:sigh: a scientist of politics, yes. a science is simply a study, and a scientist is simply one who studies. your science does not relate to this chemical/biological science that is being discussed however.
a Theologist is one who studies God or other Ultimate Wills, though typically it is the Judeo-Chritian God that is most accepted, as "Theo" means roughly "One most in charge"... note the "One"
Not quite. "Science" is a method. And "scientists" are those who employ that method.
