114 Caetano, Marcello José das Neves Alves
(19061980)Marcello Caetano, as the last prime minister of the Estado Novo, was both the heir and successor of Antônio de Oliveira Salazar. In a sense, Caetano was one of the founders and sustainers of this unusual regime and, at various crucial stages of its long life, Caetano's contribution was as important as Salazar's.Born in Lisbon in 1906 to a middle-class family, Caetano was a member of the student generation that rebelled against the unstable parliamentary First Republic and sought answers to Portugal's legion of troubles in conservative ideologies such as integralism, Catholic reformism, and the Italian Fascist model. One of the most brilliant students at the University of Lisbon's Law School, Caetano soon became directly involved in government service in various ministries, including Salazar's Ministry of Finance. When Caetano was not teaching full-time at the law school in Lisbon and influencing new generations of students who became critical of the regime he helped construct, Caetano was in important government posts and working on challenging assignments. In the 1930s, he participated in reforms in the Ministry of Finance, in the writing of the 1933 Constitution, in the formation of the new civil code, of which he was in part the author, and in the construction of corporativism, which sought to control labor-management relations and other aspects of social engineering. In a regime largely directed by academics from the law faculties of Coimbra University and the University of Lisbon, Caetano was the leading expert on constitutional law, administrative law, political science, and colonial law. A prolific writer as both a political scientist and historian, Caetano was the author of the standard political science, administrative law, and history of law textbooks, works that remained in print and in use among students long after his exile and death.After his apprenticeship service in a number of ministries, Caetano rose steadily in the system. At age 38, he was named minister for the colonies (1944 47), and unlike many predecessors, he "went to see for himself" and made important research visits to Portugal's African territories. In 1955-58, Caetano served in the number-three position in the regime in the Ministry of the Presidency of the Council (premier's office); he left office for full-time academic work in part because of his disagreements with Salazar and others on regime policy and failures to reform at the desired pace. In 1956 and 1957, Caetano briefly served as interim minister of communications and of foreign affairs.Caetano's opportunity to take Salazar's place and to challenge even more conservative forces in the system came in the 1960s. Portugal's most prominent law professor had a public falling out with the regime in March 1962, when he resigned as rector of Lisbon University following a clash between rebellious students and the PIDE, the political police. When students opposing the regime organized strikes on the University of Lisbon campus, Caetano resigned his rectorship after the police invaded the campus and beat and arrested some students, without asking permission to enter university premises from university authorities.When Salazar became incapacitated in September 1968, President Américo Tomás named Caetano prime minister. His tasks were formidable: in the midst of remarkable economic growth in Portugal, continued heavy immigration of Portuguese to France and other countries, and the costly colonial wars in three African colonies, namely Angola, Guinea- Bissau, and Mozambique, the regime struggled to engineer essential social and political reforms, win the wars in Africa, and move toward meaningful political reforms. Caetano supported moderately important reforms in his first two years in office (1968-70), as well as the drafting of constitutional revisions in 1971 that allowed a slight liberalization of the Dictatorship, gave the opposition more room for activity, and decentrali zed authority in the overseas provinces (colonies). Always aware of the complexity of Portugal's colonial problems and of the ongoing wars, Caetano made several visits to Africa as premier, and he sought to implement reforms in social and economic affairs while maintaining the expensive, divisive military effort, Portugal's largest armed forces mobilization in her history.Opposed by intransigent right-wing forces in various sectors in both Portugal and Africa, Caetano's modest "opening" of 1968-70 soon narrowed. Conservative forces in the military, police, civil service, and private sectors opposed key political reforms, including greater democratization, while pursuing the military solution to the African crisis and personal wealth. A significant perspective on Caetano's failed program of reforms, which could not prevent the advent of a creeping revolution in society, is a key development in the 1961-74 era of colonial wars: