New issue 2254 by b-goo...@largestprime.net: Support for bitwise operations

sympy currently treats And and Or as logical operations (but a bit oddly,

http://code.google.com/p/sympy/issues/detail?id=2254
I think the problem here isn't that x | 1 == True, but that Or(x | 3) is
even allowed. In sympy, the Or, And, etc. operators

Of course these two are actually the same.
Thinking again, it is not quite that simple. In general f(F) is *very*

Thanks for informing me about the selection procedure, I will now

Hello Andy,
I'm working to submit a proposal on Sparse Matrices for this GSoC.
I wanted some help regarding the project. Would be very grateful if
you could help me.
According to my calculations, I'd take roughly 8 weeks to implement a
full SMatrix class and rewriting Matrix class to add GMPY

The current method for transforming sympy trees (used in the
printers, for example) can require some nested if-tests, even for some
simple cases like subtraction (addition of -1 multiplied by the first
arg), or division (mutiply by arg to the power of -1).
It would be nice to be able to

That's look very good. This would also allow to build customized math tree
from sympy tree.

Yes, that is the case. The difference between label and args is
deliberate and important:
* label == set of things that determine which state you have ==
quantum numbers usually.
Chris,
Welcome.
I’m a fourth year physics PhD student at UC Davis and I’m quite
interested in a few of your physics based GSoC projects. In
particular, I like the “Spin states and operators for arbitrary spin”
and “Position and momentum basis functions” projects. However,

Wecome!
My name is Luis F. Garcia, I'm a Physics junior undergrad in Tec de

First a bit of my background. My completed coursework so far has
