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 Fermi, 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.
