Axis interdisciplinarity in History & Philosophy of Science

Seminar of the PhDs Students of SPHERE

Coordination : Justin Gabriel, Edgar Lejeune et Nicolas Michel, (Université Paris Diderot, SPHERE)

On Mondays, 9:30am – 12:30am, Room 631B

Date Theme Organisation
09/10/2018 Modern formulas in the commentary of ancient mathematical texts, a telling element P. Chaigneau
Starting from the case of the edition of a Babylonian mathematical procedure by several scientists in the middle of the twentieth century, I would like to show how the modern mathematical formulas appearing in the commentaries to explain the ancient text, far from constituting transparent readings, concentrate numerous tacit assumptions underlying the interpretation. They are thus a sort of historiographical revelation that should be handled with caution at a publishing company. We will evaluate with the audience the possibilities of generalization and circumvention.

08/01/2019 Paper operations S. Hijmans, J. Gabriel et A. Reynaud
From the concept of "paper tools", developed by Ursula Klein, we will deal with the question of the manipulation of diagrams in chemistry, physics and mathematics. Based on the development of molecular formulas in the 19th century, Klein argues that these representations are comparable to laboratory tools rather than objects of study : just like laboratory instruments, diagrams can be manipulated to study indirectly objects, give results that confirm or refute theories, and open up new perspectives. This idea of ​​operations or manipulations that are done on paper (or other material supports) will allow us to take a particular look at the diagrammatic representations found in the different sciences and to question the boundary between theoretical practice and experimental practice. In particular, we will ask to what extent we can apply the notion of operations on paper, forged on the basis of examples from chemistry, in the case of mathematical figures and diagrams used in particle physics.
08/02/2019 What makes proof in didactics, history of science and philosophy of science ? S. Hijmans, H. Chekir, B. Duchemann

12/03/2019 Rewritings, reelaborations, reformulations N. Michel
Will be presented some key texts of what has been called for some decades the social history of mathematics (Goldstein, Ehrhardt, Schappacher), its inscription in what I think is the evolution of the history of science (as a discipline ) in general, but also one of its limits and some of its current issues, especially when it comes to taking into account the materiality of scientific practices.
09/04/2019 Intellectual technologies and algorithms. The grid and the list as indices of actors’ reasoning A. Remaki et E. Lejeune
Mathematicians and historians use techniques to produce knowledge. These techniques are the result of a technology, writing, which allows just a whole lot of ways to organize the world on written support. For example, the list allows classification, and thus could be analyzed among Mesopotamians as an indispensable tool for the development of the administration, both men and goods. The painting is another way of synthesizing representations, and thus of classifying, of ordering observations, results or data. These intellectual technologies, which allow a memorization of the intellectual operations as much as a synthesis of scattered elements, are vectors of science as much as scientificity, but they are also tools which are transmitted within the scientific communities. They can still be the vector of problem-solving methods, and are a great object for the historian of science who is interested in modes of reasoning and algorithms.
After a quick presentation of the pioneering work of Jack Goody and Daniel Bell on intellectual technologies, we will take a closer look at the changes involved in the application of new intellectual technologies to problems already known by the actors, in mathematics and history.
