George Gargrave
George Gargrave (1710–1785), was an English mathematician. Biography Gargrave was born in Leyburn, Yorkshire, in 1710. He was educated by his uncle, John Crow, a schoolmaster in that place. Under him he acquired a considerable knowledge of the classics and mathematics. His natural bent was towards astronomy, and in his after life he was reputed as one of the best proficients in the less recondite branches of that science in the north of England. In 1745 he became associated with Joseph Randall in the management of the academy at Heath, near Wakefield. The academy, though of good repute, did not pay, and was given up in 1754. Gargrave then started at Wakefield a mathematical school, with such success that in 1768 he retired on a handsome competency. He died on 7 December 1785, and was buried in the churchyard at Wensley. Personal Gargrave was a musician of some skill, and his handwriting was remarkably clear and fine. He possessed a large and well-selected library, and a fine ...

English People
The English people are an ethnic group and nation native to England, who speak the English language, a West Germanic language, and share a common history and culture. The English identity is of Anglo-Saxon origin, when they were known in Old English as the ('race or tribe of the Angles'). Their ethnonym is derived from the Angles, one of the Germanic peoples who migrated to Great Britain around the 5th century AD. The English largely descend from two main historical population groups the West Germanic tribes (the Angles, Saxons, Jutes and Frisians) who settled in southern Britain following the withdrawal of the Romans, and the partially Romanised Celtic Britons already living there.Martiniano, R., Caffell, A., Holst, M. et al.

Mathematician
A mathematician is someone who uses an extensive knowledge of mathematics in their work, typically to solve mathematical problems. Mathematicians are concerned with numbers, data, quantity, mathematical structure, structure, space, Mathematical model, models, and mathematics#Calculus and analysis, change. History One of the earliest known mathematicians were Thales of Miletus (c. 624–c.546 BC); he has been hailed as the first true mathematician and the first known individual to whom a mathematical discovery has been attributed. He is credited with the first use of deductive reasoning applied to geometry, by deriving four corollaries to Thales' Theorem. The number of known mathematicians grew when Pythagoras of Samos (c. 582–c. 507 BC) established the Pythagoreans, Pythagorean School, whose doctrine it was that mathematics ruled the universe and whose motto was "All is number". It was the Pythagoreans who coined the term "mathematics", and with whom the study of mathemat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leyburn
Leyburn is a market town and civil parish in the district of Richmondshire, North Yorkshire, England, sitting above the northern bank of the River Ure in Wensleydale. Historically in the North Riding of Yorkshire, the name was derived from 'Ley' or 'Le' (clearing), and 'burn' (stream), meaning clearing by the stream. Leyburn had a population of 1,844 at the 2001 census increasing to 2,183 at the 2011 Census. The estimated population in 2015 was 2,190. History Leyburn was mentioned in the Domesday Book of 1086 but had no recorded population; the growth of Leyburn as a major hub is linked to the decline in fortunes of nearby Wensley, which had prominence as the only market town in Wensleydale until being devastated by the plague in 1563, leaving what was once an important and prosperous town, mostly abandoned. Leyburn's stature increased in the 17th century when a market charter was granted by Charles II in 1686. Leyburn Town Hall was built in 1856 by Lord Bolton, and ...

Yorkshire
Yorkshire ( ; abbreviated Yorks), formally known as the County of York, is a historic county in northern England and by far the largest in the United Kingdom. Because of its large area in comparison with other English counties, functions have been undertaken over time by its subdivisions, which have also been subject to periodic reform. Throughout these changes, Yorkshire has continued to be recognised as a geographic territory and cultural region. The name is familiar and well understood across the United Kingdom and is in common use in the media and the military, and also features in the titles of current areas of civil administration such as North Yorkshire, South Yorkshire, West Yorkshire and the East Riding of Yorkshire. Within the borders of the historic county of Yorkshire are large stretches of countryside, including the Yorkshire Dales, North York Moors and Peak District national parks. Yorkshire has been nicknamed "God's Own Country" or "God's Own County" by its in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, 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 atmosphere of Earth, 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 Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

Wakefield
Wakefield is a cathedral city in West Yorkshire, England located on the River Calder. The city had a population of 99,251 in the 2011 census.https://www.nomisweb.co.uk/census/2011/ks101ew Census 2011 table KS101EW Usual resident population, West Yorkshire – Wakefield BUASD, code E35000474 The city is the administrative centre of the wider City of Wakefield metropolitan district, which had a population of , the most populous district in England. It is part of the West Yorkshire Built-up Area and the Yorkshire and The Humber region. In 1888, it was one of the last group of towns to gain city status due to having a cathedral. The city has a town hall and county hall, as the former administrative centre of the city's county borough and metropolitan borough as well as county town to both the West Riding of Yorkshire and West Yorkshire, respectively.

