This episode sees our first ever geologist on the podcast. Tim Chapman is a postdoctoral research fellow at the University of New England. He studies the high energy geological reactions, such as the formation of volcanoes and meteorite impacts, and what influence these have had on our landscape.

As we discuss the cutting edge of geological science, Tim answers such pressing questions as ‘what is a rock?’ We cover hot topics including geology themed sci-fi disaster movies and whether glass can actually flow over time. The take home message is, if you haven’t seen ‘The Core’, go and see ‘The Core’.
