Abstract: The muon has been a source of interesting physical phenomena ever since itsdiscovery which prompted Nobel Laureate Isadore Rabi to exclaim, ``Who orderedthat?'' The anomalous magnet moments (g-2) of the (first) the electron and (now) the muon have provided evidence of the spectacular success of quantum field theory. However, for about twenty years there had been about a three standard deviation tension between the experimental measurement of the muon g-2 and the Standard Model calculation of its value. In April, 2021, the Fermilab g-2 experiment announced its initial result. Did it agree with the previous experiment? What has happened with the theoretical calculations of g-2, and how has an experimental result puzzled the community? Do we have evidence for new physics or don’t we? Two of these three questions will be answered.
