Abstract

Thanks to Coulomb, we have measurable electrostatic and magnetic fields that stand alone. That is, when they are not in motion. Given motion, the two fields form a union - orthogonally to each other - which we call an electromagnetic field (e.m. for short). Nieto & Goldhaber, experimenters (among others), determined the approximate mass of these fields. (See Scientific American, May, 1976, The Mass of the Photon, by Nieto & Goldhaber) . As their experiment progressed over time, they refined their technique such that the result became progressively smaller - and eventually approached very close to the figure given here. There were anomalies of the curve caused by their examining other fields than the coulomb fields. These should be ignored.
