After installing sympy goto sympy/example/galgebra and look at
physics_check_latex.py and run the code (if you have latex and a pdf
viewer installed).

You're in the right place :)
Is there any package related to *relativity* in SymPy?
Has anybody worked on it?
Do you mean special relativity or general relativity?
Regarding special relativity, I would suggest to create objects
representing 4-vectors, Lorentz tensors and spinor representation, and
represent the corresponding Lorentz/Poincaré transformations (both
tensor and spinor ones). I wrote some draft by myself which I did not
share, as it is incomplete, about tensor/spinor representations of
4-vectors and Dirac spinors, using the tensor module
http://docs.sympy.org/latest/modules/tensor/tensor.html
The tensor module approach to special relativity has some advantages
over the matrix/vector approach:
* you can work with more than 2 rank tensors (matrix is a 2 rank,
vector a 1 rank, the number of indices I mean).
* you can mark the tensor index type, i.e. the representation the
tensor/spinor undergoes with a Lorentz/Poincaré transformation.
I think that it would also be interesting to create objects for the
Dirac and Klein-Gordon fields, so we have a relativistic
generalization of the quantum module.
Concerning general relativity, have a look at this:

I hope to have a good time contributing to this project.
