Mathematica is a powerful active and dynamic medium for developing, exploring and communicating concepts and ideas having a mathematical underpinning.
It has an inbuilt programming language ideal for extending its capabilities to mathematical systems like Grassmann algebra. It also has a sophisticated mathematical typesetting capability which retains its computational attributes. The three Grassmann Algebra Volumes written by John Browne, use both features of Mathematica.
Mathematica can turn an exploration requiring days by hand into one requiring just minutes of computing time.

To use the GrassmannAlgebra package you will need Mathematica - which is available for most operating systems.

Links to the full text of two of John Browne's books (in READ ONLY format) can be found on this website.

All John's books are available in print form from Amazon. (see links this website)
