Meme of two women fighting while a man smokes from a pipe in the background.
The women fighting are labeled “mathematicians defining pi” and “engineers just using 3 because it’s within tolerance”
The man smoking is labeled “astrophysicists” and the pipe is labeled “pi = 1”

38 digits of pi can get the circumference of the visible universe to within a single hydrogen atom.
10 digits gets the diameter of the earth to within an inch.

Put another way, 10 digits means that your error will be caused by your imprecise model of the Earth’s shape, rather than imprecision in the value of pi.

out of curiosity… does that first fact account for the continued expansion of the universe?

It works at the current 93 billion light years of observable universe (46ish in every direction)

And just two digits introduces less error than your terrible model

Wow, what do you have against models? I mean, I know that the trope is that they aren’t very smart, but the same trope applies to firemen, so why pick on models?