Wensley, North Yorkshire
Wensley is a small village and civil parish in the Richmondshire district of North Yorkshire, England. It consists of a few homes and holiday cottage, an inn, a pub and a historic church. It is on the A684 road south-west of the market town of Leyburn. The River Ure passes through the village. The etymology of the name ultimately originates from a compound of an Old English form of the god Woden (attested ''Wednesleg'' 1212, earlier ''Wodnesleie'', see Wednesday). Wensley gives its name to the dale Wensleydale. For a century after its charter in 1202, Wensley had the only market in the dale and this continued into the 16th century. Plague struck Wensley in 1563, some surviving villagers fled to Leyburn, but the village recovered a century later when Charles Paulet built Bolton Hall in 1678 and became Duke of Bolton. In fact, Bolton Hall, is from the heart of Wensley, near Preston-under-Scar, Richmondshire; it was a rebuild after a fire in 1902. Wensley's Holy T ...

Gentleman's Magazine
''The Gentleman's Magazine'' was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted for almost 200 years, until 1922. It was the first to use the term ''magazine'' (from the French ''magazine'', meaning "storehouse") for a periodical. Samuel Johnson's first regular employment as a writer was with ''The Gentleman's Magazine''. History The original complete title was ''The Gentleman's Magazine: or, Trader's monthly intelligencer''. Cave's innovation was to create a monthly digest of news and commentary on any topic the educated public might be interested in, from commodity prices to Latin poetry. It carried original content from a stable of regular contributors, as well as extensive quotations and extracts from other periodicals and books. Cave, who edited ''The Gentleman's Magazine'' under the pen name "Sylvanus Urban", was the first to use the term ''magazine'' (meaning "storehouse") for a periodical. Contributions to the maga ...

Edmond Halley
Edmond (or Edmund) Halley (; – ) was an English astronomer, mathematician and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720. From an observatory he constructed on Saint Helena in 1676–77, Halley catalogued the southern celestial hemisphere and recorded a transit of Mercury across the Sun. He realised that a similar transit of Venus could be used to determine the distances between Earth, Venus, and the Sun. Upon his return to England, he was made a fellow of the Royal Society, and with the help of King Charles II of England, Charles II, was granted a master's degree from University of Oxford, Oxford. Halley encouraged and helped fund the publication of Isaac Newton's influential ''Philosophiæ Naturalis Principia Mathematica'' (1687). From observations Halley made in September 1682, he used Newton's laws of motion to compute the periodicity of Halley's Comet in his 1705 ''Synopsis of the Astronomy of Comets''. It was named afte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Of Venus
frameless, upright=0.5 A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black dot moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than three times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth. Transits of Venus are among the rarest of predictable astronomical phenomena. They occur in a pattern that generally repeats every 243 years, with pairs of transits eight years apart separated by long gaps of 121.5 years and 105.5 years. The periodicity is a reflection of the fact that the orbital periods ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eclipse Of The Moon
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. U ...

Sphere
A sphere () is a Geometry, geometrical object that is a solid geometry, three-dimensional analogue to a two-dimensional circle. A sphere is the Locus (mathematics), set of points that are all at the same distance from a given point in three-dimensional space.. That given point is the centre (geometry), centre of the sphere, and is the sphere's radius. The earliest known mentions of spheres appear in the work of the Greek mathematics, ancient Greek mathematicians. The sphere is a fundamental object in many fields of mathematics. Spheres and nearly-spherical shapes also appear in nature and industry. Bubble (physics), Bubbles such as soap bubbles take a spherical shape in equilibrium. spherical Earth, The Earth is often approximated as a sphere in geography, and the celestial sphere is an important concept in astronomy. Manufactured items including pressure vessels and most curved mirrors and lenses are based on spheres. Spheres rolling, roll smoothly in any direction, so mos ...
