Macfarlane Observatory
The Macfarlane Observatory was established at the University of Glasgow in 1757. It was the first purpose-built university observatory in Britain. History The Observatory was named after Alexander MacFarlane, a merchant and slave-owner in Kingston, Jamaica, who bequeathed instruments to the University on his death in 1755.DJ Bryden (1970) "The Jamaican Observatories of Colin Campbell and Alexander Macfarlane", ''Notes and Records of the Royal Society of London'' 24:261–272 Macfarlane graduated with an MA from the university in 1728. He emigrated to Jamaica in 1735. He later became assistant judge and member of the Legislative Assembly of Jamaica. Macfarlane purchased the astronomical instruments of Colin Campbell after 1742. The instruments arrived to Glasgow in a deteriorated condition, and their suitability for mounting was in question before they were taken in hand by James Watt in 1756. Watt trained in London and upon returning to Glasgow served as instrument maker to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Observatories In Scotland
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, ...

History Of Glasgow
This article deals with the history of the city of Glasgow, Scotland. See also Timeline of Glasgow history. Founding of the city The present site of Glasgow has been settled since prehistoric times, being the furthest downstream fording point of the River Clyde, at its confluence with the Molendinar Burn. The Romans built outposts in the area and constructed the Antonine Wall to keep Roman Britannia separate from Celtic and Pictish Caledonia. Items from the wall, such as altars from Roman forts, including Balmuildy, can be seen in the Hunterian Museum. After the Romans withdrew from Caledonia, the village was part of the large Kingdom of Strathclyde, whose capital was at Dumbarton downstream. It merged in the 9th century with other regions to create the united Kingdom of Scotland.The City of Glasgow – The Third Statistical Account of Scotland, published 1958 The origins of Glasgow as an established city derive from its medieval position as Scotland's second largest bisho ...

Slavery In The Caribbean
Slavery in the British and French Caribbean refers to slavery in the parts of the Caribbean dominated by France or the British Empire. History In the Caribbean, England colonised the islands of St. Kitts and Barbados in 1623 and 1627 respectively, and later, Jamaica in 1655. In these islands and England's other Caribbean colonies, white colonists would gradually introduce a system of slave-based labor to underpin a new economy based on cash crop production. French institution of slavery In the mid-16th century, enslaved people were trafficked from Africa to the Caribbean by European mercantilists. Originally, white European indentured servants worked alongside enslaved African people in the "New World" (the Americas). At this time, there were not widespread theories of race or racism that would cause different treatment for white indentured servants and enslaved African people. Francois Bernier, who is considered to have presented the first modern concept of race, publish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Observatory, Greenwich
The Royal Observatory, Greenwich (ROG; known as the Old Royal Observatory from 1957 to 1998, when the working Royal Greenwich Observatory, RGO, temporarily moved south from Greenwich to Herstmonceux) is an observatory situated on a hill in Greenwich Park in south east London, overlooking the River Thames to the north. It played a major role in the history of astronomy and navigation, and because the Prime Meridian passes through it, it gave its name to Greenwich Mean Time, the precursor to today's Coordinated Universal Time (UTC). The ROG has the IAU observatory code of 000, the first in the list. ROG, the National Maritime Museum, the Queen's House and the clipper ship ''Cutty Sark'' are collectively designated Royal Museums Greenwich. The observatory was commissioned in 1675 by King Charles II, with the foundation stone being laid on 10 August. The old hilltop site of Greenwich Castle was chosen by Sir Christopher Wren, a former Savilian Professor of Astronomy; as Greenw ...

Prime Meridian
A prime meridian is an arbitrary meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like the Earth, into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. The Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Greenwich Meridian, the previous standard. A prime meridian for a planetary body not tidally locked (or at least not in synchronous rotation) is entirely arbitrary, unlike an equator, which is determined by the axis of rotation. However, for celestial objects that are tidally locked (more specifically, synchronous), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Nautical Almanac
''The Nautical Almanac'' has been the familiar name for a series of official British almanacs published under various titles since the first issue of ''The Nautical Almanac and Astronomical Ephemeris'', for 1767: this was the first nautical almanac to contain data dedicated to the convenient determination of longitude at sea. It was originally published from the Royal Greenwich Observatory in England. 'ESAE 1961': Explanatory Supplement to the Astronomical Ephemeris and the American Ephemeris and Nautical Almanac' ('prepared jointly by the Nautical Almanac Offices of the United Kingdom and the United States of America', HMSO, London, 1961)'ESAA 1992': ed. P.K. Seidelmann, Explanatory Supplement to the Astronomical Almanac' (CA, 1992). A detailed account of how the publication was produced in its earliest years has been published by the National Maritime Museum.

Method Of Lunar Distances
In celestial navigation, lunar distance is the angular distance between the Moon and another celestial body. The lunar distances method uses this angle, also called a lunar, and a nautical almanac to calculate Greenwich time if so desired, or by extension any other time. That calculated time can be used in solving a spherical triangle. The theory was first published by Johannes Werner in 1524, before the necessary almanacs had been published. A fuller method was published in 1763 and used until about 1850 when it was superseded by the marine chronometer. A similar method uses the positions of the Galilean moons of Jupiter. Purpose In celestial navigation, knowledge of the time at Greenwich (or another known place) and the measured positions of one or more celestial objects allows the navigator to calculate latitude and longitude. Reliable marine chronometers were unavailable until the late 18th century and not affordable until the 19th century. After the method was ...

Marine Chronometer
A marine chronometer is a precision timepiece that is carried on a ship and employed in the determination of the ship's position by celestial navigation. It is used to determine longitude by comparing Greenwich Mean Time (GMT), or in the modern world its successor Coordinated Universal Time (UTC), and the time at the current location found from observations of celestial bodies. When first developed in the 18th century, it was a major technical achievement, as accurate knowledge of the time over a long sea voyage was vital for effective navigation, lacking electronic or communications aids. The first true chronometer was the life work of one man, John Harrison, spanning 31 years of persistent experimentation and testing that revolutionized naval (and later aerial) navigation and enabling the Age of Discovery and Colonialism to accelerate. The term ''chronometer'' was coined from the Greek words '' χρόνος (chronos)'' (meaning time) and ''meter'' (meaning measure) in 1713 by ...
