gave geometric algebra an Idea-section
That prompted a trip back to your discussion of geometric algebra, including lengthy extracts from Clifford algebra and the interpretation of quantum mechanics (pdf) and the claim
the electron is a quaternion
Further back you were helping us visualise the superstring.
Remember that Geometric Algebra was also the title of a lovely book by Emil Artin. It introduces Clifford algebras around page 190
It appears that there is also a page Geometric Algebra with very similar content.
@Dexter: In principle, a page with that title ought to be about Artin's book.
Thanks. I have fixed it now. Added disambiguation lines and made “Geometric Algebra” a stub for a category:reference page.
added pointer to
I have reverted and adjusted my original wording by mentioning real numbers as a ground field. (We really can’t claim that “geometric algebra is s subfield of Clifford algebra. It’s just playing with Clifford algebra in an ideosyncratic way.)
