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.
