Stay media-literate with John Davies's weekly radio and television round-up. (All times pm unless stated.)

Pick of the week

Geology gets the blockbuster treatment in BBC2's ambitious new series Earth Story (Sunday 8.00). Aubrey Manning, emeritus professor of natural history at Edinburgh and an animal behaviour specialist, is the front man. Other experts, such as Oxford's Stephen Moorbath, Dan McKenzie of Cambridge and oceanographer Rachel Mills do the explaining in the opening episode, which visits South Africa, Greenland and Lyme Regis to answer the question "How old is the earth?" A companion series, The Essential Guide to Rocks (Monday 8.00 BBC2), focuses on Britain's geology, starting with the South Downs.
