"Why models?"

I love the book "Orbiting the Giant Hairball" by Gordon MacKenzie. In fact, I asked the publisher for permission to publish a small section of the book. I was allowed to publish the section for a few months for a fee. But, I didn't. Seemed silly to pay to be able to quote Gordon for a limited time.

Anyway - here you can find one great text from the book: "Why models?"
