Our Brainy Lecture looks at the wiggly jiggly world of superstring theory and we ask whether a whole generation of physicist have just wasted their lives. We turn our attentions and saucepans to a Cider Beurre Blanc. This week’s song under microscope considers the enduring charm of Polly Put The Kettle on and examine what exactly has kept this infusion centric ditty in the charts for the last two hundred years. That gets us thinking about the whole canon of gruesome english language nursery rhymes.  In literally the last section we investigate how words enter the english language. We also look at the body image issues and the glorification of binge eating  in the blockbuster book by Eric Carl, The Very Hungry Caterpillar.
