  • 41 Huygens, Christiaan

    SUBJECT AREA: Horology
    [br]
    b. 14 April 1629 The Hague, the Netherlands
    d. 8 June 1695 The Hague, the Netherlands
    [br]
    Dutch scientist who was responsible for two of the greatest advances in horology: the successful application of both the pendulum to the clock and the balance spring to the watch.
    [br]
    Huygens was born into a cultured and privileged class. His father, Constantijn, was a poet and statesman who had wide interests. Constantijn exerted a strong influence on his son, who was educated at home until he reached the age of 16. Christiaan studied law and mathematics at Ley den University from 1645 to 1647, and continued his studies at the Collegium Arausiacum in Breda until 1649. He then lived at The Hague, where he had the means to devote his time entirely to study. In 1666 he became a Member of the Académie des Sciences in Paris and settled there until his return to The Hague in 1681. He also had a close relationship with the Royal Society and visited London on three occasions, meeting Newton on his last visit in 1689. Huygens had a wide range of interests and made significant contributions in mathematics, astronomy, optics and mechanics. He also made technical advances in optical instruments and horology.
    Despite the efforts of Burgi there had been no significant improvement in the performance of ordinary clocks and watches from their inception to Huygens's time, as they were controlled by foliots or balances which had no natural period of oscillation. The pendulum appeared to offer a means of improvement as it had a natural period of oscillation that was almost independent of amplitude. Galileo Galilei had already pioneered the use of a freely suspended pendulum for timing events, but it was by no means obvious how it could be kept swinging and used to control a clock. Towards the end of his life Galileo described such a. mechanism to his son Vincenzio, who constructed a model after his father's death, although it was not completed when he himself died in 1642. This model appears to have been copied in Italy, but it had little influence on horology, partly because of the circumstances in which it was produced and possibly also because it differed radically from clocks of that period. The crucial event occurred on Christmas Day 1656 when Huygens, quite independently, succeeded in adapting an existing spring-driven table clock so that it was not only controlled by a pendulum but also kept it swinging. In the following year he was granted a privilege or patent for this clock, and several were made by the clockmaker Salomon Coster of The Hague. The use of the pendulum produced a dramatic improvement in timekeeping, reducing the daily error from minutes to seconds, but Huygens was aware that the pendulum was not truly isochronous. This error was magnified by the use of the existing verge escapement, which made the pendulum swing through a large arc. He overcame this defect very elegantly by fitting cheeks at the pendulum suspension point, progressively reducing the effective length of the pendulum as the amplitude increased. Initially the cheeks were shaped empirically, but he was later able to show that they should have a cycloidal shape. The cheeks were not adopted universally because they introduced other defects, and the problem was eventually solved more prosaically by way of new escapements which reduced the swing of the pendulum. Huygens's clocks had another innovatory feature: maintaining power, which kept the clock going while it was being wound.
    Pendulums could not be used for portable timepieces, which continued to use balances despite their deficiencies. Robert Hooke was probably the first to apply a spring to the balance, but his efforts were not successful. From his work on the pendulum Huygens was well aware of the conditions necessary for isochronism in a vibrating system, and in January 1675, with a flash of inspiration, he realized that this could be achieved by controlling the oscillations of the balance with a spiral spring, an arrangement that is still used in mechanical watches. The first model was made for Huygens in Paris by the clockmaker Isaac Thuret, who attempted to appropriate the invention and patent it himself. Huygens had for many years been trying unsuccessfully to adapt the pendulum clock for use at sea (in order to determine longitude), and he hoped that a balance-spring timekeeper might be better suited for this purpose. However, he was disillusioned as its timekeeping proved to be much more susceptible to changes in temperature than that of the pendulum clock.

