I didn't like to down vote people, because I think that's not very mannerly or nice. I up voted almost everything, so if you didn't receive an up vote then there's probably something wrong with your answer.

(Temporary Notice)I was in isolation for over 16 months, 12 consecutive months without stepping away from the apartment building, from Covid and it had significantly impacted my academic performance. Please be aware that I might not think clearly as I should be in terms of the orthodox academia reasoning. I started to study CFTs and string recently with the help of my advisor, it confused me as an developing subject so the thoughts and the elaborations are favored.