despite Lisbon's efforts, the greater part of Portuguese emigration and capital investment during this period were directed not to the African colonies but to Europe, North America, and Brazil.Prime Minister Caetano, discouraged by events and by opposition to his reforms from the so-called "Rheumatic Brigade" of superannuated regime loyalists, attempted to resign his office, but President Américo Tomás convinced him to remain. The publication and public reception of African hero General Antônio Spinola's best-selling book Portugal e Futuro (Portugal and the Future) in February 1974 convinced the surprised Caetano that a coup and revolution were imminent. When the virtually bloodless, smoothly operating military coup was successful in what became known as the Revolution of 25 April 1974, Caetano surrendered to the Armed Forces Movement in Lisbon and was flown to Madeira Island and later to exile in Brazil, where he remained for the rest of his life. In his Brazilian exile, Caetano was active writing important memoirs and histories of the Estado Novo from his vantage point, teaching law at a private university in Rio de Janeiro, and carrying on a lively correspondence with persons in Portugal. He died at age 74, in 1980, in Brazil.Historical dictionary of Portugal > Caetano, Marcello José das Neves Alves

117 Brewster, Sir David
SUBJECT AREA: Photography, film and optics[br]b. 11 December 1781 Jedburgh, Roxburghshire, Scotlandd. 10 February 1868 Allerly, Scotland[br]Scottish scientist and popularizer of science, inventor of the kaleidoscope and lenticular stereoscope.[br]Originally destined to follow his father into the Church, Brewster studied divinity at Edinburgh University, where he met many distinguished men of science. He began to take a special interest in optics, and eventually abandoned the clerical profession. In 1813 he presented his first paper to the Royal Society on the properties of light, and within months invented the principle of the kaleidoscope. In 1844 Brewster described a binocular form of Wheatstone's reflecting stereoscope where the mirrors were replaced with lenses or prisms. The idea aroused little interest at the time, but in 1850 a model taken to Paris was brought to the notice of L.J. Duboscq, who immediately began to manufacture Brewster's stereoscope on a large scale; shown at the Great Exhibition of 1851, it attracted the attention of Queen Victoria. Stereoscopic photography rapidly became one of the fashionable preoccupations of the day arid did much to popularize photography. Although originally marketed as a scientific toy and drawing-room pastime, stereoscopy later found scientific application in such fields as microscopy, photogrammetry and radiography. Brewster was a prolific scientific author throughout his life. His income was derived mainly from his writing and he was one of the nineteenth century's most distinguished popularizers of science.[br]Principal Honours and DistinctionsKnighted 1832.

118 MacCready, Paul
SUBJECT AREA: Aerospace[br]b. 29 September 1925 New Haven, Connecticut, USA[br]American designer of man-powered aeroplanes, one of which flew across the English Channel in 1979.[br]As a boy, Paul MacCready was an enthusiastic builder of flying model aeroplanes; he became US National Junior Champion in 1941. He learned to fly and became a pilot with the US Navy in 1943. he developed an interest in gliding in 1945 and became National Soaring Champion in 1948 and 1949. After graduating from the California Institute of Technology (Cal Tech) as a meteorologist, he set up Meteorological Research Inc. In 1953 MacCready became the first American to win the World Gliding Championship. When hang-gliders became popular in the early 1970s MacCready studied their performance and compared them with soaring birds: he came to the conclusion that man-powered flight was a possibility. In an effort to generate an interest in man-powered flight, a cash prize had been offered in Britain by Henry Kremer, a wealthy industrialist and fitness enthusiast. A man-powered aircraft had to complete a one-mile (1.6km) figure-of-eight course in order to win. However, the figure-of-eight proved to be a major obstacle and the prize money was increased over the years to £50,000. In 1976 MacCready and his friend Dr Peter Lissaman set to work on their computer and came up with their optimum design for a man-powered aircraft. The Gossamer Condor had a wing span of 96 ft (27.4 m), about the same as a Douglas DC-9 airliner, yet it weighed just 70 lb (32 kg). It was a tail-first design with a pedaldriven pusher propeller just behind the pilot. Bryan Allen, a biologist, pilot and racing cyclist, joined the team to provide the muscle-power. After over two hundred flights they were ready to make an attempt on the prize, and on 23 August 1977 they succeeded where many had failed, in 7 minutes. Kremer then offered £100,000 for the first manpowered flight across the English Channel. Many thought this would be impossible, but MacCready and his team set about the task of designing a new machine based on their Condor, which they called the Gossamer Albatross. Bryan Allen also had a major task: getting fit for a flight which might take three hours of pedalling. The weather was more of a problem than in California, and after a long delay the Gossamer Albatross took off, on 12 June 1979. After pedalling for 2 hours 49 minutes, Bryan Allen landed in France: it was seventy years since Blériot's flight, although Blériot was much quicker.