Timothy Priestley
Timothy Priestley (19 June 1734 – 23 April 1814) was an English Independent minister. The younger brother of Joseph Priestley, he was a collaborator in making electrical apparatus. Life The second child of Jonas and Mary Priestley, was born at Fieldhead in the parish of Birstall, West Yorkshire, Birstall, Yorkshire, on 19 June 1734. He was brought up by his grandfather, Joseph Swift, and sent to school at Batley. For some time he was employed in his father's business as a cloth-dresser. His elder brother Joseph Priestley, thought Timothy frivolous; but he received a religious direction from James Scott (1710-1783), who became minister of Upper Chapel, Heckmondwike in Yorkshire, in 1754. Scott in 1756 established a dissenting academy at Southfield, near Heckmondwike, and Timothy Priestley was the second young man who entered it as a student for the ministry. He got into trouble, however, by going out to preach without leave; and Joseph disparaged his training. Timothy Priestley' ...

Joseph Priestley
Joseph Priestley (; 24 March 1733 – 6 February 1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, and liberal political theorist. He published over 150 works, and conducted experiments in electricity and other areas of science. He was a close friend of, and worked in close association with Benjamin Franklin involving electricity experiments. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. Prie ...

Moorfields
Moorfields was an open space, partly in the City of London, lying adjacent to – and outside – its northern wall, near the eponymous Moorgate. It was known for its marshy conditions, the result of the defensive wall acting like a dam, impeding the flow of the River Walbrook and its tributaries. Moorfields gives its name to the Moorfields Eye Hospital which occupied a site on the former fields from 1822–1899, and is still based close by, in the St Luke's area of the London Borough of Islington. Setting Moorfields is first recorded in the late 12th century, though not by name, as a ''great fen''. The fen was larger than the area subsequently known as Moorfields. Moorfields was contiguous with Finsbury Fields, Bunhill Fields and other open spaces, and until its eventual loss in the 19th century, was the innermost part of a green wedge of land which stretched from the wall, to the open countryside which lay close by. Moorfields separated the western and eastern growth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Familiar Introduction To Electricity By Joseph Priestly, Plate 7
In European folklore of the medieval and early modern periods, familiars (sometimes referred to as familiar spirits) were believed to be supernatural entities that would assist witches and cunning folk in their practice of magic. According to records of the time, those alleging to have had contact with familiar spirits reported that they could manifest as numerous forms, usually as an animal, but sometimes as a human or humanoid figure, and were described as "clearly defined, three-dimensional... forms, vivid with colour and animated with movement and sound", as opposed to descriptions of ghosts with their "smoky, undefined form . When they served witches, they were often thought to be malevolent, but when working for cunning folk they were often considered benevolent (although there was some ambiguity in both cases). The former were often categorized as demons, while the latter were more commonly thought of and described as fairies. The main purpose of familiars was to serve the ...

Lathe
A lathe () is a machine tool that rotates a workpiece about an axis of rotation to perform various operations such as cutting, sanding, knurling, drilling, deformation, facing, and turning, with tools that are applied to the workpiece to create an object with symmetry about that axis. Lathes are used in woodturning, metalworking, metal spinning, thermal spraying, parts reclamation, and glass-working. Lathes can be used to shape pottery, the best-known design being the Potter's wheel. Most suitably equipped metalworking lathes can also be used to produce most solids of revolution, plane surfaces and screw threads or helices. Ornamental lathes can produce three-dimensional solids of incredible complexity. The workpiece is usually held in place by either one or two ''centers'', at least one of which can typically be moved horizontally to accommodate varying workpiece lengths. Other work-holding methods include clamping the work about the axis of rotation using a chuck or col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrostatics
Electrostatics is a branch of physics that studies electric charges at rest (static electricity). Since classical times, it has been known that some materials, such as amber, attract lightweight particles after rubbing. The Greek word for amber, (), was thus the source of the word 'electricity'. Electrostatic phenomena arise from the forces that electric charges exert on each other. Such forces are described by Coulomb's law. Even though electrostatically induced forces seem to be rather weak, some electrostatic forces are relatively large. The force between an electron and a proton, which together make up a hydrogen atom, is about 36 orders of magnitude stronger than the gravitational force acting between them. There are many examples of electrostatic phenomena, from those as simple as the attraction of plastic wrap to one's hand after it is removed from a package, to the apparently spontaneous explosion of grain silos, the damage of electronic components during manufacturin ...

John Barrow (geographical Compiler)
John Barrow (fl. 1735–1774) was an English mathematician, naval historian and lexicographer. His geographical dictionary first appeared in 1756. Life Nothing is known of Barrow's family. He was initially a teacher of mathematics and navigation aboard ships of the Royal Navy. He retired before 1750 and devoted himself to writing and compiling dictionaries and other works related to his knowledge of mathematics and science. Barrow's best-known work was ''Navigatio Britannica'' (1750), a practical handbook of navigation and charts still being advertised by its publisher, Mount & Page, in 1787. It included an examination of nautical instruments and explained the recently introduced vernier scale. Barrow seems to have been in close touch with nautical instrument makers while he was a naval instructor. It was not realized until the 20th century that John Barrow the "geographical compiler" mentioned in the British ''Dictionary of National Biography'' (1885 onwards) and the teacher o ...

