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

-- R. Buckminster Fuller

O divine art of subtlety and secrecy!

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