Interesting electronics is nonlinear. I recall some college professor
mumbling about solving nonlinear differential equations but it wasn't
encouraging.

Having some gut-level feeling for integration and differentiation and
diff equations and initial conditions and control theory is good, but
Spice can do the actual work.

I taught a course once on dynamic systems. The final assignment was to
write a Basic program to simulate refilling a toilet tank after a
flush. Surprisingly, everybody got it right.
