Work of art

A work of art, artwork, art piece, piece of art or art object is an aesthetic physical item or artistic creation. Apart from "work of art", which may be used of any work regarded as art in its widest sense, including works from literature and music, these terms apply principally to tangible, portable forms of visual art:

Used more broadly, the term is less commonly applied to:

Works (Pink Floyd album)

Works is a Pink Floyd compilation album released in 1983. It features a variety of material, such as (among others) the band's early singles, "Arnold Layne" and "See Emily Play", alternative mixes of tracks from The Dark Side of the Moon, and the previously unreleased track, "Embryo".

Release and contents

The album was released by their former American label, Capitol Records, to compete with their then-current album The Final Cut. The main interest for collectors is the track "Embryo", an outtake from Ummagumma that later became a concert staple in a greatly elongated form, which originally only appeared in January 1970 on a scarce various artists compilation album promoting Pink Floyd's UK label Harvest Records entitled Picnic – A Breath of Fresh Air. Also unique to Works, the tracks "Brain Damage" and "Eclipse" are presented as alternate versions, possibly stereo mixes from the master tapes of the quadraphonic edition of The Dark Side of the Moon.

Factory-backed

In motorsports, a factory-backed racing team or driver is one sponsored by a vehicle manufacturer in official competitions. As motorsport competition is an expensive endeavor, some degree of factory support is desired and often necessary for success. The lowest form of factory backing comes in the form of contingency awards, based upon performance, which help to defray the cost of competing. Full factory backing can be often seen in the highest forms of international competition, with major motorsport operations often receiving hundreds of millions of euros to represent a particular manufacturer.

One-make series can also be backed by the factory, notably Ferrari Challenge and Porsche Supercup purely to allow themselves sell their competition specials of their models to customers and to organize series. These series commonly offer prize money and even sometimes a factory drive to an upper lever series.

In lower level racing, support from dealerships and importers may also be referred to as factory backing. In drifting, where factory backed teams are few and far between (Mopar and Pontiac of Formula D for example), works team/drivers are those backed by large or highly established tuning companies, as opposed to those entered by the drivers themselves or smaller and less well-off tuning companies. The advantage to this is drivers can get access to expensive prototype parts provided by the company that are not yet available to customers and in the event of their car being too badly damaged to compete, a back-up car will be available to them.

Dune

In physical geography, a dune is a hill of sand built by either wind or water flow. Dunes occur in different shapes and sizes, formed by interaction with the flow of air or water. Most kinds of dunes are longer on the windward side where the sand is pushed up the dune and have a shorter "slip face" in the lee of the wind. The valley or trough between dunes is called a slack. A "dune field" is an area covered by extensive sand dunes.

Some coastal areas have one or more sets of dunes running parallel to the shoreline directly inland from the beach. In most cases, the dunes are important in protecting the land against potential ravages by storm waves from the sea. Although the most widely distributed dunes are those associated with coastal regions, the largest complexes of dunes are found inland in dry regions and associated with ancient lake or sea beds.

Dunes can form under the action of water flow (fluvial processes), and on sand or gravel beds of rivers, estuaries and the sea-bed.

The modern word "dune" came into English from French circa 1790.

Arrakis

Arrakis (/əˈrækᵻs/;Arabic: الراقص‎, ar-rāqiṣ, "the dancer") — informally known as Dune and later called Rakis — is a fictional desert planet featured in the Dune series of novels by Frank Herbert. Herbert's first novel in the series, 1965's Dune, is popularly considered one of the greatest science fiction novels of all time, and it is sometimes cited as the best-selling science fiction novel in history.

In Dune, the planet is the home of the Fremen (Zensunni wanderers), and subsequently is the Imperial Capital of the Atreides Empire. Arrakis is the third planet orbiting the star Canopus, and it in turn is orbited by two moons, one of which has the image of the desert kangaroo mouse, Muad'Dib, on it; the other moon possesses the image of a human hand.

Environment and the spice

A desert planet with no natural precipitation, in Dune it is established that Arrakis had been "His Imperial Majesty's Desert Botanical Testing Station" before the discovery of melange, for which it is the only natural source in the universe. Melange (or, "the spice") is the most essential and valuable commodity in the universe, as it extends life and makes safe interstellar travel possible (among other uses). The planet has no surface water bodies, but open canals called qanats are used "for carrying irrigation water under controlled conditions" through the desert. The Fremen collect water in underground reservoirs to fulfill their dream of someday terraforming the planet, and pay the Spacing Guild exorbitant fees in melange to keep the skies over Arrakis free of any satellites which might observe their efforts. As indicated by its large salt flats, Arrakis once had lakes and oceans; Lady Jessica also notes in Dune that wells drilled in the sinks and basins initially produce a "trickle" of water which soon stops, as if "something plugs it."

Dune (crater)

Dune is a feature on Earth's Moon, a crater in the Hadley–Apennine region. Astronauts David Scott and James Irwin visited the south rim of it in 1971, on the Apollo 15 mission, during EVA 2. The south rim of Dune was designated Geology Station 4 of the mission.

Dune is located about 1.8 km east of Hadley Rille, less than 1 km south of the smaller Earthlight crater, and about 3 km south of the Apollo 15 landing site itself.

The crater was named by the astronauts after the novel by Frank Herbert, and the name was formally adopted by the IAU in 1973.

Samples

The following samples were collected from Dune Crater (Station 4), as listed in Table 5-II of the Apollo 15 Preliminary Science Report. Sample type, lithology, and description are from Table 5-IV of the same volume.

Samples 15470 to 15476 were collected near where the rover was parked to the south of the rim of Dune. Samples 15485, 15486, and 15499 were collected from the largest boulder in the photograph above. Sample 15498 was collected nearby.
