# 旋量

## 歷史

1927年，沃爾夫岡·包立將旋量應用至數學物理，當時他引入了自旋矩陣[5]隔年，保羅·狄拉克發現了相對論性的電子自旋理論，其中展示了旋量與勞侖茲群的關連。[6]於1930年代，狄拉克、皮亞特·海恩以及玻爾研究所的其他研究者建立了之類的玩具，作為旋量的教學以及旋量微積分的模型。

In their most general form, spinors were discovered in 1913 by the author of this work, in his investigations on the linear representations of simple groups*; they provide a linear representation of the group of rotations in a space with any number $n$ of dimensions, each spinor having $2^\nu$ components where $n = 2\nu+1$ or $2\nu$."
