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.
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.
The sciences do not try to explain, they hardly even try to interpret, they mainly make models. By a model is meant a mathematical construct which, with the addition of certain verbal interpretations, describes observed phenomena. The justification of such a mathematical construct is solely and precisely that it is expected to work.john von neumann
I hate flowers — I paint them because they're cheaper than models and they don't move!Georgia O'Keeffe
One advantage of exhibiting a hierarchy of systems in this way is that it gives us some idea of the present gaps in both theoretical and empirical knowledge . Adequate theoretical models extend up to about the fourth level, and not much beyond. Empirical knowledge is deficient at practically all levels.kenneth boulding
It is clear that the building of models is not a purely mechanical process but requires skill of a high order – not merely mathematical skill but a sensitivity to the relative importance of different factors and a critical, almost an artistic, faculty in the selection of behaviour equations which are reasonable, tentative hypotheses in explaining the behaviour of actual economies.kenneth boulding
Unless the fundamental categories of economics such as ‘property’ were to be redefined in a radically personal way the liberal rationalist curse which had established economics as a scientific discipline cut off from human interests would proliferate. Economic models … have failed to incorporate any meaningful index of individual benefit other than the original utilitarian one, … the index of increasing income or an increasing flow of commodities.john carroll
Physical processes alone will never completely explain the existence of the universe , life , and consciousness . Religious answers are just wishful thinking and wanton fabrication cast over a bottomless pit of ignorance . To explain their occult and mystical experiences , magicians are forced to develop models beyond the scope of materialistic or religious systems .peter j. carroll
The best models of English writing are Shakespeare and the Old Testament, especially the book of Job, the Psalms, the Proverbs, Ecclesiastes, and the Song of Solomon. ... In writing English the most important quality that you can acquire is style. It makes all the difference to anyone who reads what you write, whether you use the best phrases in the best way.aleister crowley
It is difficult to falsify the hypothesis of dark matter, because, as with Ptolemy's epicycles, true believers can always add additional arbitrary features and free parameters to overcome any conceivable difficulties that occur with the dark matter models.john moffat
I realize now how lucky I was, in the total absence of role models, to have only men to rebel against. Today's women students are meeting their oppressors in dangerously seductive new form, as successful congenial female professors who view themselves as victims of a rigid foreign ideology.camille paglia
Essentially, all models are wrong, but some are useful.
Children have more need of models than of critics.
A well-defined enterprise architecture (EA) is a blueprint for institutional modernization and evolution that consists of models describing how an entity operates today and how it intends to operate in the future, along with a plan for how it intends to transition to this future state. Such architectures are essential tools whose effective development and use are recognized hallmarks of successful organizations.
Enterprise architecture is the process of translating business vision and strategy into effective enterprise change by creating, communicating and improving the key requirements, principles and models that describe the enterprise's future state and enable its evolution. The scope of the enterprise architecture includes the people, processes, information and technology of the enterprise, and their relationships to one another and to the external environment. Enterprise architects compose holistic solutions that address the business challenges of the enterprise and support the governance needed to implement them.
Game theory can be defined as the study of mathematical models of conflict and cooperation between intelligent rational decision-makers.
We may recognize the subject of management cybernetics which is seen as a rich provider of models for doing Operations research.
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...
Ackoff (1962)... differentiates between iconic models, which use the same materials but involve changes in scale, analogue models which also involve a change in the materials used in building the model, and symbolic models which represent reality by some symbolic system such as a system of mathematical equations.
A people is but the attempt of many To rise to the completer life of one And those who live as models for the mass Are singly of more value than they all.Robert Browning
models can easily become so complex that they are impenetrable, unexaminable, and virtually unalterable.
