>>13845063I actually understand your question OP. No, no you don't. In fact the majority of the work you do in introductory CS courses is pretty useless for computational work.
The algorithms that you build in these fields are much different than the algorithms built in CS and they are not as autistic about the fundamentals. Generally speaking, computational work is focused on well-posed, well-conditioned problems and stable convergent solutions. Most of these solutions pop straight out of the mathematics of discretizing problems.
Saying that, these CS algorithms are fundamental and you get a very strong understanding of computer logic from studying them. They really do teach you the limitations so they aren't even if they are annoying.
You should check to see if your university offers something like a computational mathematics, scientific computing, or some other degree along those lines. That's what you're looking for.
