Brown (surname)
Brown is an English-language surname in origin chiefly descriptive of a person with brown hair, complexion or clothing. It is one of the most common surnames in English-speaking countries. It is the second most common surname in Canada and Scotland, third most common in Australia and the United Kingdom and fourth most common in England and the United States. It is particularly clustered in southern Scotland. Etymology and history of the surname Most occurrences of the name are derived from a nickname concerning the complexion of an individual, the colour of their hair or the clothing worn. This nickname is derived from the Old English ''brun'', ''brūn''; Middle English ''brun'', ''broun''; or Old French ''brun''. The root word is also sometimes found in Old English and Old Norse bynames, such as the Old Norse ''Brúnn''; however these names were not common after the Norman Conquest (in 1066). In some cases, the Old English personal name ''Brun'' may be a short form of one of s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottesmore School
Cottesmore is a Preparatory school (UK), preparatory school in the United Kingdom, founded in 1894. It is full boarding school, boarding. History Cottesmore was founded by Geoffrey Davison Brown in 1894 in Hove, East Sussex. He named the school after Cottesmore, Rutland, where he was born. The new buildings for the preparatory school were officially opened on 19 June 1897. Davison Brown served as headmaster until his death in 1929, aged 60. In 1940 the school was evacuated from the south coast of England, to Wales, initially to the Oakeley Arms Hotel, Tan-y-bwlch, Merioneth, and later to a former workhouse in Cors-y-Gedol Hall, near Barmouth, until the end of the war. The school moved to its present site at Pease Pottage after World War II in 1946. The school is housed in a Listed building, Grade II-listed Victorian architecture, Victorian mansion known as Buchan Hill that was built in 1882–3 by Philip Felix Renaud Saillard. The building is a large Elizabethan-style house, des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John William Sutton Pringle
Sir John William Sutton Pringle (22 July 1912 – 2 November 1982) was a British zoologist. His research interests were in insect physiology, especially proprioception, flight muscle, and cicada song. Life and career Pringle was born in 1912, and educated at Winchester College before going up to King's College, Cambridge where he took a first class degree in the Natural Sciences Tripos in 1934.

In 1959 he was appointed Reader in Experimental Cytology. In 1961 he moved to the Linacre Chair of Z ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rebecca/Eureka Transponding Radar
The Rebecca/Eureka transponding radar was a short-range radio navigation system used for the dropping of airborne forces and their supplies. It consisted of two parts, the Rebecca airborne transceiver and antenna system, and the Eureka ground-based transponder. Rebecca calculated the range to the Eureka based on the timing of the return signals, and its relative position using a highly directional antenna. The 'Rebecca' name comes from the phrase " Recognition of beacons". The 'Eureka' name comes from the Greek word meaning " I have found it!". The system was developed in the UK at the Telecommunications Research Establishment by Robert Hanbury Brown and John William Sutton Pringle. Rebecca was essentially an ASV radar fit to a new broadcaster unit, while the Eureka system was all-new. Initial production began in 1943, and the system was used for dropping supplies to resistance fighters in occupied Europe, after delivery of the portable Eureka unit. The US Army Air Force started pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chain Home
Chain Home, or CH for short, was the codename for the ring of coastal Early Warning radar stations built by the Royal Air Force (RAF) before and during the Second World War to detect and track aircraft. Initially known as RDF, and given the official name Air Ministry Experimental Station Type 1 (AMES Type 1) in 1940, the radar units themselves were also known as Chain Home for most of their life. Chain Home was the first early warning radar network in the world, and the first military radar system to reach operational status. Its effect on the outcome of the war made it one of the most powerful weapons of what is today known as the "Wizard War". In late 1934, the Tizard Committee asked radio expert Robert Watson-Watt to comment on the repeated claims of radio death rays and reports suggesting Germany had built some sort of radio weapon. His assistant, Arnold Wilkins, demonstrated that a death ray was impossible but suggested radio could be used for long-range detection. In Febr ...

Telecommunications Research Establishment
The Telecommunications Research Establishment (TRE) was the main United Kingdom research and development organization for radio navigation, radar, infra-red detection for heat seeking missiles, and related work for the Royal Air Force (RAF) during World War II and the years that followed. It was regarded as "the most brilliant and successful of the English wartime research establishments" under "Rowe, who saw more of the English scientific choices between 1935 and 1945 than any single man." The name was changed to Radar Research Establishment in 1953, and again to the Royal Radar Establishment in 1957. This article covers the precursor organizations and the Telecommunications Research Establishment up to the time of the name change. The later work at the site is described in the separate article about RRE. History TRE is best known for work on defensive and offensive radar. TRE also made substantial contributions to radio-navigation and to jamming enemy radio-navigation. Rad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Tizard
Sir Henry Thomas Tizard (23 August 1885 – 9 October 1959) was an English chemist, inventor and Rector of Imperial College, who developed the modern "octane rating" used to classify petrol, helped develop radar in World War II, and led the first serious studies of UFOs. Life Tizard was born in Gillingham, Kent in 1885, the only son of Thomas Henry Tizard (1839–1924), naval officer and hydrographer, and his wife, Mary Elizabeth Churchward. His ambition to join the navy was thwarted by poor eyesight, and he instead studied at Westminster School and Magdalen College, Oxford, where he concentrated on mathematics and chemistry, doing work on indicators and the motions of ions in gases. Tizard graduated in 1908 and at his tutor's suggestion he spent time in Berlin, where he met and formed a close friendship with Frederick Alexander Lindemann, later an influential scientific advisor of Winston Churchill. In 1909, he became a researcher in the Davy–Faraday Laboratory of the Roy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Bachelor's Degree
A bachelor's degree (from Middle Latin ''baccalaureus'') or baccalaureate (from Modern Latin ''baccalaureatus'') is an undergraduate academic degree awarded by colleges and universities upon completion of a course of study lasting three to six years (depending on institution and academic discipline). The two most common bachelor's degrees are the Bachelor of Arts (BA) and the Bachelor of Science (BS or BSc). In some institutions and educational systems, certain bachelor's degrees can only be taken as graduate or postgraduate educations after a first degree has been completed, although more commonly the successful completion of a bachelor's degree is a prerequisite for further courses such as a master's or a doctorate. In countries with qualifications frameworks, bachelor's degrees are normally one of the major levels in the framework (sometimes two levels where non-honours and honours bachelor's degrees are considered separately). However, some qualifications titled bachelor's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classics
Classics or classical studies is the study of classical antiquity. In the Western world, classics traditionally refers to the study of Classical Greek and Roman literature and their related original languages, Ancient Greek and Latin. Classics also includes Greco-Roman philosophy, history, archaeology, anthropology, art, mythology and society as secondary subjects. In Western civilization, the study of the Greek and Roman classics was traditionally considered to be the foundation of the humanities, and has, therefore, traditionally been the cornerstone of a typical elite European education. Etymology The word ''classics'' is derived from the Latin adjective '' classicus'', meaning "belonging to the highest class of citizens." The word was originally used to describe the members of the Patricians, the highest class in ancient Rome. By the 2nd century AD the word was used in literary criticism to describe writers of the highest quality. For example, Aulus Gellius, in his ''Att ...
