This is great! I actually just bought a slide rule a few weeks ago (a Pickett N902-ES), and I've been working through the original booklet. One reason I bought it was to get a different perspective on calculation, since I never used a slide rule in school. Case in point: I do a lot of cooking, and this use case never occurred to me.

If your goal is a different perspective on calculation, I warmly recommend learning mental maths with logarithms too. Not only does it complement slide rule practise, but it also gives you a linear/additive understanding of multiplication/powers which is useful.

I don't understand complex numbers and time--frequency domain translations but I suspect a log understanding feels similar to those.
