies Around a Central Mass - Why do They Mostly Orbit in the Equatorial Plane?

Authors: Raul Fattore
Comments: 174 Pages.

When we look at planets with their moons, our solar system, or distant galaxies, we see, in general, that the secondary masses orbit around the central mass mostly at its equatorial plane. If this analysis is correct, then it gives the answer by demonstrating why this happens. It also demonstrates the spiral nature of the motion, as well as the real orbit trajectories under diverse conditions.

Dynamic Deformation of Earth and Motion Effects Caused by Universe’s Gravitational Field

Authors: Raul Fattore
Comments: 16 Pages.

The causes of dynamic deformation of Earth and motion effects induced by universe gravitational field and from neighbor celestial bodies is easily explained. In this analysis, there are several cases that show with clarity what accelerations produce what effect and in which amount. The differential equations of a force in space are derived for those of you who want to make heavy calculations.

Intensity of Electromagnetic Waves As a Function of Frequency, Source Distance and Aperture Angle

Authors: Raul Fattore
Comments: 14 Pages.

The energy transport in Electromagnetic Waves, calculated by means of the Poynting vector formula, might not yield to correct results, because it only gives an average energy on a surface. The result obtained here agrees to the famous Planck equation (E=hf). Moreover, a wave equation for the interference pattern produced by slit diffraction is obtained to easily calculate pattern intensities.

Authors: Hoa Van Nguyen
Comments: 08 Pages.

This article proposes three thought experiments that are devised to support the theory of the extended model of the electron : 1. Variability of the electric charge of the electron in variable magnetic field . 2. Spin & Radiation of the electron moving parallel to a time-varying magnetic field . 3. Experiment on diffraction of light to prove photons being electric dipoles and vice versa .

The Angular Momentum of a Solar System

Authors: Kay Zum Felde
Comments: 2 Pages.

The movement of planets orbiting the sun is proposed to be an acceleration and not a velocity. The movement of the plantes in a solar system is found to be follow the law of the sum of all angular momentums which should be zero.
