Elevation (song)

"Elevation" is the third track and third single release from U2's 2000 album, All That You Can't Leave Behind. It was also the band's second number one single in the Netherlands, and in 2002, "Elevation" won "Grammy Award for Best Rock Performance by a Duo or Group with Vocal." The song lent its namesake to the band's Elevation Tour.

Writing and composition

Adam came into his own on "Elevation" because he is the hip-hop man in the band and there is a real hip-hop attitude in the rhythm section.

"Elevation" started with a guitar sound that the Edge got with a vintage pedal that Daniel Lanois had brought to the sessions. Afterwards, the Edge hit on a guitar part and programmed a quick beat box rhythm and the band started playing against it, and Bono improvized. The song has a hip-hop rhythm. The Edge stated that "Elevation" was a light relief in a heavy sequence of songs, unlike "Stuck in a Moment You Can't Get Out Of", "Kite" and "Walk On" that "are farewell songs of one kind of another."

Song

A song is a single (and often standalone) work of music intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert performances. Songs are performed live and recorded. Songs may also appear in plays, musical theatre, stage shows of any form, and within operas.

Song (airline)

Song, LLC was a low-cost air service within an airline brand owned and operated by Delta Air Lines from 2003 to 2006.

Song's main focus was on leisure traffic between the northeastern United States and Florida, a market where it competed with JetBlue Airways. It also operated flights between Florida and the West Coast, and from the Northeast to the west coast.

Song's aircraft were fitted with leather seats and free personal entertainment systems at every seat, with audio MP3 programmable selections, trivia games that could be played against other passengers, a flight tracker, and satellite television (provided by the DISH Network). Song offered free beverages, but charged for meals and liquor. Both brand-name snack boxes and healthy organic meals were offered. The flight safety instructions were sung or otherwise artistically interpreted, depending on the cabin crew. In addition to crew uniforms designed by Kate Spade, customized cocktails created by nightlife impresario Rande Gerber and an in-flight exercise program designed by New York City fitness guru David Barton, the airline created its own distinct mark in the industry. The Song brand was placed on more than 200 flights a day which carried over ten million passengers.

Elevation

The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic system, vertical datum). Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface.

Less commonly, elevation is measured using the center of the Earth as the reference point. Due to equatorial bulge, there is debate as to which of the summits of Mt. Everest or Chimborazo is at the higher elevation, as the Chimborazo summit is further from the Earth's center, while the Mt. Everest summit is higher above mean sea level.

Maps and GIS

A topographical map is the main type of map used to depict elevation, often through use of contour lines. In a Geographic Information System (GIS), digital elevation models (DEM) are commonly used to represent the surface (topography) of a place, through a raster (grid) dataset of elevations. Digital terrain models are another way to represent terrain in GIS.

Anatomical terms of motion

Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used describes this motion according to its direction relative to the anatomical position of the joints. Anatomists use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing the uniqueness of the movements such as those of the hands, feet, and eyes.

In general, motion is classified according to the anatomical plane it occurs in. Flexion and extension are examples of angular motions, in which two axes of a joint are brought closer together or moved further apart. Rotational motion may occur at other joints, for example the shoulder, and are described as internal or external. Other terms, such as elevation and depression, refer to movement above or below the horizontal plane. Many anatomical terms derive from Latin terms with the same meaning.

Elevation (ballistics)

In ballistics, the elevation is the angle between the horizontal plane and the direction of the barrel of a gun, mortar or heavy artillery. Originally, elevation was a linear measure of how high the gunners had to physically lift the muzzle of a gun up from the gun carriage to hit targets at a certain distance.

Pre-WWI and WWI

Though early 20th-century firearms were relatively easy to fire, artillery was not. Before and during World War I, the only way to effectively fire artillery was plotting points on a plane.

Most artillery units seldom employed their cannons in small numbers. Instead of using pin-point artillery firing they used old means of "fire for effect" using artillery en masse. This tactic was employed successfully by past armies.

But changes have been made since past wars and in World War I, artillery was more accurate than before, although not as accurate as modern artillery guns. The tactics of artillery from previous wars were carried on, and still had similar success. Warships and battleships also carried large caliber guns that needed to be elevated to certain degrees to accurately hit targets, and they also had the similar drawbacks of land artillery.
