Tunnel

A tunnel is an underground or underwater passageway, dug through the surrounding soil/earth/rock and enclosed except for entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.

A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in tunnel. Some tunnels are aqueducts to supply water for consumption or for hydroelectric stations or are sewers. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.

Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely.

Terminology

A tunnel is relatively long and narrow; the length is often much greater than twice the diameter, although similar shorter excavations can be constructed, such as cross passages between tunnels.

Tunnel (New York nightclub)

Tunnel was a nightclub in New York City, located at 220 Twelfth Avenue, in the Chelsea neighborhood of Manhattan, New York City, in the Terminal Warehouse Company Central Stores Building, which is now part of the West Chelsea Historic District. It operated from 1986 to 2001.

History and description

Tunnel, frequently misnamed as "The Tunnel", was opened in December 1986 at the cost of $5 million by Eli Dayan – the founder of Bonjour Jeans – in a space which was formerly a railroad freight terminal. Eli Dayan sold the property to Marco Riccota in January 1990. Peter Gatien acquired the 80,000-square-foot nightclub in 1992. The club was named for the tunnel-like shape of the main room, in which train tracks from the early 1900s ran through a sunken area of the dance floor. These were a relic of an era in which railroad sidings from the Eleventh Avenue freight line of the New York Central Railroad ran directly into warehouse buildings in that area, so that goods could be transferred to and from freight cars which were floated across the Hudson on barges from Hoboken.

Coil (band)

Coil was an English cross-genre, experimental music group formed in 1982 by John Balance—later credited as "Jhonn Balance"—and his life partner and collaborator Peter Christopherson, aka "Sleazy". The duo worked together on a series of releases before Balance chose the name Coil, which he claimed to be inspired by the omnipresence of the coil's shape in nature. Today, Coil remains one of the most influential and best-known industrial music groups.

The group's first official release as Coil was a 1984 12" album titled How to Destroy Angels released on the Belgian Les Disques du Crépuscule's sublabel LAYLAH Antirecords. Following the 12"s success, Some Bizarre Records produced two albums, Scatology, Horse Rotorvator and Coil departed SomeBizzare Label and Produced Love's Secret Domain, which met with little commercial success, but were praised as innovative due to their blend of industrial music and acid house.

In 1985, the group began working on a series of soundtracks, amongst them music for the first Hellraiser movie based on the novel The Hellbound Heart by their acquaintance at that time, Clive Barker. The group's first live performance in 16 years occurred in 1999, and began a series of mini-tours that would last until 2004. Following the death of John Balance on 13 November 2004, Christopherson announced via their official record label website Threshold House that Coil as an entity had ceased to exist.

Coil (album)

Coil is an album by Toad the Wet Sprocket released in 1997. It is their fifth studio album, and the final one before the band broke up in 1998. As with previous albums, Coil was released under the Columbia Records label and produced by Gavin MacKillop.

This album has been praised by some as the band's most mature album. It combines themes explored in all of their previous albums - including love, spirituality and the virtues of an uncomplicated life - and it continues the straightforward rock sound found in Dulcinea. One song from the album, "Come Down", hit the Billboard Modern Rock and Mainstream Rock Charts, and the single "Crazy Life" explores the perceived injustices experienced by Leonard Peltier. "Whatever I Fear" was also released as a single but failed to chart with poor backing from Columbia Records; thus in turn, the planned fourth single "Dam Would Break" was never released.

18 (number)

18 (eighteen) is the natural number following 17 and preceding 19.

In speech, the numbers 18 and 80 are sometimes confused. When carefully enunciated, they differ in which syllable is stressed: 18 /eɪtˈtiːn/ vs 80 /ˈeɪti/. However, in dates such as 1864, or when contrasting numbers in the teens, such as 17, 18, 19, the stress shifts to the first syllable: 18 /ˈeɪttiːn/. In some dialects, such as General American, there is little confusion because the single t sound in 80 becomes a d-like flap [ɾ], whereas the double t sound in 18 does not.

In mathematics

Eighteen is a composite number, its proper divisors being 1, 2, 3, 6 and 9. Three of these divisors (3, 6 and 9) add up to 18, hence 18 is a semiperfect number. Eighteen is the first inverted square-prime of the form p·q².

It is a heptagonal number, and as the sum of the first three pentagonal numbers, it is a pentagonal pyramidal number. It is also the sum of the totient function for the first seven integers. It is the sixth lucas number.
