I often had difficulty figuring out why certain (unnecessary) assumptions were made, and I came to the conclusion that they were made to make the class more manageable for the least capable students.
I found this when I TAed physics for engineers, which was sad. The professors (through experience, no doubt) didn’t trust students to propagate errors by adding in quadrature, and so they were told to just add the standard deviations together. I was scared by the idea of an engineer who couldn’t sum errors that way.
Interesting to hear your experience as a TA validates mine as a student. That’s a good example of what I mean by an unnecessary assumption or simplification that was done purely to make the class more manageable for some students.
A not-insignificant portion of engineers don’t know much anything about physics or math and want nothing to do with either. This is very scary, because these people tend to blindly follow standard engineering practice (which is not necessarily correct) or worse, make up something that is very wrong. A friend of mine told me they went to a job fair and heard a recruiter for an engineering company brag that you won’t have to do any more calculus if you worked for them.
As far as I can tell, a significant fraction of the people in every major don’t really understand it, don’t care very much, and are continually half-assing everything. The problem with just flunking these guys is that they can still be valuable to employers, and their tuition money is nice to have.
