Zerah Colburn (locomotive Designer)
Zerah Colburn (January 13, 1832 – April 26, 1870) was an American engineer specialising in steam locomotive design, technical journalist and publisher. Career Without any formal schooling, Colburn was a teenage prodigy. Barely in his teens at the start of the railroad boom, he found work in Lowell, Massachusetts as an apprentice in the "drafting room" of the Lowell Machine Shops where America’s first steam locomotives were taking shape. While working among the locomotives Colburn also began to write and before long compiled his first regular newssheet – ''Monthly Mechanical Tracts''. As he moved about the locomotive works of New England gathering experience and an eye for engineering detail, he also produced his first book, ''The Throttle Lever''. Designed as an introduction to the steam locomotive, this became the standard U.S. textbook on building locomotives. It not only took Colburn, then not 20, deeper into the world of publishing, but also earned him wider respect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saratoga, New York
} Saratoga is a town in Saratoga County, New York, United States. The population was 5,141 at the 2000 census. It is also the commonly used, but not official, name for the neighboring and much more populous city, Saratoga Springs. The major village in the town of Saratoga is Schuylerville, which is often, but not officially, called Old Saratoga. Saratoga contains a second village, named Victory. ''Saratoga'' is an adaptation of a Native American word from the Mohawk language. It was the name of Indian hunting grounds located along both sides of the Hudson River. According to the town's history, it derives from ''se-rach-ta-gue'', meaning 'the hillside country of the quiet river'. Saratoga is located on the eastern border of the county and is located east of Saratoga Springs, and is bordered by Saratoga Lake and the Hudson River.

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Laudanum
Laudanum is a tincture of opium containing approximately 10% powdered opium by weight (the equivalent of 1% morphine). Laudanum is prepared by dissolving extracts from the opium poppy (''Papaver somniferum Linnaeus'') in alcohol (ethanol). Reddish-brown in color and extremely bitter, laudanum contains several opium alkaloids, including morphine and codeine. Laudanum was historically used to treat a variety of conditions, but its principal use was as a pain medication and cough suppressant. Until the early 20th century, laudanum was sold without a prescription and was a constituent of many patent medicines. Today, laudanum is recognized as addictive and is strictly regulated and controlled as such throughout most of the world. The United States Controlled Substances Act, for one example, lists it on Schedule II, the second strictest category. Laudanum is known as a "whole opium" preparation since it historically contained all the alkaloids found in the opium poppy, which are ...

Bigamy
In cultures where monogamy is mandated, bigamy is the act of entering into a marriage with one person while still legally married to another. A legal or de facto separation of the couple does not alter their marital status as married persons. In the case of a person in the process of divorcing their spouse, that person is taken to be legally married until such time as the divorce becomes final or absolute under the law of the relevant jurisdiction. Bigamy laws do not apply to couples in a de facto or cohabitation relationship, or that enter such relationships when one is legally married. If the prior marriage is for any reason void, the couple is not married, and hence each party is free to marry another without falling foul of the bigamy laws. Bigamy is a crime in most countries that recognise only monogamous marriages. When it occurs in this context often neither the first nor second spouse is aware of the other. In countries that have bigamy laws, with a few exceptions (suc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zerah Colburn (math Prodigy)
Zerah Colburn (September 1, 1804 – March 2, 1839) was an American child prodigy of the 19th century who gained fame as a mental calculator.W. W. Rouse Ball (1960) ''Calculating Prodigies'', in Mathematical Recreations and Essays, Macmillan, New York, chapter 13. Biography Colburn was born in Cabot, Vermont, in 1804. He was thought to be intellectually disabled until the age of six. However, after six weeks of schooling, his father overheard him repeating his multiplication tables. His father was not sure whether or not he learned the tables from his older brothers and sisters, but he decided to test him further on his mathematical abilities and discovered that there was something special about his son when Zerah correctly multiplied 13 and 97. Colburn's abilities developed rapidly and he was soon able to solve such problems as the number of seconds in 2,000 years, the product of 12,225 and 1,223, or the square root of 1,449. When he was seven years old he took six seconds to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bessemer Process
The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace. The key principle is steelmaking, removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten. Related Decarburization, decarburizing with air processes had been used outside Europe for hundreds of years, but not on an industrial scale. One such process (similar to puddling (metallurgy), puddling) was known in the 11th century in East Asia, where the scholar Shen Kuo of that era described its use in the Chinese iron and steel industry. In the 17th century, accounts by European travelers detailed its possible use by the Japanese. The modern process is named after its inventor, the Englishman Henry Bessemer, who took out a patent on the process in 1856. The process was said to be independently discover ...

