  • 3 Artificial Intelligence

       In my opinion, none of [these programs] does even remote justice to the complexity of human mental processes. Unlike men, "artificially intelligent" programs tend to be single minded, undistractable, and unemotional. (Neisser, 1967, p. 9)
       Future progress in [artificial intelligence] will depend on the development of both practical and theoretical knowledge.... As regards theoretical knowledge, some have sought a unified theory of artificial intelligence. My view is that artificial intelligence is (or soon will be) an engineering discipline since its primary goal is to build things. (Nilsson, 1971, pp. vii-viii)
       Most workers in AI [artificial intelligence] research and in related fields confess to a pronounced feeling of disappointment in what has been achieved in the last 25 years. Workers entered the field around 1950, and even around 1960, with high hopes that are very far from being realized in 1972. In no part of the field have the discoveries made so far produced the major impact that was then promised.... In the meantime, claims and predictions regarding the potential results of AI research had been publicized which went even farther than the expectations of the majority of workers in the field, whose embarrassments have been added to by the lamentable failure of such inflated predictions....
       When able and respected scientists write in letters to the present author that AI, the major goal of computing science, represents "another step in the general process of evolution"; that possibilities in the 1980s include an all-purpose intelligence on a human-scale knowledge base; that awe-inspiring possibilities suggest themselves based on machine intelligence exceeding human intelligence by the year 2000 [one has the right to be skeptical]. (Lighthill, 1972, p. 17)
       4) Just as Astronomy Succeeded Astrology, the Discovery of Intellectual Processes in Machines Should Lead to a Science, Eventually
       Just as astronomy succeeded astrology, following Kepler's discovery of planetary regularities, the discoveries of these many principles in empirical explorations on intellectual processes in machines should lead to a science, eventually. (Minsky & Papert, 1973, p. 11)
       Many problems arise in experiments on machine intelligence because things obvious to any person are not represented in any program. One can pull with a string, but one cannot push with one.... Simple facts like these caused serious problems when Charniak attempted to extend Bobrow's "Student" program to more realistic applications, and they have not been faced up to until now. (Minsky & Papert, 1973, p. 77)
       What do we mean by [a symbolic] "description"? We do not mean to suggest that our descriptions must be made of strings of ordinary language words (although they might be). The simplest kind of description is a structure in which some features of a situation are represented by single ("primitive") symbols, and relations between those features are represented by other symbols-or by other features of the way the description is put together. (Minsky & Papert, 1973, p. 11)
       [AI is] the use of computer programs and programming techniques to cast light on the principles of intelligence in general and human thought in particular. (Boden, 1977, p. 5)
       The word you look for and hardly ever see in the early AI literature is the word knowledge. They didn't believe you have to know anything, you could always rework it all.... In fact 1967 is the turning point in my mind when there was enough feeling that the old ideas of general principles had to go.... I came up with an argument for what I called the primacy of expertise, and at the time I called the other guys the generalists. (Moses, quoted in McCorduck, 1979, pp. 228-229)
       9) Artificial Intelligence Is Psychology in a Particularly Pure and Abstract Form
       The basic idea of cognitive science is that intelligent beings are semantic engines-in other words, automatic formal systems with interpretations under which they consistently make sense. We can now see why this includes psychology and artificial intelligence on a more or less equal footing: people and intelligent computers (if and when there are any) turn out to be merely different manifestations of the same underlying phenomenon. Moreover, with universal hardware, any semantic engine can in principle be formally imitated by a computer if only the right program can be found. And that will guarantee semantic imitation as well, since (given the appropriate formal behavior) the semantics is "taking care of itself" anyway. Thus we also see why, from this perspective, artificial intelligence can be regarded as psychology in a particularly pure and abstract form. The same fundamental structures are under investigation, but in AI, all the relevant parameters are under direct experimental control (in the programming), without any messy physiology or ethics to get in the way. (Haugeland, 1981b, p. 31)
       There are many different kinds of reasoning one might imagine:
        Formal reasoning involves the syntactic manipulation of data structures to deduce new ones following prespecified rules of inference. Mathematical logic is the archetypical formal representation. Procedural reasoning uses simulation to answer questions and solve problems. When we use a program to answer What is the sum of 3 and 4? it uses, or "runs," a procedural model of arithmetic. Reasoning by analogy seems to be a very natural mode of thought for humans but, so far, difficult to accomplish in AI programs. The idea is that when you ask the question Can robins fly? the system might reason that "robins are like sparrows, and I know that sparrows can fly, so robins probably can fly."
        Generalization and abstraction are also natural reasoning process for humans that are difficult to pin down well enough to implement in a program. If one knows that Robins have wings, that Sparrows have wings, and that Blue jays have wings, eventually one will believe that All birds have wings. This capability may be at the core of most human learning, but it has not yet become a useful technique in AI.... Meta- level reasoning is demonstrated by the way one answers the question What is Paul Newman's telephone number? You might reason that "if I knew Paul Newman's number, I would know that I knew it, because it is a notable fact." This involves using "knowledge about what you know," in particular, about the extent of your knowledge and about the importance of certain facts. Recent research in psychology and AI indicates that meta-level reasoning may play a central role in human cognitive processing. (Barr & Feigenbaum, 1981, pp. 146-147)
       Suffice it to say that programs already exist that can do things-or, at the very least, appear to be beginning to do things-which ill-informed critics have asserted a priori to be impossible. Examples include: perceiving in a holistic as opposed to an atomistic way; using language creatively; translating sensibly from one language to another by way of a language-neutral semantic representation; planning acts in a broad and sketchy fashion, the details being decided only in execution; distinguishing between different species of emotional reaction according to the psychological context of the subject. (Boden, 1981, p. 33)
       Can the synthesis of Man and Machine ever be stable, or will the purely organic component become such a hindrance that it has to be discarded? If this eventually happens-and I have... good reasons for thinking that it must-we have nothing to regret and certainly nothing to fear. (Clarke, 1984, p. 243)
       The thesis of GOFAI... is not that the processes underlying intelligence can be described symbolically... but that they are symbolic. (Haugeland, 1985, p. 113)
        14) Artificial Intelligence Provides a Useful Approach to Psychological and Psychiatric Theory Formation
       It is all very well formulating psychological and psychiatric theories verbally but, when using natural language (even technical jargon), it is difficult to recognise when a theory is complete; oversights are all too easily made, gaps too readily left. This is a point which is generally recognised to be true and it is for precisely this reason that the behavioural sciences attempt to follow the natural sciences in using "classical" mathematics as a more rigorous descriptive language. However, it is an unfortunate fact that, with a few notable exceptions, there has been a marked lack of success in this application. It is my belief that a different approach-a different mathematics-is needed, and that AI provides just this approach. (Hand, quoted in Hand, 1985, pp. 6-7)
       We might distinguish among four kinds of AI.
       Research of this kind involves building and programming computers to perform tasks which, to paraphrase Marvin Minsky, would require intelligence if they were done by us. Researchers in nonpsychological AI make no claims whatsoever about the psychological realism of their programs or the devices they build, that is, about whether or not computers perform tasks as humans do.