  • 45 Newcomen, Thomas

    [br]
    b. January or February 1663 Dartmouth, Devon, England
    d. 5 August 1729 London, England
    [br]
    English inventor and builder of the world's first successful stationary steam-engine.
    [br]
    Newcomen was probably born at a house on the quay at Dartmouth, Devon, England, the son of Elias Newcomen and Sarah Trenhale. Nothing is known of his education, and there is only dubious evidence of his apprenticeship to an ironmonger in Exeter. He returned to Dartmouth and established himself there as an "ironmonger". The term "ironmonger" at that time meant more than a dealer in ironmongery: a skilled craftsman working in iron, nearer to today's "blacksmith". In this venture he had a partner, John Calley or Caley, who was a plumber and glazier. Besides running his business in Dartmouth, it is evident that Newcomen spent a good deal of time travelling round the mines of Devon and Cornwall in search of business.
    Eighteenth-century writers and others found it impossible to believe that a provincial ironmonger could have invented the steam-engine, the concept of which had occupied the best scientific brains in Europe, and postulated a connection between Newcomen and Savery or Papin, but scholars in recent years have failed to find any evidence of this. Certainly Savery was in Dartmouth at the same time as Newcomen but there is nothing to indicate that they met, although it is possible. The most recent biographer of Thomas Newcomen is of the opinion that he was aware of Savery and his work, that the two men had met by 1705 and that, although Newcomen could have taken out his own patent, he could not have operated his own engines without infringing Savery's patent. In the event, they came to an agreement by which Newcomen was enabled to sell his engines under Savery's patent.
    The first recorded Newcomen engine is dated 1712, although this may have been preceded by a good number of test engines built at Dartmouth, possibly following a number of models. Over one hundred engines were built to Newcomen's design during his lifetime, with the first engine being installed at the Griff Colliery near Dudley Castle in Staffordshire.
    On the death of Thomas Savery, on 15 May 1715, a new company, the Proprietors of the Engine Patent, was formed to carry on the business. The Company was represented by Edward Elliot, "who attended the Sword Blade Coffee House in Birchin Lane, London, between 3 and 5 o'clock to receive enquiries and to act as a contact for the committee". Newcomen was, of course, a member of the Proprietors.
    A staunch Baptist, Newcomen married Hannah Waymouth, who bore him two sons and a daughter. He died, it is said of a fever, in London on 5 August 1729 and was buried at Bunhill Fields.

    SUBJECT AREA: Paper and printing
    [br]
    b. c. 1394–9 Mainz, Germany
    d. 3 February 1468 Mainz, Germany
    [br]
    German inventor of printing with movable type.
    [br]
    Few biographical details are known of Johann Gensfleisch zum Gutenberg, yet it has been said that he was responsible for Germany's most notable contribution to civilization. He was a goldsmith by trade, of a patrician family of the city of Mainz. He seems to have begun experiments on printing while a political exile in Strasbourg c. 1440. He returned to Mainz between 1444 and 1448 and continued his experiments, until by 1450 he had perfected his invention sufficiently to justify raising capital for its commercial exploitation.
    Circumstances were propitious for the invention of printing at that time. Rises in literacy and prosperity had led to the formation of a social class with the time and resources to develop a taste for reading, and the demand for reading matter had outstripped the ability of the scribes to satisfy it. The various technologies required were well established, and finally the flourishing textile industry was producing enough waste material, rag, to make paper, the only satisfactory and cheap medium for printing. There were others working along similar lines, but it was Gutenberg who achieved the successful adaptation and combination of technologies to arrive at a process by which many identical copies of a text could be produced in a wide variety of forms, of which the book was the most important. Gutenberg did make several technical innovations, however. The two-piece adjustable mould for casting types of varying width, from T to "M", was ingenious. Then he had to devise an oil-based ink suitable for inking metal type, derived from the painting materials developed by contemporary Flemish artists. Finally, probably after many experiments, he arrived at a metal alloy of distinctive composition suitable for casting type.
    In 1450 Gutenberg borrowed 800 guldens from Johannes Fust, a lawyer of Mainz, and two years later Fust advanced a further 800 guldens, securing for himself a partnership in Gutenberg's business. But in 1455 Fust foreclosed and the bulk of Gutenberg's equipment passed to Peter Schöffer, who was in the service of Fust and later married his daughter. Like most early printers, Gutenberg seems not to have appreciated, or at any rate to have been able to provide for, the great dilemma of the publishing trade, namely the outlay of considerable capital in advance of each publication and the slowness of the return. Gutenberg probably retained only the type for the 42- and 36-line bibles and possibly the Catholicon of 1460, an encyclopedic work compiled in the thirteenth century and whose production pointed the way to printing's role as a means of spreading knowledge. The work concluded with a short descriptive piece, or colophon, which is probably by Gutenberg himself and is the only output of his mind that we have; it manages to omit the names of both author and printer.
    Gutenberg seems to have abandoned printing after 1460, perhaps due to failing eyesight as well as for financial reasons, and he suffered further loss in the sack of Mainz in 1462. He received a kind of pension from the Archbishop in 1465, and on his death was buried in the Franciscan church in Mainz. The only major work to have issued for certain from Gutenberg's workshop is the great 42-line bible, begun in 1452 and completed by August 1456. The quality of this Graaf piece of printing is a tribute to Gutenberg's ability as a printer, and the soundness of his invention is borne out by the survival of the process as he left it to the world, unchanged for over three hundred years save in minor details.

