Betting on science, The Simpsons and how maths keeps aircraft apart — More or Less returns to BBC Radio 4 from 4.30pm on Mondays.

Among the stories featured in the latest series presented by Tim Harford will be the tax-free phenomenon of spread betting, how some scientists are making money by betting on their own theories being proven correct, and how air traffic scheduling relies on mathematics to function and bring aircraft safely into land.

Later in the series will be a round-table discussion featuring the Rt Hon Charles Clarke MP, Vince Cable MP and Fraser Nelson, political editor of The Spectator, about how numbers influence politics and policies and how they are often the most important part of the story. There will also be an exclusive interview with Al Jean, head writer and executive producer of The Simpsons and Harvard maths graduate, on his love of numbers and how to constantly get good numeracy jokes into the world's longest running sitcom.
