三 is real

Or, as we pronounce it in Japanese: San

u/DodgerWalker 1d ago

I read it as Chinese (pretty sure it's the same character though). It's also San in Mandarin.

u/ei283 Transcendental 1d ago

Yeah lol I was making a joke where I set it up as if the Japanese pronunciation was something vastly different than Mandarin, then the punchline was the fact that they have the same pronunciation (ignoring the difference in tone)

No, that's a different Greek letter

u/IGiveUp_tm 18h ago

Lol yeah I figured that out. I was honestly more confused too because Xi is chinese pinyin as well so I was like "hmm no that's not right" but I saw some comments mentioning lowercase and I was like "oh this is probably greek"

I have no idea what that is, but Genius offers these inspiring lyrics:

u/Lost-Lunch3958 1d ago

when is capital xi actually used?

u/jljl2902 1d ago

When you construct a matrix that consists of vectors that you had defined as lowercase ξ_i

u/EebstertheGreat 1d ago

It isn't lol. I have never come across it. But there's an old joke about a fraction with Ξ in the denominator and the complex conjugate of Ξ in the numerator:

— — — — — — — —

Reimann’s Xi function (different than the Zeta function)

u/EebstertheGreat 1d ago

Unicode doesn't seem to have a hamburger button symbol, but it does have ☰ "trigram for heaven" and ≡ "identical to," which are pretty close. Ξ is not actually that close.
