In functional analysis, a discipline within mathematics, a core may be:

Lithic core

In archaeology, a lithic core is a distinctive artifact that results from the practice of lithic reduction. In this sense, a core is the scarred nucleus resulting from the detachment of one or more flakes from a lump of source material or tool stone, usually by using a hard hammer percussor such as a hammerstone. The core is marked with the negative scars of these flakes. The surface area of the core which received the blows necessary for detaching the flakes is referred to as the striking platform. The core may be discarded or shaped further into a core tool, such as can be seen in some types of handaxe.

The purpose of lithic reduction may be to rough out a blank for later refinement into a projectile point, knife, or other stone tool, or it may be performed in order to obtain sharp flakes, from which a variety of simple tools can be made. Generally, the presence of a core is indicative of the latter process, since the former process usually leaves no core. Because the morphology of cores will influence the shape of flakes, by studying the core surface morphology, we might be able to know more information about the dimensional flake attribute, including their length and thickness. Cores may be subdivided into specific types by a lithic analyst. Type frequencies, as well as the general types of materials at an archaeological site, can give the lithic analyst a better understanding of the lithic reduction processes occurring at that site.

Ice

Ice is water frozen into a solid state. Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color.

In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far as the Oort cloud. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surface – particularly in the polar regions and above the snow line – and, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes.

Ice molecules can exhibit up to sixteen different phases (packing geometries) that depend on temperature and pressure. When water is cooled rapidly (quenching), up to three different types of amorphous ice can form depending on the history of its pressure and temperature. When cooled slowly correlated proton tunneling occurs below 20 K giving rise to macroscopic quantum phenomena. Virtually all the ice on Earth's surface and in its atmosphere is of a hexagonal crystalline structure denoted as ice Ih (spoken as "ice one h") with minute traces of cubic ice denoted as ice Ic. The most common phase transition to ice Ih occurs when liquid water is cooled below 0°C (273.15K, 32°F) at standard atmospheric pressure. It may also be deposited directly by water vapor, as happens in the formation of frost. The transition from ice to water is melting and from ice directly to water vapor is sublimation.

Ice (1998 film)

Ice is a 1998 television disaster film starring Grant Show, Udo Kier, and Eva La Rue. The film has a similar premise as The Day After Tomorrow, a science fiction disaster film released six years later. Though completely in English, it first premiered in Germany in 1998 before being aired on ABC in the United States in 2000.

Plot

A small meteor hits the sun, causing disastrous consequences for the Earth. Los Angeles is, just as the rest of the world, covered with a layer of ice and snow. The government has collapsed and everyone is on their own. Chaos and crime prevails. Together with scientist Dr. Kistler and a small group of survivors, L.A. cop Robert Drake leaves in the direction of Long Beach Harbor to meet with a government ship which will take them to Guam, where it is warmer.

Cast

Ice (band)

Ice is an industrial music band formed by guitarist Justin Broadrick and saxophonist/vocalist Kevin Martin.

History

Keeping to a similar vein as their other musical project Techno Animal, Justin Broadrick and Kevin Martin opted for Ice to be a studio-based project. Drummer John Jobaggy and bassist Dave Cochrane were recruited to aid them in the recording process. Their debut album, Under the Skin, is comparable to Pure-era Godflesh and Martin's free jazz and dub work with God. The group went on hiatus for several years and Jobaggy was replaced by Laika drummer Lou Ciccotelli. By their second album, Bad Blood, the band had absorbed hip hop influences and nearly all the songs featured contributions from recognizable names in the underground rap scene. Blixa Bargeld, of Einsturzende Neubauten, also contributed his vocals to the music.
