Atlas

An atlas is a collection of maps; it is typically a map of Earth or a region of Earth, but there are atlases of the other planets (and their satellites) in the Solar System. Furthermore, atlases of anatomy exist, mapping out the human body or other organisms. Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it.

Etymology

The word atlas dates from 1636, first in reference to the English translation of Atlas, sive cosmographicae meditationes de fabrica mundi (1585) by Flemish geographer Gerhardus Mercator, who might have been the first to use this word in this way. A picture of the Titan Atlas holding up the world appeared on the frontispiece of this and other early map collections.

History

The first work that contained systematically arranged woodcut maps of uniform size, intended to be published in a book, thus representing the first modern atlas, was De Summa totius Orbis (1524–26) by the 16th-century Italian cartographer Pietro Coppo. Nonetheless, this distinction is conventionally awarded to the Flemish cartographer Abraham Ortelius who in 1570 published the collection of maps Theatrum Orbis Terrarum.

Atlas (computer)

The Atlas Computer was a joint development between the University of Manchester, Ferranti, and Plessey. The first Atlas, installed at Manchester University and officially commissioned in 1962, was one of the world's first supercomputers, considered to be the most powerful computer in the world at that time. It was said that whenever Atlas went offline half of the United Kingdom's computer capacity was lost. It was a second-generation machine, using discrete germanium transistors. Two other Atlas machines were built: one for British Petroleum and the University of London, and one for the Atlas Computer Laboratory at Chilton near Oxford.

A derivative system was built by Ferranti for Cambridge University. Called the Titan, or Atlas 2, it had a different memory organisation and ran a time-sharing operating system developed by Cambridge University Computer Laboratory. Two further Atlas 2s were delivered: one to the CAD Centre in Cambridge (later called CADCentre, then AVEVA), and the other to the Atomic Weapons Research Establishment (AWRE), Aldermaston.

Atlas (topology)

In mathematics, particularly topology, one describes a manifold using an atlas. An atlas consists of individual charts that, roughly speaking, describe individual regions of the manifold. If the manifold is the surface of the Earth, then an atlas has its more common meaning. In general, the notion of atlas underlies the formal definition of a manifold and related structures such as vector bundles and other fibre bundles.

Charts

The definition of an atlas depends on the notion of a chart. A chart for a topological space M (also called a coordinate chart, coordinate patch, coordinate map, or local frame) is a homeomorphism from an open subset U of M to an open subset of Euclidean space. The chart is traditionally recorded as the ordered pair .

Formal definition of atlas

An atlas for a topological space M is a collection of charts on M such that . If the codomain of each chart is the n-dimensional Euclidean space and the atlas is connected, then M is said to be an n-dimensional manifold.

Stadium

A stadium (plural stadiums or stadia) is a place or venue for (mostly) outdoor sports, concerts, or other events and consists of a field or stage either partly or completely surrounded by a tiered structure designed to allow spectators to stand or sit and view the event.

Pausanias noted that for about half a century the only event at the ancient Greek Olympic festival was the race that comprised one length of the stade at Olympia, where the word "stadium" originated.

Etymology

"Stadium" is the Latin form of the Greek word "stadion" (στάδιον), a measure of length equalling the length of 600 human feet. As feet are of variable length the exact length of a stadion depends on the exact length adopted for 1 foot at a given place and time. Although in modern terms 1 stadion = 600 ft (180 m), in a given historical context it may actually signify a length up to 15% larger or smaller.

The equivalent Roman measure, the stadium, had a similar length — about 185 m (607 ft) - but instead of being defined in feet was defined using the Roman standard passus to be a distance of 125 passūs (double-paces).

Stadium (St. Louis MetroLink)

Stadium is a St. Louis MetroLink station. This station serves Busch Stadium, home of the St. Louis Cardinals, (the previous International Bowling Museum and Hall of Fame), Westin Saint Louis Hotel and Ballpark Village in St. Louis, Missouri. It was one of six MetroLink stations in the Downtown St. Louis Ride Free Zone at lunch time on weekdays prior to the 2009 service reduction.

Stadium (UTA station)

Stadium is a light rail station on the campus of the University of Utah in Salt Lake City, Utah, United States, served by the Red Line of the Utah Transit Authority's (UTA) TRAX light rail system. The Red Line provides a service from the University of Utah Medical Center to the Daybreak Community of South Jordan.

Description

The address listed by UTA for the station is 1349 East 500 South (East University Boulevard/SR-186). However, the station's two side platforms are actually located immediately east of a one-way (southbound only) section of University Street (SR-282). The station is easily accessible from both 400 South and 500 South, but not University Street (except at the two previously indicated streets). Situated on the western edge of the University of Utah Campus, the station is just west of the University's Rice-Eccles Stadium with the stadium's parking lot in between. (Rice-Eccles Stadium was the site of the Opening and Closing Ceremonies of the 2002 Winter Olympics, as well as home of the Real Salt Lake major league soccer team [2005-2008].) The area west of the station is older residential housing; southeast of the station is the Mount Olivet Cemetery. As part of the UTA's Art in Transit program, the station features a woven bronze sculpture created by Michael Stutz entitled Flame Figure. Installed in December 2001, the sculpture was commissioned by the Salt Lake City Arts Council to commemorate the 2002 Winter Olympics. Unlike most TRAX stations, Stadium does not have a Park and Ride lot. The station is part of a railway right of way that was created specifically for the former University Line. The station was opened on 15 December 2001 as part of the former University Line and is operated by the Utah Transit Authority.