       Research here is guided by the view that the computer is a useful tool in the study of mind. In particular, we can write computer programs or build devices that simulate alleged psychological processes in humans and then test our predictions about how the alleged processes work. We can weave these programs and devices together with other programs and devices that simulate different alleged mental processes and thereby test the degree to which the AI system as a whole simulates human mentality. According to weak psychological AI, working with computer models is a way of refining and testing hypotheses about processes that are allegedly realized in human minds.
    ... According to this view, our minds are computers and therefore can be duplicated by other computers. Sherry Turkle writes that the "real ambition is of mythic proportions, making a general purpose intelligence, a mind." (Turkle, 1984, p. 240) The authors of a major text announce that "the ultimate goal of AI research is to build a person or, more humbly, an animal." (Charniak & McDermott, 1985, p. 7)
       Research in this field, like strong psychological AI, takes seriously the functionalist view that mentality can be realized in many different types of physical devices. Suprapsychological AI, however, accuses strong psychological AI of being chauvinisticof being only interested in human intelligence! Suprapsychological AI claims to be interested in all the conceivable ways intelligence can be realized. (Flanagan, 1991, pp. 241-242)
        16) Determination of Relevance of Rules in Particular Contexts
       Even if the [rules] were stored in a context-free form the computer still couldn't use them. To do that the computer requires rules enabling it to draw on just those [ rules] which are relevant in each particular context. Determination of relevance will have to be based on further facts and rules, but the question will again arise as to which facts and rules are relevant for making each particular determination. One could always invoke further facts and rules to answer this question, but of course these must be only the relevant ones. And so it goes. It seems that AI workers will never be able to get started here unless they can settle the problem of relevance beforehand by cataloguing types of context and listing just those facts which are relevant in each. (Dreyfus & Dreyfus, 1986, p. 80)
       Perhaps the single most important idea to artificial intelligence is that there is no fundamental difference between form and content, that meaning can be captured in a set of symbols such as a semantic net. (G. Johnson, 1986, p. 250)
        18) The Assumption That the Mind Is a Formal System
       Artificial intelligence is based on the assumption that the mind can be described as some kind of formal system manipulating symbols that stand for things in the world. Thus it doesn't matter what the brain is made of, or what it uses for tokens in the great game of thinking. Using an equivalent set of tokens and rules, we can do thinking with a digital computer, just as we can play chess using cups, salt and pepper shakers, knives, forks, and spoons. Using the right software, one system (the mind) can be mapped into the other (the computer). (G. Johnson, 1986, p. 250)
        19) A Statement of the Primary and Secondary Purposes of Artificial Intelligence
       The primary goal of Artificial Intelligence is to make machines smarter.
       The secondary goals of Artificial Intelligence are to understand what intelligence is (the Nobel laureate purpose) and to make machines more useful (the entrepreneurial purpose). (Winston, 1987, p. 1)
       The theoretical ideas of older branches of engineering are captured in the language of mathematics. We contend that mathematical logic provides the basis for theory in AI. Although many computer scientists already count logic as fundamental to computer science in general, we put forward an even stronger form of the logic-is-important argument....
       AI deals mainly with the problem of representing and using declarative (as opposed to procedural) knowledge. Declarative knowledge is the kind that is expressed as sentences, and AI needs a language in which to state these sentences. Because the languages in which this knowledge usually is originally captured (natural languages such as English) are not suitable for computer representations, some other language with the appropriate properties must be used. It turns out, we think, that the appropriate properties include at least those that have been uppermost in the minds of logicians in their development of logical languages such as the predicate calculus. Thus, we think that any language for expressing knowledge in AI systems must be at least as expressive as the first-order predicate calculus. (Genesereth & Nilsson, 1987, p. viii)
        21) Perceptual Structures Can Be Represented as Lists of Elementary Propositions
       In artificial intelligence studies, perceptual structures are represented as assemblages of description lists, the elementary components of which are propositions asserting that certain relations hold among elements. (Chase & Simon, 1988, p. 490)
       Artificial intelligence (AI) is sometimes defined as the study of how to build and/or program computers to enable them to do the sorts of things that minds can do. Some of these things are commonly regarded as requiring intelligence: offering a medical diagnosis and/or prescription, giving legal or scientific advice, proving theorems in logic or mathematics. Others are not, because they can be done by all normal adults irrespective of educational background (and sometimes by non-human animals too), and typically involve no conscious control: seeing things in sunlight and shadows, finding a path through cluttered terrain, fitting pegs into holes, speaking one's own native tongue, and using one's common sense. Because it covers AI research dealing with both these classes of mental capacity, this definition is preferable to one describing AI as making computers do "things that would require intelligence if done by people." However, it presupposes that computers could do what minds can do, that they might really diagnose, advise, infer, and understand. One could avoid this problematic assumption (and also side-step questions about whether computers do things in the same way as we do) by defining AI instead as "the development of computers whose observable performance has features which in humans we would attribute to mental processes." This bland characterization would be acceptable to some AI workers, especially amongst those focusing on the production of technological tools for commercial purposes. But many others would favour a more controversial definition, seeing AI as the science of intelligence in general-or, more accurately, as the intellectual core of cognitive science. As such, its goal is to provide a systematic theory that can explain (and perhaps enable us to replicate) both the general categories of intentionality and the diverse psychological capacities grounded in them. (Boden, 1990b, pp. 1-2)
       Because the ability to store data somewhat corresponds to what we call memory in human beings, and because the ability to follow logical procedures somewhat corresponds to what we call reasoning in human beings, many members of the cult have concluded that what computers do somewhat corresponds to what we call thinking. It is no great difficulty to persuade the general public of that conclusion since computers process data very fast in small spaces well below the level of visibility; they do not look like other machines when they are at work. They seem to be running along as smoothly and silently as the brain does when it remembers and reasons and thinks. On the other hand, those who design and build computers know exactly how the machines are working down in the hidden depths of their semiconductors. Computers can be taken apart, scrutinized, and put back together. Their activities can be tracked, analyzed, measured, and thus clearly understood-which is far from possible with the brain. This gives rise to the tempting assumption on the part of the builders and designers that computers can tell us something about brains, indeed, that the computer can serve as a model of the mind, which then comes to be seen as some manner of information processing machine, and possibly not as good at the job as the machine. (Roszak, 1994, pp. xiv-xv)
       The inner workings of the human mind are far more intricate than the most complicated systems of modern technology. Researchers in the field of artificial intelligence have been attempting to develop programs that will enable computers to display intelligent behavior. Although this field has been an active one for more than thirty-five years and has had many notable successes, AI researchers still do not know how to create a program that matches human intelligence. No existing program can recall facts, solve problems, reason, learn, and process language with human facility. This lack of success has occurred not because computers are inferior to human brains but rather because we do not yet know in sufficient detail how intelligence is organized in the brain. (Anderson, 1995, p. 2)

