A Material Culture of Microphysics. First a description is given of the uncomfortable predicament in which the Kuhnian tradition finds itself in the past two decades. It is then explained how Galison distinguishes a layered structure in the practice of modern particle physics. Physics as a practice consists of three relatively autonomous levels: the experimental level, the instrumental level and the theoretical level. This paper focuses mainly (but not exclusively) on the instrumental level in particle physics. Subsequently an analysis is given of Galison's metaphor of the wall, which Galison offers as an alternative to the Kuhnian image of paradigms and scientific revolutions. Galison's model is also compared with Laudan's reticulational model of the evolution of scientific research traditions. To conclude, an analysis is made of Galison's attempt to solve the incommensurability problem
