Peter Ewart
Peter Ewart (14 May 1767 – 15 September 1842) was a British engineer who was influential in developing the technologies of turbines and theories of thermodynamics. Biography He was son of the Church of Scotland minister of Troqueer near Dumfries, and was one of eleven children. His brother Joseph Ewart became British ambassador to Prussia; John, a doctor, became Chief Inspector of East India Company hospitals in India; and William, father of William Ewart, was business partner of Sir John Gladstone, father of William Ewart Gladstone, whose godfather he was and whom he was named after. Following graduation from the University of Edinburgh, he was apprenticed to millwright John Rennie. His work with water wheels led him to work with Matthew Boulton and James Watt for whom by 1790 he was agent in Manchester. At the same time as acting as agent he was also trading on his own account as a millwright, enabling him to provide the complementary shafts, gears and other necessit ...

Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Partnership
A partnership is an arrangement where parties, known as business partners, agree to cooperate to advance their mutual interests. The partners in a partnership may be individuals, businesses, interest-based organizations, schools, governments or combinations. Organizations may partner to increase the likelihood of each achieving their mission and to amplify their reach. A partnership may result in issuing and holding equity or may be only governed by a contract. History Partnerships have a long history; they were already in use in medieval times in Europe and in the Middle East. According to a 2006 article, the first partnership was implemented in 1383 by Francesco di Marco Datini, a merchant of Prato and Florence. The Covoni company (1336-40) and the Del Buono-Bencivenni company (1336-40) have also been referred to as early partnerships, but they were not formal partnerships. In Europe, the partnerships contributed to the Commercial Revolution which started in the 13th ce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heat
In thermodynamics, heat is defined as the form of energy crossing the boundary of a thermodynamic system by virtue of a temperature difference across the boundary. A thermodynamic system does not ''contain'' heat. Nevertheless, the term is also often used to refer to the thermal energy contained in a system as a component of its internal energy and that is reflected in the temperature of the system. For both uses of the term, heat is a form of energy. An example of formal vs. informal usage may be obtained from the right-hand photo, in which the metal bar is "conducting heat" from its hot end to its cold end, but if the metal bar is considered a thermodynamic system, then the energy flowing within the metal bar is called internal energy, not heat. The hot metal bar is also transferring heat to its surroundings, a correct statement for both the strict and loose meanings of ''heat''. Another example of informal usage is the term '' heat content'', used despite the fact tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Dalton
John Dalton (; 5 or 6 September 1766 – 27 July 1844) was an English chemist, physicist and meteorologist. He is best known for introducing the atomic theory into chemistry, and for his research into colour blindness, which he had. Colour blindness is known as ''Daltonism'' in several languages, being named after him. Early life John Dalton was born into a Quaker family in Eaglesfield, near Cockermouth, in Cumberland, England. His father was a weaver. He received his early education from his father and from Quaker John Fletcher, who ran a private school in the nearby village of Pardshaw Hall. Dalton's family was too poor to support him for long and he began to earn his living, from the age of ten, in the service of wealthy local Quaker Elihu Robinson. Early career When he was 15, Dalton joined his older brother Jonathan in running a Quaker school in Kendal, Westmorland, about from his home. Around the age of 23, Dalton may have considered studying law or medi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watt Steam Engine
The Watt steam engine design became synonymous with steam engines, and it was many years before significantly new designs began to replace the basic Watt design. The first steam engines, introduced by Thomas Newcomen in 1712, were of the "atmospheric" design. At the end of the power stroke, the weight of the object being moved by the engine pulled the piston to the top of the cylinder as steam was introduced. Then the cylinder was cooled by a spray of water, which caused the steam to condense, forming a partial vacuum in the cylinder. Atmospheric pressure on the top of the piston pushed it down, lifting the work object. James Watt noticed that it required significant amounts of heat to warm the cylinder back up to the point where steam could enter the cylinder without immediately condensing. When the cylinder was warm enough that it became filled with steam the next power stroke could commence. Watt realised that the heat needed to warm the cylinder could be saved by addin ...

