Arthur Pollen
Arthur Joseph Hungerford Pollen (13 September 1866 – 28 January 1937) was an English journalist, businessman, and commentator on naval affairs who devised a new computerised fire-control system for use on battleships prior to the First World War. His most important technical innovation was one of the world's first electrically-powered analogue computers, patented as the Argo Clock: a differential analyser which enabled big guns to engage with long-range targets when both ships were moving at speed in different directions. Early life Pollen was born on 13 September 1866, the sixth son and eighth child of eight sons and two daughters born to John Hungerford Pollen and Maria Margaret Pollen. His father being a leading convert to Catholicism along with Cardinal Newman, Arthur was educated at the school which the latter founded in Birmingham, The Oratory School (1878–1884). He then went up to read Modern History at Trinity College, Oxford where he gained a second-class degree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fire-control System
A fire-control system (FCS) is a number of components working together, usually a gun data computer, a director, and radar, which is designed to assist a ranged weapon system to target, track, and hit a target. It performs the same task as a human gunner firing a weapon, but attempts to do so faster and more accurately. Naval based fire control Origins The original fire-control systems were developed for ships. The early history of naval fire control was dominated by the engagement of targets within visual range (also referred to as direct fire). In fact, most naval engagements before 1800 were conducted at ranges of . Even during the American Civil War, the famous engagement between and was often conducted at less than range. Rapid technical improvements in the late 19th century greatly increased the range at which gunfire was possible. Rifled guns of much larger size firing explosive shells of lighter relative weight (compared to all-metal balls) so greatly increa ...

Edmund Widdrington Byrne
Sir Edmund Widdrington Byrne (30 June 1844 – 4 April 1904) was a British judge and Conservative Party politician. Life Byrne was born in Islington, London, and was the son of Edmund Byrne, solicitor, and his wife Mary Elizabeth, née Cowell. He was educated at King's College London and was called to the bar at Lincoln's Inn in 1867. In 1874, he married Henrietta Gulland of Newton Wemyss, Fife. He established a conveyancing and equity practice, and "took silk" to become a Queen's Counsel in 1888, and attached himself to the court of Mr Justice Chitty. In 1892 he was selected to contest the South Western or Walthamstow Division of Essex as the candidate of the Conservative Party. He was elected, and retained the seat with an increased majority at the ensuing election in 1895. In January 1897, Mr Justice Chitty retired, and Byrne was selected to fill the vacancy as a judge of the Chancery Division of the High Court of Justice. This required him to resign his seat in parlia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yaw Angle
The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system.Novi Commentarii academiae scientiarum Petropolitanae 20, 1776, pp. 189–207 (E478PDF/ref> They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in 3-dimensional linear algebra. Alternative forms were later introduced by Peter Guthrie Tait and George H. Bryan intended for use in aeronautics and engineering. Chained rotations equivalence Euler angles can be defined by elemental geometry or by composition of rotations. The geometrical definition demonstrates that three composed ''elemental rotations'' (rotations about the axes of a coordinate system) are always sufficient to reach any target frame. The three elemental rotations may be extrinsic (rotations about the axes ''xyz'' of the original coordinate system, which is assumed to remain motionless), or intrinsic ( ...