Daventry Academy
Daventry Academy was a dissenting academy, that is, a school or college set up by English Dissenters. It moved to many locations, but was most associated with Daventry, where its most famous pupil was Joseph Priestley. It had a high reputation, and in time it was amalgamated into New College London. History An academy was started in Kibworth around 1715, and moved at some point to Market Harborough, where Philip Doddridge was chosen as its principal. The academy moved to Northampton in 1729. The academy attracted the support of the Coward Trust, funded through the philanthropy of William Coward (died 1738), a London merchant who used his money to train ministers for the " protestant dissenters". After the death of Doddridge in 1751, the trustees took over the academy. In 1752 the academy was moved to Daventry, back to Northampton, then to Wymondley, and finally in 1833 to London. Northampton While known as the Northampton Academy, several notable English Unitarian ministers wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Canton
John Canton FRS (31 July 1718 – 22 March 1772) was a British physicist. He was born in Middle Street Stroud, Gloucestershire, to a weaver, John Canton (b. 1687) and Esther (née Davis). As a schoolboy, he became the first person to determine the latitude of Stroud, whilst making a sundial. The sundial caught the attention of many, including Dr Henry Miles, a Stroud-born Fellow of the Royal Society. Miles encouraged Canton to leave Gloucestershire to become a trainee teacher for Samuel Watkins, the headmaster of a Nonconformist school in Spital Square, London, with whom he ultimately entered into partnership. In 1750 he read a paper before the Royal Society on a method of making artificial magnets, and was subsequently elected a Fellow of the society (FRS). In 1751 he was a recipient of the Copley Medal "On account of his communicating to the Society, and exhibiting before them, his curious method of making Artificial Magnets without the use of Natural ones." He was the fir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electrical Kite
The kite experiment is a scientific experiment in which a kite with a pointed, conductive wire attached to its apex is flown near thunder clouds to collect electricity from the air and conduct it down the wet kite string to the ground. It was proposed and may have been conducted by Benjamin Franklin with the assistance of his son William Franklin. The experiment's purpose was to uncover the unknown facts about the nature of lightning and electricity, and with further experiments on the ground, to demonstrate that lightning and electricity were the result of the same phenomenon. Background Speculations of Jean-Antoine Nollet had led to the issue of the electrical nature of lightning being posed as a prize question at Bordeaux in 1749. In 1750, it was the subject of public discussion in France, with a dissertation of Denis Barberet receiving a prize in Bordeaux; Barberet proposed a cause in line with the triboelectric effect. The same year, Franklin reversed his previous skeptici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Burder
George Burder (May 25, 1752 O.S.May 29, 1832) was an English Nonconformist divine. Biography Burder was born in London. In his early twenties he was an engraver, but in 1776 he began preaching, and was minister of the Independent church at Lancaster from 1778 to 1783. Subsequently he held charges at Coventry (1784–1803) and at Fetter Lane, London (1803–1832). He was one of the founders of the British and Foreign Bible Society, the Religious Tract Society, and the London Missionary Society, and was secretary to the last-named for several years. As editor of the '' Evangelical Magazine'' and author of ''Village Sermons'' (translated into several European languages), he commanded a wide influence. He died on 29 May 1832, and the following year ''A Life'' (by Henry Forster Burder) was published. One of his grandsons, George Bernard Burder (18141881) converted to Roman Catholicism and became Abbot of Mount St Bernard Abbey Mount St Bernard Abbey is a Roman Catholic, Tra ...

Bunhill Fields
Bunhill Fields is a former burial ground in central London, in the London Borough of Islington, just north of the City of London. What remains is about in extent and the bulk of the site is a public garden maintained by the City of London Corporation. It was first in devoted use as a burial ground from 1665 until 1854, in which period approximately 123,000 interments were estimated to have taken place. Over 2,000 monuments remain, for the most part in concentrated blocks. It was a prototype of land-use protected, nondenominational grounds, and was particularly favoured by Nonconformist (Protestantism), nonconformists who passed their final years in the region. It contains the graves of many notable people, including John Bunyan (died 1688), author of ''The Pilgrim's Progress''; Daniel Defoe (died 1731), author of ''Robinson Crusoe''; William Blake (died 1827), artist, poet, and mystic; Susanna Wesley (died 1742), known as the "Mother of Methodism" through her education of sons ...

Islington
Islington () is a district in the north of Greater London, England, and part of the London Borough of Islington. It is a mainly residential district of Inner London, extending from Islington's High Street to Highbury Fields, encompassing the area around the busy High Street, Upper Street, Essex Road (former "Lower Street"), and Southgate Road to the east. Modern definition Islington grew as a sprawling Middlesex village along the line of the Great North Road, and has provided the name of the modern borough. This gave rise to some confusion, as neighbouring districts may also be said to be in Islington. This district is bounded by Liverpool Road to the west and City Road and Southgate Road to the south-east. Its northernmost point is in the area of Canonbury. The main north–south high street, Upper Street splits at Highbury Corner to Holloway Road to the west and St. Paul's Road to the east.
