> Engineering is the cumbersome real world tweaking and trial-and-error

That's not the only a part engneering.

Engineering is finding a model that can acurately predict the dynamics of a system similar to yours, using that model to make predictions about your specific system and then building and testing that system. This is then done iteratively (i.e trail and error).

Just tweaking a system without a model of how it works is not engineering, it's tinkering.
