	The Bruce Medalists: Frank Dyson
		Frank W. Dyson, the son of a minister, won scholarships to secondary school and Cambridge University, where he studied mathematics and astronomy.
		Dyson spent his entire career, except for five years in Edinburgh, at the Royal Greenwich Observatory, where he was Astronomer Royal from 1910 - 33.
		Dyson is best known for directing (with Arthur Stanley Eddington) the 1919 eclipse expedition which confirmed the bending of starlight by the sun's gravity, as predicted by Einstein's general theory of relativity.

	Freeman Dyson
		Freeman John Dyson (born December 15, 1923) is an English-born American physicist and mathematician, famous for his work in quantum mechanics, nuclear weapons design and policy, and for his serious theorizing in futurism and science fiction concepts, including the search for extraterrestrial intelligence.
		Dyson conceived that such structures would be clouds of asteroid-sized space habitats, though science fiction writers have preferred a solid structure: either way, such an artifact is often referred to as a Dyson sphere, although Dyson himself used the term "shell".

		Born in 1868 near Ashby de la Zouche, Dyson was educated at Brandford and at the University of Cambridge, from whence, after a period of research, he was appointed as Chief Assistant at the Royal Observatory, Greenwich, by W. Christie in 1894.
		As arranged during Dyson's tenure, classification being strongly influenced by the practices of his precedessors G. Airy and W. Christie.
		There is much overlap between the records of Dyson's tenure as Astronomer Royal and those of his predecessor William Christie and even his predecessor George Airy [classmarks RGO 7 and RGO 6 respectively], and those of his cuccessor at Greenwich and Herstmonceux, Harold Spencer Jones [classmark RGO 8].

	BBC - h2g2 - Dyson Spheres
		Dyson swarms are the easiest to contemplate constructing as they can be put together over a long period of time.
		The main reason the Dyson sphere heats up to such high temperatures and the Earth doesn't is that the star heats up all the space inside of the sphere, so it's not just the shell, but the interior that heats up.
		Dyson said that there was enough matter in the planets and minor planets to make a 3m-thick shell around the sun at a distance of 1 AU.

		Sir Frank Watson Dyson (January 8 1868 – May 25 1939) was an English astronomer.
		However, the younger Dyson does credit Sir Frank with sparking his interest in astronomy; because they shared the same last name, Sir Frank's achievements were discussed by Freeman Dyson's family when he was a young boy.
		Inspired, Dyson's first attempt at writing was a 1931 piece of juvenilia entitled "Sir Phillip Robert's Erolunar Collision" — Sir Philip being a thinly disguised version of Sir Frank.

		Officially called the Greenwich Time Signal, the pips have been broadcast since 1924, and were the idea of the Astronomer Royal Sir Frank Watson Dyson and head of the BBC John Reith.
		The pips were originally controlled by two mechanical clocks located in the Royal Greenwich Observatory that had electrical contacts attatched to the pendulums.

		From 1957 to 1961 he worked on the Orion project, which proposed the possibility of space-flight using nuclear propulsion: a prototype was demonstrated using conventional explosives, but a treaty banning the use of nuclear weapons in space caused the project to be abandoned.

		The astronomer, Sir Frank Watson Dyson realized that the May 29th, 1919 total solar eclipse would provide the ideal opportunity.
		A cluster of stars, known as the Hyades, would pass near to the sun during this eclipse providing many bright stars to measure.
		Dyson planned two expeditions to observe the eclipse: one to the island of Principe, off the coast of Spanish Guinea in West Africa and one to Sobral in northern Brazil.

		His Majesty's Astronomer Royal, Sir Frank Watson Dyson revealed in London last week that Big Ben was not only one of the most famed, but, for an old clock, one of the most accurate of timepieces.
		After a 288-day comparison with the Royal Observatory at Greenwich (Astronomer Dyson's special charge) it was found that Big Ben's maximum deviation was only 1.4 sec.
		No intricate mechanical adjustments but a mere pocketful of small change maintains the accuracy of Big Ben.* "Whenever the clock is losing slightly," explained Astronomer Royal Dyson, "we just drop a ha'penny or a penny on a tray fixed about half way down the pendulum.
