Summer School in Hist.and Phil. of Physics with Michel Janssen

August 4-8, 2014, University of Tübingen

In five lectures Michel Janssen will present five case studies illustrating a metaphor for theory change in modern physics. In prin- ciple, new theoretical structures in phys- ics, unlike arches and other architectural structures, could be erected without any scaffolding. After all, that is essentially how the four-dimensional formalism of special relativity, the curved space-times of general relativity, and the Hilbert space formalism of quantum mechanics are introduced in modern textbooks. Historically, however, such structures, like arches, were first erect- ed on top of elaborate scaffolding provided by the structures they eventually either partially or completely replaced. After briefly discussing prospects and limitations of the metaphor, he will examine five examples of arches and scaffoldings in the history of relativity and quantum theory.
