Radiator construction

LOL oh man you got that right, I'm an ME and trying to take Physics 2 (E&M) and Circuits was like trying to learn Chinese... Thermo is my favorite subject but when it comes to electricity none of it makes sense to me.

I thought I was good at heat transfer (actually a separate course from Thermodynamics) until I took this past grad-level class, holy crap talk about a reality check.
And not to betray my age but I was also required to sort out a Wheatstone Bridge in one of my core classes. Baffled me then and frankly I have never used it in thirty plus years in the field. Instructor was adamant that we understand it. He was maybe 90! Hah! I would love to throw a 4-20MA loop on him today! All that for a Mechanical guy! Never understood some of the rationale behind curriculum. I ended up helping establish curriculum for Mechatronix classes at a couple universities. I can assure you there was no Wheatstone bridges included!
