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.

Blinky (singer)

Sondra "Blinky" Williams (born May 21, 1944 in Oakland, California) is an American R&B and soul singer-songwriter.

Early life

Williams was born in Oakland, California, but later grew up in Los Angeles. The daughter of a pastor, she was active in church choirs since the age of six.

Career

She recorded the album "Hark The Voice" on Atlantic Records, then moved to Motown where she recorded (as "Blinky") five singles including her debut, the Ashford & Simpson penned single "I Wouldn't Change The Man He Is," (a song reportedly written about Lovin' Spoonful studio bass player James Killingsworth) in 1968, and thought she would find success when she recorded a duet album with Edwin Starr entitled "Just We Two" on the heels of his "Twenty-Five Miles".

However, they did not get the push that either the Marvin Gaye & Tammi Terrell or the Supremes-Temptations duets did, and success again eluded her when, after becoming a protégé of Sammy Davis, Jr., his deal with the label fell through.

LED art

LED Art is a form of light art constructed from light-emitting diodes. Many artists that use LEDs are guerrilla artists, incorporating LEDs to produce temporary pieces in public places. LEDs are very inexpensive to purchase and have become a new way to make street art. LEDs are, among others, used in installation art, sculptural pieces and interactive artworks.

Infamous LED Art

In early 2007, there was a bomb scare in Boston, Massachusetts in the United States caused by a guerrilla marketing campaign. An advertising firm working for Turner Broadcasting System Inc. to promote Aqua Teen Hunger Force, one of the network's animated television shows, hired two artists to produce art for the ad campaign. The artists placed LED signs featuring a character known as a Mooninite in various locations across 10 cities. However, Boston was the only city that reacted by shutting down bridges and bringing in bomb squads to remove the LEDs. The majority of the light boards were removed and the artists were arrested.
