Oval

An oval (from Latin ovum, "egg") is a closed curve in a plane which "loosely" resembles the outline of an egg. The term is not very specific, but in some areas (projective geometry, technical drawing, etc.) it is given a more precise definition, which may include either one or two axes of symmetry. In common English, the term is used in a broader sense: any shape which reminds one of an egg.

The 3-dimensional version of an oval is called an ovoid.

Oval in geometry

The term oval when used to describe curves in geometry is not well-defined, except in the context of projective geometry. Many distinct curves are commonly called ovals or are said to have an "oval shape". Generally, to be called an oval, a plane curve should resemble the outline of an egg or an ellipse. In particular, the common traits that these curves have are:

Oval is a geographically small area of Kennington, south London, in the London Borough of Lambeth. It is situated 2.1 miles (3.38 km) to the south-east of Charing Cross. Oval straddles the border of south-west London and south-east London, and is where the postcode SE11 converges with the postcodes SW8 and SW9. Oval is best known for The Oval cricket ground, the home-ground of Surrey County Cricket Club.

Oval is within the borough constituency of Vauxhall. The Member of Parliament for the area is Kate Hoey of the Labour Party.

History

The land here was, from the seventeenth century, used for a market garden. The name "Oval" emerged from a street layout which was originated in 1790 but never completely built. The Montpelier Cricket Club leased ten acres of land from the Duchy of Cornwall in 1844, and Surrey County Cricket Club was formed soon thereafter at a meeting at the Horns Tavern (since demolished) on Kennington Park Road.

Oval (projective plane)

In mathematics, an oval in a projective plane is a set of points, no three collinear, such that there is a unique tangent line at each point (a tangent line is defined as a line meeting the point set at only one point, also known as a 1-secant). If the projective plane is finite of order q, then the tangent condition can be replaced by the condition that the set contains q+1 points. In other words, an oval in a finite projective plane of order q is a (q+1,2)-arc, or a set of q+1 points, no three collinear. Ovals in the Desarguesian projective plane PG(2,q) for q odd are just the nonsingular conics. Ovals in PG(2,q) for q even have not yet been classified. Ovals may exist in non-Desarguesian planes, and even more abstract ovals are defined which cannot be embedded in any projective plane.

Odd q

In a finite projective plane of odd order q, no sets with more points than q + 1, no three of which are collinear, exist, as first pointed out by Bose in a 1947 paper on applications of this sort of mathematics to statistical design of experiments.

Voice of America

The Voice of America (VOA) is the official external broadcast institution of the United States federal government. The VOA provides programming for broadcast on radio, TV, and the Internet outside of the U.S., in English and some foreign languages. A 1976 law signed by President Gerald Ford requires the VOA to "serve as a consistently reliable and authoritative source of news." The VOA Charter states: "VOA news will be accurate, objective and comprehensive." The Voice of America headquarters is located at 330 Independence Avenue SW, Washington, DC, 20237, U.S. The Voice of America is fully funded by the U.S. government. The United States Congress appropriates funds for it annually under the same budget for embassies and consulates.

VOA radio and television broadcasts are distributed by satellite, cable and on FM, AM, and shortwave radio frequencies. They are streamed on individual language service websites, social media sites and mobile platforms. The VOA has affiliate and contract agreements with radio and television stations and cable networks worldwide.

VOA (disambiguation)

The acronym VOA may refer to:

Voa is a Portuguese verb meaning "fly" or "flies", as in "I fly" or "it flies".

VOA (album)

VOA is the last solo album released by Sammy Hagar before he joined Van Halen. It is also his eighth solo studio album. The title is a reference to the Voice of America broadcast network.

Background and recording

According to the album's liner notes, "Burnin' Down the City" is inspired by the street artists of New York City.
