IT has recently been suggested by Bondi and Ly ttleton1,2that 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 fact, Piccard and Kessler3attempted ...

We know that the negative charge on the electron and the positive charge on the proton are equal.Suppose,however,that these magnitudes differ from each other by 0.00007%.With what force would two copper pennies,placed 1.2 m apart,repel each other?Assume that each coin contains 3 multiplied by...
interactions, which appears in all equations of microscopic electrodynamics. The elementary charge is exactly equal to the electric charge of the electron, proton, and nearly all other charged elementary particles, which by virtue of this fact are the material carriers of the smallest charge in ...