River Bollin
The River Bollin is a major tributary of the River Mersey in the north-west of England. It rises in Macclesfield Forest at the western end of the Peak District, and can be seen in spring form, from the Buxton to Macclesfield road. The stream then descends the through Macclesfield and The Carrs Park in Wilmslow where it has a confluence with the River Dean, near to Styal Prison. For the following it defines the southwestern portion of the border between Greater Manchester and Cheshire before merging with the River Mersey north of Lymm. It flows through the Styal country park and was used in the cotton calico factory there, Quarry Bank Mill, as a source of power. Near to the Quarry Bank Mill site there is a natural weir. The Bollin is culverted underneath the southern runway of Manchester Airport. The town of Macclesfield Macclesfield is a market town and civil parish in the unitary authority of Cheshire East in Cheshire, England. It is located on the River Bollin i ...

Quarry Bank Mill
Quarry Bank Mill (also known as Styal Mill) in Styal, Cheshire, England, is one of the best preserved textile factories of the Industrial Revolution. Built in 1784, the cotton mill is recorded in the National Heritage List for England as a designated Grade II* listed building. Quarry Bank Mill was established by Samuel Greg, and was notable for innovations both in machinery and also in its approach to labour relations, the latter largely as a result of the work of Greg's wife, Hannah Lightbody. The family took a somewhat paternalistic attitude toward the workers, providing medical care for all and limited education to the children, but all laboured roughly 72 hours per week until 1847 when a new law shortened the hours. Greg also built housing for his workers, in a large community now known as Styal Estate. Some were conversions of farm houses, or older residences but 42 new cottages, including the Oak Cottages (now Grade II Listed), were built in the 1820s when the mi ...

Samuel Greg
Samuel Greg (26 March 1758 – 4 June 1834) was an Irish-born industrialist and entrepreneur of the early Industrial Revolution and a pioneer of the factory system. He built Quarry Bank Mill, which at his retirement was the largest textile mill in the country. He and his wife Hannah Greg assumed welfare responsibilities for their employees, many of whom were children, building a model village alongside the factory. At the same time, Greg inherited and operated a slave plantation in the West Indies. Atlantic-trading Belfast family Greg was born in Belfast, Ireland, the second son, and one of thirteen children, born to Elizabeth (Hyde) (1721-1780) and Thomas Greg of Belfast (1718 – 1796). With his business partner and brother-in-law, Waddell Cunningham, Thomas Greg commanded one of the greatest mercantile fortunes in Ireland. The son of a Scottish blacksmith, in the 1740s Thomas Greg bought a small ship which carried salted provisions, linen and butter to the West Indies and ...

Printing
Printing is a process for mass reproducing text and images using a master form or template. The earliest non-paper products involving printing include cylinder seals and objects such as the Cyrus Cylinder and the Cylinders of Nabonidus. The earliest known form of printing as applied to paper was woodblock printing, which appeared in China before 220 AD for cloth printing. However, it would not be applied to paper until the seventh century.Shelagh Vainker in Anne Farrer (ed), "Caves of the Thousand Buddhas", 1990, British Museum publications, Later developments in printing technology include the movable type invented by Bi Sheng around 1040 AD and the printing press invented by Johannes Gutenberg in the 15th century. The technology of printing played a key role in the development of the Renaissance and the Scientific Revolution and laid the material basis for the modern knowledge-based economy and the spread of learning to the masses.

Calico (textile)
Calico (; in British usage since 1505) is a heavy plain-woven textile made from unbleached, and often not fully processed, cotton. It may also contain unseparated husk parts. The fabric is far coarser than muslin, but less coarse and thick than canvas or denim. However, it is still very cheap owing to its unfinished and undyed appearance. The fabric was originally from the city of Calicut in southwestern India. It was made by the traditional weavers called cāliyans. The raw fabric was dyed and printed in bright hues, and calico prints became popular in Europe. History Origins Calico originated in Calicut, from which the name of the textile came, in South India, now Kerala, during the 11th century, where the cloth was known as "chaliyan". It was mentioned in Indian literature by the 12th century when the polymath and writer Hemachandra described calico fabric prints with a lotus design.''Encyclopædia Britannica'' (2008)"calico" Calico was woven using Gujarati cotton from Su ...
