Someone has put a series of the brilliant Mark Steel Lectures online which are an informative and hilarious romp through some of the most important historical figures in history.
They were created by the BBC for the Open University to both educate and enthuse people about history and contain wry insights into both the work and lives of the people featured.
The programmes on Freud, Aristotle and Descartes are likely to be of most interest to Mind Hacks readers, although the whole of this series has some fantastic gems.
