Models and Fiction
model fiction Walton make-believe
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...
Controlling Complex Phenomena with the Help of Opaque Models
complexity modeling epistemic opacity
2008/4/11
Simulations may manage to control complex phenomena while at the same time the models invoked remain epistemically opaque. Considering cases from astronomy and meteorology, it will be argued that simu...
Electromagnetic Models of the Electron and the Transition from Classical to Relativistic Mechanics
electromagnetic worldview classical electron
2008/4/11
This paper is part II of a trilogy on the transition from classical particle mechanics to relativistic continuum mechanics that one of the authors is working on. The first part, on the Trouton experim...
Dynamical Emergence of Instantaneous 3-Spaces in a Class of Models of General Relativity
Achronal 3-spaces in GR Distant simultaneity Endurantism
2008/4/11
The Hamiltonian structure of General Relativity (GR), for
both metric and tetrad gravity in a definite continuous family of space-times, is fully exploited in order to show that: i) the "Hole Argumen...
Constructible Models of Quantum Logics.
Quantum logic Quantum theory Abstract Algebraic Logic (AAL)
2008/4/10
We continue in this article the algebraic treatment of quantum sentential logics (Wilczek 2006). Notions borrowed from the field of Model Theory and Abstract Algebraic Logic (i.e., consequence relatio...
Classical nonlocal field models consisting of probability density functionals over functions defined everywhere on Minkowski space are constructed directly from a quantum field state, using functional...
This paper examines some counterexamples to Judea Pearl's theory of token-causation within his structural equations framework. It argues that it is possible to modify the theory in natural ways to ove...
Between Laws and Models: Some Philosophical Morals of Lagrangian Mechanics
Classical mechanics Lagrangian mechanics
2008/4/10
I extract some philosophical morals from some aspects of Lagrangian mechanics. (A companion paper will present similar morals from Hamiltonian mechanics and Hamilton-Jacobi theory.) One main moral con...
