I might have a spare computer that I can dedicate to math research, so I'm searching for free software and formulae collections (preferebly in pdf, tex, ps...) to put on it. It won't have internet and I want to minimize data transfer back and forth

CAS is taken care of by Axiom under TeXmacs, and Octave. I haven't been able to find a free and decent CAD/CAE program though, I'm thinking one might no exist

As for a formulas, I have basics phyics and dating. I need impression forensics, fire/arson (ok so I just want those ), and engineering (fluid flows, stress handling, vibrations, etc.)

Thanks for the help
