River Don, Yorkshire
–
The River Don is a river in South Yorkshire, England. It rises in the Pennines and flows for 70 miles eastwards, through the Don Valley, via Penistone, Sheffield, Rotherham, Mexborough, Conisbrough, Doncaster and Stainforth. It originally joined the Trent, but was re-engineered by Cornelius Vermuyden as the Dutch River in the 1620s, Don Valley is the local UK parliamentary constituency near the Doncaster stretch of the river. The Don can be divided into sections by the different types of structures built to restrict its passage, the upper reaches, and those of several of its tributaries, are defined by dams built to provide a public water supply. The Dons major tributaries are the Loxley, the Rivelin, the Sheaf, the Rother, along the Sheffield–Rotherham stretch of the river are five weirs that punctuate a local walking and cycling route, the Five Weirs Walk. A further walk, the Upper Don Walk, is being developed that make it possible to walk or cycle from Sheffield city centre up to Oughtibridge. The Don derives its name from Dôn, a Celtic mother goddess, the river gave its name to the Don River, one of the principal rivers of Toronto, Canada. Below Doncaster, the channel of the lower Don originally meandered in a north-easterly direction across the marshland of Hatfield Chase to enter the Trent just above its junction with the Ouse. A second channel flowed to the north, along a Roman channel called Turnbridgedike, the eastern channel formed the boundary between Yorkshire and Lincolnshire. In the Hatfield Level drainage project which started in 1626, the Dutch civil engineer Cornelius Vermuyden diverted the Don northwards along Turnbridgedike and he constructed Dikesmarsh bank some distance to the east of the channel, so that the intervening land could be used as washlands. Water levels here were between 5 and 10 feet lower than at Turnbridge and this new channel was called the Dutch River, and was finished in 1635, at a cost of £33,000. It ended in a sluice at Goole, and was never intended to be navigable, the sluice was later swept away in a flood and never replaced. The Dutch River was difficult to navigate, made more hazardous by shoals and they acquired the waterways in 1895, but failed to raise sufficient capital for the major improvements they had planned. However, they succeeded in constructing the New Junction Canal from Stainforth to the Aire and Calder Navigation west of Goole, which was funded by the Aire and Calder. The Dutch River reverted almost entirely to its drainage function, and Stainforth lock. The river was navigable to Rotherham in 1740, and to Tinsley by 1751, Stainforth was connected to the River Trent by the opening on the Stainforth and Keadby Canal in 1802 and to the Aire and Calder Navigation by the New Junction Canal, opened in 1905. The navigation was the subject of one of the last major attempts in the UK to attract commercial freight to the waterways, in 1983, it was upgraded to the 700-tonne Eurobarge standard by deepening the channels and enlarging the locks as far as Rotherham. The expected rise in freight traffic did not occur, however, the cuts and navigable river sections, with the Stainforth and Keadby and the New Junction canals constitute the Sheffield and South Yorkshire Navigation

Sheffield
–
Sheffield is a city and metropolitan borough in South Yorkshire, England. Historically part of the West Riding of Yorkshire, its derives from the River Sheaf. With some of its southern suburbs annexed from Derbyshire, the city has grown from its industrial roots to encompass a wider economic base. The population of the City of Sheffield is 569,700, Sheffield is the third largest English district by population. The metropolitan population of Sheffield is 1,569,000, in the 19th century, Sheffield gained an international reputation for steel production. Known as the Steel City, many innovations were developed locally, including crucible and stainless steel, Sheffield received its municipal charter in 1843, becoming the City of Sheffield in 1893. International competition in iron and steel caused a decline in these industries in the 1970s and 1980s, the 21st century has seen extensive redevelopment in Sheffield along with other British cities. Sheffields gross value added has increased by 60% since 1997, standing at £9.2 billion in 2007, the economy has experienced steady growth averaging around 5% annually, greater than that of the broader region of Yorkshire and the Humber. The city is in the foothills of the Pennines, and the valleys of the River Don and its four tributaries, the Loxley, the Porter Brook, the Rivelin. 61% of Sheffields entire area is space, and a third of the city lies within the Peak District national park. The area now occupied by the City of Sheffield is believed to have inhabited since at least the late Upper Palaeolithic period. The earliest evidence of occupation in the Sheffield area was found at Creswell Crags to the east of the city. In the Iron Age the area became the southernmost territory of the Pennine tribe called the Brigantes and it is this tribe who are thought to have constructed several hill forts in and around Sheffield. Gradually, Anglian settlers pushed west from the kingdom of Deira, a Celtic presence within the Sheffield area is evidenced by two settlements called Wales and Waleswood close to Sheffield. The settlements that grew and merged to form Sheffield, however, date from the half of the first millennium. In Anglo-Saxon times, the Sheffield area straddled the border between the kingdoms of Mercia and Northumbria, after the Norman conquest, Sheffield Castle was built to protect the local settlements, and a small town developed that is the nucleus of the modern city. By 1296, a market had been established at what is now known as Castle Square, from 1570 to 1584, Mary, Queen of Scots, was imprisoned in Sheffield Castle and Sheffield Manor. During the 1740s, a form of the steel process was discovered that allowed the manufacture of a better quality of steel than had previously been possible

