Org. Eleonora Andriani, Nick Jacobson, Laure Miolo, Samuel Gessner, Matthieu Husson
Observatoire de Paris, 77 avenue Denfert-Rochereau, 75014 Paris.
This seminar is open to the public, however due to the current sanitary restrictions it will be accesible only through virtual participation. If you want to participate in this way please register at least 48h in advance by writting a message to pascale.baudoin@obspm.fr. We will send you the contact information.
We hope to be able to welcome colleagues in Paris Observatory as soon as possible!
Argument
During the last two years the “readings and research on the Alfonsine corpus” seminar devoted itself to a close up study of the mathematical practices of Alfonsine astronomers. Through an analysis of primary sources attentive to their materiality we have focused among other things on: the kind of numbers and quantities they shaped, their relation to computations, rounding and interpolation, their use of diagrams and instruments, their use of standardized procedures, or their attitude toward proofs and justification. Examining the clues left by astronomers in their manuscripts (marginal notes, punctuations marks…) we have analysed different layers of mathematical practices, ranging from numbers and quantities to procedures and argumentation, in their own sake but have also addressed the issue of how they were articulated in order not only to provide solutions to astronomical problems but also to reveal self reflexive understandings and evaluations of these astronomical problems.
This year seminar will be devoted to harvest the fruits of this collective work and the team have selected four specific case studies around which article will be written by subgroup and collectively discussed. Five session will be devoted to each case study.