[br]Principal Honours and DistinctionsWorld Gliding Champion 1953.Bibliography1979, "The Channel crossing and the future", Man Powered Aircraft Symposium, London: Royal Aeronautical Society.Further ReadingM.Grosser, 1981, Gossamer Odyssey, London (provides a brief biography and detailed accounts of the two aircraft).M.F.Jerram, 1980, Incredible Flying Machines, London (a short survey of pedal planes).Articles by Ron Moulton on the Gossamer Albatross appeared in Aerospace (Royal Aeronautical Society) London, August/September 1979, and the Aeromodeller, London, September 1979.JDS -
119 Watt, James
SUBJECT AREA: Steam and internal combustion engines[br]b. 19 January 1735 Greenock, Renfrewshire, Scotlandd. 19 August 1819 Handsworth Heath, Birmingham, England[br]Scottish engineer and inventor of the separate condenser for the steam engine.[br]The sixth child of James Watt, merchant and general contractor, and Agnes Muirhead, Watt was a weak and sickly child; he was one of only two to survive childhood out of a total of eight, yet, like his father, he was to live to an age of over 80. He was educated at local schools, including Greenock Grammar School where he was an uninspired pupil. At the age of 17 he was sent to live with relatives in Glasgow and then in 1755 to London to become an apprentice to a mathematical instrument maker, John Morgan of Finch Lane, Cornhill. Less than a year later he returned to Greenock and then to Glasgow, where he was appointed mathematical instrument maker to the University and was permitted in 1757 to set up a workshop within the University grounds. In this position he came to know many of the University professors and staff, and it was thus that he became involved in work on the steam engine when in 1764 he was asked to put in working order a defective Newcomen engine model. It did not take Watt long to perceive that the great inefficiency of the Newcomen engine was due to the repeated heating and cooling of the cylinder. His idea was to drive the steam out of the cylinder and to condense it in a separate vessel. The story is told of Watt's flash of inspiration as he was walking across Glasgow Green one Sunday afternoon; the idea formed perfectly in his mind and he became anxious to get back to his workshop to construct the necessary apparatus, but this was the Sabbath and work had to wait until the morrow, so Watt forced himself to wait until the Monday morning.Watt designed a condensing engine and was lent money for its development by Joseph Black, the Glasgow University professor who had established the concept of latent heat. In 1768 Watt went into partnership with John Roebuck, who required the steam engine for the drainage of a coal-mine that he was opening up at Bo'ness, West Lothian. In 1769, Watt took out his patent for "A New Invented Method of Lessening the Consumption of Steam and Fuel in Fire Engines". When Roebuck went bankrupt in 1772, Matthew Boulton, proprietor of the Soho Engineering Works near Birmingham, bought Roebuck's share in Watt's patent. Watt had met Boulton four years earlier at the Soho works, where power was obtained at that time by means of a water-wheel and a steam engine to pump the water back up again above the wheel. Watt moved to Birmingham in 1774, and after the patent had been extended by Parliament in 1775 he and Boulton embarked on a highly profitable partnership. While Boulton endeavoured to keep the business supplied with capital, Watt continued to refine his engine, making several improvements over the years; he was also involved frequently in legal proceedings over infringements of his patent.In 1794 Watt and Boulton founded the new company of Boulton \& Watt, with a view to their retirement; Watt's son James and Boulton's son Matthew assumed management of the company. Watt retired in 1800, but continued to spend much of his time in the workshop he had set up in the garret of his Heathfield home; principal amongst his work after retirement was the invention of a pantograph sculpturing machine.James Watt was hard-working, ingenious and essentially practical, but it is doubtful that he would have succeeded as he did without the business sense of his partner, Matthew Boulton. Watt coined the term "horsepower" for quantifying the output of engines, and the SI unit of power, the watt, is named in his honour.[br]Principal Honours and DistinctionsFRS 1785.

