Today is Pi Day. While some people might say that Tau is more relevant than Pi, it’s still Pi Day. With that in mind, you may want to wish your friends a happy Pi Day. And while that’s cool, it’s even cooler to wish them a Happy π Day (OK, well, it may or may not be cooler to do this, but it’s definitely geekier!). Unfortunately, we don’t have a π symbol in emoji on iOS. So in order to send that symbol you’ll either have to copy it from the text of this article and paste it in … or you can do what we did in the first place: add the Greek keyboard to your iPhone and type it from there!
