I’ve always pronounced the Greek letter pi as “pie”. That’s how my math teachers taught me to say it. Today, I learned it’s pronounced “pee”. I don’t know why. It just is.
Now I’ve got to figure out why it’s different (for my own curiosity’s sake). Is it because the nation where the math concept originated pronounced the Greek letter that way? Is it because high schoolers and middle schoolers can’t handle a concept pronounced “pee”?
Ahh, the big life questions.
