In trying to maintain the flow of the conversation I responded with another question, did you note the (?) That is not a statement, that's a question. And in my post it was a specific question in what context the term was used, to which I never received an answer except from you.. String theory is part of quantum theory, including quantum gravity, so any strides in quantum theory would also have to affect string theory and vice versa. Except I never called it mathematical strides. Nevertheless, I am pleased that now this snafu has been cleared up, we are in agreement.
