	ALGOL - Wikipedia, the free encyclopedia
		ALGOL (short for ALGOrithmic Language) is a family of imperative computer programming languages originally developed in the mid 1950s which became the de facto standard way to report algorithms in print for almost the next 30 years.
		ALGOL 60 allowed for two types of parameter passing: the common call-by-value, and the unique call-by-name, which has never again been adopted by any of its successor languages.
		ALGOL 68 was defined using a two-level grammar formalism invented by Adriaan van Wijngaarden and which bears his name.

	eSky: Algol
		The Arabs gave the name 'Algol' ('The Demon') to this blue dwarf star, almost certainly because it is one of the most variable stars in the sky.
		As Algol's yellow primary star is circled by its companion, the less massive blue star loses streamers of matter from its surface.

		Algol is an eclipsing binary star system 93 light-years away as determined by the Hipparcos satellite.
		Homer wrote of Algol in the Iliad: "...the Gorgon's head, a ghastly sight, deformed and dreadful, and a sight of woe".
		Algol varies in V magnitude from 2.1 at maximum to 3.4 at primary minimum, with a period of 2.867315 days; this period, however, is slowly lengthening.

	Algol.
		Algol changes its brightness, because it is an eclipsing binary - every 68 hours and 49 minutes the demon "blinks" for roughly 8 hours as the dimmer star of the pair passes between the brighter star and the earth.
		Algol is the most famous of the eclipsing variables and the only one known of in ancient times.
		Medusa (Algol), whose head Perseus is carrying under his left arm, was the youngest and most beautiful and she was also the only mortal one of the three.

	Algol
		But Algol is equally famed for the "Algol paradox." The higher the mass of a star, the shorter its lifetime, as its fuel is used so much faster.
		Matter then flows in from the large one (at a rate of around two hundred- millionths of a solar mass per year) to the small bright one, the effect directly observed through the stellar spectrum as the K giant is being stripped nearly to its core.
		Algol is no demon at all, but a true friend, teaching us how stars interact and die, the effects of which you can see from your own backyard with no telescope at all.

	Algol
		The USS Algol (AKA-54) was launched by the Moore Dry Dock Co., of Oakland, California, on February 17, 1943, for the maritime commission and christened as the James Baines.
		On June 11, 1991, the Algol was towed from the James River Fleet to Willmington, North Carolina, where she was prepared by Eagle Island Marine to be sunk as a reef.
		The Algol's towers, and funnel were burned off so her relief on the ocean floor would not cause a hazard to navigation.

	Algol
		Algol (β Per / β Persei / Beta Persei) is a bright star in the constellation Perseus.
		To be more precise, however, Algol happens to be a triple star system: the eclipsing binary pair is separated by only 0.062 AU, while the third star (Algol C) is at an average distance of 2.69 AU from the pair and the mutual orbital period is 681 days (1.86 years).
		Algol is 92.8 light years from Earth, however about 7.3 million years ago it passed within 9.8 light years.

		Algol 68 was defined in a formal document, first published in January 1969, and later published in Acta Informatica and also printed in Sigplan Notices.
		Algol 68 was the first major language for which a full formal definition was made before it was implemented.
		Another factor that hindered Algol 68 from spreading more widely is that Algol 68 was designed for programmers, not for compiler writers, in a time when the field of compiler construction was not as advanced as it is today.

	Algol, the Demon Star (Site not responding. Last check: 2007-11-07)
		Algol is bright, varying from 2nd magnitude to 3rd magnitude.
		Algol seems to get dimmer when the K star passes between the B star and the earth, blocking the B star's light.
		Algol also has a third star 1.5 times the mass and radius of the sun which orbits once in 1.86 years, and, as Kepler was clever enough to point out, the longer the orbit, bigger the orbit, so it's kind of out there doing its own thing.

	Shipwreck Algol
		The Algol seemed to be sinking quite slowly, but as soon asher stern was awash, she went down like a rock, with air pockets causing waterto be spouted out of her stern.
		We found the Algol to be sitting on a 45 degree angle on her port side.She was on a clean sand bottom in 120 feet of water.
		Algol (AKA-54) was laid down on 10 December 1942 at Oakland, Calif., by the Moore Dry Dock Co. under a Maritime Commission contract (MC hull 1153) as SS James Barnes; launched on 17 February 1943; sponsored by Mrs.

	AllRefer.com - Algol, in astronomy, Star (Astronomy: Stars) - Encyclopedia
		Algol's variation in apparent magnitude, from 2.06 to 3.28, is due to the fact that it is an eclipsing binary star, with one component revolving about the other with a period of 2 days, 20 hr, 49 min.
		Algol is of spectral class B8 V and is about 105 light-years from the earth.
		The name Algol comes from the Arabic Ras al Ghul, which means "demon's head," and the star is sometimes called the Demon Star.

	Hanoi: Algol-60
		ALGOL (ALGOrithmic Language) is one of several high level languages designed specifically for programming scientific computations.
		Although ALGOL never reached the level of commercial popularity of FORTRAN and COBOL, it is considered the most important language of its era in terms of its influence on later language development.
		ALGOL's lexical and syntactic structures became so popular that virtually all languages designed since have been referred to as "ALGOL - like"; that is they have been hierarchical in structure with nesting of both environments and control structures.

		Although ALGOL never became widely used, for the next 20 years it was the major language used for publishing and communicating algorithms.
		ALGOL is historically important to students because it introduced many new concepts.
		Also, since ALGOL was used as the only language for publishing algorithms for such an extended period of time, students should be familiar with ALGOL so that they will be able to read and understand important papers and publications from that time.

		With his arrival, the band is thus able to showcase the songs in an evolved form, having frequent harmonizations between the guitars.
		Andrea decides to keep the old monicker for the new band, and the old songs, put aside when old Algol split-up, begin to raise to a new life and vitality: in a few rehersals, some of them are exhumed and revamped (Chaos Embrace, Sleepy Hollow, Dumb And Blind, Oblivion, Through Time And Space).

		ALGOL is a programming language originally developed in the mid 1950s which became the de facto standard way to report algorithms in print for almost the next 30 years.
		Note: throughout its effective life, the name of the programming language ALGOL was always presented in all-uppercase letters, and this is the practice we've adopted here.
		The Burroughs Corporation's B5000 and its successors were stack machines designed to be programmed in an extended variant of ALGOL 60, known as Elliot ALGOL; indeed their operating system, or MCP as they are called, was written in Elliot ALGOL as far back as 1961.

		The binary nature of Algol was confirmed in 1889 by Hermann Carl Vogel (1841-1907) who found periodic Doppler shifts in the spectrum of Algol A (spectral class B8V), and the overlaying spectrum of the companion, Algol B, of type Am.
		Algol A and B form a close binary system, the actual eclipsing binary, separated by only 10.4 million km.
		Algol A is a white main-sequence star, while Algol B is believed to be a subgiant.

		In fact at the place of Algol in the picture of the constellation there is the head of the Medusa, which the Greek hero Perseus had killed with his mirror shield by her own look.
		Algol or beta Perseï is a multi star system 96 lightyears away with two main components, where the central star is a massive, bright, white blue main class star (B8) with 3.7 solar masses at 2.9 times solar diameter and a 100 times higher absolute brightness than our Sun.
		The nature of the Algol system were discovered through the spectroscopic analization of Algol's light applying the Doppler effect, postulated by Christian Andreas Doppler (1803-1853).