120 Logic
My initial step... was to attempt to reduce the concept of ordering in a sequence to that of logical consequence, so as to proceed from there to the concept of number. To prevent anything intuitive from penetrating here unnoticed, I had to bend every effort to keep the chain of inference free of gaps. In attempting to comply with this requirement in the strictest possible way, I found the inadequacy of language to be an obstacle. (Frege, 1972, p. 104)I believe I can make the relation of my 'conceptual notation' to ordinary language clearest if I compare it to the relation of the microscope to the eye. The latter, because of the range of its applicability and because of the ease with which it can adapt itself to the most varied circumstances, has a great superiority over the microscope. Of course, viewed as an optical instrument it reveals many imperfections, which usually remain unnoticed only because of its intimate connection with mental life. But as soon as scientific purposes place strong requirements upon sharpness of resolution, the eye proves to be inadequate.... Similarly, this 'conceptual notation' is devised for particular scientific purposes; and therefore one may not condemn it because it is useless for other purposes. (Frege, 1972, pp. 104-105)To sum up briefly, it is the business of the logician to conduct an unceasing struggle against psychology and those parts of language and grammar which fail to give untrammeled expression to what is logical. He does not have to answer the question: How does thinking normally take place in human beings? What course does it naturally follow in the human mind? What is natural to one person may well be unnatural to another. (Frege, 1979, pp. 6-7)We are very dependent on external aids in our thinking, and there is no doubt that the language of everyday life-so far, at least, as a certain area of discourse is concerned-had first to be replaced by a more sophisticated instrument, before certain distinctions could be noticed. But so far the academic world has, for the most part, disdained to master this instrument. (Frege, 1979, pp. 6-7)There is no reproach the logician need fear less than the reproach that his way of formulating things is unnatural.... If we were to heed those who object that logic is unnatural, we would run the risk of becoming embroiled in interminable disputes about what is natural, disputes which are quite incapable of being resolved within the province of logic. (Frege, 1979, p. 128)[L]inguists will be forced, internally as it were, to come to grips with the results of modern logic. Indeed, this is apparently already happening to some extent. By "logic" is not meant here recursive function-theory, California model-theory, constructive proof-theory, or even axiomatic settheory. Such areas may or may not be useful for linguistics. Rather under "logic" are included our good old friends, the homely locutions "and," "or," "if-then," "if and only if," "not," "for all x," "for some x," and "is identical with," plus the calculus of individuals, event-logic, syntax, denotational semantics, and... various parts of pragmatics.... It is to these that the linguist can most profitably turn for help. These are his tools. And they are "clean tools," to borrow a phrase of the late J. L. Austin in another context, in fact, the only really clean ones we have, so that we might as well use them as much as we can. But they constitute only what may be called "baby logic." Baby logic is to the linguist what "baby mathematics" (in the phrase of Murray Gell-Mann) is to the theoretical physicist-very elementary but indispensable domains of theory in both cases. (Martin, 1969, pp. 261-262)There appears to be no branch of deductive inference that requires us to assume the existence of a mental logic in order to do justice to the psychological phenomena. To be logical, an individual requires, not formal rules of inference, but a tacit knowledge of the fundamental semantic principle governing any inference; a deduction is valid provided that there is no way of interpreting the premises correctly that is inconsistent with the conclusion. Logic provides a systematic method for searching for such counter-examples. The empirical evidence suggests that ordinary individuals possess no such methods. (Johnson-Laird, quoted in Mehler, Walker & Garrett, 1982, p. 130)The fundamental paradox of logic [that "there is no class (as a totality) of those classes which, each taken as a totality, do not belong to themselves" (Russell to Frege, 16 June 1902, in van Heijenoort, 1967, p. 125)] is with us still, bequeathed by Russell-by way of philosophy, mathematics, and even computer science-to the whole of twentieth-century thought. Twentieth-century philosophy would begin not with a foundation for logic, as Russell had hoped in 1900, but with the discovery in 1901 that no such foundation can be laid.
