The descendant of a French refugee, Achard began the systematic study of beet on his estate at Caulsdorf in 1786. The work had been stimulated by the discovery in 1747 of the presence of sugar in fodder beet. This research had been carried out by Andreas Marggraf, under whom Franz Achard trained. After a fire destroyed his laboratories Achard established himself on the domain of Französisch in Buchholtz near Berlin.

After thirteen years of study he felt sufficiently confident to apply for an interview with Frederick William III, King of Prussia, which took place on 11 January 1799. Achard presented the King with a loaf of sugar made from raw beet by his Sugar Boiling House method. He requested a ten-year monopoly on his idea, as well as the grant of land on which to carry out his work. The King was sufficiently impressed to establish a committee to supervise further trials, and asked Achard to make a public statement on his work. The King ordered a factory to be built at his own expense, and paid Achard a salary to manage it. In 1801 he was granted the domain of Cunern in Silesia; he built his first sugar factory there and began production in 1802. Unfortunately Achard's business skills were negligible, and he was bankrupt within the year. In 1810 the State relieved him of his debt and gave him a pension, and in 1812 the first sugar factory was turned into a school of sugar technology.

He studied in Alexandria, after which he returned to Syracuse where he spent most of the rest of his life. He made many mathematical discoveries, including the most accurate calculation of pi made up to that time. In engineering he was the founder of the science of hydrostatics. He is well known for the discovery of "Archimedes" Law', that a body wholly or partly immersed in a fluid loses weight equal to the weight of the fluid displaced. He thus made the first measurement of specific gravity.

Archimedes also proved the law of the lever and developed the theory of mechanical advantage, boasting to his cousin Hieron, "Give me a place to stand on and with a lever I will move the whole world." To prove his point, he launched one of the biggest ships built up to that date. During his time in Egypt, he devised the "Archimedean Screw", still used today in Middle Eastern countries for pumping water. He also built an astronomical instrument to demonstrate the movements of the heavenly bodies, a form of orrery.

He was General of Ordnance to Heiron, and when the Romans besieged Syracuse, a legionary came across Archimedes drawing geometrical diagrams in the sand. Archimedes immediately told him to 'Keep off and the soldier killed him. He also experimented with burning glasses and mirrors for setting fire to wooden ships.

After graduating in chemistry from the Ecole Polytechnique in 1887, Charpy continued to work there on the physical chemistry of solutions for his doctorate. He joined the Laboratoire d'Artillerie de la Marine in 1892 and began to study the structure and mechanical properties of various steels in relation to their previous heat treatment. His first memoir, on the mechanical properties of steels quenched from various temperatures, was published in 1892 on the advice of Henri Le Chatelier. He joined the Compagnie de Chatillon Commentry Fourchamboult et Decazeville at their steelworks in Imphy in 1898, shortly after the discovery of Invar by G.E. Guillaume. Most of the alloys required for this investigation had been prepared at Imphy, and their laboratories were therefore well equipped with sensitive and refined dilatometric facilities. Charpy and his colleague L.Grenet utilized this technique in many of their earlier investigations, which were largely concerned with the transformation points of steel. He began to study the magnetic characteristics of silicon steels in 1902, shortly after their use as transformer laminations had first been proposed by Hadfield and his colleagues in 1900. Charpy was the first to show that the magnetic hysteresis of these alloys decreased rapidly as their grain size increased.

The first details of Charpy's pendulum impact testing machine were published in 1901, about two years before Izod read his paper to the British Association. As with Izod's machine, the energy of fracture was measured by the retardation of the pendulum. Charpy's test pieces, however, unlike those of Izod, were in the form of centrally notched beams, freely supported at each end against rigid anvils. This arrangement, it was believed, transmitted less energy to the frame of the machine and allowed the energy of fracture to be more accurately measured. In practice, however, the blow of the pendulum in the Charpy test caused visible distortion in the specimen as a whole. Both tests were still widely used in the 1990s.

