This is absolutely awesome! We worked on the current one in sympy with Brian about a year ago, but didn't have time to continue on it.

It depends if you think the history of your 60 patches should be in sympy or not, e.g. if it is valuable (for debugging, learning how it works, etc.). The two patches that you proposed are definitely one of a good ways of doing that. I am at IRC (#sympy at freenode) in case you need help with the patches. Ondrej P.S. I have been working quite a lot on my QM notes here: http://certik.github.com/theoretical-physics/book/src/qft.html and we were also thinking a lot with Brian lately how to do the nonrelativistic limit of the relativistic formalism and obtain the known formulas from the second quantized nonrelativistic QM. And we both realied it'd be really cool to teach sympy do some (all?) of the manipulations. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy-patches" group.
