Summary: Philip Dodd talks to the writer Jonah Lehrer whose new book sets out to unravel creativity and understand the imagination. Thirty years ago the film Koyaanisqatsi was released and Jon Adams, a Radio 3 New Generation Thinker, argues that it's lasting legacy is the effect it has had on the advertising industry. Philip and guests also take a look at the World Shakespeare Festival, in particular the Globe Theatre which is staging all of Shakespeare's 37 plays in 37 different languages. And, as the Science Museum puts on display a Ripley Scroll recently discovered in its archives Philip explores the resurgence of alchemy's reputation with the historians Jennifer Rampling and Peter Forshaw.
