Paul Krugman sometimes starts with a graph and then goes to learn the math

I am glad to hear this from someone so well-known, because I’ve leaned in this direction myself:

My own mathematical intuition, and a lot of my economic intuition in general, is visual: I tend to start with a picture, then work out both the math and the verbal argument to make sense of that picture. (Sometimes I have to learn the math, as I did on target zones; the picture points me to the math I need.) I know that’s not true for everyone, but it’s true for a fair number of students, who should be given the chance to learn things that way.

Figure out what kind of dynamics you want to study, then go learn the math.

At a personal level, for personal interests, I would like to learn more about how matrixes interact with sparse matrixes.
