Allen was born at Subiaco, Perth the third child of James Bernard Allen (died 1912), a South Australian-born lecturer in physics at Perth Technical School, and his wife Alice Hooper, ''née'' Aitken, a New Zealand-born trained nurse. Cla (as he was known) was educated at the High School, Perth, Western Australia and the University of Western Australia (B.Sc., 1926; M.Sc., 1929; D.Sc., 1936). Allen was appointed to a research fellowship at the newly established Commonwealth Solar Observatory in 1926 at Mount Stromlo, Australian Capital Territory, becoming an assistant there in 1928. Allen observed the 1 October 1940 solar eclipse in South Africa and obtained important results on the solar corona, including measurements of its electron density which were to prove invaluable to radio ast ...

Solar Eclipse Of October 1, 1940
A total solar eclipse occurred on October 1, 1940. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality was visible from Colombia, Brazil, Venezuela and South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring coun ....

Mill Hill
Mill Hill is a suburb in the London Borough of Barnet, England. It is situated around northwest of Charing Cross. Mill Hill was in the historic county of Middlesex until 1965, when it became part of Greater London. Its population counted 18,451 inhabitants as of 2011. Mill Hill consists of several distinct parts: the original Mill Hill Village; the later-developed Mill Hill Broadway (now the main hub of the area); and Mill Hill East - alongside large swathes of countryside. A further area at the western edge of the suburb, The Hale, is on the borders of Mill Hill and Edgware, and is partly in each. History The area's name was first recorded as Myllehill in 1547 and appears to mean "hill with a windmill". However, the workings of the original Mill are in the building adjacent to The Mill Field. Mill Hill Village is the oldest known inhabited part of the district, a ribbon development along a medieval route called 'The Ridgeway'. It is thought that the name 'Mill Hill' may ...

Harrie Massey
Sir Harrie Stewart Wilson Massey (16 May 1908 – 27 November 1983) was an Australian mathematical physicist who worked primarily in the fields of atomic and atmospheric physics. A graduate of the University of Melbourne and Cambridge University, where he earned his doctorate at the Cavendish Laboratory, Massey became an independent lecturer in Mathematical Physics at the Queen's University of Belfast in 1933. He was appointed Goldsmid Professor of Applied Mathematics at University College London, in 1938. During the Second World War, Massey worked at the Admiralty Research Laboratory , where he helped devise countermeasures for German magnetic naval mines, and at the Admiralty Mining Establishment in Havant, where he helped develop British naval mines. In 1943, Mark Oliphant persuaded the Admiralty to release Massey to work on the Manhattan Project. He joined Oliphant's British Mission at the Radiation Laboratory at the University of California, where they worked on the ...

Solar Corona
A corona ( coronas or coronae) is the outermost layer of a star's atmosphere. It consists of plasma. The Sun's corona lies above the chromosphere and extends millions of kilometres into outer space. It is most easily seen during a total solar eclipse, but it is also observable with a coronagraph. Spectroscopic measurements indicate strong ionization in the corona and a plasma temperature in excess of , much hotter than the surface of the Sun, known as the photosphere. The word ''corona'' is , in turn derived . History In 1724, French-Italian astronomer Giacomo F. Maraldi recognized that the aura visible during a solar eclipse belongs to the Sun, not to the Moon. In 1809, Spanish astronomer José Joaquín de Ferrer coined the term 'corona'. Based in his own observations of the 1806 solar eclipse at Kinderhook (New York), de Ferrer also proposed that the corona was part of the Sun and not of the Moon. English astronomer Norman Lockyer identified the first element unknown ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Australian Capital Territory
The Australian Capital Territory (commonly abbreviated as ACT), known as the Federal Capital Territory (FCT) until 1938, is a landlocked federal territory of Australia containing the national capital Canberra and some surrounding townships. It is located in southeastern Australian mainland as an enclave completely within the state of New South Wales. Founded after Federation as the seat of government for the new nation, the territory hosts the headquarters of all important institutions of the Australian Government. On 1 January 1901, federation of the colonies of Australia was achieved. Section 125 of the new Australian Constitution provided that land, situated in New South Wales and at least from Sydney, would be ceded to the new federal government. Following discussion and exploration of various areas within New South Wales, the '' Seat of Government Act 1908'' was passed in 1908 which specified a capital in the Yass-Canberra region. The territory was transferred to the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
