1.The problems/challenges that you have to face daily are mostly related to code issues with the physics itself?
2. Is there room to improve our knowledge of fundamental physics while working on it?
2. Do you enjoy doing it? why?
I'm asking this because I'm considering working on numerical relativity but, although I really enjoy general relativity, I'm afraid that the problems that I will have to solve working in that field are mostly related to numerics and coding.
