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.

Rocks (Aerosmith album)

Rocks is the fourth studio album by American rock band Aerosmith, released on May 3, 1976. AllMusic described Rocks as having "captured Aerosmith at their most raw and rocking".Rocks was ranked #176 on Rolling Stone's list of the 500 Greatest Albums of All Time. It has greatly influenced many hard rock and heavy metal artists, including Guns N' Roses and Metallica. The album was a commercial success, charting three singles on the Billboard Hot 100, two of which reached the Top 40 ("Back in the Saddle" and "Last Child"). The album was one of the first albums to ship platinum when it was released. The album has since gone quadruple platinum.

Background

By 1976, Aerosmith had recorded three albums: Aerosmith (1973), Get Your Wings (1974), and the breakthrough LP Toys in the Attic (1975), which produced the Top Ten hit "Walk This Way" and the popular "Sweet Emotion." Although often derided by critics, the band had amassed a loyal fan following from relentless touring and their ferocious live shows. They also began living the rock and roll lifestyle to the hilt, indulging their already considerable appetite for drugs. However, their hedonistic lifestyle did not appear to hamper them creatively; Rocks is considered by many fans, critics, and fellow musicians to be one of the highlights of their career. Guitarist Joe Perry later recalled, "There's no doubt we were doing a lot of drugs by then, but whatever we were doing, it was still working for us."

Die (integrated circuit)

A die in the context of integrated circuits is a small block of semiconducting material, on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of electronic-grade silicon (EGS) or other semiconductor (such as GaAs) through processes such as photolithography. The wafer is cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms: dice, dies, and die.

Die (manufacturing)

A die is a specialized tool used in manufacturing industries to cut or shape material mostly using a press. Like molds, dies are generally customized to the item they are used to create. Products made with dies range from simple paper clips to complex pieces used in advanced technology.

Die forming

Forming dies are typically made by tool and die makers and put into production after mounting into a press. The die is a metal block that is used for forming materials like sheet metal and plastic. For the vacuum forming of plastic sheet only a single form is used, typically to form transparent plastic containers (called blister packs) for merchandise. Vacuum forming is considered a simple molding thermoforming process but uses the same principles as die forming. For the forming of sheet metal, such as automobile body parts, two parts may be used: one, called the punch, performs the stretching, bending, and/or blanking operation, while another part, called the die block, securely clamps the workpiece and provides similar stretching, bending, and/or blanking operation. The workpiece may pass through several stages using different tools or operations to obtain the final form. In the case of an automotive component there will usually be a shearing operation after the main forming is done and then additional crimping or rolling operations to ensure that all sharp edges are hidden and to add rigidity to the panel.

Cast

Win (band)

Win were a Scottish pop band from the 1980s.

After the dissolution of The Fire Engines, Davy Henderson formed Win with Ian Stoddart (Bass), ex-Fire Engine Russell Burn (Drums/Keyboards), Emmanuel "Mani" Shoniwa (Guitar/Bass), Simon Smeeton (Guitar/Bass) and Willie Perry (Keyboards) in 1983. A more determinedly pop act than The Fire Engines, they were commercially successful in Scotland, partly due to their single "You've Got the Power" being used in a lager advertising campaign for Scottish brewers McEwan's. But they were unable to translate that into more widespread success and break through further afield. They released two albums and disbanded in 1990. Henderson went to working with his new band The Nectarine No. 9, releasing records on the revived Postcard label, Creeping Bent and Beggars' Banquet, later worked with The Sexual Objects. Willie Perry and Ian Stoddart went on to form The Apples with Callum McNair. Mani Shoniwa formed Yoyo Honey, releasing the album Voodoo Soul in 1992.
