Clifford Algebra
From MathWeb
An objects in Clifford Algebra can be thought of as a Complex Number only more so.
The basics
Two vectors in any number of dimensions can be multiplied according to this rule.
The first term is the dot product of vector algebra, and has a scalar result.
The second term is termed the wedge product. The result of this is termed a bivector because it is the product of two vectors.
Thus Clifford product can be expressed as
2 dimensions
Assume 2 orthogonal basis vectors of unit size
