I don't understand why anyone would memorize pi to more than 3 digits, other than by accident (such as the sibling, who just saw it on a campus wall countless times).
Those 3 digits are good for ~0.05% error, plenty good enough for any mental calculation you might want to do. In any other context you would have pi trivially available as a constant anyway, right?
- Sharlin 5y agoMaybe "go-to" is the wrong word. It's just that those are the digits I remember off the top of my head. I don't remember whether I made an actual effort to memorize them as a kid, it's been over twenty years. But they stuck and are not easy to forget now.
- patrec 5y agoCool, makes sense, but I'd put that under the accidentally memorized camp :)
