CERN Muon Ring Finds g Agrees with Electrodynamics Available to Purchase

To study the muon, catch one and watch its spin precess. Any difference between the precession rate you see and the one predicted by modern electrodynamics may be a clue to that puzzling enigma: What is the real difference between the muon and the electron? They appear to be alike except that the muon is 207 times as massive as the electron. But nature usually observes strict economy and does not display any particles that do not fit uniquely into the scheme of things.
