In science, nothing is ever 100% proven.

كل ماهو غير مستحيل فهو ممكن

I'm not a science fiction writer, I'm a physicist.

Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest.

They basically ask their engineers to volunteer some probability figures, then they take the average. This is not science. This is voodoo,

No matter how beautiful the theory, one irritating fact can dismiss the entire formulism, so it has to be proven.