  • 4 De Forest, Lee

    [br]
    b. 26 August 1873 Council Bluffs, Iowa, USA
    d. 30 June 1961 Hollywood, California, USA
    [br]
    American electrical engineer and inventor principally known for his invention of the Audion, or triode, vacuum tube; also a pioneer of sound in the cinema.
    [br]
    De Forest was born into the family of a Congregational minister that moved to Alabama in 1879 when the father became President of a college for African-Americans; this was a position that led to the family's social ostracism by the white community. By the time he was 13 years old, De Forest was already a keen mechanical inventor, and in 1893, rejecting his father's plan for him to become a clergyman, he entered the Sheffield Scientific School of Yale University. Following his first degree, he went on to study the propagation of electromagnetic waves, gaining a PhD in physics in 1899 for his thesis on the "Reflection of Hertzian Waves from the Ends of Parallel Wires", probably the first US thesis in the field of radio.
    He then joined the Western Electric Company in Chicago where he helped develop the infant technology of wireless, working his way up from a modest post in the production area to a position in the experimental laboratory. There, working alone after normal working hours, he developed a detector of electromagnetic waves based on an electrolytic device similar to that already invented by Fleming in England. Recognizing his talents, a number of financial backers enabled him to set up his own business in 1902 under the name of De Forest Wireless Telegraphy Company; he was soon demonstrating wireless telegraphy to interested parties and entering into competition with the American Marconi Company.
    Despite the failure of this company because of fraud by his partners, he continued his experiments; in 1907, by adding a third electrode, a wire mesh, between the anode and cathode of the thermionic diode invented by Fleming in 1904, he was able to produce the amplifying device now known as the triode valve and achieve a sensitivity of radio-signal reception much greater than possible with the passive carborundum and electrolytic detectors hitherto available. Patented under the name Audion, this new vacuum device was soon successfully used for experimental broadcasts of music and speech in New York and Paris. The invention of the Audion has been described as the beginning of the electronic era. Although much development work was required before its full potential was realized, the Audion opened the way to progress in all areas of sound transmission, recording and reproduction. The patent was challenged by Fleming and it was not until 1943 that De Forest's claim was finally recognized.
    Overcoming the near failure of his new company, the De Forest Radio Telephone Company, as well as unsuccessful charges of fraudulent promotion of the Audion, he continued to exploit the potential of his invention. By 1912 he had used transformer-coupling of several Audion stages to achieve high gain at radio frequencies, making long-distance communication a practical proposition, and had applied positive feedback from the Audion output anode to its input grid to realize a stable transmitter oscillator and modulator. These successes led to prolonged patent litigation with Edwin Armstrong and others, and he eventually sold the manufacturing rights, in retrospect often for a pittance.
    During the early 1920s De Forest began a fruitful association with T.W.Case, who for around ten years had been working to perfect a moving-picture sound system. De Forest claimed to have had an interest in sound films as early as 1900, and Case now began to supply him with photoelectric cells and primitive sound cameras. He eventually devised a variable-density sound-on-film system utilizing a glow-discharge modulator, the Photion. By 1926 De Forest's Phonofilm had been successfully demonstrated in over fifty theatres and this system became the basis of Movietone. Though his ideas were on the right lines, the technology was insufficiently developed and it was left to others to produce a system acceptable to the film industry. However, De Forest had played a key role in transforming the nature of the film industry; within a space of five years the production of silent films had all but ceased.
    In the following decade De Forest applied the Audion to the development of medical diathermy. Finally, after spending most of his working life as an independent inventor and entrepreneur, he worked for a time during the Second World War at the Bell Telephone Laboratories on military applications of electronics.