    arc-resistant switchgear
    A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.

    There are three classes of protection:
    Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
    Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
    Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.

    Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.

    arc-proof switchgear
    An incorrect term. Please refer to arc-resistant switchgear

    Параллельные тексты EN-RU

    If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.

    Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.

    The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.

    Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.

    This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.

    Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
    1. assemblies mechanically capable of withstanding the electric arc (passive protection)
    2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
    3. assemblies equipped with current limiting circuitbreakers.

    These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.

    As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.

    This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.

    Кроме того, под воздействием дуги различные материалы разлагаются на продукты, имеющие высокую температуру, в том числе газы и дым, которые почти всегда вырываются из оболочки НКУ под высоким давлением, подвергая опасности оперативный персонал.

    Европейская директива 2006/95/EC определяет основные требования безопасности для низковольтного (от 50 до 1000 В переменного тока и от 75 до 1500 В постоянного тока) оборудования поставляемого на рынок Европейского Сообщества.

    Одно из основных требований безопасности, определяемое данной директивой как наиболее важное, заключается в необходимости предпринять технические меры для предотвращения "подъема температуры, возникновения электрической дуги или излучения", которые могут причинить ущерб.

    Данная проблема всегда учитывалась при создании различных аппаратов, но незаслуженно игнорировалась при разработке электрических комплектных устройств, и только в последние 10-15 лет ей стали уделять должное внимание как в Италии, так и во всем мире.

    При возникновении электрической дуги внутри НКУ безопасность оператора и электроустановки обеспечивается тремя способами:
    1. Конструкция НКУ должна выдерживать механические воздействия, возникающие при горении электрической дуги (пассивная защита).
    2. НКУ должно быть оснащено устройствами, ограничивающими воздействие электрической дуги (активная защита)
    3. НКУ должны быть оснащены токоограничивающими автоматическими выключателями.

    Указанные три способа (применяемые совместно) получили дальнейшее развитие в промышленности и успешно применяются основными изготовителями НКУ распределения и управления.

    Как будет показано далее при рассмотрении первых двух способов, активная защита от дуговых» неисправностей является более сложной, чем пассивная защита.

    Это объясняется необходимостью использования дополнительных электромеханических или электронных устройств, задачей которых является ограничение воздействий дуги и которые сами могут оказаться неисправными и не сработать.

    arc-resistant switchgear
    A type of switchgear design which is designed to withstand the effects of an internal arcing fault, without causing harm to personnel who are located in defined areas. It is not intended to withstand these internal arcing fault without possibly causing physical damage to the structure and/or components, but often the physical damage is less with an arc-resistant design.

    There are three classes of protection:
    Type A - eliminates the emission of gases and particles from the front of the switchgear during an internal arcing fault,
    Type B - eliminates the emission of gases and particles from the front and sides of the switchgear during an internal arcing fault,
    Type C - eliminates the emission of gases and particles from the front and sides of the switchgear, from between compartments within the same cell, and between adjacent cells during an internal arcing fault.

    Arc-resistant switchgear has traditionally been metal-clad, but the basic concept could also be applied to other types of switchgear as well.

