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.

Blaze: A High Performance C++ Math library
For typical game physics engines... not that much. Math libraries like Eigen or Blaze use lots of template metaprogramming techniques under the hood that can help when you're doing large batched matrix multiplications (since it can remove temporary allocations at compile-time and can also fuse operations efficiently, as well as applying various SIMD optimizations), but it doesn't really help when you need lots of small operations (with mat3 / mat4 / vec3 / quat / etc.). Typical game physics engines tend to use iterative algorithms for their solvers (Gauss-Seidel, PBD, etc...) instead of batched "matrix"-oriented ones, so you'll get less benefits out of Eigen / Blaze compared to what you typically see in deep learning / scientific computing workloads.
The codebases I've seen in many game physics engines seem to all roll their own math libraries for these stuff, or even just use SIMD (SSE / AVX) intrinsics directly. Examples: PhysX (https://github.com/NVIDIA-Omniverse/PhysX), Box2D (https://github.com/erincatto/box2d), Bullet (https://github.com/bulletphysics/bullet3)...

Recommended Physics Engine?
I don’t know of any books but here is the official documentation which includes an API reference. You can also find a lot of sample code snippets and examples on their GitHub.

On the other hand, PhysX is available under the MIT License and is both heavily used in games and also well documented with tons of sample code.

AMD Finally Opens Up Its Radeon Raytracing Analyzer "RRA" Source Code
The CPU implementation of PhysX is too, no reason you couldn't port that to run on AMD GPUs: https://github.com/NVIDIA-Omniverse/PhysX

Nvidia PhysX 5.0 is now open source
The LICENSE.md file on the repo doesn't mention BSD-3-Clause at all, it's just a copywrite notice that reads more like CC-BY than a software license. That's why I said it was weird.
Very! I just picked a random file: https://github.com/NVIDIA-Omniverse/PhysX/blob/release/104.0/physx/source/physx/src/NpArticulationJointReducedCoordinate.cpp
- GitHub - NVIDIA-Omniverse/PhysX: NVIDIA PhysX SDK - 5.0

Rust Game Physics Engines: PhysX, Rapier, XPBD & Others
Some other Rust game engines ship with their own physics engine. Fyrox, for example, has advanced 2D/3D physics, supporting rigid bodies, joints, ray casting and more. Godot too, which has community-led Rust bindings also has an in-built physics engine as well as a Godot-native extension using the Jolt physics engine. In fact, which is reported to be more performant than the official physics engine.

“This Is a Disaster:” Game Developers Scramble to Deal with Unity’s New Fees
I would say Bevy isn't really similar to Unity. Something like Fyrox - https://fyrox.rs/ - would be more similar. Bevy is more low level and lacks an editor (as of now, it's planned)

Help me find my game engine!
Fyrox might be an option, but for what you're looking (simple game logic, low performance concerns, desire for complete editor) for I'd probably choose Godot over it.

What is Rust's potential in game development?
Besides Bevy there’s also Fyrox Engine that looks very promising. https://fyrox.rs/

NANOVOID Devlog #1: Lua Scripting
We have our own engine. There aren't really full engines available in the Rust ecosystem. Bevy attempts to fill this, but it's far from being feature complete. There's also https://fyrox.rs/, but that's also work in progress. There's also https://rend3.rs/ which is just a 3d renderer, so you'll need to build the rest of the engine yourself.
