The present work investigates the propagation of a radio pulse in an unmagnetized, statistically inhomogeneous plasma causing regular refraction and anisotropic scattering. Using the framework of geometrical optics, a Fokker-Planck equation is derived and integrated within a two-moment approximation. The method allows a continuous transition from weak to strong angular scattering and yields pul...

Among theories of the physical world, quantum mechanics remains a topic lively discussions on its so-called interpretation. For some it an open question to understand how deterministic equations this theory, as established long ago, may combine with fundamental uncertainty. We consider process spontaneous emission by atom interacting infinite number degrees freedom electromagnetic field. There ...
