I like to think all this knowledge eventually has some payoff. It's just a matter of being imaginative and determined enough to figure out how.

Ah, the memories. The horrible memories of diff eq. :)

Ever more to play around with here. Don't things usually progress from new discoveries and methods that are clunky/unnatural to ones that seem less intuitive at first, but easier and, in the end, more natural/intuitive? Maybe I'm overgeneralizing. There's also a difference between what's taught to undergrads at one time versus later because, I think, "newer" ideas just take time to work their way from the bleeding edge to the textbook. At least, this is my impression, FWIW.
