Beryl May Dent
Beryl May Dent (10 May 19009 August 1977) was an English mathematical physicist, technical librarian, and a programmer of early analogue and digital computers to solve electrical engineering problems. She was born in Chippenham, Wiltshire, the eldest daughter of schoolteachers. The family left Chippenham in 1901, after her father became head teacher of the then recently established Warminster County School. In 1923, she graduated from the University of Bristol with First Class Honours in applied mathematics. She was awarded the Ashworth Hallett scholarship by the university and was accepted as a postgraduate student at Newnham College, University of Cambridge. She returned to Bristol in 1925, after being appointed a researcher in the Physics Department at the University of Bristol, with her salary being paid by the Department of Scientific and Industrial Research. In 1927, John Lennard-Jones was appointed Professor of Theoretical physics, a chair being created for him, with De ...

Chippenham
Chippenham is a market town in northwest Wiltshire, England. It lies northeast of Bath, west of London, and is near the Cotswolds Area of Natural Beauty. The town was established on a crossing of the River Avon and some form of settlement is believed to have existed there since before Roman times. It was a royal vill, and probably a royal hunting lodge, under Alfred the Great. The town continued to grow when the Great Western Railway arrived in 1841. The town had a population of 36,548 in 2021. Geography Location Chippenham is in western Wiltshire, at a prominent crossing of the River Avon, between the Marlborough Downs to the east, the southern Cotswolds to the north and west and Salisbury Plain to the southeast. The town is surrounded by sparsely populated countryside and there are several woodlands in or very near the town, such as Bird's Marsh, Vincients Wood and Briars Wood. Suburbs Suburbs include Cepen Park (North & South), Hardenhuish, Monkton, Lowden, Pewsh ...

Lilias Ashworth Hallett
Lilias Ashworth Hallett (1844 – 1922) was a leading British suffragist. She organised, helped to fund activities and was a speaker. She was said to have been "made ill" by the militants but she conceded that it was the militants that created the progress that she had spent years failing to achieve. Life Ashworth was born in 1844 to Thomas and Sophia (born Bright) Ashworth. Her mother came from an influential Quaker family and her notable siblings included Margaret Bright Lucas Margaret Bright Lucas (14 July 1818 – 4 February 1890) was a British temperance activist and suffragist Suffrage, political franchise, or simply franchise, is the right to vote in public, political elections and referendums (although th ..., John Bright , Jacob Bright and Priscilla Bright McLaren. Ashworth was rich and had an income from her father's estate. At the time men had to have property to qualify for a vote. Ashworth joked that her property should enable her to have seven votes. ...

Differential Analyser
The differential analyser is a mechanical analogue computer designed to solve differential equations by integration, using wheel-and-disc mechanisms to perform the integration. It was one of the first advanced computing devices to be used operationally. The original machines could not add, but then it was noticed that if the two wheels of a rear differential are turned, the drive shaft will compute the average of the left and right wheels. A simple gear ratio of 1:2 then enables multiplication by two, Multiplication is just a special case of integration, namely integrating a constant function. History Research on solutions for differential equations using mechanical devices, discounting planimeters, started at least as early as 1836, when the French physicist Gaspard-Gustave Coriolis designed a mechanical device to integrate differential equations of the first order. The first description of a device which could integrate differential equations of any order was published in ...

Differential Equation
In mathematics, a differential equation is an equation that relates one or more unknown functions and their derivatives. In applications, the functions generally represent physical quantities, the derivatives represent their rates of change, and the differential equation defines a relationship between the two. Such relations are common; therefore, differential equations play a prominent role in many disciplines including engineering, physics, economics, and biology. Mainly the study of differential equations consists of the study of their solutions (the set of functions that satisfy each equation), and of the properties of their solutions. Only the simplest differential equations are solvable by explicit formulas; however, many properties of solutions of a given differential equation may be determined without computing them exactly. Often when a closed-form expression for the solutions is not available, solutions may be approximated numerically using computers. The theory ...

