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.

Ice pop

An ice pop is a water-based frozen snack. It is also referred to as a popsicle (Canada, U.S.), freeze pop (Ireland, U.S.), ice lolly (United Kingdom, Ireland), ice block, icy pole (parts of Australia and New Zealand), or chihiro (Cayman Islands). It is made by freezing flavored liquid (such as fruit juice) around a stick, generally resembling a tongue depressor. Often, the juice is colored artificially. Once the liquid freezes solid, the stick can be used as a handle to hold the ice pop. When an ice pop does not have a stick, it is called, among other names, a freezie.

History

Frank Epperson of Oakland, California, popularized ice pops after patenting the concept of "frozen ice on a stick" in 1923. He initially called it the Epsicle. A couple of years later, Epperson sold the rights to the invention and the Popsicle brand to the Joe Lowe Company in New York City.

Epperson claimed to have first created an ice pop in 1905 at the age of 11 when he accidentally left a glass of powdered soda and water with a mixing stick in it on his porch during a cold night, a story printed on the back panel of Popscicle brand treat boxes in the 80's and 90's. However, the evidence for this is scant.
