Far out in the uncharted backwaters of the unfashionable end of the Western
Spiral arm of the Galaxy lies a small unregarded yellow sun. Orbiting this
at a distance of roughly ninety-eight million miles is an utterly
insignificant little blue-green planet whose ape-descended life forms are
so amazingly primitive that they still think digital watches are a pretty
neat idea.
-- Douglas Adams, "The Hitchhicker's Guide to the Galaxy"
