Can anyone recommend any introductory material on real-world examples of differential equations? I don't mean the first-year undergrad textbook stuff with differential equations for population growth and chemical reactions and mechanics that can be solved via separation of variables etc. I mean descriptions of models used in science and engineering that result in needing to use the fancy solvers that this thread is discussing.

Electronics is all about differential equations.

All the way down to transistors and other basic elements
