Computer Science

"Cyborg. The word has a whiff of the implausible about it that leads many people to discount it as mere fantasy. Yet cyborgs, real ones, have been among us for almost 50 years. The world's first cyborg was a white lab rat, part of an experimental program at New York's Rockland State Hospital in the late 1950s. The rat had implanted in its body a tiny osmotic pump that injected precisely controlled doses of chemicals, altering various of its physiological parameters. It was part animal, part machine."

"In the late 1950s, experiments such as the cybernetic sculptures of Nicolas Schöffer or the programmatic music compositions of John Cage and Iannis Xenakis transposed systems theory from the sciences to the arts. By the 1960s, artists as diverse as , Hans Haacke, Robert Morris, Sonia Sheridan, and were breaking with accepted aesthetics to embrace open systems that emphasized organism over mechanism, dynamic processes of interaction among elements, and the observer’s role as an inextricable part of the system. Jack Burnham’s 1968 Artforum essay “Systems Aesthetics” and his 1970 “Software” exhibition marked the high point of systems-based art until its resurgence in the changed conditions of the twenty-first century."

"For me, as I later came to say, cybernetics is the art of creating equilibrium in a world of possibilities and constraints. This is not just a romantic description, it portrays the new way of thinking quite accurately. Cybernetics differs from the traditional scientific procedure, because it does not try to explain phenomena by searching for their causes, but rather by specifying the constraints that determine the direction of their development."

"Since the 1960s, Japan has produced a considerable number of cyborg narratives in manga and anime, particularly in works targeting male children and adolescents. From early manga examples such as Kazumasa Hirai and Hiro Kuwata's 8 Man and Shotaro Ishinomori's Cyborg 009, and their subsequent anime versions, the protagonist is commonly cyborged against their will or desires. This positions them as victims, regardless of how physically powerful they are. Their sense of inferiority and vulnerability usually underpins these narratives, either subtly or explicitly. The depiction of female cyborgs adds complexity to the positioning of cyborgs in manga and anime, especially in terms of gender. Female cyborgs may be equipped with remarkable physical strength, combined with voluptuous, eroticized bodies (for instance Major Motoko Kusanagi in Masamune Shirow's original manga and Mamoru Oshii's anime version of Ghost in the Shell); and these powerful female cyborgs are also frequently ascribed roles as protectors or supporters of incompetent and insecure male protagonists. Although some female cyborgs may possess characteristics that indicate a transgression of the conventional boundaries of gender, this transgression is often limited and undermined by other elements of their depiction. As Kumiko Sato points out in her essay "How Information Technology Has "Not, Changed Feminism and Japanism", "female cyborgs and androids have been domesticated and fetishized into maternal and sexual protectors of the male hero" and thus "their functions is usually reduced to either a maid or a goddess obediantly serving her beloved male master, the sole reason for her militant nature.""

"Cybernetics is the study of systems and processes that interact with themselves and produce themselves from themselves."

"Many of the core ideas of cybernetics have been assimilated by other disciplines, where they continue to influence scientific developments. Other important cybernetic principles seem to have been forgotten, though, only to be periodically rediscovered or reinvented in different domains. Some examples are the rebirth of neural networks, first invented by cyberneticists in the 1940's, in the late 1960's and again in the late 1980's; the rediscovery of the importance of autonomous interaction by robotics and AI in the 1990's; and the significance of positive feedback effects in complex systems, rediscovered by economists in the 1990's. Perhaps the most significant recent development is the growth of the complex adaptive systems movement, which, in the work of authors such as John Holland, Stuart Kauffman and Brian Arthur and the subfield of , has used the power of modern computers to simulate and thus experiment with and develop many of the ideas of cybernetics. It thus seems to have taken over the cybernetics banner in its mathematical modelling of complex systems across disciplinary boundaries, however, while largely ignoring the issues of goal-directedness and control."

"An opportunity for cybernetics to change the course of the philosophy of mind was missed when intentionality was misinterpreted as "the providing of coded knowledge"."

"Wiener's dream of a universal science of communication and control has faded with the years. Cybernetics has given rise to new areas like cognitive science and stimulated valuable research in numerous other fields. But almost no one today calls themselves a cyberneticist. Some believe that Wiener's project fell victim to scientific fashion, its funding sucked away by flashy but ultimately pointless AI research. Others think cybernetics was killed by the basic problem that the nuts-and-bolts mechanisms of control and communication in machines are significantly different from those in animals, and neither are very like control and communication in society. So cybernetics, which was based on an inspired generalization, fell victim to its inability to deal with details. Whichever perspective is true (and as with most such stories, the truth is likely to be a mixture of both), cybernetics has left two important cultural residues behind. The first is its picture of the world as a collection of networks. The second is its intuition that there's not as much clear blue water between people and machines as some would like to believe. These still-controversial concepts are at the bionic heart of the cyborg, which is alive and well, and constructing itself in a laboratory near you."

