A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The best ones are thoughts that many people can relate to and they find something funny or interesting in regular stuff.

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. Avoid politics (NEW RULE as of 5 Nov 2024, trying it out)
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct

due to the curvature of the Earth a really long building can't have walls that are both parallel and level. (lemmy.world)

Aparently, I've conflated Level with Plumb, the walls cannot be parallel and plumb. Due to the curve, the center of gravity for the walls would require them to angle in slightly together or not be plumb.

I seem to recall that this has to be accounted for when designing the support towers on particularly long bridges. According to a quick Google search, the most extreme example is the Akashi-Kaikyō bridge in Japan. The support towers are almost 3.5 inches farther apart at the top than they are at the bottom.

Also FYI, the word "level" generally refers to things laying perfectly flat. The word "plumb" refers to thing standing perfectly upright, which is why some jokers in the comments are giving you a hard time, despite what you meant being fairly obvious.
