What I meant was that in the title of the book they
use "digital computer"
and I wonder if there was ever a book describing a mechanical "analog
computer" - and what they might even look like.
half a century ago, my cousin showed me some plexiglas blocks with odd
shaped holes through them, and said that they were from an experimental
analog computer. I guess that you could figure out fluid behavior by
making analogies to electronics - amount of flow is kinda like current,
amount of head or pressure is kinda like voltage, restrictions are kinda
like resistance, one way valves are diodes, . . .
