The book proposes a different definition of ether and the properties of magnetic charges, which differs from their historical presentation. Vortrons are the names of these periodically changing and self-propelled fast magnetic and slow gravitational charges. Vortrons are mechanical and electromagnetic microvichrons, macrovichrons, and hypervichrons. The products of microvichrons are elementary particles, their mass, charge and spin, nuclei of chemical elements, electrons, photons, thermal and sound phonons, etc.
