Truth is stranger than fiction. The Washington Post reports:
she’d seen had been her seatmate’s cryptic notes, scrawled in a script she didn’t recognize. Maybe it was code, or some foreign lettering, possibly the details of a plot to destroy the dozens of innocent lives aboard American Airlines Flight 3950. She may have felt it her duty to alert the authorities just to be safe. The curly-haired man was, the agent informed him politely, suspected of terrorism.
The curly-haired man laughed.
He laughed because those scribbles weren’t Arabic, or another foreign language, or even some special secret terrorist code. They were math.
Yes, math. A differential equation, to be exact. Had the crew or security members perhaps quickly googled this good-natured, bespectacled passenger before waylaying everyone for several hours, they might have learned that he — Guido Menzio — is a young but decorated Ivy League economist. And that he’s best known for his relatively technical work on search theory, which helped earn him a tenured associate professorship at the University of Pennsylvania as well as stints at Princeton and Stanford’s Hoover Institution.
On a lighter note, the Economist gives “Ten ways to tell you might be sitting next to an economist.”
