I'm a theoretical physics grad student and a night school maths teacher, I have never heard this distinction. People in academia around me call them round and square brackets.

    It's a US vs UK (and probably others) distinction. The ( ) are almost never called brackets in the US, unless it's a regional thing I'm not aware of. Also the [ ] didn't get used in any math classes I was in the US up through calculus except for matrices.
