A while back, Lukeprog set up an article to list the best textbooks in every subject. It currently contains a fairly large list of books in a variety of subjects.
I just got an e-mail from Amazon advertising "Up to 90% off textbooks" and I thought "This seems like a good opportunity to check out a bunch of cheap, good textbooks in subjects I want to learn about!"
When I went over to Luke's post, I discovered recommendations for philosophy, psychology, all sorts of math, but almost none in basic science.
I assume that someone here must have read one or a few basic textbooks on physics, biology, and chemistry. If so, what were they? How were they? Would I be better off just trying to take a basic lecture course in the subject, or going through Khan Academy?
I'm still keeping that post up to date, by the way, as long as people add recommendations (to the original post) that follow the stated rules.
