Again, analog computers are not computers in a Turing sense or any sense
in which we think of digital computers. In this case, "analog" is not an
opposite of "digital". It means that you design an analog of something
you are attempting to model using for example electricity, water, etc.
Think of them as physical "simulators" rather than computers.
