I really wish there were something like an "executive" refresher classes on basic maths with a focus on practical applications and modeling. I took Calculus II/III, Linear/Diff EQ and some others in college, but I haven't written a new mathematical model in almost two decades and am rusty.

Try modelling something and see where it goes? The thing with "modelling" is that in my experience it's often justified post-facto so you don't actually learn anything when it comes to modelling as an art. That being said what you are describing is basically a physics textbook, I would say engineering, but they have no soul.

  I have done data modeling for a living and I don't agree that you don't learn anything and that it's used to justify something - you just have to do it rigorously. To that point though, most modeling with any accuracy is done by computer now, and not by hand, which is what my point is. It's impossible to gain an intuition about something if the computer just tells you the answer.

Not sure if it’s precisely what you’re looking for, but I’m currently reading and working through Coding the Matrix, which is linear algebra by way of Python. There are few assumptions and you start coding pretty early on.

  Thanks, I feel like I've run across the book a few times over the years but never was suggested it. I'll check it out

Try Khan Academy, I found it to be a great refresher for things like that.

The YouTube channel 3blue1brown has a good "Essence of calculus" [1] and "Differential equations, a tourist's guide" [2] series that I enjoyed a lot as someone who took calc in college but hasn't used it since.
