Texts for Autodidacts?
RestiffBard asks: "I'm in a bit of a learning slump and was wondering what books or websites Slashdot readers would recommend for learning anything. I'm looking more for general starter texts on physics, math, chemistry, electronics, etc. I'm not too interested in computer texts as I have that mostly down now. I'm more interested in the sciences that I've neglected in the last few years."

Useful for older texts, so no cutting-edge genetics or nanotech here, but this collection would round off your education in general, especially the classics if you're that way inclined.
