Field (agriculture)

In agriculture, a field is an area of land, enclosed or otherwise, used for agricultural purposes such as cultivating crops or as a paddock or other enclosure for livestock. A field may also be an area left to lie fallow or as arable land.

Many farms have a field border, usually composed of a strip of shrubs and vegetation, used to provide food and cover necessary for the survival of wildlife. It has been found that these borders may lead to an increased variety of animals and plants in the area, but also in some cases a decreased yield of crops.

Language

In Australian and New Zealand English, any agricultural field may be called a paddock. If stock are grazed there, the space may be called a run, e.g. sheep run; cattle run.

Field (computer science)

In computer science, data that has several parts, known as a record, can be divided into fields. Relational databases arrange data as sets of database records, also called rows. Each record consists of several fields; the fields of all records form the columns.

In object-oriented programming, field (also called data member or member variable) is the data encapsulated within a class or object. In the case of a regular field (also called instance variable), for each instance of the object there is an instance variable: for example, an Employee class has a Name field and there is one distinct name per employee. A static field (also called class variable) is one variable, which is shared by all instances.

Fixed length

Fields that contain a fixed number of bits are known as fixed length fields. A four byte field for example may contain a 31 bit binary integer plus a sign bit (32 bits in all). A 30 byte name field may contain a persons name typically padded with blanks at the end. The disadvantage of using fixed length fields is that some part of the field may be wasted but space is still required for the maximum length case. Also, where fields are omitted, padding for the missing fields is still required to maintain fixed start positions within a record for instance.

Field (mathematics)

In mathematics, a field is one of the fundamental algebraic structures used in abstract algebra. It is a nonzero commutative division ring, or equivalently a ring whose nonzero elements form an abelian group under multiplication. As such it is an algebraic structure with notions of addition, subtraction, multiplication, and division satisfying the appropriate abelian group equations and distributive law. The most commonly used fields are the field of real numbers, the field of complex numbers, and the field of rational numbers, but there are also finite fields, algebraic function fields, algebraic number fields, p-adic fields, and so forth.

Any field may be used as the scalars for a vector space, which is the standard general context for linear algebra. The theory of field extensions (including Galois theory) involves the roots of polynomials with coefficients in a field; among other results, this theory leads to impossibility proofs for the classical problems of angle trisection and squaring the circle with a compass and straightedge, as well as a proof of the Abel–Ruffini theorem on the algebraic insolubility of quintic equations. In modern mathematics, the theory of fields (or field theory) plays an essential role in number theory and algebraic geometry.

Cocoon (film)

Cocoon is a 1985 American science fiction fantasy comedy-drama film directed by Ron Howard about a group of elderly people rejuvenated by aliens. The movie stars Don Ameche, Wilford Brimley, Hume Cronyn, Brian Dennehy, Jack Gilford, Steve Guttenberg, Maureen Stapleton, Jessica Tandy, Gwen Verdon, Herta Ware, Tahnee Welch, and Linda Harrison. The film is loosely based on the novel of the same name by David Saperstein.

The film was shot in and around St. Petersburg, Florida: locations included the St Petersburg Shuffleboard Club, Sunny Shores Rest Home, The Coliseum, and Snell Arcade buildings. The film earned two Academy Awards for Best Supporting Actor (Don Ameche) and for Best Visual Effects.

A sequel, Cocoon: The Return, was released in 1988 in which almost all of the original cast reprised their roles.

Plot

About 10,000 years ago, peaceful aliens from the planet Antarea set up an outpost on the planet Earth, on an island later known to mankind as Atlantis. When Atlantis sank, twenty aliens were left behind, kept alive in large rock-like cocoons at the bottom of the Atlantic Ocean. Now a group of Antareans have returned to Earth to collect them. Disguising themselves as humans, they rent a house with a swimming pool, and charge the water with "life force" to give the cocooned Antareans energy to survive the trip home. They charter a boat from a local captain named Jack (Steve Guttenberg) who helps them retrieve the cocoons. Jack likes Kitty (Tahnee Welch), a beautiful woman from the team who chartered his boat. When he spies on her while she undresses in her cabin, Jack is shocked when he discovers she is an alien. After the aliens reveal themselves to him and explain what's going on, he decides to help them.

Cocoon (Pandelis Karayorgis album)

Cocoon is an album by jazz pianist Pandelis Karayorgis, which was recorded in 2012 and released on Driff, an artist-run label co-founded by Karayorgis and Jorrit Dijkstra. It was the debut recording of his trio with bassist Jef Charland and drummer Luther Gray.

Reception

The All About Jazz review by Mark Corroto states "Karayorgis' music is a blotter for the music of Herbie Nichols, Thelonious Monk, and Andrew Hill. Like these skilled innovators, the signature on these compositions (six out of ten here) is his explanation of swing. The pianist combines the playfulness of Alexander von Schlippenbach with the physicality of Don Pullen to create a slightly unbalanced sound."

The Point of Departure review by Troy Collins says "Subtly recalling past antecedents in their vanguard reinterpretations of classic piano trio tenets, Karayorgis' longstanding partnership with Charland and Gray has merited widespread critical acclaim; Cocoon is a certifiable document of their enduring, congenial rapport."
