John Jackson (astronomer)
John Jackson (11 February 1887 – 9 December 1958) was a Scottish people, Scottish astronomer. He was awarded The Gold Medal of the Royal Astronomical Society for his work on stellar parallaxes and star positions. Early life and education Born on 11 February 1887 at Mossvale Street, Paisley, Renfrewshire, Scotland, John Jackson was educated at Paisley Grammar School, studying a range of subjects including the sciences and French and German, but not Latin or Greek, which were compulsory if he intended to sit the entrance examinations for university. Having excelled at science, in particular chemistry, he decided to try for the entrance exam for Glasgow University in spite of not studying the classics. During the summer of 1903 he studied hard to improve his knowledge of Latin, which saw him pass the university entrance exam sufficiently well to be awarded a £25 bursary. Graduating in 1907 with a first class honours Master of Arts degree in mathematics and natural philosophy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Fourth Army
The Fourth Army was a field army that formed part of the British Expeditionary Force during the First World War. The Fourth Army was formed on 5 February 1916 under the command of General Sir Henry Rawlinson to carry out the main British contribution to the Battle of the Somme. First World War History The Fourth Army was formed in France on 5 February 1916, under the command of Sir Henry Rawlinson. It was created in preparation for the Battle of the Somme after the French Tenth Army was transferred to the Battle of Verdun. On the first day on the Somme, eleven Fourth Army divisions (from XIII Corps, XV Corps, III Corps, X Corps and VIII Corps) attacked astride the Albert–Bapaume road. The attack was completely defeated on the northern sector, so subsequent Fourth Army operations concentrated on the southern sector, handing control of the northern sector to the Reserve Army. The plan for the Fourth Army during the Third Battle of Ypres (31 July – 10 November 1917), was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coats Observatory, Paisley
Coats Observatory is Scotland's oldest public observatory. It is currently closed for refurbishment as part of a 4-year long £42m transformation of the observatory and museum buildings. Located in Oakshaw Street West, Paisley, Renfrewshire, the observatory has been operational since 1 October 1883 and continues to function to this day, offering visitors the opportunity to view the night sky through the powerful telescopes housed within the building. The observatory is currently closed for redevelopment and is due to reopen in 2025. History Foundation of Coats Observatory The idea to create an observatory in Paisley came from the annual general meeting of the Paisley Philosophical Institution (PPI) held in 1880. The PPI was founded on 13 October 1808, having its origins among the educated and professional gentlemen of the burgh, such as ministers, doctors, lawyers and bankers. These 'noble pioneers of philosophy' [Gardner, P5] banded together with a view to improving themsel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astronomical Society Of Southern Africa
Astronomy is a natural science that studies celestial objects and the phenomena that occur in the cosmos. It uses mathematics, physics, and chemistry in order to explain their origin and their overall evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, meteoroids, asteroids, 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 Egyptians, Babylonians, Greeks, Indians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gill Medal Awarded To John Jackson
A gill () is a respiratory organ that many aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (: branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamellae (folds) contain blood or coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including molluscs, crustaceans, insects, fish, and amphibians. Semiterrestrial marine animals such as crabs and mudskippers have gill chambers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Total Eclipse
An eclipse is an astronomical event which occurs when an astronomical object or spacecraft is temporarily obscured, by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a ''syzygy''. An eclipse is the result of either an '' occultation'' (completely hidden) or a ''transit'' (partially hidden). A "deep eclipse" (or "deep occultation") is when a small astronomical object is behind a bigger one. "What is a deep eclipse? The smaller star is behind the bigger star" The term ''eclipse'' is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow. However, it can also refer to such events beyond the Earth–Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the ...

Harold Spencer Jones
Sir Harold Spencer Jones KBE FRS FRSE PRAS (29 March 1890 – 3 November 1960) was an English astronomer. He became renowned as an authority on positional astronomy and served as the tenth Astronomer Royal for 23 years. Although born "Jones", his surname became "Spencer Jones". Early life Harold Spencer Jones was born in Kensington, London, on 29 March 1890. His father, Henry Charles Jones, was an accountant and his mother, Sarah Ryland, had earlier worked as a school teacher. He was educated at Latymer Upper School, in Hammersmith, West London, from where he obtained a scholarship to Jesus College, Cambridge. He graduated there in 1911, and was awarded a postgraduate studentship. He subsequently became a Fellow of the college. Chief Assistant at the Royal Observatory, Greenwich, 1913–1923 In 1913 he was appointed Chief Assistant at the Royal Observatory, Greenwich, filling a vacancy created by the departure of Arthur Eddington to become Plumian Professor of Astrono ...

Stellar Parallax
Stellar parallax is the apparent shift of position (''parallax'') of any nearby star (or other object) against the background of distant stars. By extension, it is a method for determining the distance to the star through trigonometry, the stellar parallax method. Created by the different orbital positions of Earth, the extremely small observed shift is largest at time intervals of about six months, when Earth arrives at opposite sides of the Sun in its orbit, giving a baseline (the shortest side of the triangle made by a star to be observed and two positions of Earth) distance of about two astronomical units between observations. The parallax itself is considered to be half of this maximum, about equivalent to the observational shift that would occur due to the different positions of Earth and the Sun, a baseline of one astronomical unit (AU). Stellar parallax is so difficult to detect that its existence was the subject of much debate in astronomy for hundreds of years. Thomas ...

David Gill (astronomer)
Sir David Gill (12 June 1843 – 24 January 1914) was a Scottish astronomer who is known for measuring astronomical distances, for astrophotography and geodesy. He spent much of his career in South Africa. Life and work David Gill was born at 48 Skene Terrace in Aberdeen the son of David Gill, watchmaker and his wife Margaret Mitchell. He was educated first at Bellevue Academy in Aberdeen then at Dollar Academy. He spent two years at Aberdeen University, where he was taught by James Clerk Maxwell, and then joined his father's clock-making business. His most important influence at university was probably from Prof David Thomson. In 1863 they jointly repaired the university clock and both set up a new mechanical telescope at the Cromwell Tower Observatory. This was his introduction to astronomy. It would seem that Gill's interests lay elsewhere since after a few years he sold the business, and then spent time equipping Lord Lindsay's private observatory at Dun Echt, Aberd ...

Royal Observatory, Cape Of Good Hope
The Royal Observatory, Cape of Good Hope, is a former scientific institution in South Africa. Founded by the British Board of Longitude in 1820, its main building is now the headquarters building of the South African Astronomical Observatory. The institution was located on a small hill south-east from the centre of Cape Town. During the succeeding century a suburb of the city formed in the area; the suburb was named Observatory after the pre-existing Royal Observatory. It was declared a National Heritage Site in December 2018 and has also been the subject of an ICOMOS/IAU Case Study as a World Heritage Site. History The proposal for a Southern observatory in all likelihood originated among the same group of people who founded the Royal Astronomical Society in the United Kingdom. The official establishment of the Royal Observatory, Cape of Good Hope occurred on 20 October 1820 through an Order in Council of King George IV of the United Kingdom. It remained a separate entit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
