The problem about "who is right in relativity and Newtonian mechanics" is analyzed and discussed, and the theoretical results described in this study are only used as reference. This study reveals that there is no contradiction between relativity and Newtonian mechanics, and the essence of the relativity lies in the mass energy equation.

Important Branch

The purpose of this paper is to show how the result of an erroneous experiment and the lack of understanding of the basic laws of Newtonian mechanics and its application diverted the progress of an important branch of theoretical physics from its true path and led to the creation of the theory of relativity (SR). Every year, many new papers regarding this theory are published that show its many contradictions and anomalies. This paper shows why Einstein's theory of relativity is theoretically and fundamentally incorrect and why, despite its problems, the theory gives some empirical predictions. A more logical solution based on Newtonian mechanics and on experiments and observations plus the concept of ether, leading to the same results, is proposed. As an example, mass-energy equivalence <mml:math display="inline"> <mml:mi>E</mml:mi> <mml:mo>≅</mml:mo> <mml:mi>m</mml:mi> <mml:msup> <mml:mrow> <mml:mi>c</mml:mi> </mml:mrow> <mml:mrow> <mml:mn>2</mml:mn> </mml:mrow> </mml:msup> </mml:math> is derived to show that Newtonian mechanics is adequate in the domain of high-speed particles. The derivation in this paper is by a similar technique to what has been previously published by the same author but with a different method of calculation. The paper also shows that SR does not explain, as claimed by Einstein, the null result of the Michelson and Morley experiment, which is the basis for the theory. It explains why the error in the experiment is hidden and difficult to detect. It also gives more information about the three previously published papers by the same author and endeavors to give a more comprehensive explanation as to what went wrong in this branch of theoretical physics.

Theoretical Results

The object of the paper is to indicate the value of theoretical investigations of hydrodynamic finite bearings under steady-state conditions. Methods of solution of Reynolds equation by both desk and digital computing, and methods of stabilizing the processes of solution, are described. The nondimensional data available from the solutions are stated. The outcome of an attempted solution of the energy equation is discussed. A comparison between some theoretical and experimental results is shown. Experimental methods employed and some difficulties encountered are discussed. Some theoretical results are given to indicate the effects of the inclusion of slip velocity, stabilizing slots, and a simple case of whirl.

Theory Of Fields

This book is an introduction to the modern methods of the general theory of relativity, tensor calculus, space time geometry, the classical theory of fields, and a variety of theoretical physics oriented topics rarely discussed at the level of the intended reader (mid-college physics major). It does so from the point of view of the so-called principle of covariance; a symmetry that underlies most of physics, including such familiar branches as Newtonian mechanics and electricity and magnetism. The book is written from a minimalist perspective, providing the reader with only the most basic of notions; just enough to be able to read, and hopefully comprehend, modern research papers on these subjects. In addition, it provides a (hopefully short) preparation for the student to be able to conduct research in a variety of topics in theoretical physics; with particular emphasis on physics in curved spacetime backgrounds. The hope is that students with a minimal mathematical background in calculus and only some introductory courses in physics may be able to study this book and benefit from it.

Quantum Interpretation

We know energy and mass of a particle can be connected by [Formula: see text]. What is the physical basis of this relation? Historically, it was thought to be based on the principle of relativity (PR). A careful examination of the literature, however, indicated that this understanding is not true. Einstein did not derive this relation from PR. Instead, his argument was mainly based on thought experiments, which focused on the similarity between radiation and matter. Following this hint, we suspect that the mass–energy equivalence could be based on the quantum property of wave–particle duality. We know photon and electron can behave as a particle as well as a wave. Such a wave property could make the particle behave differently from Newtonian mechanics. Indeed, using a wave model which treats particles as excitations of the vacuum, we show that the mass–energy equivalence relation can be directly derived based on the quantum relations of Planck and de Broglie. This wave hypothesis has several advantages; not only can it explain naturally why particles can be created in the vacuum; it also predicts that a particle cannot travel faster than the speed of light. This hypothesis can also be tested in experiment.

Good Agreement

A general THD theory and a comparison between theoretical and experimental results are presented. The generalized Reynolds equation, the energy equation in the film, and the heat transfer equation in the bush and the shaft are solved simultaneously. The cavitation in the film, the lubricant recirculation, and the reversed flow at the inlet are taken into account. In addition, the thermoelastic deformations are also calculated in order to define the film thickness. Good agreement is found between experimental data and theoretical results which include thermoelastic displacements of both the shaft and the bush.
