• So often mathematics problems yield exact answers. It is a breath of fresh air (pun intended) to work on a problem that does not have an exact answer. Similar problems, that rely on estimates, are known as Fermi problems. The classic Fermi problem, generally attributed to Enrico Fermi, an Italian physicist, is 'How many piano tuners are there in Chicago?' A typical solution to this problem involves multiplying a series of estimates that yield a good approximation of the actual answer.
