the way it is?
I have very little reason to accept yours people theory as it base on craziness. In fact, it was state by Newton 2nd Law that F = Gm1m2/r^2, yet gases rises to certain heigth and then stop. When you can't even realised something as simpleton there rise the possibility that yours geormetric conception of such matter states is not reliable and that it success is base solely on the kindness of nature and experience base on actual practices. Therefore, I don't think your people should be teaching as it base too much on personal promotion and "that the way it is," hey, I might be Vietnamese and my country is "not very good" and you might be the "superior American or European" but I have very little respect for you and yours people for what they have or have not taught me. And that just base on science. Nevertheless, I still have some doubt that I am better equipe to scientifically answer such inquiry than yours superior race.
