It Was Greek To Me, Part 2

(We are learning about sigma notation in math, and our teacher has just explained that sigma (Σ) is the Greek letter ‘S’ and what it means for the notation.)

Student #1: “So, did the ancient Greeks like use sigma to write ‘S’ in their language?”

Teacher: “Yes.”

Student #1: “And all the other math Greek letters too? Like pi and tau and theta and stuff?”

Teacher: “Yes. They still do.”

Student #2: “Wait, what? They still use the Greek alphabet?”

Teacher: “Yes, the modern Greek alphabet is still the same as the ancient one. All these letters are real letters in their alphabet.”

Student #2: “Oh. I thought they used the Cyrillic alphabet. I thought Greek letters were just for math now.”

Student #1: “How do Greek people do math? Don’t they get confused?”
