I LOVE this book. I've had a hard copy for years. I always felt kind of lonely, though - it's such a niche topic that I had trouble finding anyone else interested enough to actually work through it :) So it's great to see it on the front page of HN.
Depending on how much code is in this book I may be interested in porting it to work with Racket. I am very interested in investigating Lisps and Lisplikes for numerical work, so I'd be happy to work through it in parallel with you, if you're still looking for a partner.
It looks pretty interesting. I studied physics in school and have been thinking about going back for an MS in computational modeling, so I'm thinking I'll start in on this book over the weekend just for fun. I've never used a Lisp-like language before, and it looks to be a pretty comprehensive review of classical mechanics as well.
Its software, scmutils, includes an emacs-like editor and execution environment called Edwin. Here's an oooold blog post I wrote about using GNU Emacs with scmutils instead: http://ai.redsymbol.net/2007/06/using-gnu-emacs-with-scmutil...
