This article presents a brief history of the appearance of electron spin in relativistic wave equations. Dirac derived his wave equation in 1928 with the intention to obtain an equation for the 'simplest' particle with spin zero. But, as Dirac later announced at the European Conference on Particle Physics (Budapest, 4–9 July 1977), it was a big surprise for him that the equation described the states of a particle with spin 1/2.

索默费尔德错了吗?(关于相对论波动方程中自旋出现的历史)

本文简要介绍了相对论波动方程中电子自旋的出现。狄拉克(Dirac)于1928年推导了他的波动方程,目的是获得一个自旋为零的“最简单”粒子的方程。但是,正如狄拉克(Dirac)后来在1977年7月4日至9日在布达佩斯举行的欧洲粒子物理学会议上宣布的那样,令他感到惊讶的是,该方程式描述了自旋1/2的粒子的状态。
