Elizabeth Alexander (astronomer)
Frances Elizabeth Somerville Alexander (; 13 December 1908 – 15 October 1958) was a British geologist, academic, and physicist, whose wartime work with radar and radio led to early developments in radio astronomy and whose post-war work on the geology of Singapore is considered a significant foundation to contemporary research. Alexander earned her PhD from Newnham College, Cambridge, and worked in Radio Direction Finding at Singapore Naval Base from 1938 to 1941. In January 1941, unable to return to Singapore from New Zealand, she became Head of Operations Research in New Zealand's Radio Development Lab, Wellington. In 1945, Alexander correctly interpreted that anomalous radar signals picked up on Norfolk Island were caused by the sun. This interpretation became pioneering work in the field of radio astronomy, making her one of the first women scientists to work in that field, albeit briefly. Early life and studies Alexander was born Frances Elizabeth Somerville Caldwell on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Merton, Surrey
Merton is an ancient parish historically in Surrey, but which has since 1965 been part of Greater London (under its current name Merton Priory). It is bounded by Wimbledon, London, Wimbledon to the north, Mitcham to the east, Morden, Cheam and Cuddington, Surrey, Cuddington (Worcester Park and rest of Motspur Park) to the south and New Malden, (New) Malden to the west. The 1871 Ordnance Survey map records its area as (2.7 sq mi). The parish was and is centred on the 12th-century parish church of St Mary in Merton Park. As a result of the disestablishment of the vestry, vestries the parish became of two legal types and areas: religious and civil. It had in the late 19th century seen breakaway ecclesiastical parishes but the civic aspect in 1907 was transformed into Merton Urban District; this in turn was enlarged and empowered into the London Borough of Merton in 1965. Naming Merton Park is quite widely used as a name for the neighbourhood. Merton itself is a rarely used name, am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owen Thomas Jones
Owen Thomas Jones, FRS FGS (16 April 1878 – 5 May 1967) was a Welsh geologist. Education He was born in Beulah, near Newcastle Emlyn, Cardiganshire, the only son of David Jones and Margaret Thomas. He attended the local village school in Trewen before going to Pencader Grammar School in 1893. In 1896 he went up to University College, Aberystwyth, to study physics, graduating in 1900. He then went to Trinity College, Cambridge, and was awarded a B.A. degree in Natural Sciences (geology) in 1902. Career In 1903 he joined the British Geological Survey, working near his home in Carmarthenshire and Pembrokeshire. In 1910 he was appointed the first professor of geology in Aberystwyth. In 1913 he became professor of geology at the University of Manchester, and then, in 1930, Woodwardian Professor of Geology at the University of Cambridge (until 1943).

Internment
Internment is the imprisonment of people, commonly in large groups, without charges or intent to file charges. The term is especially used for the confinement "of enemy citizens in wartime or of terrorism suspects". Thus, while it can simply mean imprisonment, it tends to refer to preventive confinement rather than confinement ''after'' having been convicted of some crime. Use of these terms is subject to debate and political sensitivities. The word ''internment'' is also occasionally used to describe a neutral country's practice of detaining belligerent armed forces and equipment on its territory during times of war, under the Hague Convention of 1907. Interned persons may be held in prisons or in facilities known as internment camps (also known as concentration camps). The term ''concentration camp'' originates from the Spanish–Cuban Ten Years' War when Spanish forces detained Cuban civilians in camps in order to more easily combat guerrilla forces.

Ruby Payne-Scott
Ruby Violet Payne-Scott, BSc (Phys) MSc DipEd (Syd) (28 May 1912 – 25 May 1981) was an Australian pioneer in radiophysics and radio astronomy, and was one of two Antipodean women pioneers in radio astronomy and radio physics at the end of the second world war, Ruby Payne-Scott the Australian and Elizabeth Alexander the New Zealander. Both women suffered misogyny in their careers, and an unnecessary argument half a century later introduced competitiveness which did not exist at the time. The resolution of in favour of Alexander in no way detracts from the achievements of Ruby Payne-Scott. Early life and education Ruby Payne-Scott was born on 28 May 1912 in Grafton, New South Wales, the daughter of Cyril Payne-Scott and his wife Amy (née Neale). She later moved to Sydney to live with her aunt. There she attended the Penrith Public Primary School (1921–24), and the Cleveland-Street Girls' High School (1925–26), before completing her secondary schooling at Sydney Girls Hi ...

