Friedel Sellschop
Jacques Pierre Friederich (Friedel) Sellschop (8 June 1930 – 4 August 2002) was a South African scientist and pioneer in the field of applied physics, applied nuclear physics. Early life and education Sellschop was born in Luderitz, Namibia on 8 June 1930. He was educated at University of Pretoria (BSc) and Stellenbosch University (MSc), and earned a PhD in Nuclear Physics at University of Cambridge. On completing his education in England, he returned to South Africa on the advice of Basil Schonland, his mentor. Contributions to neutrino research In February 1965, Sellschop was part of a group which identified the first neutrino found in nature, in one of South Africa, South Africa's gold mines. The experiment was performed in a specially prepared chamber at a depth of 3 km in the East Rand Mine, ERPM mine near Boksburg. A plaque in the main building commemorates the discovery. The experiments also implemented a primitive neutrino astronomy and looked at issues of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basil Schonland
Sir Basil Ferdinand Jamieson Schonland OMG CBE FRS (2 February 1896 – 24 November 1972) was noted for his research on lightning, his involvement in the development of radar during World War II and for being the first president of the South African Council for Scientific and Industrial Research. Birth and parentage He was born in Grahamstown, Cape Colony to Selmar Schonland (botanist and a founder of Rhodes University) and Flora MacOwan, daughter of Peter MacOwan. Education In 1910, Schonland matriculated at the age of 14 from St. Andrew's College as the top pupil in the Cape Province. He later studied at Rhodes University and Gonville and Caius College, Cambridge in the years 1914-15 and 1919-20.

He was wounded at Arras, mentioned in despatches and was awarded the OBE. Early research After the war he became a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Physica Status Solidi A
''Physica Status Solidi'', often stylized ''physica status solidi'' or ''pss'', is a family of international peer-reviewed, scientific journals, publishing research on all aspects of solid state physics, and materials science. It is owned and published by Wiley–VCH. These journals publish over 2000 articles per year, making it one of the largest international publications in condensed matter physics. The current editor in chief is Stefan Hildebrandt at the Editorial Office based in Berlin. This office also manages the peer-review process. History ''Physica Status Solidi'' was founded by Karl Wolfgang Böer (then at Humboldt University of Berlin) in East Berlin and published its first issue in July 1961. Shortly after the journal was founded, the construction of the Berlin Wall in August 1961 exacerbated the distances between scientists from the Eastern and Western blocs. Throughout the cold war ''Physica Status Solidi'' maintained political independence and English as publi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nature (journal)
''Nature'' is a British weekly scientific journal founded and based in London, England. As a multidisciplinary publication, ''Nature'' features peer-reviewed research from a variety of academic disciplines, mainly in science and technology. It has core editorial offices across the United States, continental Europe, and Asia under the international scientific publishing company Springer Nature. ''Nature'' was one of the world's most cited scientific journals by the Science Edition of the 2019 ''Journal Citation Reports'' (with an ascribed impact factor of 42.778), making it one of the world's most-read and most prestigious academic journals. , it claimed an online readership of about three million unique readers per month. Founded in autumn 1869, ''Nature'' was first circulated by Norman Lockyer and Alexander Macmillan as a public forum for scientific innovations. The mid-20th century facilitated an editorial expansion for the journal; ''Nature'' redoubled its efforts in exp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CERN
The European Organization for Nuclear Research, known as CERN (; ; ), is an intergovernmental organization that operates the largest particle physics laboratory in the world. Established in 1954, it is based in a northwestern suburb of Geneva, on the France–Switzerland border. It comprises 23 member states, and Israel (admitted in 2013) is currently the only non-European country holding full membership. CERN is an official United Nations General Assembly observer. The acronym CERN is also used to refer to the laboratory; in 2019, it had 2,660 scientific, technical, and administrative staff members, and hosted about 12,400 users from institutions in more than 70 countries. In 2016, CERN generated 49 petabytes of data. CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research — consequently, numerous experiments have been constructed at CERN through international collaborations. CERN is the site of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diamond
Diamond is a Allotropes of carbon, solid form of the element carbon with its atoms arranged in a crystal structure called diamond cubic. Another solid form of carbon known as graphite is the Chemical stability, chemically stable form of carbon at Standard conditions for temperature and pressure, room temperature and pressure, but diamond is metastable and converts to it at a negligible rate under those conditions. Diamond has the highest Scratch hardness, hardness and thermal conductivity of any natural material, properties that are used in major industrial applications such as cutting and polishing tools. They are also the reason that diamond anvil cells can subject materials to pressures found deep in the Earth. Because the arrangement of atoms in diamond is extremely rigid, few types of impurity can contaminate it (two exceptions are boron and nitrogen). Small numbers of lattice defect, defects or impurities (about one per million of lattice atoms) color diamond blue (bor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Boksburg
Boksburg is a city on the East Rand of Gauteng province of South Africa. Gold was discovered in Boksburg in 1887. Boksburg was named after the State Secretary of the South African Republic, W. Eduard Bok. The Main Reef Road linked Boksburg to all the other major mining towns on the Witwatersrand and the Angelo Hotel (1887) was used as a staging post. Boksburg is part of the City of Ekurhuleni Metropolitan Municipality, that forms the local government of most of the East Rand. The Mining Commissioner Montague White built a large dam which, empty for years, was dubbed White's Folly until a flash flood in 1889 silenced detractors. The 150,000 square metre dam is now the Boksburg Lake, and is surrounded by lawns, trees, and terraces. History Prior to 1860, the present municipal area of Boksburg and its immediate environs comprised mainly the highveld farms called Leeuwpoort, Klippoortje, Klipfontein and Driefontein. Carl Ziervogel bought the farm Leeuwpoort in 1875 and for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East Rand Mine
East Rand Proprietary Mines (ERPM) is a 125-year-old underground gold mining operation on the Witwatersrand Basin at Boksburg, to the east of Johannesburg. The mine employed 3,850 people. It was the deepest mine in the world until 2008 at 3,585 metres depth, slightly more than the TauTona The TauTona Mine or Western Deep No.3 Shaft, was a gold mine in South Africa. At approximately deep, it was home to the world's second deepest mining operation, rivalled only by the Mponeng Gold Mine, but was closed in 2018. The mine was one o ... mine, also in South Africa, which was 3,581 metres at the time (in 2008 the TauTona mine completed a digging project that extended the depth of the mine by several hundred metres.) The mine closed in 2008. Historical gold production between 1896 and 2008 was 43 Moz at recovered gold grade of 8.1g/t (95% plant recovery). A world class high grade gold deposit remains with existing in situ resources (SAMREC compliant) of 63 Moz, including; - Measur ...