Differential Analyser
The differential analyser is a mechanical analogue computer designed to solve differential equations by integration, using wheel-and-disc mechanisms to perform the integration. It was one of the first advanced computing devices to be used operationally. The original machines could not add, but then it was noticed that if the two wheels of a rear differential are turned, the drive shaft will compute the average of the left and right wheels. A simple gear ratio of 1:2 then enables multiplication by two, Multiplication is just a special case of integration, namely integrating a constant function. History Research on solutions for differential equations using mechanical devices, discounting planimeters, started at least as early as 1836, when the French physicist Gaspard-Gustave Coriolis designed a mechanical device to integrate differential equations of the first order. The first description of a device which could integrate differential equations of any order was published in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Thomson (engineer)
James Thomson FRS FRSE LLD (16 February 1822 – 8 May 1892) was a British engineer and physicist, born in Belfast, and older brother of William Thomson (Lord Kelvin). Biography Born in Belfast, much of his youth was spent in Glasgow. His father James was professor of mathematics at the University of Glasgow from 1832 onward and his younger brother William was to become Baron Kelvin. James attended Glasgow University from a young age and graduated (1839) with high honours in his late teens. After graduation, he served brief apprenticeships with practical engineers in several domains; and then gave a considerable amount of his time to theoretical and mathematical engineering studies, often in collaboration with his brother, during his twenties in Glasgow. In his late twenties he entered into private practice as a professional engineer with special expertise in water transport. In his early thirties, in 1855, he was appointed professor of civil engineering at Queen's Universi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Thomson, 1st Baron Kelvin
William Thomson, 1st Baron Kelvin, (26 June 182417 December 1907) was a British mathematician, mathematical physicist and engineer born in Belfast. Professor of Natural Philosophy at the University of Glasgow for 53 years, he did important work in the mathematical analysis of electricity and formulation of the first and second laws of thermodynamics, and did much to unify the emerging discipline of physics in its contemporary form. He received the Royal Society's Copley Medal in 1883, was its president 1890–1895, and in 1892 was the first British scientist to be elevated to the House of Lords. Absolute temperatures are stated in units of kelvin in his honour. While the existence of a coldest possible temperature ( absolute zero) was known prior to his work, Kelvin is known for determining its correct value as approximately −273.15 degrees Celsius or −459.67 degrees Fahrenheit. The Joule–Thomson effect is also named in his honour. He worked closely with mathematics ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malta
Malta ( , , ), officially the Republic of Malta ( mt, Repubblika ta' Malta ), is an island country in the Mediterranean Sea. It consists of an archipelago, between Italy and Libya, and is often considered a part of Southern Europe. It lies south of Sicily (Italy), east of Tunisia, and north of Libya. The official languages are Maltese and English, and 66% of the current Maltese population is at least conversational in the Italian language. Malta has been inhabited since approximately 5900 BC. Its location in the centre of the Mediterranean has historically given it great strategic importance as a naval base, with a succession of powers having contested and ruled the islands, including the Phoenicians and Carthaginians, Romans, Greeks, Arabs, Normans, Aragonese, Knights of St. John, French, and British, amongst others. With a population of about 516,000 over an area of , Malta is the world's tenth-smallest country in area and fourth most densely populated sovereign cou ...

Clare Asquith
Mary Clare Asquith, Countess of Oxford and Asquith ( née Pollen; 2 June 1951) is an English independent scholar and author of ''Shadowplay: the Hidden Beliefs and Coded Politics of William Shakespeare'', in which she posited that Shakespeare was a covert Catholic, whose works contain coded language used by the Catholic underground, particularly England's Jesuits, but also appealed to the monarchy for toleration. Her book was the first to claim the existence of such a code as a subtext in Shakespeare.Vanessa ThorpShakespeare was a political rebel who wrote in code, claims author''The Guardian'', 28 August 2005. Retrieved 6 November 2011. Works Asquith's work was hailed by some, including the Catholic writer Piers Paul Read, as "dramatic, important" and "painstaking scholarship".

Linotype Machine
The Linotype machine ( ) is a "line casting" machine used in printing; manufactured and sold by the former Mergenthaler Linotype Company and related It was a hot metal typesetting system that cast lines of metal type for individual uses. Linotype became one of the mainstay methods to set type, especially small-size body text, for newspapers, magazines, and posters from the late 19th century to the 1970s and 1980s, when it was largely replaced by phototypesetting and digital typesetting. The name of the machine comes from the fact that it produces an entire line of metal type at once, hence a ''line-o'-type''. It was a significant improvement over the previous industry standard of manual, letter-by-letter typesetting using a composing stick and shallow subdivided trays, called "cases". The Linotype machine operator enters text on a 90-character keyboard. The machine assembles ''matrices'', which are molds for the letter forms, in a line. The assembled line is then cast ...
