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.

Global (cutlery)

Global (often written in all capitalized letters as GLOBAL) is a brand of cutlery products made by Yoshikin of Japan. Their selection of knives are known for their distinctive one piece, molybdenum/vanadium stainless steel design. These are considered premium level products with a single knife often costing upwards of $100 (USD). Global products can often be found at specialty cooking retailers.

Compared to conventional European knives such as PUMA,J. A. Henckels or Wusthof, Global knives are made from a significantly harder alloy of steel, use a thinner blade thickness, and are ground to a narrower angle. This produces an extremely sharp knife which keeps its edge longer and allows for more accurate work, but takes longer to sharpen when it becomes dull. Because of this, the manufacturer recommends using whetstones and ceramic sharpening rods as opposed to the European sharpening steel. In addition, Global knives are renowned for their surprisingly light weight and even balance, a trait achieved by hollowing out the handle during production.

Global (TV series)

Global, styled also as Global with Matthew Amroliwala (as of 8 September 2014), is a news programme on BBC World News that premiered on 14 January 2013 with the relaunch of the channel from Broadcasting House. The programme was hosted initially by Jon Sopel who joined the channel from the domestic BBC News channel. Sopel regularly presented the programme on location around the world and in this case it is broadcast in part on the BBC News channel. Sopel was promoted to North America Editor in 2014, and was succeeded in September by Matthew Amroliwala.

Global replaced The Hub, which originally was an edition of World News Today and served as a news 'nerve centre' for South Asia and the Middle East, providing both the headlines, and detailed analysis of the global news agenda.

Schedule

Global is aired from 15:00–16:30 GMT (16:00–17:30 BST in summer time), Monday to Friday on BBC World News, usually followed by an edition of World Business Report.

Presenters

When Jon Sopel presented, the title sequence ends by stating 'Global with Jon Sopel'. However, when he does not, as he is often on assignment, the titles only show 'Global', regardless of the replacement presenter. This only happens if he isn't reporting from a location on a topic covered in the show.
