Ss. Santos, The interaction between classical physics and quantum mechanics on the experiments of mass variation and ultimate speed, PHYS ESSAYS, 11(3), 1998, pp. 357-360
An expression of energy far moving charges is deduced using classical physi
cs and quantum mechanics. The theoretic result is in agreement with the exp
eriments of Bertozzi (ultimate speed), Bucherer, and Neumann (mass variatio
n).
