That's an interesting connection to point out, thank you. I have no real understanding or even awareness of analog computing. I recall leafing through an old textbook on chemical engineering earlier this year (as I was looking for practical applications of graph theory), and read a little about the use of analog computing to solve ODEs, and being pretty surprised. This might be an interesting read: "Handbook of Analog Computation" [1].
