	Poynting-Robertson effect - Wikipedia, the free encyclopedia
		The Poynting-Robertson effect, also known as Poynting-Robertson drag, named after John Henry Poynting and Howard Percy Robertson, is a process by which solar radiation causes dust grains in a solar system to slowly spiral inward.
		Probably it is based on the Poynting article cited, which predates relativity theory and is "luminiferous aether"-based.

		John Henry Poynting (1852-1914), famous for his experiments on weighing the earth and the Poynting Vector in electromagnetic theory, set the standard for the School.
		Poynting had had an eye for the future and had introduced studies of radioactivity which continued under Smith, but it was the appointment of M L E Oliphant (1937-1950) which really established the Birmingham Physics Department as an international centre for Nuclear Research.
		Oliphant, Moon, Peierls and others were also involved in the Manhattan Project which constructed the first atomic bombs, indeed, Peierls and Otto Frisch wrote their well-known Memorandum at Birmingham in early 1940 demonstrating for the first time that such a bomb could be constructed using a relatively small quantity of separated Uranium-235.

	Fogal Transistor: Glossary Of Terms
		The intensity of this Poynting flux in the vicinity of a massive planet or sun changes the local energy density of the vacuum itself, increasing it in the vicinity.
		In turn that increases the Poynting S-flow from that potential acting as a dipole, because it increases the dipole strength and consequently the magnitude of the dipole's broken symmetry in its vacuum flux exchange.
		Any electric or magnetic charge, e.g., with a Poynting energy density flow impinging upon it, has excess "energy collection" or "energy collecting" upon it, due to the altered vacuum virtual photon flux that is now exchanging with it.
