Ah Analog computers, this topic has come up before on the list, I wrote
this in 1995:
Welcome to the exciting world of analog computing. Thanks to the new Heath
Home Study Course you can build your very own analog computer in the
privacy of your own home. Make big bucks! Amaze your friends! Be a hit at
parties! This is a true analog computer, no wimpy pseudo analog stuff here,
this baby can handle infinity.
Before we begin construction there are a few helpful hints I'd like to pass
along. Always keep your workplace neat and clean. Make sure your
computer is cold, as it will not operate at any finite temperature above
absolute zero. Use only analog substances and processes, never use digital
things like matter, energy, spin,
or electrical charge when you build your analog computer.
Now that we
got those minor points out of the way we can start to manufacture your

any infinitely accurate measuring stick you have handy and ..
Back then the great
was on the list and he too had something to to say about analog
computers and the people who love them :
*"people who happily assume that analog computers bring some mysterious
sort of infinite precision that cannot be simulated by a mere 64-bit
computer working with double precision floating point. I used to
use analog computers, [...] If you were real careful, even at Room
Temperature, you could sometimes get close to 10-bit performance for brief

There are an infinite number,
infinite number, of maps that can be drawn on a flat square, but only 4
colors are needed to keep all the countries on the map separate. This was
proven by a computer
to this day nobody can prove it without a computer.
