Geometric Algebra, First Course, Episode 03: Relative Magnitudes and Scalars.

Показать описание
We grow our Vector to be a Scalar + Vector as we examine how to divide a geometric quantity by another. We see that it is OK to divide quantities that have the same aspect ("direction") even though we don't know how to calculate absolute magnitudes.

@28:16 A good physical example of a scalar + vector is the multivector current J in the GA form of Maxwell's equation (\nabla + (1/c) \partial/\partial t) F = J, where J has a scalar part (related to the traditional current density \rho) and a vector part (related to the current density) \vec{J}

I've been going back over some of your videos as I'm wanting to go down the road of creating GA-based UXes that will hopefully (🤞) be able to blend normal web UX with game-like UX. As such, I'm going to continue through these videos (using stemcstudio) but ultimately I am looking to either create or consume a library that doesn't require stemcstudio. I noticed that you have a davinci-eight library that looks much more serious, but I'm not seeing anything jump out at me in your videos that says it covers it. Do you have another course somewhere else on EIGHT? Do you have a video on your current status of working on it?

great content but the video is cut at the bottom so it is often not visible what you write :(

October 2023 - *to get a functional gist going* (gist 9a690f6ff56a6536a2241b14d5d25a9e), I had to add the final two `<script>` (jsdelivr cdn) tags in the `<head>`listed in jsxgraph's npmjs readme. (I can't paste the links or my YT comment will get filtered out.) With these two script tags added in stemcstudio's index.html, the code ran without error.
