Mandelbrot set calculation is a curious intersection of math and computer science. I went down that rabbit hole once :)

Naive implementation is easy, but there are many ways to improve performance.

Strange thing to say since CS is a sub-field of math.

[Etheryte]

I wouldn't really say that's a universally held notion, especially in the modern world. Historically, yes, but these days it stands more on its own. In similar vein, you could say biology is a subfield of physics, but most people don't think of them that way.

To a librarian, Computer Science and Library Science are just different aspects of information systems, which are (a librarian need hardly tell HN) humanity's highest calling, thus justifying their shared Dewey classification of 0.

It's not really philosophically, though. As a pure mathematician, I would not consider CS a subfield of math. The spirit of math is really studying abstract axiomatic systems, and while CS in theory is sort of like that, in actual practice, CS is too tied and focused on the actual instantiation of computers to really have the spirit of math.

I think that statement held true before widespread availability of computing; when most computer science was really theoretical. I once skimmed a few chapters of a graduate-level textbook on Category Theory and realized that it was the foundation of object-oriented programming.

The biggest issue is that a lot of "Computer Science" is really applied software engineering; much like confusing physics and mechanical engineering.

Or, a different way to say it: Most students studying "Computer Science" really should be studying "Software Engineering."

More practically, I have a degree in Computer Science. When I was in school, it was clear that most of my professors couldn't program their way out of a paper bag, nor did they understand how to structure a large software program. It was the blind leading the blind.

All fields are subfields of polymathy.

[ks2048]

Of course these terms aren’t well-defined, but some (me) would say both math and CS are subfields of “formal systems” (but “formal systems” could be named CS, which would put it at the top of the hierarchy)

Software engineering has as much to do with sociology as it does with math.

Systems software has to deal with a lot of physics and engineering stuff (speed of light, power, heat, mean time to component failure, etc, etc.)

…and I thought math branched off from computing science sometime in the 19th century. Before that, what was called „math“ was mostly algorithms to compute stuff.
