Arena (short story)

"Arena" is a science fiction short story by Fredric Brown that was first published in the June 1944 issue of Astounding magazine. Members of the Science Fiction Writers of America selected it as one of the best science fiction stories published before the advent of the Nebula Awards, and as such it was included in The Science Fiction Hall of Fame Volume One, 1929-1964.

The Star Trek episode "Arena" had some similarity to this story, so to avoid legal problems, it was agreed that Brown would receive payment and a story credit. An Outer Limits episode, "Fun and Games", also has a similar plot, as does an episode of Blake's 7, titled "Duel".

Marvel Comics' Worlds Unknown issue 4 (November 1973) featured a faithful adaptation of the story.

Plot summary

The mysterious Outsiders have skirmished with Earth's space colonies and starships. Their vessels are found to be faster and more maneuverable, but less well armed. There have been no survivors of the small raids on Earth forces so Earth has no information about the Outsiders. Fearing the worst, Earth builds a war fleet. Scouts report a large armada approaching the solar system. Earth's defenders go to meet them. All indications are that the two fleets are evenly matched.

Pula Arena

The Pula Arena is the name of the amphitheatre located in Pula, Croatia. The Arena is the only remaining Roman amphitheatre to have four side towers and with all three Roman architectural orders entirely preserved. It was constructed in 27 BC – 68 AD and is among the six largest surviving Roman arenas in the World. A rare example among the 200 Roman surviving amphitheatres, it is also the best preserved ancient monument in Croatia.

The amphitheatre is depicted on the reverse of the Croatian 10 kuna banknote, issued in 1993, 1995, 2001 and 2004.

Construction

The exterior wall is constructed in limestone. The part facing the sea consists of three stories, while the other part has only two stories since the amphitheatre was built on a slope. The maximum height of the exterior wall is 29.40 m (96.5 ft). The first two floors have each 72 arches, while the top floor consists of 64 rectangular openings.

The axes of the elliptical amphitheatre are 132.45 and 105.10 m (434.5 and 344.8 ft) long, and the walls stand 32.45 m (106.5 ft) high. It could accommodate 23,000 spectators in the cavea, which had forty steps divided into two meniani. The seats rest directly on the sloping ground; The field for the games, the proper arena, measured 67.95 by 41.65 m (222.9 by 136.6 ft). The field was separated from the public by iron gates.

Arena (Australian publishing co-operative)

Arena is an independent Australian radical and critical publishing group. It has been publishing continuously since 1963. Currently, its principal publications are the political and cultural Arena Magazine (6 times per year), and the twice-yearly theoretical publication Arena Journal. Their concerns initially found expression in the practical and theoretical quarterly, Arena, which ran from 1963 to 1992 and was then transformed into the two different publications that continue today.

Though the quarterly Arena commenced as a New Left magazine with a commitment to extending Marxist approaches by developing an account of intellectual practices, its subsequent debates and theoretical work, and engagements with critical theory, media theory, post-structuralism and postmodernism, have led it to develop an approach known as the 'constitutive abstraction' approach. This is connected to an associated lineage of engaged theory. All of these are underpinned by a preoccupation with the questions of social abstraction, including the abstraction of intellectual practices. They include a special emphasis on the cultural and social contradictions of globalised hi-tech society, which the Arena editors took to be misrepresented within prevailing media theory and post-structuralism.

Poleá

The "pulley" (in Spanish: poleá) is a typical recipe of Andalusian cuisine, particularly Seville, Huelva and Cadiz. It is a variant of porridge typical of those used to consume in poor years (It was a common dish during the Spanish Civil War).

The dish is made with water, flour, salt, anise, milk and sugar. Other ingredients (such as fruit, honey or cinnamon) are sometimes added. It is usually served with fried bread.

Terminal (electronics)

A terminal is the point at which a conductor from an electrical component, device or network comes to an end and provides a point of connection to external circuits. A terminal may simply be the end of a wire or it may be fitted with a connector or fastener. In network analysis, terminal means a point at which connections can be made to a network in theory and does not necessarily refer to any real physical object. In this context, especially in older documents, it is sometimes called a pole.

The connection may be temporary, as seen in portable equipment, may require a tool for assembly and removal, or may be a permanent electrical joint between two wires or devices.

All electric cells have two terminals. The first is the positive terminal and the second is the negative terminal. The positive terminal looks like a metal cap and the negative terminal looks like a metal disc. The current flows from the positive terminal, and out through the negative terminal, replicative of current flow (positive (+) to negative (-) flow).

Pole and polar

In geometry, the pole and polar are respectively a point and a line that have a unique reciprocal relationship with respect to a given conic section. If the point lies on the conic section, its polar is the tangent line to the conic section at that point.

For a given circle, reciprocation in a circle means the transformation of each point in the plane into its polar line and each line in the plane into its pole.

Properties

Poles and polars have several useful properties:
