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.

      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.
