We use a rovibrationally pure sample of ultracold KRb molecules to improve the measurement on the stability of electron-to-proton mass ratio ($\\\mu = \\\frac{m_{m e}}{M_{m p}}$). The measurement is based upon a large sensitivity coefficient of the molecular spectroscopy, which...
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...
Electrons behave both as particles and as waves, and their motion generates electric and magnetic fields. Though the electron is the lightest subatomic particle, its charge is as great as that of a proton. See more at atom. The American Heritage® Student Science Dictionary, Second Edition. ...
which is considered the basic unit ofelectric charge. The restmassof the electron is 9.1093837015 × 10−31kg, which is only1/1,836the mass of aproton. An electron is therefore considered nearly massless in comparison with a proton or aneutron, and the electron mass is not included in ...

The number of protons in an element determines its atomic number, Z. Hydrogen is the lightest element and has one proton (Z = 1); uranium is the heaviest naturally occurring element and has 92 protons (Z = 92). Each proton, which is assigned a mass of 1.00728 atomic mass units (amu)...

IT has recently been suggested by Bondi and Ly ttleton1,2 that the magnitudes of the electric charges on the proton and electron may differ by a little more than one part in 1018, in which case electrostatic forces would cause the universe to expand. In
