And math works better once you have some sort of intuition about
the things you are talking about, especially if you are doing the
engineering type applied mathematics as opposed to pure math. In my
experience (learning and teaching) presenting different ways of viewing
a given situation or problem is usually helpful. Forcing math (well, if
it's just formulas and calculations as in a typical engineering class
it's not really math anyways) down students' (let alone casual, but
interested, learnes) throats is a lazy way of teaching. Student's as
well as teachers should be able to see past all the mathematical
mumbo-jumbo to the heart of the matter, wether it be voltages and
current or the properties of a symmetric monoidal category. Once the
ideas are clear in the student's head the formal description of those
ideas comes much easier.
