I think that you misread my post. I said it would not AUTOMATICALLY make them the most knowledgeable scientist. Obviously a new breakthrough such as the cure for cancer or discovery of Relativity by Einstein would likely place a scientist near the top in knowledge. Qui-Gon made a great discovery. Is it at the level of a cure for cancer? That is debatable. I do not believe that his discovery means he has more knowledge over a Jedi who have been studying the Force for a nearly a millennium.