Norfolk Island Effect
Norfolk () is a ceremonial and non-metropolitan county in East Anglia in England. It borders Lincolnshire to the north-west, Cambridgeshire to the west and south-west, and Suffolk to the south. Its northern and eastern boundaries are the North Sea, with The Wash to the north-west. The county town is the city of Norwich. With an area of and a population of 859,400, Norfolk is a largely rural county with a population density of 401 per square mile (155 per km2). Of the county's population, 40% live in four major built up areas: Norwich (213,000), Great Yarmouth (63,000), King's Lynn (46,000) and Thetford (25,000). The Broads is a network of rivers and lakes in the east of the county, extending south into Suffolk. The area is protected by the Broads Authority and has similar status to a national park. History The area that was to become Norfolk was settled in pre-Roman times, (there were Palaeolithic settlers as early as 950,000 years ago) with camps along the higher land in th ...

Wellington
Wellington ( mi, Te Whanganui-a-Tara or ) is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the second-largest city in New Zealand by metro area, and is the administrative centre of the Wellington Region. It is the List of national capitals by latitude, world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate, and is the world's windiest city by average wind speed. Legends recount that Kupe discovered and explored the region in about the 10th century, with initial settlement by Māori people, Māori iwi such as Rangitāne and Muaūpoko. The disruptions of the Musket Wars led to them being overwhelmed by northern iwi such as Te Āti Awa by the early 19th century. Wellington's current form was originally designed by Captain William Mein Smith, the first Surveyor General for Edward Wakefield (New Zealand politician), Edward Wakefield ...

Fall Of Singapore
The Fall of Singapore, also known as the Battle of Singapore,; ta, சிங்கப்பூரின் வீழ்ச்சி; ja, シンガポールの戦い took place in the South–East Asian theatre of the Pacific War. The Empire of Japan captured the British stronghold of Singapore, with fighting lasting from 8 to 15 February 1942. Singapore was the foremost British military base and economic port in South–East Asia and had been of great importance to British interwar defence strategy. The capture of Singapore resulted in the largest British surrender in its history. Prior to the battle, Japanese General Tomoyuki Yamashita had advanced with about 30,000 men down the Malayan Peninsula in the Malayan campaign. The British erroneously considered the jungle terrain impassable, leading to a swift Japanese advance as Allied defences were quickly outflanked. The British Lieutenant-General, Arthur Percival, commanded 85,000 Allied troops at Singapore, although many u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flying Boat
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Direction-finding
Direction finding (DF), or radio direction finding (RDF), isin accordance with International Telecommunication Union (ITU)defined as radio location that uses the reception of radio waves to determine the direction in which a radio station or an object is located. This can refer to radio or other forms of wireless communication, including radar signals detection and monitoring (ELINT/ESM). By combining the direction information from two or more suitably spaced receivers (or a single mobile receiver), the source of a transmission may be located via triangulation. Radio direction finding is used in the navigation of ships and aircraft, to locate emergency transmitters for search and rescue, for tracking wildlife, and to locate illegal or interfering transmitters. RDF was important in combating German threats during both the World War II Battle of Britain and the long running Battle of the Atlantic. In the former, the Air Ministry also used RDF to locate its own fighter g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Captain (Royal Navy)
Captain (Capt) is a senior officer rank of the Royal Navy. It ranks above commander and below commodore and has a NATO ranking code of OF-5. The rank is equivalent to a colonel in the British Army and Royal Marines, and to a group captain in the Royal Air Force. There are similarly named equivalent ranks in the navies of many other countries. Seagoing captains In the Royal Navy, the officer in command of any warship of the rank of commander and below is informally referred to as "the captain" on board, even though holding a junior rank, but formally is titled "the commanding officer" (or CO). In former times, up until the nineteenth century, Royal Navy officers who were captains by rank and in command of a naval vessel were referred to as post-captains; this practice is now defunct. A Captain (D) or Captain Destroyers afloat was an operational commander responsible for the command of destroyer flotilla or squadron, for a decade plus after the Second World War. The title ...

Weathering
Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs ''in situ'' (on site, with little or no movement), and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity. Weathering processes are divided into ''physical'' and ''chemical weathering''. Physical weathering involves the breakdown of rocks and soils through the mechanical effects of heat, water, ice, or other agents. Chemical weathering involves the chemical reaction of water, atmospheric gases, and biologically produced chemicals with rocks and soils. Water is the principal agent behind both physical and chemical weathering, though atmospheric oxygen and carbon dioxide and the activities of biological organisms are also important. Chemical weathering by biological action is also known as biologic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