    If the electric arc occurs inside LV switchgear it generates internal overpressures and results in local overheatings which may cause high mechanical and thermal stresses in the equipment.

    Besides, the involved materials can generate hot decomposition products, gases or fumes, which, due to the overpressure, are almost always ejected to the outside of the enclosure thus jeopardizing the operator safety.

    The European Directive 2006/95/EC states the fundamental safety requirements for low voltage electric materials (from 50 V to 1000 V in alternating current, from 75 V to 1500 V in continuos current) to be put on the market within the European Community.

    Among the essential safety requirements defined by this Directive particular importance is given to the need of taking technical measures to prevent “temperature rises, electric arcs or radiations which may result in hazards” from occurring.

    This aspect has always been highly considered for apparatus, but it has been wrongly neglected for electrical switchgear and only in the last 10-15 years it has been catching on both at Italian as well as at international level.

    Safety for the operator and for the installation in case of arcing inside LV switchgear can be obtained through three different design philosophies:
    1. assemblies mechanically capable of withstanding the electric arc (passive protection)
    2. assemblies equipped with devices limiting the effects of internal arcing (active protection)
    3. assemblies equipped with current limiting circuitbreakers.

    These three solutions (also combined together) have found a remakable development in the industrial field and have been successfully applied by the main manufacturers of LV switchgear and controlgear assemblies.

    As it can be seen hereafter by examining the first two solutions, an “active” protection against arc faults is intrinsecally more complex than a “passive” one.

    This because of the presence of additional electromechanical/ electronic devices5 which limit the arcing effects and which, by their nature, may be subject to faults or not-tripping.

    2. НКУ должно быть оснащено устройствами, ограничивающими воздействие электрической дуги (активная защита)
    3. НКУ должны быть оснащены токоограничивающими автоматическими выключателями.

    Указанные три способа (применяемые совместно) получили дальнейшее развитие в промышленности и успешно применяются основными изготовителями НКУ распределения и управления.

    Как будет показано далее при рассмотрении первых двух способов, активная защита от дуговых» неисправностей является более сложной, чем пассивная защита.

    Это объясняется необходимостью использования дополнительных электромеханических или электронных устройств, задачей которых является ограничение воздействий дуги и которые сами могут оказаться неисправными и не сработать.

  • 55 Paul, Lewis

    SUBJECT AREA: Textiles
    [br]
    d. April 1759 Brook Green, London, England
    [br]
    English inventor of hand carding machines and partner with Wyatt in early spinning machines.
    [br]
    Lewis Paul, apparently of French Huguenot extraction, was quite young when his father died. His father was Physician to Lord Shaftsbury, who acted as Lewis Paul's guardian. In 1728 Paul made a runaway match with a widow and apparently came into her property when she died a year later. He must have subsequently remarried. In 1732 he invented a pinking machine for making the edges of shrouds out of which he derived some profit.
    Why Paul went to Birmingham is unknown, but he helped finance some of Wyatt's earlier inventions. Judging by the later patents taken out by Paul, it is probable that he was the one interested in spinning, turning to Wyatt for help in the construction of his spinning machine because he had no mechanical skills. The two men may have been involved in this as early as 1733, although it is more likely that they began this work in 1735. Wyatt went to London to construct a model and in 1736 helped to apply for a patent, which was granted in 1738 in the name of Paul. The patent shows that Paul and Wyatt had a number of different ways of spinning in mind, but contains no drawings of the machines. In one part there is a description of sets of rollers to draw the cotton out more finely that could have been similar to those later used by Richard Arkwright. However, it would seem that Paul and Wyatt followed the other main method described, which might be called spindle drafting, where the fibres are drawn out between the nip of a pair of rollers and the tip of the spindle; this method is unsatisfactory for continuous spinning and results in an uneven yarn.
    The spinning venture was supported by Thomas Warren, a well-known Birmingham printer, Edward Cave of Gentleman's Magazine, Dr Robert James of fever-powder celebrity, Mrs Desmoulins, and others. Dr Samuel Johnson also took much interest. In 1741 a mill powered by two asses was equipped at the Upper Priory, Birmingham, with, machinery for spinning cotton being constructed by Wyatt. Licences for using the invention were sold to other people including Edward Cave, who established a mill at Northampton, so the enterprise seemed to have great promise. A spinning machine must be supplied with fibres suitably prepared, so carding machines had to be developed. Work was in hand on one in 1740 and in 1748 Paul took out another patent for two types of carding device, possibly prompted by the patent taken out by Daniel Bourn. Both of Paul's devices were worked by hand and the carded fibres were laid onto a strip of paper. The paper and fibres were then rolled up and placed in the spinning machine. In 1757 John Dyer wrote a poem entitled The Fleece, which describes a circular spinning machine of the type depicted in a patent taken out by Paul in 1758. Drawings in this patent show that this method of spinning was different from Arkwright's. Paul endeavoured to have the machine introduced into the Foundling Hospital, but his death in early 1759 stopped all further development. He was buried at Paddington on 30 April that year.

