I bet you have never written a scientific paper or never have read one, judging from your childish grammar mistakes.
first of all , when trying to call out someones grammar - try not make a grammatical error yourself.
I have not been in space to see myself that the world is round, but I know it to be. So again my little little friend- these papers are published. In the English language it means you have finished writing it,submitted it to be published and it got accepted. all that research was done prior to it being published...
BTW yes I never bother with grammar, punctuations , sentence structure etc on forums.. I don't even bother capitalizing ...
BUT I shzit for sure comprehend the meaning of published work vs still freaking writing a paper
now carry on Sha gua
. I like the Iranian youth- they like the US too . let's hope your leaders walk away from a nuclear weapons program..and accept the great deal being given to them by others.