In 1920 Charpy left Imphy to become Director-General of the Compagnie des Aciéries de la Marine et Homecourt. After his election to the Académie des Sciences in 1918, he came to be associated with Floris Osmond and Henri Le Chatelier as one of the founders of the "French School of Physical Metallurgy". Around the turn of the century he had contributed much to the development of the metallurgical microscope and had helped to introduce the Chatelier thermocouple into the laboratory and to industry. He also popularized the use of platinum-wound resistance furnaces for laboratory purposes. After 1920 his industrial responsibilities increased greatly, although he continued to devote much of his time to teaching at the Ecole Supérieure des Mines in Paris, and at the Ecole Polytechnique. His first book, Leçons de Chimie (1892, Paris), was written at the beginning of his career, in association with H.Gautier. His last, Notions élémentaires de sidérurgie (1946, Paris), with P.Pingault as co-author, was published posthumously.

Guillaume came from a family of clock-and watchmakers. He was educated at the Gymnasium in Neuchâtel and at Zurich Polytechnic, from which he received his doctorate in 1883 for a thesis on electrolytic capacitors. In the same year he joined the International Bureau of Weights and Measures at Sèvres in France, where he was to spend the rest of his working life. He retired as Director in 1936. At the bureau he was involved in distributing the national standards of the metre to countries subscribing to the General Conference on Weights and Measures that had been held in 1889. This made him aware of the crucial effect of thermal expansion on the lengths of the standards and he was prompted to look for alternative materials that would be less costly than the platinum alloys which had been used. While studying nickel steels he made the surprising discovery that the thermal expansion of certain alloy compositions was less than that of the constituent metals. This led to the development of a steel containing about 36 per cent nickel that had a very low thermal coefficient of expansion. This alloy was subsequently named "invar", an abbreviation of invariable. It was well known that changes in temperature affected the timekeeping of clocks by altering the length of the pendulum, and various attempts had been made to overcome this defect, most notably the mercury-compensated pendulum of Graham and the gridiron pendulum of Harrison. However, an invar pendulum offered a simpler and more effective method of temperature compensation and was used almost exclusively for pendulum clocks of the highest precision.

Changes in temperature can also affect the timekeeping of watches and chronometers, but this is due mainly to changes in the elasticity or stiffness of the balance spring rather than to changes in the size of the balance itself. To compensate for this effect Guillaume developed another more complex nickel alloy, "elinvar" (elasticity invariable), whose elasticity remained almost constant with changes in temperature. This had two practical consequences: the construction of watches could be simplified (by using monometallic balances) and more accurate chronometers could be made.

Guinand received little formal education and followed his father's trade of joiner. He specialized in making clock cases, but after learning how to cast metals he took up the more lucrative work of making watch cases. When he was about 20 years old, in a customer's house he caught sight of an English telescope, a rarity in a Swiss mountain village. Intrigued, he obtained permission to examine it. This aroused his interest in optical matters and he began making spectacles and small telescopes.

Achromatic lenses were becoming known, their use being to remove the defect of chromatic aberration or coloured optical images, but there remained defects due to imperfections in the glass itself. Stimulated by offers of prizes by scientific bodies, including the Royal Society of London, for removing these defects, Guinand set out to remedy them. He embarked in 1784 on a long and arduous series of experiments, varying the materials and techniques for making glass. The even more lucrative trade of making bells for repeaters provided the funds for a furnace capable of holding 2 cwt (102 kg) of molten glass. By 1798 or so he had succeeded in making discs of homogeneous glass. He impressed the famous Parisian astronomer de Lalande with them and his glass became well enough known for scientists to visit him. In 1805 Fraunhofer persuaded Guinand to join his optical-instrument works at Benediktheurn, in Bavaria, to make lenses. After nine years, Guinand returned to Brenets with a pension, on condition he made no more glass and disclosed no details of his methods. After two years these conditions had become irksome and he relinquished the pension. On 19 February 1823 Guinand described his discoveries in his classic "Memoir on the making of optical glass, more particularly of glass of high refractive index for use in the production of achromatic lenses", presented to the Société de Physique et d'Histoire Naturelle de Genève. This gives details of his experiments and investigations and discusses a suitable pot-clay stirrer and stirring mechanism for the molten glass, with temperature control, to overcome optical-glass defects such as bubbles, seeds, cords and colours. Guinand was hailed as the man in Europe who had achieved this and has thus rightly been called the founder of the era of optical glassmaking.

