Thomas George Cowling
Thomas George Cowling FRS (17 June 1906 – 16 June 1990) was an English astronomer. Early life and education Cowling was born in Hackney, London, the second of four sons of George Cowling and Edith Eliza Cowling (née Nicholls). He was educated at Sir George Monoux Grammar School in Walthamstow and read mathematics at Brasenose College, Oxford from 1924 to 1930. From 1928 to 1930 he worked under Edward Arthur Milne. In 1929, Milne had no problems left to ask his student to work on and appealed to Sydney Chapman, who proposed that they work on an article on which he was working that dealt with the Sun's magnetic field. Cowling found an error in the paper that invalidated Chapman's results. After Cowling's doctorate, Chapman proposed that they work together. Academic career In 1933 Cowling wrote an article, ''The magnetic field of sunspots''. Joseph Larmor had worked in this area, arguing that sunspots regenerate themselves through a dynamo effect. Cowling showed that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hackney, London
Hackney is a district in East London, England, forming around two-thirds of the area of the modern London Borough of Hackney, to which it gives its name. It is 4 miles (6.4 km) northeast of Charing Cross and includes part of the Queen Elizabeth Olympic Park. Historically it was within the county of Middlesex. In the past it was also referred to as ''Hackney Proper'' to distinguish it from the Hackney Central, village which subsequently developed in the vicinity of Mare Street, the term ''Hackney Proper'' being applied to the wider district. Hackney is a large district, whose long established boundaries encompass the sub-districts of Homerton, Dalston (including Kingsland and Shacklewell), De Beauvoir Town, Upper Clapton, Upper and Lower Clapton, Stamford Hill, Hackney Central, Hackney Wick, South Hackney and West Hackney. Governance Hackney was an administrative unit with consistent boundaries from the early Middle Ages to the creation of the larger modern borough ...

Dynamo Effect
In physics, the dynamo theory proposes a mechanism by which a celestial body such as Earth or a star generates a magnetic field. The dynamo theory describes the process through which a rotating, convecting, and electrically conducting fluid can maintain a magnetic field over astronomical time scales. A dynamo is thought to be the source of the Earth's magnetic field and the magnetic fields of Mercury and the Jovian planets. History of theory When William Gilbert published ''De Magnete'' in 1600, he concluded that the Earth is magnetic and proposed the first hypothesis for the origin of this magnetism: permanent magnetism such as that found in lodestone. In 1822, André-Marie Ampère proposed that internal currents are responsible for Earth's magnetism. In 1919, Joseph Larmor proposed that a dynamo might be generating the field. However, even after he advanced his hypothesis, some prominent scientists advanced alternative explanations. The Nobel Prize winner Patrick Blacket ...

Emeritus
''Emeritus/Emerita'' () is an honorary title granted to someone who retires from a position of distinction, most commonly an academic faculty position, but is allowed to continue using the previous title, as in "professor emeritus". In some cases, the term is conferred automatically upon all persons who retire at a given rank, but in others, it remains a mark of distinguished performance (usually in the area of research) awarded selectively on retirement. It is also used when a person of distinction in a profession retires or hands over the position, enabling their former rank to be retained in their title. The term ''emeritus'' does not necessarily signify that a person has relinquished all the duties of their former position, and they may continue to exercise some of them. In descriptions of deceased professors emeriti listed at U.S. universities, the title ''emeritus'' is replaced by an indication of the years of their appointments, except in obituaries, where it may be us ...

Selig Brodetsky
Selig Brodetsky (; 10 February 1888 – 18 May 1954) was an English mathematician, a member of the World Zionist Executive, the president of the Board of Deputies of British Jews, and the second president of the Hebrew University of Jerusalem. Background Brodetsky was born in Olviopol (now Pervomaisk) in the Kherson Governorate of the Russian Empire (present-day Ukraine), the second of 13 children born to Akiva Brodetsky (the beadle of the local synagogue) and Adel (Prober). As a child, he witnessed the murder of his uncle in a pogrom. In 1894, the family followed Akiva to the East End of London, to where he had migrated a year earlier. Brodetsky attended the Jews' Free School, where he excelled at his studies. He was awarded a scholarship, which enabled him to attend the Central Foundation Boys' School of London and subsequently, in 1905, Trinity College, Cambridge. In 1908, he completed his studies with highest honours being Senior Wrangler, to the distress of the cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Applied Mathematics
Applied mathematics is the application of mathematics, mathematical methods by different fields such as physics, engineering, medicine, biology, finance, business, computer science, and Industrial sector, industry. Thus, applied mathematics is a combination of mathematical science and specialized knowledge. The term "applied mathematics" also describes the profession, professional specialty in which mathematicians work on practical problems by formulating and studying mathematical models. In the past, practical applications have motivated the development of mathematical theories, which then became the subject of study in pure mathematics where abstract concepts are studied for their own sake. The activity of applied mathematics is thus intimately connected with research in pure mathematics. History Historically, applied mathematics consisted principally of Mathematical analysis, applied analysis, most notably differential equations; approximation theory (broadly construed, ...

Lecturer
Lecturer is an academic rank within many universities, though the meaning of the term varies somewhat from country to country. It generally denotes an academic expert who is hired to teach on a full- or part-time basis. They may also conduct research. Comparison The table presents a broad overview of the traditional main systems, but there are universities which use a combination of those systems or other titles.

Helioseismology
Helioseismology is the study of the structure and dynamics of the Sun through its oscillations. These are principally caused by sound waves that are continuously driven and damped by convection near the Sun's surface. It is similar to geoseismology, or asteroseismology, which are respectively the studies of the Earth or stars through their oscillations. While the Sun's oscillations were first detected in the early 1960s, it was only in the mid-1970s that it was realized that the oscillations propagated throughout the Sun and could allow scientists to study the Sun's deep interior. The term was coined by Douglas Gough in the 90s. The modern field is separated into global helioseismology, which studies the Sun's resonant modes directly, and local helioseismology, which studies the propagation of the component waves near the Sun's surface. Helioseismology has contributed to a number of scientific breakthroughs. The most notable was to show that the anomaly in the predicted neutri ...
