I have a situation, I was home schooled and now I don't know any math at all. It's so frustrating. How do I self-learn all of HS math?

If the Universe's expansion is constantly accelerating, how come gravity keeps things together just the way they are at least on a local cluster level? I mean, the distance between the Moon and the Earth is constantly getting larger, is it not? What am I missing?

I just discovered that the professor for my college algebra class has a heavy Ukranian accent. I don't understand accents well, so I went to see what other offerings there are, and the only other opening that I can work into my schedule is a professor with a Chinese accent.

Why do people who major in pure science look down on engineers, even engineers in their respective field (chemical engineers, for example)? Is this just a /sci/ thing? Are they jelly of the paycheck?
