I'm interested in mathematics and technology as dimensions of world-ordering processes.

My first monograph, The World of Maria Gaetana Agnesi: Mathematician of God, explores the world in which Agnesi lived and wrote her book of mathematics, the first authored by a woman (1748). Using the lens of microhistory, I reconstruct the conditions within which she emerged as a child prodigy in 1720s Milan, and was trained in natural philosophy and mathematics during the 1730s. At a time in which women could not access universities, Agnesi learned about the most recent developments of calculus and went on to write the first systematic presentation of its techniques. This was a mystifying choice for her contemporaries and, to understand it, we have to familiarize ourselves with Gaetana’s intense devotion, and the value she gave to a well-trained intellect in religious life. In her book, Agnesi argued for the significance of infinitesimal calculus as an intellectual exercise, rather than a set of useful tools for measuring and controlling reality. This position was distant from those of most contemporary mathematicians, and gave her book a distinctive style and structure. I thus argue for the social shaping of mathematical knowledge: in this case, its essential relation to specific religious practices and to the notion of “attention”. I also argue for the role of the Catholic Church in Agnesi’s career, and for the relevance of a revised notion of “Catholic Enlightenment” to reconstruct the development of eighteenth-century science in Europe. Finally, I trace the decline of the phenomenon of the Italian “women philosophers” — women who, like Agnesi, had entered the world of higher knowledge in the first half of the century. By the early 1800s, the establishment of new scientific theories had made it abundantly clear that the “female mind” was not suitable to the sciences, least of all to mathematics.

My second monograph, Reactionary Mathematics: A Genealogy of Purity reconstructs the emergence of modern mathematics during the first half of the nineteenth century as, at once, a mathematical and a political transformation. I focus on the Kingdom of Naples, where this change is visible early on, and takes a radical form. Here, between 1790 and 1830, leading scientific institutions rejected as untrustworthy the hegemonic mathematics of the time, French analysis, and in its place consolidated, legitimated, and put to work a different mathematical culture. I argue that theirs was a mathematical resistance, which implied a complete reorientation of mathematical practice. Over the unrestricted manipulation and application of algebraic algorithms, Neapolitan mathematicians called for a return to Greek-style geometry and the preeminence of a newly defined “pure mathematics.” For all their apparent backwardness, they were arguing for what would become crucial features of modern mathematics: its voluntary restriction through a new kind of rigor and discipline, and the complete disconnection of mathematical truth from the empirical world—in other words, its purity. The Neapolitans, I argue, were reacting to the widespread use of mathematical analysis in social and political arguments. Theirs was a reactionary mathematics that aimed to technically refute the revolutionary mathematics of the Jacobins. During the Restoration, the expert groups in the service of the modern administrative state reaffirmed the role of pure mathematics as the foundation of a newly rigorous mathematics, which was now conceived as a neutral tool for modernization. What emerges vividly, is that producing mathematical knowledge was equally about producing certain forms of social, political, and economic order.
