[½(My Experiments)]² ± ¾[My Theories] = ???
So it is said that if you know your enemies and know yourself, you will not be imperiled in a hundred battles; if you do not know your enemies but do know yourself, you will win one and lose one; if you do not know your enemies nor yourself, you will be imperiled in every single battle.
One hundred victories in one hundred battles is not the most skillful. Seizing the enemy without fighting is the most skillful.
-Sun Tzu