  • 5 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)
       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)
       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)
       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)
       [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)
       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)
       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)

    SUBJECT AREA: Telecommunications
    [br]
    fl. 1850s
    [br]
    British inventor of the "copying telegraph", the basis of facsimile transmission.
    [br]
    Although little appears to be known about his life, Bakewell deserves a place in this dictionary for a single invention that was to have a significant impact upon communication. The invention of photography early in the nineteenth century soon led to a desire to transmit images over a distance. Although telegraphy was still very much in its infancy, Bakewell realized that the key to a viable system of facsimile, as it came to be known, was to dissect the image to be transmitted sequentially by scanning it in a series of parallel lines with some sort of sensor and to synchronously reconstruct it at the receiving end—a process that anticipated the way in which modern television works. To this end the line image was drawn with varnish on a sheet of tin foil, which was then wrapped around a cylinder. As the cylinder was rotated, presumably by some kind of regulated clockwork mechanism similar to that used later in the early phonographs of Edison, an electrical contact driven by a screw thread caused the image to be scanned along a spiral path, giving a series of on-off signals. At the receiving end, instead of the tin foil, a sheet of paper wetted with a suitable chemical was darkened by the current pulses as they arrived.
    A practicable system did not become possible until a dry form of receiving-paper that was insensitive to light became available in the 1930s; once established, however, the technique remained the basis of commercial machines into the 1980s.

  • 7 Carnot, Nicolas Léonard Sadi

    [br]
    b. 1 June 1796 Paris, France
    d. 24 August 1831 Paris, France
    [br]
    French laid the foundations for modern thermodynamics through his book Réflexions sur la puissance motrice du feu when he stated that the efficiency of an engine depended on the working substance and the temperature drop between the incoming and outgoing steam.
    [br]
    Sadi was the eldest son of Lazare Carnot, who was prominent as one of Napoleon's military and civil advisers. Sadi was born in the Palais du Petit Luxembourg and grew up during the Napoleonic wars. He was tutored by his father until in 1812, at the minimum age of 16, he entered the Ecole Polytechnique to study stress analysis, mechanics, descriptive geometry and chemistry. He organized the students to fight against the allies at Vincennes in 1814. He left the Polytechnique that October and went to the Ecole du Génie at Metz as a student second lieutenant. While there, he wrote several scientific papers, but on the Restoration in 1815 he was regarded with suspicion because of the support his father had given Napoleon. In 1816, on completion of his studies, Sadi became a second lieutenant in the Metz engineering regiment and spent his time in garrison duty, drawing up plans of fortifications. He seized the chance to escape from this dull routine in 1819 through an appointment to the army general staff corps in Paris, where he took leave of absence on half pay and began further courses of study at the Sorbonne, Collège de France, Ecole des Mines and the Conservatoire des Arts et Métiers. He was inter-ested in industrial development, political economy, tax reform and the fine arts.
    It was not until 1821 that he began to concentrate on the steam-engine, and he soon proposed his early form of the Carnot cycle. He sought to find a general solution to cover all types of steam-engine, and reduced their operation to three basic stages: an isothermal expansion as the steam entered the cylinder; an adiabatic expansion; and an isothermal compression in the condenser. In 1824 he published his Réflexions sur la puissance motrice du feu, which was well received at the time but quickly forgotten. In it he accepted the caloric theory of heat but pointed out the impossibility of perpetual motion. His main contribution to a correct understanding of a heat engine, however, lay in his suggestion that power can be produced only where there exists a temperature difference due "not to an actual consumption of caloric but to its transportation from a warm body to a cold body". He used the analogy of a water-wheel with the water falling around its circumference. He proposed the true Carnot cycle with the addition of a final adiabatic compression in which motive power was con sumed to heat the gas to its original incoming temperature and so closed the cycle. He realized the importance of beginning with the temperature of the fire and not the steam in the boiler. These ideas were not taken up in the study of thermodynartiics until after Sadi's death when B.P.E.Clapeyron discovered his book in 1834.
    In 1824 Sadi was recalled to military service as a staff captain, but he resigned in 1828 to devote his time to physics and economics. He continued his work on steam-engines and began to develop a kinetic theory of heat. In 1831 he was investigating the physical properties of gases and vapours, especially the relationship between temperature and pressure. In June 1832 he contracted scarlet fever, which was followed by "brain fever". He made a partial recovery, but that August he fell victim to a cholera epidemic to which he quickly succumbed.

