Rock (geology)

In geology, rock or stone is a naturally occurring solid aggregate of one or more minerals or mineraloids. For example, the common rock granite is a combination of the quartz, feldspar and biotite minerals. The Earth's outer solid layer, the lithosphere, is made of rock.

Rocks have been used by mankind throughout history. From the Stone Age, rocks have been used for tools. The minerals and metals found in rocks have been essential to human civilization.

Three major groups of rocks are defined: igneous, sedimentary, and metamorphic. The scientific study of rocks is called petrology, which is an essential component of geology.

Classification

At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner. The aggregate minerals forming the rock are held together by chemical bonds. The types and abundance of minerals in a rock are determined by the manner in which the rock was formed. Many rocks contain silica (SiO₂); a compound of silicon and oxygen that forms 74.3% of the Earth's crust. This material forms crystals with other compounds in the rock. The proportion of silica in rocks and minerals is a major factor in determining their name and properties.

Jet (song)

"Jet" is a song by Paul McCartney and Wings from their album Band on the Run. Supposedly written about a puppy that McCartney owned, the song was the first British and American single to be released from the album. The song peaked at number 7 in both the British and American charts on 30 March 1974, also charting in multiple countries in Europe. It has been released on numerous compilation albums, and has since become one of the band's most well-known tracks.

Along with "Helen Wheels" and "Junior's Farm", "Jet" is another McCartney song where his primary inspiration for composing the song arose in daily life.

Background

Reviewers have reported that the subject of the song is McCartney's Labrador Retriever dog named "Jet". McCartney has also substantiated this claim.

However, in a 2010 interview on the UK television channel ITV1 for the program Wings: Band on the Run (to promote the November 2010 CD/DVD re-release of the album) McCartney explained that Jet was the name of a pony he had owned, although many of the lyrics bore little relation to the subject; indeed, the true meaning of the lyrics has defied all attempts at decryption.

Jet (video game)

Jet is a combat flight simulator video game originally published in 1985 by subLOGIC.

Description

Jet is based on subLOGIC's classic Flight Simulator. The player may choose either an F-16 Fighting Falcon for land missions or an F-18 Hornet for missions starting at sea from an aircraft carrier. The player can also practice flying and aerobatics in "free flight" mode, dogfight against Soviet MiGs, launch strikes against land or sea based targets, watch a demo, or load a subLOGIC scenery disk. For either combat mode, the player can to select which missiles and bombs the plane will have.

Most of the indicators on a real jet fighter are present in Jet: altimeter, heading, frame loading, gear status, brake status, fuel level, radar, attitude, and range. The player can turn a few of these on and off. The controls consist of either the joystick or numeric keypad for steering and other keys to handle the chosen optional indicators, landing gear, weapons, and an eject button. Different perspectives can be chosen - a view from the control tower instead of the jet's cockpit.
