I have been taking a whole bunch of online courses for a couple of months now, some of which are more challenging to me than others. I don't watch the lectures because they take too long, I usually just stop the video and click on the subtitles to read the slides. Even then I sometimes fail to pick up what I am looking for. If there are concise notes or formula sheets I will refer to those instead (online textbooks are hard to use and don't get to the point) but the lecture thing makes me wonder, what are lectures for, and why are they more helpful to people than books or notes or formula sheets alone? One reason I think many people would give is that the professors are supposed to describe to you the intuition of the problem. What does this mean? Why can't they just give me the freaking equation? If I have the equation and a few definitions for what each part of it stands for I will usually be able to figure out how to use it. I just think about it for a while and imagine it in my head to get an idea of how to use it. See, I usually figure out my own way of figuring out problems, and I often get them right which always surprises me. Is that unusual that I can do that? Am I delusional for thinking I can pick up the 'intuition' this easily? Is it normal for people to require to hear a professor say it in order to understand it, or need to work with other people to understand it? If I hear it in spoken words it doesn't register or encode into memory correctly for me, I think it may be because I am autistic but I imagine there are a lot of autistic physics people and they don't seem to have the problems I do in a classroom setting with having to hear people talking in order to receive a license to use certain intellectual faculties? If I don't understand material well using lectures and especially suffer troubles if I hear it and it goes into my audio memory does that make me severely mentally disabled and therefore not cut out for a career in academia???
