Models as Mediators discusses the ways in which models function in modern science, particularly in the fields of physics and economics. Models play a variety of roles in the sciences: they are used in the development, exploration and application of theories and in measurement methods. They also provide a mechanism for using scientific concepts and principles to intervene in the world. The editors provide a framework that covers the construction and function of scientific models, and explore the ways in which they enable us to learn about both theories and the world. The contributors to the volume offer their own individual theoretical perspectives and cover a wide range of examples of modeling. These papers provide ideal case study material for exploring both the concepts and typical elements of modeling methods, using analytical approaches from the domains of philosophy and history of science.