Henry Bessemer
Sir Henry Bessemer (19 January 1813 – 15 March 1898) was an English inventor, whose steel-making process would become the most important technique for making steel in the nineteenth century for almost one hundred years from 1856 to 1950. He also played a significant role in establishing the town of Sheffield, nicknamed ‘Steel City’, as a major industrial centre. Bessemer had been trying to reduce the cost of steel-making for military ordnance, and developed his system for blowing air through molten pig iron to remove the impurities. This made steel easier, quicker and cheaper to manufacture, and revolutionised structural engineering. One of the most significant inventors of the Second Industrial Revolution, Bessemer also made over 100 other inventions in the fields of iron, steel and glass. Unlike many inventors, he managed to bring his own projects to fruition and profited financially from their success. He was knighted for his contribution to science in 1879, and in th ...

Engineering (magazine)
''Engineering'' is a monthly British magazine founded in 1865. It was initially published by the Office for Publication and Advertisements and reported on developments and news in many disciplines of engineering in Britain and abroad. It is now produced and published by Media Culture PLC and has the strapline "for innovators in technology, manufacturing and management". History The ''Engineering'' magazine was founded in 1866 by the American engineer and locomotive designer Zerah Colburn in London as a weekly rival to '' The Engineer''. It had the subtitle "an illustrated weekly journal". Colburn had used funds provided by Henry Bessemer, the English engineer and inventor known chiefly in connection with the Bessemer process for the manufacture of steel. ''Engineering'' was an instant success and soon overtook ''The Engineer'' as Colburn's writing style and wide engineering knowledge gave readers the information they needed.

Telford Medal
The Telford Medal is a prize awarded by the British Institution of Civil Engineers (ICE) for a paper or series of papers. It was introduced in 1835 following a bequest made by Thomas Telford, the ICE's first president. It can be awarded in gold, silver or bronze; the Telford Gold Medal is the highest award the institution can bestow. History In 1834 Scottish civil engineer and the Institution of Civil Engineers' first president (1820-1834), Thomas Telford died, leaving in his will his library of technical works to the Institution of Civil Engineers, as well as a bequest of £2000; the interest from which was to be used to for the purpose of "Annual Premiums". The council of the institute decided to expend the premiums on both honorary and monetary rewards, the honorary awards being named Telford Medals, which would be awarded in gold, silver and bronze forms. Suitable candidates for the awards were submitters of drawings, models, diagrams or essays relating to civil engineering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

SS Great Eastern
SS ''Great Eastern'' was an iron sail-powered, paddle wheel and screw-propelled steamship designed by Isambard Kingdom Brunel, and built by John Scott Russell & Co. at Millwall Iron Works on the River Thames, London. She was the largest ship ever built at the time of her 1858 launch, and had the capacity to carry 4,000 passengers from England to Australia without refuelling. Her length of was surpassed only in 1899 by the 17,274-gross-ton , her gross tonnage of 18,915 was only surpassed in 1901 by the 20,904-gross-ton and her 4,000-passenger capacity was surpassed in 1913 by the 4,234-passenger . The ship having five funnels (which were later reduced to four) was unusual for the time. The vessel also had the largest set of paddle wheels. Brunel knew her affectionately as the "Great Babe". He died in 1859 shortly after her maiden voyage, during which she was damaged by an explosion. After repairs, she plied for several years as a passenger liner between Britain and North Ame ...

Isambard Kingdom Brunel
Isambard Kingdom Brunel (; 9 April 1806 – 15 September 1859) was a British civil engineer who is considered "one of the most ingenious and prolific figures in engineering history," "one of the 19th-century engineering giants," and "one of the greatest figures of the Industrial Revolution, hochanged the face of the English landscape with his groundbreaking designs and ingenious constructions." Brunel built dockyards, the Great Western Railway (GWR), a series of steamships including the first propeller-driven transatlantic steamship, and numerous important bridges and tunnels. His designs revolutionised public transport and modern engineering. Though Brunel's projects were not always successful, they often contained innovative solutions to long-standing engineering problems. During his career, Brunel achieved many engineering firsts, including assisting in the building of the first tunnel under a navigable river (the River Thames) and the development of the , the first ...