  • 8 Parsons, Sir Charles Algernon

    [br]
    b. 13 June 1854 London, England
    d. 11 February 1931 on board Duchess of Richmond, Kingston, Jamaica
    [br]
    English eingineer, inventor of the steam turbine and developer of the high-speed electric generator.
    [br]
    The youngest son of the Earl of Rosse, he came from a family well known in scientific circles, the six boys growing up in an intellectual atmosphere at Birr Castle, the ancestral home in Ireland, where a forge and large workshop were available to them. Charles, like his brothers, did not go to school but was educated by private tutors of the character of Sir Robert Ball, this type of education being interspersed with overseas holiday trips to France, Holland, Belgium and Spain in the family yacht. In 1871, at the age of 17, he went to Trinity College, Dublin, and after two years he went on to St John's College, Cambridge. This was before the Engineering School had opened, and Parsons studied mechanics and mathematics.
    In 1877 he was apprenticed to W.G.Armstrong \& Co. of Elswick, where he stayed for four years, developing an epicycloidal engine that he had designed while at Cambridge. He then moved to Kitson \& Co. of Leeds, where he went half shares in a small experimental shop working on rocket propulsion for torpedoes.
    In 1887 he married Katherine Bethell, who contracted rheumatic fever from early-morning outdoor vigils with her husband to watch his torpedo experiments while on their honeymoon! He then moved to a partnership in Clarke, Chapman \& Co. at Gateshead. There he joined the electrical department, initially working on the development of a small, steam-driven marine lighting set. This involved the development of either a low-speed dynamo, for direct coupling to a reciprocating engine, or a high-speed engine, and it was this requirement that started Parsons on the track of the steam turbine. This entailed many problems such as the running of shafts at speeds of up to 40,000 rpm and the design of a DC generator for 18,000 rpm. He took out patents for both the turbine and the generator on 23 April 1884. In 1888 he dissolved his partnership with Clarke, Chapman \& Co. to set up his own firm in Newcastle, leaving his patents with the company's owners. This denied him the use of the axial-flow turbine, so Parsons then designed a radial-flow layout; he later bought back his patents from Clarke, Chapman \& Co. His original patent had included the use of the steam turbine as a means of marine propulsion, and Parsons now set about realizing this possibility. He experimented with 2 ft (61 cm) and 6 ft (183 cm) long models, towed with a fishing line or, later, driven by a twisted rubber cord, through a single-reduction set of spiral gearing.
    The first trials of the Turbinia took place in 1894 but were disappointing due to cavitation, a little-understood phenomenon at the time. He used an axial-flow turbine of 2,000 shp running at 2,000 rpm. His work resulted in a far greater understanding of the phenomenon of cavitation than had hitherto existed. Land turbines of up to 350 kW (470 hp) had meanwhile been built. Experiments with the Turbinia culminated in a demonstration which took place at the great Naval Review of 1897 at Spithead, held to celebrate Queen Victoria's Diamond Jubilee. Here, the little Turbinia darted in and out of the lines of heavy warships and destroyers, attaining the unheard of speed of 34.5 knots. The following year the Admiralty placed their first order for a turbine-driven ship, and passenger vessels started operation soon after, the first in 1901. By 1906 the Admiralty had moved over to use turbines exclusively. These early turbines had almost all been direct-coupled to the ship's propeller shaft. For optimum performance of both turbine and propeller, Parsons realized that some form of reduction gearing was necessary, which would have to be extremely accurate because of the speeds involved. Parsons's Creep Mechanism of 1912 ensured that any errors in the master wheel would be distributed evenly around the wheel being cut.
    Parsons was also involved in optical work and had a controlling interest in the firm of Ross Ltd of London and, later, in Sir Howard Grubb \& Sons. He he was an enlightened employer, originating share schemes and other benefits for his employees.

    SUBJECT AREA: Ports and shipping
    [br]
    fl. 752/820 China
    [br]
    Chinese physicist, technologist and patron of engineers.
    [br]
    Li Gao was Prince of Cao (Tshao). He was interested in acoustics and carried out experiments on both hydrostatic and air pressure. He constructed "trick" hydrostatic vessels that could take up different positions according to the amount of water in them. Such vessels had been known since the third century BC and were popular at court for over a thousand years: Li's were made of lacquered wood, c. 790, probably in quantity. He made successful use of paddle warships operated by treadmills. Similar vessels may have been in use as early as the late fifth century, but this is not at all certain. Li Gao's ships are therefore the first practical achievement of an idea for ship propulsion that, probably independently, had been mooted but not realized in early Byzantine times in Europe. His experiments with this type of vessel were made during 782 to 785, while he was Governor of Hungchow. It was said that the ships "went like the wind", faster than a charging horse.

    [br]
    b. 1550 Merchiston Castle, Edinburgh, Scotland
    d. 4 April 1617 Merchiston Castle, Edinburgh, Scotland
    [br]
    Scottish mathematician and theological writer noted for his discovery of logarithms, a powerful aid to mathematical calculations.
    [br]
    Born into a family of Scottish landowners, at the early age of 13 years Napier went to the University of St Andrews in Fife, but he apparently left before taking his degree. An extreme Protestant, he was active in the struggles with the Roman Catholic Church and in 1594 he dedicated to James VI of Scotland his Plaine Discovery of the Whole Revelation of St John, an attempt to promote the Protestant case in the guise of a learned study. About this time, as well as being involved in the development of military equipment, he devoted much of his time to finding methods of simplifying the tedious calculations involved in astronomy. Eventually he realized that by representing numbers in terms of the power to which a "base" number needed to be raised to produce them, it was possible to perform multiplication and division and to find roots, by the simpler processes of addition, substraction and integer division, respectively.
    A description of the principle of his "logarithms" (from the Gk. logos, reckoning, and arithmos, number), how he arrived at the idea and how they could be used was published in 1614 under the title Mirifici Logarithmorum Canonis Descriptio. Two years after his death his Mirifici Logarithmorum Canonis Constructio appeared, in which he explained how to calculate the logarithms of numbers and gave tables of them to eight significant figures, a novel feature being the use of the decimal point to distinguish the integral and fractional parts of the logarithm. As originally conceived, Napier's tables of logarithms were calculated using the natural number e(=2.71828…) as the base, not directly, but in effect according to the formula: Naperian logx= 107(log e 107-log e x) so that the original Naperian logarithm of a number decreased as the number increased. However, prior to his death he had readily acceded to a suggestion by Henry Briggs that it would greatly facilitate their use if logarithms were simply defined as the value to which the decimal base 10 needed to be raised to realize the number in question. He was almost certainly also aware of the work of Joost Burgi.
    No doubt as an extension of his ideas of logarithms, Napier also devised a means of manually performing multiplication and division by means of a system of rods known as Napier's Bones, a forerunner of the modern slide-rule, which evolved as a result of successive developments by Edmund Gunther, William Oughtred and others. Other contributions to mathematics by Napier include important simplifying discoveries in spherical trigonometry. However, his discovery of logarithms was undoubtedly his greatest achievement.

