@brandonshensley @seclark @giuspugl the `f1` model we inherited from PySM 2 has sharp features in the template, and causes complications with spherical harmonics transforms.
For example, if we eval…

From conversation with @aplavin:
In astronomy, one mostly encounters spherical caps and similar regions when working with coordinates that have uncertainties.
The uncertainties can be reported i…

For GeometryOps, I need three things fundamentally:
1. distance calculations
2. arc intersections (maybe robust, maybe not)
3. interpolation along the arc
It looks like SphericalGeodesics.jl is …

Hi @certik,
Thank you for maintaining the sympy.
Here is the code where simplify(Znm(3, -1, theta, phi).expand(func=True)) failed to cancel out the imaginary part symbolically.

In `basis.py` it looks a bit like you are adding linearly dependent basis functions for $l>1$
by explicitly adding all cartesian sph
```python
LMN_MAP = {
0: [(0, 0, 0)],

Hi all,
We wish to simulate a part of a spherical shell (e.g., within lat +-70) in a non-hydrostatic regime. Is there a readily available curvilinear grid framework to implement for such a setup?

**Describe the bug**
When the part described in the attached .scad file is exported to .stl, it produces a file with many errors. The errors are reported by PrusaSlicer. PS "repairs" the errors and p…

### Describe the issue linked to the documentation
We have an example that illustrates how to use the BIC score to tune the number of components and the type of covariance matrix parametrization he…

Question for @APEXCalculus.
Something that the engineering and physics students rely on a lot is the ability to write the "del" operator in other coordinates, and in particular, spherical coordinat…
