I am experimenting with the Coursera/Caltech course Principles of Economics for Scientists, taught by Antonio Rangel. He promises to show that economics is a science with testable models and experiments, while promising to cover the essentials of what is usually a one year course in one term by using fewer words and more calculus. Econ for geeks.