  • 56 Creativity

       Put in this bald way, these aims sound utopian. How utopian they areor rather, how imminent their realization-depends on how broadly or narrowly we interpret the term "creative." If we are willing to regard all human complex problem solving as creative, then-as we will point out-successful programs for problem solving mechanisms that simulate human problem solvers already exist, and a number of their general characteristics are known. If we reserve the term "creative" for activities like discovery of the special theory of relativity or the composition of Beethoven's Seventh Symphony, then no example of a creative mechanism exists at the present time. (Simon, 1979, pp. 144-145)
       Among the questions that can now be given preliminary answers in computational terms are the following: how can ideas from very different sources be spontaneously thought of together? how can two ideas be merged to produce a new structure, which shows the influence of both ancestor ideas without being a mere "cut-and-paste" combination? how can the mind be "primed," so that one will more easily notice serendipitous ideas? why may someone notice-and remember-something fairly uninteresting, if it occurs in an interesting context? how can a brief phrase conjure up an entire melody from memory? and how can we accept two ideas as similar ("love" and "prove" as rhyming, for instance) in respect of a feature not identical in both? The features of connectionist AI models that suggest answers to these questions are their powers of pattern completion, graceful degradation, sensitization, multiple constraint satisfaction, and "best-fit" equilibration.... Here, the important point is that the unconscious, "insightful," associative aspects of creativity can be explained-in outline, at least-by AI methods. (Boden, 1996, p. 273)
       There thus appears to be an underlying similarity in the process involved in creative innovation and social independence, with common traits and postures required for expression of both behaviors. The difference is one of product-literary, musical, artistic, theoretical products on the one hand, opinions on the other-rather than one of process. In both instances the individual must believe that his perceptions are meaningful and valid and be willing to rely upon his own interpretations. He must trust himself sufficiently that even when persons express opinions counter to his own he can proceed on the basis of his own perceptions and convictions. (Coopersmith, 1967, p. 58)
       he average level of ego strength and emotional stability is noticeably higher among creative geniuses than among the general population, though it is possibly lower than among men of comparable intelligence and education who go into administrative and similar positions. High anxiety and excitability appear common (e.g. Priestley, Darwin, Kepler) but full-blown neurosis is quite rare. (Cattell & Butcher, 1970, p. 315)
       he insight that is supposed to be required for such work as discovery turns out to be synonymous with the familiar process of recognition; and other terms commonly used in the discussion of creative work-such terms as "judgment," "creativity," or even "genius"-appear to be wholly dispensable or to be definable, as insight is, in terms of mundane and well-understood concepts. (Simon, 1989, p. 376)
       From the sketch material still in existence, from the condition of the fragments, and from the autographs themselves we can draw definite conclusions about Mozart's creative process. To invent musical ideas he did not need any stimulation; they came to his mind "ready-made" and in polished form. In contrast to Beethoven, who made numerous attempts at shaping his musical ideas until he found the definitive formulation of a theme, Mozart's first inspiration has the stamp of finality. Any Mozart theme has completeness and unity; as a phenomenon it is a Gestalt. (Herzmann, 1964, p. 28)
       Great artists enlarge the limits of one's perception. Looking at the world through the eyes of Rembrandt or Tolstoy makes one able to perceive aspects of truth about the world which one could not have achieved without their aid. Freud believed that science was adaptive because it facilitated mastery of the external world; but was it not the case that many scientific theories, like works of art, also originated in phantasy? Certainly, reading accounts of scientific discovery by men of the calibre of Einstein compelled me to conclude that phantasy was not merely escapist, but a way of reaching new insights concerning the nature of reality. Scientific hypotheses require proof; works of art do not. Both are concerned with creating order, with making sense out of the world and our experience of it. (Storr, 1993, p. xii)
       The importance of self-esteem for creative expression appears to be almost beyond disproof. Without a high regard for himself the individual who is working in the frontiers of his field cannot trust himself to discriminate between the trivial and the significant. Without trust in his own powers the person seeking improved solutions or alternative theories has no basis for distinguishing the significant and profound innovation from the one that is merely different.... An essential component of the creative process, whether it be analysis, synthesis, or the development of a new perspective or more comprehensive theory, is the conviction that one's judgment in interpreting the events is to be trusted. (Coopersmith, 1967, p. 59)
