Fish fin

Fins are usually the most distinctive features of a fish, composed of bony spines or rays protruding from the body with skin covering them and joining them together, either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported by muscles only. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes, such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lure prey, and triggerfish avoid predators by squeezing into coral crevices and using spines in their fins to lock themselves in place.

Fin

A fin is a thin component or appendage attached to a larger body or structure. Fins typically function as foils that produce lift or thrust, or provide the ability to steer or stabilize motion while traveling in water, air, or other fluid media. Fins are also used to increase surface areas for heat transfer purposes, or simply as ornamentation.

Fins first evolved on fish as a means of locomotion. Fish fins are used to generate thrust and control the subsequent motion. Fish, and other aquatic animals such as cetaceans, actively propel and steer themselves with pectoral and tail fins. As they swim, they use other fins, such as dorsal and anal fins to achieve stability and refine their maneuvering.

Generating thrust

Foil shaped fins generate thrust when moved, the lift of the fin sets water or air in motion and pushes the fin in the opposite direction. Aquatic animals get significant thrust by moving fins back and forth in water. Often the tail fin is used, but some aquatic animals generate thrust from pectoral fins. Fins can also generate thrust if they are rotated in air or water. Turbines and propellers (and sometimes fans and pumps) use a number of rotating fins, also called foils, wings, arms or blades. Propellers use the fins to translate torquing force to lateral thrust, thus propelling an aircraft or ship. Turbines work in reverse, using the lift of the blades to generate torque and power from moving gases or water.

Cities (Anberlin album)

Cities is the third studio album by American alternative rock band Anberlin, released on February 20, 2007. The songs "Godspeed" and "The Unwinding Cable Car" were released as singles with accompanying music videos. The album debuted at No. 19 on the Billboard 200.

Production

The band spent more than 40 days in the studio recording Cities and went back on tour on September 14 after listening to the finished work on the morning of September 13. Lead singer Stephen Christian kept fans posted on progress in the studio through the band's online forums. Anberlin asked fans to message their phone numbers to the band through their message board so they could call the fans and ask for advice on the album. The album was produced by Aaron Sprinkle, who also produced Anberlin's first two albums Blueprints for the Black Market and Never Take Friendship Personal.

Promotion and pre-release

In late 2006, the band started previewing content for the album in various ways. The song "Godspeed" was released as a single on December 28, 2006. The band started playing "Hello Alone" at concerts under its working title, "The Lesser Thans." Anberlin also posted individual song previews on MySpace and PureVolume.

Fin (disbanded)

Fin (not to be confused with British rock band Fin) were a British alternative rock band formed in 1993, who achieved mild success on the independent circuit in the UK.

Their initial release, "Headstrong", was financed by money received from the BBC, after the company used a video clip of a Fin song in a film version of the Roddy Doyle novel The Snapper. They toured regularly, including support slots for bands as diverse as Tindersticks and The Cranberries. Their debut album Positive (which was mainly a singles compilation) was well received by critics, but sold poorly and the band split up in 1997. In 2008, frontman Johnny Daukes returned with a new band, All Our Good Friends.

Ray (art magazine)

Ray was a British short-run little avant-garde art magazine, designed, edited, and financed by the English artist and designer Sidney Hunt (1926 - 1927), and described as the English equivalent of other influential art journals from the 1920s such as Merz, Mecano and De Stijl.Ray featured work of leading figures of the European avant-garde such as Kurt Schwitters, El Lissitzky, Theo van Doesburg, Naum Gabo, and Hans Arp. Although only two issues were printed, the existence of Ray establishes a line of continuity between the Vorticist movement of the 1910s and Unit One's renaissance of British art in the 1930s. From this perspective, Ray should be considered the missing link between the 1914-15 publication of the Vorticist journal BLAST and the edition of the abstract and constructivist English magazines Axis (1935-37) and Circle (1937).
