Eccentricity



Eccentric is from the Greek language for ''out of the centre'', as opposed to concentric, ''in the centre''. * In mathematics, Eccentricity (mathematics) is a parameter associated with every conic section. It can be thought of as a measure of how much the conic section deviates from being circular. *For the eccentricity of a vertex in a graph, see Distance (graph theory) * In astrodynamics, the Eccentricity (orbit) can be calculated from orbital state vectors as an absolute value of eccentricity vector or using other methods based on orbital energy and angular momentum. * In mechanical engineering, an Eccentric (mechanism) is a wheel that rotates on an axle that is displaced from the focus of the circle described by the wheel —in other words, a mechanical motion that can operate either as a cam or a crank, depending upon how it is driven. * In sport, Eccentric (Sport) are those exercise movements involving the lengthening of muscle fibers. * In popular usage, Eccentricity (behavior) refers to unusual or odd behaviour on the part of a person, as opposed to being "normal (behavior)". There is a saying that "If you're rich, you're eccentric; if you're poor, you're crazy." See also List of people widely considered to be eccentric.

==Need a disambiguation page?== Can we have a disambiguation page for "Eccentricity" and move the "Popular usage" section to a different page? User:Kums 12:49, 14 Oct 2004 (UTC) Done: eccentricity (mathematics), eccentricity (orbit), eccentricity (mechanics), and eccentricity (behavior). User:JakeVortex 22:11, 3 Dec 2004 (UTC) ---- A simpler definition to visualize: The eccentricity of an ellipse is the ratio of the distance between the foci to the major axis. That other thing with the square root is very abstract. -User:P3d0 16:08, 27 Mar 2004 (UTC)
