James is astonishingly good at computational mathematics. I was one of the project members at IBM Research. James did some of the work, as did Barry Trager and Manual Bronstein. The project went by the name Scratchpad/Scratchpad II and became Axiom when it was sold to NAG. Axiom was sold for years as a commercial competitor to Mathematica and Maple. NAG released the code to me under the BSD license. I've been the lead developer on the Axiom project which is the open source version of the system (http://savannah.nongnu.org/projects/axiom). The Axiom Tutorial book (ISBN 1-4116-6597-X) lists approximately 170 people who contributed to Axiom so far.
