**Abstract:**

Thirty-six summaries of research results in physics, are given. They reveal the relationships between electrostatic field and gravitation, between induction electric field, inertia and the relativistic mass-energy equivalence law. Aberration of electric field is featured to obtain radiation reaction force and radiation power of a charged particle accelerated by an electric field, leading to the explanation of speed of light c being a limit. It is shown that circular revolution of a charged particle, round a center of force of attraction, is stable, which leads to the introduction of two models of the hydrogen atom. A modification of Coulomb’s law, to include gravitation and radiation, makes relativity and quantum theories unnecessary. The contentious issue of aether, as a medium filling the universal space, is resolved with permittivity ε and permeability μ regarded as properties of electric fields composing the aether, supporting radiation at the speed of light. Relativistic and non- relativistic explanations of the results of some experiments are proffered. The importance of magnetic vector potential and Poynting vector, in the generation of electromagnetic waves, is treated. It is proposed that an electron of charge -e and mass m might be an impenetrable spherical shell of radius a, with intrinsic energy E = e^2/8πεa = 1⁄2mc^2. An electron and positron unite, without annihilation to form a neutral particle of mass m, with emission of radiation.
