Models & Theories:

"On well-trodden ground we build theories. On the half-explored frontiers we build models."

Freeman Dyson

-----

"As a scientist I make a sharp distinction between models and theories. A theory is a construction, built out of logic and mathematics, that is supposed to describe the actual universe that we live in. A model is a construction that describes a much simpler universe, including some features of the actual universe and neglecting others."
