Remember September 2016 2015? That was the month that [Ahmed Mohamed] brought a modified clock to school and was accused of being a terrorist. The event divided people with some feeling like it was ignorance on the part of the school, some felt the school had to be cautious, some felt it was racial profiling, and others thought it was a deliberate provocation from his possibly politically active parents. In the end, [Ahmed] moved to Qatar.

Regardless of the truth behind the affair, this month we’ve seen something that is probably even less ambiguous. The Washington Post reports that a woman told an Air Wisconsin crew that she was too ill to fly. In reality, she was sitting next to a suspicious man and her illness was a ruse to report him to the crew.

Authorities questioned the man. What was his suspicious activity? Was he assembling a bomb? Carrying a weapon? Murmuring plans for destruction into a cell phone? No, he was writing math equations. University of Pennsylvania economics professor [Guido Menzio] was on his way to deliver a speech and was reviewing some differential equations related to his work.

[Menzio] says he was treated well, and the flight was only delayed two hours (which sounds better in a blog post then it does when you are flying). However, this–to me–highlights a very troubling indicator of the general public’s level of education about… well… everything. It is all too easy to imagine any Hackaday reader looking at a schematic or a hex dump or source code could have the same experience.

Some media has tried to tie the event to [Menzio’s] appearance (he’s Italian) but I was frankly surprised that someone would be afraid of an equation. The pen may be mightier than the sword, but a math equation won’t (by itself) down an aircraft. I’ve heard speculation that the woman might have thought the equations were Arabic. First of all, what? And secondly, what if it were? If a person is writing in Arabic on an airplane, that shouldn’t be cause for alarm.

It sounds like the airline (which is owned by American Airlines) and officials acted pretty reasonably if you took the threat as credible. The real problem is that the woman–and apparently, the pilot–either didn’t recognize the writing as equations or somehow feared equations?

Regardless of your personal feelings about the clock incident, you could at least make the argument that the school had a duty to act with caution. If they missed a real bomb, they would be highly criticized for not taking a threat seriously. However, it is hard to imagine how symbols on a piece of paper could be dangerous.

While the mainstream media will continue to focus on what this means for passenger safety and racial profiling, I see it as a barometer of the general public’s perception of science, math, and technology as dark arts.
