Diagnosing Disagreements: The Authentication of the Positron 1931 – 1934

This paper bridges a historiographical gap in accounts of the prediction and discovery of the positron by combining three ingredients. First, the prediction and discovery of the positron are situated in the broader context of a period of ‘crystallisation’ of a research tradition. Second, the prediction and discovery of the positron are discussed in the […]

Two kinds of exploratory models

I analyse the exploratory function of two main modelling practices: targetless fictional models and hypothetical perspectival models. In both cases, I argue, modelers invite us to imagine or conceive something about the target system, which is either known to be non-existent (fictional models) or just hypothetical (in perspectival models). I clarify the kind of imagining […]

Perspectival Modeling

The goal of this article is to address the problem of inconsistent models, and the challenge it poses for perspectivism. I analyse the argument, draw attention to some hidden premises behind it, and deflate them. Then I introduce the notion of perspectival models as a distinctive class of modeling practices, whose primary function is exploratory. […]

Simplified Models: a New Perspective on Models as Mediators

We introduce a novel point of view on the “models as mediators” frame- work in order to emphasize certain important epistemological questions about models in science which have so far been little investigated. To illustrate how this perspective can help answer these kinds of questions, we explore the use of simplified models in high energy […]
