1 Thomson, James
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 16 February 1822 Belfast, Ireland (now Northern Ireland)d. 8 May 1892 Glasgow, Scotland[br]Irish civil engineer noted for his work in hydraulics and for his design of the "Vortex" turbine.[br]James Thomson was a pupil in several civil-engineering offices, but the nature of the work was beyond his physical capacity and from 1843 onwards he devoted himself to theoretical studies. Hhe first concentrated on the problems associated with the expansion of liquids when they reach their freezing point: water is one such example. He continued this work with his younger brother, Lord Kelvin (see Thomson, Sir William).After experimentation with a "feathered" paddle wheel as a young man, he turned his attention to water power. In 1850 he made his first patent application, "Hydraulic machinery and steam engines": this patent became his "Vortex" turbine design. He settled in Belfast, the home of the MacAdam-Fourneyron turbine, in 1851, and as a civil engineer became the Resident Engineer to the Belfast Water Commissioners in 1853. In 1857 he was appointed Professor of Civil Engineering and Surveying at Queen's College, Belfast.Whilst it is understood that he made his first turbine models in Belfast, he came to an arrangement with the Williamson Brothers of Kendal to make his turbine. In 1856 Williamsons produced their first turbine to Thomson's design and drawings. This was the Vortex Williamson Number 1, which produced 5 hp (3.7 kW) under a fall of 31 ft (9.4 m) on a 9 in. (23 cm) diameter supply. The rotor of this turbine ran in a horizontal plane. For several years the Williamson catalogue described their Vortex turbine as "designed by Professor James Thomson".Thomson continued with his study of hydraulics and water flow both at Queen's College, Belfast, and, later, at Glasgow University, where he became Professor in 1873, succeeding Macquorn Rankine, another famous engineer. At Glasgow, James Thomson studied the flow in rivers and the effects of erosion on river beds. He was also an authority on geological formations such as the development of the basalt structure of the Giant's Causeway, north of Belfast.James Thomson was an extremely active engineer and a very profound teacher of civil engineering. His form of water turbine had a long life before being displaced by the turbines designed in the twentieth century.[br]Bibliography1850, British patent no. 13,156 "Hydraulic machinery and steam engines".Further ReadingGilkes, 1956, One Hundred Years of Water Power, Kendal.KM -
2 Maxwell, James Clerk
[br]b. 13 June 1831 Edinburgh, Scotlandd. 5 November 1879 Cambridge, England[br]Scottish physicist who formulated the unified theory of electromagnetism, the kinetic theory of gases and a theory of colour.[br]Maxwell attended school at the Edinburgh Academy and at the age of 16 went on to study at Edinburgh University. In 1850 he entered Trinity College, Cambridge, where he graduated four years later as Second Wrangler with the award of the Smith's Prize. Two years later he was appointed Professor at Marischal College, Aberdeen, where he married the Principal's daughter. In 1860 he moved to King's College London, but on the death of his father five years later, Maxwell returned to the family home in Scotland, where he continued his researches as far as the life of a gentleman farmer allowed. This rural existence was interrupted in 1874 when he was persuaded to accept the chair of Cavendish Professor of Experimental Physics at Cambridge. Unfortunately, in 1879 he contracted the cancer that brought his brilliant career to an untimely end. While at Cambridge, Maxwell founded the Cavendish Laboratory for research in physics. A succession of distinguished physicists headed the laboratory, making it one of the world's great centres for notable discoveries in physics.During the mid-1850s, Maxwell worked towards a theory to explain electrical and magnetic phenomena in mathematical terms, culminating in 1864 with the formulation of the fundamental equations of electromagnetism (Maxwell's equations). These equations also described the propagation of light, for he had shown that light consists of transverse electromagnetic waves in a hypothetical medium, the "ether". This great synthesis of theories uniting a wide range of phenomena is worthy to set beside those of Sir Isaac Newton and Einstein. Like all such syntheses, it led on to further discoveries. Maxwell himself had suggested that light represented only a small part of the spectrum of electromagnetic waves, and in 1888 Hertz confirmed the discovery of another small part of the spectrum, radio waves, with momentous implications for the development of telecommunication technology. Maxwell contributed to the kinetic theory of gases, which by then were viewed as consisting of a mass of randomly moving molecules colliding with each other and with the walls of the containing vessel. From 1869 Maxwell applied statistical methods to describe the molecular motion in mathematical terms. This led to a greater understanding of the behaviour of gases, with important consequences for the chemical industry.Of more direct technological application was Maxwell's work on colour vision, begun in 1849, showing that all colours could be derived from the three primary colours, red, yellow and blue. This enabled him in 1861 to produce the first colour photograph, of a tartan. Maxwell's discoveries about colour vision were quickly taken up and led to the development of colour printing and photography.[br]BibliographyMost of his technical papers are reprinted in The Scientific Papers of J.Clerk Maxwell, 1890, ed. W.D.Niven, Cambridge, 2 vols; reprinted 1952, New York.Maxwell published several books, including Theory of Heat, 1870, London (1894, 11th edn, with notes by Lord Rayleigh) and Theory of Electricity and Magnetism, 1873, Oxford (1891, ed. J.J.Thomson, 3rd edn).Further ReadingL.Campbell and W.Garnett, 1882, The Life of James Clerk Maxwell, London (the standard biography).J.J.Thomson (ed.), 1931, James Clerk Maxwell 1831–1931, Cambridge.

