How much should a mathematician confine themselves to a particular area if they are to be successful? My main discipline is PDE however, I have a heart for computer science too. I am wondering if I should work to get my knowledge in the ladder area up or continue what I am doing. My plan is to do research in PDE as a career, but is there possibly room for Computer Science in my research?
I guess, if I were to do both, the question boils down to if there exists such an occupation in which I could do both. Any other way, coding and computer science would be mere hobbies which I am fine with however, less satisfies with.
This question can be generalized to the cases of others too, though: What is more important, getting insights in your main discipline, or strengthening your knowledge in weaker, less familiar areas of mathematics that may be somewhat unaffiliated with what you already know?
