Then why would they need to learn it?
I should have said, “It is unlikely that a chip designer or mechanical engineer COULD learn the required math on the job.”
I have met many self-taught computer programmers whom are competent for many tasks but lack essential math background and thus fall flat when presented with a project requiring such.
My grandfather was a mechanical engineer in the Forties and I have his engineering texts and slide rule. He did not learn the mathematics on the job—he learned it at university.
