I find this one interesting in the context of math. For example with sin/cos, a lot of people think about it as a phrase "sin is the opposite over hypotenuse", whereas I have this image of sine returning the fraction of how many times does hypotenuse fit into the opposite, which is not word based at all. I can imagine people having vastly different representations of a lot of math concepts.