Numerical Analysis
Numerical analysis is the study of algorithms that use numerical approximation (as opposed to symbolic manipulations) for the problems of mathematical analysis (as distinguished from discrete mathematics). It is the study of numerical methods that attempt at finding approximate solutions of problems rather than the exact ones. Numerical analysis finds application in all fields of engineering and the physical sciences, and in the 21st century also the life and social sciences, medicine, business and even the arts. Current growth in computing power has enabled the use of more complex numerical analysis, providing detailed and realistic mathematical models in science and engineering. Examples of numerical analysis include: ordinary differential equations as found in celestial mechanics (predicting the motions of planets, stars and galaxies), numerical linear algebra in data analysis, and stochastic differential equations and Markov chains for simulating living cells in medicine an ...

ASLIB
ASLIB: The Association for Information Management (often stylized ''Aslib'') was a British association of special libraries and information centres. It was founded in England in 1924 as the Association of Special Libraries and Information Bureaux. The organization ceased functioning as an independent organization in 2010, when it became a division of Emerald Group Publishing. Since 2015, ASLIB has existed only as Emerald's professional development arm. Wartime documentation ASLIB played a particular role in World War II obtaining journals and other documents from the Axis powers countries. Many countries around the world lost access to the documentation of academic and scientific information during wartime. UK libraries were often able to obtain these documents through neutral European countries. With Eugene Power, microfilming expert, and with funding from some US foundations such as the Rockefeller Foundation, ASLIB set up a large microfilming service that was able to supply key ...

Atomic Force Microscopy
Atomic force microscopy (AFM) or scanning force microscopy (SFM) is a very-high-resolution type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. Overview Atomic force microscopy (AFM) is a type of scanning probe microscopy (SPM), with demonstrated resolution on the order of fractions of a nanometer, more than 1000 times better than the optical diffraction limit. The information is gathered by "feeling" or "touching" the surface with a mechanical probe. Piezoelectric elements that facilitate tiny but accurate and precise movements on (electronic) command enable precise scanning. Despite the name, the Atomic Force Microscope does not use the Nuclear force. Abilities The AFM has three major abilities: force measurement, topographic imaging, and manipulation. In force measurement, AFMs can be used to measure the forces between the probe and the sample as ...

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concer ...

Department Of Scientific And Industrial Research (United Kingdom)
The Department of Scientific and Industrial Research was a department of the British Government responsible for the organisation, development, and encouragement of scientific and industrial research. At the outbreak of the First World War "Britain found ... it was dangerously dependent on enemy industries". At the request of the Board of Trade, the Board of Education prepared a White Paper under the chairmanship of Sir William McCormick. The DSIR was set up to fill the roles that the White Paper specified: "to finance worthy research proposals, to award research fellowships and studentships n universities and to encourage the development of research associations in private industry and research facilities in university science departments. trapidly assumed a key role in coordinating government aid to university research. It maintained these roles until 1965. The annual budget during its first year, 1915, was £1,000,000. History Before the twentieth century, the government w ...

Bristol
Bristol () is a city, ceremonial county and unitary authority in England. Situated on the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. Bristol is the most populous city in South West England. The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom. Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. A major port, Bristol was a starting place for early voyages of exploration to the New World. On a ship out of Bristol in 1497, John Cabot, a ...

Applied Mathematics
Applied mathematics is the application of mathematical methods by different fields such as physics, engineering, medicine, biology, finance, business, computer science, and industry. Thus, applied mathematics is a combination of mathematical science and specialized knowledge. The term "applied mathematics" also describes the 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 applied analysis, most notably differential equations; approximation theory (broadly construed, to include representations, asymptotic methods, variation ...

British Undergraduate Degree Classification
The British undergraduate degree classification system is a grading structure for undergraduate degrees or bachelor's degrees and integrated master's degrees in the United Kingdom. The system has been applied (sometimes with significant variations) in other countries and regions. History The classification system as currently used in the United Kingdom was developed in 1918. Honours were then a means to recognise individuals who demonstrated depth of knowledge or originality, as opposed to relative achievement in examination conditions. Concern exists about possible grade inflation. It is claimed that academics are under increasing pressure from administrators to award students good marks and grades with little regard for those students' actual abilities, in order to maintain their league table rankings. The percentage of graduates who receive a First (First Class Honours) has grown from 7% in 1997 to 26% in 2017, with the rate of growth sharply accelerating toward the end ...
