You may remember back in September we posted about a mass-participation science experiment, aiming to model the spread of diseases in human populations using a smartphone app. The results of this experiment, presented by the contagiously loveable Hannah Fry, will be presented in a documentary this evening on BBC4. You can also see Hannah chatting about the experiment on this evening’s The One Show.
