Geometry(ies) at Collège Stanislas

Emmanuel Royer gave two lectures on the theme of geometries. One on November 19 for second and first-year students focused on the history of Euclid’s fifth postulate and the (long) birth of so-called non-Euclidean geometries. The other, aimed at final-year students and linked to the teaching of philosophy, also started from Euclid’s fifth postulate to invite reflection on the axiomatization of mathematics.

The topics presented were based on the document available for download and a short bibliography of the texts used to prepare these presentations is available at the end of the text available for download (which is not the text of the lectures)