    Napier's "Descriptio" and his "Constructio" were published in English translation as Description of the Marvelous Canon of Logarithms (1857) and W.R.MacDonald's Construction of the Marvelous Canon of Logarithms (1889), which also catalogues all his works. His Rabdologiae, seu Numerationis per Virgulas Libri Duo (1617) was published in English as Divining Rods, or Two Books of Numbering by Means of Rods (1667).

    [br]
    b. 1797 Madeley, Staffordshire, England
    d. 23 July 1872 Broadstairs, Kent, England
    [br]
    English inventory particularly of road and rail vehicles and their equipment.
    [br]
    Ill health forced Adams to live abroad when he was a young man and when he returned to England in the early 1830s he became a partner in his father's firm of coachbuilders. Coaches during that period were steered by a centrally pivoted front axle, which meant that the front wheels had to swing beneath the body and were therefore made smaller than the rear wheels. Adams considered this design defective and invented equirotal coaches, built by his firm, in which the front and rear wheels were of equal diameter and the coach body was articulated midway along its length so that the front part pivoted. He also applied himself to improving vehicles for railways, which were developing rapidly then.
    In 1843 he opened his own engineering works, Fairfield Works in north London (he was not related to his contemporary William Adams, who was appointed Locomotive Superintendent to the North London Railway in 1854). In 1847 he and James Samuel, Engineer to the Eastern Counties Railway, built for that line a small steam inspection car, the Express, which was light enough to be lifted off the track. The following year Adams built a broad-gauge steam railcar, the Fairfield, for the Bristol \& Exeter Railway at the insistance of the line's Engineer, C.H.Gregory: self-propelled and passenger-carrying, this was the first railcar. Adams developed the concept further into a light locomotive that could haul two or three separate carriages, and light locomotives built both by his own firm and by other noted builders came into vogue for a decade or more.
    In 1847 Adams also built eight-wheeled coaches for the Eastern Counties Railway that were larger and more spacious than most others of the day: each in effect comprised two four-wheeled coaches articulated together, with wheels that were allowed limited side-play. He also realized the necessity for improvements to railway track, the weakest point of which was the joints between the rails, whose adjoining ends were normally held in common chairs. Adams invented the fishplated joint, first used by the Eastern Counties Railway in 1849 and subsequently used almost universally.
    Adams was a prolific inventor. Most important of his later inventions was the radial axle, which was first applied to the leading and trailing wheels of a 2–4–2 tank engine, the White Raven, built in 1863; Adams's radial axle was the forerunner of all later radial axles. However, the sprung tyres with which White Raven was also fitted (an elastic steel hoop was interposed between wheel centre and tyre) were not perpetuated. His inventiveness was not restricted to engineering: in matters of dress, his adoption, perhaps invention, of the turn-down collar at a time when men conventionally wore standup collars had lasting effect.
    [br]
    Bibliography
    Adams took out some thirty five British patents, including one for the fishplate in 1847. He wrote copiously, as journalist and author: his most important book was English Pleasure Carriages (1837), a detailed description of coachbuilding, together with ideas for railway vehicles and track. The 1971 reprint (Bath: Adams \& Dart) has a biographical introduction by Jack Simmons.

  • 14 Lovelock, James Ephraim

    [br]
    b. 26 July 1919 Brixton, London, England
    [br]
    English biologist and philosopher, inventor of the microwave oven and electron capture detector.
    [br]
    Lovelock was brought up in Brixton in modest circumstances. At the age of 4 he was given a toy electrical set, which first turned his attention towards the study of science. From the Strand School, Brixton, he went on to the universities of Manchester and London, and after graduating in science, in 1941 he joined the National Institute for Medical Research, Mill Hill, as a staff scientist, remaining there for twenty years. During the early 1950s, he and his colleagues were engaged in research into freezing live animals and bringing them back to life by heating: Lovelock was struck by the intense pain this process caused the animals, and he sought a more humane method. He tried diathermy or internal heating through the effect of a continuous wave magnetron borrowed from the Navy. He found that the animals were brought back to life painlessly, and impressed with his success he tried baking a potato for his lunch in the apparatus and found that it cooked amazingly quickly compared with the one hour normally needed in an ordinary oven. Lovelock had invented the microwave oven, but its commercial possibilities were not at first realized.
    In the late 1950s he invented the electron capture detector, which proved to be more sensitive than any other analytical equipment in detecting and measuring toxic substances. The apparatus therefore had obvious uses in testing the quality of the environment and so offered a tremendous boost to the "green" movement. In 1961 he was invited to joint the US National Aeronautics and Space Administration (NASA) to employ the apparatus in an attempt to detect life in space.
    In the early 1970s Lovelock relinquished his biological work in order to devote his attention to philosophical matters, specifically to develop his theory of the Universe, now widely celebrated as the "Gaia theory". In this controversial theory, Lovelock regards our planet and all its living beings, including humans, as a single living organism.

