Title: Final result from the Fermilab Muon g-2 Experiment

Abstract: On June 3, 2025, the Fermilab Muon g-2 Collaboration released its final determination for the muon's magnetic anomaly, a_μ = (g - 2)/2. Our result, after roughly a decade of design and construction and six years of data taking, was a_μ = 116 592 071(15)×10−11. The anomaly a_mu was determined from the ratio of the muon's anomalous precession frequency and the proton's Lamor precession frequency in the magnetic field of a 15 m diameter, 1.5 Tesla, superconducting muon storage ring. In this talk I'll discuss the science that motivated the  g-2 project and the techniques used to reach the 127-ppb precision. I'll also comment on the future work on the muon anomaly and the June 3, New York Times headline that the 'Muon Experiment was Hugely Successful but Clarifed Little'.