He graduated in medicine from Vienna in 1891 and spent the next five years at various European universities. In 1923 he began to work at the Rockefeller Institute for Medical Research in New York. In 1900, while investigating the disintegration of red blood cells, he discovered the reaction of one person's cells to the serum of another. By 1909 he had developed the classification of four main blood groups, which has proved to be of fundamental importance, particularly in relation to the development of blood-transfusion techniques and blood banks, despite the later discovery of many subgroups as well as of the rhesus factor (1940) and its relation to miscarriages and neonatal disease.

He was involved in research in many other fields, including syphilis, thyroid disease, scarlet fever and typhus, but his main studies were centred on the chemistry of immunology and its significance in allergy.

Sobrero initially studied medicine, qualifying as both a physician and surgeon, and then went on to study chemistry in Turin, Paris and Giessen. In 1847 he created nitroglycerine by slowly adding glycerine to a mixture of nitric and sulphuric acids. The explosive injured both him and a number of others in the laboratory, and he was so horrified by its power and its potential effect on warfare that he refused to exploit his discovery; its introduction into general use thus had to wait for Immanuel and Alfred Nobel. In 1849 Sobrero was appointed Professor of Applied Chemistry at the Technical Institute, Turin, and he later became Professor of Pure Chemistry as well. He retired in 1882.

    Birth Order and Ideological Trends

   In science, birth-order effects are driven by the ideological implications inherent in new ideas. Theories that have socially radical implications tend to be championed by laterborns and rejected by firstborns. Theories that have socially conservative implications display the opposite trend: firstborns tend to back conservative innovations, whereas laterborns are among the most vocal opponents of this class of ideas....

   The linear relationship between birth-order trends and ideological tendencies makes my argument about birth order testable in a variety of ways. For example, socially conservative innovations that are championed by laterborns should never occur in history. The discovery of even one such episode with a significant trend would constitute a formidable challenge to my claims. Similarly, evidence of radical revolutions favored by firstborns is also not to be expected. When firstborns have "rebelled" in history, it has been to bring God back into the scientific picture or to reaffirm the social status quo. Firstborns favored eugenics because this reform movement seemed to rationalize socioeconomic disparities in terms of genetics. (The word eugenics comes from the Greek, meaning "well born.") Historically, firstborns have tended to support the notion that biology is destiny. Minority races, women, and laterborns have all typically resisted such deterministic notions. (Sulloway, 1996, pp. 130, 133)

   1) Grammar as Analogous to a Scientific Theory

   I think that the failure to offer a precise account of the notion "grammar" is not just a superficial defect in linguistic theory that can be remedied by adding one more definition. It seems to me that until this notion is clarified, no part of linguistic theory can achieve anything like a satisfactory development.... I have been discussing a grammar of a particular language here as analogous to a particular scientific theory, dealing with its subject matter (the set of sentences of this language) much as embryology or physics deals with its subject matter. (Chomsky, 1964, p. 213)

   2) Native Speakers and Their Grammar

   Obviously, every speaker of a language has mastered and internalized a generative grammar that expresses his knowledge of his language. This is not to say that he is aware of the rules of grammar or even that he can become aware of them, or that his statements about his intuitive knowledge of his language are necessarily accurate. (Chomsky, 1965, p. 8)

   3) The Reduction of Transformation Rules In a Science of Grammar

   Much effort has been devoted to showing that the class of possible transformations can be substantially reduced without loss of descriptive power through the discovery of quite general conditions that all such rules and the representations they operate on and form must meet.... [The] transformational rules, at least for a substantial core grammar, can be reduced to the single rule, "Move alpha" (that is, "move any category anywhere"). (Mehler, Walker & Garrett, 1982, p. 21)

   4) The Relationship of Transformational Grammar to Semantics and to Human Performance

   he implications of assuming a semantic memory for what we might call "generative psycholinguistics" are: that dichotomous judgments of semantic well-formedness versus anomaly are not essential or inherent to language performance; that the transformational component of a grammar is the part most relevant to performance models; that a generative grammar's role should be viewed as restricted to language production, whereas sentence understanding should be treated as a problem of extracting a cognitive representation of a text's message; that until some theoretical notion of cognitive representation is incorporated into linguistic conceptions, they are unlikely to provide either powerful language-processing programs or psychologically relevant theories.

