Maybe this is why pi was chosen for half of the circumference of a circle.

I can level up with more sources (stanford, wiki).

The circumference is 2pi x radius, which obviously means half the circumference is pi x radius.

Edit: formatting. Asterisk results in italics

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. A showerthought should offer a unique perspective on an ordinary part of life.

The entire showerthought must be in the title
Avoid politics
1. NEW RULE as of 5 Nov 2024, trying it out
2. Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
3. Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
