Tomorrow on BBC Two is going to be the repeat of last week's episode of Hannah Fry's The Secret Genius of Modern Life, that I missed. In this series she explores the amazing components and inventions that make up mundane everyday objects. I've just watched the episode about the microwave. Not only is there obvious science in generating the waves, but also using a turntable needed to be invented. Tomorrow will be about headphones. The new episode this week, Thursday, is about lifts.
