6 Song Yingxing (Sung Ying-Hsing)
[br]b. 1600 Chinad. c. 1650[br]Chinese writer on technology and industry.[br]Song was an outstanding encyclopedist in the field of technology and industrial processes. He produced the Tian Gong Kai Wu (The Exploitation of the Works of Nature) of 1637, China's greatest technological classic, which dealt with agriculture and industry rather than engineering. It covered a wide range of subjects, including hydraulic devices and irrigation, silk and other textiles, salt and sugar technology, ceramics, pearls and jade, papermaking and ink, metallurgy of iron, bronze, silver, tin and lead, and transport. The work incorporated the finest Chinese illustrations on these subjects. Strangely, it fell into obscurity and it was a copy preserved in Japan that became the basis for later editions.[br]Bibliography1637, Tian Gong Kai Wu.Further ReadingJ.Needham, Science and Civilisation in China, Cambridge: Cambridge University Press, 1965–86, Vols IV.2, pp. 171–2, 559; IV.3, many scattered references for it is an essential source of information about Chinese technology.LRDBiographical history of technology > Song Yingxing (Sung Ying-Hsing)

10 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, EventuallyJust 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)5) Problems in Machine Intelligence Arise Because Things Obvious to Any Person Are Not Represented in the ProgramMany 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 FormThe 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 FormationIt 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 ContextsEven 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)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 IntelligenceThe 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 PropositionsIn 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.

14 Shockley, William Bradford
[br]b. 13 February 1910 London, Englandd. 12 August 1989, Palo Alto, California, USA.[br]American physicist who developed the junction transistor from the point contact transistor and was joint winner (with John Bardeen and Walter H. Brattain) of the 1956 Nobel Prize for physics.[br]The son of a mining engineer, Shockley graduated from the California Institute of Technology in 1932 and in 1936 obtained his PhD at the Massachusetts Institute of Technology. In that year, he joined the staff of Bell Telephone Laboratories.Since the early days of radio, crystals of silicon or similar materials had been used to rectify alternating current supply until these were displaced by thermionic valves or tubes. Shockley, with Bardeen and Brattain, found that crystals of germanium containing traces of certain impurities formed far better rectifiers than crystals of the material in its pure form. The resulting device, the transistor, could also be used to amplify the current; its name is derived from its ability to transfer current across a resistor. The transistor, being so much smaller than the thermionic valve which it replaced, led to the miniaturization of electronic appliances. Another advantage was that a transistorized device needed no period of warming up, such as was necessary with a thermionic valve before it would operate. The dispersal of the heat generated by a multiplicity of thermionic valves such as were present in early computers was another problem obviated by the advent of the transistor.Shockley was responsible for much development in the field of semiconductors. He was Deputy Director of the Weapons Systems Evaluation Group of the US Department of Defense (1954–5), and in 1963 he was appointed the first Poniatoff Professor of Engineering Science at Stanford University, California. During the late 1960s Shockley became a controversial figure for expressing his unorthodox views on genetics, such as that black people were inherently less intelligent than white people, and that the population explosion spread "bad" genes at the expense of "good" genes; he supported the idea of a sperm bank from Nobel Prize winners, voluntary sterilization and the restriction of interracial marriages.[br]Principal Honours and DistinctionsNobel Prize for Physics 1956.Further ReadingI.Asimov (ed.), 1982, Biographical Encyclopedia of Science and Technology, New York: Doubleday \& Co.IMcNBiographical history of technology > Shockley, William Bradford

15 De Forest, Lee
SUBJECT AREA: Broadcasting, Electronics and information technology, Photography, film and optics, Recording, Telecommunications[br]b. 26 August 1873 Council Bluffs, Iowa, USAd. 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.[br]Principal Honours and DistinctionsInstitute of Electronic and Radio Engineers Medal of Honour 1922.

16 Townes, Charles Hard
SUBJECT AREA: Electronics and information technology[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.

