This article about the current decades-long work to recalibrate the notion of "height" in US geological surveys and so forth is fascinating and reminds me so much of like... in a video game engine when you get too far away from the origin and start losing precision in your floating point numbers and suddenly your physics starts to glitch

@darius This from the article: "Some Coloradans worry that a few of their mountain peaks will fall below a bragging-rights threshold under the new height system" reminds me of this movie starring Hugh Grant.
