Théétète d’Athènes (IVe siècle av. J.C.)

Mathématicien grec, néopythagoricien. Il est né vers 417, mort très jeune. Sa vie et ses travaux sont connus par les dialogues de Platon le Théétète et le Sophiste.

Il apporta une importante contribution à la théorie des irrationnels. Ce travail a été décrit dans le livre X des

Eléments d’Euclide. Certains pensent que c’est le travail le plus fin des Eléments.

On pense qu’il est aussi l’auteur de la théorie des proportions décrite dans le travail d’Eudoxe.

Il aurait été le premier à étudier l’octaèdre et l’icosaèdre.

On pense que le livre XIII des Eléments d’Euclide est basé sur son travail. Ces travaux seront repris beaucoup plus tard par Kepler, Euler, Descartes, Cauchy et Poinsot.
