65 Phillips, Edouard
SUBJECT AREA: Mechanical, pneumatic and hydraulic engineering[br]b. 21 May 1821 Paris, Franced. 14 December 1889 Pouligny-Saint-Martin, France[br]French engineer and mathematician who achieved isochronous oscillations of a balance by deriving the correct shape for the balance spring.[br]Phillips was educated in Paris, at the Ecole Polytechnic and the Ecole des Mines. In 1849 he was awarded a doctorate in mathematical sciences by the University of Paris. He had a varied career in industry, academic and government institutions, rising to be Inspector- General of Mines in 1882.It was well known that the balance of a watch or chronometer fitted with a simple spiral or helical spring was not isochronous, i.e. the period of the oscillation was not entirely independent of the amplitude. Watch-and chronometer-makers, notably Breguet and Arnold, had devised empirical solutions to the problem by altering the curvature of the end of the balance spring. In 1858 Phillips was encouraged to tackle the problem mathematically, and two years later he published a complete solution for the helical balance spring and a partial solution for the more complex spiral spring. Eleven years later he was able to achieve a complete solution for the spiral spring by altering the curvature of both ends of the spring. Phillips published a series of typical curves that the watch-or chronometer-maker could use to shape the ends of the balance spring.[br]Principal Honours and DistinctionsAcadémie des Sciences 1868.

66 Riley, James
SUBJECT AREA: Metallurgy[br]b. 1840 Halifax, Englandd. 15 July 1910 Harrogate, England[br]English steelmaker who promoted the manufacture of low-carbon bulk steel by the open-hearth process for tin plate and shipbuilding; pioneer of nickel steels.[br]After working as a millwright in Halifax, Riley found employment at the Ormesby Ironworks in Middlesbrough until, in 1869, he became manager of the Askam Ironworks in Cumberland. Three years later, in 1872, he was appointed Blast-furnace Manager at the pioneering Siemens Steel Company's works at Landore, near Swansea in South Wales. Using Spanish ore, he produced the manganese-rich iron (spiegeleisen) required as an additive to make satisfactory steel. Riley was promoted in 1874 to be General Manager at Landore, and he worked with William Siemens to develop the use of the latter's regenerative furnace for the production of open-hearth steel. He persuaded Welsh makers of tin plate to use sheets rolled from lowcarbon (mild) steel instead of from charcoal iron and, partly by publishing some test results, he was instrumental in influencing the Admiralty to build two naval vessels of mild steel, the Mercury and the Iris.In 1878 Riley moved north on his appointment as General Manager of the Steel Company of Scotland, a firm closely associated with Charles Tennant that was formed in 1872 to make steel by the Siemens process. Already by 1878, fourteen Siemens melting furnaces had been erected, and in that year 42,000 long tons of ingots were produced at the company's Hallside (Newton) Works, situated 8 km (5 miles) south-east of Glasgow. Under Riley's leadership, steelmaking in open-hearth furnaces was initiated at a second plant situated at Blochairn. Plates and sections for all aspects of shipbuilding, including boilers, formed the main products; the company also supplied the greater part of the steel for the Forth (Railway) Bridge. Riley was associated with technical modifications which improved the performance of steelmaking furnaces using Siemens's principles. He built a gasfired cupola for melting pig-iron, and constructed the first British "universal" plate mill using three-high rolls (Lauth mill).At the request of French interests, Riley investigated the properties of steels containing various proportions of nickel; the report that he read before the Iron and Steel Institute in 1889 successfully brought to the notice of potential users the greatly enhanced strength that nickel could impart and its ability to yield alloys possessing substantially lower corrodibility.The Steel Company of Scotland paid dividends in the years to 1890, but then came a lean period. In 1895, at the age of 54, Riley moved once more to another employer, becoming General Manager of the Glasgow Iron and Steel Company, which had just laid out a new steelmaking plant at Wishaw, 25 km (15 miles) south-east of Glasgow, where it already had blast furnaces. Still the technical innovator, in 1900 Riley presented an account of his experiences in introducing molten blast-furnace metal as feed for the open-hearth steel furnaces. In the early 1890s it was largely through Riley's efforts that a West of Scotland Board of Conciliation and Arbitration for the Manufactured Steel Trade came into being; he was its first Chairman and then its President.In 1899 James Riley resigned from his Scottish employment to move back to his native Yorkshire, where he became his own master by acquiring the small Richmond Ironworks situated at Stockton-on-Tees. Although Riley's 1900 account to the Iron and Steel Institute was the last of the many of which he was author, he continued to contribute to the discussion of papers written by others.[br]Principal Honours and DistinctionsPresident, West of Scotland Iron and Steel Institute 1893–5.

Words are but the images of matter... to fall in love with them is all one as to fall in love with a picture. (Bacon, 1878, p. 120)Chamberlin, Tracy, Dewey, Binet and others have shown that the child's symbols are action-words, i.e., their content is action. There is also practically universal agreement on the fact that the first symbols of the child are in reality word-sentences designating action and object or subject, or all three at once. (Markey, 1928, p. 50)The child can very readily learn at the age of three that "right" and "left" each refers to a side of the body-but ah me, which one?... What is set up first is a conceptual organization. By the age of six the word "right" clearly and immediately means sidedness to the child. A considerable conceptual elaboration has already occurred, and the stimulus effectively arouses that structure; but it arouses no prompt, specific response.... With such facts, it becomes nonsense to explain man's conceptual development as exclusively consisting of verbal associations. (Hebb, 1949, p. 118)The use of language is not confined to its being the medium through which we communicate ideas to one another.... Words are the instrument by which we form all our abstractions, by which we fashion and embody our ideas, and by which we are enabled to glide along a series of premises and conclusions with a rapidity so great as to leave in memory no trace of the successive steps of this process; and we remain unconscious of how much we owe to this. (Roget, quoted in Minsky, 1986, p. 197)Any attempt at a philosophical arrangement under categories of the words of our language must reveal the fact that it is impossible to separate and circumscribe the several groups by absolutely distinct boundaries. Were we to disengage their interwoven ramifications, and seek to confine every word to its main or original meaning, we should find some secondary meaning has become so firmly associated with many words and phrases, that to sever the alliance would be to deprive our language of the richness due to an infinity of natural adaptations.