18 Gabor, Dennis (Dénes)
SUBJECT AREA: Photography, film and optics[br]b. 5 June 1900 Budapest, Hungaryd. 9 February 1979 London, England[br]Hungarian (naturalized British) physicist, inventor of holography.[br]Gabor became interested in physics at an early age. Called up for military service in 1918, he was soon released when the First World War came to an end. He then began a mechanical engineering course at the Budapest Technical University, but a further order to register for military service prompted him to flee in 1920 to Germany, where he completed his studies at Berlin Technical University. He was awarded a Diploma in Engineering in 1924 and a Doctorate in Electrical Engineering in 1927. He then went on to work in the physics laboratory of Siemens \& Halske. He returned to Hungary in 1933 and developed a new kind of fluorescent lamp called the plasma lamp. Failing to find a market for this device, Gabor made the decision to abandon his homeland and emigrate to England. There he joined British Thompson-Houston (BTH) in 1934 and married a colleague from the company in 1936. Gabor was also unsuccessful in his attempts to develop the plasma lamp in England, and by 1937 he had begun to work in the field of electron optics. His work was interrupted by the outbreak of war in 1939, although as he was not yet a British subject he was barred from making any significant contribution to the British war effort. It was only when the war was near its end that he was able to return to electron optics and begin the work that led to the invention of holography. The theory was developed during 1947 and 1948; Gabor went on to demonstrate that the theories worked, although it was not until the invention of the laser in 1960 that the full potential of his invention could be appreciated. He coined the term "hologram" from the Greek holos, meaning complete, and gram, meaning written. The three-dimensional images have since found many applications in various fields, including map making, medical imaging, computing, information technology, art and advertising. Gabor left BTH to become an associate professor at the Imperial College of Science and Technology in 1949, a position he held until his retirement in 1967. In 1971 he was awarded the Nobel Prize for Physics for his work on holography.[br]Principal Honours and DistinctionsRoyal Society Rumford Medal 1968. Franklin Institute Michelson Medal 1968.

19 Kilby, Jack St Clair
SUBJECT AREA: Electronics and information technology[br]b. 8 November 1923 Jefferson City, Missouri, USA[br]American engineer who filed the first patents for micro-electronic (integrated) circuits.[br]Kilby spent most of his childhood in Great Bend, Kansas, where he often accompanied his father, an electrical power engineer, on his maintenance rounds. Working in the blizzard of 1937, his father borrowed a "ham" radio, and this fired Jack to study for his amateur licence (W9GTY) and to construct his own equipment while still a student at Great Bend High School. In 1941 he entered the University of Illinois, but four months later, after the attack on Pearl Harbor, he was enlisted in the US Army and found himself working in a radio repair workshop in India. When the war ended he returned to his studies, obtaining his BSEE from Illinois in 1947 and his MSEE from the University of Wisconsin. He then joined Centralab, a small electronics firm in Milwaukee owned by Globe-Union. There he filed twelve patents, including some for reduced titanate capacitors and for Steatite-packing of transistors, and developed a transistorized hearing-aid. During this period he also attended a course on transistors at Bell Laboratories. In May 1958, concerned to gain experience in the field of number processing, he joined Texas Instruments in Dallas. Shortly afterwards, while working alone during the factory vacation, he conceived the idea of making monolithic, or integrated, circuits by diffusing impurities into a silicon substrate to create P-N junctions. Within less than a month he had produced a complete oscillator on a chip to prove that the technology was feasible, and the following year at the 1ERE Show he demonstrated a germanium integrated-circuit flip-flop. Initially he was granted a patent for the idea, but eventually, after protracted litigation, priority was awarded to Robert Noyce of Fairchild. In 1965 he was commissioned by Patrick Haggerty, the Chief Executive of Texas Instruments, to make a pocket calculator based on integrated circuits, and on 14 April 1971 the world's first such device, the Pocketronic, was launched onto the market. Costing $150 (and weighing some 2½ lb or 1.1 kg), it was an instant success and in 1972 some 5 million calculators were sold worldwide. He left Texas Instruments in November 1970 to become an independent consultant and inventor, working on, amongst other things, methods of deriving electricity from sunlight.[br]Principal Honours and DistinctionsFranklin Institute Stuart Ballantine Medal 1966.
