[edit] Discovery of spinors

Somewhere in the article it should note that Cartan discovered the general mathematical form of spinors in 1913. --D. Estenson II 05:11, July 11, 2005 (UTC)

That is mentioned in the spinor article under History. Charles Matthews 07:52, 11 July 2005 (UTC)

I was thinking Cartan's article should also mention it. Maybe I'm wrong. --D. Estenson II 08:13, July 11, 2005 (UTC)

I wouldn't mind having this mentioned in some form. The opening sentence does emphasise Lie groups, of which the spinor work was just a facet. There is some question in my mind about how he shares credit with Hermann Weyl for opening up the theory. Charles Matthews 08:20, 11 July 2005 (UTC)

You are probably more of an expert on the subject than I, but in the introduction to Cartan's The Theory of Spinors he says, "In their most general mathematical form, spinors were discovered in 1913 by the author of this work, in his investigations on the linear representations of simple groups" and has a footnote for the Cartan's original publication in french. Weyl did work on the subject, but I don't know when he did it, all references I can find right now came far after 1913. --D. Estenson II 08:45, July 11, 2005 (UTC)