       In the daily stream of thought these four different stages [preparation; incubation; illumination or inspiration; and verification] constantly overlap each other as we explore different problems. An economist reading a Blue Book, a physiologist watching an experiment, or a business man going through his morning's letters, may at the same time be "incubating" on a problem which he proposed to himself a few days ago, be accumulating knowledge in "preparation" for a second problem, and be "verifying" his conclusions to a third problem. Even in exploring the same problem, the mind may be unconsciously incubating on one aspect of it, while it is consciously employed in preparing for or verifying another aspect. (Wallas, 1926, p. 81)
       he basic, bisociative pattern of the creative synthesis [is] the sudden interlocking of two previously unrelated skills, or matrices of thought. (Koestler, 1964, p. 121)
        11) The Earliest Stages in the Creative Process Involve a Commerce with Disorder
       Even to the creator himself, the earliest effort may seem to involve a commerce with disorder. For the creative order, which is an extension of life, is not an elaboration of the established, but a movement beyond the established, or at least a reorganization of it and often of elements not included in it. The first need is therefore to transcend the old order. Before any new order can be defined, the absolute power of the established, the hold upon us of what we know and are, must be broken. New life comes always from outside our world, as we commonly conceive that world. This is the reason why, in order to invent, one must yield to the indeterminate within him, or, more precisely, to certain illdefined impulses which seem to be of the very texture of the ungoverned fullness which John Livingston Lowes calls "the surging chaos of the unexpressed." (Ghiselin, 1985, p. 4)
       New life comes always from outside our world, as we commonly conceive our world. This is the reason why, in order to invent, one must yield to the indeterminate within him, or, more precisely, to certain illdefined impulses which seem to be of the very texture of the ungoverned fullness which John Livingston Lowes calls "the surging chaos of the unexpressed." Chaos and disorder are perhaps the wrong terms for that indeterminate fullness and activity of the inner life. For it is organic, dynamic, full of tension and tendency. What is absent from it, except in the decisive act of creation, is determination, fixity, and commitment to one resolution or another of the whole complex of its tensions. (Ghiselin, 1952, p. 13)
       [P]sychoanalysts have principally been concerned with the content of creative products, and with explaining content in terms of the artist's infantile past. They have paid less attention to examining why the artist chooses his particular activity to express, abreact or sublimate his emotions. In short, they have not made much distinction between art and neurosis; and, since the former is one of the blessings of mankind, whereas the latter is one of the curses, it seems a pity that they should not be better differentiated....
       Psychoanalysis, being fundamentally concerned with drive and motive, might have been expected to throw more light upon what impels the creative person that in fact it has. (Storr, 1993, pp. xvii, 3)
       A number of theoretical approaches were considered. Associative theory, as developed by Mednick (1962), gained some empirical support from the apparent validity of the Remote Associates Test, which was constructed on the basis of the theory.... Koestler's (1964) bisociative theory allows more complexity to mental organization than Mednick's associative theory, and postulates "associative contexts" or "frames of reference." He proposed that normal, non-creative, thought proceeds within particular contexts or frames and that the creative act involves linking together previously unconnected frames.... Simonton (1988) has developed associative notions further and explored the mathematical consequences of chance permutation of ideas....
       Like Koestler, Gruber (1980; Gruber and Davis, 1988) has based his analysis on case studies. He has focused especially on Darwin's development of the theory of evolution. Using piagetian notions, such as assimilation and accommodation, Gruber shows how Darwin's system of ideas changed very slowly over a period of many years. "Moments of insight," in Gruber's analysis, were the culminations of slow long-term processes.... Finally, the information-processing approach, as represented by Simon (1966) and Langley et al. (1987), was considered.... [Simon] points out the importance of good problem representations, both to ensure search is in an appropriate problem space and to aid in developing heuristic evaluations of possible research directions.... The work of Langley et al. (1987) demonstrates how such search processes, realized in computer programs, can indeed discover many basic laws of science from tables of raw data.... Boden (1990a, 1994) has stressed the importance of restructuring the problem space in creative work to develop new genres and paradigms in the arts and sciences. (Gilhooly, 1996, pp. 243-244; emphasis in original)

