“Making connections” in the mathematics courses for engineers: the example of online resources for trigonometry
2018
International audience; This paper concerns the teaching of mathematics for future engineers, focusing on the theme of trigonometry. We claim that the use of trigonometry in engineering courses requires different kinds of connections: connecting different domains, different concepts, frames and registers. We use here the concept of connectivity, developed in the frame of e-textbooks analysis, to analyse online courses for future engineers in France. We evidence that these courses propose some connections; but their connectivity is not developed enough to meet the requirements of engineering courses.
Student Partners in Task Design in a computer medium to promote Foundation students' learning of mathematics
2018
International audience; A team consisting of three mathematics education teacher-researchers, four former Foundation students (called Student Partners, SPs), and two analytic assistants worked together to produce mathematical tasks in a computer medium for the mathematical learning of current Foundation students (FSs). We have explored the collaboration between the SPs and researchers, the processes and outcomes of task design, and the contribution of the collaboration to tutorial teaching of FSs. We seek insight into the learning of all concerned of mathematics, mathematics teaching, task design and personal-professional development. The project is ongoing. Here we introduce the project an…
A20 Sample preparation for whole-genome next-generation sequencing (NGS) of hepatitis C virus (HCV) routine RNA samples
2019
Abstract Next-generation sequencing (NGS) is a technique that can capture the variability of viral populations in transmission studies. The conventional sample preparation for NGS, based on amplicons, is a potential source of errors, derived from the variable affinity of specific primers for different viral variants and from irregular DNA polymerase efficiency. In this context, we propose a more reliable method for viral whole genome sample preparation, starting from nucleic acids obtained and stored with conventional procedures. Our goal was to obtain complete hepatitis C virus (HCV) genome sequences to subsequently perform extensive phylogenetic analyses. Additionally, we aimed to test th…
Reversing arrows: Duality
2021
What do you get reversing all arrows? The drawing ‘Duality’ is an homage to mirrors, classical art themes, and abstract mathematics.I’m looking for beauty in the arts and beauty in science. It’s a ...
La théorie des lignes parallèles de Johann Heinrich Lambert
2014
International audience; The memoir "Theory of parallel lines" (1766) by Johannes Heinrich Lambert is one of the founding texts of hyperbolic geometry, even though his author conceived it as an attempt to show that this geometry does not exist. In fact, Lambert developed that theory with the hope of finding a contradiction. In doing so, he obtained several fundamental results of hyperbolic geometry. This was sixty years before the first writings of Lobachevsky and Bolyai appeared in print. This book contains the first complete translation of Lambert's memoir as well as mathematical and historical commentaries.
A perspective on the contribution of Paul Mansion (1844-1919) to mathematical research

Fernand de Montessus de Ballore (1851-1923), centenaire 2023Bibliographie I (les publications de Fernand de Montessus, écrits sur la vie et l'oeuvre …
2022
L'année 2023 marquera le centenaire de la disparition du scientifique et ingénieur français Fernand de Montessus Ballore (1851-1923), considéré comme un des précurseurs de la sismologie moderne. Dans cette optique, il nous paraît important d'établir un corpus bibliographique sur la vie et l'oeuvre scientifique de ce savant. Fernand de Montessus a beaucoup publié, sur une période allant de 1884 à 1923. Ses travaux sont toujours régulièrement cités dans des articles de Géophysique ou de Sismologie, entre autres, mais aussi dans le domaine de l'histoire des sciences. Nous voyons donc qu'il nous faudrait lister l'ensemble des travaux de la main de Fernand de Montessus, puis les différents artic…
René Baire, Chambéry Juillet 1932
2022
Il y a quatre-vingt-dix ans, le 5 Juillet 1932, René Baire (1874-1932) décédait à l'hôpital de Bassens, près de Chambéry. Cette note rappelle cet événement et donne quelques points permettant de comprendre qui était René Baire.
Une présence dijonnaise aux origines du CNRS ? Paul Appell et André Job membres du Comité scientifique de la Fondation de Edmond Rothschild.
2019
Le mathématicien Paul Appell (1855-1930) et le chimiste André Job (1870-1928) entrent au Comité scientifique de la Fondation Edmond de Rothschild en 1921. André Job en est d'ailleurs le secrétaire général. Il se trouve que Paul Appell et André Job ont vécu à Dijon. Nous allons voir ce qui lie ces deux scientifiques à la ville de Dijon.
