I haven't got enough time perspective to know what's useful in the long run. I also just graduated in math.
Fun/easy: a class in ethics and public policy. I find that it's much easier to deal with contemporary debates from the perspective of political philosophy.
Fun/not so easy: Fourier analysis, complex analysis, random processes.
Classes I wish I had taken: any computer science. I had an irrational fear that I'd be blown out of the water by "hacker kids" -- now that I realize there are things I want to do that require more advanced programming, I'll have to self-teach.
Classes that changed how I see the world: intro econ, Fourier analysis
Could you explain how Fourier analysis has changed the way you see the world? I can't imagine how it would change anything.
well, looking at things in terms of a decomposition into frequencies is kind of a universal insight. At least to me. And it inspires different kinds of bases and dictionaries for signal processing. "What's the best basis to expand this in?" is a question I find myself asking about just about everything these days. Getting meaning from observations is, to me, finding a sparse basis representation.
In other words: it kind of only changes how you see the world mathematically, but for me that's a big part of the world.
