Synchronicity: These examples of stupid both involve Italians. In one case, a very smart Italian got stupidated by some “see something, say something” moron. In the second case, a very creative but perhaps not-so-smart Roman architect got outsmarted and doesn’t like it.
1. Math + dark hair + airplane equals terrorism
2. Carl-Bear Bussjaeger would like to remind that spluttering Roman architect of the Streisand effect.

Proof that architects today use cad, nothing has weight or external effects.
Venturella must have been drunk when he thought that one up.
(He’s an excellent example, BTW, of my belief that the human mind is both the best and the worst that evolution has to offer.)
That Something 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.
Even if you discount the “foreign” math angle I seriously doubt any “terrorist” ever would be sitting, waiting to taxi, and writing “I’m going to hijack this plane” anywhere someone could see. Once he’s aboard, it’s a bit late to be making notes.
Now I have to forward the link to my son-in-law, who fits the economist’s description. Although he would be working out a recipe, not a math equation.
Venturella’s global cooling skyscraper may be unbuildable, but it’s still a hugely better idea than taxing CO2 emissions.
They’ll need the CO2 tax revenues just to fund the R&D for the unobtainium construction materials.
Long before the “terrorism” thing, I got questioned by the authorite’ when they spotted cryptic runes on a sheet of paper I was using. It took a while, what with their narrow mindset, for me to explain that these were logic diagrams and schematics for a computer I was designing. No, you can’t fix stupid. But you can enjoy the entertainment value.