   Although these implications conflict with the way others have viewed the relationship of transformational grammars to semantics and to human performance, they do not eliminate the importance of such grammars to psychologists, an importance stressed in, and indeed largely created by, the work of Chomsky. It is precisely because of a growing interdependence between such linguistic theory and psychological performance models that their relationship needs to be clarified. (Quillian, 1968, p. 260)

   5) The Terminologies of Formal Grammar

   here are some terminological distinctions that are crucial to explain, or else confusions can easily arise. In the formal study of grammar, a language is defined as a set of sentences, possibly infinite, where each sentence is a string of symbols or words. One can think of each sentence as having several representations linked together: one for its sound pattern, one for its meaning, one for the string of words constituting it, possibly others for other data structures such as the "surface structure" and "deep structure" that are held to mediate the mapping between sound and meaning. Because no finite system can store an infinite number of sentences, and because humans in particular are clearly not pullstring dolls that emit sentences from a finite stored list, one must explain human language abilities by imputing to them a grammar, which in the technical sense is a finite rule system, or programme, or circuit design, capable of generating and recognizing the sentences of a particular language. This "mental grammar" or "psychogrammar" is the neural system that allows us to speak and understand the possible word sequences of our native tongue. A grammar for a specific language is obviously acquired by a human during childhood, but there must be neural circuitry that actually carries out the acquisition process in the child, and this circuitry may be called the language faculty or language acquisition device. An important part of the language faculty is universal grammar, an implementation of a set of principles or constraints that govern the possible form of any human grammar. (Pinker, 1996, p. 263)

   6) The Theory of Grammar

   A grammar of language L is essentially a theory of L. Any scientific theory is based on a finite number of observations, and it seeks to relate the observed phenomena and to predict new phenomena by constructing general laws in terms of hypothetical constructs.... Similarly a grammar of English is based on a finite corpus of utterances (observations), and it will contain certain grammatical rules (laws) stated in terms of the particular phonemes, phrases, etc., of English (hypothetical constructs). These rules express structural relations among the sentences of the corpus and the infinite number of sentences generated by the grammar beyond the corpus (predictions). (Chomsky, 1957, p. 49)

   1) The Catalyst to Darwin's Discovery of the Principle of Natural Selection

   In October 1838 that is, fifteen months after I had begun my systematic enquiry, I happened to read for amusement "Malthus on Population," and being well prepared to appreciate the struggle for existence which everywhere goes on from long-continued observation of the habits of animals and plants, it at once struck me that under these circumstances favorable variations would tend to be preserved, and unfavorable ones to be destroyed. (Darwin, 1911, p. 68)

   2) Insight in the Chimpanzee

   The insight of the chimpanzee shows itself to be principally determined by his optical apprehension of the situation. (KoЁhler, 1925, p. 267)

   3) Brevity, Suddenness and Immediate Certainty

   Then I turned my attention to the study of some arithmetical questions apparently without much success and without a suspicion of any connection with my preceding researches. Disgusted with my failure, I went to spend a few days at the seaside, and thought of something else. One morning, walking on the bluff, the idea came to me, with just the same characteristics of brevity, suddenness and immediate certainty, that the arithmetic transformations of indeterminate ternary quadratic forms were identical with those of non-Euclidean geometry. (Poincareґ, 1929, p. 388)

   4) Insight Is Not a Mysterious Mental Agent

   The direct awareness of determination... may also be called insight. When I once used this expression in a description of the intelligent behavior of apes, an unfortunate misunderstanding was, it seems, not entirely prevented.... Apparently, some readers interpreted this formulation as though it referred to a mysterious mental agent or faculty which was made responsible for the apes' behavior. Actually, nothing of this sort was intended... the concept is used in a strictly descriptive fashion. (KoЁhler, 1947, pp. 341-342)

   5) Insight in Animal Problem- Solving

   The task must be neither so easy that the animal solves the problem at once, thus not allowing one to analyze the solution; nor so hard that the animal fails to solve it except by rote learning in a long series of trials. With a problem of such borderline difficulty, the solution may appear out of a blue sky. There is a period first of fruitless effort in one direction, or perhaps a series of attempted solutions. Then suddenly there is a complete change in the direction of effort, and a cleancut solution of the task. This then is the first criterion of the occurrence of insight. The behavior cannot be described as a gradual accretion of learning; it is evident that something has happened in the animal at the moment of solution. (What happens is another matter.) (Hebb, 1949, p. 160)

