William Roy Piggott
William Roy Piggott (18 July 1914 – 20 May 2008) was a student of Sir Edward Appleton who transferred a large group of German specialists from Austria into the British Zone of Occupation in Germany in 1945. He edited the still valid official booklet of reduction rules for ionospheric soundings with Karl Rawer and was engaged in international activities during the International Geophysical Year (IGY) and for a long time afterwards. Biography Before the Second World War, Piggott was experimenting in nuclear physics. Seriously contaminated, he switched over to the Cavendish Laboratory Cambridge with studies of the ionosphere and of Shortwave propagation, then for many decades at Radio Research Station Slough, again under Sir Edward. In order to collect German scientific results in his field, when he was ordered to dissolve Walter Dieminger´s relevant German organization. When he came to Austria where the German group had arrived, he decided, despite his orders, to save that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir Edward Appleton
Sir Edward Victor Appleton (6 September 1892 – 21 April 1965) was an English physicist, Nobel Prize winner (1947) and pioneer in radiophysics. He studied, and was also employed as a lab technician, at Bradford College from 1909 to 1911. He won the Nobel Prize in Physics in 1947 for his seminal work proving the existence of the ionosphere during experiments carried out in 1924. Biography Appleton was born in Bradford, West Riding of Yorkshire, the son of Peter Appleton, a warehouseman, and Mary Wilcock, and was educated at Hanson Grammar School. In 1911, aged 18, he was awarded a scholarship to attend St John's College, Cambridge, where he graduated with First Class Honours in Natural Science with Physics in 1913. He was also a member of Isaac Newton University Lodge. In 1915, he married his first wife, Jessie Appleton (formerly Longson), with whom he had two kids.

Allied-occupied Germany
Germany was already de facto occupied by the Allies from the real fall of Nazi Germany in World War II on 8 May 1945 to the establishment of the East Germany on 7 October 1949. The Allies (United States, United Kingdom, Soviet Union, and France) asserted joint authority and sovereignty at the 1945 Berlin Declaration. At first, defining Allied-occupied Germany as all territories of the former German Reich before Nazi annexing Austria; however later in the 1945 Potsdam Conference of Allies, the Potsdam Agreement decided the new German border as it stands today. Said border gave Poland and the Soviet Union all regions of Germany (eastern parts of Pomerania, Neumark, Posen-West Prussia, Free City of Danzig, East-Prussia & Silesia) east of the Oder–Neisse line and divided the remaining "Germany as a whole" into the four occupation zones for administrative purposes under the three Western Allies (the United States, the United Kingdom, and France) and the Soviet Union.

Halley Research Station
Halley Research Station is a research facility in Antarctica on the Brunt Ice Shelf operated by the British Antarctic Survey (BAS). The base was established in 1956 to study the Earth's atmosphere. Measurements from Halley led to the discovery of the ozone hole in 1985. The current base is the sixth in a line of structures and includes design elements intended to overcome the challenge of building on a floating ice shelf without being buried and crushed by snow. , the base has been left unstaffed through winter since 2017, due to concerns over the propagation of an ice crack and how this might cut off the evacuation route in an emergency. The Halley Bay Important Bird Area with its emperor penguin colony lies in the general vicinity of the base. History Halley Bay base was founded in 1956, for the International Geophysical Year of 1957–1958, by an expedition from the Royal Society. The bay where the expedition decided to set up their base was named after the astronomer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Antarctic Survey
The British Antarctic Survey (BAS) is the United Kingdom's national polar research institute. It has a dual purpose, to conduct polar science, enabling better understanding of global issues, and to provide an active presence in the Antarctic on behalf of the UK. It is part of the Natural Environment Research Council (NERC). With over 400 staff, BAS takes an active role in Antarctic affairs, operating five research stations, one ship and five aircraft in both polar regions, as well as addressing key global and regional issues. This involves joint research projects with over 40 UK universities and more than 120 national and international collaborations. Having taken shape from activities during World War II, it was known as the Falkland Islands Dependencies Survey until 1962. History Operation Tabarin was a small British expedition in 1943 to establish permanently occupied bases in the Antarctic. It was a joint undertaking by the Admiralty and the Colonial Office.

