Curieux de tout, car pour moi tout est curieux. J\u2019ai ce besoin visc\u00e9ral d\u2019observer, d\u00e9cortiquer, d\u00e9monter, comprendre et apprendre. Tout est source de d\u00e9couverte et d\u2019\u00e9merveillement. Il \u00e9tait donc logique qu\u2019un jour je me tourne vers les myst\u00e8res de l\u2019univers. F\u00e9ru d\u2019astrophysique, de physique, et d\u2019astronomie, je n\u2019en suis pas moins un parfait amateur.
