What gauges can be used in applied electromagnetic calculations?
Vladimir Onoochin
In the classical electrodynamics, different gauges, i.e. connections between the electromagnetic potentials, are used. Some of these are quite specific and intended for calculation…

Comment on work of Yang and Nevels "Direct, analytic solution for the electromagnetic vector potential in any gauge" (arXiv:2507.02104)
Vladimir Onoochin
In the Comment the procedure for obtaining a solution for the electromagnetic potential, presented in the cited work arxiv:2507.02104, is analyzed. It is shown that the solution ob…

Comment on work of Umrigar and Anderson "Energy needed to propel a tiny spacecraft to Proxima Centauri, and, an unstated assumption in Einstein's 1905 paper" (arXiv:2502.04331v1)
V. Onoochin
In a recent paper by Umrigar and Anderson, the authors make an important statement: it is possible to misunderstand the behavior of physical objects (parts of a spacecraft) if that…
