  • La conjecture de Syracuse s’énonce ainsi : quel que soit le nombre que l’on choisisse au départ, on finira par tomber sur 1.
    L’énoncé de la conjecturePrenez un nombre entier positif, et appliquez lui le traitement suivant :
    s’il est pair, vous le divisez par 2;s’il est impair, vous le multipliez par 3 et vous ajoutez 1.Vous obtenez alors un nouveau nombre, sur lequel vous répétez la procédure. Et ainsi de suite, pour fabriquer une séquence de nombres.Mettons que je parte du nombre 7, voici la séquence que j’obtiens :7,22,11,34,17,52,26,13,40,20,10,5,15,16,8,4,2,1,4,2,1,4,2,1,…

  • Mudskippers are members of the subfamily Oxudercinae (tribe Periophthalmini), within the family Gobiidae (Gobies). They are completely amphibious fish, fish that can use their pectoral fins to walk on land. Being amphibious, they are uniquely adapted to intertidal habitats, unlike most fish in such habitats which survive the retreat of the tide by hiding under wet seaweed or in tidal pools. Mudskippers are quite active when out of water, feeding and interacting with one another, for example to defend their territories.
