Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Rapier is a set of 2D and 3D physics engines written in Rust
I got sucked down a Geometric Algebra rabbit hole a few months ago, which seems like a remarkably concise and intuitive way to work in a very wide variety of geometries, including 2D, 3D, 4D+, non-euclidean etc. I've wondered if GA would make a good foundation for a physics engine...
There are a few small rust libraries that look interesting [1][2], but none with a lot of traction.
Has anyone looked into this?

Geometric Algebra to Geometric Computing Software Developers
The GA community in general is very small. So yes, tooling could be better, but IMO that is not even the problem. The lack of understanding how to use it is, because GA is not explicitly taught in schools or universities.
I have written a compiler which generates SIMD ready code for the desired GAs. You can then use that output as a normal library for your application.
