Structural Engineering is the Art of molding materials we do not wholly understand into shapes we cannot precisely analyze, so as to withstand forces we cannot really assess, in such a way that the community at large has no reason to suspect the extent of our ignorance.
Down here in Wilmington they once put up a sign saying "Delware Ave", but then took it down within a couple days to fix it. I have a sticker of the misspelling on my laptop.
I drove past there on Friday, saw that sign, and totally did not notice the reversed letters. In my defense, it was about 6:30am and I was operating on 2 hours of sleep. Also I was too busy marveling that very soon the Cottman on-ramp will actually be on Cottman, instead of Princeton or Longshore. Wasn't sure if I'd live to see that.
I have it in my head that PennDOT intentionally fucks up Philadelphia just for the fun of it. The number of poorly placed signs, misspelled signs, missing Lane markers, and just random shit that PennDOT pulls on its roads around here is too high to be anything other than purposeful.
I think this is a good learning moment for people in favor of progressive taxes or more taxes in general......this is who you want to give more money to
