Another great entry from xkcd. I remember a real version of this science scale presented to me in college, but the professor labeled the sciences on the left as weak sciences and the ones on the right as strong sciences. It seems that Engineering and Computer Science have been left off – on purpose I suppose, since they would be pretty close to Mathematics and thus ruin the joke.
