Je rêve d'un jour où l'égoïsme ne régnera plus dans les sciences, où on s'associera pour étudier, au lieu d'envoyer aux académiciens des plis cachetés, on s'empressera de publier ses moindres observations pour peu qu'elles soient nouvelles, et on ajoutera " je ne sais pas le reste". Évariste Galois (1811-1832)

(I dream that one day selfishness will no longer reign on Sciences, and that we will get together to study, instead of sending academicians sealed envelopes, we will hasten to publish in details all of our observations hoping they are new ones, and we will add "I do not know what follows".)
