Underwater

Underwater refers to the region below the surface of water where the water exists in a natural feature (called a body of water) such as an ocean, sea, lake, pond, or river.

Extent

Three quarters of the planet Earth is covered by water. A majority of the planet's solid surface is abyssal plain, at depths between 4,000 and 5,500 metres (13,100 and 18,000 ft) below the surface of the oceans. The solid surface location on the planet closest to the centre of the orb is the Challenger Deep, located in the Mariana Trench at a depth of 10,924 metres (35,840 ft). Although a number of human activities are conducted underwater—such as research, scuba diving for work or recreation, or even underwater warfare with submarines, this very extensive environment on planet Earth is hostile to humans in many ways and therefore little explored. But it can be explored by sonar, or more directly via manned or autonomous submersibles. The ocean floors have been surveyed via sonar to at least a coarse resolution; particularly-strategic areas have been mapped in detail, in the name of detecting enemy submarines, or aiding friendly ones, though the resulting maps may still be classified.

Underwater!

Underwater! is a 1955 adventure film directed by John Sturges and starring Jane Russell and Richard Egan.

Plot synopsis

Johnny (Richard Egan) and his wife Theresa (Jane Russell), along with mercenary Dominic Quesada (Gilbert Roland), priest Father Cannon (Robert Keith) and Gloria (Lori Nelson), the boat owner, search for sunken treasure in the Caribbean. While on a dive they come across a wreck that they assume holds treasure. When they resurface they are confronted by a local boat with an unhealthy curiosity in their activities. In their effort to find funding to raise the wreck they discover that what they are looking for is a 17th-century ship that contains a life size solid gold Madonna encrusted in precious gems and that it lies in a different underwater location. And so, they set about to acquire it. However, it's on the edge of a precipice in shark infested waters and they are not the only ones after it.

Underwater (Delerium song)

"Underwater" is a single by Canadian electronic music group Delerium, featuring Australian singer Rani Kamal (daughter of Kamahl) on vocals. It was the second single released from the album, Poem, and reached number nine on the Billboard Hot Dance Club Play chart in the U.S.

Song

The album version of the song has a slow, ambient arrangement focused primarily on strings performances. Like nearly all Delerium singles to date since "Silence", the single release put greater emphasis on a number of trance remixes commissioned by Nettwerk Music Group in order to promote the song through club play.

Notable remixers featured on the various releases of the single include Above & Beyond, Rank 1, Hydrogen Rockers (an alias of Dirty Vegas), and Peter Luts (of Ian Van Dahl and Lasgo).

The music video for the song was directed by directors collective Twobigeyes. It was aired in two different edits, which were set to the Above & Beyond remix (the more common version) and the Rank 1 remix.

Transform (EP)

Transform is the second single album by the South Korean boy band Teen Top. It was released in January 11, 2011 with the song "Supa Luv" as the title track. A remix version of the song was released in February 18, 2011.

History

The K-pop world has been buzzing over the group's hot new looks, including their eye-catching, silver-haired cyborg concept. This time Teen Top's album photography is done by renowned photographer Hong Jang Hyun, who previously worked with Big Bang, 2NE1, and Lee Hyo Ri. It also helps to have Shinhwa's Eric around to feature in the teaser for the title song Supa Luv, a stylish dance pop number produced by Shin Hyuk (the producer of Justin Bieber's One Less Lonely Girl).

Transformation (function)

In mathematics, particularly in semigroup theory, a transformation is any function f mapping a set X to itself, i.e. f:X→X. In other areas of mathematics, a transformation may simply be any function, regardless of domain and codomain. This wider sense shall not be considered in this article; refer instead to the article on function for that sense.

Examples include linear transformations and affine transformations, rotations, reflections and translations. These can be carried out in Euclidean space, particularly in dimensions 2 and 3. They are also operations that can be performed using linear algebra, and described explicitly using matrices.

Translation

A translation, or translation operator, is an affine transformation of Euclidean space which moves every point by a fixed distance in the same direction. It can also be interpreted as the addition of a constant vector to every point, or as shifting the origin of the coordinate system. In other words, if v is a fixed vector, then the translation T_v will work as T_v(p) = p + v.
