Within the social sciences, the standardized notion of representation refers to knowledge expressed through language and sourced from supra-individual thought processes. This notion underscores the social foundation of knowledge while minimizing its inherent material and symbolic foundations, without which it cannot be wholly understood. The article argues that the circulation of heterogeneous inscriptions underpins the elaboration of representations. To demonstrate this, I analyze practices intended to improve a therapeutic treatment for kidney stones and show how scientists place a series of objects, animals, models, texts, and so on in circulation, eventually transformed into the mathematic representation of a treatment.
