| Sumario: | Some questions that arise in everyday situations, such as 'How long will it take to get to the airport?' can be solved by making a quick estimate. In other cases, we can ask ourselves about situations that we have never considered before, where we are interested in obtaining a first rough answer. This would be the case if we ask how many planes are flying all over the world at a specific time are, or the amount of CO2 emissions we could avoid in a city if gasoline-powered cars were replaced by electric ones. These two questions are examples of Fermi problems. They owe their name to Enrico Fermi, who used this particular type of problems both in his scientific work and as a university teacher. Fermi problems, being smaller, more well-defined and delimited contextualised problems and not real-world problems in all their complexity, have been considered to be miniature-modeling problems (Robinson, 2008). |
