Models

Models are brilliant; they lasso the abstract and wrestle it to the ground so that everyone, not just the academic cowboys and cowgirls, can have a piece. It's like killing a wild bear, stuffing it, and standing it in the family room for guests to wonder at and talk about. Or, maybe it's more like drawing a picture of a wild bear using numbers and new terms, photocopying it, and putting it in your syllabus for everyone to wonder at, and talk about.
