Pi

When you work out Pi, quickly, you can guess it keeps going on and on. But we can’t prove that goes forever cause we can’t play it out. And so, we assume and make an assumption that allows us to do other work. However, we can be stuck in the weeds with data. Sufficient data is sufficient to make our work great. Not perfect. And indeed, if you need your work to be perfect before you present it to the world, well, you’ll never actually ship it then.
