Maths writer Alex Bellos was so sick of being asked for his favourite number that he started to ask everyone else the same question. More than 40,000 responses later he had a treasure trove of data.
In a talk that includes mathematics, psychology and the history of science, Alex reveals the curious patterns behind our emotional responses to numbers - what they say about us and what’s important about them.
