NT_Joke of the Day

[JohnH]

A linguistics professor was lecturing his class on negative polarity, negative concord, & litotes, so he stated:

"In English, a double negative results in a positive. In many other languages, a double negative simply emphasizes the negative intent.  But there is no language known to man in which a double positive produces a negative."

From the back of the room, a student mumbled  "Yeah, right"

@JohnH's sig line, "In theory, practice and theory are identical.  In practice, they are not,"  leads to this response:

I want to live in theory - EVERYTHING works in theory!

@Catherine    Does that include Chaos Theory?

What two concepts occur (and are used mathematically) everywhere in science and engineering, but do not exist in our universe?