  • 15 Torricelli, Evangelista

    [br]
    b. 15 October 1608 Faenza, Italy
    d. 25 October 1647 Florence, Italy
    [br]
    Italian physicist, inventor of the mercury barometer and discoverer of atmospheric pressure.
    [br]
    Torricelli was the eldest child of a textile artisan. Between 1625 and 1626 he attended the Jesuit school at Faenza, where he showed such outstanding aptitude in mathematics and philosophy that his uncle was persuaded to send him to Rome to a school run by Benedetto Castelli, a mathematician and engineer and a former pupil of Galileo Galilei. Between 1630 and 1641, Torricelli was possibly Secretary to Giovanni Ciampoli, Galileo's friend and protector. In 1641 Torricelli wrote a treatise, De motugravium, amplifying Galileo's doctrine on the motion of projectiles, and Galileo accepted him as a pupil. On Galileo's death in 1642, he was appointed as mathematician and philosopher to the court of Grand Duke Ferdinando II of Tuscany. He remained in Florence until his early death in 1647, possibly from typhoid fever. He wrote a great number of mathematical papers on conic sections, the cycloid, the logarithmic curve and other subjects, which made him well known.
    By 1642 Torricelli was producing good lenses for telescopes; he subsequently improved them, and attained near optical perfection. He also constructed a simple microscope with a small glass sphere as a lens. Galileo had looked at problems of raising water with suction pumps, and also with a siphon in 1630. Torricelli brought up the subject again in 1640 and later produced his most important invention, the barometer. He used mercury to fill a glass tube that was sealed at one end and inverted it. He found that the height of mercury in the tube adjusted itself to a well-defined level of about 76 cm (30 in.), higher than the free surface outside. He realized that this must be due to the pressure of the air on the outside surface and predicted that it would fall with increasing altitude. He thus demonstrated the pressure of the atmosphere and the existence of a vacuum on top of the mercury, publishing his findings in 1644. He later noticed that changes in the height of the mercury were related to changes in the weather.

  • 16 Trevithick, Richard

    [br]
    b. 13 April 1771 Illogan, Cornwall, England
    d. 22 April 1833 Dartford, Kent, England
    [br]
    English engineer, pioneer of non-condensing steam-engines; designed and built the first locomotives.
    [br]
    Trevithick's father was a tin-mine manager, and Trevithick himself, after limited formal education, developed his immense engineering talent among local mining machinery and steam-engines and found employment as a mining engineer. Tall, strong and high-spirited, he was the eternal optimist.
    About 1797 it occurred to him that the separate condenser patent of James Watt could be avoided by employing "strong steam", that is steam at pressures substantially greater than atmospheric, to drive steam-engines: after use, steam could be exhausted to the atmosphere and the condenser eliminated. His first winding engine on this principle came into use in 1799, and subsequently such engines were widely used. To produce high-pressure steam, a stronger boiler was needed than the boilers then in use, in which the pressure vessel was mounted upon masonry above the fire: Trevithick designed the cylindrical boiler, with furnace tube within, from which the Cornish and later the Lancashire boilers evolved.
    Simultaneously he realized that high-pressure steam enabled a compact steam-engine/boiler unit to be built: typically, the Trevithick engine comprised a cylindrical boiler with return firetube, and a cylinder recessed into the boiler. No beam intervened between connecting rod and crank. A master patent was taken out.
    Such an engine was well suited to driving vehicles. Trevithick built his first steam-carriage in 1801, but after a few days' use it overturned on a rough Cornish road and was damaged beyond repair by fire. Nevertheless, it had been the first self-propelled vehicle successfully to carry passengers. His second steam-carriage was driven about the streets of London in 1803, even more successfully; however, it aroused no commercial interest. Meanwhile the Coalbrookdale Company had started to build a locomotive incorporating a Trevithick engine for its tramroads, though little is known of the outcome; however, Samuel Homfray's ironworks at Penydarren, South Wales, was already building engines to Trevithick's design, and in 1804 Trevithick built one there as a locomotive for the Penydarren Tramroad. In this, and in the London steam-carriage, exhaust steam was turned up the chimney to draw the fire. On 21 February the locomotive hauled five wagons with 10 tons of iron and seventy men for 9 miles (14 km): it was the first successful railway locomotive.
    Again, there was no commercial interest, although Trevithick now had nearly fifty stationary engines completed or being built to his design under licence. He experimented with one to power a barge on the Severn and used one to power a dredger on the Thames. He became Engineer to a project to drive a tunnel beneath the Thames at Rotherhithe and was only narrowly defeated, by quicksands. Trevithick then set up, in 1808, a circular tramroad track in London and upon it demonstrated to the admission-fee-paying public the locomotive Catch me who can, built to his design by John Hazledine and J.U. Rastrick.
    In 1809, by which date Trevithick had sold all his interest in the steam-engine patent, he and Robert Dickinson, in partnership, obtained a patent for iron tanks to hold liquid cargo in ships, replacing the wooden casks then used, and started to manufacture them. In 1810, however, he was taken seriously ill with typhus for six months and had to return to Cornwall, and early in 1811 the partners were bankrupt; Trevithick was discharged from bankruptcy only in 1814.
    In the meantime he continued as a steam engineer and produced a single-acting steam engine in which the cut-off could be varied to work the engine expansively by way of a three-way cock actuated by a cam. Then, in 1813, Trevithick was approached by a representative of a company set up to drain the rich but flooded silver-mines at Cerro de Pasco, Peru, at an altitude of 14,000 ft (4,300 m). Low-pressure steam engines, dependent largely upon atmospheric pressure, would not work at such an altitude, but Trevithick's high-pressure engines would. Nine engines and much other mining plant were built by Hazledine and Rastrick and despatched to Peru in 1814, and Trevithick himself followed two years later. However, the war of independence was taking place in Peru, then a Spanish colony, and no sooner had Trevithick, after immense difficulties, put everything in order at the mines then rebels arrived and broke up the machinery, for they saw the mines as a source of supply for the Spanish forces. It was only after innumerable further adventures, during which he encountered and was assisted financially by Robert Stephenson, that Trevithick eventually arrived home in Cornwall in 1827, penniless.
    He petitioned Parliament for a grant in recognition of his improvements to steam-engines and boilers, without success. He was as inventive as ever though: he proposed a hydraulic power transmission system; he was consulted over steam engines for land drainage in Holland; and he suggested a 1,000 ft (305 m) high tower of gilded cast iron to commemorate the Reform Act of 1832. While working on steam propulsion of ships in 1833, he caught pneumonia, from which he died.

