> Geometric algebra is, as the article points out, a more powerful version of the usual vector notation. But it is deficient in various ways when compared to tensor notation (for calculations) and differential forms (e.g. if you want to work basis-free). [I'm oversimplifying a bit, but a full discussion is too long for a comment here.] I have no opinion about the claims, but I loved the article, as I quickly saw the gains from this algebra for my very basic needs. After checking out your 2 suggested alternatives, I'm not so convinced they are easier to understand.
