The concept of mass (mass, energy, relativity)
نویسنده
چکیده
Einstein's relation between the mass of a body and the energy contained in it is undoubtedly the most famous formula of the theory of relativity. It permitted a new and deeper understanding of the world that surrounds us. Its practical consequences are vast and, to a large degree, tragic. In a certain sense this formula has become the symbol of science in the 20th century. What is the need for yet another paper on this famous relation, on which thousands of papers and hundreds of books have already been written? Before I answer this question, let us think about the form in which, in your opinion, the physical meaning of the relation between mass and energy is most adequately expressed. Here are four relations:

On the Abuse and Use of Relativistic Mass
The concept of velocity dependent mass, relativistic mass, is examined and is found to be inconsistent with the geometrical formulation of special relativity. This is not a novel result; however, many continue to use this concept and some have even attempted to establish it as the basis for special relativity. It is argued that the oft-held view that formulations of relativity with and without ...
متن کاملPrinciple of the compressible fluid mechanics featured by ether non-viscosity and continuous medium
In the current optical theory, the moving mass of light quantum is usually studied as the basic mass where the photon energy is concerned. In the paper titled "The Relationship between light translation and fluctuation and ether energy and momentum", the relations between ether photon, energy of the ether field and its momentum can also be considered in light of the manifestation of the mass an...
متن کاملFundamental Disagreement of Wave Mechanics with Relativity
(This work has been copyrighted with the Library of Congress) A number of well-known difficulties in physics resulted from merging the theory of relativity with the Compton-de Broglie wave mechanics. Two such problems were the failure of Dirac’s relativistic wave equation to predict the correct velocity of the electron, and the fact that the measured yield from nuclear fission was found to be s...
متن کاملNew Version of General Relativity that Unifies Mass and Gravity in a Common 4D Higgs Compatible Theory
Recent enigmas of astrophysics such as dark energy or accelerating universe need to update General Relativity. A thorough examination of the original Einstein Field Equations (EFE) highlights three inconsistencies concerning the nature of spacetime. Here we solve these inconsistencies. As a consequence, this article proposes a Higgs compatible 4D expression of mass, m= f(x,y,z,t), and a new exp...
متن کاملAn Extended Interpretation of the Concept of Entropy Opening a Link between Thermodynamics and Relativity
It is well known that thermodynamics raises conceptual difficulties. Far to be limited to students having to learn the subject, this impression is sometimes mentioned by specialists themselves who confess not being totally sure of the consistency of the thermodynamic theory, despite the fact that its practical usefulness is indisputable. The present paper deals with this interesting question an...
