Samuel Bentham
Sir Samuel Bentham (11 January 1757 – 31 May 1831) was a noted English mechanical engineer and naval architect credited with numerous innovations, particularly related to naval architecture, including weapons. He was the only surviving sibling of philosopher Jeremy Bentham, with whom he had a close bond. Early life Samuel Bentham was one of two surviving children of Jeremiah Bentham. His father was an attorney, and his older brother was the philosopher Jeremy Bentham, five other siblings having died in infancy or early childhood, and their mother dying in 1766. At the age of 14, Bentham was apprenticed to a shipwright at Woolwich Dockyard, serving there and at Chatham Dockyard, before completing his 7-year training at the Naval Academy in Portsmouth. Career Russia In 1780 he moved to Russia, where he was employed in the service of Prince Potemkin, who had an establishment designed to promote the introduction of various arts of civilization. Initially hired as a shipbuilde ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
London
London is the capital and List of urban areas in the United Kingdom, 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 Roman Empire, Romans as ''Londinium'' and retains its medieval boundaries.See also: Independent city#National capitals, Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national Government of the United Kingdom, government and Parliament of the United Kingdom, parliament.

Siberian Route
The Siberian Route (russian: Сибирский тракт; ''Sibirsky trakt''), also known as the Moscow Highway (, Московский тракт) and Great Highway (, Большой тракт), was a historic route that connected European Russia to Siberia and China. History The construction of the road was decreed by the Tsar and was not finished until the mid-19th century. Previously, Siberian transport had been mostly by river via Siberian River Routes. The first Russian settlers arrived in Siberia by the Cherdyn river route which was superseded by the Babinov overland route in the late 1590s. The town of Verkhoturye in the Urals was the most eastern point of the Babinov Road. The much longer Siberian route started in Moscow as the Vladimir Highway and passed through Murom, Kozmodemyansk, Kazan, Perm, Kungur, Yekaterinburg, Tyumen, Tobolsk, Tara, Kainsk, Tomsk, Yeniseysk and Irkutsk. After crossing Lake Baikal the road split near Verkhneudinsk. One branch continue ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Maudslay
Henry Maudslay ( pronunciation and spelling) (22 August 1771 – 14 February 1831) was an English machine tool innovator, tool and die maker, and inventor. He is considered a founding father of machine tool technology. His inventions were an important foundation for the Industrial Revolution. Maudslay's invention of a metal lathe to cut metal, circa 1800, enabled the manufacture of standard screw thread sizes. Standard screw thread sizes allowed interchangeable parts and the development of mass production. Early life Maudslay was the fifth of seven children of Henry Maudslay, a wheelwright in the Royal Engineers, and Margaret (''nee'' Whitaker), the young widow of Joseph Laundy. His father was wounded in action and so in 1756 became an 'artificer' at the Royal Arsenal, Woolwich (then in Kent), where he remained until 1776 and died in 1780. The family lived in an alley that no longer exists, off Beresford Square, between Powis Street and Beresford Street. Career Maudsla ...

Marc Isambard Brunel
Sir Marc Isambard Brunel (, ; 25 April 1769 – 12 December 1849) was a French-British engineer who is most famous for the work he did in Britain. He constructed the Thames Tunnel and was the father of Isambard Kingdom Brunel. Born in France, Brunel fled to the United States during the French Revolution. In 1796, he was appointed Chief Engineer of New York City. He moved to London in 1799, where he married Sophia Kingdom. In addition to the construction of the Thames Tunnel, his work as a mechanical engineer included the design of machinery to automate the production of pulley blocks for the Royal Navy. Brunel preferred the given name Isambard, but is generally known to history as Marc to avoid confusion with his more famous son. Early life in France Brunel was the second son of Jean Charles Brunel and Marie-Victoire Lefebvre. Jean Charles was a prosperous farmer in Hacqueville, Normandy, and Marc was born on the family farm. It was customary for the first son to inher ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Block (sailing)
In sailing, a block is a single or multiple pulley. One or a number of '' sheaves'' are enclosed in an assembly between ''cheeks'' or ''chocks''. In use, a block is fixed to the end of a line, to a spar, or to a surface. A line (rope) is ''reeved'' through the sheaves, and maybe through one or more matching blocks at some far end, to make up a tackle. The ''purchase'' of a tackle refers to its mechanical advantage. In general the more sheaves in the blocks that make up a tackle, the higher its mechanical advantage. The matter is slightly complicated by the fact that every tackle has a ''working end'' where the final run of rope leaves the last sheave. More mechanical advantage can be obtained if this end is attached to the moving load rather than the fixed end of the tackle. There are various types of blocks that are used in sailing. Some blocks are used to increase mechanical advantage and others are used simply to change the direction of a line. A ''ratchet block'' turns fr ...

