Professor Jose Torero delivers the University's 2010 Tam Dalyell Prize lecture. In his lecture, Professor Torero examines the complex nature of fire. He discusses how humans have been fascinated with fire for millions of years. He describes how fire can provide welcome warmth in everyday life but, on a bigger scale, the unpredictability of fire can be terrifying. He contrasted the emotions associated with fire, depending on whether it is under control or not. Recorded on Wednesday 8 December 2010 at the University of Edinburgh's George Square Lecture Theatre.
