Guido Menzio an economist at the University of Pennsylvania–author of Block Recursive Equilibria for Stochastic Models of Search on the Job among other papers–was pulled from a plane because…algebra is suspicious. From FB:
Flight from Philly to Syracuse goes out on the tarmac, ready to take off. The passenger sitting next to me calls the stewardess, passes her a note. The stewardess comes back asks her if she is comfortable taking off, or she is too sick. We wait more. We go back to the gate. The passenger exits. We wait more. The pilot comes to me and asks me out of the plane. There I am met by some FBI looking man-in-black. They ask me about my neighbor. I tell them I noticed nothing strange. They tell me she thought I was a terrorist because I was writing strange things on a pad of paper. I laugh. I bring them back to the plane. I showed them my math.
It’s a bit funny. It’s a bit worrisome. The lady just looked at me, looked at my writing of mysterious formulae, and concluded I was up to no good. Because of that an entire flight was delayed by 1.5 hours.
Trump’s America is already here. It’s not yet in power though. Personally, I will fight back.
Algebra, of course, does have Arabic origins plus math is used to make bombs.
Addendum: here is the Washington Post on the story.