England
–
England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west, the Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east, the country covers five-eighths of the island of Great Britain in its centre and south, and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight. England became a state in the 10th century, and since the Age of Discovery. The Industrial Revolution began in 18th-century England, transforming its society into the worlds first industrialised nation, Englands terrain mostly comprises low hills and plains, especially in central and southern England. However, there are uplands in the north and in the southwest, the capital is London, which is the largest metropolitan area in both the United Kingdom and the European Union. In 1801, Great Britain was united with the Kingdom of Ireland through another Act of Union to become the United Kingdom of Great Britain and Ireland. In 1922 the Irish Free State seceded from the United Kingdom, leading to the latter being renamed the United Kingdom of Great Britain, the name England is derived from the Old English name Englaland, which means land of the Angles. The Angles were one of the Germanic tribes that settled in Great Britain during the Early Middle Ages, the Angles came from the Angeln peninsula in the Bay of Kiel area of the Baltic Sea. The earliest recorded use of the term, as Engla londe, is in the ninth century translation into Old English of Bedes Ecclesiastical History of the English People. According to the Oxford English Dictionary, its spelling was first used in 1538. The earliest attested reference to the Angles occurs in the 1st-century work by Tacitus, Germania, the etymology of the tribal name itself is disputed by scholars, it has been suggested that it derives from the shape of the Angeln peninsula, an angular shape. An alternative name for England is Albion, the name Albion originally referred to the entire island of Great Britain. The nominally earliest record of the name appears in the Aristotelian Corpus, specifically the 4th century BC De Mundo, in it are two very large islands called Britannia, these are Albion and Ierne. But modern scholarly consensus ascribes De Mundo not to Aristotle but to Pseudo-Aristotle, the word Albion or insula Albionum has two possible origins. Albion is now applied to England in a poetic capacity. Another romantic name for England is Loegria, related to the Welsh word for England, Lloegr, the earliest known evidence of human presence in the area now known as England was that of Homo antecessor, dating to approximately 780,000 years ago. The oldest proto-human bones discovered in England date from 500,000 years ago, Modern humans are known to have inhabited the area during the Upper Paleolithic period, though permanent settlements were only established within the last 6,000 years

Tram
–
A tram is a rail vehicle which runs on tracks along public urban streets, and also sometimes on a segregated right of way. The lines or networks operated by tramcars are called tramways, Tramways powered by electricity, the most common type historically, were once called electric street railways. However, trams were used in urban areas before the universal adoption of electrification. Tram lines may run between cities and/or towns, and/or partially grade-separated even in the cities. Very occasionally, trams also carry freight, Tram vehicles are usually lighter and shorter than conventional trains and rapid transit trains, but the size of trams is rapidly increasing. Some trams may also run on railway tracks, a tramway may be upgraded to a light rail or a rapid transit line. For all these reasons, the differences between the modes of rail transportation are often indistinct. In the United States, the tram has sometimes been used for rubber-tired trackless trains. Today, most trams use electrical power, usually fed by a pantograph, in some cases by a sliding shoe on a third rail. If necessary, they may have dual power systems — electricity in city streets, trams are now included in the wider term light rail, which also includes segregated systems. The English terms tram and tramway are derived from the Scots word tram, referring respectively to a type of truck used in coal mines and the tracks on which they ran. The word tram probably derived from Middle Flemish trame, a Romanesque word meaning the beam or shaft of a barrow or sledge, the identical word la trame with the meaning crossbeam is also used in the French language. The word Tram-car is attested from 1873, although the terms tram and tramway have been adopted by many languages, they are not used universally in English, North Americans prefer streetcar, trolley, or trolleycar. The term streetcar is first recorded in 1840, and originally referred to horsecars, when electrification came, Americans began to speak of trolleycars or later, trolleys. The troller design frequently fell off the wires, and was replaced by other more reliable devices. The terms trolley pole and trolley wheel both derive from the troller, Modern trams often have an overhead pantograph mechanical linkage to connect to power, abandoning the trolley pole altogether. Conventional diesel tourist buses decorated to look like streetcars are sometimes called trolleys in the US, the term may also apply to an aerial ropeway, e. g. the Roosevelt Island Tramway. Over time, the trolley has fallen into informal use

