Turn (geometry)

A turn is a unit of plane angle measurement equal to 2π radians, 360° or 400 gon. A turn is also referred to as a revolution or complete rotation or full circle or cycle or rev or rot.

A turn can be subdivided in many different ways: into half turns, quarter turns, centiturns, milliturns, binary angles, points etc.

Subdivision of turns

A turn can be divided in 100 centiturns or 1000 milliturns, with each milliturn corresponding to an angle of 0.36°, which can also be written as 21′ 36″. A protractor divided in centiturns is normally called a percentage protractor.

Binary fractions of a turn are also used. Sailors have traditionally divided a turn into 32 compass points. The binary degree, also known as the binary radian (or brad), is ¹⁄₂₅₆ turn. The binary degree is used in computing so that an angle can be represented to the maximum possible precision in a single byte. Other measures of angle used in computing may be based on dividing one whole turn into 2ⁿ equal parts for other values of n.

Turn (swimming)

In swimming, a turn is a reversal of direction of travel by a swimmer. A turn is typically performed when a swimmer reaches the end of a swimming pool but still has one or more remaining pool lengths to swim.

Again (T-ara EP)

Again is the fifth extended play by South Korean girl group T-ara, released on October 10, 2013 by Core Contents Media. It was the first album released after member Lee Areum left the group, and the first to feature the original six-member line-up since T-ara's debut.

Background and release

On October 6, 2013, T-ara announced the impending release of double lead singles to promote their upcoming EP, Again. The album was released digitally on October 10, including the singles "Number 9" (넘버나인) and "Because I Know" (느낌 아니까; Neukkim Anikka) and their music videos. "Number 9" is an electro-pop dance song with sad lyrics and melody. It was choreographed by Yama & Hotchicks, who also choreographed "Bo Peep Bo Peep". "Because I Know" is a mid-tempo song with an acoustic feel.

A repackaged edition of the EP, Again 1977, was released on December 4, 2013. It contains two new songs, "Again 1977" and "Do You Know Me", a remake of Sand Pebbles' 1977 hit, "What Should I Do". The EP was repackaged and digitally re-released again, on December 14, 2013, as White Winter with two Christmas songs, "Hide and Seek" and "Middle of Winter Hide and Seek".

Again (horse)

Again (foaled 22 May 2006) was an Irish Thoroughbred racehorse and broodmare. She was one of the leading Irish two-year-old fillies of 2008, when she won three of her five races including the Debutante Stakes and the Moyglare Stud Stakes. She recorded her most important win when taking the Irish 1,000 Guineas on her three-year-old debut, but was beaten in her three subsequent races.

Background

Again is a bay mare with a white blaze bred in Ireland by Southern Bloodstock, a breeding operation associated with the Coolmore Stud. She was sired by Danehill Dancer, the Leading sire in Great Britain & Ireland in 2009, whose other progeny have included Mastercraftsman and Choisir. Again's dam Cumbres, was an unraced half-sister of the multiple Group One winner Montjeu. During her racing career, the detail of Again's ownership changed from race to race: she was alternately described as being owned by Michael Tabor and by a partnership of Tabor and Susan Magnier. She was trained by David Wachman, the son-in-law of Coolmore's head John Magnier, at Goolds Cross in County Tipperary.
