Stand-up mathematician Matt Parker, experiments maestro Steve Mould and geek songstress Helen Arney take a single word or phrase as a jumping off point to investigate things that you wouldn’t believe could be interesting, but turn out to be utterly fascinating when you get down to the nitty and / or gritty. Also featuring new science songs from Helen!