   6) An Explanation of Sudden Insight

   If the subject had not spontaneously solved the problem [of how to catch hold at the same time of two strings hung from the ceiling so wide apart that he or she could only get hold of one at a time, when the only available tool was a pair of pliers, by tying the pliers to one string and setting it into pendular motion] within ten minutes, Maier supplied him with a hint; he would "accidentally" brush against one of the strings, causing it to swing gently. Of those who solved the problem after this hint, the average interval between hint and solution was only forty-two seconds.... Most of those subjects who solved the problem immediately after the hint did so without any realization that they had been given one. The "idea" of making a pendulum with pliers seemed to arise spontaneously. (Osgood, 1960, p. 633)

   7) Flashes of Insight Do Not Explain Problem- Solving

   There seems to be very little reason to believe that solutions to novel problems come about in flashes of insight, independently of past experience.... People create solutions to new problems by starting with what they know and later modifying it to meet the specific problem at hand. (Weisberg, 1986, p. 50)

   1) To Know the Different Operations of the Mind

   It becomes, therefore, no inconsiderable part of science... to know the different operations of the mind, to separate them from each other, to class them under their proper heads, and to correct all that seeming disorder in which they lie involved when made the object of reflection and inquiry.... It cannot be doubted that the mind is endowed with several powers and faculties, that these powers are distinct from one another, and that what is really distinct to the immediate perception may be distinguished by reflection and, consequently, that there is a truth and falsehood which lie not beyond the compass of human understanding. (Hume, 1955, p. 22)

   2) The Mind Is Furnished by Experience

   Let us then suppose the mind to be, as we say, white Paper, void of all Characters, without any Ideas: How comes it to be furnished? Whence comes it by that vast store, which the busy and boundless Fancy of Man has painted on it, with an almost endless variety? Whence has it all the materials of Reason and Knowledge? To this I answer, in one word, from Experience. (Locke, quoted in Herrnstein & Boring, 1965, p. 584)

   3) Mythical Thought Is as Rigorous as That of Modern Science

   The kind of logic in mythical thought is as rigorous as that of modern science, and... the difference lies, not in the quality of the intellectual process, but in the nature of things to which it is applied.... Man has always been thinking equally well; the improvement lies, not in an alleged progress of man's mind, but in the discovery of new areas to which it may apply its unchanged and unchanging powers. (Leґvi-Strauss, 1963, p. 230)

   4) The Mind Has Nothing But Itself to Know Itself

   MIND. A mysterious form of matter secreted by the brain. Its chief activity consists in the endeavor to ascertain its own nature, the futility of the attempt being due to the fact that it has nothing but itself to know itself with. (Bierce, quoted in Minsky, 1986, p. 55)

   5) To Know Is to Represent Accurately

   [Philosophy] understands the foundations of knowledge and it finds these foundations in a study of man-as-knower, of the "mental processes" or the "activity of representation" which make knowledge possible. To know is to represent accurately what is outside the mind, so to understand the possibility and nature of knowledge is to understand the way in which the mind is able to construct such representation.... We owe the notion of a "theory of knowledge" based on an understanding of "mental processes" to the seventeenth century, and especially to Locke. We owe the notion of "the mind" as a separate entity in which "processes" occur to the same period, and especially to Descartes. We owe the notion of philosophy as a tribunal of pure reason, upholding or denying the claims of the rest of culture, to the eighteenth century and especially to Kant, but this Kantian notion presupposed general assent to Lockean notions of mental processes and Cartesian notions of mental substance. (Rorty, 1979, pp. 3-4)

   6) The Question of Mind in Relation to Machine

   Under pressure from the computer, the question of mind in relation to machine is becoming a central cultural preoccupation. It is becoming for us what sex was to Victorians-threat, obsession, taboo, and fascination. (Turkle, 1984, p. 313)

   7) Understanding the Mind Remains as Resistant to Neurological as to Cognitive Analyses

   Recent years have been exciting for researchers in the brain and cognitive sciences. Both fields have flourished, each spurred on by methodological and conceptual developments, and although understanding the mechanisms of mind is an objective shared by many workers in these areas, their theories and approaches to the problem are vastly different....

