Conceptual models are best thought of as design-tools – a way for designers to straighten out and simplify the design and match it to the users' task-domain, thereby making it clearer to users how they should think about the application.
[S]cientists are not robotic inducing machines that infer structures of explanation only from regularities observed in natural phenomena (assuming, as I doubt, that such a style of reasoning could ever achieve success in principle). Scientists are human beings, immersed in culture, and struggling with all the curious tools of inference that mind permits […]. Culture can potentiate as well as constrain as Darwin's translation of Adam Smith's laissez-faire economic models into biology as the theory of natural selection. In any case, objective minds do not exist outside culture, so we must make the best of our ineluctable embedding.stephen jay gould
Holland's and Kauffman's work, together with Dawkins' simulations of evolution and Varela's models of autopoietic systems, provide essential inspiration for the new discipline of artificial life, This approach, initiated by Chris Langton (1989, 1992), tries to develop technological systems (computer programs and autonomous robots) that exhibit lifelike properties, such as reproduction, sexuality, swarming, and co-evolution.john henry holland
Yeah. And as Linus once said: most numerical problems today in pure CPU cycles are actually 3D games. … It's not "incorrect" to say that you want the result faster, even if that result doesn't match your theoretical models.linus torvalds
There are no surprising facts , only models that are surprised by facts; and if a model is surprised by the facts, it is no credit to that model.eliezer yudkowsky
The use of Enterprise Architectures is becoming increasingly widespread in the private sector. Borrowing insights from enterprise reference architectures developed during the last decade, IT vendors and companies belonging to specific industries are establishing reference data and process models advancing the standardisation of their businesses and creating a more integrated environment for their activities. Although public administrations share the same problem of non-standardisation, which is being magnified rapidly in a changing and demanding environment, little has been done so far in the direction of integration...
The successes of modern control theory in the design of highly accurate space navigation systems have stimulated its use in the theoretical analyses of economic and biological systems. Similarly, the effectiveness of computer simulation techniques in the macroscopic analyses of physical systems has brought into vogue the use of computer-based econometric models for purposes of forecasting, economic planning, arid management.
If the system exhibits a structure which can be represented by a mathematical equivalent, called a mathematical model, and if the objective can be also so quantified, then some computational method may be evolved for choosing the best schedule of actions among alternatives. Such use of mathematical models is termed mathematical programming.george dantzig
Treatment of the apparently whimsical fluctuations of the stock quotations as truly non stationary processes requires a model of such complexity that its practical value is likely to be limited. An additional complication, not encompassed by most stock market models, arises from the manifestation of the market as a nonzero sum game.richard arnold epstein
A charming fellow, and so clever: he models himself on me.herbert beerbohm tree
Remember that all models are wrong; the practical question is how wrong do they have to be to not be useful.george e. p. box
Essentially, all models are wrong, but some are useful.george e. p. box
The historian is looked upon as objective when he measures the past by the popular opinions of his own time, as subjective when he does not take these opinions for models. That man is thought best fitted to depict a period of the past, who is not in the least affected by that period. But only he who has a share in building up the future can grasp what the past has been, and only when transformed into a work of art can history arouse or even sustain instincts.georg brandes
In Stage I, divorces were not allowed, so men's [sexual] affairs did not put women's economic security in jeopardy; in Stage II, affairs could lead to divorce, so men's affairs did place women's economic security in jeopardy. We did not want political leaders who would be role models for behavior that would put women's economic security in jeopardy.warren farrell
The legends of fieldwork locate all important sites deep in inaccessible jungles inhabited by fierce beasts and restless natives, and surrounded by miasmas of putrefaction and swarms of tsetse flies. (Alternative models include the hundredth dune after the death of all camels, or the thousandth crevasse following the demise of all sled dogs.)stephen jay gould
Stale is stale and borrowed is borrowed, no matter how original your models may have been.robert silverberg
The best way to support dreams and stretch is to set apart small ideas with big potential, then give people positive role models and the resources to turn small projects into big businesses.
This making or imagining of models (not necessarily or usually a material model, but a conceptual model) is a recognised way of arriving at an understanding of recondite and ultra-sensual processes, occurring say in the ether or elsewhere.
[The] company’s Chief Information Officer (CIO) should guide the rationale behind the development of EA models. In particular, distribution of IT related information and knowledge throughout the organization is emphasized as an important concern uncared for. Secondly, the lack of architectural theory is recognized...
As the size of software systems increases, the algorithms and data structures of the computation no longer constitute the major design problems. When systems are constructed from many components, the organization of the overall system the software architecture presents a new set of design problems. This level of design has been addressed in a number of ways including informal diagrams and descriptive terms, module interconnection languages, templates and frameworks for systems that serve the needs of specific domains, and formal models of component integration mechanisms.
Here I had tried a straightforward extrapolation of technology, and found myself precipitated over an abyss. It’s a problem we face every time we consider the creation of intelligences greater than our own. When this happens, human history will have reached a kind of singularity a place where extrapolation breaks down and new models must be applied and the world will pass beyond our understanding.
Archetypes, color, and components will forever change how you build Java models. We build Java models with teams of developers. In our day-to-day mentoring, we develop and try out new ideas and innovations that will help those developers excel at modeling.
Some form of self-awareness is surely essential to highly intelligent thought... On the other hand, I doubt that any part of a mind can see very deeply into other parts; it can only use models it constructs of them.
Today, nearly all biologists acknowledge that evolution is a fact. The term theory is no longer appropriate except when referring to the various models that attempt to explain how life evolves. ... It is important to understand that the current questions about how life evolves in no way implies any disagreement over the fact of evolution.
models have a sell-by date. There are certain jobs I don't do anymore, like the young, sexy, cute things for teenagers, or even 25-year-old girls. I go in a different bracket now.heidi klum
