%0 Journal Article %T The Symmetry Underlying Spin and the Dirac Equation %A B. G. Sidharth %J Physics %D 1998 %I arXiv %X It is shown, in the context of a recent formulation of elementary particles in terms of, what may be called, a Quantum Mechanical Kerr-Newman metric, that spin is a consequence of a space-time cut off at the Compton wavelength and Compton time scale. On this basis, we deduce the Dirac equation from a simple coordinate transformation. %U http://arxiv.org/abs/quant-ph/9811032v1
