Hexagonal prism

In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices.

Since it has eight faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces. Because of the ambiguity of the term octahedron and the dissimilarity of the various eight-sided figures, the term is rarely used without clarification.

Before sharpening, many pencils take the shape of a long hexagonal prism.

As a semiregular (or uniform) polyhedron

If faces are all regular, the hexagonal prism is a semiregular polyhedron, more generally, a uniform polyhedron, and the fourth in an infinite set of prisms formed by square sides and two regular polygon caps. It can be seen as a truncated hexagonal hosohedron, represented by Schläfli symbol t{2,6}. Alternately it can be seen as the Cartesian product of a regular hexagon and a line segment, and represented by the product {6}×{}. The dual of a hexagonal prism is a hexagonal bipyramid.

Hip (slang)

Hip is a slang term sometimes defined as fashionably current, and in the know. It has also been defined as "an attitude, a stance" in opposition to the "unfree world", or to what is square, or prude.

Hip, like cool, does not refer to one specific quality. What is considered hip is continuously changing.

Origin of term

The term hip is recorded in African American Vernacular English (AAVE) in the early 1900s. In the 1930s and 1940s, it had become a common slang term, particularly in the African-American dominated jazz scene.

Research and speculation by both amateur and professional etymologists suggest that "hip" is derived from an earlier form hep but that is disputed. Many etymologists believe that the terms hip, hep and hepcat derive from the west African Wolof language word hepicat, which means "one who has his eyes open". Some etymologists reject this, however, tracing the origin of this putative etymology to David Dalby, a scholar of African languages who tentatively suggested the idea in the 1960s, and some have even adopted the denigration "to cry Wolof" as a general dismissal or belittlement of etymologies they believe to be based on "superficial similarities" rather than documented attribution.

AB Pictoris

AB Pictoris (abbreviated AB Pic, also catalogued as HD 44627) is a K-type star, approximately 148 light-years away in the constellation of Pictor. It has been identified as a member of the young (30 million years old) Tucana–Horologium association. The star has also been classified as a BY Draconis variable. In 2005 it was announced that an astronomical object (AB Pictoris b, abbreviated AB Pic b) had been imaged in 2003 and 2004 close to and apparently in orbit around the star. Its mass suggests that it is at the borderline between being a brown dwarf or a planet.

Possible planetary system

In 2003 and 2004, an object (now catalogued as AB Pictoris b) was observed close to the star by a team of astronomers at the European Southern Observatory. Since it had common proper motion with AB Pictoris, it was concluded that it was physically close to the star. Its spectral type was estimated as between L0V and L3V. Using evolutionary models, its mass was estimated as from 13 to 14 Jupiter masses. However, because modelling such young objects is difficult, this estimate is very uncertain; some models give masses as low as 11 Jupiter masses or as high as 70 Jupiter masses. Temperature estimates range from 1600 K to 2400 K. As it is not known if the mass of the object exceeds the deuterium burning limit of 13 Jupiter masses, it is not clear whether the object should be classified as an extrasolar planet or a brown dwarf.

Splash! (UK TV series)

Splash! is a British television series that follows celebrities as they try to master the art of diving. The celebrities perform each week in front of a panel of judges and a live audience in an Olympic-size diving pool with the result each week partly determined by public vote. Gabby Logan and Vernon Kay present the show, whilst Team GB Olympic Bronze Medal winning diver Tom Daley is the expert mentor to the celebrities. It is filmed at the Inspire: Luton Sports Village, which is based in Stopsley, Luton. The show premiered on ITV on 5 January 2013 winning the ratings battle for its 7.15pm-8.15pm slot with an average audience of 5.6 million viewers, a network share of 23.6%, however, it was cancelled on 15 February 2014 after just two series.

The format for the show originated from the Celebrity Splash! franchise created by television production company Eyeworks in the Netherlands, and was broadcast on SBS 6 as Sterren Springen Op Zaterdag (Celebrities Jumping On Saturday).

Splash! (B'z song)

"Splash!" is the forty-second single by B'z, released on June 7, 2006. This song is one of B'z many number-one singles in Oricon charts. Splash! was re-recorded in 2012 with English lyrics and released as part of the band's iTunes-exclusive English album

Splash! (festival)

The Splash! Festival is one of Europe's biggest hip hop and reggae festivals. It used to take place at the Oberrabenstein reservoir near Chemnitz, Germany until 2006. In 2007 and 2008 the festival was held on the Pouch peninsula in Bitterfeld, Saxony-Anhalt. Since 2009 the Ferropolis in Gräfenhainichen is the ground for the Splash! festival.

The first Splash! took place in 1998 in the inner city of Chemnitz, in a former powerhouse. From 1999 on, it was hillside the Oberrabenstein reservoir.

In the early years there were two stages, one for hip hop, and one for reggae. In 2006, the festival had extended to six stages and four party tents. The hip hop stage is adjacent to the reservoir, visitors can see the concerts while bathing. The tents house, amongst hip hop and drum and bass DJs, dancehall and reggae sound systems, a graffiti contest and ITF matches.

The name "Splash" hints at the waterside location of the festival and the phrase "to make a splash".
