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!

Diff eq basically lists classes of diff eqs for which known recipes can apply.
That "teaching" technique is used, but only in nonmathematics classes.
It's NOT a conspiracy... it's a plot.