Rule Britannia es una canción patriótica que data de 1740. La letra, escrita por el poeta escocés James Thomson, celebra el control marítimo del que Gran Bretaña disfrutaba en aquella época. Aunque algunos critican el tono excesivamente chovinista de la canción, Rule Britannia aún se canta en algunas celebraciones de carácter patriótico, como la Last Night of the Proms. El estribillo reza así: Rule Britannia, Britannia rule the waves, Britons never never never shall be slaves.

8 Napier, Robert
SUBJECT AREA: Ports and shipping[br]b. 18 June 1791 Dumbarton, Scotlandd. 23 June 1876 Shandon, Dunbartonshire, Scotland[br]Scottish shipbuilder one of the greatest shipbuilders of all time, known as the "father" of Clyde shipbuilding.[br]Educated at Dumbarton Grammar School, Robert Napier had been destined for the Church but persuaded his father to let him serve an apprenticeship as a blacksmith under him. For a while he worked in Edinburgh, but then in 1815 he commenced business in Glasgow, the city that he served for the rest of his life. Initially his workshop was in Camlachie, but it was moved in 1836 to a riverside factory site at Lancefield in the heart of the City and again in 1841 to the Old Shipyard in the Burgh of Govan (then independent of the City of Glasgow). The business expanded through his preparedness to build steam machinery, beginning in 1823 with the engines for the paddle steamer Leven, still to be seen a few hundred metres from Napier's grave in Dumbarton. His name assured owners of quality, and business expanded after two key orders: one in 1836 for the Honourable East India Company; and the second two years later for the Royal Navy, hitherto the preserve of the Royal Dockyards and of the shipbuilders of south-east England. Napier's shipyard and engine shops, then known as Robert Napier and Sons, were to be awarded sixty Admiralty contracts in his lifetime, with a profound influence on ship and engine procurement for the Navy and on foreign governments, which for the first time placed substantial work in the United Kingdom.Having had problems with hull subcontractors and also with the installation of machinery in wooden hulls, in 1843 Napier ventured into shipbuilding with the paddle steamer Vanguard, which was built of iron. The following year the Royal Navy took delivery of the iron-hulled Jackall, enabling Napier to secure the contract for the Black Prince, Britain's second ironclad and sister ship to HMS Warrior now preserved at Portsmouth. With so much work in iron Napier instigated studies into metallurgy, and the published work of David Kirkaldy bears witness to his open-handedness in assisting the industry. This service to industry was even more apparent in 1866 when the company laid out the Skelmorlie Measured Mile on the Firth of Clyde for ship testing, a mile still in use by ships of all nations.The greatest legacy of Robert Napier was his training of young engineers, shipbuilders and naval architects. Almost every major Scottish shipyard, and some English too, was influenced by him and many of his early foremen left to set up rival establishments along the banks of the River Clyde. His close association with Samuel Cunard led to the setting up of the company now known as the Cunard Line. Napier designed and engined the first four ships, subcontracting the hulls of this historic quartet to other shipbuilders on the river. While he contributed only 2 per cent to the equity of the shipping line, they came back to him for many more vessels, including the magnificent paddle ship Persia, of 1855.It is an old tradition on the Clyde that the smokestacks of ships are made by the enginebuilders. The Cunard Line still uses red funnels with black bands, Napier's trademark, in honour of the engineer who set them going.[br]Principal Honours and DistinctionsKnight Commander of the Dannebrog (Denmark).
