If FreeBSD runs on your new T61, you can install the Maxima port as a free
alternative to MATLAB and Mathematica. Maxima does symbolic math
and handles tensors. You can run Maxima code that proves that Einstein's
theory of relativity has a far-reaching logical inconsistancy in it
because the theory assumes torsion = 0 and curvature is nonzero.
Non-zero curvature implies torsion also is non-zero. 
See the code in paper 93 at
