Oedipus at Colonus
According to tradition this is Sophocles last play and, with Oedipus and Antigone, completes the Theban trilogy. Oedipus finally comes to terms with his life of triumph, tragedy and disgrace and finds relief in death. He overcomes his tragedy and achieves resolution through the Gods’ acceptance. Contrasts between the relationships between Oedipus with his sons and his daughters underline the picture of a universe that is both arbitrary and inexplicable.

The Mole
This video tackles a concept students often find difficult with demonstrations and analogies. Coverage includes: a look at how substances react in definite proportions, the ignition (remotely) of various mixtures of hydrogen and oxygen, a nuts and bolts analogy to show fixed proportions, the mole and Avagadro’s number and using the mole to calculate chemical reactions.

The Operation of an Economy
North American Version. There are many different economic systems throughout the world, but they all have to address the same basic questions. We investigate these questions, and use the production of bread to show how resources are combined to create goods and services, and the benefits that arise from this process. We also investigate the different sectors in an economy – households, firms, finance, government and foreign – and show how they interact using the circular flow of income. Practical examples illustrate the problems faced when an economy is in a state of extreme disequilibrium.
