.Plus when you get into upper-division stuff, PF becomes fairly worthless if you have any respect for the people who help out here. PF has a lot of people that can help out with lower-division stuff and its fairly easy for them because they're normally short and quick.
I've really found that the opposite is the case. If you have a question on how to calculate Ricci tensors in general relativity, just the fact that you are asking the question means that you have a lot of math background so that I can just point you to a web page or a review article, and you can figure the rest out.
The hard part is teaching someone that doesn't know algebra but wants to learn. *That* takes a huge amount of time, because they don't know what questions to ask, and you have to sit down with them, watch them struggle through the problem, and then try to figure out what they need to know.
Also it's harder to teach someone that is in lower division. If someone asks me about Ricci tensors, and I'm a total jerk about it, it's not going to make much difference, but it does make a huge difference if someone asks me a basic algebra question.
The other thing is that sometimes what you just need is moral support. I have a Ph.D. in astrophysics, I have an undergraduate degree from MIT, and I work on Wall Street as a researcher. I happen to think what the original poster is trying to do is wonderful, and I'll do what I can to help him. Now, all you need to know is that there is one person out there that believes in you, and that gives you "permission" to ignore anyone out there that doesn't.
i don't think many of them will spend the time necessary to replace the time a professor would spend with you to help you out.
For upper division stuff it's easy. I just point you to the web page where someone has worked it out. The thing that I don't have time for is lower division stuff, since to explain basic Newtonian mechanics to someone that doesn't have that background is hard.
Of course, this comes from someone who is in a rather small department with professors that are amazingly more dedicated to their students then what you'd expect at say, a UC campus's political science department. It's a consequence of the smaller department and my university being a teaching university as opposed to research.
Oh yes. The thing about professors at some of the major universities is that they get hired for research, and are just horribly bad at teaching.
