Abstract

In Sect. 1.2.7, Chap. 1, it is found that the electron spin torque is counterbalanced by the chiral electron density. In Sect. 1.2.8, Chap. 1, it is found that the spin vorticity of electron contributes to the kinetic momentum of electron, which raises a simple but “odd” question: what is momentum of electron spin? In this Chapter, we shall show that the origin of both the chiral nature and the kinetic nature is manifest in the principle of equivalence in general relativity.
