Hugh Longbourne Callendar
Hugh Longbourne Callendar (18 April 1863 – 21 January 1930) was a British physicist known for his contributions to the areas of thermometry and thermodynamics. Callendar was the first to design and build an accurate platinum resistance thermometer suitable for use, which allowed scientists and engineers to obtain consistent and accurate results. He conducted experiments and researched thermodynamics, producing and publishing reliable tables on the thermodynamic properties of steam used for calculations. Callendar worked with multiple institutions during World War I, helping to research and develop useful tools for the Navy. Callendar received awards such as the James Watt Medal of the Institution of Civil Engineers (1898) and the Rumford Medal (1906). He was elected as a Fellow of the Royal Society, and later a member of the Physical Society of London. Callendar was also nominated for the Nobel Prize in Physics three times. He died at home in Ealing, after an operation in 193 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hatherop
Hatherop is a village and civil parish in the Cotswolds Area of Outstanding Natural Beauty, about north of Fairford in Gloucestershire, England. The River Coln forms part of the western boundary of the parish. History Barrow Elm, which is about southeast of the village, is a prehistoric tumulus. The Domesday Book of 1086 lists Hatherop as ''Etherope'', derived from the Old English ''hēah'' and ''throp'' meaning "high outlying farmstead". The village and parish adjoin the parkland of Williamstrip, a 17th-century country house that was the seat of Michael Hicks Beach, the first Earl St Aldwyn. Hatherop Castle dates from the sixteenth or seventeenth century, but was partly rebuilt by the architect Henry Clutton for Baron de Mauley in 1850–56.Verey, 1970, page 270 The building is now a school. Clutton also rebuilt the Church of England parish church of Saint Nicholas for the same client in 1854–55. The architect and builder Richard Pace built Severalls as a re ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Association Football
Association football, more commonly known as football or soccer, is a team sport played between two teams of 11 players who primarily use their feet to propel the ball around a rectangular field called a pitch. The objective of the game is to score more goals than the opposition by moving the ball beyond the goal line into a rectangular framed goal defended by the opposing side. Traditionally, the game has been played over two 45 minute halves, for a total match time of 90 minutes. With an estimated 250 million players active in over 200 countries, it is considered the world's most popular sport. The game of association football is played in accordance with the Laws of the Game, a set of rules that has been in effect since 1863 with the International Football Association Board (IFAB) maintaining them since 1886. The game is played with a football that is in circumference. The two teams compete to get the ball into the other team's goal (between the posts and under t ...

Marlborough College
Marlborough College is a Public school (United Kingdom), public school (English Independent school (United Kingdom), independent boarding school) for pupils aged 13 to 18 in Marlborough, Wiltshire, England. Founded in 1843 for the sons of Church of England clergy, it is now Mixed-sex education, co-educational. For the academic year 2015/16, Marlborough charged £9,610 per term for day pupils, making it the most expensive day school in the Headmasters' and Headmistresses' Conference (HMC) – the association of British independent schools. The ''Good Schools Guide'' described Marlborough as a "famous, designer label, co-ed boarding school still riding high." The school is a member of the G20 Schools Group. A sister school in Johor, Malaysia opened in 2012. History Founded in 1843 for the education of the sons of Church of England clergy, the school now accepts both boys and girls of all beliefs.

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

Induction Coil
An induction coil or "spark coil" (archaically known as an inductorium or Ruhmkorff coil after Heinrich Rühmkorff) is a type of electrical transformer used to produce high-voltage pulses from a low-voltage direct current (DC) supply. p.98 To create the flux changes necessary to induce voltage in the secondary coil, the direct current in the primary coil is repeatedly interrupted by a vibrating mechanical contact called an interrupter. Invented in 1836 by Nicholas Callan, with additional research by Charles Grafton Page and others, the induction coil was the first type of transformer. It was widely used in x-ray machines, spark-gap radio transmitters, arc lighting and quack medical electrotherapy devices from the 1880s to the 1920s. Today its only common use is as the ignition coils in internal combustion engines and in physics education to demonstrate induction. Construction and function An induction coil consists of two coils of insulated wire wound around a common i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anglican
Anglicanism is a Western Christian tradition that has developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents worldwide . Adherents of Anglicanism are called ''Anglicans''; they are also called ''Episcopalians'' in some countries. The majority of Anglicans are members of national or regional ecclesiastical provinces of the international Anglican Communion, which forms the third-largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. These provinces are in full communion with the See of Canterbury and thus with the Archbishop of Canterbury, whom the communion refers to as its '' primus inter pares'' (Latin, 'first among equals'). The Archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physical Society Of London
The Physical Society of London, England, was a scientific society which was founded in 1874. In 1921, it was renamed the Physical Society, and in 1960 it merged with the Institute of Physics (IOP), the combined organisation eventually adopting the name of the latter society. The society was founded due to the efforts of Frederick Guthrie, Professor of Physics at the Royal College of Science, South Kensington, and his assistant, William Fletcher Barrett. They canvassed support for a 'Society for physical research' and on 14 February 1874, the Physical Society of London was formed with an initial membership of 29 people. The Society's first president was John Hall Gladstone. Meetings were held every two weeks, mainly at Imperial College London. From its beginning, the society held open meetings and demonstrations and published '' Proceedings of the Physical Society of London''. The first Guthrie lecture, now known as the Faraday Medal and Prize, was delivered in 1914. In 1921 the so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
