Antipodal Point
In mathematics, antipodal points of a sphere are those diametrically opposite to each other (the specific qualities of such a definition are that a line drawn from the one to the other passes through the center of the sphere so forms a true diameter). This term applies to opposite points on a circle or any n-sphere. An antipodal point is sometimes called an antipode, a back-formation from the Greek loan word ''antipodes'', meaning "opposite (the) feet", as the true word singular is ''antipus''. Theory In mathematics, the concept of ''antipodal points'' is generalized to spheres of any dimension: two points on the sphere are antipodal if they are opposite ''through the centre''; for example, taking the centre as origin, they are points with related vectors v and −v. On a circle, such points are also called diametrically opposite. In other words, each line through the centre intersects the sphere in two points, one for each ray out from the centre, and these two poin ...

Antipodes
In geography, the antipode () of any spot on Earth is the point on Earth's surface diametrically opposite to it. A pair of points ''antipodal'' () to each other are situated such that a straight line connecting the two would pass through Earth's center. Antipodal points are as far away from each other as possible. The North and South Poles are antipodes of each other. In the Northern Hemisphere, "the Antipodes" may refer to Australia and New Zealand, and Antipodeans to their inhabitants. Geographically, the antipodes of Britain and Ireland are in the Pacific Ocean, south of New Zealand. This gave rise to the name of the Antipodes Islands of New Zealand, which are close to the antipode of London. With the exception of a part of the Perth metropolitan area near Baldivis and Rockingham that is antipodal to Bermuda, the antipodes of Australia are in the North Atlantic Ocean, while parts of Spain, Portugal, France and Morocco are antipodal to New Zealand. Approximately 15% of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipodes Islands
The Antipodes Islands ( Maōri: Moutere Mahue; "Abandoned island") are inhospitable and uninhabited volcanic islands in subantarctic waters to the south of – and territorially part of – New Zealand. The 21 km2 archipelago lies 860 km to the southeast of Stewart Island/Rakiura, and 730 km to the northeast of Campbell Island. They are very close to being the antipodal point to Normandy in France, meaning that the city farthest away is Cherbourg-en-Cotentin, France. The island group consists of one main island, Antipodes Island, of 20 km2 area, Bollons Island to the north, and numerous small islets and stacks. The islands are listed with the New Zealand Outlying Islands. The islands are an immediate part of New Zealand, but not part of any region or district, but instead ''Area Outside Territorial Authority'', like all the other outlying islands except the Solander Islands. Ecologically, the islands are part of the Antipodes Subantarctic Islands tundr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasia
Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colonies) and New Zealand. Australasia found continued geopolitical attention in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antipodes (sculpture)
''Antipodes'' is a public artwork by American sculptor Jim Sanborn located outside of the Hirshhorn Museum and Sculpture Garden in Washington, DC, United States. Description This sculpture consists of two copper curved pieces attached to a piece of petrified wood by steel bands. The "scrolls" have letters punched into them, one piece is in English and the other piece is "coded" in Cyrillic. Acquisition The original ''Antipodes'' is a 6-foot high version of the Hirshhorn sculpture that was created in 1992 which was purchased by art collectors Gilbert and Ann Kinney. The small piece was displayed on the terrace of the Kinney home and upon moving the couple donated the piece to the Hirshhorn. In 1997 the Neuberger Museum of Art commissioned a large scale version of ''Antipodes'' for the Neuberger Biennial. After the Biennial, Sanborn traded the large piece for the smaller version to the Hirshhorn, hence it now residing outside the Washington-based museum. The smaller version of '' ...

The Antipodes
''The Antipodes'' is a Caroline era stage play, a comedy written by Richard Brome c. 1636. Many critics have ranked ''The Antipodes'' as "his best play...Brome's masterpiece," and one of the best Caroline comedies – "gay, imaginative, and spirited...;" "the most sophisticated and ingenious of Brome's satires." Brome's play is "a funhouse mirror" in which the audience members could "view the nature of their society." Date, performance, and publication ''The Antipodes'' was entered into the Stationers' Register on 19 March 1640 and published later that year in a quarto printed by John Okes, the son and successor of printer Nicholas Okes, for the bookseller Francis Constable. The title page states that the play was acted in 1638 by Queen Henrietta's Men at the Salisbury Court Theatre, the regular troupe and venue for Brome's dramas from 1637 on. In a note addressed to the Courteous Reader at the end of the printed text, however, Brome writes that the play was originally intende ...

Abarimon
Abarimon or antipode in mythology are people whose feet are turned backwards, but in spite of this handicap were able to run at great speed. In Europe, this tribe was first described by Pliny the Elder, in his book, ''Natural History'' (VII 11), who considered them to be native to India. A similar tale is recounted by Aulus Gellius in ''Attic Nights''. They lived side by side with wild animals and attempts to capture them failed because they were so savage. Pliny refers to information that originates from Baiton, which was Alexander the Great's Land Surveyor. Baiton says that the ''abarimons'' could only breathe the air in their own domestic valleys. Because of the special quality of air, which meant if it was breathed for a long period of time, it would be impossible to breathe any other type of air. Therefore the inhabitants were unable to leave the valley and live anywhere else. And so it was impossible to capture them and bring them to the courts of a distant ruler, or to the ...

Antipodes (submersible)
''Antipodes'' is a 5-person crewed submersible. ''Antipodes'' is certified by the American Bureau of Shipping (ABS) and has completed more than 1,300 dives in a variety of sea conditions. History Origins ''Antipodes'' started as the ''PC-1501'' submersible originally built in 1973 by the Perry Submarine Company as a diver lock-out vehicle, similar in concept to ''Deep Diver'' (1966). It spent several years operating in the North Sea oil fields as a ferry for commercial divers. In 1988, Hoffmann Yacht Sales purchased ''PC-1501'' and hired Marlin Submarines in 1994 to manage the conversion of the craft. The pilot compartment from ''PC-1501'' was reused and modified by installing domed, windows encompassing a 150° arc and window seat forgings at each end of the hull. The conning tower was fitted with seven windows with a conical frustum cross-section. The modified hull and battery pods were pressure tested to and certified to American Bureau of Shipping (ABS) standards; ABS sur ...
