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.

Rose

A rose (/ˈroʊz/) is a woody perennial flowering plant of the genus Rosa, in the family Rosaceae. There are over 100 species and thousands of cultivars. They form a group of plants that can be erect shrubs, climbing or trailing with stems that are often armed with sharp prickles. Flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.

The name rose comes from French, itself from Latin rosa, which was perhaps borrowed from Oscan, from Greek ρόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd- (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr.

Rose (symbolism)

Roses have been long used as symbols in a number of societies. Roses are ancient symbols of love and beauty. "Rose" means pink or red in a variety of languages (such as the Romance languages and Greek).

The Classical Era

The rose was sacred to a number of goddesses including Isis, whose rose appears in the late classical allegorical novel The Golden Ass as "the sweet Rose of reason and virtue" that saves the hero from his bewitched life in the form of a donkey. The ancient Greeks and Romans identified the rose with the goddess of love, Aphrodite (Greek name) and Venus (Roman name).

In Rome a wild rose would be placed on the door of a room where secret or confidential matters were discussed. The phrase sub rosa, or "under the rose", means to keep a secret — derived from this ancient Roman practice.

Islam and Sufism

The cultivation of geometrical gardens, in which the rose has often held pride of place, has a long history in Iran and surrounding lands. In the lyric ghazal, it is the beauty of the rose that provokes the longing song of the nightingale - an image prominent, for example, in the poems of Hafez.

Rose (singer)

Keren Meloul better known as Rose (born in Nice on 24 May 1978) is a French singer, songwriter, author and composer.

After studying law, she became a school teacher teaching at the Jewish Merkaz Ohr Joseph in the 19e arrondissement of Paris before launching into music. She gained fame in 2006 with the single "La Liste" followed by a similarly titled album. She got a great boost when French singer Alain Souchon invited her to open for him at l'Olympia de Paris and at Zénith de Paris in 2006. In 2007 she started her own tour and appeared at La Cigale, a second time at l'Olympia as first part of her husband Bensé's concert and in Montreal in 2008.

In 2009, she recorded her second album Les Souvenirs sous ma frange produced by Jérôme Plasseraud and Thibaut Barbillon, both members of the group 1973. In 2013 she followed that up with a third album Et puis juin.

In addition, she has written songs for other artists, notably for Jenifer, appeared in a charity single for Les voix de l'enfant, project of La Fondation Abbé Pierre and in Sidaction in a duet with Alain Souchon. She also took part in album We Love Disney with the song "Au bout du rêve".
