I have faced a couple of guys in the engineering PF that base all their analyses in their virtual experience in a company. No analytical demonstrations, no numbers, no concepts, only words and curriculums. I want let you know, PF administrators, that young people like me get dissapointed with these behaviors, because when one is young one looks for the proof of everything, looks for the insight, not for someone telling you that you should believe in what is he saying because he has a lot of experience. What I mean is that I am not going to spend a lot of time showing the thing for having afterwards a guy throwing everything to the trash by means of nothing. And this is gonna cause that the Mech&Eng forum is gonna be a place of OLD gurus, not a place for the knowledge and learning. PS: Those who know what I am thinking about know who is included in the list or not.
