 :I will write this once: lists are NOT places for listing possibly, even probably notable people who dont have articles yet, unless you take the time to add at least one reliable source indicating the persons notability in science, and their status as a brazilian national, or resident. If anyone wants to request an article be written on one of these people, there are places on WP to request articles. Lists are for confirmed notability only, otherwise it becomes a directory and open to self promotion.
