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.

Stone (1751 Kent cricketer)

Stone (first name and dates unknown) was an English cricketer who played in major cricket matches for Kent in 1751.

Career

Stone played in two major matches in 1751 for Kent against the All-England Eleven. On 20 and 21 May, he was a member of the Kent team that lost by 9 runs at the Artillery Ground. A return match was arranged at the same venue on 22 May and All-England won by an innings and 9 runs, with Stone again a member of the Kent team.

Stone was also named in two single wicket "fives" matches that were held on 3 and 5 June at the Artillery Ground. In both games, he played for Kent against Surrey, Kent winning each time.

Stone is only recorded on those four occasions and it is not known if he played regularly in earlier and later seasons. Players were rarely mentioned by name in contemporary reports and there are no other known references to Stone.

Wire

A wire is a single, usually cylindrical, flexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term wire is also used more loosely to refer to a bundle of such strands, as in 'multistranded wire', which is more correctly termed a wire rope in mechanics, or a cable in electricity.

Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can be made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers. Edge-woundcoil springs, such as the Slinky toy, are made of special flattened wire.

History

In antiquity, jewelry often contains, in the form of chains and applied decoration, large amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means. In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes. This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BC most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method. The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. There is some evidence for the use of drawing further East prior to this period.

Wire (Third Day album)

Wire is the seventh album by Christian rock band Third Day. It breaks from the style of the band's previous albums to return to simple, rock and roll-driven melodies. To quote Allmusic's review of the album, "Third Day has stripped away the shine and gotten back to the grittiness of being a rock & roll band." The album is largely carried by the energetic guitar riffs that pervade its songs, although the forceful lyrics also contribute significantly.

The album's songs deal with numerous themes. "Wire", the title track, is a song about the pressure to succeed in modern society. "I Believe", "I Got a Feeling", "Innocent", and other tracks deal with sin, faith, and renewal from a Christian perspective. "Billy Brown" is a catchy song that explores the readiness of people to follow and even idolize entertainment figures.

In November 2004, a live version of Wire was released, called Live Wire featuring a DVD and CD of songs from their tour of their latest album.

The album won 2005 Grammy Award for Best Rock Gospel Album.
