Latitude

In geography, latitude (φ) is a geographic coordinate that specifies the north-south position of a point on the Earth's surface. Latitude is an angle (defined below) which ranges from 0° at the Equator to 90° (North or South) at the poles. Lines of constant latitude, or parallels, run east-west as circles parallel to the equator. Latitude is used together with longitude to specify the precise location of features on the surface of the Earth. Two levels of abstraction are employed in the definition of these coordinates. In the first step the physical surface is modelled by the geoid, a surface which approximates the mean sea level over the oceans and its continuation under the land masses. The second step is to approximate the geoid by a mathematically simpler reference surface. The simplest choice for the reference surface is a sphere, but the geoid is more accurately modelled by an ellipsoid. The definitions of latitude and longitude on such reference surfaces are detailed in the following sections. Lines of constant latitude and longitude together constitute a graticule on the reference surface. The latitude of a point on the actual surface is that of the corresponding point on the reference surface, the correspondence being along the normal to the reference surface which passes through the point on the physical surface. Latitude and longitude together with some specification of height constitute a geographic coordinate system as defined in the specification of the ISO 19111 standard.

Latitude (building)

Latitude is part of the World Square complex bounded by George, Goulburn, Liverpool and Pitt Street in Sydney, Australia. The building's official name is Ernst & Young Tower at Latitude and is located on the corner of George and Goulburn streets.

Design and construction

The building comprises a low rise office, a retail complex incorporating a series of laneways and a high rise commercial tower for Ernst & Young. The 51 storey structure is 190 m in height and 222 m to the top of the spire. The 51st floor is the HQ for the Australian Health practitioners regulation agency (AHPRA). The building also comprises the headquarters for Austereo and Hoyts.

The building was opened in January 2005. It was built by Multiplex.

The architect responsible for the design was Greg Crone, known for his work with King Street Wharf, Citigroup Centre and 400 George Street.

Parallel 36°30′ north

The parallel 36°30′ north is a circle of latitude that is 36 and one-half degrees north of the equator of the Earth. This parallel of latitude is particularly significant in the history of the United States as the line of the Missouri Compromise, which was used to divide the prospective slave and free states west of the Mississippi River, with the exception of Missouri, which is mostly north of this parallel.

In the United States

In the United States, the parallel 36°30′ forms part of the boundary between Tennessee and Kentucky, in the region west of the Tennessee River and east of the Mississippi River. This parallel also forms part of the boundary between Missouri and Arkansas in the region west of the St. Francis River, and part of the boundary between the Oklahoma Panhandle and the Texas Panhandle. The rest of the boundaries between Virginia and North Carolina; between Virginia and Tennessee; and between Tennessee and Kentucky lie close to the parallel 36°30′. The boundary between Kentucky and Tennessee was defined as 36°30′, based on the Royal Colonial Boundary of 1665 that set the boundary of the Colony of Virginia and the Province of Carolina.

Trident

A trident /ˈtraɪdənt/ is a three-pronged spear. It is used for spear fishing and historically as a polearm. The trident is the weapon of Poseidon, or Neptune, the god of the sea in classical mythology. In Hindu mythology it is the weapon of Shiva, known as trishula (Sanskrit for "triple-spear").

Etymology

The word "trident" comes from the French word trident, which in turn comes from the Latin word tridens or tridentis: tri "three" and dentes "teeth". Sanskrit trishula is compound of tri त्रि "three""thorn".

The Greek equivalent is τρίαινα (tríaina), from Proto-Greek trianja (threefold).

Uses

In Greek, Roman, and Hindu mythology, the trident is said to have the power of control over the ocean.

Fishing

Tridents for fishing usually have barbed tines which trap the speared fish firmly. In the Southern and Midwestern United States, gigging is used for harvesting suckers, bullfrogs, flounder, and many species of rough fish.

Combat

The trident, known as dangpa, is featured as a weapon in the 17th- to 18th-century systems of Korean martial arts.

Critical reception

The Allmusic review by Scott Yanow states "Pianist McCoy Tyner's first full-length trio album since 1964 was one of his most popular... this set finds Tyner in peak form".
