So, I've come across Σ in Maths, and I believe it is a letter in the Greek alphabet.
But has anyone been called it in real life? DH accompanied a school trip to the orchestra yesterday, and the boys declared he was "Sigma". I'm guessing it means something like "cool", but I've never heard it down here in the West Country before.
Anyone? Where is it from?
