@aescling @coriander the result of my clodvestigation:

Okay I watched much of the video. I can tell that the presenter has a very strong understanding of the determinant and the pedagogy here is similar to one I would use. The opening examples are also very good, I haven't seen such practical examples used to introduce the determinant

However, this video has a very "i have to give a presentation in class on the determinant and i was up til 3am last night" energy to it. The dots don't really connect. How the examples connect to the definition is not clear. How the properties really connect to the definition is not clear. And the lack of any of the precise formulas we use to compute the determinant in real life is egregious

The truth is that you can't really give a complete description of the determinant in 30 minutes. "Things should be as simple as possible, but no simpler."
