/sci/ - Science & Math

I’m a computer science grad student and I have to pick up a minor. It’s been a while since I’ve done chemistry and physics, but it seems like a good choice, and I’m enjoying Computational Chemistry now. My question for /sci/: How much Chemistry do I need to learn to appreciate quantum chemistry? My linear algebra is fine, I think. But if you were to recommend a book or two, what would you choose? I’ll have time to study over the summer.
