	Pendulum - Encyclopedia, History, Geography and Biography
		The pendulum was discovered by Ibn Yunus al-Masri during the 10th century, who was the first to study and document its oscillatory motion.
		It is the vertical distance the pendulum fell.
		Pendulums (these may be a crystal suspended on a chain, or a metal weight) are often used for divination and dowsing.

		Real pendulums will also lose energy as they swing, and so their motion will be damped, with the size of the oscillation decreasing approximately exponentially with time.
		The case of a pendulum with a point mass swinging on a massless rigid rod of length l is the simple gravity pendulum (simple pendulum).
		Pendulums (usually a crystal suspended on a chain) are often used for divination and dowsing.

	Pendulum - Wikipedia, the free encyclopedia
		A simple gravity pendulum or bob pendulum (plural pendulums or pendula), is a weight on the end of a rigid rod (or a string/rope), which, when given an initial push, will swing back and forth under the influence of gravity over its central (lowest) point.
		As first explained by M. Schuler in his classic 1923 paper, a pendulum whose period exactly equals the orbital period of a hypothetical satellite orbiting just above the surface of the earth (about 84 minutes) will tend to remain pointing at the center of the earth when its support is suddenly displaced.
		This is the basic principle of Schuler tuning that must be included in the design of any inertial guidance system that will be operated near the earth, such as in ships and aircraft.

	Chaos theory - Encyclopedia, History, Geography and Biography
		For instance, in a system describing a pendulum, the phase space might be two-dimensional, consisting of information about position and velocity.
		A pendulum at rest will be plotted as a point, and one in periodic motion will be plotted as a simple closed curve.
		The Lorenz attractor is perhaps one of the best-known chaotic system diagrams, probably because not only was it one of the first, but it is one of the most complex and as such gives rise to a very interesting pattern which looks like the wings of a butterfly.

		In airplane operations during a turn if the combination of gravity and centrifugal force will cause a pendulum to swing toward the outside of the turn the airplane is said to be in a skid (if toward the inside, the condition is called a slip).
		In automobile and similar vehicle operations a loss of traction during braking or turning on either both front wheels, or both rear wheels, or all four wheels is called a skid.

		The political coalition of labor unions, minorities, liberals, and southern whites (the New Deal Coalition) allowed the Democrats to control the government for much of the next 30 years, until the issue of civil rights divided conservative southern whites from the rest of the party (see Dixiecrat).
		The political pendulum swung away from the Democrats with the election of Republican president Ronald Reagan in 1980.
		By 1980 the country was ready for a change in political vision after a decade of poor economic performance and several embarrassments abroad including the Vietnam War and the Iranian hostage crisis at the end of the Carter presidency.

	Oscillation - Enpsychlopedia
		Oscillation is the periodic variation, typically in time, of some measure as seen, for example, in a swinging pendulum.
		For example, two pendulum clocks mounted on a common wall will tend to synchronise.
		The apparent motions of the individual oscillations typically appears very complicated but a more economic, computationally simpler and conceptually deeper description is given by resolving the motion into normal modes.

	MACHINE TRANSLATION: A CONTRASTIVE LINGUISTIC PERSPECTIVE
		This required the achievement of three main computational linguistic tasks: (1) the development of an Arabic parser; (2) the development of a lexical-semantic processor; (3) the development of an automatic generator of the vowelized text.
		For example, the morphological processor was slimmed down to be used as an English stammer (to extract the stem of inflected word forms), the shallow understander was slimmed down to an efficient English parser, and the lexical-semantic disambiguated was tailored to handle types of ambiguities encountered in English.
		Indeed the pendulum has switched sides to the extent that it has reached the other extreme of viewing the whole language within the lexicon itself.

		Wittgenstein, Sellars, and Quine swung the philosophical clock so violently that the pendulum broke, to the point where some philosophers now question whether the clock even exists.
		What is needed is an alternative conception to what is now popular, but goes further in doing what rarely historically has happened before, which is to make an honest and stringent attempt to incorporate the insights that led these thinkers to their radical views.
		Any alternative must go forward, and the best way to begin is to start by disambiguating the fundamental concepts of philosophy, those that are requisite for any philosophical theory, those taken as presuppositions of which are methodologically relied upon for everything but given only slight attention in any critical analysis themselves.
