* What Does a Legitimate Bug Sweep Cost?

Therefore, I say:
Know your oppositions capabilities and know your own equipment;
in a thousand bug sweeps, you will never miss a bug.

When you are ignorant of your oppositions capabilities but know your own equipment,
your chances of finding the bug are equal.

If ignorant both of oppositions capabilities and of your own equipment,
you are sure to never finding the bug, and the opponents spies will succeed.


- James M. Atkinson, c. 1986

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!
Through you we learn to be invisible, through you inaudible;
