This just in from the front lines of the War on the Unusual:
University of Pennsylvania economics professor Guido Menzio was solving a set of differential equations on a plane departing the Philadelphia airport when the woman next to him surreptitiously passed a note to a flight attendant telling them she thought he was a terrorist because of the strange things he was writing on a pad of paper. The plane returned to the gate where he was questioned. At least this time the pilot had enough sense not to kick him off the flight.
Remember folks, if you see something say something!

I have a math degree, of course I took DiffEq. And yes, I remember well the massive appendices full of equivalencies and solved forms. But if that's all you got out of the class, then it was a waste of your time - those were just the "cheat sheets" to save you untold hours of tedious grinding.