   Early experimental psychologists, such as Wundt and James, were as interested in and knowledgeable about the anatomy and physiology of the nervous system as about the young science of the mind. However, the experimental study of mental processes was short-lived, being eclipsed by the rise of behaviorism early in this century. It was not until the late 1950s that the signs of a new mentalism first appeared in scattered writings of linguists, philosophers, computer enthusiasts, and psychologists.

   In this new incarnation, the science of mind had a specific mission: to challenge and replace behaviorism. In the meantime, brain science had in many ways become allied with a behaviorist approach.... While behaviorism sought to reduce the mind to statements about bodily action, brain science seeks to explain the mind in terms of physiochemical events occurring in the nervous system. These approaches contrast with contemporary cognitive science, which tries to understand the mind as it is, without any reduction, a view sometimes described as functionalism.

   The cognitive revolution is now in place. Cognition is the subject of contemporary psychology. This was achieved with little or no talk of neurons, action potentials, and neurotransmitters. Similarly, neuroscience has risen to an esteemed position among the biological sciences without much talk of cognitive processes. Do the fields need each other?... [Y]es because the problem of understanding the mind, unlike the wouldbe problem solvers, respects no disciplinary boundaries. It remains as resistant to neurological as to cognitive analyses. (LeDoux & Hirst, 1986, pp. 1-2)

   8) Approaches to the Study of the Mind

   Since the Second World War scientists from different disciplines have turned to the study of the human mind. Computer scientists have tried to emulate its capacity for visual perception. Linguists have struggled with the puzzle of how children acquire language. Ethologists have sought the innate roots of social behaviour. Neurophysiologists have begun to relate the function of nerve cells to complex perceptual and motor processes. Neurologists and neuropsychologists have used the pattern of competence and incompetence of their brain-damaged patients to elucidate the normal workings of the brain. Anthropologists have examined the conceptual structure of cultural practices to advance hypotheses about the basic principles of the mind. These days one meets engineers who work on speech perception, biologists who investigate the mental representation of spatial relations, and physicists who want to understand consciousness. And, of course, psychologists continue to study perception, memory, thought and action.

... [W]orkers in many disciplines have converged on a number of central problems and explanatory ideas. They have realized that no single approach is likely to unravel the workings of the mind: it will not give up its secrets to psychology alone; nor is any other isolated discipline-artificial intelligence, linguistics, anthropology, neurophysiology, philosophy-going to have any greater success. (Johnson-Laird, 1988, p. 7)

   1) I Am, I Exist, Is Necessarily True

   Archimedes used to demand just one firm and immovable point in order to shift the entire earth; so I too can hope for great things if I manage to find just one thing, however slight, that is certain and unshakeable. I will suppose then, that everything is spurious. I will believe that my memory tells me lies, and that none of the things that it reports ever happened. I have no senses. Body, shape, extension, movement and place are chimeras. So what remains true? Perhaps just the fact that nothing is certain.

   Yet apart from everything I have just listed, how do I know that there is not something else which does not allow even the slightest occasion for doubt? Is there not a God, or whatever I may call him, who puts into me the thoughts I am now having? But why do I think this, since I myself may perhaps be the author of these thoughts? In that case am not I, at least, something? But I have just said that I have no senses and no body. This is the sticking point: what follows from this? Am I not so bound up with a body and with senses that I cannot exist without them? But I convinced myself that there is absolutely nothing in the world, no sky, no earth, no minds, no bodies. Does it now follow that I too do not exist?

   No: if I convinced myself of something then I certainly existed.... So after considering everything very thoroughly, I must finally conclude that this proposition, I am, I exist, is necessarily true whenever it is put forward by me or conceived in my mind. (Descartes, 1984, pp. 16-17)

   2) The Great Discoverer Does Not Seize at Once upon the Truth

   It would be an error to suppose that the great discoverer seizes at once upon the truth, or has any unerring method of divining it. In all probability the errors of the great mind exceed in number those of the less vigorous one. Fertility of imagination and abundance of guesses at truth are among the first requisites of discovery; but the erroneous guesses must be many times as numerous as those that prove well founded. The weakest analogies, the most whimsical notations, the most apparently absurd theories, may pass through the teeming brain, and no record remain of more than the hundredth part. (Jevons, 1900, p. 577)