"From the start, the cyborg was more than just another technical project; it was a kind of scientific and military daydream. The possibility of escaping its annoying bodily limitations led a generation that grew up on Superman and Captain America to throw the full weight of its grown-up R&D budget into achieving a real-life superpower. By the mid-1960s, cyborgs were big business, with millions of US Air Force dollars finding their way into projects to build exoskeletons, master-slave robot arms, biofeedback devices, and expert systems. For all the big bucks and high seriousness, the prevailing impression left by old cyborg technical papers is of a rather expensive kind of science fiction. Time and again, scientific reasoning melts into metaphysical speculation about evolution, human boundaries, and even the possibility of what Clynes and Kline call "a new and larger dimension for man's spirit." The cyborg was always as much a creature of scientific imagination as of scientific fact. It wasn't only the military that was captivated by the possibilities of the cyborg. The dream of improving human capabilities through selective breeding had long been a staple of the darker side of Western medical literature. Now there was the possibility of making better humans by augmenting them with artificial devices. Insulin drips had been used to regulate the metabolisms of diabetics since the 1920s. A heart-lung machine was used to control the blood circulation of an 18-year-old girl during an operation in 1953. A 43-year-old man received the first heart pacemaker implant in 1958. By the 1970s, the idea of an augmented human had entered the mainstream. Steve Austin, The Six Million Dollar Man, and his cohort Jaime Sommers, The Bionic Woman (with bionic limbs and a super-sensitive bionic ear), were popular heroes, their custom superpowers bought off the shelf like a digital watch. The cyborg had grown from a lecture-room fantasy into the stuff of prime-time TV."

"Think about the technology of sports footwear," she says. "Before the Civil War, right and left feet weren't even differentiated in shoe manufacture. Now we have a shoe for every activity." Winning the Olympics in the cyborg era isn't just about running fast. It's about "the interaction of medicine, diet, training practices, clothing and equipment manufacture, visualization and timekeeping." When the furor about the cyborgization of athletes through performance-enhancing drugs reached fever pitch last summer, Haraway could hardly see what the fuss was about. Drugs or no drugs, the training and technology make every Olympian a node in an international technocultural network just as "artificial" as sprinter Ben Johnson at his steroid peak."

"The cybernetics phase of cognitive science produced an amazing array of concrete results, in addition to its long-term (often underground) influence:"

"During the 1950s and 1960s most of the work which was called cybernetics tended to focus on control systems in engineering or on applications of the concept of feedback in fields ranging from mathematics to sociology. At the 1970 meeting of the American Society for Cybernetics in Philadelphia Heinz von Foerster sought to redirect attention to the original interests which had led to the founding of the field of cybernetics. In a paper titled "Cybernetics of Cybernetics" he made a distinction between first order cybernetics, the cybernetics of observed systems, and second order cybernetics, the cybernetics of observing systems."

"The main object of cybernetics is to supply adaptive, hierarchical models, involving feedback and the like, to all aspects of our environment. Often such modelling implies simulation of a system where the simulation should achieve the object of copying both the method of achievement and the end result. Synthesis, as opposed to simulation, is concerned with achieving only the end result and is less concerned (or completely unconcerned) with the method by which the end result is achieved. In the case of behaviour, psychology is concerned with simulation, while cybernetics, although also interested in simulation, is primarily concerned with synthesis. Most of the major developments in models and theories of artificial intelligence have taken place in the western world — mostly, indeed, in the US and Britain — and it was only relatively recently that "core developments", as opposed to more peripheral developments and applications, have spread over Europe and the Soviet Union."

"Now "cybernetics" is the term coined by Wiener to denote "steersmanship" or the science of control. Although current engineering usage restricts it to the study of flows in closed systems, it can be taken in a wider context, as the study of processes interrelating systems with inputs and outputs, and their structural-dynamic structure. It is in this wider sense that "cybernetics" will be used here, to wit, as system-cybernetics, understanding by "system" an ordered whole in relation to its relevant environment (hence one actually or potentially open)."

