I'm reminded of a tale a friend of mine told me.  After graduating from
college and ROTC he chose to go to the Army electronics school.  As a
pretest he was asked what are the three most important laws of
electronics.  Well he thought about that a while and chose j=sigma* rho,
and Kirchoffs laws.  As it happened what they expected was
V=IR, I = V/R and R = V/I

scary
