What people are saying

An interesting alternative to linear algebra is geometric algebra. I recommend googling around a bit for geometric algebra and trying out my implementation…

I heart your Grassman gradient vector field representations: https://github.com/chakravala/Grassmann.jl. They, heh heh, point the way toward representing aspects of physics and math that should be used far more frequently than they are now. They display the quirks that you could never apprehend looking at an equation. Your representations could eviscerate the representations of data base on paper-like metaphors. 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, th

In My advanced math skills are going down the drain
Recently I made a video presentation about geometric algebra, including the formulation of Maxwell's equations in GA: https://youtu.be/7hlDRLEhc8o 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.

Grassmann.jl dev looking for science funding

Greetings, I am the developer of Grassmann.jl working on creating more free software for engineers and researchers. I don't have a career and really need some funding to be able to continue creating more value in terms of basic science research and free software. My goal is to create software foundations based on geometric algebra for scientists and engineers. I believe this work to be essential for the advancement of science and it must be open source, so that it can be built on by future researchers. Please consider sponsoring Grassmann.jl at https://github.com/chakravala/Grassmann.jl
