I'm a physics major & am in my third year. The problem is, I never had a computer science course & when I go to fill out applications for various things, everyone wants to know what my computer science skills are. I'm taking comp. sci. 1 next semester, but from now until the next semester starts, what some good books or references I could read on computer science? I really have no idea where to start, but would like to learn something slightly different from what I'd learn in the comp. sci. I course.
