Everything you've learned in school as "obvious" becomes
less and less obvious as you begin to study the universe.

For example, there are no solids in the universe. There's
not even a suggestion of a solid. There are no absolute
continuums. There are no surfaces. There are no straight lines

Devastating Device
This nasty little ten dollar bug could
totally devastate your business
and your life. Are you prepared to
have that happen?

Even in friendly territory a fortified camp should be set up;
a general should never have to say 'I did not expect it.'

-- The Emperor Maurice,
