What does HackerNews think of Grassmann.jl?
⟨Leibniz-Grassmann-Clifford⟩ multilinear differential geometric algebra
In the future, geometric algebra will likely be part of everything we do, but it is still very unknown as of now.
Sadly our leaders, the John Baez and Scott Aronson and people like that, prefer to think in Euler notation and WordPress posts. As Kurt Vonnegut said: So it goes.
The world of representation of difficult concepts using interactive 3D and elegant code is still in its infancy. You are not yet at the ground floor of the construction of a future elegant structure. You - and a few others - are in at the second basement.
Fortunately, the only way out is to look up!

Also, my implementation of geometric algebra in the Julia language, Grassmann.jl https://github.com/chakravala/Grassmann.jl
It helped me truly understand Maxwell's equations for the first time, understanding that it is not just some physical artifact but actually a natural foundational idea in pure mathematics applicable to physics.

and my own geometric algebra also:
It's an algebra which unifies linear algebra with quaternions and tensors.
