YOU MIGHT BE A PHYSICS MAJOR...
if you have no life - and you can PROVE it mathematically.
if you chuckle whenever anyone says "centrifugal force."
if you've actually used every single function on your graphing calculator.
if you frequently whistle the theme song to "MacGyver."
if you think in "math."
if you have a pet named after a scientist.
if you laugh at jokes about mathematicians.
if the Humane society has you arrested because you actually performed the Schrodinger's cat experiment.
if you can translate English into Binary.
if you can't remember what's behind the door in the science building which says "Exit."
if you have to bring a jacket with you, in the middle of summer, because there's a wind-chill factor in the lab.
if you consider ANY non-science course "easy."
if you'll assume that a "horse" is a "sphere" in order to make the math easier.
if when your professor asks you where your homework is, you claim to have accidentally determined its momentum so precisely, that according to Heisenberg it could be anywhere in the universe.
if you understood more than five of these indicators.
if you make a hard copy of this list, and post it on your door.
