I'm getting ready to register for classes for the fall. To make a long story short, I might have to take another math class to satisfy a degree requirement, rather than a computer science class. I'm taking Linear Algebra right now. I enjoy it, and it seems to have a lot of practical applications. Next semester, I have two options: differential equations or number theory. Which do you think would be a better choice for my career, in terms of building a knowledge base? I'd like to work for a company that does a lot of scientific research. I don't mind writing code for business or anything like that, but I'm really interested in science. Differential equations would strike me as more useful for science. Number theory seems more like pure mathematics. On the other hand, that might help me understand a lot of computer science concepts better. What's your opinion? I can add more information about these courses if you want it.
