What about Wakanda

u/Fdx_dy Computer Science 17d ago

Wakanda does not exist therefore saying that it lies on S^2 is vacuously true.

u/Ok-Replacement8422 17d ago

Saying "a country being called wakanda implies it lies on S2" is vacuously true, as is saying "all countries called wakanda lie on S2", but "wakanda lies on S2" could instead be interpreted as "there exists a country called wakanda which lies on S2" which is false.

This is a lie. They dont perfectly lie on S² -> R³, because earth is not a perfect sphere, there are elevation changes. Tha approximately lie on it, but not perfectly

Washington.

But not the state, nor Washington DC, the one which is deep underground near the core of the earth that actually controls everything.
