Two of the great mysteries of physics are the origin of mass, and the mysterious mass ratio between the proton and electron of ~1836. In this paper it is shown that the mass-energy of the proton is equivalent to the vacuum energy excluded by a spherical shell with an average radius ...

resonance ion storage technique allows cyclotron resonances for both electrons and protons, alternately trapped in the same magnetic well, to be compared in order to yield the proton-electron mass ratio m p/ m e = 1836.152470(76). The 41 p.p.b. uncertainty primarily reflects a systematic ...
1 Introduction: the brief history of mass One of the first attempts that we know of a fundamental theory, including the concept of mass, is attributed to ancient Greeks. In their four-elements theory, the massive elements were Earth and Water, while Air and Fire were massless. The modern ...
The experimental mass ratio of proton and electron is 1836. Nobody knows why it has to be this number. Sir Arthur Eddington did a lot of research on magic numbers of physics. But he did not succeed. One of the magic numbers is the fine-structure constant and another is the ...
(The nucleus of the ordinary hydrogen atom is an exception, containing only one proton and no neutrons.) Like opposite ends of amagnetthat attract one another, the negative electrons are attracted to a positive force, which binds them to the nucleus. The nucleus is small anddensecompared with...
Proton and Electron Mass-Energy Equivalence to Displaced Vacuum Energy By: Ray Fleming Abstract Two of the great mysteries of physics are the origin of mass, and the mysterious mass ratio between the proton and electron of ~1836. In this paper it is shown that the mass-energy of the proton...
It has no known substructure and is believed to be a point particle. An electron has a mass that is approximately 1836 times less than that of the proton. The intrinsic angular momentum (spin) of the electron is a half integer value of 1/2, which means that it is a fermion. The ...
