You may be an engineer
- If you know vector calculus but you can't remember how to do long division.
- If you chuckle whenever anyone says "centrifugal force."
- If you've actually used every single function on your graphing calculator.
- If you have to bring a jacket with you, in the middle of summer, because there's a wind-chill factor in the lab [and you have calculated exactly what it is].
- If you hesitate to look at something because you don't want to break down its wave function.
- If the Humane society has you arrested because you actually performed the Schroedinger Wave experiment ... with a cat.
- If, when your professor asks you where your homework is, you have the temerity claim to have accidentally determined its momentum so precisely, that according to Heisenberg it could be anywhere in the universe.
