Fascinating! It had always puzzled me why the tides varied like that,
instead of just following one's longitude. And it probably explains
the Bay of Fundy tides too. Cool.
I love it when the principles we learned from electrical engineering
can be applied to non-electrical things in everyday life. Sometimes I
wonder whether those things would have been understood if it weren't
for EE.

Um, what's so fun about applying impotence??
