I disagree that mentally separating math, physics, and computer science is a good thing. I think a good scientific programmer should understand the science on its own, and then figure out how to model/approximate the science to do something useful on a computer. For instance, if you want to implement Reed-Solomon codes efficiently, you'll realize that understanding the algebra required to understand the code is more or less an orthogonal skill to designing an efficient encoders and decoders. As a personal anecdote, I had much better luck learning about waves and quantum mechanics after I knew about differential equations, orthogonal decompositions, and a fair amount of linear algebra than I did before I knew this math, even though the physics classes included all of the necessary math. I attribute this better understanding to have a cleaner mental map, because I knew which statements were true because of some sort of physical fact, and which statements were just mathematical results. In line with the generally smiled upon principle of decomposing problems, I think its particularly critical that the scientific programmer can decompose these interdisciplinary problems. A scientific programmer should understand the science (at least mostly), understand the hardware, and figure out how to efficiently and cleanly map the scientific problem to something that to be solved by a program.
