I've learned a lot of math that's beyond the scope of what I had in college. I usually find that it works best when it's on the way to something that I'm trying to do or understand. I never really tried to learn math for the sake of math -- I wanted to understand quantum computing algorithms, recommender systems and graph clustering -- and had to fill in the gaps so that the papers in the fields made sense.
