Longwood, Saint Helena
Longwood is a settlement and a district of the British island of Saint Helena in the South Atlantic Ocean. Description In 2021, Longwood had a population of 765, compared with a population of 960 in 1998. The area of the district is . The district is second only in size to Blue Hill, and includes the settlement of Hutt's Gate, with its St Matthew's church. The district also contains the island's only golf course. The district contains Prosperous Bay Plain, which is where Saint Helena Airport and the Millennium Forest is located. There is a weather recording station in the Longwood district. Readings of temperature, air pressure and visibility are automatically taken and communicated every three hours. History Observatories On leaving the University of Oxford, in 1676, Edmond Halley visited Saint Helena and set up an observatory with a aerial telescope with the intention of studying stars from the Southern Hemisphere. The site of this telescope is near St Matthew's churc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sovereign State
A sovereign state or sovereign country, is a political entity represented by one central government that has supreme legitimate authority over territory. International law defines sovereign states as having a permanent population, defined territory (see territorial disputes), one government, and the capacity to enter into relations with other sovereign states. It is also normally understood that a sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being recognised by other sovereign states.Thomas D. Grant, ''The recognition of states: law and practice in debate and evolution'' (Westport, Connecticut: Praeger, 1999), chapter 1. Unrecognised states will often find it difficult to exercise full treaty-making powers or engage in diplomatic relations with other sovereign states. History Since the end of the 19th century, almost the entire globe has been divided into sections (countries) with more or less define ...

Sovereignty
Sovereignty is the defining authority within individual consciousness, social construct, or territory. Sovereignty entails hierarchy within the state, as well as external autonomy for states. In any state, sovereignty is assigned to the person, body, or institution that has the ultimate authority over other people in order to establish a law or change an existing law. In political theory, sovereignty is a substantive term designating supreme legitimate authority over some polity. In international law, sovereignty is the exercise of power by a state. ''De jure'' sovereignty refers to the legal right to do so; ''de facto'' sovereignty refers to the factual ability to do so. This can become an issue of special concern upon the failure of the usual expectation that ''de jure'' and ''de facto'' sovereignty exist at the place and time of concern, and reside within the same organization. Etymology The term arises from the unattested Vulgar Latin's ''*superanus'', (itself derived ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longwood House
Longwood House is a mansion in St. Helena and the final residence of Napoleon Bonaparte, the former Emperor of the French, during his exile on the island of Saint Helena, from 10 December 1815 until his death on 5 May 1821. History Longwood "was originally a farm belonging to the East India Company and was afterwards given as a country residence to the Deputy-Governor." It was converted for the use of Napoleon in 1815. The British government eventually recognized its inadequacy as a home for the former emperor and his entourage and, by the time of his death, had built a new house for him nearby, which he never occupied. In February 1818, Governor Sir Hudson Lowe proposed to Lord Bathurst to move Napoleon to Rosemary Hall, a house that became available and was located in a more hospitable part of the island, sheltered from the winds and shaded, as Napoleon had preferred. But the revelations of General Gourgaud in London brought Lord Bathurst to the opinion that it was saf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Briars, Saint Helena
Briars is the name of the small pavilion in which Napoleon Bonaparte stayed for the first few weeks of his exile on Saint Helena in late 1815 before being moved to Longwood House. The pavilion was in the garden of William Balcombe, an English merchant who became a purveyor to Napoleon. His 14-year-old daughter Elizabeth Lucia ("Betsy") Balcombe was the only family member who spoke French and she became the family translator. Because of his family's closeness to Napoleon, Balcombe attracted the suspicion of Governor Hudson Lowe, and in 1818 he was forced to leave the island and return to England. The Briars was then used as the home for the Admiral assigned to St Helena. History By coincidence, the Duke of Wellington also stayed in The Briars, in 1805, on his return from a tour of duty in India. He wrote to the admiral commanding the garrison on 3 April 1816, "You may tell Bony that I find his apartments at the Elysée-Bourbon very convenient and that I hope he likes mine at ...

Nevil Maskelyne
Nevil Maskelyne (; 6 October 1732 – 9 February 1811) was the fifth British Astronomer Royal. He held the office from 1765 to 1811. He was the first person to scientifically measure the mass of the planet Earth. He created the ''British Nautical Almanac and Astronomical Ephemeris for the Meridian of the Royal Observatory at Greenwich'' using Johann Tobias Mayer's corrections for Euler's ''Lunar Theory'' tables. Biography Maskelyne was born in London, the third son of Edmund Maskelyne of Purton in Wiltshire, and his wife, Elizabeth Booth. Maskelyne's father died when he was 12, leaving the family in reduced circumstances. Maskelyne attended Westminster School and was still a pupil there when his mother died in 1748. His interest in astronomy had begun while at Westminster School, shortly after the eclipse of 14 July 1748. Maskelyne entered St Catharine's College, Cambridge in 1749, graduating as seventh wrangler in 1754. Ordained as a minister in 1755, he became a fellow ...

Information Visualization
Information is an abstract concept that refers to that which has the power to inform. At the most fundamental level information pertains to the interpretation of that which may be sensed. Any natural process that is not completely random, and any observable pattern in any medium can be said to convey some amount of information. Whereas digital signals and other data use discrete signs to convey information, other phenomena and artifacts such as analog signals, poems, pictures, music or other sounds, and currents convey information in a more continuous form. Information is not knowledge itself, but the meaning that may be derived from a representation through interpretation. Information is often processed iteratively: Data available at one step are processed into information to be interpreted and processed at the next step. For example, in written text each symbol or letter conveys information relevant to the word it is part of, each word conveys information releva ...

Above Sea Level
Height above mean sea level is a measure of the vertical distance ( height, elevation or altitude) of a location in reference to a historic mean sea level taken as a vertical datum. In geodesy, it is formalized as '' orthometric heights''. The combination of unit of measurement and the physical quantity (height) is called " metres above mean sea level" in the metric system, while in United States customary and imperial units it would be called "feet above mean sea level". Mean sea levels are affected by climate change and other factors and change over time. For this and other reasons, recorded measurements of elevation above sea level at a reference time in history might differ from the actual elevation of a given location over sea level at a given moment. Uses Metres above sea level is the standard measurement of the elevation or altitude of: * Geographic locations such as towns, mountains and other landmarks. * The top of buildings and other structures. * Flying ob ...

Barometric Pressure
Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as , which is equivalent to 1013.25 millibars, 760 mm Hg, 29.9212 inchesHg, or 14.696 psi.International Civil Aviation Organization. ''Manual of the ICAO Standard Atmosphere'', Doc 7488-CD, Third Edition, 1993. . The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth; that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. In most circumstances, atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point. As elevation increases, there is less overlying atmospheric mass, so atmospheric pressure decreases with increasing elevation. Because the atmosphere is thin relative to the Earth's radius—especially the dense atmospheric layer at low altitudes—the Earth's ...
