However, it is not
clear how the electron manages the rotational motion implied by its spin. If
the electron had a radius, the implied surface would have to be moving faster
than the speed of light, violating the theory of relativity. And experiments
show that the electron does not have a radius; it is thought to be a pure point
particle with no surface or substructure that could possibly spin.
In 1928, British
physicist Paul Dirac showed that the spin of the electron is intimately related
to the structure of space-time. His elegant argument combined quantum mechanics
with special relativity, Einstein's theory of space-time (famously represented
by the equation E=mc2).Dirac's equation, far from merely
accommodating spin, actually demands it. But while showing that relativistic
quantum mechanics requires spin, the equation does not give a mechanical
picture explaining how a point particle manages to carry angular momentum, nor
why this spin is two-valued.
