Pastur's experiment was to test the theory of spontanious generation (that living things can come from nonliving things) by putting boiling broth in some flasks and leaving some open and some sealed. The conclusion he drew from this is that livng things can only "appear" on the broth if they are let in. They do not come from the broth.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