Polar Region
The polar regions, also called the frigid zones or polar zones, of Earth are the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles. These high latitudes are dominated by floating sea ice covering much of the Arctic Ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica and the Southern Ocean in the south. Definitions The Arctic has various definitions, including the region north of the Arctic Circle (currently Epoch 2010 at 66°33'44" N), or just the region north of 60° north latitude, or the region from the North Pole north to the timberline. The Antarctic is usually defined simply as south of 60° south latitude, or the continent of Antarctica. The 1959 Antarctic Treaty uses the former definition. The two polar regions are distinguished from the other two climatic and biometric belts of Earth, a tropics belt near the equator, and two middle latitude regions located betwe ...

Ionogram
An ionosonde, or chirpsounder, is a special radar for the examination of the ionosphere. The basic ionosonde technology was invented in 1925 by Gregory Breit and Merle A. Tuve and further developed in the late 1920s by a number of prominent physicists, including Edward Victor Appleton. The term ''ionosphere'' and hence, the etymology of its derivatives, was proposed by Robert Watson-Watt. Components An ionosonde consists of: * A high frequency (HF) radio transmitter, automatically tunable over a wide range. Typically the frequency coverage is 0.5–23 MHz or 1–40 MHz, though normally sweeps are confined to approximately 1.6–12 MHz. * A tracking HF receiver which can automatically track the frequency of the transmitter. * An antenna with a suitable radiation pattern, which transmits well vertically upwards and is efficient over the whole frequency range used. * Digital control and data analysis circuits. The transmitter sweeps all or part of the HF frequency r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Union Of Radio Science
The International Union of Radio Science (abbreviated ''URSI'', after its French name, french: link=no, Union radio-scientifique internationale) is one of 26 international scientific unions affiliated to the International Council for Science (ICSU). History and objectives URSI was officially created in 1919, during the Constitutive Assembly of the International Research Council (now ICSU), based on the earlier french: link=no, Commission Internationale de Telegraphie sans Fil (1913–1914) when the only radio communication system was radiotelegraphy. It has held a general assembly every three years from 1922. Fifty years ago URSI was one of the most important promoters of the International Geophysical Year. It co-sponsors the ''Radio Science'' journal (co-sponsored by the American Geophysical Union) as well as the ''Journal of Atmospheric and Solar-Terrestrial Physics''. URSI's original objective (to encourage "scientific studies of radiotelegraphy, especially those which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Winston Churchill
Sir Winston Leonard Spencer Churchill (30 November 187424 January 1965) was a British statesman, soldier, and writer who served as Prime Minister of the United Kingdom twice, from 1940 to 1945 during the Second World War, and again from 1951 to 1955. Apart from two years between 1922 and 1924, he was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an economic liberal and imperialist, he was for most of his career a member of the Conservative Party, which he led from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924. Of mixed English and American parentage, Churchill was born in Oxfordshire to a wealthy, aristocratic family. He joined the British Army in 1895 and saw action in British India, the Anglo-Sudan War, and the Second Boer War, gaining fame as a war correspondent and writing books about his campaigns.

Austria
Austria, , bar, Östareich officially the Republic of Austria, is a country in the southern part of Central Europe, lying in the Eastern Alps. It is a federation of nine states, one of which is the capital, Vienna, the most populous city and state. A landlocked country, Austria is bordered by Germany to the northwest, the Czech Republic to the north, Slovakia to the northeast, Hungary to the east, Slovenia and Italy to the south, and Switzerland and Liechtenstein to the west. The country occupies an area of and has a population of 9 million. Austria emerged from the remnants of the Eastern and Hungarian March at the end of the first millennium. Originally a margraviate of Bavaria, it developed into a duchy of the Holy Roman Empire in 1156 and was later made an archduchy in 1453. In the 16th century, Vienna began serving as the empire's administrative capital and Austria thus became the heartland of the Habsburg monarchy. After the dissolution of the H ...
