Des conjectures aux preuves Construction des concepts mathématiques Journée d'études mathématiques
organisée en l'honneur de Gilbert Arsac |
|
"Aux périodes d'expansion, lorsque des notions nouvelles sont introduites, [il règne] une période de défrichement plus ou moins étendue, pendant laquelle dominent l'incertitude et la controverse. [...] la génération suivante peut alors codifier [...] élaguer,asseoir les bases, [...] à ce moment règne de nouveau alors sans partage la méthode axiomatique, jusqu'au prochain bouleversement qu'apportera quelque idée nouvelle" Le titre de cette journée rend compte d'une spécificité du travail mathématique : au cours du travail de recherche, avant la phase d'axiomatisation, les concepts se précisent dans l'explicitation progressive des propriétés qui les caractérisent et qui sont nécessaires pour démontrer les conjectures à leur propos. Cette spécificité des mathématiques est aussi un enjeu de leur apprentissage. C'est à l'étude de quelques moments de ce travail mathématique que vous êtes invités. 9h Evolution de l'utilisation de concepts mathématiques par la physique Cette journée est organisée en l'honneur de Gilbert Arsac par quelques collègues qui ont souhaité lui rendre cet hommage pour le travail important qu'il a accompli dans les divers domaines qui lui ont tenu à coeur au cours de sa carrière : les mathématiques avec la théorie des groupes, les problèmes d'apprentissage des mathématiques avec la didactique. Pour ces derniers, les mathématiques savantes sont une référence incontournable comme Gilbert Arsac lui même le montrera. C'est cette efficacité de l'approche mathématique des questions d'apprentissage qui ont guidé son action lorsqu'il était directeur de l'IREM et en tant que chercheur en didactique. Organisation : IREM, IGD (Institut Girard Desargues), LIRDHIST (Laboratoire Interdisciplinaire de Recherche en didactique et histoire des sciences et techniques) avec le soutien du Département de premier cycle, UFR de mathématiques |

The TSG-12 activities will encompass the following issues: I. The importance of explanation, justification, and proof in mathematics education; These issues will be considered from the following points of view: (a) Historical and
epistemological, related to the nature of mathematical proof
and its functions in mathematics in a historical
perspective; discussions on the different issues. |

Disourse on the method René Descartes |
Web Archives Kepler sphere packing problem |
"Thus my design is not here to teach the Method which everyone should follow in order to promote the good conduct of his Reason, but only to show in what manner I have endeavored to conduct my own. Those who set about giving precepts must esteem themselves more skillful than those to whom they advance them, and if they fall short in the smallest matter they must of course take the blame for it." (Descartes 1637) ![]() Images of Mathematicians on Postage Stamps |
Kepler's problem consists of deciding the most efficient way to pack equal-sized spheres in a large crate. Should each sphere sit right on top of the one beneath? Or should it be arracnged so that the spheres in each higher layer sit in the hollows formed beneath? Kepler believed that for a very large crate, the orange-pile arrangement is more efficient but was unable to prove it.

Historia-Matematica is a virtual forum for scholarly discussion of the history of mathematics in a broad sense, among professionals and non-professionals with a serious interest in the field, archived at Why Euclid gives geometric constructions in Book II that one might well expect to be postponed until after the general theory of proportion was developed, a thread begun by Roger Cooke: Euclid, Book II (14 Mar 1999) See Heinz Lueneburg's March 23 post, offering a link to dvi files in German from his number theory class, which draws on Euclid's Books VII, VIII, and IX. |
