Summary

[edit]
Description
Français : Un exemple exposé par Poincaré pour illustrer la notion de chaos : si on envoie un faisceau lumineux sur une sphère réfléchissante, la différence d'angle si on déplace d'un dixième de degré la source, le rayon réfléchi peut changer totalement de direction. Si on place une seconde sphère, l'effet est encore plus marqué.
