C. Brian Haselgrove
Colin Brian Haselgrove (26 September 1926 – 27 May 1964) was an England, English mathematician who is best known for his disproof of the Pólya conjecture in 1958. Haselgrove was educated at Blundell's School and from there won a scholarship to King's College, Cambridge. He obtained his Ph.D., which was supervised by Albert Ingham, from Cambridge in 1956. Personal life Haselgrove was married to fellow mathematician Jenifer Haselgrove. After having suffered minor epileptic fits for several years caused by a brain tumor, he died in Manchester in May 1964. References External links * {{DEFAULTSORT:Haselgrove, C.

London Borough Of Waltham Forest
The London Borough of Waltham Forest () is a London borough in north-east London, England. Its population is estimated to be 276,983 in 2019. It borders five other London boroughs: Enfield to the north-west, Haringey to the west, Hackney to the south-west, Newham to the south-east and Redbridge to the east, as well as the non-metropolitan county of Essex to the north. The borough was formed in 1965 from the merger of the municipal boroughs of Leyton, Walthamstow and Chingford; it took its name from Waltham Forest – an institution which managed deer in south-west Essex. Epping Forest is a remainder of the former Waltham Forest and forms the eastern and northern fringe of the borough. The River Lea lies to the west where its associated marshes and parkland form a green corridor which, along the reservoir-lined reaches, separates north and east London, and is the historic border between Middlesex and Essex. Waltham Forest was one of the host boroughs of the London Olympics i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
King's College, Cambridge
King's College is a constituent college of the University of Cambridge. Formally The King's College of Our Lady and Saint Nicholas in Cambridge, the college lies beside the River Cam and faces out onto King's Parade in the centre of the city. King's was founded in 1441 by King Henry VI soon after he had founded its sister institution at Eton College. Initially, King's accepted only students from Eton College. However, the king's plans for King's College were disrupted by the Wars of the Roses and the resultant scarcity of funds, and then his eventual deposition. Little progress was made on the project until 1508, when King Henry VII began to take an interest in the college, probably as a political move to legitimise his new position. The building of the college's chapel, begun in 1446, was finished in 1544 during the reign of Henry VIII. King's College Chapel is regarded as one of the finest examples of late English Gothic architecture. It has the world's largest fan vaul ...

Number Theorists
Number theory (or arithmetic or higher arithmetic in older usage) is a branch of pure mathematics devoted primarily to the study of the integers and integer-valued functions. German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."German original: "Die Mathematik ist die Königin der Wissenschaften, und die Arithmetik ist die Königin der Mathematik." Number theorists study prime numbers as well as the properties of mathematical objects made out of integers (for example, rational numbers) or defined as generalizations of the integers (for example, algebraic integers). Integers can be considered either in themselves or as solutions to equations (Diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (for example, the Riemann zeta function) that encode properties of the integers, primes or other number-theoretic objects in ...

People Educated At Blundell's School
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Jenifer Haselgrove
Jenifer Leech (née Wheildon Brown; later Haselgrove; 3 August 1930 – 13 March 2015) was a British physicist and computer scientist. She is most noted for her formulation of ray tracing equations in a cold magneto-plasma, now widely known in the radio science community as Haselgrove's Equations.J. M. Kelso : "Radio ray propagation in the ionosphere", McGraw-Hill, 1964, 408 pp Haselgrove's equations Haselgrove developed her equations at Cambridge University in the 1950s, as a student under Kenneth Budden, by re-applying the earlier work of William Rowan Hamilton and Hamilton's principle in geometrical optics to radio propagation in a plasma. Indeed, the application of Haselgrove's equations is often termed Hamiltonian ray tracing. Ray tracing is intrinsically an approximation that is often called geometric. It formulates as the Eikonal equation and is only applicable under certain conditions including that the plasma is slowly varying; nevertheless it has enormous practical use ...

Blundell's School
Blundell's School is a co-educational day and boarding independent school in the English public school tradition, located in Tiverton, Devon. It was founded in 1604 under the will of Peter Blundell, one of the richest men in England at the time, and moved to its present site on the outskirts of the town in 1882. While the full boarding fees are £38,985 per year, the school offers several scholarships and bursaries, and provides flexi-boarding. The school has 360 boys and 225 girls, including 117 boys and 85 girls in the Sixth Form, and is a member of the Headmasters' and Headmistresses' Conference. The ''Good Schools Guide'' calls Blundell's a "distinguished rural school of ancient lineage". History Peter Blundell, one of the wealthiest merchants of Elizabethan England, died in 1601, having made his fortune principally in the cloth industry. His will set aside considerable money and land to establish a school in his home town "to maintain sound learning and true religion". ...

Disproof
A proof is sufficient evidence or a sufficient argument for the truth of a proposition. The concept applies in a variety of disciplines, with both the nature of the evidence or justification and the criteria for sufficiency being area-dependent. In the area of oral and written communication such as conversation, dialog, rhetoric, etc., a proof is a persuasive perlocutionary speech act, which demonstrates the truth of a proposition. In any area of mathematics defined by its assumptions or axioms, a proof is an argument establishing a theorem of that area via accepted rules of inference starting from those axioms and from other previously established theorems. The subject of logic, in particular proof theory, formalizes and studies the notion of formal proof. In some areas of epistemology and theology, the notion of justification plays approximately the role of proof, while in jurisprudence the corresponding term is evidence, with "burden of proof" as a concept common to both ph ...
