cornjchob asks: "I've been a Slashdot reader for quite sometime now, and I've seen alot of Physics articles posted. I've got a good understanding of alot of it, but that doesn't mean there's no room to improve. So what's some good reading material for Physics that will give you a good, solid foundation if you've missed something, and then give you some additional stuff? What about online articles or PDF's for us cheap folk? Quantum Mechanics is another subject area that--judging by alot of posts underneath the articles, at least--many of us could use some brushing up on. Any suggestions for books/articles/PDF's on that? Suggestions on anything pertinent to any of those would be great."