Navy Board
The Navy Board (formerly known as the Council of the Marine or Council of the Marine Causes) was the commission responsible for the day-to-day civil administration of the Royal Navy between 1546 and 1832. The board was headquartered within the Navy Office. History The origins of the Navy Board can be traced back to the 13th century via the office Keeper of the King's Ports and Galleys; later known as the Clerk of the King's Ships. The management of the navy expanded with the Keeper of the Storehouses appointed in 1514 and the Clerk Comptroller in 1522. The Lieutenant of the Admiralty, Treasurer of Marine Causes and Surveyor and Rigger of the Navy were all added in 1544, and a seventh officer, the Master of Naval Ordnance a year later. By January 1545 this group was already working as a body known as the Council of the Marine or ''King's Majesty's Council of His Marine''. In the first quarter of 1545 an official memorandum proposed the establishment of a new organisati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surveyor Of Buildings (Royal Navy)
The Surveyor of Buildings also known as the Department of the Surveyor of Buildings was the civil officer initially a member of the Navy Board then later the Board of Admiralty responsible for superintending, maintaining and improving the British Royal Navy Dockyards, Naval Buildings, and Architectural Works of the Admiralty from 1812 to 1837. History The office holder evolved out of an earlier post in 1796 when an '' Inspector-General of Naval Works'' was appointed to superintend the Naval Works Department then under the Board of Admiralty with responsibility for all civil engineering works in the royal naval dockyards. In 1806 the ''Commissioners of Enquiry for Revising and Digesting the Civil Affairs of the Royal Navy'' produced a fourth report (since 1785) in which they recommended the abolition of the Inspector-Generals Department as a semi-autonomous function and recommended the role be re-styled and its responsibilities broadened. In 1807 the title was changed to the ''Ci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Redbridge, Hampshire
Redbridge is a ward with a population of 14,432, to the west of the city centre of Southampton, England. The settlement is positioned at the mouth of the River Test and is the southern terminus of the former Andover Canal and Sprat and Winkle railway line, and the modern M271 motorway. Because of its strategic position, the settlement became a substantial trading post and shipbuilding centre, with many merchant and Royal Navy vessels being constructed in Redbridge in the 18th and 19th centuries. Today, the area is mainly residential and industrial, with a large council estate and a tower block situated within the ward and Southampton Docks close by. The A35 road crosses the River Test at Redbridge, as does the South West Main Line railway. It has a small railway station. Etymology Redbridge has been known by several names, all derived from its position as a crossing point over the River Test – originally as a ford and later with the bridge that gives the area its curren ...

George Fordyce
George Fordyce (18 November 1736 – 25 May 1802) was a distinguished Scottish physician, lecturer on medicine, and chemist, who was a Fellow of the Royal Society and a Fellow of the Royal College of Physicians. Early life George Fordyce was born at Aberdeen in 1736, a short time after the death of his father, George Fordyce, proprietor of a small landed estate called Broadford, near the city. He was taken from home at the age of two following his mother's remarriage and was sent to Foveran, Aberdeenshire, where he received his schooling. Following that he attended the University of Aberdeen where he attained the degree of Master of Arts at the age of 14. Career Fordyce had decided to study medicine and was apprenticed to his uncle, Dr. John Fordyce, in Uppingham, in Rutland. He later returned to the University of Edinburgh, where he took his degree of M.D. in 1758; his inaugural dissertation was on catarrh. From Edinburgh he went to Leyden, where he studied anato ...

Watertight Compartment
A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads. It is analogous to a room within a building, and may provide watertight subdivision of the ship's hull important in retaining buoyancy if the hull is damaged. Subdivision of a ship's hull into watertight compartments is called compartmentation. History Bulkhead watertight compartments were originally invented by the Chinese. These compartments strengthened the junks and slowed flooding in case of holing during the Han and Song dynasties. The wide application of Chinese watertight compartments soon spread to the Europeans through the Indian and Arab merchants. The economics of early unsinkable passenger ships was scrutinized in an 1882 Scientific American article. Watertight subdivision Watertight subdivision limits loss of buoyancy and freeboard in the event of damage, and may protect vital machinery from flooding. Most ships have some pumping capacit ...

Junk (ship)
A junk (Chinese: 船, ''chuán'') is a type of Chinese sailing ship with fully battened sails. There are two types of junk in China: northern junk, which developed from Chinese river boats, and southern junk, which developed from Austronesian ships visiting southern Chinese coasts since the 3rd century CE. They continued to evolve in later dynasties and were predominantly used by Chinese traders throughout Southeast Asia. Similar junk sails were also adopted by other East Asian countries, most notably Japan where junks were used as merchant ships to trade goods with China and Southeast Asia. They were found, and in lesser numbers are still found, throughout Southeast Asia and India, but primarily in China. Historically, a Chinese junk could be one of many types of small coastal or river ships, usually serving as a cargo ship, pleasure boat, or houseboat, but also ranging in size up to large ocean-going vessel. Found more broadly today is a growing number of modern recreationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
