Geometric Algebra – A collection of useful resources
Introduced by Hermann Grassmann and greatly expanded by William Kingdon Clifford during the 19th century, Geometric Algebras provide a proper abstract framework for the treatment of geometrical vector operations that extend naturally to general dimensions. Their concise conceptualization yields elegant and peculiarly coherent constructs, in contrast with the intricacies of vector calculus. Because of the geometric origin of their structures and close relation with quadratic forms, they turn useful in a wide range of applications in theoretical and applied sciences across several fields.
