Circles do not exist

Many logos, drawings and other graphical designs have the following shape in it. What is this shape? If you thought: "Ah-ha! I'm smart and r...

Okay but raster images can't represent circles either, since they're just approximations using squares

- And many "circles" aren't circles either, but 2D torus approximations. The edge of a true circle is made of infinitesimally small points so would be invisible when drawn. And even if you consider a filled circle, how could you be sure you aren't looking at a 1-torus with an infinitessimally small hole? Or an approximation of all the set of all points within a circle?
  
  Clearly, circles are a scam.

  A 1-torus is a circle, you mean an annulus. You do NOT want to make this mistake at a topologist dinner party, trust me.

Well I'd argue vector image can represent a real circle but what's on the screen will never be one.

Also why is this on Lemmy Linux?

- There are analog vector displays.

  Ah yes indeed but there must be some imperfections down the line so not a Real circle, though we are getting closer.

I've been saying this for years! If properties of a shape cannot be expressed with finite precision then how can that shape exist in a universe with clunky restrictions like the planck length?
