Ellipse \El*lipse"\ ([e^]l*l[i^]ps"), n. [Gr. 'e`lleipsis, prop., a defect, the inclination of the ellipse to the base of the cone being in defect when compared with that of the side to the base: cf. F. ellipse. See Ellipsis.]
(Geom.) An oval or oblong figure, bounded by a regular curve, which corresponds to an oblique projection of a circle, or an oblique section of a cone through its opposite sides. The greatest diameter of the ellipse is the major axis, and the least diameter is the minor axis. See Conic section, under Conic, and cf. Focus.
(Gram.) Omission. See Ellipsis.
-

The Sun flies forward to his brother Sun; The dark Earth follows wheeled in her ellipse.
--Tennyson.
Douglas Harper's Etymology Dictionary
1753, from French ellipse (17c.), from Latin ellipsis "ellipse," also, "a falling short, deficit," from Greek elleipsis (see ellipsis). So called because the conic section of the cutting plane makes a smaller angle with the base than does the side of the cone, hence, a "falling short." The Greek word was first applied by Apollonius of Perga (3c. B.C.E.). to the curve which previously had been called the section of the acute-angled cone, but the word earlier had been technically applied to a rectangle one of whose sides coincides with a part of a given line (Euclid, VI. 27).
Wiktionary
n. (context geometry English) A closed curve, the locus of a point such that the sum of the distances from that point to two other fixed points (called the focus of the ellipse) is constant; equivalently, the conic section that is the intersection of a cone with a plane that does not intersect the base of the cone. vb. (context grammar English) To remove from a phrase a word which is grammatically needed, but which is clearly understood without having to be stated.
WordNet
n. a closed plane curve resulting from the intersection of a circular cone and a plane cutting completely through it; "the sums of the distances from the foci to any point on an ellipse is constant" [syn: oval]
Wikipedia
In mathematics, an ellipse is a curve in a plane surrounding two focal points such that the sum of the distances to the two focal points is constant for every point on the curve. As such, it is a generalization of a circle, which is a special type of an ellipse having both focal points at the same location. The shape of an ellipse (how 'elongated' it is) is represented by its eccentricity, which for an ellipse can be any number from 0 (the limiting case of a circle) to arbitrarily close to but less than 1.
Ellipses are the closed type of conic section: a plane curve resulting from the intersection of a cone by a plane. (See figure to the right.) Ellipses have many similarities with the other two forms of conic sections: parabolas and hyperbolas, both of which are open and unbounded. The cross section of a cylinder is an ellipse, unless the section is parallel to the axis of the cylinder.
Analytically, an ellipse may also be defined as the set of points such that the ratio of the distance of each point on the curve from a given point (called a focus or focal point) to the distance from that same point on the curve to a given line (called the directrix) is a constant. This ratio is called the eccentricity of the ellipse.
Ellipses are common in physics, astronomy and engineering. For example, the orbit of each planet in our solar system is approximately an ellipse with the barycenter of the planet-Sun pair at one of the focal points. The same is true for moons orbiting planets and all other systems having two astronomical bodies. The shapes of planets and stars are often well described by ellipsoids. Ellipses also arise as images of a circle under parallel projection and the bounded cases of perspective projection, which are simply intersections of the projective cone with the plane of projection. It is also the simplest Lissajous figure formed when the horizontal and vertical motions are sinusoids with the same frequency. A similar effect leads to elliptical polarization of light in optics.
The name, ἔλλειψις (élleipsis, "omission"), was given by Apollonius of Perga in his Conics, emphasizing the connection of the curve with "application of areas".

Ellipse is the third studio album from Grammy Award-winning British singer-songwriter Imogen Heap. After returning from a round the world writing trip, Heap completed the album at her childhood home in Essex, converting her old playroom in the basement into a studio. The album got its name from the distinctive elliptical shape of the house. The album's title was confirmed by Heap via her Twitter page on 25 April 2009, after being leaked onto the internet on 23 April. On 15 June, Heap confirmed that the album would be released on 24 August 2009 in the United Kingdom on Megaphonic Records and 25 August in the United States/Canada on RCA Victor Records. International release date was also 24 August.
Subject matter in the songs includes post break-up malaise ("Wait It Out"), domestic boredom ("Little Bird"), body image issues ("Bad Body Double") and a common Heap theme, unrequited love ("Swoon" and "Half Life").
Usage examples of "ellipse".
An adjoining peduncle described during the same time similar, though fewer, ellipses.
Mina Gelmann wagged an admonitory finger in the direction of the bobbing blue ellipse.
As will be seen, it was full of ellipses and was fragmentary in its character, though completely effective in fact: Know all men by these Presents, et cetera, et cetera, et cetera.
On the next day it circumnutated in a greater degree, describing four irregular ellipses, and by 3 P.
Although the main petiole is continually and rapidly describing small ellipses during the day, yet after the great nocturnal rising movement has commenced, if dots are made every 2 or 3 minutes, as was done for an hour between 9.
In several other cases, for instance, when a leaf after describing during the day one or more fairly regular ellipses, zigzags much in the evening, it appears as if energy was being expended, so that the great evening rise or fall might coincide with the period of the day proper for this movement.
The most complex of all the movements performed by sleeping plants, is that when leaves or leaflets, after describing in the daytime several vertically directed ellipses, rotate greatly on their axes in the evening, by which twisting movement they occupy a wholly different position at night to what they do during the day.
But if so, it must be assumed that a bright lateral light completely stops circumnutation, for a plant thus exposed moves in a straight line towards it, without describing any ellipses or circles.
It returned also in a zigzag line, and then circumnutated regularly, describing three large ellipses during the remainder of the day.
There can be little doubt that it would ultimately have become upright by describing an additional number of irregular ellipses, one above the other.
If you go once around the epicycle while the deferent rotates once, you trace out the ellipse.

The pilot had wonn a crown of sorts: an ellipse of gold studded with gems half-covered its long, capacious skull.
The main petiole of a leaf having been secured to a stick, close to the base of the subpetiole of the terminal leaflet, the latter described two small ellipses between 10.
The ellipse described on the 29th had its longer axis directed at nearly right angles to a line joining the two cotyledons.
