Europa (mythology)

In Greek mythology Europa (/jʊˈroʊpə, jə-/; Greek: Εὐρώπη Eurṓpē) was the mother of King Minos of Crete, a woman with Phoenician origin of high lineage, and for whom the continent Europe was named. The story of her abduction by Zeus in the form of a white bull was a Cretan story; as Kerényi points out "most of the love-stories concerning Zeus originated from more ancient tales describing his marriages with goddesses. This can especially be said of the story of Europa".

Europa's earliest literary reference is in the Iliad, which is commonly dated to the 8th century B.C. Another early reference to her is in a fragment of the Hesiodic Catalogue of Women, discovered at Oxyrhynchus. The earliest vase-painting securely identifiable as Europa, dates from mid-7th century B.C.

Etymology

The etymology of her Greek name (εὐρύς eurys "wide" or "broad" and ὤψ ops "eye(s)" or "face") suggests that Europa as a divine spirit represented the wide-faced cow Hathor, at least on some symbolic level. Metaphorically, at a later date her name could be construed as the intelligent or open-minded, analogous to glaukopis (γλαυκῶπις) attributed to Athena. However, Ernest Klein and Giovanni Semerano suggest a possible Semitic origin in Akkadian erebu "to go down, set" (in reference to the sun) which would parallel occident.

Class (knowledge representation)

In knowledge representation, a class is a collection of individuals or objects. A class can be defined either by extension, or by intension, using what is called in some ontology languages like OWL. If we follow the Type–token distinction, the ontology is divided into individuals, who are real worlds objects, or events, and types, or classes, who are sets of real world objects. Class expressions or definitions gives the properties that the individuals must fulfill to be members of the class. Individuals that fulfill the property are called Instances.

Relationships

Instantiation

The instantiation relationship is a relation between objects and classes. We say that an object O, say Harry the eagle is an instance of a class, say Eagle. Harry the eagle has all the properties that we can attribute to an eagle, for example his parents were eagles, he's a bird, he's a meat eater and so on. It's a special kind of is a relationship. It's noted Concept assertion () in Description logics, a family of logic based on classes, class assertion

Doctor Who

Doctor Who is a British science-fiction television programme produced by the BBC from 1963 to the present day. The programme depicts the adventures of the Doctor, a Time Lord—a space and time-travelling humanoid alien. He explores the universe in his TARDIS, a sentient time-travelling space ship. Its exterior appears as a blue British police box, which was a common sight in Britain in 1963 when the series first aired. Accompanied by companions, the Doctor combats a variety of foes, while working to save civilisations and help people in need.

The show is a significant part of British popular culture, and elsewhere it has become a cult television favourite. The show has influenced generations of British television professionals, many of whom grew up watching the series. The programme originally ran from 1963 to 1989. There was an unsuccessful attempt to revive regular production in 1996 with a backdoor pilot, in the form of a television film. The programme was relaunched in 2005 by Russell T Davies, who was showrunner and head writer for the first five years of its revival, produced in-house by BBC Wales in Cardiff. The first series of the 21st century featured Christopher Eccleston in the title role and was produced by the BBC. Series two and three had some development money contributed by the Canadian Broadcasting Corporation (CBC), which was credited as a co-producer.Doctor Who also spawned spin-offs in multiple media, including Torchwood (2006–2011) and The Sarah Jane Adventures (2007–2011), both created by Russell T Davies; K-9 (2009–2010); and a single pilot episode of K-9 and Company (1981). There also have been many spoofs and cultural references to the character in other media.

Class (set theory)

In set theory and its applications throughout mathematics, a class is a collection of sets (or sometimes other mathematical objects) that can be unambiguously defined by a property that all its members share. The precise definition of "class" depends on foundational context. In work on Zermelo–Fraenkel set theory, the notion of class is informal, whereas other set theories, such as Von Neumann–Bernays–Gödel set theory, axiomatize the notion of "proper class", e.g., as entities that are not members of another entity.

A class that is not a set (informally in Zermelo–Fraenkel) is called a proper class, and a class that is a set is sometimes called a small class. For instance, the class of all ordinal numbers, and the class of all sets, are proper classes in many formal systems.

Outside set theory, the word "class" is sometimes used synonymously with "set". This usage dates from a historical period where classes and sets were not distinguished as they are in modern set-theoretic terminology. Many discussions of "classes" in the 19th century and earlier are really referring to sets, or perhaps to a more ambiguous concept.
