Louis Napoleon George Filon
Louis Napoleon George Filon, FRS (22 November 1875 – 29 December 1937) was an English applied mathematician, famous for his research on classical mechanics and particularly the theory of elasticity and the mechanics of continuous media. He also developed a method for the numerical quadrature of oscillatory integrals, now known as ''Filon quadrature''. He was Vice Chancellor of the University of London from 1933 to 1935. Early life He was born at Saint-Cloud, near Paris, as the only child of Augustin Filon, the French ''littérateur'' who was appointed as the official tutor to the Prince Imperial. Accompanying the Prince Imperial in his exile, the Filon family came to England in 1878 and lived at Margate. He was educated at Herne House School in Margate. Career In 1894 Filon became a student at University College, London and received his BA in 1896 with a gold medal in Greek. He was appointed in the college as Demonstrator in Applied Mathematics under the supervision of Karl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Leigh Smeathman Hatton
Professor John Leigh Smeathman (27 May 1865 – 13 January 1933) was a mathematician and Principal of East London College, England, one of the founding colleges of what is now Queen Mary College, part of London University. He was also Vice Chancellor of London University in the 1930s. Early life Smeathman was born in Street Aston, near Rugby, Warwickshire. on 27 May 1865, the eldest son of Revd J L S Hatton, Rector of West Barkwith, Lincolnshire. He was educated at Hertford College, Oxford where he obtained an MA graduating with first class honours in 1889 and second class honours in physics a year later. He also later qualified as a barrister at Lincoln's Inn. He also studied geometry at Oxford as an undergraduate under Savilian Professor of Geometry James Joseph Sylvester.

Biharmonic Equation
In mathematics, the biharmonic equation is a fourth-order partial differential equation which arises in areas of continuum mechanics, including linear elasticity theory and the solution of Stokes flows. Specifically, it is used in the modeling of thin structures that react elastically to external forces. Notation It is written as :\nabla^4\varphi=0 or :\nabla^2\nabla^2\varphi=0 or :\Delta^2\varphi=0 where \nabla^4, which is the fourth power of the del operator and the square of the Laplacian operator \nabla^2 (or \Delta), is known as the biharmonic operator or the bilaplacian operator. In Cartesian coordinates, it can be written in n dimensions as: : \nabla^4\varphi=\sum_^n\sum_^n\partial_i\partial_i\partial_j\partial_j \varphi =\left(\sum_^n\partial_i\partial_i\right)\left(\sum_^n \partial_j\partial_j\right) \varphi. Because the formula here contains a summation of indices, many mathematicians prefer the notation \Delta^2 over \nabla^4 because the former makes clear ...

Photoelasticity
Photoelasticity describes changes in the optical properties of a material under mechanical deformation. It is a property of all dielectric media and is often used to experimentally determine the stress distribution in a material, where it gives a picture of stress distributions around discontinuities in materials. Photoelastic experiments (also informally referred to as ''photoelasticity'') are an important tool for determining critical stress points in a material, and are used for determining stress concentration in irregular geometries. History The photoelastic phenomenon was first discovered by the Scottish physicist David Brewster, who immediately recognized it as stress-induced birefringence. That diagnosis was confirmed in a direct refraction experiment by Augustin-Jean Fresnel.A. Fresnel, "Note sur la double réfraction du verre comprimé" (read 16 September 1822), ''Annales de Chimie et de Physique'', Ser. 2, vol. 20, pp. 376–83 (nominally f ...

List Of British University Chancellors And Vice-chancellors
This following is a current list of the chancellors, vice-chancellors and visitors of universities in the United Kingdom. In most cases, the chancellor is a ceremonial head, while the vice-chancellor is chief academic officer and chief executive. In Scotland, the principal is the chief executive and is usually ''ex officio'' vice-chancellor, which is a purely titular position. Long service Since the development of the university sector in the UK there have been several hundred individuals appointed to the role of Vice-Chancellor (or Director, President, Principal). A small number of Vice-Chancellors have served in this capacity for 15 years or more, with some portion of this time in office as a Vice-Chancellor in the UK. They include: 47 Years: George Baird (Edinburgh 1793-1840); 43 Years: Sir Henry Reichel (Bangor 1884-1927); 36 Years: George Campbell (Aberdeen 1759-95); 35 Years: Duncan Macfarland (Glasgow 1823-58), John Mackay (Dundee 1895-1930); 34 Years: Hector B ...

Croydon Typhoid Outbreak Of 1937
The Croydon typhoid outbreak of 1937, also known as the Croydon epidemic of typhoid fever, was an outbreak of typhoid fever in Croydon, Surrey, now part of London, in 1937. It resulted in 341 cases of typhoid (43 fatal), and it caused considerable local discontent leading to a media campaign and a public inquiry. The source of the illness remained a mystery until the cases were mapped out using epidemiological method. The origin was found to be the polluted chalk water well at Addington, London, which supplied water to up to one-fifth of the area that is now the London Borough of Croydon. Coupled with issues around the co-operation between the medical officers and the administrators of the Borough, three coincidental events were blamed; changes to the well structure by repair work, the employment of a new workman who was an unwitting carrier of typhoid, and failure to chlorinate the water. Background The Public Health Act 1848 gave local boards of health powers to improve the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Croydon
Croydon is a large town in south London, England, south of Charing Cross. Part of the London Borough of Croydon, a local government district of Greater London. It is one of the largest commercial districts in Greater London, with an extensive shopping district and night-time economy. The entire town had a population of 192,064 as of 2011, whilst the wider borough had a population of 384,837. Historically an ancient parish in the Wallington hundred of Surrey, at the time of the Norman conquest of England Croydon had a church, a mill, and around 365 inhabitants, as recorded in the Domesday Book of 1086. Croydon expanded in the Middle Ages as a market town and a centre for charcoal production, leather tanning and brewing. The Surrey Iron Railway from Croydon to Wandsworth opened in 1803 and was an early public railway. Later 19th century railway building facilitated Croydon's growth as a commuter town for London. By the early 20th century, Croydon was an important industria ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
