A. S. Eddington reached the conclusion that the value of the physical constant ch/2蟺eis given by the integer 136. His theory reduces the evaluation of this constant essentially to the counting up of symmetrical elements in a square array. The numbers of such elements in arrays arising in ...
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...
Electron mass refers to the mass of an electron, which is approximately 1/1836 times the mass of a proton. It is a fundamental property used in determining the mass density of matter systems. AI generated definition based on: Encyclopedia of Physical Science and Technology (Third Edition), 200...

Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 x 10^-27 kg, which is 1,836 times the mass of an electron. Protons, together with electrically neutral particles calle
can be generated by the loss of a proton or addition of a negatively charged moiety (such as a hydroxyl group). Ions may also be produced by removal of one or more electrons from a molecule using electron ionization (EI). This ionization method is historically the dominant ionization method...
proton is equivalent to the vacuum energy excluded by a spherical shell with an average radius equal to the charge radius of a proton. Likewise the electron mass is shown to be equivalent to the vacuum energy excluded by a spherical shell with an average diameter equal to the Compton ...

Neutron, neutral subatomic particle that, in conjunction with protons, makes up the nucleus of every atom except ordinary hydrogen (whose nucleus has one proton and no neutrons). Along with protons and electrons, it is one of the three basic particles ma