  • 60 Fourdrinier, Henry

    SUBJECT AREA: Paper and printing
    [br]
    b. 11 February 1766 London, England
    d. 3 September 1854 Mavesyn Ridware, near Rugeley, Staffordshire, England
    [br]
    English pioneer of the papermaking machine.
    [br]
    Fourdrinier's father was a paper manufacturer and stationer of London, from a family of French Protestant origin. Henry took up the same trade and, with his brother Sealy (d. 1847), devoted many years to developing the papermaking machine. Their first patent was taken out in 1801, but success was still far off. A machine for making paper had been invented a few years previously by Nicolas Robert at the Didot's mill at Essonnes, south of Paris. Robert quarrelled with the Didots, who then contacted their brother-in-law in England, John Gamble, in an attempt to raise capital for a larger machine. Gamble and the Fourdriniers called in the engineer Bryan Donkin, and between them they patented a much improved machine in 1807. In the new machine, the paper pulp flowed on to a moving continuous woven wire screen and was then squeezed between rollers to remove much of the water. The paper thus formed was transferred to a felt blanket and passed through a second press to remove more water, before being wound while still wet on to a drum. For the first time, a continuous sheet of paper could be made. Other inventors soon made further improvements: in 1817 John Dickinson obtained a patent for sizing baths to improve the surface of the paper; while in 1820 Thomas Crompton patented a steam-heated drum round which the paper was passed to speed up the drying process. The development cost of £60,000 bankrupted the brothers. Although Parliament extended the patent for fourteen years, and the machine was widely adopted, they never reaped much profit from it. Tsar Alexander of Russia became interested in the papermaking machine while on a visit to England in 1814 and promised Henry Fourdrinier £700 per year for ten years for super-intending the erection of two machines in Russia; Henry carried out the work, but he received no payment. At the age of 72 he travelled to St Petersburg to seek recompense from the Tsar's successor Nicholas I, but to no avail. Eventually, on a motion in the House of Commons, the British Government awarded Fourdrinier a payment of £7,000. The paper trade, sensing the inadequacy of this sum, augmented it with a further sum which they subscribed so that an annuity could be purchased for Henry, then the only surviving brother, and his two daughters, to enable them to live in modest comfort. From its invention in ancient China (see Cai Lun), its appearance in the Middle Ages in Europe and through the first three and a half centuries of printing, every sheet of paper had to made by hand. The daily output of a hand-made paper mill was only 60–100 lb (27–45 kg), whereas the new machine increased that tenfold. Even higher speeds were achieved, with corresponding reductions in cost; the old mills could not possibly have kept pace with the new mechanical printing presses. The Fourdrinier machine was thus an essential element in the technological developments that brought about the revolution in the production of reading matter of all kinds during the nineteenth century. The high-speed, giant paper-making machines of the late twentieth century work on the same principle as the Fourdrinier of 1807.
