Look at a coffee cup.
- TeMPOraL 3y agoHow can I distinguish between errors of perception, errors in manufacturing, and errors of perception of the designer who eyeballed circles on a computer screen with non-square pixels?
- InitialLastName 3y agoWith a coffee cup, you should be able to take a micrometer (or a piece of string) and verify roundness of the base object to whatever arbitrary precision your heart desires (and your reality will allow).
- TeMPOraL 3y agoI don't think I've ever seen a coffee cup that would let me do that. As I said earlier, I don't really trust their roundness, and that's on top of them usually being made of some kind of ceramic and thus having grain. (Maybe a cheap, single-use plastic cup would be smooth enough and stiff enough and round enough, given the production process.)
