On 17th May, John Adam spoke about his latest book at The RSA (Royal Society for the encouragement of Arts, Manufactures and Commerce). In John’s book, ‘X and the City: Modeling Aspects of Urban Life‘ he discusses mathematical questions such as how you can estimate the number of dental or doctor’s surgeries, petrol stations, restaurants, or cinemas in a city of a given size. How can mathematics be used to maximize traffic flow through tunnels? And what is the likelihood that your city will be hit by an asteroid? One might also be tempted to use John’s methods to work out the probability of an American-dwelling British professor called John Adam coming to a city the size of London to speak at an event that happens to be on John Adam Street. Let us know if you have the answer!
