You've got a worthwhile project there, but I gather that in sufficiently complex fields (like engineering) there'are a lot of rules and tips because there isn't a complete set of principles.
Can you provide any examples? I have introductory exposure to engineering, but can't readily pinpoint the sort of rules or tips you're referring to.
Page down to Assumptions, Preditions, and Simplifications.
I didn't actually have any examples-- the idea that engineering has methods which aren't firmly based in math or physics was just something I'd heard enough times to have some belief that it was true. The link has some examples.
I'm not sure these are quite the same "rules and tips". There's still a rationale behind model assumptions that an expert could explain, even if that rationale is "this is essentially arbitrary, but in practice we find it works quite well".
