Thomas Simpson Evans (1777–1818) was a British mathematician.
Evans, eldest son of the Rev. Lewis Evans (1755–1827), by his wife, Ann Norman, was baptised in August 1777. He was named after Thomas Simpson, the mathematician.
Lewis Evans (1755–1827) was a Welsh mathematician.
Thomas Simpson FRS was a British mathematician and inventor known for the eponymous Simpson's rule to approximate definite integrals. The attribution, as often in mathematics, can be debated: this rule had been found 100 years earlier by Johannes Kepler, and in German it is called Keplersche Fassregel.
In or about 1797 Evans appears to have taken charge of a private observatory at Blackheath belonging to William Larkins, formerly accountant-general to the East India Company in Bengal. After the death of Larkins, 24 April 1800, he was taken on as an assistant by Nevil Maskelyne at the Royal Observatory, Greenwich, but resigned the post in 1805.
Blackheath is an affluent district of south east London, England, within the Royal Borough of Greenwich and the London Borough of Lewisham. It is located east of Lewisham, and south of Greenwich. Blackheath is within the historic boundaries of Kent.
The East India Company (EIC), also known as the Honourable East India Company (HEIC) or the British East India Company and informally as John Company, Company Bahadur, or simply The Company, was an English and later British joint-stock company. It was formed to trade in the Indian Ocean region, initially with Mughal India and the East Indies, and later with Qing China. The company ended up seizing control over large parts of the Indian subcontinent, colonised parts of Southeast Asia, and colonised Hong Kong after a war with Qing China.
The Rev Dr Nevil Maskelyne DD FRS FRSE was the fifth British Astronomer Royal. He held the office from 1765 to 1811. He was the first person to scientifically measure the weight of the planet Earth.
In that year, or perhaps in 1803, Evans was appointed mathematical master under his father at the Royal Military Academy, Woolwich. Here he continued until 1810, when he accepted the mastership of the mathematical school at New Charlton, near Woolwich, which office he vacated in 1813 to become master of the mathematics at Christ's Hospital, London. His attainments won for him the degree of LL.D. (from what university is not known) and the fellowship of the Linnean Society.
The Royal Military Academy (RMA) at Woolwich, in south-east London, was a British Army military academy for the training of commissioned officers of the Royal Artillery and Royal Engineers. It later also trained officers of the Royal Corps of Signals and other technical corps. RMA Woolwich was commonly known as "The Shop" because its first building was a converted workshop of the Woolwich Arsenal.
Evans died 28 October 1818, aged 41.
Evans left a completed translation of Antonio Cagnoli's ‘Trigonometria piana e sferica,’ besides other translations of scientific works and a collection of unfinished papers in several branches of philosophy. He also contributed some articles to the Philosophical Magazine , among which were:
Antonio Cagnoli was an Italian astronomer, mathematician and diplomat in the service of the Republic of Venice. His father Ottavio was chancellor to the Venetian governor of the Ionian Islands.
The Philosophical Magazine is one of the oldest scientific journals published in English. It was established by Alexander Tilloch in 1798; in 1822 Richard Taylor became joint editor and it has been published continuously by Taylor & Francis ever since.
Evans's library was considered a valuable collection of mathematical and philosophical works.
By his marriage in 1797 to Deborah, daughter of John Mascall of Ashford, Kent, Evans had five children:
St Leonard's, Shoreditch is the ancient parish church of Shoreditch, often known simply as Shoreditch Church. It is located at the intersection of Shoreditch High Street with Hackney Road, within the London Borough of Hackney. The current building dates from about 1740. The church is mentioned in the line "When I grow rich, say the bells of Shoreditch" from the nursery rhyme Oranges and Lemons and is noted as being the resting place of many actors from the Tudor period.
William Nicholson was a renowned English chemist and writer on "natural philosophy" and chemistry, as well as a translator, journalist, publisher, scientist, inventor, patent agent and civil engineer.
Charles Hutton FRS FRSE LLD was an English mathematician and surveyor. He was professor of mathematics at the Royal Military Academy, Woolwich from 1773 to 1807. He is remembered for his calculation of the density of the earth from Nevil Maskelyne's measurements collected during the Schiehallion experiment.
William Rutherford (1798–1871) was an English mathematician famous for his calculation of 208 digits of the mathematical constant π in 1841.
Thomas Stephens Davies FRS FRSE(1795–1851) was a British mathematician.
Sir John Henry Pelly, 1st Baronet, DL was an English businessman. During most of his career, he was an employee of the Hudson's Bay Company (HBC), serving as Governor of the HBC for three decades. He held other noteworthy offices, including Governor of the Bank of England. The title of Baronet Pelly was created for him.
John Aikin (1713–1780) was an English Unitarian scholar and theological tutor, closely associated with Warrington Academy, a prominent dissenting academy.
George Walker was a versatile English Dissenter, known as a mathematician, theologian, Fellow of the Royal Society, and activist.
John Tipper (1663–1713) was an English mathematician and almanac-maker, now known as the founder of The Ladies' Diary, in which some important mathematical results were first published.
Patrick Kelly LL.D. (1756–1842) was a British metrologist, best known for his comparative studies of weights and measures collected in his works Universal Cambist (1811) and Oriental Metrology (1832). Kelly was Master of the Finsbury Square Academy, London. He was also instrumental in the establishment of the Imperial system of measurement through the Weights and Measures Act 1824.
William Mudge (1762–1820) was an English artillery officer and surveyor, born in Plymouth, an important figure in the work of the Ordnance Survey.
John Law DD (1745–1810) was an English mathematician and clergyman who began his career as a Fellow of Christ's College, Cambridge, and went on to become chaplain to the Lord Lieutenant of Ireland and Church of Ireland bishop of Clonfert and Kilmacduagh (1782–1787), Killala and Achonry (1787–1795), and finally of Elphin (1795–1810).
