2 Logical Empiricism
Modern analytical empiricism... differs from that of Locke, Berkeley, and Hume by its incorporation of mathematics and its development of a powerful logical technique. It is thus able, in regard to certain problems, to achieve definite answers, which have the quality of science rather than of philosophy. It has the advantage, as compared with the philosophies of the system-builders, of being able to tackle its problems one at a time, instead of having to invent at one stroke a block theory of the whole universe. Its methods, in this respect, resemble those of science. I have no doubt that, in so far as philosophical knowledge is possible, it is by such methods that it must be sought: I also have no doubt that, by these methods, many ancient problems are completely soluble.... Take such questions as: What is number? What are space and time? What is mind, and what is matter? I do not say that we can here and now give definitive answers to all these ancient questions, but I do say that a method has been discovered by which, as in science, we can make successive approximations to the truth, in which each new stage results from an improvement, not a rejection, of what has gone before. (Russell, 1961, pp. 788-789)Not a single one of the great theses of Logical Empiricism (that Meaning is Method of Verification; that metaphysical propositions are literally without sense; that Mathematics is True by Convention) has turned out to be correct. It detracts from the excitement of the fact that, by turning philosophical theses into linguistic ones [as Carnap had tried to do]... one can make philosophy more scientific and settle the truth value of philosophical propositions by hard scientific research, if the results one obtains are uniformly negative. (Putnam, 1975, p. 20)Historical dictionary of quotations in cognitive science > Logical Empiricism

5 Chapelon, André
[br]b. 26 October 1892 Saint-Paul-en-Cornillon, Loire, Franced. 29 June 1978 Paris, France[br]French locomotive engineer who developed high-performance steam locomotives.[br]Chapelon's technical education at the Ecole Centrale des Arts et Manufactures, Paris, was interrupted by extended military service during the First World War. From experience of observing artillery from the basket of a captive balloon, he developed a method of artillery fire control which was more accurate than that in use and which was adopted by the French army.In 1925 he joined the motive-power and rolling-stock department of the Paris-Orléans Railway under Chief Mechanical Engineer Maurice Lacoin and was given the task of improving the performance of its main-line 4–6–2 locomotives, most of them compounds. He had already made an intensive study of steam locomotive design and in 1926 introduced his Kylchap exhaust system, based in part on the earlier work of the Finnish engineer Kyläla. Chapelon improved the entrainment of the hot gases in the smokebox by the exhaust steam and so minimized back pressure in the cylinders, increasing the power of a locomotive substantially. He also greatly increased the cross-sectional area of steam passages, used poppet valves instead of piston valves and increased superheating of steam. PO (Paris-Orléans) 4–6–2s rebuilt on these principles from 1929 onwards proved able to haul 800-ton trains, in place of the previous 500-ton trains, and to do so to accelerated schedules with reduced coal consumption. Commencing in 1932, some were converted, at the time of rebuilding, into 4–8–0s to increase adhesive weight for hauling heavy trains over the steeply graded Paris-Toulouse line.Chapelon's principles were quickly adopted on other French railways and elsewhere.H.N. Gresley was particularly influenced by them. After formation of the French National Railways (SNCF) in 1938, Chapelon produced in 1941 a prototype rebuilt PO 2–10–0 freight locomotive as a six-cylinder compound, with four low-pressure cylinders to maximize expansive use of steam and with all cylinders steam-jacketed to minimize heat loss by condensation and radiation. War conditions delayed extended testing until 1948–52. Meanwhile Chapelon had, by rebuilding, produced in 1946 a high-powered, three-cylinder, compound 4–8–4 intended as a stage in development of a proposed range of powerful and thermally efficient steam locomotives for the postwar SNCF: a high-speed 4–6–4 in this range was to run at sustained speeds of 125 mph (200 km/h). However, plans for improved steam locomotives were then overtaken in France by electriflcation and dieselization, though the performance of the 4–8–4, which produced 4,000 hp (3,000 kW) at the drawbar for the first time in Europe, prompted modification of electric locomotives, already on order, to increase their power.Chapelon retired from the SNCF in 1953, but continued to act as a consultant. His principles were incorporated into steam locomotives built in France for export to South America, and even after the energy crisis of 1973 he was consulted on projects to build improved, high-powered steam locomotives for countries with reserves of cheap coal. The eventual fall in oil prices brought these to an end.[br]Bibliography1938, La Locomotive à vapeur, Paris: J.B.Bailière (a comprehensive summary of contemporary knowledge of every function of the locomotive).Further ReadingH.C.B.Rogers, 1972, Chapelon, Genius of French Steam, Shepperton: Ian Allan.1986, "André Chapelon, locomotive engineer: a survey of his work", Transactions of the Newcomen Society 58 (a symposium on Chapelon's work).Obituary, 1978, Railway Engineer (September/October) (makes reference to the technical significance of Chapelon's work).PJGR
