Fascinating. The rule reminds me of this iconoclastic tour de force from the great David Hestenes, which takes intrinsic angular momentum seriously, i.e. electrons really are spinning or spiralling: The Zitterbewegung Interpretation of Quantum Mechanics http://geocalc.clas.asu.edu/pdf/ZBW_I_QM.pdf http://geocalc.clas.asu.edu/pdf/ZBW_I_QM.pdf "The idea that the electron spin and magnetic moment are generated by a localized circulatory motion of the electron has been proposed independently by many physicists. Schroedinger’s zitterbewegung (zbw) model for such motion is especially noteworthy, because it is grounded in an analysis of solutions to the Dirac equation. Surely, if the zbw is a real physical phenomena, then it tells us something fundamental about the nature of the electron..."
