I am taking an advance course in Computer Science so the class size is pretty limited (8 to be exact). The faculty is very senior and well respected in the field. For past few lectures, I have been asking questions that make the faculty a little uncomfortable which I can guess from the way the answers are given (I am also on a psychology class :-) )
For example, to understand a concept, I say "why X has been used ?". He tries his best to answer "because of A,B,C reasons". During this explanation, occasionally I can sense high level of uncomfort in him and the answers are ambiguous. So, now I have doubt that "if X, then why A ? " and so on. Should one continue with these kind of questions when you know that the faculty won't be able to answer the questions perfectly or isn't comfortable enough to satisfy your inquisitiveness. I do not doubt his competence at all and respect him very much. But how does a faculty feel in this kind of continuous poking (if it is so) or should one resort to personal interaction so that he may feel more comfortable ?
Does that hold negatively for the student that student is trying to humiliate the faculty ?
Note: Questions are not non-sense but are somewhat basic and supported by logic.
