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.

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. 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.
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct-----

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

If you don't squint, it looks like a table. Maybe whoever chose it hadn't had lunch yet.

What is this Cunningham's law?

Pi is not half the circumference. It's how many times the diameter fits into the circumference.

It is half of the circumference, multiplied by the radius, of course.

like in this image I found online

Now you're just being silly.

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