"Another scientific development that we find difficult to absorb into our traditional value system is the new science of cybernetics: machines that may soon equal or surpass man in original thinking and problem-solving. [...] In the hands of the present establishment there is no doubt that the machine could be used – is being used – to intensify the apparatus of repression and to increase established power. But again, as in the issue of population control, misuse of science has often obscured the value of science itself. In this case, though perhaps the response may not be quite so hysterical and evasive, we still often have the same unimaginative concentration on the evils of the machine itself, rather than a recognition of its revolutionary significance."

"The essence of cybernetic organizations is that they are self-controlling, self-maintaining, self-realizing. Indeed, cybernetics has been characterized as the “science of effective organization,” in just these terms. But the word “cybernetics” conjures, in the minds of an apparently great number of people, visions of computerized information networks, closed loop systems, and robotized man-surrogates, such as “artorgas” and “cyborgs.”"

"The meaning of the term "cybernetics" is today somewhat different from that used when Wiener, McCulloch, Rosenblueth, Bigelow and others used the Greek word "Kybernetes," or helmsmen, to describe an automatic computer... the definition, which I first gave in 1966: "Cybernetics describes an intelligent activity or event which can be expressed in algorithms. Algorithms, in turn, refer to a system of instructions which describes unambiguously and accurately an interaction which is equivalent to a given type of flux of intelligence and a subsequent, controlled activity. The development of cybernetics aims, among other things, at the design and reproduction of functions which are peculiar to intelligent organism.""

"The theory of information became the cornerstone of cybernetics because the latter deals with "the study of systems of any nature that are capable of receiving, storing and processing information and utilizing it for control"."

"Perhaps the most important single characteristic of modern organizational cybernetics is this: That in addition to concern with the deleterious impacts of rigidly-imposed notions of what constitutes the application of good "principles of organization and management" the organization is viewed as a subsystem of a larger system(s), and as comprised itself of functionally interdependent subsystems."

"As Alain Enthoven was himself to recognize, ‘you assume that there is an information system that will tell you what you want to know. But that just isn’t so. There are huge amounts of misinformation and wronginformation’. Thus, far from eliminating the Clausewitzian ‘fog of war’, cybernetic warfare itself generated ‘a kind of twilight, which, like fog or moonlight, often tends to make things seem grotesque and larger than they really are’."

"Some wiki engines try to represent functionality that's more CMS-like (e.g. complex workflows and access controls), while MediaWiki's functionality tends to be driven by the needs of open communities with minimal barriers to entry."

"MediaWiki is a useful tool for supporting group collaboration but when we apply it to the academic setting, we need to consider and adapt some features to match the needs of the classroom environment, which requires mandatory collaborative writing."

"In Germany, we have a famous children's TV show called "Löwenzahn". It starts with a time lapse sequence of a dandelion flower breaking its way through the asphalt. This is what I've always associated with the MediaWiki logo, technology (brackets) being merely the basis for the growth of something wild and beautiful which transcends it."

"MediaWiki (www.mediawiki.org/wiki/MediaWiki) is one of the best publishing wiki engines in existence."

"First released in 2002, MediaWiki is one of the top wiki engines and runs most of the wiki hosting sites. The name was a play on “Wikimedia,” and many people find it to be annoyingly confusing."

"MediaWiki is the most popular opensource software used for creating wiki sites."

"MediaWiki is not as easy to use as web-based services, but it does have quite good functionality."

"Clear your mind and build your collective offline memory using MediaWiki (http://mediawiki.org), the same software that powers Wikipedia."

"The main downside of publishing a site using MediaWiki is that it won't give you a great opportunity to use or improve your HTML skills."

"A notable irony of Wikipedia's popularity is that the editing process of its supporting technology, MediaWiki, is complex to learn. Editing Wikipedia pages requires significant investment to learn MediaWiki's unique and powerful code structure."

"MediaWiki is the most well-known wiki software because it is what runs WikiPedia. MediaWiki is simple to use and an excellent way to start collaborating on documentation or articles."

"MediaWiki makes it very easy both to track changes to the pages of their sites, and to revert to older copies of the pages."

"While there are many different wiki content-management systems available for free or fee, MediaWiki is one of the most robust and well-maintained systems available to wiki publishers."

"Computer science is no more about computers than astronomy is about telescopes."

"[Computer science] is not really about computers -- and it's not about computers in the same sense that physics is not really about particle accelerators, and biology is not about microscopes and Petri dishes...and geometry isn't really about using surveying instruments. Now the reason that we think computer science is about computers is pretty much the same reason that the Egyptians thought geometry was about surveying instruments: when some field is just getting started and you don't really understand it very well, it's very easy to confuse the essence of what you're doing with the tools that you use.""

