I registered the website http://www.CliffordAlgebra.com . My purpose is to have a website that gives a decent education in the practical uses of Clifford Algebra, as I am interested in their applications to physics. Is there any desire over here for a more mathematical introduction to the subject? Please contact me if anyone is interested in contributing or in commenting on what they want. Carl By the way, I also registered http://www.measurementalgebra.com which will explain the Schwinger measurement algebra, and http://densitymatrix.com to explain the density matrix formulation for quantum mechanics. But these are more physics oriented subjects.
