Augustus Edward Hough Love
Augustus Edward Hough Love FRS (17 April 1863, Weston-super-Mare – 5 June 1940, Oxford), often known as A. E. H. Love, was a mathematician famous for his work on the mathematical theory of elasticity. He also worked on wave propagation and his work on the structure of the Earth in ''Some Problems of Geodynamics'' won for him the Adams prize in 1911 when he developed a mathematical model of surface waves known as Love waves. Love also contributed to the theory of tidal locking and introduced the parameters known as Love numbers, used in problems related to Earth tides, the tidal deformation of the solid Earth due to the gravitational attraction of the Moon and Sun. Life and career He was educated at Wolverhampton Grammar School and in 1881 won a scholarship to St John's College, Cambridge, where he was at first undecided whether to study classics or mathematics. His successful progress (he was placed Second Wrangler) vindicated his choice of mathematics, and in 1886 he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weston-super-Mare
Weston-super-Mare ( ) is a seaside town and civil parish in the North Somerset unitary district, in the county of Somerset, England. It lies by the Bristol Channel south-west of Bristol between Worlebury Hill and Bleadon Hill. Its population at the 2021 census was 82,418. The area around the town has been occupied since the Iron Age. It was still a small village until the 19th century when it developed as a seaside resort. A Weston-super-Mare railway station, railway station and two piers were built. In the second half of the 20th century it was connected to the M5 motorway but the number of people holidaying in the town declined and some local industries closed, although the number of day visitors has risen. Attractions include the Grand Pier, Weston-super-Mare, Grand Pier, Weston Museum and The Helicopter Museum.

Tidal Locking
Tidal locking between a pair of co-orbiting astronomical body, astronomical bodies occurs when one of the objects reaches a state where there is no longer any net change in its rotation rate over the course of a complete orbit. In the case where a tidally locked body possesses synchronous rotation, the object takes just as long to rotate around its own axis as it does to revolve around its partner. For example, the same side of the Moon always faces Earth, although there is some libration, variability because the Moon's orbit is not perfectly circular. Usually, only the natural satellite, satellite is tidally locked to the larger body. However, if both the difference in mass between the two bodies and the distance between them are relatively small, each may be tidally locked to the other; this is the case for Pluto and Charon (moon), Charon, and for Eris (dwarf planet), Eris and Dysnomia (moon), Dysnomia. Alternative names for the tidal locking process are gravitational locking, c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Twist (differential Geometry)
In differential geometry, the twist of a ''ribbon'' is its rate of axial rotation. Let a ribbon (X,U) be composed of a space curve, X=X(s), where s is the arc length of X, and U=U(s) a unit normal vector, perpendicular at each point to (s). Since the ribbon (X,U) has edges X and X'=X+\varepsilon U, the twist (or ''total twist number'') Tw measures the average winding of the edge curve X' around and along the axial curve X. According to Love (1944) twist is defined by : Tw = \dfrac \int \left( U \times \dfrac \right) \cdot \dfrac ds \; , where dX/ds is the unit tangent vector to X. The total twist number Tw can be decomposed (Moffatt & Ricca 1992) into ''normalized total torsion'' T \in Torsion of a curve">torsion of the space curve X, and \left[ \Theta \rightX denotes the total rotation angle of U along X. Neither N nor Tw are independent of the ribbon field U. Instead, only the normalized torsion T is an invariant of the curve X (Banchoff & White 1975). When the ribbon is de ...

London Mathematical Society
The London Mathematical Society (LMS) is one of the United Kingdom's Learned society, learned societies for mathematics (the others being the Royal Statistical Society (RSS), the Institute of Mathematics and its Applications (IMA), the Edinburgh Mathematical Society and the Operational Research Society (ORS). History The Society was established on 16 January 1865, the first president being Augustus De Morgan. The earliest meetings were held in University College London, University College, but the Society soon moved into Burlington House, Piccadilly. The initial activities of the Society included talks and publication of a journal. The LMS was used as a model for the establishment of the American Mathematical Society in 1888. Mary Cartwright was the first woman to be President of the LMS (in 1961–62). The Society was granted a royal charter in 1965, a century after its foundation. In 1998 the Society moved from rooms in Burlington House into De Morgan House (named after t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

A Treatise On The Mathematical Theory Of Elasticity
A, or a, is the first letter and the first vowel letter of the Latin alphabet, used in the modern English alphabet, and others worldwide. Its name in English is '' a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version is often written in one of two forms: the double-storey and single-storey . The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English, '' a'' is the indefinite article, with the alternative form ''an''. Name In English, the name of the letter is the ''long A'' sound, pronounced . Its name in most other languages matches the letter's pronunciation in open syllables. History The earliest known ancestor of A is ''aleph''—the first letter of the Phoenician ...

Queen's College, Oxford
The Queen's College is a constituent college of the University of Oxford, England. The college was founded in 1341 by Robert de Eglesfield in honour of Philippa of Hainault, queen of England. It is distinguished by its predominantly neoclassical architecture, primarily dating from the 18th century. , the college had an endowment of £327.8 million making it the fifth-wealthiest Oxford college (after Christ Church, Magdalen, St. John's, and All Souls). History The college was founded in 1341 as "Hall of the Queen's scholars of Oxford" by Robert de Eglesfield (d'Eglesfield), chaplain to the then queen consort Philippa of Hainault, after whom the hall was named. Robert's aim was to provide clergymen for his native Cumberland and where he lived in Westmorland (both part of modern Cumbria). In addition, the college was to provide charity for the poor. The college's coat of arms is that of the founder; it differs slightly from his family's coat of arms, which did not inclu ...

Sedleian Professor Of Natural Philosophy
The Sedleian Professor of Natural Philosophy is the name of a chair at the Mathematical Institute of the University of Oxford. Overview The Sedleian Chair was founded by Sir William Sedley who, by his will dated 20 October 1618, left the sum of £2,000 to the University of Oxford for purchase of lands for its endowment. Sedley's bequest took effect in 1621 with the purchase of an estate at Waddesdon in Buckinghamshire to produce the necessary income. It is regarded as the oldest of Oxford's scientific chairs. Holders of the Sedleian Professorship have, since the mid 19th century, worked in a range of areas of applied mathematics and mathematical physics. They are simultaneously elected to fellowships at Queen's College, Oxford. The Sedleian Professors in the past century have been Augustus Love (1899-1940), who was distinguished for his work in the mathematical theory of elasticity, Sydney Chapman (1946-1953), who is renowned for his contributions to the kinetic theory o ...

Second Wrangler
At the University of Cambridge in England, a "Wrangler" is a student who gains first-class honours in the Mathematical Tripos competition. The highest-scoring student is the Senior Wrangler, the second highest is the Second Wrangler, and so on. By contrast, the person who achieves the lowest exam marks while still earning a third-class honours degree (that is, while still earning an honours degree at all) is known as the wooden spoon. History Until 1909, the university made the rankings public. Since 1910, it has publicly revealed only the class of degree gained by each student. An examiner reveals the identity of the Senior Wrangler "unofficially" by tipping his hat when reading out the person's name, but other rankings are communicated to each student privately. Therefore, the names of only some 20th-century Senior Wranglers (such as Crispin Nash-Williams, Christopher Budd, Frank P. Ramsey, Donald Coxeter, Kevin Buzzard, Jayant Narlikar, George Reid and Ben J. Green) h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
