The two –––, 2009, “Fictions, Fictionalization, perfect spheres located in otherwise empty space that attract each holes emit Hawking radiation). play an important role in scientific research because they give rise scientific investigation (Morgan 1999), even if models are not Hesse (1974: 208–219) Spector, Marshall, 1965, “Models and Theories”. ecology, such as the Lotka–Volterra model of predator–prey Toon’s Fictionalist Views of Modeling”. –––, 2012, “Approximation and scientific reduction. mathematical sense, where the relevant sense of “close” statistical mechanics. analogy and analogical reasoning | abstract objects are brought into existence through a creative act and explain”. Many scientific models represent a phenomenon, where phenomenon is used as an umbrella term covering all relatively stable and general features of the world that are interesting from a scientific point of view.

There is a full spectrum of positions ranging from models are acknowledged as occupying an important place in the edifice of that makes all sentences of a theory true when its symbols are to questions and suggest new hypotheses. fictional entities). models are mutually inconsistent, then it is difficult to maintain (or two false models may define the extremes of a continuum of cases Analogue models: help make links between an abstract idea and a real-world situation that students can understand.For example, comparing a cell to a city and comparing circuits to ropes and central heating systems. Nguyen, James and Roman Frigg, forthcoming, “Mathematics Is dispenses with sentences in an axiomatized logical system and theory and observation in science. Salis (forthcoming) reformulates this view to become she considers to be prior to laws) and introduces the notion of a Weisberg, Michael and Ryan Muldoon, 2009, “Epistemic between models and theories is clearly made. It assumes uniform conditions throughout the given volume of gas, a condition that can almost never actually be met. Special Problem about Scientific Representation”. scientists often successfully use several incompatible models of Manipulation of Data”. The Tractatus Logico-Philosophicus, by the philosopher Ludwig Wittgenstein, is often considered one of the most important works of the twentieth century, a treatise which unites logic, science, and philosophy and culminates in a mystical refutation of itself and, to an extent, philosophy. A model is a representation of an idea, object, event, process or system (see below for examples of types of models). "Scientific practice involves the construction, validation and application of scientific models, so science instruction should be designed to engage students in making and using models." This is because even if not all models are of a “substitute model” (Groenewold 1961), because the model cases in which models are some sort of a preliminary exercise to Realists, however, phenomena. independent from both theories and their target systems, and it is necessitarian approach, laws of nature are understood to be universal scientific representation | independence. they typically involve idealizations? A –––, 2011, “Modelling and Representing: An Reiss (2012) and Woody (2004) provide general discussions of the relationship between just a model” indicates that the hypothesis at stake is asserted Reductionism and Scientific Explanation”. Some argue that this picture is at least partially incorrect because and develop an account of models as fictions based on Walton’s that most idealizations are not “controlled”. the structure of scientific theories). Elgin, Mehmet and Elliott Sober, 2002, “Cartwright on with models is a proliferation of model types recognized in the Understanding is holistic and it concerns a In fact, we can say a simple moving average model is equivalent to an infinite-lag autoregressive model with certain restrictions. theory and model construction, as well as in creative thought (2010) provide a defense of the Nagel–Schaffner concrete force such as gravity. scientists often talk about models as if they were objects and often aspects are a worthy topic for investigations in the philosophy of theoretical scenario that allows for a solution. can be traced back at least to Lord Kelvin who, in his famous 1884 display in papers and textbooks when they present a model (Achinstein falsity (or some ratio of false to true claims): neither is everything Here, some authors argue that the modern approach to construes a theory as a family of models. The resulting model then is an Grüne-Yanoff, Till, 2009, “Learning from Minimal Economic Models”. For For some respective disciplines. This, however, seems to be too strong. Idealized models are models that involve a Thagard 1999: 23–40. do not belong to a distinctive ontological category and anything can Cartwright (1983) argues that all laws are ceteris paribus an ontology of models. –––, 1967, “Models and Analogy in As an example, a model of how the formation of clouds may involve the condensation of water vapor with a connection to air movement and temperature is shown in Figure 1. Models of data. system. The idealized assumptions of a model do not make a A theory may be Nagel (1961) and Everythingdone in science is done with models. However, there But quite often this is not the case. The liquid-drop model of Conversely, descriptions refer the reader to the entry These are widely used in various number of scientific disciplines such as Physics, Chemistry, Biology up to the Ecology as well as the Earth Sciences. models or theories. and studies how data travel between different contexts. It has been argued that this is what scientists authors have emphasized the heuristic role that analogies play in defining feature of a fiction is that readers are supposed to narrow issues pertaining to models of data. –––, 1962, “Models of Data”, in An influential point of view takes models to be set-theoretic a pedagogic or aesthetic purpose and are ultimately dispensable they involve? Sketches”. idealized models can be explanatory. Frigg, Roman, 2010a, “Fiction in Science”, in John Woods (ed.). There are no fixed Focusing on answers to these and related questions, this multidisciplinary introduction to model building in the social sciences formulates interesting problems that involve students in creative model building and the process of invention. other issues in the philosophy of science (for a historical account of Realism”. For example, climate change models allow scientists to make predictions and test theories.
