New Version

This is the version rom May 2003:

This older version contains some chapters (on quadratic forms, elliptic curves, and certain computer algebra systems) that I cut from the September 2004 version above, so it might still be of interest to you. Also see this remark about optimizing use of Mathematica by a reader.
