This seminar examines a range of theoretical and methodological approaches to quantification in the history of science and science and technology studies (STS). Historical texts will survey the rise of quantification across scientific disciplines and in various forms of governance. As a group, we will consider what kinds of knowledge and forms of governance are produced through quantification, how something (or someone) becomes quantifiable, and how quantitative objects or practices can be analyzed as historical or ethnographic sources. Students will have the opportunity to explore how an analysis of quantification might be relevant to their own research.
