On the occasion of the Fête de la Science held at the Exploradôme (Vitry-sur-Seine) on Saturday, October 11, 2025, Clelia Crialesi (Marie Skłodowska-Curie Postdoctoral Fellow) and Clément Cartier (PhD candidate, Université Paris Cité – SPHERE) are offering a workshop entitled “Comment calculait-on au Moyen Âge”? This workshop invites the public to explore a different way of conceiving and handling arithmetical operations, drawing on a Latin manuscript copied in the 13th century (Paris, Sainte Geneviève, 1043).
Interview for IPM
by By Isabel Inzunza Gomez and Guillermo Ruz Troncoso
In this interview, Clelia Crialesi, a Marie Skłodowska-Curie Fellow, delves into her pioneering research project, MUCH, funded by the European Commission. Focusing on the philosophical and mathematical intersections of 14th-century Italy, Clelia explores themes such as quantity, abstraction, and the unknown, revealing their significance in shaping both medieval and modern thought. She also discusses her forthcoming book, Mathematics and Philosophy at the Turn of the First Millennium: Abbo of Fleury on Calculus, shedding light on the rich interplay between arithmetic, theology, and natural philosophy. From uncovering the intellectual landscape of premodern Europe to reflecting on the challenges and opportunities in her field, Clelia offers a compelling glimpse into her work and its lasting impact on the study of the history of philosophy and mathematics.
