Fermi problems require you to make a quick estimate
of a quantity that seems difficult or impossible to determine
precisely. They were named after Enrico Ferm, the Italian
physicist who used this problem solving method to predict how
atoms would work long before scientists had the technology
to actually see atoms. Fermi problems emphasize the process
of solving problems over getting the exact answer.
