Abstract

In the previous chapter we looked at the historical roots of scientific models. We will now turn to their contemporary use and view them from a philosophy of science perspective. As a starting point for this discussion we will specify what we actually mean by models, and discuss the different classes of models that exist. In order to broaden the concept and connect it to other concepts within science, we will relate modelling to phenomena and theories, and also analyse the relation between simulations of models and experiments. These notions will all be tied together, and made concrete in a worked example, where we show how a model typically is constructed. Lastly, we will try to draw conclusions about desirable properties of models, and discuss the dangers of modelling.

The name of the movement derives from the French word positif which roughly means “imposed on the mind by experience”.

This is a condensed and simplified account of the dynamic debate about the concept of unity that took place within the logical positivist movement, see e.g. the debate between Neurath and Kaller in a series of papers in the journal Philosophy and Phenomenological Research in 1946.

This relates to the philosopher Daniel Dennett’s concept of real patterns, that describes how we as humans find patterns in nature at the level on which they have the largest predictive power. Dennett, D. (1991) Real Patterns, The Journal of Philosophy, 88.

A contributing cause might be that Bohr’s model of the atom is easier to comprehend and relate to compared to the quantum mechanical description, which doesn’t describe any actual orbits, but instead provides a probabilistic description, which to each point in space assign a probability of finding an electron in that location.
