Is that english...or some secret code?

Professors should try their best to have legible handwriting, especially in any sort of of physics/math-ish class. I ran into a friend of mine, Liz, this afternoon and she was bemoaning the handwriting of one of her engineering professors. We had an amusing conversation.

Liz: "When he write 1/2 sigma pi* It looks like 1 over a drawing of something."

Me: "Like 1 over puppy-dog?"

Liz: "I wonder what the value of 'puppy' is?"

Me: "That would depend on whether it is a pure-bread or a mutt."