"Software engineering is the part of computer science which is too difficult for the computer scientist."

"Starting when computer technology first emerged during World War II and continuing into the 1960s, women made up most of the computing workforce. By 1970, however, women only accounted for 13.6% of bachelor's in computer science graduates. In 1984 that number rose to 37%, but it has since declined to 18% -- around the same time personal computers started showing up in homes. According to NPR, personal computers were marketed almost exclusively to men and families were more likely to buy computers for boys than girls."

"The percentage of women working in computer science-related professions has declined since the 1990s, dropping from 35% to 26% between 1990 and 2013. According to the American Association of University Women, we can reverse this trend by removing negative connotations around women in computer science. Educators and parents must work together to help girls maintain their confidence and curiosity in STEM subjects. Professional women already in the field can become mentors, while men can help create a more inclusive workplace."

"Computer science... differs from physics in that it is not actually a science. It does not study natural objects. Neither is it, as you might think, mathematics; although it does use mathematical reasoning pretty extensively. Rather, computer science is like engineering; it is all about getting something to do something, rather than just dealing with abstractions, as in the pre-Smith geology."

"[Computers] are developing so rapidly that even computer scientists cannot keep up with them. It must be bewildering to most mathematicians and engineers... In spite of the diversity of the applications, the methods of attacking the difficult problems with computers show a great unity, and the name of Computer Sciences is being attached to the discipline as it emerges. It must be understood, however, that this is still a young field whose structure is still nebulous. The student will find a great many more problems than answers."

"Interviewer: Is studying computer science the best way to prepare to be a programmer? Bill Gates: No. the best way to prepare is to write programs, and to study great programs that other people have written. In my case, I went to the garbage cans at the Computer Science Center and I fished out listings of their operating system. You got to be willing to read other people's code, then write your own, then have other people review your code. You've got to want to be in this incredible feedback loop where you get the world-class people to tell you what you're doing wrong."

"The purpose of computing is insight, not numbers."

"The only generally agreed upon definition of mathematics is "Mathematics is what mathematician's do." which is followed by "Mathematicians are people who do mathematics." What is true about defining mathematics is also true about many other fields: there is often no clear, sharp definition of the field. In the face of this difficulty [of defining "computer science"] many people, including myself at times, feel that we should ignore the discussion and get on with doing it. But as George Forsythe points out so well in a recent article*, it does matter what people in Washington D.C. think computer science is. According to him, they tend to feel that it is a part of applied mathematics and therefore turn to the mathematicians for advice in the granting of funds. And it is not greatly different elsewhere; in both industry and the universities you can often still see traces of where computing first started, whether in electrical engineering, physics, mathematics, or even business. Evidently the picture which people have of a subject can significantly affect its subsequent development. Therefore, although we cannot hope to settle the question definitively, we need frequently to examine and to air our views on what our subject is and should become."

"Without real experience in using the computer to get useful results the computer science major is apt to know all about the marvelous tool except how to use it. Such a person is a mere technician, skilled in manipulating the tool but with little sense of how and when to use it for its basic purposes."

"Indeed, one of my major complaints about the computer field is that whereas Newton could say, "If I have seen a little farther than others, it is because I have stood on the shoulders of giants," I am forced to say, "Today we stand on each other's feet." Perhaps the central problem we face in all of computer science is how we are to get to the situation where we build on top of the work of others rather than redoing so much of it in a trivially different way. Science is supposed to be cumulative, not almost endless duplication of the same kind of things."

"I can’t be as confident about computer science as I can about biology. Biology easily has 500 years of exciting problems to work on. It’s at that level."

"My own feeling is this: mathematics and computer science are the two unnatural sciences, the things that are man-made. We get to set up the rules so it doesn't matter the way the universe works – we create our own universe... And I feel strongly that they are different, but I tried to convince Bill Thurston and he disagreed with me. My opinion though is I can feel rather strongly when I am wearing my mathematician's cloak versus when I am wearing my computer scientist's cap."

"Computer science is an empirical discipline. [...] Each new machine that is built is an experiment. Actually constructing the machine poses a question to nature; and we listen for the answer by observing the machine in operation and analyzing it by all analytical and measurement means available. Each new program that is built is an experiment. It poses a question to nature, and its behavior offers clues to an answer."

"Computer scientists have so far worked on developing powerful programming languages that make it possible to solve the technical problems of computation. Little effort has gone toward devising the languages of interaction."

"Computer science is neither mathematics nor electrical engineering."
