About a third of a century ago, when Hertz's demonstration of the actual existence of those electrical waves predicted by Maxwell, was still so recent that the wonder of it was still und,ulled by familiarity, it was no uncommon experience to meet in the periodical literature of physics some new proo

It is shown how the essential features of the perturbations created in a dispersive medium by an external charge (namely screening, excitation, and their respective behavior in different velocity ranges), can be seen to have their origin in the ordinary response of one single oscillator to the field
A discussion of sound propagation in a moving #uid con"ned by cylindrical walls is presented. Based on the continuity equation and the Euler equation, a single &&exact'' ordinary di!erential equation in the acoustic pressure is derived for the case where the medium #ow v (r) depends on the radial co
