Representation has been one of the main themes in the recent discussion of models. Several authors have argued for a pragmatic approach to representation that takes users and their interpretations int...
Experimental engineering models have been used both to model general phenomena, such as the onset of turbulence in fluid flow, as well as to predict the performance of machines of particular size and ...
Models in Fluid Dynamics
Fluid Dynamics Models
2008/4/15
In this paper, I would like to show that considering technological models as they arise in engineering disciplines can greatly enrich the philosophical perspective on models. In fluid mechanics, (at l...
According to a widespread view of scientific modelling, the false ‘prepared descriptions’ and theoretical laws that scientists write down when they model a system do not represent that system directly...
Models as a Tool for Theory Construction: Some Strategies of Preliminary Physics
Strategies of Preliminary Theory Construction
2008/4/15
Theoretical models are an important tool for many aspects of scientific activity. They are used, i.a., to structure data, to apply theories or even to construct new theories. But what exactly is a mod...
Fundamental theories are hard to come by. But even if we had them, they would be too complicated to apply. Quantum chromodynamics (QCD) is a case in point. This theory is supposed to govern all strong...
Models and Modals

2008/4/15
Pragmatists recommend that in approaching a problematic concept in philosophy, we should begin by examining the role it plays in the practical, cognitive and linguistic lives of the creatures who use ...
Models are generally used by scientists to obtain predictions and to provide explanations about phenomena. Their predictive and explanatory power is generally thought of as depending on their represen...
Models and Fiction

2008/4/15
Most scientific models are not physical objects, and this raises important questions. What sort of entity are models, what is truth in a model, and how do we learn about models? In this paper I argue ...
Matrix models as non-local hidden variables theories
hidden variables theory quantum gravity
2008/4/15
It is shown that the matrix models which give non-perturbative definitions of string and
M theory may be interpreted as non-local hidden variables theories in which the quantum
observables are the e...
MATHEMATICAL MODELS IN SCIENCE: A DEBATE ABOUT ONTOLOGY
Mathematical realism Indispensability argument
2008/4/15
Some philosophers of mathematics argue that the role of mathematical models in science is merely representational: when scientists use mathematical models they only believe that they are adequate repr...
I survey a broad variety of models with an eye to asking what kind of model each is in the following sense: in virtue of what is each of them regarded as a model? It will be seen that when we classify...
Imaginary-Constitutives. The Ontology of Scientific Models.
models semantic view models-as-mediators analogies
2008/4/14
Hitherto, there have been two approaches towards models in the philosophy of science. One could be called “formalistic” and the other one “methodological”. The first coincides with the so-called seman...
How Do Microscopic Models of Financial Markets Explain?
Scientific explanation complex systems econophysics
2008/4/14
Financial theory is in trouble. Market crashes and high volatility are only too familiar to everyone, although the standard theories predict that they hardly ever occur. According to the well-known an...
Goethe to van Gelder: Comments on "Dynamical Systems" Models of Cognition
dynamical systems computational models
2008/4/14
The "dynamical systems" model of cognitive processing is
not an alternative computational model. The proposals about
"computation" that accompany it are either vacuous or do not
distinguish it from...
