    "abstract": "A simple real-space model for the free-electron wavefunction with spin is\nproposed, based on coherent vortices on the scale of h/mc, rotating at mc^2/h.\nThis reproduces the proper values for electron spin and magnetic moment.\nTransformation to a moving reference frame turns this into a wave with the de\nBroglie wavelength. The mapping of the real two-dimensional vector phasor to\nthe complex plane satisfies the Schrodinger equation. This suggests a\nfundamental role for spin in quantum mechanics.",
