My physics teacher told me that 37 digits was enough to create a circle the size of the universe.

Back in grade school my twin daughters memorized PI. They were very competitive. One did to 40 something figures, and the other to 50 something. They both got the prize in their class (a slice of pie).

I asked them what the next closest kid had. I think the one class had something in the 20’s, and the other was under 10!

I was thinking that finally there’s some precision in making a circle.

My physics teacher told me that 37 digits was enough to create a circle the size of the universe.

I think that what you teacher actually said was that, given a supposed diameter of the universe of, say, 28 billion light-years, knowing pi to 37 digits was sufficient to calculate the circumference of the universe with an error of less than the size of a typical virus.
