This was a plot point in an episode of one of the Law & Order shows, though somehow the writers thought that the calling and receiving phones would have the same ringtone, which was weird.

Programmers work mostly in a discrete world of bits, bounded memory, bounded time, function names that are full words with some hint of the function's job. Mathematicians work in a much 'wilder' world, e.g. where infinite quantities are allowed; they tend to favour shorthand, greek symbols, subscripts, superscripts etc.
