## A Survey of Geometric Algebra and Geometric Calculus

Mathematically, a geometric algebra may be defined as the Clifford algebra of a vector space with a quadratic form. Clifford's contribution was to define a new product, the geometric product, that united the Grassmann and Hamilton algebras into a single structure. Adding the dual of the Grassmann exterior product the "meet" allows the use of the Grassmann—Cayley algebra , and a conformal version of the latter together with a conformal Clifford algebra yields a conformal geometric algebra CGA providing a framework for classical geometries. The scalars and vectors have their usual interpretation, and make up distinct subspaces of a GA. Bivectors provide a more natural representation of the pseudovector quantities in vector algebra such as oriented area, oriented angle of rotation, torque, angular momentum, electromagnetic field and the Poynting vector. A trivector can represent an oriented volume, and so on. Rotations and reflections are represented as elements.

Alan Macdonald, Geometric Algebra :. Geometric algebra and its extension to geometric calculus unify, simplify, and generalize vast areas of mathematics that involve geometric ideas, including linear algebra, multivariable calculus, real analysis, complex analysis, and euclidean, noneuclidean, and projective geometry. They provide a unified mathematical language for physics classical and quantum mechanics, electrodynamics, relativity , the geometrical aspects of computer science e.