  • 17 Clarke, Arthur Charles

    [br]
    b. 16 December 1917 Minehead, Somerset, England
    [br]
    English writer of science fiction who correctly predicted the use of geo-stationary earth satellites for worldwide communications.
    [br]
    Whilst still at Huish's Grammar School, Taunton, Clarke became interested in both space science and science fiction. Unable to afford a scientific education at the time (he later obtained a BSc at King's College, London), he pursued both interests in his spare time while working in the Government Exchequer and Audit Department between 1936 and 1941. He was a founder member of the British Interplanetary Society, subsequently serving as its Chairman in 1946–7 and 1950–3. From 1941 to 1945 he served in the Royal Air Force, becoming a technical officer in the first GCA (Ground Controlled Approach) radar unit. There he began to produce the first of many science-fiction stories. In 1949–50 he was an assistant editor of Science Abstracts at the Institution of Electrical Engineers.
    As a result of his two interests, he realized during the Second World War that an artificial earth satellite in an equatorial orbital with a radius of 35,000 km (22,000 miles) would appear to be stationary, and that three such geo-stationary, or synchronous, satellites could be used for worldwide broadcast or communications. He described these ideas in a paper published in Wireless World in 1945. Initially there was little response, but within a few years the idea was taken up by the US National Aeronautics and Space Administration and in 1965 the first synchronous satellite, Early Bird, was launched into orbit.
    In the 1950s he moved to Ceylon (now Sri Lanka) to pursue an interest in underwater exploration, but he continued to write science fiction, being known in particular for his contribution to the making of the classic Stanley Kubrick science-fiction film 2001: A Space Odyssey, based on his book of the same title.
    [br]
    Principal Honours and Distinctions
    Clarke received many honours for both his scientific and science-fiction writings. For his satellite communication ideas his awards include the Franklin Institute Gold Medal 1963 and Honorary Fellowship of the American Institute of Aeronautics and Astronautics 1976. For his science-fiction writing he received the UNESCO Kalinga Prize (1961) and many others. In 1979 he became Chancellor of Moratuwa University in Sri Lanka and in 1980 Vikran Scrabhai Professor at the Physical Research Laboratory of the University of Ahmedabad.

  • 19 Allen, John F.

    [br]
    b. 1829 England
    d. 2 October 1900 New York (?), USA
    [br]
    English inventor of the Allen valve used on his pioneering high-speed engines.
    [br]
    Allen was taken to the United States from England when he was 12 years old. He became an engineer on the Curlew, a freight boat running between New York and Providence. A defect which caused the engine to race in rough weather led Allen to invent a new valve gear, but he found it could not be fitted to the Corliss engine. In 1856 he patented an improved form of valve and operating gear to reduce back-pressure in the cylinder, which was in fact the reverse of what happened in his later engines. In 1860 he repaired the engines of a New York felt-hat manufacturer, Henry Burr, and that winter he was introduced to Charles Porter. Porter realized the potential of Allen's valves for his idea of a high-speed engine, and the Porter-Allen engine became the pioneer of high-speed designs.
    Porter persuaded Allen to patent his new valves and two patents were obtained in 1862. These valves could be driven positively and yet the travel of the inlet could be varied to give the maximum expansion at different cut-offs. Also, the valves allowed an exceptionally good flow of steam. While Porter went to England and tried to interest manufacturers there, Allen remained in America and continued work on the engine. Within a few years he invented an inclined watertube boiler, but he seemed incapable of furthering his inventions once they had been placed on the market. Although he mortgaged his own house in order to help finance the factory for building the steam engine, in the early 1870s he left Porter and built a workshop of his own at Mott Haven. There he invented important systems for riveting by pneumatic machines through both percussion and pressure which led into the production of air compressors and riveting machines.

    [br]
    b. 28 July 1915 Greenville, South Carolina, USA
    [br]
    American physicist who developed the maser and contributed to the development of the laser.
    [br]
    Charles H.Townes entered Furman University, Greenville, at the early age of 16 and in 1935 obtained a BA in modern languages and a BS in physics. After a year of postgraduate study at Duke University, he received a master's degree in physics in 1936. He then went on to the California Institute of Technology, where he obtained a PhD in 1939. From 1939 to 1947 he worked at the Bell Telephone Laboratories, mainly on airborne radar, although he also did some work on radio astronomy. In 1948 he joined Columbia University as Associate Professor of Physics and in 1950 was appointed a full professor. He was Director of the University's Radiation Laboratory from 1950 to 1952, and from 1952 to 1955 he was Chairman of the Physics Department.
    To meet the need for an oscillator generating very short wavelength electromagnetic radiation, Townes in 1951 realized that use could be made of the different natural energy levels of atoms and molecules. The practical application of this idea was achieved in his laboratory in 1953 using ammonia gas to make the device known as a maser (an acronym of microwave amplification by stimulated emission of radiation). The maser was developed in the next few years and in 1958, in a joint paper with his brother-in-law Arthur L. Schawlow, Townes suggested the possibility of a further development into optical frequencies or an optical maser, later known as a laser (an acronym of light amplification by stimulated emission of radiation). Two years later the first such device was made by Theodore H. Maiman.
    In 1959 Townes was given leave from Columbia University to serve as Vice-President and Director of Research at the Institute for Defense Analyses until 1961. He was then appointed Provost and Professor of Physics at the Massachusetts Institute of Technology. In 1967 he became University Professor of Physics at the University of California, where he has extended his research interests in the field of microwave and infra-red astronomy. He is a member of the National Academy of Sciences, the Institute of Electrical and Electronics Engineers and the American Astronomical Society.
