Rigel, analyste technique en informatique, je d\u00e9veloppe des logiciels pour une banque nord-am\u00e9ricaine. N\u00e9 en 1980, papa de deux formidables enfants, j\u2019ai la chance d\u2019avoir une vie de famille heureuse et bien remplie en France dans le d\u00e9partement de la Moselle. 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. J\u2019aime apprendre par moi-m\u00eame et d\u00e9battre de mes acquis pour les mettre \u00e0 l\u2019\u00e9preuve.