Science Museum, London
–
The Science Museum is a major museum on Exhibition Road in South Kensington, London. It was founded in 1857 and today is one of the major tourist attractions. Like other publicly funded museums in the United Kingdom, the Science Museum does not charge visitors for admission. Temporary exhibitions, however, may incur an admission fee and it is part of the Science Museum Group, having merged with the Museum of Science and Industry in Manchester in 2012. It included a collection of machinery which became the Museum of Patents in 1858, and this collection contained many of the most famous exhibits of what is now the Science Museum. In 1883, the contents of the Patent Office Museum were transferred to the South Kensington Museum, in 1885, the Science Collections were renamed the Science Museum and in 1893 a separate director was appointed. The Art Collections were renamed the Art Museum, which became the Victoria. When Queen Victoria laid the stone for the new building for the Art Museum, she stipulated that the museum be renamed after herself. On 26 June 1909 the Science Museum, as an independent entity, the Science Museums present quarters, designed by Sir Richard Allison, were opened to the public in stages over the period 1919–28. This building was known as the East Block, construction of which began in 1913, as the name suggests it was intended to be the first building of a much larger project, which was never realized. It also contains hundreds of interactive exhibits, a recent addition is the IMAX 3D Cinema showing science and nature documentaries, most of them in 3-D, and the Wellcome Wing which focuses on digital technology. Entrance has been free since 1 December 2001, the museum houses some of the many objects collected by Henry Wellcome around a medical theme. The fourth floor exhibit is called Glimpses of Medical History, with reconstructions, the fifth floor gallery is called Science and the Art of Medicine, with exhibits of medical instruments and practices from ancient days and from many countries. The collection is strong in clinical medicine, biosciences and public health, the museum is a member of the London Museums of Health & Medicine. The Science Museum has a library, and until the 1960s was Britains National Library for Science, Medicine. It holds runs of periodicals, early books and manuscripts, and is used by scholars worldwide and it was, for a number of years, run in conjunction with the Library of Imperial College, but in 2007 the Library was divided over two sites. The Imperial College library catalogue search system now informs searchers that volumes formerly held there are Available at Science Museum Library Swindon Currently unavailable, a new Research Centre with library facilities is promised for late 2015 but is unlikely to have book stacks nearby. The Science Museums medical collections have a scope and coverage

Rolling (metalworking)
–
In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough, Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, if the temperature of the metal is below its recrystallization temperature, the process is known as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, Roll stands holding pairs of rolls are grouped together into rolling mills that can quickly process metal, typically steel, into products such as structural steel, bar stock, and rails. Most steel mills have rolling mill divisions that convert the semi-finished casting products into finished products, there are many types of rolling processes, including ring rolling, roll bending, roll forming, profile rolling, and controlled rolling. The invention of the mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the basic principles were found in Middle East. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590 and these passed flat bars between rolls to form a plate of iron, which was then passed between grooved rolls to produce rods of iron. The first experiments at rolling iron for tinplate took place about 1670, in 1697, Major John Hanbury erected a mill at Pontypool to roll Pontypool plates—blackplate. Later this began to be rerolled and tinned to make tinplate, the earlier production of plate iron in Europe had been in forges, not rolling mills. The slitting mill was adapted to producing hoops and iron with a half-round or other sections by means that were the subject of two patents of c. Some of the earliest literature on rolling mills can be traced back to Christopher Polhem in 1761 in Patriotista Testamente and he also explains how rolling mills can save on time and labor because a rolling mill can produce 10 to 20 or more bars at the same time. A patent was granted to Thomas Blockley of England in 1759 for the polishing and rolling of metals, another patent was granted in 1766 to Richard Ford of England for the first tandem mill. A tandem mill is one in which the metal is rolled in successive stands, Fords tandem mill was for hot rolling of wire rods, Rolling mills for lead seem to have existed by the late 17th century. Copper and brass were also rolled by the late 18th century, modern rolling practice can be attributed to the pioneering efforts of Henry Cort of Funtley Iron Mills, near Fareham, England. In 1783 a patent was issued to Henry Cort for his use of grooved rolls for rolling iron bars, with this new design mills were able to produce 15 times more output per day than with a hammer. Although Cort was not the first to use grooved rolls, he was first to combine the use of many of the best features of various ironmaking and shaping processes known at the time, thus modern writers have called him father of modern rolling. The first rail rolling mill was established by John Birkenshaw in 1820, with the advancement of technology in rolling mills the size of rolling mills grew rapidly along with the size products being rolled
