John Cuthbertson (instrument Maker)
John Cuthbertson (bapt. 1 July 1743 in Dearham – 1821) was an English instrument maker and inventor that lived from 1768 until roughly 1796 in Amsterdam. Biography John was the second son of the inn keeper and yeoman Jonathan Cuthbertson and his second wife Mary Fisher. John had three siblings, of which two survived (a younger brother Jonathan (1744–1806) and one other): the third died at young age (Jonathan, the eldest). John and the younger brother Jonathan are often confused in literature and publications. While John worked for a long time in Amsterdam, Jonathan worked n Rotterdam, both in the same line of work. John studied with the prominent London instrument maker James Champneys and when Champney moved to Amsterdamaccording to some sources after a bankruptcy: other sources deny this (Bryden 1977) in December 1768 Cuthbertson joined him. On 1 September 1768 John had married Champney's daughter Jane. They had four children, three sons and a daughter, but only the daught ...

Electrostatic Generator Teylers Museum
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 ...

Teylers Museum
Teylers Museum () is an art, natural history, and science museum in Haarlem, Netherlands. Established in 1778, Teylers Museum was founded as a centre for contemporary art and science. The historic centre of the museum is the neoclassical Oval Room (1784), which was built behind the house of Pieter Teyler van der Hulst (1702–1778), the so-called ''Fundatiehuis'' (Foundation House). Pieter Teyler was a wealthy cloth merchant and banker of Scottish descent, who bequeathed his fortune for the advancement of religion, art, and science. He was a Mennonite and follower of the Scottish Enlightenment. History In his will, Pieter Teyler stipulated that his collection and part of his fortune should be used to establish a foundation for their promotion: Teylers Stichting. The Teyler legacy to the city of Haarlem was split into two societies: Teylers First or Theological Society (Dutch: ''Teylers Eerste of Godgeleerd Genootschap''), intended for the study of religion and Teylers Second ...

St James's Church, Piccadilly
St James's Church, Piccadilly, also known as St James's Church, Westminster, and St James-in-the-Fields, is an Anglican church on Piccadilly in the centre of London, United Kingdom. The church was designed and built by Sir Christopher Wren. The church is built of red brick with Portland stone dressings. Its interior has galleries on three sides supported by square pillars and the nave has a barrel vault supported by Corinthian columns. The carved marble font and limewood reredos are both notable examples of the work of Grinling Gibbons. In 1902, an outside pulpit was erected on the north wall of the church. It was designed by Temple Moore and carved by Laurence Arthur Turner. It was damaged in 1940, but restored at the same time as the rest of the fabric. History In 1662, Henry Jermyn, 1st Earl of St Albans, was granted land for residential development on what was then the outskirts of London. He set aside land for the building of a parish church and churchyard on the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rees's Cyclopædia
Rees's ''Cyclopædia'', in full ''The Cyclopædia; or, Universal Dictionary of Arts, Sciences, and Literature'' was an important 19th-century British encyclopaedia edited by Rev. Abraham Rees (1743–1825), a Presbyterian minister and scholar who had edited previous editions of '' Chambers's Cyclopædia''. Background When Rees was planning his ''Cyclopædia'', Europe was in the aftermath of the French Revolution, and during serialised publication (1802–1820) the Napoleonic Wars and War of 1812 occurred. Britain absorbed into its empire a number of the former French and Dutch colonies around the world; Romanticism came to the fore; evangelical Christianity flourished with the efforts of William Wilberforce; and factory manufacture burgeoned. With this background, philosophical radicalism was suspect in Britain, and aspects of the ''Cyclopædia'' were thought to be distinctly subversive and attracted the hostility of the Loyalist press.

Electrometer
An electrometer is an electrical instrument for measuring electric charge or electrical potential difference. There are many different types, ranging from historical handmade mechanical instruments to high-precision electronic devices. Modern electrometers based on vacuum tube or solid-state technology can be used to make voltage and charge measurements with very low leakage currents, down to 1 femtoampere. A simpler but related instrument, the electroscope, works on similar principles but only indicates the relative magnitudes of voltages or charges. Historical electrometers Gold-leaf electroscope The gold-leaf electroscope was one of the instruments used to indicate electric charge. It is still used for science demonstrations but has been superseded in most applications by electronic measuring instruments. The instrument consists of two thin leaves of gold foil suspended from an electrode. When the electrode is charged by induction or by contact, the leaves acquire simi ...

Dearham
Dearham is a village and civil parish in the Allerdale district of Cumbria, historically part of Cumberland, near the Lake District National Park in England. It lies about east of Maryport and west of Cockermouth. According to the 2001 census it had a population of 2,028, increasing to 2,151 at the 2011 Census. Etymology 'Dearham' is an Old Anglian compound of 'dēor' and 'hām'. Old Anglian is Old English. 'Dēor' means 'deer', 'hām' is 'homestead' or 'village' or 'estate'. History With its resources of coal and easy access to railways, Dearham is part of Cumberland's former coal mining industry. It saw its population increase from 515 in 1821 to 2,598 in 1891 due to the expansion of coal mining. However, with the decline of deep mining and, later, open cast working, the coal industry ceased to be a source of employment in the area. Historically, Dearham was in the Workington division of the County of Cumberland, in the ward of Allerdale below Derwent. It belonged to the ...

Volt
The volt (symbol: V) is the unit of electric potential, electric potential difference (voltage), and electromotive force in the International System of Units (SI). It is named after the Italian physicist Alessandro Volta (1745–1827). Definition One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. Equivalently, it is the potential difference between two points that will impart one joule of energy per coulomb of charge that passes through it. It can be expressed in terms of SI base units ( m, kg, second, s, and ampere, A) as : \text = \frac = \frac = \frac. It can also be expressed as amperes times ohms (current times resistance, Ohm's law), webers per second (magnetic flux per time), watts per ampere (power per current), or joules per coulomb (energy per charge), which is also equivalent to electronvolts per elementary charge: : \text = \tex ...
